A hybrid flipped-classroom approach for online teaching of biochemistry in developing countries during Covid-19 crisis

Comparison of the teaching clinical biochemistry in face-to-face and the flex-flipped classroom to medical and dental students: a quasi-experimental study from IRAN

INTRODUCTION

Biochemistry is one of the main courses of basic sciences in the medical curriculum, along with other difficult subjects that are difficult to learn. The emergence of new technologies has made it possible to test new methods such as e-Learning. In this study, we compared two methods of Flex-Flipped Classroom (FFC) and face-to-face.

METHOD

A quasi-experimental research was done which involved both medical and dental students studying the clinical biochemistry course in the joint semester in 2019. A total of 100 medical students were trained in biochemistry through face-to-face teaching, and 60 dental students were trained in the same course through the FFC model. Three researcher-made tools were used to compare the two groups to assess the student's satisfaction, scores, and self-evaluation. The content validity of the tools was checked using the opinions of 10 experts through the CVI index. The results were analyzed using one-sample t-tests, independent t-tests, and ANOVA.

RESULTS

Both groups scored significantly more than the cut-off-point (Mean > 3.5) in their average scores of the total and sub-components of the self-evaluation questionnaire (P < 0.05). Face-to-face teaching was viewed more favorably than the FFC teaching except for considering the flexibility (4.14 ± 1.55), but the difference was not significant (P > 0.05). The students' knowledge score in the FFC was slightly higher than that in the face-to-face method, but this difference was not significant(P = 0.758).

CONCLUSION

Both face-to-face and FFC methods were effective according to the students, but the level of satisfaction with the face-to-face method was higher. It seems that teacher-student interaction is an important factor in students' preferences. However, the students preferred the flexibility of multimedia. It seems necessary to use the advantages of each method in a model appropriate to the students' conditions and available facilities.

Use of mobile learning applications as an innovative method for the teaching of biochemistry

BACKGROUND

Traditional teaching methods of biochemistry provide effective tools for knowledge transmission, but are considered less engaging with students. Smartphone applications may provide suitable alternatives to compensate for the shortcomings of traditional teaching methods.

PURPOSE

This study aimed to assess the effectiveness of smartphone applications as a complementary method for learning biochemistry.

METHODOLOGY

A total of 32 students, from the College of Applied Medical Sciences, University of Bisha, Saudi Arabia, were recruited. Students used available mobile applications, and their performance was monitored through assignments, presentations, practical evaluations, and pre- and post-tests. A self-administered structured questionnaire was used to survey the students' perceptions. It was validated by students enrolled at the College of Applied Medical Science, interns, and medical educators. It was checked for item appropriateness and comprehensiveness using face and content validity.

RESULTS

Around 75% of the students found the mobile applications useful in learning biochemistry, 50% believed that they were easy to use and 100% believed that the breadth of the knowledge presented by these applications was comprehensive. The pedagogical effect of the use of mobile applications in learning biochemistry showed statistically significant differences in student performances post-use and pre-use of mobile applications with P values of 0.000, 0.028, 0.023, and 0.000 for tests, assignments, practical evaluation, and presentations, respectively.

CONCLUSION

Students have a positive perception of the use of mobile applications, as it has significantly improved their academic performance in biochemistry.

Graduate and postgraduate educational challenges during the COVID-19 pandemic period: its impact and innovations-a scoping review

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic has transformed the global view of education, including graduate and postgraduate education making the development of an alternative approach in times of social isolation an academic imperative. The present review aims to investigate the challenges experienced among undergraduate and postgraduate education and the strategies adopted to address these challenges during the pandemic.

METHOD

The preferred reporting items for the systematic review and meta-analyses extension for Scoping Reviews (PRISMA-ScR) were followed. The aim was to include journal articles published in the English language that discussed the influence of the pandemic on educational processes and applied innovative approaches as a solution to educational challenges. From January to August 2020, PubMed, EMBASE, and Google Scholar were searched for articles, yielding 10,019 articles. Two groups of authors examined the retrieved articles separately to avoid any risk of bias. The title and abstract of the articles were used for scrutiny, followed by full-text screening based on the established inclusion and exclusion criteria. The facts and findings of the studies were also discussed based on per capita income, literacy rate, and Internet accessibility.

RESULTS

Thirty of the obtained articles were included in the study. The selected articles were from North and South/Latin America, Asia & Pacific, South Africa, and Europe regions. Nineteen of the selected articles dealt with undergraduate education, ten with postgraduate, and one with both groups. The affordability of digital devices and the availability of Internet services were the major challenges for low- and middle-income economies. The ZOOM platform has been adopted by more than 90% of the education systems.

