Efficacy of virtual reality and augmented reality in anatomy education: A systematic review and meta-analysis.

Anatomy is the cornerstone of medical education. Virtual reality (VR) and augmented reality (AR) technologies are becoming increasingly popular in the development of anatomy education. Various studies have evaluated VR and AR in anatomy education. This meta-analysis aims to evaluate the effectiveness of VR and AR in anatomical education. The protocol was registered in Prospero. Scopus, PubMed, Web of Science, and Cochrane Library databases were searched. From the 4487 articles gathered, 24 randomized controlled trials were finally selected according to inclusion criteria. According to the results of the meta-analysis, VR had a moderate and significant effect on the improvement of knowledge scores in comparison with other methods (standardized mean difference = 0.58; 95% CI = 0.22, 0.95; p < 0.01). Due to the high degree of heterogeneity (I2 = 87.44%), subgroup analyses and meta-regression were performed on eight variables. In enhancing the "attitude," VR was found to be more "useful" than other methods (p = 0.01); however, no significant difference was found for "enjoyable" and "easy to use" statements. Compared with other methods, the effect of AR on knowledge scores was non-significant (SMD = -0.02; 95% CI = -0.39, 0.34; p = 0.90); also, in subgroup analyses and meta-regression, the results were non-significant. The results indicate that, unlike AR, VR could be used as an effective tool for teaching anatomy in medical education. Given the observed heterogeneity across the included studies, further research is warranted to identify those variables that may impact the efficacy of VR and AR in anatomy education.

Learning in context: Undergraduate students' knowledge and the content retention of anatomy between discipline-specific and integrated course approaches.

Undergraduate introductory human anatomy and human physiology courses are either taught as discipline-specific or integrated anatomy and physiology (A&P) sequences. An institution underwent a curricular revision to change the course approach from discipline-specific Human Anatomy and Human Physiology to an integrated A&P I and II sequence, allowing the unique opportunity to explore the potential role of contextual learning in academic achievement and content retention. Mediation and moderation analysis was used to evaluate lecture examinations, laboratory practical examinations, and anatomical content retention between the different course approaches. Undergraduate students in the integrated A&P I course approach performed significantly better on lecture assessments and had a higher anatomy content retention rate at the end of the year than students enrolled in the standalone Human Anatomy course. The lecture examination averages between Human Physiology and A&P II (the second course in the sequence), as well as the anatomy laboratory practical examinations, were not significantly different between discipline-specific and integrated course approaches. The results suggest contextual learning-providing physiological context to anatomical structures-increases the anatomical content retention and academic achievement overall.

"My Dead Body": Development, production, and reception of a documentary that publicly displays the dissection of a human donor.

Recently, there has been an emphasis on keeping the study of anatomy using donor material confined to the domain of medical and allied healthcare professionals. Given the abundance of both accurate and inaccurate information online, coupled with a heightened focus on health following the COVID-19 pandemic, one may question whether it is time to review who can access learning anatomy using donors. In 2019, Brighton and Sussex Medical School (BSMS) obtained a Human Tissue Authority Public Display license with the aim of broadening the reach of who could be taught using donor material. In 2020, BSMS received its first full-body donor with consent for public display. Twelve workshops were delivered to student groups who do not normally have the opportunity to learn in the anatomy laboratory. Survey responses (10.9% response rate) highlighted that despite being anxious about seeing inside a deceased body, 95% felt more informed about the body. A documentary "My Dead Body" was filmed, focusing on the rare cancer of the donor Toni Crews. Viewing figures of 1.5 million, and a considerable number of social media comments highlighted the public's interest in the documentary. Thematic analysis of digital and social media content highlighted admiration and gratitude for Toni, the value of education, and that while the documentary was uncomfortable to watch, it had value in reminding viewers of life, their bodies, and their purpose. Fully consented public display can create opportunities to promote health-conscious life choices and improve understanding of the human body.

Persistence of changed attitudes among students in an integrated anatomy curriculum.

