Biomedical Engineering Literature: Advanced Reading Skills for Research and Practice

Medical engineering is a field of study that combines biological and medical sciences with engineering to develop improved healthcare technologies. It is imperative that you possess a deep understanding of both the material and the technical language used in this rapidly advancing field in order to effectively grasp key topics and navigate the rapidly expanding literature. This paper examines the future of the biomedical engineering profession through the lens of advanced reading strategies. It starts with the assertion that biomedical engineering literature presents three challenges: the level of density is technical, the area is interdisciplinary, and the growth of knowledge is exponential. In the view of the above challenges, the paper discusses various advanced reading skills in relation to biomedical engineers. These skills include the ability to critically read scientific texts, both at a fast pace for an overview and in detail for deeper understanding, to identify key ideas and methodologies relevant to the field, and to assess the validity of scientific claims and data representations. The paper also aims at pointing out how separate elements like the use of systematic reviews, of meta-analysis, of data visualization tools that complement reading, help the researcher in the process of managing gathered information from various sources. This paper describes teaching these skills for both academic and professional practice, with examples of how improved reading competencies can enhance research quality and contribute to innovations in medical technologies, tissue engineering, and clinical trials. Furthermore, the paper aims to discuss the future trends due to the increasing incorporation of continuous learning for addressing the challenges posed by novel technologies including artificial intelligence and nanotechnology that define the future of biomedical engineering. biomedical engineering students require the acquisition of higher order reading skills in preparation for information reading: national and international publications in the engineering profession, policy and technology in support of health care delivery systems, product development, and other purposes. The ideas stated and demonstrated in this paper should be practical to both beginning scholars and veteran professionals in the biomedical engineering field as well as useful for seminar and workshop participants in seminars and workshops on biomedical engineering literature.

Monitoring Metacognitive Strategies Use During Interaction Collaborative Groups

This study of the use of metacognitive strategies during learning interaction in collaborative groups is considered referential for understanding the development of such strategies. The use of metacognitive strategies is related to better learning outcomes. We monitored the interaction in five collaborative groups at three points in time (initial, intermediate and final). These groups consisted of undergraduate health science (n = 9) and biomedical engineering students (n = 10). The aims were the following: (1) To check whether there were significant differences in the use of metacognitive strategies between the groups of students monitored depending on the type of degree or the point in time measurement. (2) To test whether there were significant differences in students’ learning outcomes depending on whether or not they had participated in the interaction monitoring during collaborative interaction. (3) To test clustering without a pre-assignment variable against learning outcomes in collaborative groups. Significant differences were detected in the use of some of the metacognitive strategies of orientation, planning and elaboration in favor of the collaborative groups of the biomedical engineering students. Also, students who participated in monitoring collaborative groups in both clusters obtained better learning outcomes. Lastly, the assignment groups were exactly related to the collaboration groups with respect to the use of metacognitive strategies in the final measurement.

Analysing Virtual Labs Through Integrated Multi-Channel Eye-Tracking Technology: A Proposal for an Explanatory Fit Model

This study deals with an analysis of the cognitive load indicators produced in virtual simulation tasks through supervised and unsupervised machine learning techniques. The objectives were (1) to identify the most important cognitive load indicators through the use of supervised and unsupervised machine learning techniques; (2) to study which type of task presentation was most effective at reducing the task’s intrinsic load and increasing its germane load; and (3) to propose an explanatory model and find its fit indicators. We worked with a sample of 48 health sciences and biomedical engineering students from the University of Burgos (Spain). The results indicate that being able to see the task before performing it increases the germane load and decreases the intrinsic load. Similarly, allowing students a choice of presentation channel for the task respects how they process information. In addition, indicators of cognitive load were found to be grouped into components of position, speed, psychogalvanic response, and skin conductance. An explanatory model was proposed and obtained acceptable fit indicators.

An Introduction to Ventra: A Programmable Abdominal Phantom for Training, Educational, Research, and Development Purposes.

