Do we need dissection in an integrated problem-based learning medical course? Perceptions of first- and second-year students

BACKGROUND: The introduction of a problem-based learning (PBL) curriculum at the School of Medicine of the University of Melbourne has necessitated a reduction in the number of lectures and limited the use of dissection in teaching anatomy. In the new curriculum, students learn the anatomy of different body systems using PBL tutorials, practical classes, pre-dissected specimens, computer-aided learning multimedia and a few dissection classes. The aims of this study are: (1) to assess the views of first- and second-year medical students on the importance of dissection in learning about the anatomy, (2) to assess if students' views have been affected by demographic variables such as gender, academic background and being a local or an international student, and (3) to assess which educational tools helped them most in learning the anatomy and whether dissection sessions have helped them in better understanding anatomy. METHODS: First- and second-year students enrolled in the medical course participated in this study. Students were asked to fill out a 5-point Likert scale questionnaire. Data was analysed using Mann-Whitney's U test, Wilcoxon's signed-ranks or the calculation of the Chi-square value. RESULTS: The response rates were 89% for both first- and second-year students. Compared to second-year students, first-year students perceived dissection to be important for deep understanding of anatomy (P < 0.001), making learning interesting (P < 0.001) and introducing them to emergency procedures (P < 0.001). Further, they preferred dissection over any other approach (P < 0.001). First-year students ranked dissection (44%), textbooks (23%), computer-aided learning (CAL), multimedia (10%), self-directed learning (6%) and lectures (5%) as the most valuable resources for learning anatomy, whereas second-year students found textbooks (38%), dissection (18%), pre-dissected specimens (11%), self-directed learning (9%), lectures (7%) and CAL programs (7%) as most useful. Neither of the groups showed a significant preference for pre-dissected specimens, CAL multimedia or lectures over dissection. CONCLUSIONS: Both first- and second-year students, regardless of their gender, academic background, or citizenship felt that the time devoted to dissection classes were not adequate. Students agreed that dissection deepened their understanding of anatomical structures, provided them with a three-dimensional perspective of structures and helped them recall what they learnt. Although their perception about the importance of dissection changed as they progressed in the course, good anatomy textbooks were perceived as an excellent resource for learning anatomy. Interestingly, innovations used in teaching anatomy, such as interactive multimedia resources, have not replaced students' perceptions about the importance of dissection.     

The anatomy lesson of the SARS-CoV-2 pandemic: irreplaceable tradition (cadaver work) and new didactics of digital technology

AimTo compare the efficacy of different components of online and contact anatomy classes as perceived by medical students.MethodsAn anonymous course evaluation survey was conducted at the end of the academic year 2019/2020. The organization of classes due to the SARS-CoV-2 pandemic provided our students with a unique opportunity to compare online and contact classes. Students’ responses were analyzed according to the type of obtained data (ratio, ordinal, and categorical).ResultsThe response rate was 95.58%. Approximately 90% of students found anatomical dissection and practical work in general to be the most important aspect of teaching, which could not be replaced by online learning. During online classes, students missed the most the interaction with other students, followed by the interaction with student teaching assistants and teaching staff. Very few students found contact lectures useful, with most students reporting that they could be replaced with recorded video lectures. In contrast, recorded video lectures were perceived as extremely helpful for studying. Regular weekly quizzes were essential during online classes as they gave students adequate feedback and guided their learning process. Students greatly benefitted from additional course materials and interactive lessons, which were made easily available via e-learning platform.ConclusionsAnatomical dissection and interaction during contact classes remain the most important aspects of teaching anatomy. However, online teaching increases learning efficiency by allowing alternative learning strategies and by substituting certain components of contact classes, thus freeing up more time for practical work.