Many medical schools in the United States have integrated anatomy into an organ-based preclinical curriculum with some schools using anatomy as the cornerstone of their reorganization efforts. Curricular change could affect one or more of the three domains of learning, with the cognitive domain often scrutinized exclusively. A previous study reported the impact of anatomy integration on the affective domain, specifically, student attitudes toward learning anatomy. This mixed methods follow-up study asked if the observed attitudinal changes and lack of effect on student knowledge and confidence persisted using knowledge and confidence surveys, focus groups, internal and national surveys, and United States Medical Licensing Examination® performance metrics. Results evidenced the persistence of specific attitudinal differences between cohorts with blocked versus integrated anatomy with no apparent short- or long-term differences in anatomy learning or confidence in this learning. Altered attitudes included lower value placed on working in teams and reflective practices, and less recognition of anatomy's contribution (or less contribution of anatomy learning) to professional identity formation. These attitudinal changes could result in a weaker foundation for building collaborative skills throughout the medical curriculum. A decreased sense of student engagement also followed curricular change, as assessed by data from the American Association of Medical Colleges Year 2 Questionnaire. Overall, results emphasized the necessity of anticipating, monitoring, and if necessary, addressing changes in the affective domain when undertaking curricular change.

Comfort levels and experiences of middle school and high school age children in anatomical donor-based anatomy outreach sessions.

Many health professions schools host anatomy outreach sessions for high school students that utilize anatomical donors. However, teaching with anatomical donors for younger learners is uncommon. This study aimed to assess the comfort levels and experiences of students who attended the anatomy sessions as part of summer programs at Rutgers New Jersey Medical School. Younger learners (students entering grades 7-10; n = 25) and older learners (students entering grades 11-12; n = 33) completed pre- and post-session surveys about their comfort using a 5-point Likert scale. Before the sessions, most students felt comfortable or very comfortable learning from isolated organs (µ = 2.7, SD = 1.3) or full-body donors (µ = 2.4, SD = 1.4), even though most have never been to an anatomical donor lab before. After the sessions, the comfort level significantly increased for both isolated organs (µ = 3.3, SD = 1.1; p = 0.02) and full-body donors (µ = 3.1, SD = 1.2; p = 0.004). For isolated organs, there was no significant difference in the comfort level between younger and older learners before (p = 0.50) or after (p = 0.56) the sessions. Similarly, for full-body donors, there was no significant difference in the comfort level between younger and older learners before (p = 0.95) or after (p = 0.75) the sessions. Most students expressed that the experience was unique and positive. In conclusion, most students entering grades 7-12 felt comfortable learning from isolated organs and full-body anatomical donors prior to the sessions and felt more comfortable after the sessions. With this, anatomy outreach programs that utilize anatomical donors could be expanded to include younger learners to provide more dynamic teaching experiences for students of various ages.

Anatomical knowledge enhancement through echocardiography and videos, with a spotlight on cognitive load, self-efficacy, and motivation.

