The structure and function relationship is a core concept identified by physiology faculty. Prior research has shown this may be a difficult concept for students to understand. Formative written assessments, such as short answer essay questions, allow students to demonstrate their thinking by encouraging students to use their diverse ideas to construct their responses. Varying the context of a question, such as the inclusion of a scenario, may be used to provide insight into the different stages of students' emerging biological expertise. Short answer questions based on the core concept structure↔function were administered to students in a junior level General Physiology course and a sophomore level Human Anatomy and Physiology course at a large southeastern public university. Questions were based on the integumentary, muscular, digestive, and cardiovascular systems. Student responses were scored with a conceptual rubric developed for each question prompt as well as each organ system represented in the question prompts. Students were interviewed to determine if their responses to the short answer questions accurately reflected their thinking. Less than half of the student responses in this study demonstrated a conceptual understanding of the structure-function relationship. Students demonstrated different conceptual understanding of structure↔function concepts depending on the question prompt with a scenario versus the question prompt without a scenario. The question prompts with scenarios versus non-scenarios provided a different context, which may have influenced student explanations. These results suggest that instructors should provide students with questions in varying contexts to allow students to demonstrate their heterogeneous ideas about a concept.NEW & NOTEWORTHY Formative assessment provides feedback to both students and instructors about the process of learning. The core concept structure-function provides a foundation upon which many topics in anatomy and physiology can be built across all levels of organization. This study contributes to existing research about student conceptual understanding of the core concepts. Implications for practitioners include the design of formative assessments and a suite of questions to be used to gauge student understanding of structure-function.

The idea of teaching science through music has undeniable appeal in implying that learning can be engaging and fun while also covering content efficiently. Indeed, there is little doubt that songs can be uniquely memorable, suggesting mnemonic options for core content. However, many classroom implementations of science music have limitations such as an overemphasis on rote memorization, rather than a constructivist building of understanding. In this brief review, we ask how music might facilitate the learning of science content in a manner consistent with the well-known pedagogical framework of Universal Design for Learning (UDL). In our view, UDL suggests certain distinct possible benefits of incorporating music into curricula, leading us to propose four models of practice. These four models are as follows: 1) students enjoy music together, 2) students critically analyze songs as texts, 3) students creatively augment existing songs, and 4) students create new songs. Model 1 can contribute to an inclusive learning environment, while models 2-4 can encourage cognitively rich active learning, and models 3-4 can additionally help students channel scientific understanding into the creation of authentic products. We conclude with comments on logistical issues that arise in implementing these four models, including the use of appropriate rubrics and the prioritization of artistic quality.NEW & NOTEWORTHY Instructors and students often find it fun to incorporate music into science classes. However, the casual usage of music in this context can unintentionally convey that science courses are mostly about memorizing scientific facts. In this article, the authors argue for a more nuanced approach to teaching science with music, rooted in Universal Design for Learning (UDL).

Australia-wide consensus was reached on seven core concepts of physiology, which included homeostasis, a fundamental concept for students to understand as they develop their basic knowledge of physiological regulatory mechanisms. The term homeostasis is most commonly used to describe how the internal environment of mammalian systems maintains relative constancy. The descriptor "the internal environment of the organism is actively regulated by the responses of cells, tissues, and organs through feedback systems" was unpacked by a team of three Australian Physiology educators into 5 themes and 18 subthemes arranged in a hierarchy. Using a five-point Likert scale, the unpacked concept was rated by 24 physiology educators from 24 Australian Universities for level of importance and level of difficulty for students. Survey data were analyzed using a one-way ANOVA to compare between and within concept themes and subthemes. There were no differences in main themes for level of importance, with all ratings between essential or important. Theme 1: the organism has regulatory mechanisms to maintain a relatively stable internal environment, a process known as homeostasis was almost unanimously rated as essential. Difficulty ratings for unpacked concept themes averaged between slightly difficult and moderately difficult. The Australian team concurred with published literature that there are inconsistencies in the way the critical components of homeostatic systems are represented and interpreted. We aimed to simplify the components of the concept so that undergraduates would be able to easily identify the language used and build on their knowledge.NEW & NOTEWORTHY The homeostasis core concept of physiology was defined and unpacked by an Australian team with the goal of constructing a resource that will improve learning and teaching of this core physiology concept in an Australian Higher Education context.

