Are virtual physiology laboratories effective for student learning? A systematic review

Virtual rat web: A versatile simulation tool for pharmacology education in a variety of settings

Education and outreach activities are crucial elements in the popularization of various scientific fields, including pharmacology. Simulation-based learning can impart scientific knowledge and stimulate critical thinking in both children and adults. Here, we developed a standalone web-based simulation tool, Virtual Rat Web (VRW), to promote a greater understanding of pharmacology and assessed its usefulness in educational and outreach settings. VRW is a web-based application based on the source code of RatCVS, a program developed by Dr. John Dempster (University of Strathclyde) to model cardiovascular pharmacology. We evaluated VRW as part of a model pharmacology class taught to high-school students, and elementary/junior high-school students or older students attending university outreach classes. The two older student groups were given a 60-min class consisting of a brief introduction to drug effects on the cardiovascular system, training on the use of VRW, and a hands-on exercise using VRW to identify noradrenaline and acetylcholine from a panel of anonymized drugs based on their dose-response patterns. Most students correctly identified the effects of noradrenaline and acetylcholine and found VRW to be a more useful learning tool than a passive lecture. The elementary/junior high-school students received a 120-min class combining real-time visualization of the effects of adrenaline and propranolol on the heart rate of zebrafish larvae and hands-on use of VRW to confirm the in vivo observations. This cohort found the strength of VRW in understanding the dose-response. These findings suggest that VRW may be a versatile tool for pharmacology education in various settings.

Virtual laboratories complement but should not replace face-to-face classes: perceptions of life science students at Dundalk Institute of Technology, Ireland

Virtual laboratories (VLs) enable students to experiment, analyze data, or interact with digital content in a nonphysical space. VLs include simulations, electronic notebooks, videos, and augmented reality. As part of the "VL Project," comprising five academic institutions in Ireland, we sought to determine how VLs might enhance practical learning in undergraduate life science students at Dundalk Institute of Technology (DkIT). From 2021 to 2024, we exposed students to VLs in multiple degrees (e.g., BSc Bioscience, BSc Pharmaceutical Science, BSc Biopharmaceutical Science). We focused on Labster simulations and Lab Archives electronic notebooks. Over 600 students performed VLs in 14 modules from first to fourth year (e.g., Biotechnology, Immunology, Bioanalytical Science). We surveyed students before and after using VLs and conducted focus groups to evaluate emergent themes in depth. Among respondents (n = 263), the most beneficial component of laboratory experiences, as indicated by 58% of students was experimental work (as opposed to prepractical talks or postlaboratory assessments). Ninety percent of students agreed with the statement: "VLs enhanced my level of confidence with experimental science." Seventy-five percent of students stated VLs should only be used to complement face-to-face (F-2-F) teaching. Thematic focus group analysis revealed students valued VLs as prelaboratory tools, allowing repeated engagement with, and troubleshooting of experiments in a safe, nontime-limited manner. In conclusion, students reinforced they valued hands-on experience, in-person instructor guidance, and real-world demonstration for experimental work. VLs can complement but should not replace F-2-F laboratory experiences in undergraduate life sciences.NEW & NOTEWORTHY This study represents the largest and most systematic analysis of student perceptions of life science virtual laboratories conducted in Ireland. Our findings provide student-centered feedback on the potential benefits and challenges of using virtual laboratories to enhance life science learning and have wide implications for how these resources might be best utilized in other institutions in the future.

Identifying Research Priorities in Digital Education for Health Care: Umbrella Review and Modified Delphi Method Study

BACKGROUND

In recent years, the use of digital technology in the education of health care professionals has surged, partly driven by the COVID-19 pandemic. However, there is still a need for focused research to establish evidence of its effectiveness.

OBJECTIVE

This study aimed to define the gaps in the evidence for the efficacy of digital education and to identify priority areas where future research has the potential to contribute to our understanding and use of digital education.

METHODS

We used a 2-stage approach to identify research priorities. First, an umbrella review of the recent literature (published between 2020 and 2023) was performed to identify and build on existing work. Second, expert consensus on the priority research questions was obtained using a modified Delphi method.

RESULTS

A total of 8857 potentially relevant papers were identified. Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology, we included 217 papers for full review. All papers were either systematic reviews or meta-analyses. A total of 151 research recommendations were extracted from the 217 papers. These were analyzed, recategorized, and consolidated to create a final list of 63 questions. From these, a modified Delphi process with 42 experts was used to produce the top-five rated research priorities: (1) How do we measure the learning transfer from digital education into the clinical setting? (2) How can we optimize the use of artificial intelligence, machine learning, and deep learning to facilitate education and training? (3) What are the methodological requirements for high-quality rigorous studies assessing the outcomes of digital health education? (4) How does the design of digital education interventions (eg, format and modality) in health professionals' education and training curriculum affect learning outcomes? and (5) How should learning outcomes in the field of health professions' digital education be defined and standardized?

