[About the first publication of I.M. Sechenov. (To the 195th anniversary of his birth)]. / O pervoi publikatsii I.M. Sechenova. (K 195-letiyu so dnya rozhdeniya).

Ivan Mikhailovich Sechenov is a Russian physiologist, a natural scientist, and the creator of the Russian physiological school. The classic work «Reflexes of the Brain¼, published in 1863, became revolutionary in its own way for medicine and society, since the reflex nature of conscious and unconscious activity was proved. Along with numerous well-known scientific works, there is an early student publication in the Moscow Medical Journal published by A. I. Polunin. It describes the medical history of a patient with a tumor who was unsuccessfully treated for a long time in accordance with the humoral theory of pathology. This publication makes it possible to understand why I. M. Sechenov became disillusioned with practical medicine, but found his vocation in the study of physiology. The article is devoted to the 195th anniversary of the birth of I. M. Sechenov.

Assessment of educational technology in lactation physiology by health students.

OBJECTIVES: to assess the suitability, facilitators, and barriers of using a video clip for teaching lactation physiology to health students. METHODS: a cross-sectional study was conducted with online data collection at a higher education institution, using the Assistive Technology Assessment Instrument and open-ended questions. The sample consisted of 88 students. RESULTS: the video clip was deemed suitable in all attributes. Facilitators identified included attractiveness, musicality, and ease of access. Barriers noted were the music's speed and the necessity for prior knowledge. The video clip achieved adequate scores for interactivity (1.71), purpose (1.77), relevance (1.64), and clarity (1.77). The overall average of the attributes was 1.72. CONCLUSIONS: the video clip can serve as an effective learning strategy to enhance hybrid education, potentially contributing to the promotion and support of breastfeeding. However, some barriers underscore the importance of prior knowledge for a complete understanding of the content.

Using case-based learning supported by role-playing situational teaching method in endocrine physiology education.

Embedding clinically relevant learning experience in basic science subjects is desired for the preclinical phase of undergraduate medical education. The present study aimed to modify case-based learning (CBL) with a role-playing situational teaching method and assess the student feedback and learning effect. One hundred seventy-six sophomore students majoring in clinical medicine from Harbin Medical University were randomly divided into two groups: the control group (n = 90), who received traditional hybrid teaching, and the experimental group (n = 86), who received the role-playing situational teaching. Students in the experimental group were given a 1-wk preclass preparation to dramatize a hyperthyroidism scenario through online autonomous learning of thyroid physiology and performed the patient's consultation process in class, followed by a student presentation about key points of lecture content and a question-driven discussion. A posttest and questionnaire survey were conducted after class. The test scores of the two groups had no statistical differences, whereas the rate of excellence (high scores) of the experimental group was significantly higher than that of the control group. Furthermore, the record of online self-directed learning engagements was significantly improved in the experimental group. In the questionnaire, >70% of the students showed positive attitudes toward the role-playing situational teaching method and were willing to participate in other chapters of the physiology course. Such results show that CBL supported by a role-playing situational teaching method encourages active learning and improves the application of basic knowledge of physiology, which can be incorporated in the preclinical curricula to bridge the gap between theory and practice.NEW & NOTEWORTHY Formal application through structured role-play is often overlooked in physiology education. In traditional case-based learning (CBL), clinical cases are the subject and unfocused discussion often occurs. The present study aimed to modify CBL with a role-playing situational teaching method and assess the student feedback and learning effect. The results show that the new teaching model encourages active learning and improves the application of basic knowledge of physiology.

Why ask why? Toward coordinating knowledge of proximate and ultimate explanations in physiology.

