Fostering retention of word learning: The number of training sessions children retrieve words positively relates to post-training retention

During vocabulary instruction, it is important to teach words until their representations are robust enough to be retained. For adults, the number of training sessions a target item is successfully retrieved during training predicts the likelihood of post-training retention. To assess this relationship in children, we reanalyzed data from Gordon et al. (2021b, 2022). Four- to six-year-old children completed six training days with word form-object pairs and were tested one month later. Results indicate that the number of training sessions that a word form was retrieved was positively related to post-training retention. We discuss implications for vocabulary instruction and interventions.

Embedding retrieval practice in undergraduate biochemistry teaching using PeerWise

Retrieval practice is an evidence-based approach to teaching; here, we evaluate the use of PeerWise for embedding retrieval practice into summative assessment. PeerWise allows anonymous authoring, sharing, answering, rating, and feedback on peer-authored multiple choice questions. PeerWise was embedded as a summative assessment in a large first-year introductory biochemistry module. Engagement with five aspects of the tool was evaluated against student performance in coursework, exam, and overall module outcome. Results indicated a weak-to-moderate positive but significant correlation between engagement with PeerWise and assessment performance. Student feedback showed PeerWise had a polarizing effect; the majority recognized the benefits as a learning and revision tool, but a minority strongly disliked it, complaining of a lack of academic moderation and irrelevant questions unrelated to the module. PeerWise can be considered a helpful learning tool for some students and a means of embedding retrieval practice into summative assessment.

No Simple Solutions to Complex Problems: Cognitive Science Principles Can Guide but Not Prescribe Educational Decisions

Cognitive science of learning points to solutions for making use of existing study and instruction time more effectively and efficiently. However, solutions are not and cannot be one-size-fits-all. This paper outlines the danger of overreliance on specific strategies as one-size-fits-all recommendations and highlights instead the cognitive learning processes that facilitate meaningful and long-lasting learning. Three of the most commonly recommended strategies from cognitive science provide a starting point; understanding the underlying processes allows us to tailor these recommendations to implement at the right time, in the right way, for the right content, and for the right students. Recommendations regard teacher training, the funding and incentivizing of educational interventions, guidelines for the development of educational technologies, and policies that focus on using existing instructional time more wisely.

Lower constraint testing enhances the testing effect for some contextual details but not others

INTRODUCTION

Retrieval practice has been shown to be an effective means of learning new information, a memory phenomenon known as the testing effect or the retrieval practice effect. Some work suggests that the magnitude of the testing effect can be enhanced when the test used for retrieval practice uses fewer cues to retrieve previously studied information. It is unclear, however, whether such testing benefits extend to peripheral contextual details associated with studied materials (e.g., location where stimuli appear, font color in which items are presented, etc.). In this experiment, we examine both item memory (i.e., memory for the studied items) and context memory under conditions where the intervening test offers fewer cues (i.e., lower constraint) compared to more cues (higher constraint) to better understand item and context memory testing effects.

METHODS

Participants first studied word pairs presented in one of eight locations as well as in either red or green font color. Then, in the re-exposure phase, participants processed materials in two types of intervening tests (lower constraint and a higher constraint test) as well as in a restudy condition, before a final memory test.

RESULTS

For item memory, results showed that memory was better in the lower constraint testing condition compared to both the higher constraint testing condition as well as the restudy (control) condition. For context memory, results indicated improved memory for location context under lower constraint testing compared to both higher constraint testing and restudy conditions. There was no difference in memory, however, for color context across all conditions.

CONCLUSION

Overall, these findings suggest that providing fewer cues to aid retrieval in the intervening test can induce better memory for both items as well as some contextual details.

Re-examining the testing effect as a learning strategy: the advantage of retrieval practice over concept mapping as a methodological artifact

Several previous studies appear to have demonstrated that studying with retrieval practice produces more learning than studying with concept mapping, a finding based on which an extended use of retrieval practice in educational practice was recommended. However, a closer examination of the methods used in these previous studies reveals a crucial confounding variable: Whereas participants in the concept mapping conditions performed a concept mapping task without any subsequent memorizing of the learning material, participants in the retrieval practice conditions performed not only retrieval practice but also an additional memorization task, which doubled the total memorization time. The present preregistered study examined whether the advantage observed in the retrieval practice condition over the concept mapping condition in previous studies was actually driven by additional memorization rather than by retrieval practice. While we replicated the previous finding that retrieval practice in combination with additional memorizing produces more learning than concept mapping without additional memorizing, this advantage of retrieval practice over concept mapping vanished when participants in the concept mapping condition, too, memorized the learning material after having created a concept map. These findings demonstrate that the assumed advantage of retrieval practice over concept mapping in fact represents a methodological artifact. Besides serving as a reminder of the importance of a solid methodology, the present study also illustrates the importance of using of an adequate terminology. Depicting a learning strategy condition as "retrieval practice" when the condition actually encompasses not only retrieval practice but also additional memorizing obfuscates the possibility that observed memory advantages may not be fueled by retrieval practice, i.e., the learning strategy as such. We conclude by giving an outlook on the ramifications of our findings for cognitive and educational psychology.

The Effectiveness of Spaced Learning, Interleaving, and Retrieval Practice in Radiology Education: A Systematic Review

PURPOSE

Radiology is a highly complex field that requires mastery over an ever-expanding body of knowledge. Spaced learning, interleaving, and retrieval practice are evidence-based learning strategies that enhance long-term retention of information. The aim of this systematic review is to assess the effectiveness of these interventions in the setting of radiology education.

METHODS

The authors searched MEDLINE, Embase, PsycInfo, ERIC, and forward and backward citations for studies published between database inception and February 19, 2023. Eligibility criteria for included studies were randomized and quasi-randomized controlled trials that investigated the impact of spaced, interleaved, or retrieval practice on knowledge retention of medical trainees after education related to medical imaging as assessed by postinterventional examination scores.

RESULTS

Of 1,316 records reviewed, 8 studies met eligibility criteria. Two studies investigated spaced learning, two studies interleaving, and six studies retrieval practice, including two trials that evaluated interventions incorporating both spaced learning and retrieval practice. Five of eight studies reported statistically significant differences between interventional and control groups on either immediate or delayed postinterventional examinations.

CONCLUSIONS

Despite extensive evidence in support of spaced, interleaved, and retrieval practice within the broader literature, few studies have examined the effectiveness of these strategies in radiology education. Additional trials are required to evaluate the usefulness of incorporating these techniques into educational programs related to medical imaging.

Retrieval practice reduces relative forgetting over time

There is overwhelming evidence in the literature that retrieval practice of studied material can lead to better final recall than restudy of the same material. Far less clear is whether this recall benefit is accompanied by reduced subsequent forgetting over time. This study revisited the issue in two experiments by comparing the effects of retrieval practice - with and without feedback -, restudy, and a no-practice condition on recall across different delay intervals ranging between three minutes and several days. We fitted power functions of time to the recall rates of each practice condition and compared relative forgetting rates between conditions. The comparisons showed that relative forgetting was reduced after retrieval practice relative to restudy, the relative forgetting rate after retrieval practice was unaffected by the presence of feedback, and forgetting after restudy did not differ from the no-practice condition. Together with other findings in the literature, the results provide evidence that retrieval practice reduces relative forgetting over time.

