Immersive virtual reality-based learning as a supplement for biomedical engineering labs: challenges faced and lessons learned.

Introduction: Immersive virtual reality (VR) based laboratory demonstrations have been gaining traction in STEM education as they can provide virtual hands-on experience. VR can also facilitate experiential and visual learning and enhanced retention. However, several optimizations of the implementation, in-depth analyses of advantages and trade-offs of the technology, and assessment of receptivity of modern techniques in STEM education are required to ensure better utilization of VR-based labs. Methods: In this study, we developed VR-based demonstrations for a biomolecular engineering laboratory and assessed their effectiveness using surveys containing free responses and 5-point Likert scale-based questions. Insta360 Pro2 camera and Meta Quest 2 headsets were used in combination with an in-person lab. A cohort of 53 students watched the experimental demonstration on VR headsets in the lab after a brief lab overview in person and then performed the experiments in the lab. Results: Only 28.29% of students reported experiencing some form of discomfort after using the advanced VR equipment as opposed to 63.63% of students from the previous cohort. About 40% of the students reported that VR eliminated or reduced auditory and visual distractions from the environment, the length of the videos was appropriate, and they received enough information to understand the tasks. Discussion: The traditional lab method was found to be more suitable for explaining background information and lab concepts while the VR was found to be suitable for demonstrating lab procedures and tasks. Analyzing open-ended questions revealed several factors and recommendations to overcome the potential challenges and pitfalls of integrating VR with traditional modes of learning. This study provides key insights to help optimize the implementation of immersive VR to effectively supplement in-person learning experiences.

Examining Science and Technology/Engineering Educators' Views of Teaching Biomedical Concepts Through Physical Computing.

Programming and automation continue to evolve rapidly and advance the capabilities of science, technology, engineering, and mathematics (STEM) fields. However, physical computing (the integration of programming and interactive physical devices) integrated within biomedical contexts remains an area of limited focus in secondary STEM education programs. As this is an emerging area, many educators may not be well prepared to teach physical computing concepts within authentic biomedical contexts. This shortcoming provided the rationale for this study, to examine if professional development (PD) had a noticeable influence on high school science and technology and engineering (T&E) teachers' (1) perceptions of teaching biomedical and computational thinking (CT) concepts and (2) plans to integrate physical computing within the context of authentic biomedical engineering challenges. The findings revealed a significant difference in the amount of biomedical and CT concepts that teachers planned to implement as a result of the PD. Using a modified version of the Science Teaching Efficacy Belief Instrument (STEBI-A) Riggs and Enochs in Science Education, 74(6), 625-637 (1990), analyses revealed significant gains in teachers' self-efficacy toward teaching both biomedical and CT concepts from the PD. Further analyses revealed that teachers reported increases in their perceived knowledge of biomedical and CT concepts and a significant increase in their intent to collaborate with a science or T&E educator outside of their content area. This study provides implications for researchers and educators to integrate more biomedical and physical computing instruction at the secondary education level.

Ophthalmological instruments of Al-Halabi fill in a gap in the biomedical engineering history.

Al-Halabi is an intriguing ophthalmologist who invented numerous surgical instruments for treating various eye diseases. The illustrations of such instruments in his invaluable book "Kitab Al-Kafi fi Al-Kuhl" reflect his willingness to teach. Moreover, he included in his book a magnificent illustration of the anatomical structure of the eye. The book reflects Al-Halabi's medical practice and teaching and shows several advanced medical techniques and tools. His invaluable comments reflect his deep experimental observations in the field of ophthalmology. The current article provides proof that Al-Halabi is one of our early biomedical engineers from more than 800 years ago. Al-Halabi represents a ring in the chain of biomedical engineering history. His surgical instruments represent the biomechanics field. Al-Halabi should be acknowledged among the biomedical engineering students for his various contributions in the field of surgical instruments.

Post-graduation Plans of Undergraduate BME Students: Gender, Self-efficacy, Value, and Identity Beliefs.

This study investigates career intentions and students' engineering attitudes in BME, with a focus on gender differences. Data from n = 716 undergraduate biomedical engineering students at a large public research institution in the United States were analyzed using hierarchical agglomerative cluster analysis. Results revealed five clusters of intended post-graduation plans: Engineering Job and Graduate School, Any Job, Non-Engineering Job and Graduate School, Any Option, and Any Graduate School. Women were evenly distributed across clusters; there was no evidence of gendered career preferences. The main findings in regard to engineering attitudes reveal significant differences by cluster in interest, attainment value, utility value, and professional identity, but not in academic self-efficacy. Yet, within clusters the only gender differences were women's lower engineering academic self-efficacy, interest and professional identity compared to men. Implications and areas of future research are discussed.