From the middle of the last century, lecturers in anatomy courses for medical students have faced two major challenges. The first has been how to incorporate the rapidly expanding new medical knowledge into the curricula. This required a reorganization of the existing curricula, and anatomy in particular was under pressure to reduce teaching hours and the student load (1-3). The second challenge has been how to modernize the teaching approach and didactically redesign the anatomy course. There has been pressure to replace cadaver work due to high expenses and high organizational demands. In many medical schools, authorities have advocated the idea that cadaver work can be replaced by other learning approaches with identical final outcomes (4). This pressure has become particularly notable in recent years and has been advocated by advancements in new digital technologies such as augmented and virtual reality (5).Anatomy is one of the fundamental and most demanding courses in any medical school curriculum. A frequent point of discussion is how to approach teaching anatomy and facilitate students’ comprehension of difficult concepts and memorization of vast amounts of new information. Universities worldwide adopt different teaching approaches. Modern teaching usually includes a combination of teaching methods within integrated and multimodal approaches to anatomy teaching (6,7). Six techniques for anatomy education have been proposed: in-person lectures, cadaveric dissection, inspection of prosected specimens, models, radiological and living anatomy teaching, and computer-assisted learning (8). Some universities have implemented curricular changes, especially since the time allotted to anatomy education in Europe, the United States of America, and Australia has considerably declined (9). The majority of schools have switched from a completely traditional cadaver-based curriculum toward more interactive custom-made approaches that better fit the learning strategies of new generations and that appreciate technologies such as augmented and virtual reality, social networks, and imaging for a better understanding (7,10,11). Cadaver dissection, considered a gold standard for teaching anatomy (12), still remains widely used. While occasionally contested, its importance in different aspects of anatomy education has been proven by schools that returned to cadaver dissection after having temporarily abandoned it (3,13). However, meta-analyses suggest that educators should appreciate and reevaluate each instructional method in order to meet all the students’ needs, since none has so far been proven superior to any other (14).At the University of Zagreb School of Medicine (UZSM), we teach a cadaver dissection-oriented teaching curriculum, with the use of additional teaching methods/tools, such as prosection and instructions/demonstrations on cadavers and artificial anatomical models. In recent years, we have enhanced the provided e-learning by vastly expanding the materials and activities available on our online platform for communication and teaching. We have also implemented a new, functionally oriented textbook (15,16). These changes aimed to enhance the awareness of the subject''s clinical relevance and to raise the students’ active involvement in the course.Our Department has been systematically assessing students'' satisfaction with the Anatomy course through anonymous surveys (student evaluation of teaching) after the course completion. The Anatomy course is taught during two semesters in the first year of medical school. In the first semester of the academic year 2019/2020, we finished the planned curricular activities as scheduled using our usual multimethod approach. In the second semester, the SARS-CoV-2 (COVID-19) pandemic forced us to switch to exclusively online teaching for an extended period of time (17,18). Online teaching was prolonged because of the heavy damage sustained by the UZSM buildings in an earthquake that hit Zagreb on March 22, 2020 (19), immediately after the introduction of the first lock-down. We organized only a very short practical revision on cadavers and models in June, at the end of the academic year.Such an organization of classes in the academic year 2019/2020 allowed our students to provide unique feedback about the perceived advantages and disadvantages of different components of contact and online classes. It also allowed them to evaluate the significance of these classes for meeting the anatomy course’s aims and give feedback on the overall teaching approach of the faculty. Thus, we conducted a survey with the aim of analyzing information on the efficacy of contact and online classes in covering the anatomy course material. We also analyzed how students’ success on continuous assessment during the academic year related to the way they responded to different survey questions and whether there were significant differences in those responses.     

Remote Pathology teaching under the COVID-19 pandemic: Medical students' perceptions

ContextThe COVID-19 pandemic has forced traditional teaching to be re-structured and delivered online.ObjectiveTo analyse medical students' perceptions about the benefits and difficulties of the remote teaching of Pathology during the COVID-19 pandemic.DesignA cross-sectional study was performed with an online survey applied to students from the third and fourth year of medical graduation, who attended the remote teaching of Pathology during the COVID-19 pandemic. Online teaching methods consisted of synchronous activities with live interactive lectures, case-based discussions and asynchronous activities with recorded lectures, tutorials and texts available on the online teaching platform. Students' perceptions about the remote teaching of Pathology were assessed through online survey.ResultsNinety students (47.4%) of 190 participants completed the questionnaire, 45 were male and 52 in the third year of medical graduation. Perceived conditions that facilitated Pathology learning included the use of the online teaching platform and time flexibility for study. Students regarded live interactive lectures as superior to traditional face-to-face lectures. Perceived conditions that hindered the implementation of the online teaching included difficulty separating study from home activities, lack of motivation and worsening of quality of life due to physical distancing from colleagues and the faculty. Overall, the remote teaching of Pathology was positively valued by 80% of the students.ConclusionOnline tools allowed the content of Pathology to be successfully delivered to the students during the COVID-19 pandemic. This experience may be a model for future teaching activities of Pathology in health science education.     