Transitive inference and the testing effect: Retrieval practice impairs transitive inference

There is substantial interest in the extent to which the testing effect (the finding that retrieval practice enhances memory) extends to more complex forms of learning, especially those entailing greater element interactivity. Transitive inference (TI) requires just such interactivity, in which information must be combined across multiple learning elements or premises to extract an underlying structure. Picklesimer et al. provided preliminary evidence that retrieval practice fails to enhance, and actually disrupts, TI. This study assessed the generality of that result. The current experiments employed a seven- or eight-element TI paradigm in which participants initially learned a set of premise pairs (e.g., A > B, B > C, and C > D) and then engaged in either restudy or retrieval practice of the premise pairs before taking a final test that assessed memory for the original premise pairs and one's ability to make TIs (e.g., to infer that B > D). Experiments 1 and 2 used pictorial materials and simultaneous presentation of premises during learning, a form of presentation that has induced testing effects on other forms of inference. For TI, the results were unchanged from Picklesimer et al.-TI was worse for retrieval practice than restudy. Experiment 3 used verbal materials and likewise found worse TI for retrieval practice. A small-scale meta-analysis combining the current experiments with those of Picklesimer et al. revealed a significant negative testing effect on TI (d = -0.37). Although retrieval practice enhances many aspects of memory, this fundamental aspect of human reasoning may be impaired by retrieval practice.

Retrieval practice benefits for spelling performance in fifth-grade children

Retrieval practice typically benefits learning in children, although little is known about the benefits of retrieval practice for learning spelling. We investigated this issue in three experiments with fifth-grade children from a low-income area of Brazil. In the experiments, children first read a list of words (study), and after a short interval wrote down the studied words after hearing and rereading them (copy) or after only hearing them (retrieval practice). After an interval of 4 days, spelling performance was greater for words from the retrieval practice condition than for words from the copy condition, but only when immediate corrective feedback was provided (Experiment 3). The current findings, therefore, suggest that retrieval practice followed by corrective feedback is an effective strategy to improve spelling performance of fifth-grade children.

Test Experience, Direct Instruction, and Their Combination Promote Accurate Beliefs about the Testing Effect

Practice testing is a highly robust learning strategy that promotes long-term retention, especially in comparison to more passive strategies such as restudying-a finding referred to as the testing effect. However, learners do not always appreciate the memorial benefits of practice testing over restudying, which could limit their use of practice testing during self-regulated learning. The current investigation explored the extent to which learners' metacognitive judgments about the testing effect can be improved via test experience, direct instruction, or a combination of both techniques. Prolific participants underwent two learning cycles. In the first cycle, participants were randomly assigned to either (a) experience a testing effect in their own memory performance (i.e., study unrelated word pairs, practice half the pairs through restudying and half through testing with correct-answer feedback, complete a critical test on the pairs, and receive feedback regarding their performance after using each strategy); (b) imagine they had to learn word pairs and read a passage on the purported benefits of practice testing; or (c) undergo both procedures. In the second cycle, all participants learned a novel set of word pairs. Across both learning cycles, participants estimated memory performance for material learned through testing versus restudying. Both test experience and direct instruction-independently and in combination-led to more accurate memory estimates across learning cycles, but no technique was more effective than the other. In summary, people can learn about the memorial benefits of practice testing when they experience a testing effect on their own memory performance and/or when they receive instruction about its benefits.

Is practice good enough? Retrieval benefits students with ADHD but does not compensate for poor encoding in unmedicated students

Introduction

A significant proportion of currently enrolled college students receive support for attention deficit/hyperactivity disorder (ADHD) and these students are often at risk of academic failure. Retrieval practice or self-testing is an effective, accessible, and affordable tool for improving academic performance. Three recent studies found conflicting results with regards to the effectiveness of retrieval practice in this population.

Methods

The present study compared 36 individuals with ADHD to 36 controls. Participants studied Swahili-English word pairs that varied in difficulty. Half of the pairs were repeatedly studied, and the other half repeatedly tested.

Results

On a final test, all participants showed a benefit of retrieval practice relative to restudy and participant status did not moderate the effect. However, unmedicated individuals with ADHD performed worse overall, both during the encoding phase and on the final test, whereas medicated participants were not significantly different from controls.

Discussion

An examination of self-reported encoding strategies found unmedicated participants used fewer deep strategies at encoding, consistent with prior work on ADHD and memory. Although retrieval practice is effective in this group, improved strategy use may be necessary to ensure performance that is fully equivalent to that of students without ADHD.

Collaborative Retrieval Practice Reduces Mind-Wandering During Learning

Research has shown engaging in retrieval practice can reduce the frequency of mind-wandering. However, no prior research has examined how engaging in collaborative (as compared to individual) retrieval practice impacts mind-wandering during learning. In the current experiment, participants were asked to study a list of words, followed by retrieval practice that either occurred collaboratively (as a dyad) or individually. During retrieval practice, participants provided self-reports as to whether they were on task or off task. Following retrieval practice, all participants completed an individual final test. Of greatest interest, the results showed that engaging in collaborative retrieval practice decreased the frequency of mind-wandering during learning. In addition, and consistent with prior collaborative learning research, collaborative inhibition during practice and postcollaborative benefits on the final test were observed. The current results provide the first demonstration of an additional benefit to using collaborative retrieval practice: This technique reduces the frequency of mind-wandering.

Educational Videos Versus Question Banks: Maximizing Medical Student Performance on the United States Medical Licensing Examination Step 1 Exam

Objective The aim of this research was to determine if medical students' use of the active study strategy of working practice questions is associated with improved performance on the United States Medical Licensing Examination (USMLE) Step 1 exam when compared to students who used the passive study strategy of watching educational videos. Methods The study used a correlational design. Participants were students from two cohorts in a United States medical school (N=164 and N=163) who completed their first two years and took the USMLE Step 1 exam. Data collected retrospectively included the number of practice questions completed, educational videos watched, Step 1 exam scores, average scores on in-class exams, and scores on the Medical College Admission Test (MCAT). Results The number of videos watched was negatively and significantly correlated with the Step 1 score for cohort 2022 (r= -0.294, α=0.01) and cohort 2023 (r= -0.175, α=0.05). The number of practice questions worked was positively and significantly correlated with the Step 1 score for cohort 2022 (r=0.176, α=0.05) and cohort 2023 (r=0.143 though not significant). The number of practice questions was a significant positive predictor of Step 1 score for cohort 2022 (β=0.141, p=0.017) and cohort 2023 (β=0.133, p=0.015). Videos were significant negative predictors for cohort 2023 (β= -0.118, p=0.034). Conclusions Answering practice questions appears to be a more effective study method than passively watching videos. Though other studies have supported the use of active learning methods, this study is unique in finding a negative correlation between test scores and the number of educational videos watched. Medical students should be urged to make the most effective use of study time by incorporating working practice questions and limiting watching educational videos.