CONCLUSIONS

This review provides a prioritized list of research gaps in digital education in health care, which will be of use to researchers, educators, education providers, and funding agencies. Additional proposals are discussed regarding the next steps needed to advance this agenda, aiming to promote meaningful and practical research on the use of digital technologies and drive excellence in health care education.

Community college student perceptions of digital anatomy models as a curricular resource

Digital model platforms and applications are common in anatomy education and continue to grow in number, which suggests that educators and students find use for these tools despite the lack of widely accepted best practices. Consequently, it is a challenge for educators to mindfully integrate digital models into curriculum. This short-term, longitudinal study investigated the effects of integrating a monoscopic digital model as a teaching tool during lectures on reproductive and endocrine anatomy as an intervention in a community college human anatomy and physiology course. Student use and perceptions of digital models were analyzed for correlation with the nature of the course content and the intervention (n = 92). Academic content significantly affected self-reported student use (p < 0.001) as well as student perceived usefulness of the model (p = 0.02). These findings support the conjecture that digital anatomy models may be better for achieving certain specific learning goals opposed to all learning goals. Integration of digital models as an instructional method did not consistently influence student behavior but it made a difference in participant ability to recognize this technology outside of the lecture. Overall, participants had a positive perception of digital models, although they were not perceived as more important than all other curricular resources. Inclusion of monoscopic digital models for teaching anatomy should be considered by educators since teaching with digital models can demonstrate strengths and weaknesses for students within the context the of learning objectives, assisting students to make more informed decisions about effective learning tools.

Assigned group work is associated with increased student motivation and perceptions of belonging in an asynchronous online physiology laboratory course

With the rise of online instruction, a better understanding of the factors that contribute to belonging and motivation in these contexts is essential to creating optimal learning environments. Although group work is known to be beneficial to student success, few studies have investigated its role in the context of asynchronous online courses. The present study addresses this gap through a survey of 146 undergraduate students in an asynchronous online physiology lab over two semesters, one with required group work and one without group work. Students were surveyed to evaluate the influence of group work on their motivation and sense of belonging, as well as their perceptions of inclusive and exclusive features of the course. Students assigned to groups had a higher sense of belonging (P = 0.006) and beliefs about their competence (P = 0.002) and perceived lower effort and psychological costs associated with the course (P = 0.04 and 0.04, respectively) compared to students not assigned to groups. Students assigned to groups reported that peer interactions made them feel included in the course (70% of coded responses) while those not assigned to groups valued instructor interactions (51% of coded responses) as inclusive. Negative peer interactions were commonly reported as exclusive by students assigned to groups (28% of coded responses) while a lack of peer interactions (23% of coded responses) made students not assigned to groups feel excluded. These data indicate that assigning groups in asynchronous online courses is an effective way to increase student motivation and perceptions of belonging.NEW & NOTEWORTHY This study explores the effect of assigned group work in an asynchronous online physiology laboratory course on student motivation and belonging. Students' perceptions of belonging and competence-related beliefs were higher, and effort and psychological costs were lower, when assigned to groups compared to students not assigned to groups. Students assigned to groups noted peer interactions as the most inclusive aspect of the course, whereas instructor interactions were noted as inclusive by those not assigned group work.

Diversifying laboratory assessment modes broadens engagement with practical competencies in life science students

Laboratory practicals in life science subjects are traditionally assessed by written reports that reflect disciplinary norms for documenting experimental activities. However, the exclusive application of this assessment has the potential to engage only a narrow range of competencies. In this study, we explored how multiple modes of laboratory assessment might affect student perceptions of learned skills in a life science module. We hypothesized that while a mixture of assessments may not impact student summative performance, it might positively influence student perceptions of different skills that varied assessments allowed them to practice. This was informed by universal design for learning and teaching for understanding frameworks. In our study, in a third-year Bioscience program, written reports were complemented with group presentations and online quizzes via Moodle. Anonymous surveys evaluated whether this expanded portfolio of assessments promoted awareness of, and engagement with, a broader range of practical competencies. Aspects that influenced student preferences in assessment mode included time limitations, time investment, ability to practice new skills, links with lecture material, and experience of assessment anxiety. In particular, presentations were highlighted as promoting collaboration and communication and the quiz as an effective means of diversifying assessment schedules. A key takeaway from students was that while reports were important, an overreliance on them was detrimental. This study suggests that undergraduate life science students can benefit significantly from a holistic assessment strategy that complements reports with performance-based approaches that incorporate broader competencies and allow for greater student engagement and expression in undergraduate modules.NEW & NOTEWORTHY This study suggests that undergraduate life science students can benefit significantly from a holistic assessment strategy that complements reports with performance-based approaches that incorporate broader competencies and allow for greater student engagement and expression in undergraduate modules.