Using Virtual Reality in Biomedical Engineering Education.

This study explored virtual reality (VR) as an educational tool to offer immersive and experiential learning environments to biomedical engineering (BME) students. VR and traditional two-dimensional (2D) videos were created and used to teach required communication skills to BME students' while working with clinical partners in healthcare settings. The videos of interdisciplinary teams (engineering and nursing students) tackling medical device-related problems, similar to those commonly observed in healthcare settings, were shown to BME students. Student surveys indicated that, through VR videos, they felt more immersed in real-world clinical scenarios while learning about the clinical problems, each team-member's areas of expertise, their roles and responsibilities, and how an interdisciplinary team operated collectively to solve a problem in the presented settings. Students with a prior in-person immersion experience, in the presented settings, reported VR videos to serve as a possible alternative to in-person immersion and a useful tool for their preparedness for real-world clinical immersion. We concluded that VR holds promise as an educational tool to offer simulated clinical scenarios that are effective in training BME students for interprofessional collaborations.

Fifty Years of Biomedical Engineering Undergraduate Education.

Undergraduate education in biomedical engineering (BME) and bioengineering (BioE) has been in place for more than 50 years. It has been important in shaping the field as a whole. The early undergraduate programs developed shortly after BME graduate programs, as universities sought to capitalize on the interest of students and the practical advantages of having BME departments that could control their own resources and curriculum. Unlike other engineering fields, BME did not rely initially on a market for graduates in industry, although BME graduates subsequently have found many opportunities. BME undergraduate programs exploded in the 2000s with funding from the Whitaker Foundation and resources from other agencies such as the National Institute of Biomedical Imaging and Bioengineering. The number of programs appears to be reaching a plateau, with 118 accredited programs in the United States at present. We show that there is a core of material that most undergraduates are expected to know, which is different from the knowledge base of other engineers not only in terms of biology, but in the breadth of engineering. We also review the role of important organizations and conferences in the growth of BME, special features of BME education, first placements of BME graduates, and a few challenges to address in the future.

Core Competencies for Undergraduates in Bioengineering and Biomedical Engineering: Findings, Consequences, and Recommendations.

This paper provides a synopsis of discussions related to biomedical engineering core curricula that occurred at the Fourth BME Education Summit held at Case Western Reserve University in Cleveland, Ohio in May 2019. This summit was organized by the Council of Chairs of Bioengineering and Biomedical Engineering, and participants included over 300 faculty members from 100+ accredited undergraduate programs. This discussion focused on six key questions: QI: Is there a core curriculum, and if so, what are its components? QII: How does our purported core curriculum prepare students for careers, particularly in industry? QIII: How does design distinguish BME/BIOE graduates from other engineers? QIV: What is the state of engineering analysis and systems-level modeling in BME/BIOE curricula? QV: What is the role of data science in BME/BIOE undergraduate education? QVI: What core experimental skills are required for BME/BIOE undergrads? s. Indeed, BME/BIOI core curricula exists and has matured to emphasize interdisciplinary topics such as physiology, instrumentation, mechanics, computer programming, and mathematical modeling. Departments demonstrate their own identities by highlighting discipline-specific sub-specialties. In addition to technical competence, Industry partners most highly value our students' capacity for problem solving and communication. As such, BME/BIOE curricula includes open-ended projects that address unmet patient and clinician needs as primary methods to prepare graduates for careers in industry. Culminating senior design experiences distinguish BME/BIOE graduates through their development of client-centered engineering solutions to healthcare problems. Finally, the overall BME/BIOE curriculum is not stagnant-it is clear that data science will become an ever-important element of our students' training and that new methods to enhance student engagement will be of pedagogical importance as we embark on the next decade.

Birdcage volume coils and magnetic resonance imaging: a simple experiment for students.

BACKGROUND: This article explains some simple experiments that can be used in undergraduate or graduate physics or biomedical engineering laboratory classes to learn how birdcage volume radiofrequency (RF) coils and magnetic resonance imaging (MRI) work. For a clear picture, and to do any quantitative MRI analysis, acquiring images with a high signal-to-noise ratio (SNR) is required. With a given MRI system at a given field strength, the only means to change the SNR using hardware is to change the RF coil used to collect the image. RF coils can be designed in many different ways including birdcage volume RF coil designs. The choice of RF coil to give the best SNR for any MRI study is based on the sample being imaged. RESULTS: The data collected in the simple experiments show that the SNR varies as inverse diameter for the birdcage volume RF coils used in these experiments. The experiments were easily performed by a high school student, an undergraduate student, and a graduate student, in less than 3 h, the time typically allotted for a university laboratory course. CONCLUSIONS: The article describes experiments that students in undergraduate or graduate laboratories can perform to observe how birdcage volume RF coils influence MRI measurements. It is designed for students interested in pursuing careers in the imaging field.