Improving Knowledge of Top 200 Medications Through Retrieval Practice, Content Alignment, and Autonomous Learning

Objective. To determine the impact of the holistic redesign of top 200 medications learning activities within a Doctor of Pharmacy (PharmD) curriculum by comparing student performances on a comprehensive examination before and after the redesign.Methods. During a curricular revision at The Ohio State University College of Pharmacy that began with the class of 2020, learning activities involving the top 200 medications were implemented that involved repeated retrieval and mastery concepts, alignment with therapeutic coursework, and autonomous learning regarding the top 200 medications. A high-stakes comprehensive top 200 medications examination was administered to students at the end of their third professional year both before and after implementation of these activities. The difference in the percentage of students who achieved a satisfactory score on the comprehensive examination was compared between cohorts prior to and following the curricular redesign.Results. The study analyzed results from 134, 130, and 120 students from three PharmD classes (one before and two after the redesign of top 200 medications activities). Following the redesign, a higher percentage of students achieved a satisfactory score of 85% on the examination (class of 2020: 116/130, 89.2%; class of 2022: 107/120, 89.2%) compared to before the redesign (class of 2019: 88/134, 65.7%).Conclusion. The combination of repeated retrieval and mastery, alignment with therapeutic coursework, and development of autonomous learning can significantly increase student knowledge and retention of top 200 medications.

Use of practice tests with immediate feedback in an undergraduate molecular biology course

Multiple studies have shown that testing contributes to learning at all educational levels. In this observational classroom study, we report the use of a learning tool developed for a Genetics and Molecular Biology course at the college level. An interactive set of practice exams that included 136 multiple choice questions (MCQ) or matching queries was developed in the open-source Moodle platform. All MCQ questions contained four answer choices and configured for immediate feedback upon answering. Feedback consisted of providing the right answer and a short explanation of the learning objective examined. The interactive material was tested and refined for several semesters. Usefulness of this tool was assessed in two distinct settings: (1) during a face-to-face semester (Fall 2019) by comparing the grades in a final departmental exam between students who used the tool and those who did not, and (2) during an online semester (Fall 2020) by analyzing the grades in the first and last attempts on study sessions and students' performance in monthly exams. We found that when solving practice tests, students obtained a significantly higher scores in the last attempt compared with their first attempt, and that students who used the material performed better than those who did not. In all cases, answering the practice exams was optional, but students made full use of them preferentially during the online semester. This classroom research exemplifies the documented effectiveness of practice tests enhanced with feedback in biological sciences education through an open-source learning platform.

Impact of an Online Question Bank on Resident In-Training Exam Performance

OBJECTIVE

In-training exams (ITEs) are administered annually to Obstetrics and Gynecology (OBGYN) residents and have been demonstrated to correlate with success on licensing examinations. Our study objective was to determine the impact of a question bank and mock exam on the performance of Council on Resident Education in Obstetrics and Gynecology (CREOG) ITEs. Secondarily, we investigated the correlation between the extent of question bank usage and performance on the exam.

METHODS

Pre-post intervention study of resident performance on CREOG ITE before and after implementation of the question bank and mock ITE at Indiana University in 2018. Performance was measured as year-to-year improvement in percent correct on ITE exams. Scores were excluded if a resident did not have a prequestion bank score report or if they did not sit for all eligible ITE exams.

RESULTS

There were 51 OBGYN residents at Indiana University during the study period, with 38 available for analysis (75%). Before implementation, average year-to-year improvement for PGY1-2, PGY2-3 and PGY3-4 classes were 0.60%, 1.0% and -1.6%, respectively. After implementation, all resident classes had significant improvements in ITE scores of 6.6% (P < .01), 9.0% (P < .01), and 7.2% (P < .01), respectively. There was a moderate program-wide correlation between the number of questions completed and the percent improvement on the ITE of R = 0.36 (P = .046).

CONCLUSIONS

Our study demonstrated that access to a question bank and mock ITE significantly improved CREOG ITE performance of OBGYN residents at Indiana University.

How retrieval practice and semantic generation affect subsequently studied material: an analysis of item-level effects

The forward testing effect (FTE) refers to the finding that retrieval practice of previously studied material can facilitate recall of newly studied (critical) material. Such interim retrieval practice can also lead to a differential FTE, i.e., a more pronounced FTE for items at early than later serial positions in the critical material. The present study examined whether this differential FTE also holds with interim semantic generation of extra-list items, and whether it is influenced by study material. Consistent with prior work, the results of two experiments showed that both interim retrieval practice and interim semantic generation induce the general (list-level) FTE when unrelated study lists are applied, whereas retrieval practice only creates the effect with categorised study lists. Critically, however, the differential FTE was present in response to retrieval practice but absent in response to semantic generation. This pattern held regardless of which material was studied, thus experimentally dissociating the general (list-level) from the differential (item-level) FTE. The findings may suggest that retrieval practice, but not semantic generation, induces a reset of the encoding process which promotes attentional encoding such that a more pronounced FTE arises for early than middle and late serial positions in the critical list.

Do Domain Knowledge and Retrieval Practice Predict Students' Study Order Decisions?

Learning complex concepts is necessary for student success, but it is often challenging. Learning such concepts can be influenced by students' study order choices during learning to switch to a new category (interleaved study order) or stay within the same category (blocked study order). Students often prefer stay decisions during learning and make relatively few switch decisions; however, an open question is whether students' switch decisions are related to their level of prior knowledge in the domain and the learning strategy they use (retrieval practice versus study). To examine these relationships, we recruited undergraduate students from an introductory geology course. Prior to the course modules on rock classification, students self-rated their knowledge, took a prior knowledge test, classified rock exemplars by completing study or retrieval practice trials, and made study order choices. Students then completed assignments and attended lectures in their geology course on igneous, sedimentary, and metamorphic rocks. Next, students self-rated their knowledge, took a new prior knowledge test, completed study or retrieval practice trials, made study order decisions, took final classification tests, and self-reported beliefs about study order choices. Even though students' knowledge increased after course modules on rock identification, and most students believed that domain knowledge impacts study decisions, prior knowledge did not predict students' switch decisions. In contrast, students who completed retrieval practice trials made substantially more switch decisions (i.e., interleaved study) than did students who completed study trials.

Using the study cycle model to support better student learning: a faculty guide

Despite years of varied school experiences, many college students do not have adaptable study methods that allow them to collect, organize, and reorganize information to critically assess what they know and what they need help with until after a poor exam performance. Faculty are frequently called on to help students become better learners. In addition, as the tasks and complexity of the material become more challenging, students will need to adopt new study habits and adapt them to each new learning opportunity to reach their goals. This article describes an evidence-based framework that teachers can share with students that will support better studying habits leading to deeper learning.NEW & NOTEWORTHY Many college students do not have adaptable methods habits that allow them to get the most out of in-class time and structure their out-of-class study time. As a result, faculty are frequently called on to help students become better learners. This article describes an evidence-based framework focusing on learning anatomy and physiology examples that faculty can share with students to support better studying habits leading to deeper learning.