Intra-abdominal pressure (IAP) is a critical parameter in the care of critically ill patients, as elevated IAP can lead to reduced cardiac output and organ perfusion, potentially resulting in multiple organ dysfunction and failure. The current gold standard for measuring IAP is an indirect technique via the bladder. According to the Abdominal Compartment Society's Guidelines, new measurement methods/devices for IAP must be validated against the gold standard. This study introduces Ventra, an abdominal phantom designed to simulate different IAP levels, abdominal compliance, respiration-related IAP variations, and bladder dynamics. Ventra aims to facilitate the development and validation of new IAP measurement devices while reducing reliance on animal and cadaveric studies. Additionally, it offers potential applications in training and education for biomedical engineering students. This study provides a thorough explanation on the phantom's design and fabrication, which provides a low-cost solution for advancing IAP measurement research and education. The design concept, technical aspects, and a series of validation experiments determining whether Ventra is a suitable tool for future research are presented in this study. Ventra's performance was evaluated through a series of validation tests using a pressure gauge and two intra-gastric (Spiegelberg and CiMON) and two intra-bladder (Accuryn and TraumaGuard) pressure measurement devices. The mean and standard deviation of IAP recordings by each device were investigated. Bland-Altman analysis was used to evaluate bias, precision, limits of agreement, and percentage error for each system. Concordance analysis was performed to assess the ability of Ventra in tracking IAP changes. The phantom demonstrated excellent agreement with reference pressure measurements, showing an average bias of 0.11 ± 0.49 mmHg. A concordance coefficient of 100% was observed for the phantom as well. Ventra accurately simulated different abdominal compliances, with higher IAP values resulting in lower compliance. Abdominal volume changes showed a bias of 0.08 ± 0.07 L/min, and bladder fill volume measurements showed an average difference of 0.90 ± 4.33 mL for volumes ranging from 50 to 500 mL. The validation results were in agreement with the research guidelines of the world abdominal society. Ventra is a reliable tool that will facilitate the development and validation of new IAP measurement devices. It is an effective educational tool for biomedical engineering students as well.

Implementing a challenge-based learning experience in a bioinstrumentation blended course

BackgroundBioinstrumentation is essential to biomedical engineering (BME) undergraduate education and professional practice. Several strategies have been suggested to provide BME students with hands-on experiences throughout the curriculum, promoting their preparedness to pursue careers in industry and academia while increasing their learning and engagement. This paper describes the implementation of challenge-based learning (CBL) in an undergraduate bioinstrumentation blended course over the COVID-19 pandemic.MethodsThe CBL experience was implemented in a third-year bioinstrumentation course from the BME program at Tecnologico de Monterrey. Thirty-nine students enrolled in two sections formed fourteen teams that tackled blended learning activities, including online communication, lab experiments, and in-person CBL activities. Regarding the latter, students were challenged to design, prototype, and test a respiratory or cardiac gating device for radiotherapy. An institutional student opinion survey was used to assess the success of our CBL implementation.ResultsStudent responses to the end-of-term survey showed that they strongly agreed that this course challenged them to learn new concepts and develop new skills. Furthermore, they rated the student-lecturer interaction very positively despite the blended format. Overall, students assessed their learning experience positively. However, implementing this CBL experience required a substantial time increase in planning, student tutoring, and constant communication between lecturers and the industry partner.ConclusionThis work provides an effective instance of CBL for BME education to improve students’ learning experience despite decreased resource efficiency. Our claim is supported by the student’s performance and the positive feedback from our industrial partner.

Integration of Febio as an Instructional Tool in the Undergraduate Biomechanics Curriculum.

Computer simulations play an important role in a range of biomedical engineering applications. Thus, it is important that biomedical engineering students engage with modeling in their undergraduate education and establish an understanding of its practice. In addition, computational tools enhance active learning and complement standard pedagogical approaches to promote student understanding of course content. Herein, we describe the development and implementation of learning modules for computational modeling and simulation (CM&S) within an undergraduate biomechanics course. We developed four CM&S learning modules that targeted predefined course goals and learning outcomes within the febio studio software. For each module, students were guided through CM&S tutorials and tasked to construct and analyze more advanced models to assess learning and competency and evaluate module effectiveness. Results showed that students demonstrated an increased interest in CM&S through module progression and that modules promoted the understanding of course content. In addition, students exhibited increased understanding and competency in finite element model development and simulation software use. Lastly, it was evident that students recognized the importance of coupling theory, experiments, and modeling and understood the importance of CM&S in biomedical engineering and its broad application. Our findings suggest that integrating well-designed CM&S modules into undergraduate biomedical engineering education holds much promise in supporting student learning experiences and introducing students to modern engineering tools relevant to professional development.