In physiology education, students must learn to recognize and construct causal explanations. This challenges students, in part, because causal explanations in biology manifest in different varieties. Unlike other natural sciences, causal mechanisms in physiology support physiological functions and reflect biological adaptations. Therefore, students must distinguish between questions that prompt a proximate or an ultimate explanation. In the present investigation, we aimed to determine how these different varieties of student knowledge coordinate within students' written explanations. Prior research in science education demonstrates that students present specific challenges when distinguishing between proximate and ultimate explanations: students appear to conflate the two or construct other nonmechanistic explanations. This investigation, however, demonstrates that analytic frameworks can distinguish between students' proximate and ultimate explanations when they are provided explanatory scaffolds that contextualize questions. Moreover, these scaffolds and prompts help students distinguish between physiological functions and the cellular and molecular mechanisms that underpin them. Together, these findings deliver insight into the context-sensitive nature of student knowledge in physiology education and offer an analytic framework for identifying and characterizing student knowledge in physiology.NEW & NOTEWORTHY Why ask why? How questions posed in physiology task students with developing their mechanistic reasoning. Why questions sometimes undermine this reasoning. Prior research, however, also illustrates that framing the context of a question explicitly supports students in distinguishing between question types. We further illustrate how providing such context in the form of explanatory scaffolds and prompts allows students to tap different and useful varieties of knowledge when constructing written explanations.

Collaborative online international learning in physiology: a case study.

Internationalization in higher education is essential, and although active learning methodologies are increasing and allow students to develop transversal skills, most still have a very local scope. In this context, the Collaborative Online International Learning (COIL) methodology is an interesting approach to benefit the students' development. It consists of an online program that involves creating multicultural teams to develop a specific learning project. Although this methodology is expanding, its use in physiology is still scarce. This paper aims to show an example of applying COIL methodology in physiology topics to enhance higher-education students' innovation and business skills. Our example project developed a sports-assessment service concept focused on physiology and biomechanics assessments. The program involved teams from Brazil, Germany, and Spain, comprising undergraduate and master students. Over 7 weeks, these teams, mentored by professors and researchers, engaged in workshops covering COIL methodology, business model design, executive summary planning, economic analyses, and communication techniques. Key outcomes included learning new concepts, developing soft skills, building confidence in innovative solution proposals, and experiencing diverse cultures. Challenges faced were language barriers, scheduling, task complexity, and logistical issues. This experience confirms the effectiveness of incorporating programs using COIL methodology into educational curriculums. Doing so exposes physiology students to innovation, entrepreneurship, and business creation while strengthening their professional connections and opening up postgraduation opportunities.NEW & NOTEWORTHY Although the Collaborative Online International Learning (COIL) methodology is expanding, its use in physiology is still scarce. Our example COIL project of 7 weeks developed a sports-assessment service concept focused on physiology and biomechanics assessments. The program involved teams from Brazil, Germany, and Spain, comprising undergraduate and master's students. Students perceived extracurricular activities in this format as beneficial. Coaches also expressed positive views about such initiatives, noting benefits for students and their development.

The Inverted Case Study Technique: changing the traditional case-study approach to prioritize physiological mechanisms over correct diagnosis and treatment.

The traditional case study has been used as a learning tool for the past 100 years, and in our program, graduate physiology students are presented with a real-world scenario and must determine the diagnosis and treatment of the patient. We found that students defaulted to memorization of disease with treatment and bypassed gaining an understanding of the mechanistic physiology behind disease and treatment. To adjust our student's approach, we developed a novel way to enhance student learning. To accomplish this shift from memorization to physiological mastery, we created the Inverted Case Study. This approach diverges from the traditional model in that students are given the diagnosis and treatment beforehand and are tasked with explaining the actual physiology of the case. In this way, students can no longer rely on the memorization of symptoms-disease-treatment but rather gain a solid understanding of the physiological mechanisms of the disease since that is the focus of the Inverted Case Study Technique. The Inverted Case Study approach is an effective approach to apply and hone critical thinking skills.NEW & NOTEWORTHY This article presents a novel approach to century-old learning techniques that enhances students' self-reported learning and also their attitudes toward learning mechanistic physiology and increases their perception of preparedness for professional school.

Modeling the extracellular potential generated by a muscle fiber as the output signal of a convolutional system.