When Memory and Metamemory Align: How Processes at Encoding Influence Delayed Judgment-of-Learning Accuracy

Judgments of learning are most accurate when made at a delay from the initial encoding of the assessed material. A wealth of evidence suggests that this is because a delay encourages participants to base their predictions on cues retrieved from long-term memory, which are generally the most diagnostic of later memory performance. We investigated the hypothesis that different types of study techniques affect delayed JOL accuracy by influencing the accessibility of cues stored in long-term memory. In two experiments, we measured the delayed-JOL accuracy of participants who encoded semantically unrelated and weakly related word pairs through one of three study techniques: reading the pairs twice (study practice), generating keywords (elaborative encoding), or taking a cued-recall test with feedback (retrieval practice). We also measured the accessibility, utilization, and diagnostic quality of two long-term memory cues at the time of the delayed JOL: (a) retrieval of the target, and (b) noncriterial cues (retrieval of contextual details pertaining to the encoding of the target). We found that the accessibility of targets was positively associated with delayed-JOL accuracy. Further, we provide evidence that when study techniques enhance the accessibility of targets, they likewise enhance delayed-JOL accuracy.

An examination of retrieval practice and production training in the treatment of lexical-semantic comprehension deficits in aphasia

OBJECTIVE

Little research has addressed the treatment of lexical-semantic comprehension deficits (i.e., difficulty retrieving the meanings of words) in people with aphasia (PWA). Research suggests that practice retrieving names for depicted objects from long-term memory (production-based retrieval practice) more strongly benefits word retrieval for production in PWA compared to errorless learning (i.e., word repetition), which eschews retrieval practice. This study assessed whether production-based and comprehension-based retrieval practice enhance performance on errorful word-comprehension items in PWA measured relative to nonretrieval forms of training and untrained control items.

METHOD

In a within-participant group study of PWA, errorful comprehension items were assigned to (a) a production-based training module (retrieval practice vs. errorless learning); (b) a comprehension-based training module (a receptive form of retrieval practice vs. restudy). Each module comprised one training session and a 1-day and 1-week comprehension posttest on the module's trained items and an untrained item set.

RESULTS

The comprehension module conditions produced similar and superior posttest performance relative to untrained items. Both production module conditions improved posttest performance relative to untrained items, with retrieval practice conferring more durable learning and generalization indicative of refinement of semantic representations compared to errorless learning.

CONCLUSIONS

Results suggest comprehension- and production-based forms of training are both beneficial for improving lexical-semantic deficits in aphasia, with production-based retrieval practice conferring additional benefits to the targeted deficit compared to errorless learning. Future studies should examine these learning factors in schedules of training more commensurate with clinical practice and in other neurological populations (e.g., semantic dementia).

Testing improves performance as well as assesses learning: A review of the testing effect with implications for models of learning

Taking a test of previously studied material has been shown to improve long-term subsequent test performance in a large variety of well controlled experiments with both human and nonhuman subjects. This phenomenon is called the testing effect. The promise that this benefit has for the field of education has biased research efforts to focus on applied instances of the testing effect relative to efforts to provide detailed accounts of the effect. Moreover, the phenomenon and its theoretical implications have gone largely unacknowledged in the basic associative learning literature, which historically and currently focuses primarily on the role of information processing at the time of acquisition while ignoring the role of processing at the time of testing. Learning is still widely considered to be something that happens during initial training, prior to testing, and tests are viewed as merely assessments of learning. However, the additional processing that occurs during testing has been shown to be relevant for future performance. The present review offers an introduction to the historical development, application, and modern issues regarding the role of testing as a learning opportunity (i.e., the testing effect). We conclude that the testing effect is seen to be sufficiently robust across tasks and parameters to serve as a compelling challenge for theories of learning to address. Our hope is that this review will inspire new research, particularly with nonhuman subjects, aimed at identifying the basic underlying mechanisms which are engaged during retrieval processes and will fuel new thinking about the learning-performance distinction.

The Retrieval Practice Hypothesis in Research on Learning by Teaching: Current Status and Challenges

To explain why students learn effectively by teaching, explaining to others in particular, Koh and colleagues advanced the retrieval practice hypothesis, which attributes the learning benefits entirely to the effect of practicing retrieval, that is, effortfully recalling to-be-taught information for the provision of instructional explanations. After delineating the rationale behind the retrieval practice hypothesis, the current situation of research, and the limitations of the existing approach, this paper proposes three tests for the evaluation of the hypothesis that address (1) whether explaining to others after initial studying surpasses restudying in learning performance, (2) whether the amount of effort to retrieve to-be-taught information from memory moderates the learning effects of explaining to others, and (3) whether the degree of elaboration during retrieval practice positively predicts the outcomes of learning by merely recalling to-be-taught information. Evidence is examined regarding whether each test is passed, and future directions for research on the retrieval practice hypothesis are discussed.

Interleaving Retrieval Practice Promotes Science Learning

Can interleaved retrieval practice enhance learning in classrooms? Across a 4-week period, ninth- through 12th-grade students (N = 155) took a weekly quiz in their science courses that tested half of the concepts taught that week. Questions on each quiz were either blocked by concept or interleaved with different concepts. A month after the final quiz, students were tested on the concepts covered in the 4-week period. Replicating the retrieval-practice effect, results showed that participants performed better on concepts that had been on blocked quizzes (M = 54%, SD = 28%) than on concepts that had not been quizzed (M = 47%, SD = 20%; d = 0.30). Interleaved quizzes led to even greater benefits: Participants performed better on concepts that had been on interleaved quizzes (M = 63%, SD = 26%) than on concepts that had been on blocked quizzes (d = 0.35). These results demonstrate a cost-effective strategy to promote classroom learning.

How do college students use digital flashcards during self-regulated learning?

Over the past two decades, digital flashcards - that is, computer programmes, smartphone apps, and online services that mimic, and potentially improve upon, the capabilities of traditional paper flashcards - have grown in variety and popularity. Many digital flashcard platforms allow learners to make or use flashcards from a variety of sources and customise the way in which flashcards are used. Yet relatively little is known about why and how students actually use digital flashcards during self-regulated learning, and whether such uses are supported by research from the science of learning. To address these questions, we conducted a large survey of undergraduate students (n = 901) at a major U.S. university. The survey revealed insights into the popularity, acquisition, and usage of digital flashcards, beliefs about how digital flashcards are to be used during self-regulated learning, and differences in uses of paper versus digital flashcards, all of which have implications for the optimisation of student learning. Overall, our results suggest that college students commonly use digital flashcards in a manner that only partially reflects evidence-based learning principles, and as such, the pedagogical potential of digital flashcards remains to be fully realised.