Phenomenological Evaluation of an Undergraduate Clinical Needs Finding Skills Through a Virtual Reality Clinical Immersion Platform

Clinical immersion programs have been widely used in higher education, particularly in biomedical engineering (BME) programs, to allow students to identify and evaluate the unmet clinical needs. However, due to limited space and extensive safety protocols required to enter hospitals, access for undergraduate students to shadow physicians is limited. BME students need to be trained to identify and evaluate unmet clinical needs through observation and experience to remain competitive in the medical device landscape. To be able to allow students to immerse themselves into clinical environments remotely and be able to visualize the full spectrum of healthcare workers and equipment that support a procedure beyond what is available through online video records, we have developed a virtual reality (VR) clinical immersion platform. The applicability and overall student satisfaction of using VR learning environments was investigated through a pilot undergraduate BME unmet clinical needs finding course in the spring of 2022. Pre- and post-course survey analyses revealed that the VR clinical immersion experiences did greatly increase immersion within a medical procedure, and students felt sensations of presence and embodiment. Given the results of this study, VR learning environments can provide a means for students to perform unmet clinical needs through virtual clinical immersion. However, these technologies to support environments should be readily accessible within the classroom.

Determinants of Intra-major Specialization and Career Decisions Among Undergraduate Biomedical Engineering Students

Biomedical engineering is a broad and interdisciplinary field that prepares graduates for a variety of careers across multiple career sectors. Given this breadth, undergraduate degree programs often have formal or informal opportunities for students to further specialize within the biomedical engineering major to develop skills in subdisciplines of biomedical engineering. While previous work has explored factors that influence student decision-making of engineering major choice, including the role of gender, limited work has explored factors that influence intra-major specialization in biomedical engineering. The present study sought to expand on existing research to understand factors that influence biomedical engineering students’ choice of intra-major specializations and how, if at all, these factors are related to gender. Grounded in social cognitive career theory, the present study leveraged quantitative surveys from undergraduate biomedical engineering students to understand factors influencing intra-major specialization choice, including the impact that students viewed on their career plans. Participants rated multiple factors as important in their intra-major specialization decisions, with professors/classes rated as the most important influence and alumni as the lowest. Similarly, participants rated multiple outcome expectations of their specialization, although income was rated lower than other factors. Participants most commonly indicated interest in pursuing careers in industry and medicine. We found some differences in intra-major specialization, outcome expectations, and career interests by gender, with women students indicating a higher influence of professors/classes and higher expectations for their track decision to provide a career with a good income. Further understanding of how undergraduate students select specializations in engineering coursework will inform curriculum design and student advising.

Awareness and level of digital literacy among students receiving health-based education

BackgroundBeing digitally literate allows health-based science students to access reliable, up-to-date information efficiently and expands the capacity for continuous learning. Digital literacy facilitates effective communication and collaboration among other healthcare providers. It helps to navigate the ethical implications of using digital technologies and aids the use of digital tools in managing healthcare processes. Our aim in this study is to determine the digital literacy level and awareness of our students receiving health-based education in our university and to pave the way for supporting the current curriculum with courses on digital literacy when necessary.MethodStudents from Acibadem University who were registered undergraduate education for at least four years of health-based education, School of Medicine, Nutrition and Dietetics, Nursing, Physiotherapy and Rehabilitation, Psychology, Biomedical Engineering, Molecular Biology, and Genetics were included. The questionnaire consisted of 24 queries evaluating digital literacy in 7 fields: software and multimedia, hardware and technical problem solving, network and communication/collaboration, ethics, security, artificial intelligence (A.I.), and interest/knowledge. Two student groups representing all departments were invited for interviews according to the Delphi method.ResultsThe survey was completed by 476 students. Female students had less computer knowledge and previous coding education. Spearman correlation test showed that there were weak positive correlations between the years and the “software and multimedia,” “ethics,” “interest and knowledge” domains, and the average score. The students from Nursing scored lowest in the query after those from the Nutrition and Dietetics department. The highest scores were obtained by Biomedical Engineering students, followed by the School of Medicine. Participants scored the highest in “network” and “A.I.” and lowest in “interest-knowledge” domains.ConclusionIt is necessary to define the level of computer skills who start health-based education and shape the curriculum by determining which domains are weak. Creating an educational environment that fosters females’ digital knowledge is recommended. Elective courses across faculties may be offered to enable students to progress and discuss various digital literacy topics. The extent to which students benefit from the digital literacy-supported curriculum may be evaluated. Thus, health-based university students are encouraged to acquire the computer skills required by today’s clinical settings.RegistrationThis study was approved by Acıbadem University and Acıbadem Healthcare Institutions Medical Research Ethics Committee (ATADEK) (11 November 2022, ATADEK registration: 2022-17-138) All methods were carried out in accordance with relevant guidelines and regulations. Informed consent was obtained from the participants.