In recent years, there has been a growing recognition of the importance of integrating ultrasound into undergraduate medical curricula. However, empirical evidence is lacking as to its effect on anatomy learning and related student cognition. Therefore, the present study compared the impact of echocardiography-based instruction with narrated videos on students' understanding of anatomical relationships, as well as the interaction with students' autonomous motivation, self-efficacy beliefs, mental load, and attitudes. Second-year medical students were given the opportunity to enroll in a supplementary booster course about cardiac anatomy. On the base of a randomized controlled trial with a cross-over design, we studied the effect of taking this course on spatial anatomical knowledge. After completing a pre-test (T0), students were allocated randomly to either the echocardiography-based teaching condition (cohort A) or the narrated anatomy video condition (cohort B). Next, participants were crossed over to the alternative intervention. Immediately after each phase in the intervention, students were asked to rate their mental load. Additionally, a spatial anatomical knowledge test, an autonomous motivation scale, and a self-efficacy scale were administered before (T0) and after the first intervention (T1) and at the end of the study (T2). Finally, each student completed a perception-based survey. The study design allowed a comparative evaluation of both interventions at T1, while the cross-over design facilitated the assessment of the most optimal sequencing in the interventions at T2. A total of 206 students participated (cohort A: n = 99, cohort B: n = 107). At T1, no significant differences in the knowledge test and the autonomous motivation scale were observed between cohorts A and B. However, cohort A showed higher self-efficacy beliefs compared to cohort B (p = 0.043). Moreover, cohort A reported higher levels of perceived mental load (p < 0.001). At T2, the results showed that neither sequence of interventions resulted in significant differences in anatomy scores, autonomous motivation, or self-efficacy. However, a significant difference in mental load was found again, with students in cohort B reporting a higher level of mental load (p < 0.001). Finally, based on the perception-based survey, students reported favorably on the echocardiography experience. In conclusion, the hands-on echocardiography sessions were highly appreciated by the medical students. After participating in the ultrasound sessions, they reported higher levels of self-efficacy beliefs compared to the video-based condition. However, despite embodied cognition principles, students in the echocardiography condition did not outperform students in the narrated anatomy video condition. The reported levels of mental load in the ultrasound condition could explain these findings.

Living and post-mortem CT scans in the gross anatomy lab: A study investigating differences in first-year medical students' exam performance and perceptions.

Basic competency in radiological imaging is essential for physicians to identify and manage diseases. An optimal place in which to include imaging in the medical curriculum is during anatomy as students can correlate the 3D anatomy from their body donors with the 2D cross-sectional anatomy. The goal of this project was to enhance first-year medical students' knowledge of cross-sectional imaging in the gross anatomy lab and to investigate whether there are benefits to learning cross sectional imaging via scans from body donors versus living individuals. Student participant performance was evaluated on laboratory practical examinations, CT image questions and spatial anatomical knowledge in the thorax and abdomen sections of gross anatomy. Students learned the cross-sectional imaging during dissections where they accessed the images relevant to their study on Pacsbin, a web-based Digital Imaging and Communication in Medicine viewer, via iPads. Results showed no statistically significant differences in practical examination scores, spatial anatomical knowledge, or identification of anatomical structures on CT image questions between participants who learned from images on body donors versus living individuals. In a questionnaire given at the end of the course, participants cited that the CT images improved their anatomical and imaging knowledge and that they felt better prepared to use imaging software and interpret diagnostic imaging results upon entering clerkships. While there were no differences in academic performance between the groups, positive outcomes regarding student perceptions of anatomical and imaging knowledge and preparedness for use of imaging software were identified in this study.

Application of augmented reality models of canine skull in veterinary anatomical education.

Veterinary anatomy plays a crucial role in the curriculum for veterinary medicine and surgery. The integration of modern information technology in veterinary education can greatly benefit from innovative tools such as augmented reality (AR) applications. The aim of this study was to develop an accurate and interactive three-dimensional (3D) digital model of an animal skull using AR technology, aiming to enhance the learning of skull anatomy in veterinary anatomy education. In this study, a canine skull specimen was isolated, and the skull bones were scanned using a structured light scanner to create a 3D digital model of the canine skull, which was found to be indistinguishable from the original specimen by measurement of skull proportions. Furthermore, the interactive AR model of the canine skull, displayed using Unity3D, was subjected to testing and evaluation by 60 first-year veterinary medical students attending the gross anatomy of the animal. The students were divided into two groups: the traditional group and AR group. Both groups completed an objective test and a questionnaire. The evaluation of learning effectiveness in the test revealed no significant difference between the traditional group (which learned using textbooks and a canine skull specimen) and AR group (which learned using AR tools). However, in the questionnaire, students displayed high enthusiasm and interest in using the AR tool. Therefore, the application of AR tools can improve students' motivation for learning and enhance the comprehension of anatomical structures in three dimensions. Furthermore, this study exemplifies the use of AR as an auxiliary tool for teaching and learning in veterinary anatomy education.

Chinese anatomy educators' perceptions of blended learning in anatomy education: A national survey in the post-COVID-19 era.