Interactive retrieval practice in renal physiology improves performance on customized National Board of Medical Examiners examination of medical students

Retrieval practice improves long-term retention. Use of interactive retrieval practice in large group, in-person and online live classes, in combination with outside resources, is unreported for medical physiology classes. The primary study purpose was to compare student cohorts' performance with or without retrieval practice in renal physiology classes, relative to the national average on customized national examinations in renal physiology, nonphysiology, and all questions. The secondary purpose was to examine the students' educational experience. For the primary purpose, we used a nonequivalent group, posttest-only design. For the secondary purpose, we used cross-sectional and qualitative designs. We analyzed examination results of 684 students in four academic years. For renal physiology questions, students performed significantly better in years with retrieval practice compared with years without it (P < 0.001). There was no change in nonphysiology scores over the four years. Performance in all questions, too, significantly improved (P < 0.001). A large majority (86%) of students indicated retrieval practice helped them learn renal physiology. Student ratings of quality in online classes, which featured interactive retrieval practice, were higher than that of in-person classes (P < 0.001). Qualitative analysis revealed students found interactive retrieval practice, scaffolding, outside resources, and the instructor's teaching style helpful. Educators in medical physiology classes can use our findings to implement interactive retrieval practice.

Retrieval Practice Is Effective Regardless of Self-Reported Need for Cognition - Behavioral and Brain Imaging Evidence

There is an emerging consensus that retrieval practice is a powerful way to enhance long-term retention and to reduce achievement gaps in school settings. Less is known whether retrieval practice benefits performance in individuals with low intrinsic motivation to spend time and effort on a given task, as measured by self-reported need for cognition (NFC). Here, we examined retrieval practice in relation to individual differences in NFC by combining behavioral and functional magnetic resonance imaging (fMRI) data. Using a within-subject design, upper-secondary school students (N = 274) learned a language-based material (Swahili-Swedish word-pairs), with half of the items by means of retrieval practice with feedback and half by study only. One week later, the students were tested on the word-pairs either in the classroom (n = 204), or in a fMRI scanner (n = 70). In both settings, a retrieval practice effect was observed across different levels of NFC (high or low). Relatedly, comparable fMRI effects were seen in both NFC subgroups. Taken together, our findings provide behavioral and brain-imaging evidence that retrieval practice is effective also for individuals with lower levels of NFC, which is of direct relevance for educational practice.

The dual-process perspective and the benefits of retrieval practice in younger and older adults

The testing effect is often considered a recollection-related phenomenon. However, recent work has observed a benefit of testing to both recollection and familiarity on immediate and delayed final tests. Further, although aging populations show marked declines in recollection, older and younger adults often benefit similarly from testing. This finding suggests that the testing effect in older adults may function via relatively preserved familiarity and lends further support to the hypothesis that the testing effect does not function solely via recollection-related processes. The current study builds on this work to better understand the mechanisms from the dual-process perspective that underlie the testing effect in both younger and older adults. To this end, younger (18-22 year old) and older (65-82 year old) adults studied words, took cued-recall tests on half of the words, and took a final Remember-Know recognition test on all words immediately or after a 1-day delay. At both delays, older and younger adults exhibited a testing effect in both recollection and familiarity, although the magnitude of the testing effect in recollection was reduced for older relative to younger adults. Implications for theories of the testing effect and its application in older adult populations are explored.

Effortful Retrieval Practice Effects in Lexical Access: A Role for Semantic Competition

Word retrieval difficulty (lexical access deficit) is prevalent in aphasia. Studies have shown that practice retrieving names from long-term memory (retrieval practice) improves future name retrieval for production in people with aphasia (PWA), particularly when retrieval is effortful. To explicate such effects, this study examined a potential role for semantic competition in the learning mechanism(s) underlying effortful retrieval practice effects in lexical access in 6 PWA. Items were trained in a blocked-cyclic naming task, in which repeating sets of pictures drawn from semantically-related versus unrelated categories underwent retrieval practice with feedback. Naming accuracy was lower for the related items at training, but next-day accuracy did not differ between the conditions. However, greater semantic-relatedness of an item to its set in the related condition was associated with lower accuracy at training but higher accuracy at test. Relevance to theories of lexical access and implications for naming treatment in aphasia are discussed.

Retrieval practice transfer effects for multielement event triplets

Retrieval practice (RP) leads to improved retention relative to re-exposure and is considered a robust phenomenon when the final test conditions are identical to RP conditions. However, the extent to which RP 'transfers' to related material is less clear. Here, we tested for RP transfer effects under conditions known to induce integration of associated material at encoding, which may make transfer more likely. Participants learned multielement triplets (locations, animals and objects) and one pairwise association from each triplet was tested through RP, re-exposed, or not re-exposed (control). Two days later participants completed a final test of all pairwise associations. We found no evidence for an RP effect compared to re-exposure, but both tested/re-exposed pairs were better remembered than the not re-exposed control condition. We also found that transfer occurred from both tested to untested and re-exposed to not re-exposed pairs. Our results highlight that RP and re-exposure can boost retention for directly tested/re-exposed event pairs and associated but untested/not re-exposed event pairs, suggesting re-exposure of integrated information can be of pedagogical value. The results also question the boundary conditions for an increase in retention for RP relative to re-exposure, highlighting the need for a better theoretical understanding of RP effects.

Homework questions designed to require higher-order cognitive skills in an undergraduate animal physiology course did not produce desirable difficulties, testing effects, or improvements in information retention

Studies show that retrieval practices such as homework assignments that are completed during the encoding phase of learning benefit knowledge acquisition and retention. In addition, desirable difficulties, which are strategies that intentionally create a greater challenge during initial learning to enhance encoding and retrieval pathways, also benefit learning long term. Our objective was to determine whether weekly homework questions intended to create desirable difficulties by requiring higher-order cognitive skills (HOCS) benefited students' long-term retention of physiology concepts compared to questions designed to require lower-order cognitive skills (LOCS). Undergraduate students in a junior-level animal physiology course were presented information during weekly laboratory periods, and then required to complete retrieval practices in the form of online homework assignments 5 d after each lab. Homework questions were formatted per Bloom's Taxonomy to require HOCS (i.e., level 4 or 5) or LOCS (i.e., level 1 or 2). Information retention was assessed the next week via performance on an in-class quiz and again at semesters' end via performance on a final practical exam. We observed no differences in performance on the in-class quiz or final practical exam between students randomly assigned to complete homework with HOCS questions compared to LOCS questions. However, students that received homework with HOCS questions had decreased (P < 0.05) performance scores on 9 out of the 11 homework assignments compared to those receiving homework with LOCS questions. These findings indicate that desirable difficulties were not created by our HOCS homework questions because students receiving these more difficult retrieval practices did not achieve equal success on them. As a result, this attempt to create variations in cognitive demand did not enhance retention of knowledge in this study.

Anatomy Terminology Performance is Improved by Combining Jigsaws, Retrieval Practice, and Cumulative Quizzing

Science courses containing English-language terminology are a common implement in "English as a foreign language" (EFL) countries across the globe. In many of these countries, licensing examinations place added significance on terminology competence by requiring health science graduates to demonstrate mastery of English-language anatomy terms. In recent years, a wealth of research has shown active learning can offer many benefits over lecture-based, didactic approaches. Despite this work, very little has been done to test the potential of active learning in improving medical terminology performance. The present study explores this potential in two human gross anatomy lecture courses in South Korea, collecting performance and survey data from 399 undergraduates over a period of four years. Jigsaws, retrieval practice, and regular cumulative quizzing were used to mitigate three learning challenges specific to the study context: high vocabulary volume, low feelings of control over learning, and difficulties with exam preparation. The results show the reforms significantly improved both performance and learning attitudes, with students overwhelmingly favoring the use of new methods over lecture when taught using a mixture of both. Given that science learning often resembles the process of learning a foreign language, this study offers broad potential for improving terminology competence across disciplines, even for non-EFL students.