Co-created in vivo pharmacology practical classes using the novel organism Lumbriculus variegatus

Co-creation within higher education emphasizes learner empowerment to promote collaboration between the students and staff, enabling students to become active participants in their learning process and the construction of resources with academic staff. Concurrently, a diminishing number of higher education institutions offer in vivo practical classes, resulting in an in vivo skills shortage. To address this, and to actively engage students in their own learning, we describe the co-creation of a student-led drug trial using Lumbriculus variegatus. Under blinded conditions, final-year undergraduate biomedical science students, under the tutelage of academic staff and fellow students, were involved in the co-creation of an in vivo practical class to determine the effects of histamine and histamine receptor inverse agonists mepyramine and loratadine. Throughout this process, undergraduate- and masters-level students played key roles in every aspect of practical delivery and data analysis. Herein, students demonstrated the test compounds, both in isolation and in combination, resulted in reduced stereotypical movements of L. variegatus (p < .05, n ≥ 6). 15% of students in the class responded to a feedback survey (n = 8) after the class. Students reported the class provided "real life" insights into in vivo research and enabled the development of hands-on skills which would be useful in applying in their future careers. All students reported that they enjoyed the class with 25% (n = 2) reporting concerns about animal use in research, enabling useful discussions about animals in research. Moreover, these student-led in vivo trials add to the pharmacological knowledge of L. variegatus promoting education-led research.

Reducing cognitive load during video lectures in physiology with eye movement modeling and pauses: a randomized controlled study

Lectures constitute a basic component of physiology instruction in scientific and healthcare curricula. Technological progress has allowed a switch from face to face to video lectures, yet there is no evidence of video efficacy in physiology. Because videos increase the cognitive load during a learning task, identifying tools that decrease students' cognitive load during video lectures is critical. Segmenting videos with pauses and inducing joint attention with eye movement modeling examples (EMME) could reduce the cognitive load and improve second-year medical students' learning in physiology video lectures. Second-year medical students were randomized into four groups [EMME + pauses (EMME + P), EMME without pause`s (EMME-NoP), pauses only (NoEMME + P), and no EMME and no pause (NoEMME-NoP)], took pretest quizzes, watched a renal physiology video lecture, and answered a cognitive load questionnaire and posttest quizzes on the Moodle learning management system. Student prior knowledge was assessed by a pretest, and learning gains were assessed by the difference between posttest and pretest scores. One hundred ninety-five students completed the experiment. Pauses improved learning gains (P < 0.01) but not EMME (P = 0.11). Student prior knowledge has several interactions with other variables: low-prior knowledge students obtained better learning gains (P < 0.001) and high-prior knowledge students had lower learning gains with EMME (P < 0.05). Our study shows the potential role of tools designed to reduce students' cognitive load during a renal physiology video lecture and the critical need for empirical validation of pedagogical solutions that are adapted to the specificities of physiology lectures.

Virtual immunology: an educational software to encourage antigen-antibody interaction learning

Immunology is a knowledge area of paramount importance in life sciences and health care professional education with diverse applications, as well as for a general public understanding of issues related to vaccination. However, many concepts are complex and difficult to understand based only on conventional classes or static images. The use of tools, such as educational software, may enhance the learning of dynamic molecular phenomena that occur in our bodies. Virtual Immunology is a software that aims to facilitate the learning of certain complex immunology concepts. Herein, we present the "Antigen-antibody interactions" module that was used and evaluated by 127 students and 3 teachers from medical schools from 2 universities, 1 public and 1 private, both in the state of Rio de Janeiro, Brazil. The pretest/posttest research design was used to assess student learning in a randomized sample. To evaluate user perceptions concerning software quality, 14 statements were analyzed using a Likert scale. Results indicate suitable evaluations from both students and teachers concerning the "Antigen-antibody module" as an auxiliary tool in immunology teaching. The software was well rated as an educational resource since it allows dynamically viewing immunological phenomena. In addition, its ease of use and immunological process visualization were the best-evaluated parameters by the students, who recommended this software module as an auxiliary learning tool. The use of the evaluated software may motivate students and aid in the understanding of immunology-related concepts, becoming a complementary tool that may enhance the teaching-learning process.