Creation of a Novel 3D-Printed Amniocentesis Simulation Model and Impact on Resident Confidence

Background: Non-invasive prenatal screening has decreased opportunities for diagnostic antenatal procedures during residency training. Commercially available models are often cost prohibitive while homemade models can be low fidelity and non-reusable. Objective: To create a training tool with realistic anatomy, tissue-specific tactile sensation, and cost-effective assembly for amniocentesis procedural technique practice and evaluate its impact on trainee confidence with performance. Study Design: Collaborating with biomedical engineering students, our team defined several characteristics to achieve a high-fidelity model: compatible with ultrasound, anatomically accurate, demonstrate tactile realism, endure repeat use, and be cost-effective. A 3-D printed model was created that satisfied fidelity guidelines after rigorous materials and imaging testing. Results: We implemented the model in the observed structured clinical exam for Obstetrics and Gynecology residents in which trainees (PGY2-4) performed an amniocentesis after guided practice with Maternal-Fetal Medicine faculty. Residents were given pre and post-simulation Likert scale surveys regarding confidence and satisfaction with the model. Descriptive analyses and paired t-test were used for analysis. 19 residents completed both pre and post surveys. Mean resident confidence in performing an amniocentesis increased from 1.6 to 3.2 (p<0.001, scale 1-5) after the practice session. Most residents (89.5%) strongly agreed that the model was easy to use and would use it to practice independently. Conclusion: This novel 3-D printed, ultrasound compatible, anatomically accurate, and cost-effective amniocentesis model provides high-fidelity procedural practice and improved trainee confidence. Models such as these have the potential to greatly impact skill development for rare procedures. Future directions include modifying this model for additional fetal procedures, such as cordocentesis.

Training and education of young physicians and engineers in the field of endoscopy and laparoscopy – a review of Germany-wide joint cooperation and training possibilities

Abstract Introduction: Application-related (hands-on) training and instruction is an essential component in the advanced education of physicians in residency. To teach and train required endoscopic examinations and interventions in a standardized manner, courses are offered by various societies. Within these courses the assistant endoscopists learn and train how to use the technical equipment and how to perform the examinations and related interventions. Similarly, for graduate biomedical engineering students with a job- or research-related interest in the field of endoand laparoscopy, an early involvement and practical introduction to the instrumentation and techniques - if possible already during their studies - can generate a fundamental understanding of the technical requirements as well needs of the physicians. Objective: As various such (hands-on) training-courses for flexible and rigid endoscopy specifically addressing young physicians, surgeons as well as engineers are offered by numerous institutes, this contribution tries do provide a structured overview on/over these possibilities. Material: Known cross-institutional courses in the field of endo- and laparoscopy currently offered in Germany in cooperation of physicians and engineers are listed and briefly described. Results: A total of n = 4 crossinstitutional courses for the introduction and training in flexible and rigid endoscopy have been identified. Discussion: The cross-institutional courses for physicians and technicians in the field of endo- and laparoscopy presented serve to provide a better understanding of the subject matter and the field of either discipline. Questions that arise in the field of endoscopy from physicians can be addressed at an early stage and, if necessary, worked on with little effort. Ideas for new instruments and even new interventions can arise and be pursued through an intensive exchange between technicians and physicians. Collaborations are established on a local basis which will foster national activities in this field and which allow to develop competencies relevant for the industrial sector of medical engineering.

Identifying Supports and Barriers in Engineering Students’ Processes Toward Career Attainment