Optimising word learning in post-secondary students with Developmental Language Disorder: The roles of retrieval difficulty and retrieval success during training

PURPOSE

Learning words to the level that they can be readily retrieved and produced can be challenging. The primary aim of the current study is to determine how retrieval difficulty, based on the level of cuing provided, and retrieval success during training relate to the phonological precision with which words are produced after a delay.

METHOD

We performed additional analyses on data from McGregor, Gordon, Eden, Arbisi-Kelm, & Oleson, (Encoding deficits impede word learning and memory in adults with Developmental Language Disorders. Journal of Speech, Language, and Hearing Research, 60, 2891-2905) in which post-secondary students with Developmental Language Disorder (DLD, n = 23) and typical development (n = 25) were trained on words via free and cued recall practice and tested 24-h later.

RESULTS

Training via free recall led to more precise productions after the delay than training via cued recall for both groups. Additionally, the number of successful retrievals during training positively predicted retrieval after the delay. Furthermore, the precision of participants' last production and worst production of each word were the best predictors of production precision after the delay.

CONCLUSION

To optimally support encoding and delayed retrieval, students with and without DLD should utilise free recall practice. Additionally, words should be studied until they are successfully retrieved multiple times at a high level of phonological precision to support delayed retrieval.

Neural Correlates of Long-Term Memory Enhancement Following Retrieval Practice

Retrieval practice, relative to further study, leads to long-term memory enhancement known as the “testing effect.” The neurobiological correlates of the testing effect at retrieval, when the learning benefits of testing are expressed, have not been fully characterized. Participants learned Swahili-English word-pairs and were assigned randomly to either the Study-Group or the Test-Group. After a week delay, all participants completed a cued-recall test while undergoing functional magnetic resonance imaging (fMRI). The Test-Group had superior memory for the word-pairs compared to the Study-Group. While both groups exhibited largely overlapping activations for remembered word-pairs, following an interaction analysis the Test-Group exhibited differential performance-related effects in the left putamen and left inferior parietal cortex near the supramarginal gyrus. The same analysis showed the Study-Group exhibited greater activations in the dorsal MPFC/pre-SMA and bilateral frontal operculum for remembered vs. forgotten word-pairs, whereas the Test-Group showed the opposite pattern of activation in the same regions. Thus, retrieval practice during training establishes a unique striatal-supramarginal network at retrieval that promotes enhanced memory performance. In contrast, study alone yields poorer memory but greater activations in frontal regions.

Methods for Optimizing Student Pharmacist Learning of Clinical Note Writing

Objective. To investigate the effectiveness of using problem-solving and worked examples in teaching clinical note writing to Doctor of Pharmacy students.Methods. First year student pharmacists who were recruited to participate in the study first studied a worked example on generating a clinical note from a written patient case. Participants were then randomized either to study another worked example or to practice writing a clinical note from a written patient case. Embedded in each condition was problem variability (ie, participants encountered either a similar disease state as that in the initial worked example or a different disease state). The primary outcome was the combined performance on writing two clinical notes. Secondary outcomes included quiz performance on knowledge of the components of a clinical note and ability to transfer writing skills to a novel disease state.Results. Seventy-nine students completed the study. Participants who studied a worked example followed by problem-solving (WE-PS) practice performed better than participants who studied two worked examples (WE-WE) on clinical note writing. However, there was no difference in their respective knowledge as determined by quiz performance.Conclusion. Both worked examples and problem-solving facilitated students' learning of the basic knowledge of clinical note writing. However, only problem-solving improved student pharmacists' ability to apply that knowledge. While there were significant improvements in student pharmacists' knowledge of the basics of clinical note writing, it is unclear how worked examples or problem-solving influence the clinical decision-making skills needed to write a clinical note.

Pharmacy Students' Perception of an Elective Course on Evidence-based Learning Strategies

Objective. To examine pharmacy students' perceptions of an elective course on evidence-based learning strategies.Methods. Pre- and post-course survey questionnaires were administered to students who enrolled in an elective course, to determine the learning strategies they used prior to course attendance, track their use of evidence-based learning strategies and observance of healthy lifestyle habits, and assess their perception of the course. A written assignment was given that required students to reflect on the learning outcomes that resulted from their application of evidence-based learning strategies. Mean scores on the pre- and post-course survey were analyzed using a general linear model repeated measures test.Results. The 59 students in this study predominantly used less-effective strategies (eg, re-reading and re-writing of notes) prior to taking the course. They reported increased use of evidence-based learning strategies, particularly retrieval practice and elaboration, and practice of healthy lifestyle habits (ie, enough sleep, exercise, good nutrition) after course completion. Students believed that using the above learning strategies improved their learning and memory and performance on graded assessments, among other benefits. Students had a positive perception of the course.Conclusion. The elective course was associated with increased use of effective learning strategies, adoption of healthy lifestyle practices that aid learning, and increased appreciation for evidence-based learning strategies by the students. Future studies are needed to examine actual learning outcomes and barriers to implementation of evidence-based learning techniques.

Retrieval practice facilitates learning by strengthening processing in both the anterior and posterior hippocampus

INTRODUCTION AND METHODS

A large number of behavioral studies show that retrieval practice is a powerful way of strengthening learning of new information. Repeated retrieval might support long-term retention in a quantitative sense by inducing stronger episodic representations or in a qualitative sense by contributing to the formation of more gist-like representations. Here we used fMRI to examine the brain bases related to the learning effects following retrieval practice and provide imaging support for both views by showing increased activation of anterior and posterior hippocampus regions during a delayed memory test.

RESULTS

Brain activity in the posterior hippocampus increased linearly as a function of number of successful retrievals during initial learning, whereas anterior hippocampus activity was restricted to items retrieved many but not few times during the learning phase.

CONCLUSION

Taken together, these findings indicate that retrieval practice strengthens subsequent retention via "dual action" in the anterior and posterior hippocampus, possibly reflecting coding of individual experiences as well as integration and generalization across multiple experiences. Our findings are of educational significance by providing insight into the brain bases of a learning method of applied relevance.

Where and how to learn: The interactive benefits of contextual variation, restudying, and retrieval practice for learning

Students are often advised to do all of their studying in one good place, but restudying to-be-learned material in a new context can enhance subsequent recall. We examined whether there are similar benefits for testing. In Experiment 1 (n = 106), participants studied a 36-word list and 48 hr later-when back in the same or a new context-either restudied or recalled the list without feedback. After another 48 hr, all participants free-recalled the list in a new context. Experiment 2 (n = 203) differed by having the testing-condition participants restudy the list before being tested. Across both experiments, testing in a new context reduced recall, which carried over to the final test, whereas restudying in a new context did not impair (and in Experiment 2, significantly enhanced) recall. These findings reveal critical interactions between contextual-variation and retrieval-practice effects, which we interpret as consistent with a distribution-of-memory-strengths framework.