Overweight and obesity rates continue to rise and appear unlikely to abate. While physical activity (PA) is an important contributor to health and successful weight maintenance, exercise science and health students (ESHS) often endorse negative weight status biases that could undermine PA promotion. This experiential learning activity was intended to help foster weight status understanding among ESHS. Nine ESHS completed the learning activity across two 75-minute class periods. During the initial didactic lesson, the instructor presented on psychophysiological responses to PA among normal and overweight individuals. During the second simulation lesson, the students first responded with their predictions of how the experience of four common physical activities, including shoe tying, brisk walking, running, and climbing and descending stairs, could differ with additional body mass. Next, students twice completed each of the four physical activities while first wearing a weighted vest that simulated 16 lb followed by 32 lb of additional mass. At the beginning, middle, and end of the stair climb and descent, the students provided ratings of affective valence (i.e., pleasure-displeasure). Following the PA simulations, the students wrote about their experiences and how their PA promotion strategies could be modified for overweight clients. The changes in student qualitative responses, particularly following the 32-lb simulations, suggested an increased understanding of the psychophysiological experience of PA while carrying additional mass. Learning activities like this one may be meaningful additions to ESHS curricula aiming to mitigate weight status bias and improve PA promotion among overweight clients.NEW & NOTEWORTHY Exercise science and health students (ESHS) often enter the field with the noble intention to help people become more physically active. However, many ESHS endorse negative weight status biases that could undermine health promotion efforts among overweight individuals. Experiential learning simulations that approximate the experiences of physical activity while overweight may be helpful tools to foster understanding and reduce bias. This article outlines a two-part didactic/simulation learning activity to promote weight status understanding among ESHS.

As one element of an extensive revision to program curriculum, the Integrative Physiology and Health Science Department at a small, private, liberal arts institution developed a novel introductory course for the major, focusing specifically on the "core concepts" of physiology. Intended to provide the initial step in explicit scaffolding for student success and, ultimately, transfer of knowledge across the curriculum, development and assessment of the first offering of the course were completed. In the fall of 2021, IPH 131: Foundations in Physiology was launched. The specific core concepts covered were as follows: causality, scientific reasoning, physics/chemistry, structure-function, homeostasis, flow-down gradients, cell membrane, energy, cell-cell communication, and interdependence/integration. To assess student learning, the Phys-MAPS (Measuring Achievement and Progress in Science for Physiology) assessment tool was administered to students during the first week of class and again in the final week of the semester. Average scores revealed significant learning gains by the end of the semester (0.497 ± 0.058 vs. 0.538 ± 0.108 correct as a proportion of the total number of questions, P = 0.0096). While a modest gain in learning outcomes, these data provide early evidence that a course specifically addressing the core concepts of physiology can be an appropriate introduction to the physiology curriculum.NEW & NOTEWORTHY This article will detail the development and implementation of an introductory course using the "core concepts." Specifics of course design, assessment, and challenges encountered will be presented for those interested in this approach.

An Australia-wide consensus was reached on seven core concepts of physiology, one of which was cell-cell communication. Three physiology educators from a "core concepts" Delphi task force "unpacked" this core concept into seven different themes and 60 subthemes. Cell-cell communication, previously unpacked and validated, was modified for an Australian audience to include emerging knowledge and adapted to increase student accessibility. The unpacked hierarchical framework for this core concept was rated by 24 physiology educators from separate Australian universities, using a five-point scale for level of importance for student understanding (ranging from 1 = Essential to 5 = Not Important) and level of difficulty (ranging from 1 = Very Difficult to 5 = Not Difficult). Data were analyzed with the Kruskal-Wallis test with Dunn's multiple comparison test. The seven themes were rated within a narrow range of importance (1.13-2.4), with ratings of Essential or Important, and statistically significant differences between the themes (P < 0.0001, n = 7). The variance for the difficulty rating was higher than for importance, ranging from 2.15 (Difficult) to 3.45 (between Moderately Difficult and Slightly Difficult). Qualitatively, it was suggested that some subthemes were similar and that these could be grouped. However, all themes and subthemes were ranked as Important, validating this framework. Once finalized and adopted across Australian universities, the unpacked core concept for cell-cell communication will enable the generation of tools and resources for physiology educators and improvements in consistency across curricula.NEW & NOTEWORTHY Seven core concepts, including cell-cell communication, were identified by an Australian Delphi task force of physiology educators. The previously "unpacked" concept was adapted for Australian educators and students to develop a framework with seven themes and 60 subthemes. The framework was successfully validated by the original Delphi panel of educators and will provide a valuable resource for teaching and learning in Australian universities.

Students in an animal physiology course are required to have completed prerequisite cell biology and genetics courses that include discussion of basic properties and functions of the cell membrane. However, while many students remember basic information about membrane structure, they often have difficulty relating that structure to membrane functions, such as vesicular transport, active transport, osmosis, and current flow across the membrane. To better understand what students recall about the cell membrane, students were given an open-ended prompt to draw what they know about the structure and function of the animal cell membrane. This activity was repeated 1-2 weeks after finishing discussion of the cell membrane in class, with an emphasis on the concepts of membrane transport and a related core concept, flow along gradients. Student responses were analyzed using the conceptual framework for the "cell membrane" core concept published by Michael and Modell (Michael J, Modell H. Adv Physiol Educ 43: 373-377, 2019). Before covering this content in class, the majority of submissions included a representation of the cell membrane as a phospholipid bilayer, and a high percentage also included membrane proteins or the fluid mosaic model. Similar percentages of students included these concepts in the postcoverage drawing. However, other components of the conceptual framework were included less frequently or not at all before covering the content in class but improved dramatically afterward. This activity provides information about what students recall from prior coursework and which concepts need to be revisited, and it can provide a complementary assessment of student understanding of the core concept of the cell membrane.NEW & NOTEWORTHY Student-constructed drawings can give insight into student understanding, and misunderstandings, of core concepts about the cell membrane.