Evidence shows that biomedical engineering students face unique challenges in entering the workforce compared to peers in other engineering majors. The purpose of this study is to explore the factors impacting undergraduate engineering students’ career attainment, or the acquisition of employment in a chosen field, and how the students experienced these factors in their pathways towards post-graduate employment. By studying differences in processes towards career attainment, there is an opportunity to promote equity and better support the inclusion and persistence of women and racially minoritized groups in engineering, particularly their readiness to enter the engineering workforce. We sought to answer two research questions: (RQ1) What contextual factors are identified by engineering students as supports and barriers to their attainment of a career in the engineering field? (RQ2) How are engineering students experiencing inequities in their processes toward career attainment? We conducted six focus groups with undergraduate engineering students at a large Midwestern University. Participants were purposefully sampled based on demographics from four engineering disciplines: biomedical engineering and the three preferred majors for students transferring out of biomedical engineering at our university, chemical engineering, materials science and engineering, and mechanical engineering. We used social cognitive career theory (SCCT) to inform our data collection and analysis and interpret the findings. The transcripts were analyzed by developing a codebook containing theory-driven codes from SCCT and emergent codes from the data. We identified five themes representing the contextual factors impacting engineering students’ processes toward career attainment: implications of (1) interpersonal relationships; (2) institutional infrastructure; (3) academics; (4) social identity; and (5) out-of-class experiences. We also found that these contextual factors may act as either a support or barrier depending on personal factors such as demographics, personality, or identity. The nuance revealed in this study, that a contextual factor may be both a support and barrier, presents implications for universities to provide more individualized career preparedness resources and recognize the ways that students’ positionalities impact their processes toward career attainment.

Perception of Biomedical Engineering Students' Contribution to Course Projects During Pandemic.

One of the main challenges in the team-based project assessment is to evaluate the student's individual contributions, especially when the students work remotely during the Covid-19 pandemic. In this study, the student's perception of their teammates' contribution to the course project will be examined. This study will focus on assessing the soft skills aspect, such as the student's role, commitment, responsibility and awareness in a team. 42 students that are participated in the course will fill out an end-semester questionnaire. In general, students assess themselves in a more lenient than their teammates. Furthermore, the students tend to have a low profile in assessing themselves. It can be interpreted that they tend to have low self-confidence about their role in a team. Therefore, the results of this study can be used to improve the course project implementation, especially to assist the students in having higher confidence in their ability, capability and role in a group-based project. In addition, this study also shows that the instructor should not only rely on student peers' assessment and self-assessment.

Biomedical Engineering Students’ Perceived Learning Through Co-Curriculars

Background: Co-curricular student outcomes research has focused on connecting outcomes to activities based on the co-curricular type. Less work has explored what aspects of those co-curricular activities could lead to student outcomes. Purpose: Our research aimed to identify common elements of co-curricular activities that connected to students’ development of professional, career, or personal outcomes and can inform how we study and design co-curricular activities in engineering. Design: We recruited participants from one biomedical engineering (BME) program. We used a one-year series of four semi-structured interviews with fourteen upper-level BME students to explore students’ perceptions of their co-curricular learning. Using a qualitative, causal analysis approach, we identified elements of students’ co-curricular experiences in research or a multi-disciplinary design team, as well as other co-curricular experiences (e.g., internships, professional societies), that linked to professional, career, or personal learning outcomes that have been previously identified as important in engineering education. Findings: We identified patterns of connections between unique “experience elements” and a variety of “outcome categories” through participant activities we called “participant actions.” The most prevalent connections—those experience elements and participant actions that connected to multiple outcome categories—included the experience elements Independent Project Work, Project Work That Engages Multiple Disciplines, STEM Education Opportunities, and Mentorship from a Skilled Other as well as a participant action Reflecting on Experience. We found connections to the outcome categories of Leadership, Design, Business, Interdisciplinary Competence, Disciplinary Competence, Communication, and Career Direction Outcomes. Conclusions: Based on our findings, educators and mentors should consider the value of supporting students’ decision-making autonomy and multidisciplinary interactions in projects to support learning. They could also incorporate opportunities for students to teach each other technical content, receive structured mentorship, and reflect on their experiences as they are happening. Further, this work demonstrates a need to explore co-curricular learning processes in new ways that can lead to better understandings of students’ learning processes.

Application Research and Prospect of 3D Modeling, Printing Medical Course Teaching Aids

Background: The application of 3D printing technology in the field of education is mainly concentrated on the curriculum of primary and secondary schools and clinical PBL teaching, while the application of 3D printing technology as a teaching auxiliary means in higher medical education is less. Methods: The objective of this work is to demonstrate the use of 3D printing teaching aids to improve students' learning outcomes and guide more students to participate in learning 3D printing or biological 3D printing research. Based on 3D printing technology, data were collected through a network questionnaire to analyze the demand of medical students in Colleges and Universities in this paper for 3D printing teaching aids. Through the demand for 3D printing teaching aids, we have offered 3D courses and encouraged students to actively participate in model design. Results: Students can print some models using a 3D printer based on their knowledge and personal interests. It is found that universities can use virtual 3D printing technology to make up for the current shortage of 3D printers and high material consumption. Conclusion: 3D printing technology can also help biomedical engineering students better combine clinical knowledge to achieve better results. In addition, this study also analyzed the limitations of 3D printing development in China.