CONCLUSION

Means of communication, including visual media, digitized content, and other web-based platforms, have been recognized as efficient learning and training tools, but have not been fully accessible for mass application and use due to the lack of availability of resources, their cost, and insufficient training among the users. In light of this review, it is suggested that harmonized and collaborative efforts should be made to develop cost-effective and user-friendly tools to overcome the current challenges and prevent future educational crises.

The Impact of COVID-19 Pandemic on Flipped Classroom for EFL Courses: A Systematic Literature Review

The outbreak of the COVID-19 pandemic has had a significant impact on education. The closure of schools and the cessation of face-to-face classrooms have affected schools and students worldwide. The current need is to transform the traditional classroom to adapt to the new social and educational background. The flipped classroom is usually defined as a strategy to subvert the conventional academic environment; that is, the information transmission part of the traditional face-to-face lecture is removed from the classroom time for online self-learning. The flipped classroom is a highly flexible classroom mode, which has brought significant changes to education. Therefore, this study aims to examine the studies' research trends, advantages, and challenges concerning the flipped classroom for EFL courses during the COVID-19 epidemic. For this purpose, databases including the web of Science (WOS) and Scopus were reviewed, and 15 articles were analyzed. A systematic review was used as the research methodology. The study's findings revealed the effectiveness of flipped classrooms for EFL courses during the pandemic. Based on the review, this paper puts forward suggestions for future research and points out the future development direction.

Comparison of academic performance of medical undergraduate students between routine class room teaching and online assisted teaching in biochemistry during COVID pandemic

The new curriculum of competency based medical education (CBME) implemented for phase1 medical undergraduates could not go on to completion due to the sudden outbreak of the COVID-19 pandemic. The educational institutions therefore resorted to online teaching modalities over conventional class room teachings. Hence this study aimed to compare the academic performance of students between routine classroom teaching and online assisted teaching with assignments.94 phase 1 MBBS students admitted in the year 2019-2020 was divided into low (<50%), medium (51%-70%) and high performers (71%-100%) based on the average marks in the initial formative assessments. Academic performance of students in three types of teaching modalities namely classroom teaching (CRT), classroom teaching with assignment (CRA), and online assisted teaching (OAT) were compared using ANOVA. Wilcoxon signed ranks test was used to find the difference in marks between CRT and CRA which was calculated as gain 1 and that between OAT and CRT is gain 2. Out of 94 students, 19 were low performers, 53 were medium performers and 22 were high performers when grouped at baseline. All these groups performed significantly well with OAT compared to CRT and CRA. The overall performance of girls was found to be significantly higher. There was no significant difference between Gain 1 and Gain 2. All group of students scored high in assessments following online teaching compared to conventional classroom teaching. The gain of online teaching did not outweigh the conventional teaching methods implying that face to face lectures is still an effective teaching modality.

Case study: Co-creating a flipped feed-in approach to a virtual biochemistry lab assessment: increasing student achievement and engagement in a large, diverse cohort

More inclusive, authentic assessments are required to address awarding gaps and to ensure that bioscience students can apply their knowledge to relevant work-based scenarios. In this case report, we present a co-created approach to designing a more inclusive, virtual biochemistry lab assessment for a diverse cohort of ∼270 first-year students. The assignment was to write up an inclusive clinical case study as a one-page journal article. A flipped classroom approach taught the relevant skills, along with simulated labs from Learning Science Ltd. Student Lecturers co-created the assessment, including the marking rubric and the unexemplars. We replaced traditional feedback with a flipped, feed-in approach where students were able to engage in a formative assessment with peer marking and unexemplars. Whilst the summative assessment was marked anonymously, a dialogue-based approach was employed, where students could request personalised audio feed-forward from the tutor. The high pass rate (97%) and student satisfaction score (88%) suggest that this approach is an effective way to challenge, engage and support a large, diverse cohort of students. First-year students who participated in the flipped feed-in experience obtained a significantly higher summative mark (56.7% cf. 50.9%) than those who did not. Interestingly, students in receipt of learning adjustments scored higher marks on average in the summative assessment (59.3% cf. 54.3%), suggesting that we have reversed the disability-based attainment gap. Further investigation into whether a co-created, flipped feed-in approach can reduce attainment gaps based on ethnicity, gender and age is warranted.

Re-thinking cheat-proof and supervision-free exams: A perspective in view of Covid-19 situation in developing economies

The emergence of the global pandemic, SARS-CoV-2 has posed several challenges to education across the globe and led to the emergence and progression of newer methods of teaching and assessment. While online teaching has been quickly adopted and implemented across the globe, exams and assessment remain poorly managed both at an elementary and higher level. The practice of promoting students without an equivalent assessment or poor methods of online examinations systems poses a future difficulty in employability assessment and academic equivalence. Here we propose some suggestive measures especially for developing economies with a lack of adequate technology and insufficiently sensitized trainers for online assessment to avert the difficulties due to faulty examination schemes in pandemic situations with prolonged lockdowns.