A central topic in Bioelectricity is the generation of the extracellular potential that results from the propagation of a transmembrane action potential along the muscle fiber. However, the way in which the extracellular potential is determined by the propagating action potential is difficult to describe, conceptualize, and visualize. Moreover, traditional quantitative approaches aimed at modeling extracellular potentials involve complex mathematical formulations, which do not allow students to visualize how the extracellular potential is generated around the active fiber. The present study is aimed at presenting a novel pedagogical approach to teaching the generation of extracellular potentials produced by muscle fibers based on the convolution operation. The effectiveness of this convolutional model was tested using a written exam and a satisfaction survey. Most students reported that a great advantage of this model was that it simplifies the problem by dividing it into three distinct components: 1) the input signal (associated with the action potential), 2) the impulse response (linked to the system formed by the fiber and the recording electrode), and 3) the output signal (the extracellular potential). Another key aspect of the present approach was that the input signal was represented by a sequence of electric dipoles, which allowed students to visualize the individual contribution of each dipole to the resulting extracellular potential. The results of the survey indicate that the combination of basic principles of electrical fields and intuitive graphical representations largely improves students' understanding of Bioelectricity concepts and enhances their motivation to complete their studies of biomedical engineering.NEW & NOTEWORTHY We presented a new pedagogical method to describe the extracellular potential generated by a muscle fiber as the output signal of the convolution between an input signal and an impulse response. The input signal represents the action potential traveling along the fiber, and the impulse response represents the system formed by the fiber and the recording electrode. The output signal is the summation of the contributions from all individual dipoles that formed the input signal.

A partially flipped physiology classroom improves the deep learning approach of medical students.

This study aimed to compare the impact of the partially flipped physiology classroom (PFC) and the traditional lecture-based classroom (TLC) on students' learning approaches. The study was conducted over 5 mo at Xiangya School of Medicine from February to July 2022 and comprised 71 students majoring in clinical medicine. The experimental group (n = 32) received PFC teaching, whereas the control group (n = 39) received TLC. The Revised Two-Factor Study Process Questionnaire (R-SPQ-2F) was used to assess the impact of different teaching methods on students' learning approaches. After the PFC, students got significantly higher scores on deep learning approach (Z = -3.133, P < 0.05). Conversely, after the TLC students showed significantly higher scores on surface learning approach (Z = -2.259, P < 0.05). After the course, students in the PFC group scored significantly higher in deep learning strategy than those in the TLC group (Z = -2.196, P < 0.05). The PFC model had a positive impact on deep learning motive and strategy, leading to an improvement in the deep approach, which is beneficial for the long-term development of students. In contrast, the TLC model only improved the surface learning approach. The study implies that educators should consider implementing PFC to enhance students' learning approaches.NEW & NOTEWORTHY In this article, we compare the impact of the partially flipped classroom (PFC) and the traditional lecture classroom (TLC) in a physiology course on medical students' learning approaches. We found that the PFC benefited students by significantly enhancing their deep learning motive, strategy, and approach, which was good for them. However, the TLC model only improved the surface learning motive and approach.

Exploring educational transformations through the Innovative Flipped Learning Instruction Project Symposium.