Too much of a good thing: frequent retrieval can impair immediate new learning

Interpolated testing can reduce mind-wandering and proactive interference, and improve note-taking. However, recent research using face-name-profession triads, has also shown that interpolated testing can impair new learning (Davis, Chan, & Wilford, 2017). In the current study, we further examined the impact of switching from testing to new learning, but with objectively-true materials. The study employed a 2 (Interpolated task: Test vs. Restudy) × 3 (Task-switch frequency: 0, 11, 35) between-participants design. In two experiments, participants restudied or retrieved originally-learned flag-country associations and learned new flag-capital (Experiment 1) or flag-export (Experiment 2) associations. Task-switch frequency varied such that participants switched to new learning trial(s) after every restudy/test trial (35-switches), after every three restudy/test trials (11-switches), or did not switch at all (0-switch). The results further demonstrate that retrieving previously-learned material can impair learning of new associations by replicating Davis et al. (2017) with objectively-true materials.

Do Individual Differences in Cognition and Personality Predict Retrieval Practice Activities on MOOCs?

Online quizzes building upon the principles of retrieval practice can have beneficial effects on learning, especially long-term retention. However, it is unexplored how interindividual differences in relevant background characteristics relate to retrieval practice activities in e-learning. Thus, this study sought to probe for this research question on a massive open online course (MOOC) platform where students have the optional possibility to quiz themselves on the to-be-learned materials. Altogether 105 students were assessed with a cognitive task tapping on reasoning, and two self-assessed personality measures capturing need for cognition (NFC), and grittiness (GRIT-S). Between-group analyses revealed that cognitively high performing individuals were more likely to use the optional quizzes on the platform. Moreover, within-group analyses (n = 56) including those students using the optional quizzes on the platform showed that reasoning significantly predicted quiz performance, and quiz processing speed. NFC and GRIT-S were unrelated to each of the aforementioned retrieval practice activities.

Practicing Retrieval Facilitates Learning

How do we go about learning new information? This article reviews the importance of practicing retrieval of newly experienced information if one wants to be able to retrieve it again in the future. Specifically, practicing retrieval shortly after learning can slow the forgetting process. This benefit can be seen across various material types, and it seems prevalent in all ages and learner abilities and on all types of test. It can also be used to enhance student learning in a classroom setting. I review theoretical understanding of this phenomenon (sometimes referred to as the testing effect or as retrieval-based learning) and consider directions for future research.

Does Item Difficulty Affect the Magnitude of the Retrieval Practice Effect? An Evaluation of the Retrieval Effort Hypothesis

Retrieving information by testing improves subsequent retention more than restudy, a phenomenon known as the retrieval practice effect. According to the retrieval effort hypothesis (REH), difficult items require more retrieval effort than easier items and, consequently, should benefit more from retrieval practice. In two experiments, we tested this prediction. Participants learned sets of easy and difficult Swahili-Portuguese word pairs (study phase) and repeatedly restudied half of these items and repeatedly retrieval practiced the other half (practice phase). Forty-eight hours later, they took a cued-recall test (final test phase). In both experiments, we replicated both the retrieval practice and the item difficulty effects. In Experiment 1 (N = 51), we found a greater retrieval practice effect for easy items, MDifference = .26, SD = .17, than for difficult items, MDifference = .19, SD = .19, t(50) = 2.01, p = .05, d = 0.28. In Experiment 2 (N = 28), we found a nonsignificant trend-F(1, 27) = 2.86, p = .10, $$ {\upeta}_{\mathrm{p}}^2 $$ = .10-toward a greater retrieval practice effect for difficult items, MDifference = .28, SD = .22, than for easy items, MDifference = .18, SD = .21. This was especially true for individuals who benefit from retrieval practice (difficult: MDifference = .32, SD = .18; easy: MDifference = .20, SD = .20), t(24) = -2.08, p = .05, d = -0.42. The results provide no clear evidence for the REH and are discussed in relation to current accounts of the retrieval practice effect.

Effects of repeated retrieval on keyword mediator use: shifting to direct retrieval predicts better learning outcomes

Keyword mediators are an effective memory technique to encode novel vocabulary: learners link a novel word form to its meaning with a mental image that includes a keyword that resembles the word form (e.g., nyanya = tomato; keyword mnemonic: the ninja chops the tomato in half). Prior research suggests that such mediated form-meaning associations become less dependent on keywords after retrieval practice. The present study investigated if retrieval-induced decreases in mediator use predict word retention. Thirty participants learned novel vocabulary using experimenter-provided keywords and repeatedly retrieved the words from memory while thinking aloud. As expected, keyword use decreased with practice: learners stopped mentioning keywords for 21.6% of the words (on average after 8.27 retrievals). Shifting to direct, unmediated retrieval predicted higher form and meaning recall on a retention test after 6-8 days. Continuing retrieval practice until a shift has occurred to direct retrieval thus seems beneficial for retention.

The refinement of flipped teaching implementation to include retrieval practice

There has been growing evidence that flipped teaching (FT) can increase student engagement. Traditional lecture-based teaching (TT) method was compared with FT and FT combined with retrieval practice (FTR) in a 400-level Exercise Physiology course over eight semesters. In the FT format, lecture content was assigned for students to prepare before class along with an online quiz. During class, the assigned content and quiz questions were reviewed, and a team-based learning (TBL) activity was conducted. Students found FT implementation three times a week (FT3) to be overwhelming, which led to reconfiguration of the FT design to minimize the quiz and TBL sessions to one per week. Subsequently, FT was combined with retrieval exercises (FTR), which involved recalling information, thus promoting retention. The students in the FTR format were given weekly quizzes in class, where no notes were allowed, which affected their quiz grade negatively compared with FT (P < 0.0001). Again, no resources were permitted during FTR's TBL sessions. When exam scores were compared with TT, student performance was significantly greater (P < 0.001) with the FT and FTR methods, suggesting these methods are superior to TT. While both male and female students benefited from FT and FTR methods compared with TT (P = 0.0008), male students benefited the most ((P = 0.0001). Similarly, when the exam scores were organized into upper and lower halves, both groups benefited from FT and FTR (P < 0.0001) approaches. In conclusion, both FT and FTR methods benefit students more compared with TT, and male students are impacted the most.