Adaptive learning: Helpful to the flipped classroom in the online environment of COVID?

Flipped instruction in an undergraduate numerical methods course in the online, remote environment during the COVID-19 pandemic was conducted with and without the use of adaptive-learning lessons for pre-class preparation. This comparison was made to explore potential differences with and without adaptive software relative to exam and concept inventory performance and student perceptions of the classroom environment, learning and motivation, and benefits and drawbacks. Student perceptions were gathered via the College and University Classroom Environment Inventory (CUCEI) and a survey designed to capture feedback specific to flipped instruction. The analysis was made possible by a current NSF grant to study adaptive learning in the flipped classroom at three universities and extensive prior research with the flipped classroom and adaptive learning by the authors. Results gathered in the online flipped classroom with adaptive learning suggested positive changes in the following: classroom environmental perceptions, preference for flipped instruction, perceived responsibility imposed, motivation for independent learning, and perceived learning. Furthermore, based on an open-ended question, there was a significant decrease in the proportion of students who experienced load, burden, or stressors in the online flipped classroom when adaptive learning was available versus not. Multiple-choice exam and concept-inventory results were slightly higher with adaptive lessons (although not significantly so), with the most promising results occurring for Pell grant recipients. The emerging medical education literature has suggested that adaptive learning and flipped instruction will be key to post-pandemic education. The present article begins advocacy for adaptive learning with flipped instruction in engineering education.

The construction and application of a blended teaching model under the strategic background of healthy China

In order to cultivate the ability of independent learning and lifelong learning of medical students, improve the ability of students to analyze and solve problems, improve the competence of medical talents and cultivate high-level and innovative talents, we have constructed the blended teaching model of "Clinical Case Investigation-Online Open Course Learning-Classroom PBL Seminar-After-Class Health Education". At the same time, an ability-oriented performance evaluation system improved the teaching quality feedback system has also established. This article introduces the construction and application of the blended teaching model, as well as the problems it faces, provides a theoretical basis for the optimization and improvement of this model. It also provides a model theory and practical basis for creating a blended online and offline "golden course" for the professional courses of medical laboratory technology.

Virtual flipped teaching during the COVID-19 pandemic

The COVID-19 pandemic forced teaching to be shifted to an online platform. Since the flipped teaching (FT) model has been shown to engage students through active learning strategies and adapt both synchronous and asynchronous components, it was a convenient choice for educators familiar with this instructional method. This study tested the effectiveness of a virtual FT method during the pandemic in a graduate-level physiology course. Besides assessing knowledge gained in the virtual FT format, student surveys were used to measure student perception of their adjustment to the new FT format, their confidence in completing the course successfully, and the usefulness of assessments and assignments in the remote FT. Students reported that they adjusted well to the remote FT method (P < 0.001), and their confidence in completing the course in this teaching mode successfully improved from the beginning to the end of the semester (P < 0.05). Students expressed a positive response to the synchronous computerized exams (90.32%) and the formative group (93.51%) and individual (80.65%) assessments. Both collaborative activities (93.55%) and in-class discussions (96.77%) were found to be effective. The course evaluations and the overall semester scores were comparable to the previous semesters of face-to-face FT. Overall, students' perceptions and performance suggested that they embraced the virtual FT method and the tested teaching method maintained the same strong outcome as before. Thus, this study presents a promising new instructional method in the teaching of future physiology courses.

Flipped Learning in Engineering Modules Is More Than Watching Videos: The Development of Personal and Professional Skills

The Accreditation Board for Engineering and Technology (ABET) has highlighted two key outcomes for students of all accredited engineering programs: the ability to communicate effectively with a range of audiences and the capacity to acquire and apply new knowledge as needed, using appropriate learning strategies. Likewise, in recent years, written exams, assignments, and oral presentations show transmission-skill deficiencies among engineering students. Flipped teaching serves to boost students to meet these outcomes and other competencies: comprehension reading, communication skills, character building, collaborative work, critical thinking, or creativity. So, flipped learning is more than watching videos. This research proposes two evidence-based transferable learning strategies built on a flipped-teaching model and was applied by the authors in engineering courses during the second year of the global pandemic caused by COVID-19: problem-based learning and teamwork assignments. The study comprised two phases. First, a systematic review of reports, writings, and exams delivered by students. It included some video-watching analytics to detect misuse. In the second stage, the authors ascertained trends of these outcomes. Student perceptions and other achievement indicators illustrate the possibilities for encouraging learners to achieve transmission, communication, and literacy outcomes. Results indicate that these learner-centered approaches may help students learn better, comprehend, apply, and transmit knowledge. But they require an institutional commitment to implementing proactive instruction techniques that emphasize the importance of student communication skills.