An Examination of the Effects of Virtual Reality Training on Spatial Visualization and Transfer of Learning.

Spatial visualization ability (SVA) has been identified as a potential key factor for academic achievement and student retention in Science, Technology, Engineering, and Mathematics (STEM) in higher education, especially for engineering and related disciplines. Prior studies have shown that training using virtual reality (VR) has the potential to enhance learning through the use of more realistic and/or immersive experiences. The aim of this study was to investigate the effect of VR-based training using spatial visualization tasks on participant performance and mental workload using behavioral (i.e., time spent) and functional near infrared spectroscopy (fNIRS) brain-imaging-technology-derived measures. Data were collected from 10 first-year biomedical engineering students, who engaged with a custom-designed spatial visualization gaming application over a six-week training protocol consisting of tasks and procedures that varied in task load and spatial characteristics. Findings revealed significant small (Cohen's d: 0.10) to large (Cohen's d: 2.40) effects of task load and changes in the spatial characteristics of the task, such as orientation or position changes, on time spent and oxygenated hemoglobin (HbO) measures from all the prefrontal cortex (PFC) areas. Transfer had a large (d = 1.37) significant effect on time spent and HbO measures from right anterior medial PFC (AMPFC); while training had a moderate (d = 0.48) significant effect on time spent and HbR measures from left AMPFC. The findings from this study have important implications for VR training, research, and instructional design focusing on enhancing the learning, retention, and transfer of spatial skills within and across various VR-based training scenarios.

Lessons from Developing Multimedia Learning Materials for the Digital Generation

Recognizing that traditional textbooks on need-driven health technology innovation were increasingly misaligned with the needs of today’s undergraduate biomedical engineering students and the faculty who teach them, we initiated an effort to develop new learning materials for this audience. To guide our efforts, we conducted literature searches on best practices in the development of online content and engaging digital learners (primarily Gen-Z). We further held a series of discussions with biomedical engineering students and instructors at universities across the United States. This input led us to the development of a set of modular, online, multimedia learning materials specifically designed for the new generation of undergraduate learners. In this article, we present the key decisions that helped shape the project. We also share the results of feedback surveys and focus groups that shed light on how the materials have been preliminarily received. Finally, we reflect on challenges, opportunities, and lessons from this project that may be helpful to other initiatives focused on the creation of multimedia content for the digital generation.

Early introduction of 3D modeling modules promotes the development of simulation skills in downstream biomedical engineering curricula

BackgroundRecent advancements in additive manufacturing have made 3D design a desirable skill in combating the historically slow development of biomedical products. Due to the broad applicability of additive manufacturing to biomedical engineering, 3D design and 3D printing are attractive educational tools for biomedical engineering students. However, due to the multidisciplinary nature of biomedical engineering, finding a suitable spot in the curriculum to teach students basic and application-based skills for 3D manufacturing is difficult. Furthermore, prior training in fundamental 3D design skills may be needed to support the use of application-based supplementary content.ResultsWe designed a SolidWorks Simulations toolkit to complement a sophomore (2nd-year)-level Biomechanics course and distributed this assignment to students with and without prior training in 3D design delivered in an introductory biomedical engineering course. Using short videos, example-based problem solving, and step-by-step tutorials, students completed this as an extra-credit assignment and completed a survey gauging student opinion on SolidWorks and 3D design, confidence in each target skill, and the effectiveness of assignment delivery. The compilation of survey responses suggests that the assignment effectively increased positive responses in student opinion on interest in and likeliness to use SolidWorks in both groups. However, confidence in the target assignment skills was higher in the trained group and fewer problems occurred in operating SolidWorks for trained students. Further, analyzing the distribution of student grades with respect to survey responses suggests that responses had no relationship with initial class grade.ConclusionThese data collectively indicate that prior training provided to the students had a positive impact on the effectiveness of the assignment although increases in student opinion on the utility of 3D design were observed in both trained and untrained students. Our work has generated and identified a useful educational supplement to enrich existing biomedical engineering course materials with practical skills.