The flipped classroom is an innovative pedagogy that shifts content delivery outside the classroom, utilizing in-class time for interactive learning. The preclass and in-class activities in this framework encourage individualized learning and collaborative problem-solving among students, fostering engagement. The Innovative Flipped Learning Instruction Project (IFLIP) conducted faculty development workshops over 4 years, guiding science, technology, engineering, and mathematics (STEM) faculty in integrating flipped teaching (FT) into their courses. The research aimed to assess its impact on pedagogical practices, explore its effectiveness, and provide a framework to implement FT across multiple institutions. It sought to evaluate the experiences of these educators throughout the transitional period of instructional change. In the fourth year of this project, a symposium was organized for IFLIP participants to share their experiences and findings concerning FT. This symposium helped promote collaboration among IFLIP participants and faculty interested in FT to disseminate participants' knowledge and experiences in implementing FT strategies. A survey conducted at the end of the symposium indicated that faculty participants with FT experience continued to embrace this pedagogy, and the new adopters expressed intentions to incorporate it into their courses. The survey revealed positive responses: 93% of respondents plan to integrate FT methods in future classes, 90% gained new information from the symposium and intend to implement it, and 91% are likely to recommend FT to colleagues. Ultimately, the symposium underscored the transformative impact of FT in empowering educators to deepen students' conceptual understanding, emphasizing the significance of this pedagogical approach in advancing the quality of education.NEW & NOTEWORTHY Flipped pedagogy shifts content delivery outside the classroom, emphasizing interactive learning during in-class time. The Innovative Flipped Learning Instruction Project (IFLIP) guided science, technology, engineering, and mathematics (STEM) faculty in integrating flipped teaching (FT), tracked experiences during this transition, and provided a framework for FT implementation. A fourth-year symposium fostered collaboration, revealing sustained enthusiasm for FT. The symposium underscored its transformative impact on deepening students' understanding, highlighting its significance in enhancing education quality.

Empowering students to create their dramatizations increases understanding of physiology.

Complex subjects such as physiology can be challenging for students to learn. These challenges are not uncommon in implementing the learning process in physiology and affect learning outcomes. Dramatization is an interactive and effective method to improve learning outcomes. In a project designed by senior medical students, junior medical students were guided in creating dramatizations related to three topics. Senior students were trained and assisted to prepare scenarios and make videos. The dramatizations were then carried out with junior medical students to help them better understand physiology and pathophysiology topics. A group of junior students receiving the same topics in a lecture format served as a control group. Pretest and posttest questionnaires were used to measure the improvement of learning outcomes. Assessment results showed an increase in performance in both groups. This study shows that dramatizations provide an effective alternative to lectures for instructing junior medical students.NEW & NOTEWORTHY The preparation of dramatizations involved students. The ideas, analogies, and dramatizations were originally from students. Dramatization is an alternative form of understanding learning objectives of medical physiology in an interesting way to increase motivation.

Alignment of learning objectives, assessments, and active learning to promote critical thinking in a first-year medical physiology course: lessons learned.

Medical students must be adept at critical thinking to successfully meet the learning objectives of their preclinical coursework. To encourage student success on assessments, the course director of a first-year medical physiology course emphasized the use of learning objectives that were explicitly aligned with formative assessments in class. The course director introduced the physiology discipline, learning objectives, and evidence-based methods of studying to students on the first day of class. Thereafter, class sessions started with a review of the learning objectives for that session and included active learning opportunities such as retrieval practice. The instructor provided short answer formative assessments aligned with the learning objectives, intended to help the students apply and integrate the concepts. Midsemester, students received a link to an online survey with questions on studying habits, class attendance, and student engagement. After finals, students were invited to participate in focus groups about their class experience. A qualitative researcher moderated focus groups, recorded responses, and analyzed the narrative data. Of 175 students, 95 submitted anonymous online surveys. Student engagement was significantly correlated with in-person class attendance (r = 0.26, T = 2.5, P = 0.01) and the completion of open-ended formative assessments (r = 0.33, T = 3.3, P = 0.001). Focus groups were held via videoconference. From the class, 14 students participated in 4 focus groups; focus group participants were mostly women (11 of 14) and mostly in-class attendees (13 of 14). The students in this sample valued critical thinking but misunderstood expectations on exams and few students used learning objectives to study.NEW & NOTEWORTHY We introduced formative assessments and study techniques to first-year medical students in a physiology course. Mastery of learning objectives was emphasized as the key to success. We asked how they studied physiology through an anonymous online survey and focus group interviews. The students enjoyed physiology but had difficulty with exam expectations. Helping students use learning objectives to guide their study may lead to improved exam scores. It may also help administrators meet their curriculum goals.