Blended learning, which combines face-to-face lectures with online learning, has emerged as a suitable teaching approach during the COVID-19 pandemic. This study used a national survey of anatomy educators in Mainland China to evaluate the changes in the implementation of blended learning in anatomical pedagogy. A total of 297 responses were collected from medical schools across all provinces. Respondents included 167 males and 130 females, with an average age of 44.94 (±8.28) and average of 17.72 (±9.62) years of professional experience. The survey showed adoption of online teaching and assessment by Chinese anatomy educators increased by 32.7% and 46.8%, respectively, compared to pre-pandemic levels. Perceptions of blended learning outcomes varied, with 32.3% and 37% educators considering it superior and inferior to traditional teaching, respectively. Faculty training programs related to blended learning increased significantly, fostering a collaborative learning environment; however, challenges remained in achieving satisfactory online assessment outcomes. Anatomy educators' attitudes reflected a strong preference for classroom learning (4.941 ± 0.856) and recognition of the importance of relevant technology (4.483 ± 0.954), whereas online learning received lower acceptance (4.078 ± 0.734). Female anatomy teachers demonstrated effective time management in online teaching. Meanwhile, educators with over 15 years of experience encountered difficulties with relevant technology, consistent with negative attitudes toward blended learning. Overall, this survey highlights the persistent challenges in implementing blended learning in anatomy education and provides insights for enhancing the pedagogical model in the post-COVID-19 era.

Impact of gross anatomy laboratory on student written examination performance: A 3-year study of a large-enrollment undergraduate anatomy course.

The efficacy of the various pedagogies that are used in human anatomy laboratories has been extensively debated. Nevertheless, an important question remains relatively unexamined-how the learning experience in the anatomy laboratory impacts students' mastery and application of anatomical knowledge beyond the laboratory setting. In this study, the effect of a prosection-based anatomy laboratory on overall comprehension and mastery of anatomical knowledge was evaluated in an upper division undergraduate anatomy curriculum that consists of a mandatory lecture course and an optional laboratory course. This flexible curricular structure permitted assessing the merit of laboratory learning on the written examination performance of the lecture course. In 2019 and 2022, the anatomy laboratory was taught in-person using prosections, while in 2021 due to the Covid-19 pandemic related regulations, it was taught remotely with live-streaming of prosections using document cameras. In both in-person and remote instructive formats, written examination scores of the lecture course were compared between two cohorts of students: Those enrolled in lecture only and those enrolled in both lecture and laboratory. Results showed that the cohort enrolled in both lecture and laboratory courses consistently outperformed the lecture-only cohort by one full letter grade. Furthermore, when the degrees of improvement on written examination scores were compared between the two instructive formats, in-person laboratory had a greater increase compared to remote laboratory. Altogether this study demonstrates that the prosection-based anatomy laboratory enhances students' mastery of anatomical knowledge beyond the laboratory setting by promoting comprehension of spatial relationships of anatomical structures.

Constructive alignment: Teaching introductory gross anatomy to sport science students.

The purpose of this descriptive article was to illustrate the process of using constructive alignment in redesigning an introductory gross anatomy unit that is taught specifically to sports science and physical education students at Victoria University. The unit was redesigned as an intensive learning unit in 2017 as part of a broader university-wide process. The teaching team decided that the first stage of the constructive alignment process should be necessarily focused on an understanding of the career destinations of graduates from the courses. With this understanding, it became easier to work through the redesign of intended learning objectives, the shift from systemic to regional anatomy changes in content and learning support mechanisms, and alterations to assessment practices. A comparison of student pass rates for the unit from 2018 to 2023 with pass rates in the previous semester-long version of the unit, suggests optimism about the changes that were made through the constructive alignment process. However, there were a number of other factors that may have contributed to this result, and more research is needed on the specific effectiveness of the changes made during the constructive alignment process before a confident conclusion about the success of the process can be made.

The current state of anatomy education in United States doctor of physical therapy programs.