Web-based neuromuscular simulator applied to the teaching of principles of neuroscience

INTRODUCTION: The learning of core concepts in neuroscience can be reinforced by a hands-on approach, either experimental or computer-based. In this work, we present a web-based multi-scale neuromuscular simulator that is being used as a teaching aid in a campus-wide course on the Principles of Neuroscience. METHODS: The simulator has several built-in individual models based on cat and human biophysics, which are interconnected to represent part of the neuromuscular system that controls leg muscles. Examples of such elements are i) single neurons, representing either motor neurons or interneurons mediating reciprocal, recurrent and Ib inhibition; ii) afferent fibers that can be stimulated to generate spinal reflexes; iii) muscle unit models, generating force and electromyogram; and iv) stochastic inputs, representing the descending volitional motor drive. RESULTS: Several application examples are provided in the present report, ranging from studies of individual neuron responses to the collective action of many motor units controlling muscle force generation. A subset of them was included in an optional homework assignment for Neuroscience and Biomedical Engineering graduate students enrolled in the course cited above at our University. Almost all students rated the simulator as a good or an excellent learning tool, and approximately 90% declared that they would use the simulator in future projects. CONCLUSION: The results allow us to conclude that multi-scale neuromuscular simulator is an effective teaching tool. Special features of this free teaching resource are its direct usability from any browser (http://remoto.leb.usp.br/), its user-friendly graphical user interface (GUI) and the preset demonstrations.

A inserção da engenharia biomédica nos cursos de graduação de engenharia elétrica no Brasil / The insertion of biomedical engineering in electrical engineering undergraduate courses in Brazil

A inserção de temas específicos da Engenharia Biomédica (EB) nos cursos de graduação em Engenharia Elétrica (EE) foi examinada em levantamento da oferta de disciplinas nesta área, realizado nos 214 cursos de EE que possuem dados sobre as grades curriculares e disciplinas em seus sítios na internet. Foram levantadas informações sobre os cursos de pós-graduação (PG) em EB existentes no Brasil, relacionadas à oferta de disciplinas de EB na graduação. Nossos dados indicam que apenas 7,5% dos cursos de EE examinados possuem pelo menos uma disciplina de EB, concentrados nas escolas públicas (87,5%) e nas regiões sul e sudeste do país (75%). Nestes poucos cursos, foram identificadas 40 disciplinas de EB. Apenas 11 delas oferecem introdução geral aos diferentes aspectos da área; os 3/4 restantes restringem-se a aspectos específicos de subáreas da EB. Além disso, 87,5% destas disciplinas são de caráter eletivo (ou não-obrigatório), com abordagem exclusivamente teórica dos temas (14,0% do total de horas-aula nas disciplinas de EB). Dos 10 programasde PG em EB, 60,0% estão em IES cujos cursos de EE possuem disciplinas específicas EB; 62,5% das disciplinas de EB são oferecidas por IES que não têm programas de PG na área, indicando pouca correlação entre a existência de um programa de PG em EB e a oferta de conteúdos nesta área para a graduação em EE. Estes dados sugerem a necessidade de inserção mais substancial e estruturada de temas de EB nos cursos de graduação em EE, em especial nas instituições privadas de ensino, e de estímulo a uma maior contribuição dos programas de PG no ensino de graduação em EE.

The present study surveyed the disciplines on Biomedical Engineering (BE) offered in 214 Electrical Engineering (EE) undergraduate courses in Brazilian Universities. Data on discipline content and other characteristics, as well as their association with graduate courses, were gathered from Internet sites in August and September, 2007. Our data indicate that only 7.5% of the Brazilian EE courses present at least one discipline on EB themes, greatly concentrated in public institutions and in the more developed south/southeast states. In only 25% of these few courses there are introductory disciplines presenting most of the different EB areas. In the remaining courses, only specific aspects of particular EB areas are presented in a fragmentary, isolated and non contextualized way. Furthermore, 87.5% of these EB disciplines are optional in the curriculium, and practical classes or approaches were offered in only 14% of the total class schedule. While 62.5% of the EB disciplines are offered by institutions that have graduating courses in EB, only 60% of the Brazilian graduation courses are involved in undergraduate EB disciplines. These data point to the need of a more structured and intensive inclusion of EB themes in the undergraduate courses (particularly in private institutions), as well as to the importance of a closer involvement of graduate courses in undergraduate instruction.