Anatomy in medical education: Perceptions of undergraduate medical students

AimThe best method to teach anatomy is widely debated. A shift away from cadaveric dissection in UK medical schools towards newer approaches has taken place without adequate evaluation of their suitability. The impact of this on future anatomical and surgical competencies is unclear. We assessed student perceptions to different methods of anatomy teaching.MethodsAll 2nd year students at Leeds School of Medicine were invited to complete a matrix-grid questionnaire. Participants were asked to score six methods of anatomy teaching (dissection; prosection; lectures; models; PC software packages; living & radiological anatomy) using a 5-point Likert-type scale on the ability to achieve nine learning objectives. Kruskal–Wallis and Mann–Whitney analyses suitable for non-parametric data were used to evaluate differences in scores between teaching methods.Results170 students (71%) responded to the survey. Overall, dissection was the single highest scored method, followed by prosection. Newer approaches such as models, computer software packages and living & radiological anatomy scored comparatively worse. The most suitable method for achieving individual learning objectives was variable with dissection perceived as most suitable for four out of nine objectives.ConclusionsCadaveric dissection is a favourable approach for achieving important learning objectives in the field of anatomy. Further evaluation of teaching methods is required prior to changes being made in the curricula of UK medical schools.     

Flipped classroom – A student perspective of an innovative teaching method during the times of pandemic

BackgroundFlipped Classroom is a blended form of learning in which the traditional didactic lectures are replaced by active classroom learning experience. Flipping the lectures outside the classroom and using the classroom for active interaction and projects has been the need of the hour. It is an innovative way of learning anatomy.MethodsThe study was done at Department of Anatomy, ESIC Medical College, KK Nagar, Chennai. After obtaining ethical committee approval and Consent for participating in the study, Pre-test questionnaire was shared through Google forms. The lecture PowerPoint about anatomy of larynx was shared with the students. Next day, during the scheduled class, the students were asked to present anatomy of larynx using different types of models. Post-test questionnaires were also shared, and the students were asked to submit feedback forms at the end of the session. The students were assessed by a group of subject experts who assessed the student’s anatomical knowledge, innovation with which they prepared the model, presentation, correctness of presentation and clinical application.ResultsOut of the 126 first year MBBS undergraduates, 100 students actively participated in the study. 41% of students agreed and 47% of students strongly agreed that flipped classroom was an enjoyable way of learning. 51% of students strongly agreed that they were able to go through the lecture prior to the presentation.ConclusionsFlipped classroom enhanced student learning through knowledge applications. Flipped classroom helped teachers to review and understand how much their students have read, retained, and applied the knowledge which was catered to them. There was largely a positive response for flipped classroom though flipped classroom cannot replace a regular classroom. Flipped classroom can be cumbersome as it involves extensive planning and coordination. It can be used to promote interest in the subject. Flipped classroom enhanced peer assisted learning.     

Opiniones de profesores y alumnos sobre un programa integral online en medicina durante el confinamiento por COVID-19

IntroductionThe COVID-19 crisis led to the closure of the country's universities in March 2020, with total interruption of face-to-face activity. To dealt with last 2019/20 semester in lockdown, our Faculty of Medicine implemented a joint training program totally online with a «self-regulatory» teaching approach. This study presents the opinions of teachers and students.MethodsThe educational characteristics of the online Program for COVID-19 (POLAC), for 1st and 2nd year of medicine, structuring and organization of the intervention and academic results, have been described in other work. This study through online surveys explores the opinions of teachers and students. Two researchers coded the open-ended responses obtained thematically and independently, classifying them into categories.ResultsThe 8 teachers involved and a variable number of student by subject responded, receiving 234 questionnaires (17%). The students highlight as positive the optimization of the teaching resources used, the usefulness of the online tools, especially self-assessments and the doubts management system. The development of practical sessions and lack of face-to-face learning are highlighted as negative aspects of the Program. Dedication of teachers received positive and negative remarks. Teachers highlight the empowerment of the student's autonomy and the usefulness of online tools but also the additional need to be presence.ConclusionGlobally, the positive and negative comments are in line with the strengths and weaknesses of both online teaching and «self-regulatory» teaching approaches. More robust design studies are needed to verify the true scope of these results.     