Physical therapy education has significantly evolved over the past few decades. While gross anatomy is integral to physical therapy education curricula, the current state of anatomy education within these programs is not well understood. The primary purpose of this report was to provide an update on the current state of anatomy education across United States (US) Doctor of Physical Therapy (DPT) programs. A survey was disseminated to all 261 accredited US physical therapy programs. The survey was deployed in November 2020 with a deadline to respond by January 15, 2021. The response rate was 32.6% (85/261). When teaching anatomy, 90.5% of the responding programs used dissection, 71.4% used didactic lectures, 60.7% used computer-assisted technology, 58% used prosections, 23.8% used plastinated models, and 31% reported using other methods. DPT programs have experienced declines in PhD faculty (15.7%) and Master of Physical Therapy faculty (15.3%) and notable increases in DPT (16.5%) and physician faculty (8.2%) teaching anatomy within DPT programs. Despite greater use of computer-assisted technologies, these technologies have not replaced donor-based dissection in DPT programs.

Evaluating knowledge loss over multiple retention intervals can identify deficiencies and inform curricular development.

Nursing students struggle to retain enough anatomical knowledge to meet their entry to practice competencies, but what knowledge is missing and when this occurs has been previously unexplored. A cohort of 80 nursing students were given multiple choice quizzes to assess their anatomical knowledge on 11 different organ systems during their second, third, and fourth year. Results were analyzed in comparison to their first-year examination scores to determine knowledge loss. Results showed an overall knowledge loss of 33.5% in the second year, 31.8% in the third year, and 29.6% in the fourth year. There were significant differences in system specific results. Special senses (i.e., audition) had a 20.6% loss in the second year, increased in retention to a 17.3% loss in third year, and then decreased to a 37% loss in fourth year. The vascular system had a 46.1% knowledge loss at the second-year assessment, declined to 49% knowledge loss in the third year, but improved to 27.6% knowledge loss by the fourth year. A similar change was observed for the musculoskeletal system with second-year loss at 30.7%, third-year loss at 40.3%, and fourth-year loss at 26.6%. These data suggest there are significant differences in the amount of knowledge retained by nursing students depending on the system being tested and the year the test is taken. Identifying the areas and times where anatomical knowledge is lost and gained is valuable for instructors in any program so that specific topics can be targeted at different times with more effective educational strategies.

Objects drawn from haptic perception and vision-based spatial abilities.

Haptic perception is used in the anatomy laboratory with the handling of three-dimensional (3D) prosections, dissections, and synthetic models of anatomical structures. Vision-based spatial ability has been found to correlate with performance on tests of 3D anatomy knowledge in previous studies. The objective was to explore whether haptic-based spatial ability was correlated with vision-based spatial ability. Vision-based spatial ability was measured in a study group of 49 medical graduates with three separate tests: a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRT A) and three (MRT C) dimensions and a Surface Development Test (SDT). Haptic-based spatial ability was measured using 18 different objects constructed from 10 cubes glued together. Participants were asked to draw these objects from blind haptic perception, and drawings were scored by two independent judges. The maximum score was 24 for each of MRT A and MRT C, 60 for SDT, and 18 for the drawings. The drawing score based on haptic perception [median = 17 (lower quartile = 16, upper quartile = 18)] correlated with MRT A [14 (9, 17)], MRT C [9 (7, 12)] and SDT [44 (36, 52)] scores with a Spearman's rank correlation coefficient of 0.395 (p = 0.0049), 0.507 (p = 0.0002) and 0.606 (p < 0.0001), respectively. Spatial abilities assessed by vision-based tests were correlated with a drawing score based on haptic perception of objects. Future research should investigate the contribution of haptic-based and vision-based spatial abilities on learning 3D anatomy from physical models.

Using artificial intelligence to grade practical laboratory examinations: Sacrificing students' learning experiences for saving time?