An analysis of anatomy education before and during Covid-19: August-December 2020

Coronavirus disease-2019 (Covid-19) disrupted the in-person teaching format of anatomy. To study changes in gross anatomy education that occurred during August-December, 2020 compared to before the pandemic, an online survey was distributed to anatomy educators. The 191 responses received were analyzed in total and by academic program, geographic region, and institution type. Cadaver use decreased overall (before: 74.1 ± 34.1%, during: 50.3 ± 43.0%, P < 0.0001), as well as across allopathic and osteopathic medicine, therapy, undergraduate, and veterinary programs (P < 0.05), but remained unchanged for other programs (P > 0.05). Cadaver use decreased internationally and in the US (P < 0.0001), at public and private (P < 0.0001) institutions, and among allopathic medical programs in Northeastern, Central, and Southern (P < 0.05), but not Western, US geographical regions. Laboratories during Covid-19 were delivered through synchronous (59%), asynchronous (4%), or mixed (37%) formats (P < 0.0001) and utilized digital resources (47%), dissection (32%), and/or prosection (21%) (P < 0.0001). The practical laboratory examination persisted during Covid-19 (P = 0.419); however, the setting and materials shifted to computer-based (P < 0.0001) and image-based (P < 0.0001), respectively. In-person lecture decreased during Covid-19 (before: 88%, during: 24%, P = 0.003). When anatomy digital resources were categorized, dissection media, interactive software, and open-access content increased (P ≤ 0.008), with specific increases in BlueLink, Acland's Videos, and Complete Anatomy (P < 0.05). This study provided evidence of how gross anatomy educators continued to adapt their courses past the early stages of the pandemic.

Sharing a Preliminary Experience of an Effective Online Teaching Strategy for Physiology Practicals

To counter the challenge posed by the suspension of face-to-face classes due to COVID-19 imposed restrictions, a plan was formulated to conduct practical physiology classes for first-year undergraduate medical students at a newly established medical college in India. The students were provided with study materials before the scheduled class along with an assignment based on it. The class was taken on an online platform, with live practical demonstration on a full-body mannequin. This was followed by discussion in small groups. This strategy actively engaged both teachers and students and provided an effective model for imparting practical skills on an online platform.

Virtual delivery: a panacea for the financial and ethical challenges associated with physiology laboratory classes?

There has been a gradual shift in the delivery of physiology laboratory classes over the last 30 years. For many, wet-lab demonstrations using animal tissues have been reduced or replaced with student-led investigations where students are both subjects and researchers. Despite these changes, expectations remain that physiology courses should include a practical component to encourage deeper and higher-order learning. Wet-lab tissue experiments and student-based group research formats can be expensive to run, associated with various ethical constraints, and, as discovered in these times of COVID-19, difficult to operate while adhering to physical distancing. We address the proposition that online and/or remote delivery of laboratory classes using digital technologies may provide a solution to both financial and ethical constraints of on-campus laboratory classes. Our discussions, as an international group of 10 physiologists from the United States, the United Kingdom, Canada, and Australia, revealed that although some of the financial and ethical constraints of using animal tissues and student-led investigations were addressed by the introduction of online alternatives, the construction and maintenance of online delivery modes could also be expensive and ethical issues, not previously considered, included digital equity and student data security. There was also a collective perception that if face-to-face laboratory classes were changed to an entirely virtual mode there was a risk that some intended learning outcomes would not be met. It was concluded that the "ideal" approach is likely a hybrid model whereby student attendance in face-to-face, on-campus classes is supported with interactive digital content either developed in house or obtained through third-party providers.

Faustino-Rocha A, A. Oliveira P, Mesquita J, Vala H. Virtual Physiology: A Tool for the 21st Century

Veterinary physiology is a basic curricular unit for every course within the veterinary field. It is mandatory to understand how the animal body works, and what to expect of a healthy body, in order to recognize any misfunction, and to be able to treat it. Classic physiology teaching involves wet labs, much equipment, many reagents, some animals, and a lot of time. But times are changing. In the 21st century, it is expected that the teaching and learning process can be more active and attractive, motivating students to learn better. It is necessary to understand what students like, and to introduce novelties into the school routine. The use of a game-based learning, using “new” technologies, creating virtual experiences and labs, reducing the costs of reagents, equipment, and especially reducing the use of animals, will be the future for physiology teaching.