The analysis of spontaneous tail coiling (STC) in zebrafish embryos is a functional parameter that allows the study of motor development. It has recently gained relevance as a biomarker to assess the neurotoxicity of environmental substances. Its practicability in the laboratory makes it an excellent pedagogical tool for promoting students' inquiry skills. However, the time and cost of materials and facilities limit their usage in undergraduate laboratories. This study presents the design of a computer-based educational module called ZebraSTMe, which is based on a tail coiling assay and aims to improve science process skills in undergraduate students by connecting them to relevant and novel content. We evaluate students' perception of learning, the quality of materials used, and the knowledge gained. Our results show that students perceived an improvement in their statistical analysis, representation, and discussion of experimental data. Additionally, the students evaluated the quality and ease of use of the materials and provided feedback for revision. A thematic analysis of the opinions revealed that the module activities promoted students' reflection on their professional strengths and weaknesses.NEW & NOTEWORTHY ZebraSTMe is a novel computer-based educational module that utilizes spontaneous tail coiling analysis in zebrafish embryos to enhance undergraduate students' scientific inquiry skills. By addressing the challenges of time, cost, and laboratory resources, the module improves students' science process skills and promotes reflection on their professional strengths and weaknesses. The innovative ZebraSTMe exemplifies the potential of integrating cutting-edge research topics into undergraduate education, leading to more engaging and effective learning experiences in physiology and other scientific disciplines.

The usefulness of virtual reality (VR) technology in physiology education is largely unexplored. Although VR has the potential to enrich learning experience by enhancing the spatial awareness of students, it is unclear whether VR contributes to active learning of physiology. In the present study, we used a mixed-method research approach to investigate students' perceptions of physiology learning based on VR simulations. Quantitative and qualitative data indicate that the implementation of VR learning environments improves the quality of physiology education by promoting active learning in terms of interactive engagement, interest, problem-solving skills, and feedback. In the Technology-Enabled Active Learning Inventory, which consisted of 20 questions to which students responded along a 7-point Likert scale, the majority of students agreed that VR learning of physiology not only stimulated their curiosity (77%; P < 0.001) but also allowed them to obtain knowledge through diverse formats (76%; P < 0.001), participate in thought-provoking dialogue (72%; P < 0.001), and interact better with peers (72%; P < 0.001). Positive responses in the social, cognitive, behavioral, and evaluative domains of active learning were received from students across different disciplines, including medicine, Chinese medicine, biomedical sciences, and biomedical engineering. Their written feedback showed that VR enhanced their interest in physiology and facilitated the visualization of physiological processes to improve their learning. Overall, this study supports that the integration of VR technology into physiology courses can be an effective teaching strategy.NEW & NOTEWORTHY Virtual reality (VR) improves physiology education by promoting active learning in terms of interactive engagement, interest, problem-solving skills, and feedback. Positive responses toward multiple components of active learning were received from students across different disciplines. The majority of students agreed that VR learning of physiology not only stimulated their curiosity but also allowed them to obtain knowledge through diverse formats, participate in thought-provoking dialogue, and interact better with peers.

The COVID-19 pandemic and worldwide lockdowns brought major changes in education systems. There was a sudden obligatory shift toward utilization of digital resources for teaching and learning purposes. Medical education, specifically physiology teaching, comprises hands-on training in the laboratory. It is challenging to offer a course like physiology in a virtual format. The objective of this study was to assess the effectiveness and influence of virtual classroom technology on online physiology education in a sample size of 83 first-year MBBS undergraduates. A questionnaire comprising questions related to technology accessibility and utilization, comprehensibility and effectiveness of instructions, faculty proficiency, and learning outcomes was administered to the group. The responses were collected and analyzed. Validation through principal components and factor analysis showed that online teaching is not very effective and has a limited application in the physiology education of undergraduate MBBS students. Our study also revealed that virtual physiology teaching of undergraduate medical students during the COVID-19 pandemic had a moderate level of effectiveness.NEW & NOTEWORTHY In the present qualitative study, we have conducted and validated an online physiology teaching platform at a medical college to continue medical education during the peak times of the COVID-19 pandemic and prolonged lockdowns. Furthermore, we have evaluated the effectiveness of online physiology teaching through multidimensional feedback from undergraduate MBBS students. It is experimental evidence of inadequate sustainability, moderate efficacy, limited application, and poor first-hand experience gained by the students in virtual physiology teaching in a preclinical and clinical setting.