The use of artificial intelligence (AI) by students has recently been made a key topic among educators because of the potential to transform students' learning experiences. However, the use of AI-based software by instructors has not received the same level of consideration despite its recent accessibility and prevalence. This contribution discusses the benefits, challenges, and limitations of commercial AI-based software (Gradescope® ) for grading summative, short answer practical examinations in an undergraduate gross anatomy course. While the integration of Gradescope® in grading practical examinations reduces time and perceived instructor biases, it might erode personal relationships between students and instructors, especially with regard to individual feedback. Future research should assess best practices for incorporating AI technology into course grading considering the challenges and trade-offs to students and instructors.

Anatomical knowledge retention in Obstetrics and Gynaecology residents and impact of an e-learning tool.

PURPOSE: Anatomical knowledge of medical students and residents is insufficient and further anatomical sciences throughout medical curriculum may be necessary. The first aim of this study was to assess pelvic and perineal anatomical knowledge retention of Obstetrics and Gynaecology (Ob/Gyn) residents. The second was to assess the impact of an e-learning tool on anatomical knowledge. METHODS: A survey was sent by mail to medical students and Ob/Gyn residents. After completion, Ob/Gyn residents were randomised to "e-learning" group or to "Control" group. "E-learning" group had an unlimited access to a tool about female pelvic and perineum anatomy, implemented by iMAIOS society in their online platform. A second assessment of residents' anatomical knowledge was done 2 months after randomisation. RESULTS: Ob/Gyn residents (N = 23) had a significant lower global score than third-year medical students (N = 103) (22.1% (± 10.2) vs 43.8% (± 12.1), p < 0.0001). Two months after randomisation, residents of "control" group demonstrated no significant difference between the two questionnaires (3.6%, p = 0.31), whilst the "e-learning" group demonstrated a significant increase overall (10.6%, p = 0.09). There was no significant difference on the post-intervention questionnaire between control and "e-learning" group (25.4% vs 33% respectively, p = 0.34). CONCLUSION: Knowledge of pelvic and perineal anatomy is poor. This e-learning tool aimed at improving anatomical knowledge retention but is not sufficient. A combination of traditional approaches and innovative solutions should be proposed throughout medical school and residency to maintain anatomical knowledge.

Evaluating a Photogrammetry-Based Video for Undergraduate Anatomy Education.

Modern anatomy education has benefitted from the development of a wide range of digital 3D resources in the past decades, but the impact of the COVID-19 pandemic has sparked an additional demand for high-quality online learning resources. Photogrammetry provides a low-cost technique for departments to create their own photo-realistic 3D models of cadaveric specimens. However, to ensure accessibility, the design of the resulting learning resources should be carefully considered. We aimed to address this by creating a video based on a photogrammetry model of a cadaveric human lung. Students evaluated three different versions of this video in a Likert-type online survey. Most responding students found this type of video useful for their learning and helpful for the identification of anatomical structures in real cadaveric specimens. Respondents also showed a preference for specific design features such as a short video length, white text on black background, and the presence of captions. The positive student feedback is promising for the future development of photogrammetry-based videos for anatomy education and this study has provided pilot data to improve the accessibility of such videos.

Automated grading of anatomical objective structured practical examinations using decision trees: An artificial intelligence approach.

An Objective Structured Practical Examination (OSPE) is an effective and robust, but resource-intensive, means of evaluating anatomical knowledge. Since most OSPEs employ short answer or fill-in-the-blank style questions, the format requires many people familiar with the content to mark the examinations. However, the increasing prevalence of online delivery for anatomy and physiology courses could result in students losing the OSPE practice that they would receive in face-to-face learning sessions. The purpose of this study was to test the accuracy of Decision Trees (DTs) in marking OSPE questions as a first step to creating an intelligent, online OSPE tutoring system. The study used the results of the winter 2020 semester final OSPE from McMaster University's anatomy and physiology course in the Faculty of Health Sciences (HTHSCI 2FF3/2LL3/1D06) as the data set. Ninety percent of the data set was used in a 10-fold validation algorithm to train a DT for each of the 54 questions. Each DT was comprised of unique words that appeared in correct, student-written answers. The remaining 10% of the data set was marked by the generated DTs. When the answers marked by the DT were compared to the answers marked by staff and faculty, the DT achieved an average accuracy of 94.49% across all 54 questions. This suggests that machine learning algorithms such as DTs are a highly effective option for OSPE grading and are suitable for the development of an intelligent, online OSPE tutoring system.