Episodic context reinstatement promotes memory retention in older but not younger elementary schoolchildren

Previous studies have shown that reinstatement of spatial and temporal background information during learning can promote memory retention in adults. However, the effect in children is unclear. In order to explore the effect of episodic context reinstatement on the memory retention of different age groups, first-grade students, third-grade students, and third-year college students studied two word lists. When the words were presented mixed together, the participants were told to either restudy the words under intentional learning conditions or make list discrimination judgements by indicating the list from which each word had originated. Results revealed that the retrieval practice based on the episodic context reinstatement paradigm showed a phased development trend in the participants compared to restudy. Episodic context reinstatement only promoted memory retention in the third-grade children and college students, but not in the first-grade children. During the early elementary school years, children do not have relatively mature episodic memory ability and cannot output memories according to context clues. Our finding suggests important guidance for the age-appropriate use of tests as instructional tools in basic education. Statement of contribution What is already known on this subject? One recent theory of retrieval-based learning is the episodic context account; it promotes memory retention by reinstate the context of a prior learning episode. Previous studies have confirmed in the adults that the episodic context reinstatement was the main reason for retrieval practice to promote memory retention through the list discrimination tasks What does this study add? This study revealed that the retrieval practice based on the episodic context reinstatement paradigm showed a phased development trend in the participants. Episodic context reinstatement only promoted memory retention in the third-grade children and college students, but not in the first-grade children, and the results support the episodic context assumption, namely that episodic context reinstatement is the key factor in memory retention. The results of this study can explain why most prior work has observed the effect of retrieval practice in the groups above grade three.

Retrieval Practice Improves Recollection-Based Memory Over a Seven-Day Period in Younger and Older Adults

Retrieving information improves subsequent memory performance more strongly than restudying. However, despite recent evidence for this retrieval practice effect (RPE), the temporal dynamics, age-related changes, and their possible interactions remain unclear. Therefore, we tested 45 young (18–30 years) and 41 older (50 + years) participants with a previously established RP paradigm. Specifically, subjects retrieved and restudied scene images on Day 1; subsequently, their recognition memory for the presented items was tested on the same day of learning and 7 days later using a remember/know paradigm. As main findings we can show that both young and older adults benefited from RP, however, the older participants benefited to a lesser extent. Importantly, the RPE was present immediately after learning on Day 1 and 7 days later, with no significant differences between time points. Finally, RP improved recollection rates more strongly than familiarity rates, independent of age and retrieval interval. Together, our results provide evidence that the RPE is reduced but still existing in older adults, it is stable over a period of seven days and relies more strongly on hippocampus-based recollection.

Student-led Recaps and Retrieval Practice: A Simple Classroom Activity Emphasizing Effective Learning Strategies

It is imperative that college and university faculty members continue to collaborate to develop and assess innovative teaching methods that effectively encourage learning for all undergraduates, particularly in STEM. Here we describe a simple student-led classroom technique, recap and retrieval practice (R&RP), that we, as two instructors at different institutions, collaboratively implemented in three upper-level STEM courses. R&RP sessions are short, student-led reviews of previous course material that feature student voices prominently at the start of every class period. R&RP sessions require a small team of students to prepare and deliver a review of prior course content via active retrieval practice formats, which are well known to be particularly effective learning tools. These R&RP assignments were also designed to emphasize additional evidence-based learning practices (concrete examples, dual coding, elaboration, interleaving, and spaced practice). Our analysis of undergraduate student experiences both in leading and participating in R&RPs indicates that overall R&RP sessions were well-received, active learning strategies that our students indicated fostered their learning. As instructors, we found R&RPs an effective and efficient strategy to encourage class participation, assess class participation, and emphasize student voices in our classrooms. Moreover, we found that collaboratively deploying a learning activity allowed us to observe the impact of a specific pedagogical activity in varied instructional settings and enhanced our professional development as educators.

Retrieval practice improves memory in patients with schizophrenia: new perspectives for cognitive remediation

BACKGROUND

Schizophrenia is associated with severe cognitive deficits, particularly episodic memory deficits, that interfere with patients' socio-professional functioning. Retrieval practice (also known as testing effect) is a well-established episodic memory strategy that involves taking an initial memory test on a previously learned material. Testing later produces robust long-term memory improvements in comparison to the restudy of the same material both in healthy subjects and in some clinical populations with memory deficits. While retrieval practice might represent a relevant cognitive remediation strategy in patients with schizophrenia, studies using optimal procedures to explore the benefits of retrieval practice in this population are still lacking. Therefore, the purpose of our study was to investigate the benefits of retrieval practice in patients with schizophrenia.

METHODS

Nineteen stabilised outpatients with schizophrenia (DSM-5 criteria) and 20 healthy controls first studied a list of 60 word-pairs (30 pairs with weak semantic association and 30 non associated pairs). Half the pairs were studied again (restudy condition), while only the first word of the pair was presented and the subject had to recall the second word for the other half (retrieval practice condition). The final memory test consisted in a cued-recall which took place 2 days later. Statistical analyses were performed using Bayesian methods.

RESULTS

Cognitive performances were globally altered in patients. However, in both groups, memory performances for word-pairs were significantly better after retrieval practice than after restudy (56.1% vs 35.7%, respectively, Pr(RP > RS) > 0.999), and when a weak semantic association was present (64.7% vs 27.1%, respectively; Pr(weak > no) > 0.999). Moreover, the positive effect of RP was observed in all patients but one.

CONCLUSIONS

Our study is the first to demonstrate that retrieval practice efficiently improves episodic memory in comparison to restudy in patients with schizophrenia. This learning strategy should therefore be considered as a useful tool for cognitive remediation programs. In this perspective, future studies might explore retrieval practice using more ecological material.

The Twelve Cranial Nerves of Christmas: Mnemonics, Rhyme, and Anatomy - Seeing the Lighter Side

Anatomy, has in history, been linked to helpful ways to remember structures, branches of nerves, structures passing through foramina, etc. Scalp is even a mnemonic in itself (Skin, Connective tissue, Aponeurosis, Loose areolar tissue, Pericranium). There has been concern by some educators that using mnemonics or rhymes promotes a surface approach to learning and is unhelpful in establishing long-term and meaningful deep learning. This article argues that mnemonics and rhyme can be used, in the appropriate way, at the right time, by students as an important learning strategy. That strategy can help lay a foundation of knowledge to be developed and later built upon, or simply recall information more easily. Mnemonics, like all information that is to be recalled, is consolidated by rehearsal. In examining the neuroanatomy of learning theories, it is therefore possible to suggest that when students begin to learn an area of anatomy, such as the cranial nerves, using a mnemonic or rhyme, it can help students remember the names and facilitate the engagement of the working memory processes assisting the student to build a construct for subsequent deeper layers of knowledge. Modern approaches to anatomy education involve a myriad of learning opportunities, but educators must assess the value of each one before recommending them to students. It appears that using mnemonics and rhyme is as valid today as it has been for centuries.

Feedback at Test Can Reverse the Retrieval-Effort Effect

The testing effect refers to the finding that retrieving previously encoded material typically improves subsequent recall performance more on a later test than does restudying that material. Storm et al. (2014) demonstrated, however, that when feedback is provided on such a later test the testing advantage then turns to a restudying advantage on subsequent tests. The goal of the present research was to examine whether there is a similar consequence of feedback when the difficulty of initial retrieval practice is modulated. Replicating prior research, we found that on an initial delayed test, recall of to-be-learned items was better following difficult than easy practice. Critically, however, providing immediate feedback on an initial delayed test reversed this pattern. Our findings are consistent with a distribution-based interpretation of how feedback at test modifies recall performance.