Ultrasound versus videos: A comparative study on the effectiveness of musculoskeletal anatomy education and student cognition.

Ultrasound imaging is a dynamic imaging technique that uses high-frequency sound waves to capture live images of the structures beneath the skin. In addition to its growing use in diagnosis and interventions, ultrasound imaging has the potential to reinforce concepts in the undergraduate medical curriculum. However, research assessing the impact of ultrasound on anatomy learning and student cognition is scarce. The purpose of this study was to compare the impact of ultrasound-based instruction versus narrated videos on students' understanding of anatomical relationships, as well as the role of intrinsic motivation, self-efficacy beliefs, and students' attitudes in this process. A booster course on anterior leg and wrist anatomy was offered to second-year medical students. A randomized controlled trial with a cross-over design allocated students to either an ultrasound-based teaching condition (cohort A) or a narrated anatomy video condition (cohort B). Next, participants were crossed to the alternative intervention. At the start of the study (T0), baseline anatomy knowledge, intrinsic motivation, self-efficacy beliefs, and spatial ability were measured. After the first intervention (T1) and at the end of the study (T2), both cohorts were administered an anatomy test, an intrinsic motivation scale, and a self-efficacy scale. In addition, each student was asked to fill out a perception survey after the ultrasound intervention. Finally, building on the cross-over design, the most optimal sequence of interventions was examined. A total of 181 students participated (cohort A: n = 82, cohort B: n = 99). Both cohorts performed comparably on the baseline anatomy knowledge test, spatial ability test, intrinsic motivation, and self-efficacy scale. At T1, cohort B outperformed cohort A on the anatomy test (p = 0.019), although only a small effect size could be detected (Cohen's d = 0.34). Intrinsic motivation and self-efficacy of both cohorts were similar at T1. At T2, the anatomy test, intrinsic motivation, and self-efficacy scale did not reflect an effect after studying either sequence of the interventions. Students reported favorably about the ultrasound experience, but also mentioned a steep learning curve. Medical students found the hands-on ultrasound sessions to be valuable, increasing their interest in musculoskeletal anatomy and ultrasound imaging. However, the addition of ultrasound did not result in superior spatial anatomy understanding compared to watching anatomy videos. In addition, ultrasound teaching did not have a major effect on student cognition. Ultrasound-based teaching of musculoskeletal anatomy is regarded as difficult to learn, and therefore it is hypothesized that too high levels of cognitive load might explain the presented results.

Exploring factors influencing dental students' negative emotions during a gross anatomy laboratory in Taiwan.

Background/purpose: Negative emotions of medical students during a gross anatomy laboratory are documented in the field of medical education, but those of dental students are relatively less reported in the literature. The purpose of the present study was to explore negative emotions of dental students during the gross anatomy laboratory and possible influential factors. Materials and methods: Basic demographic variables, gross anatomy learning attitudes, and/or life attitudes were collected at five time points among year 2 dental students (n = 49) at a medical university in northern Taiwan. Multi-hierarchical regression analyses were executed to explore possible factors that led to negative emotions. Results: Students who were older, had more-positive attitudes towards life, and had more-positive attitudes towards the anatomy laboratory tended to have weaker negative emotions when they first faced the cadavers. Having a tendency to care about and help people and having a grateful attitude also significantly predicted weaker negative emotions at the middle and end of the semester, respectively. Conclusion: Negative emotions of younger dental students who first encounter a cadaver should be of concern. Striving to improve students' positive attitudes toward life, positive attitudes toward the gross anatomy laboratory, willingness to care about and help people, and an overall grateful attitude may help reduce negative emotions during the gross anatomy laboratory. At an institutional level, integrating educational activities that reduce negative emotions toward cadavers by dental students is highly recommended.