Applying problem-based learning to the teaching of anatomy: the example of Harvard Medical School

The introduction of problem-based learning techniques into the teaching of anatomy has been subject to great controversies. This paper debates the rationale behind this concept using the example of the curriculum of Harvard Medical School in which problem-based learning techniques have been used during the past 20 years. The anatomy curriculum is covered during the eight first weeks of the medical studies, and is an original combination of discussions of clinical cases in small groups, and work in gross anatomy, histology and radiology laboratories. The lectures are reduced to the minimum and emphasize general concepts. In this setting, the learning of anatomy is mostly led by students who have prepared for the different laboratory sessions and tutorials. The implementation of problem-based learning to the teaching of anatomy requires a close follow-up of each student with regular feedbacks on his work. Tutorials must be considered as a cornerstone between lectures and work in laboratories. Traditional aspects of the teaching of anatomy, such as work in dissection laboratories, are given an important role as they are aimed to clear-up misunderstood points. Further studies are required to compare at the long term the level of medical students who learned anatomy in a problem based versus traditional learning setting.     

Teaching histology and anatomy online during the COVID-19 pandemic

The aim of this study is to analyze differences in participation, and in the results obtained in the anatomy and histology exams, over two academic years of the Sport Sciences degree course. During the first semester of the academic year 2019/2020 both the lectures and the exam took place face-to-face, while during the academic year 2020/2021 everything was done online. Statistical analysis revealed that the online modality was especially advantageous for the anatomy exam. Students' opinions were also assessed through a short questionnaire. The results showed that teachers involved themselves in both groups. Students needed to interact socially with teachers and colleagues and to ask them questions. Even if the differences were not significant, the difference was greater for face-to-face students in most comparisons. Finally, the most common methods of peer communication were by social media.     

The impact of the learning environment sudden shifts on students’ performance in the context of the COVID-19 pandemic

IntroductionThis study aims to determine the effect of sudden changes in learning environments on students’ performance, in the context of the COVID-19 pandemic lockdown. We present an analysis of the kinesiology program, focusing on the learning modality changes through the years, and its impact on students’ performance.MethodsWe analyzed three periods over five years. During the Pre-pandemic period (2018-2019), classes had been taught in-person, during the pandemic (2020-2021) classes had been taught online, and during end of lockdown (2022) classes had return to in-person modality. In addition, we also examined the academic performance outcomes by gender during the three periods.ResultsWe found that the academic performance significantly increased in all cohort of career, increasing the average grade from 4.7 ± 0.08 (2018 to 2019, in-person) to 5.15 ± 0.07 during the pandemic period, from 2020 to 2021, when online modality was utilized. Furthermore, when returning to in-person classes in 2022, the academic performance reduced significantly to 4.6 ± 0.17. We also found that gender did not have an influence on academic performance in any of the learning environments presented. However, during clinical internships, we found that gender had a significantly effect on academic performance.ConclusionBased on these results, we conclude that the sudden shift from in-person learning to online learning modality helped improved the learning performance of student, reflecting those results on better students’ performance scores that could be associated with the enhanced efficient use of time.     

Off-line virtual microscopy in teaching histology to the undergraduate medical students: do the benefits correlate with the learning style preferences?

Introduction

Advances in technology have metamorphosed the methods and tools used in medical education. Teaching microscopic anatomy has shifted in the last few decades from conventional microscopy using light microscope and glass slides to virtual microscopy using computers and virtual slides.Students differ in their learning style preferences. Their performance is optimized when the teaching method or a strategy is adopted to their learning style preference.The purpose of this study was to determine the impact of using the off-line virtual slides in teaching histology on the performance of the first-year medical students and to ascertain its suitability to students with different learning style preferences.

A randomised controlled trial of a blended learning education intervention for teaching evidence-based medicine

Background

Few studies have been performed to inform how best to teach evidence-based medicine (EBM) to medical trainees. Current evidence can only conclude that any form of teaching increases EBM competency, but cannot distinguish which form of teaching is most effective at increasing student competency in EBM. This study compared the effectiveness of a blended learning (BL) versus didactic learning (DL) approach of teaching EBM to medical students with respect to competency, self-efficacy, attitudes and behaviour toward EBM.

Methods

A mixed methods study consisting of a randomised controlled trial (RCT) and qualitative case study was performed with medical students undertaking their first clinical year of training in EBM. Students were randomly assigned to receive EBM teaching via either a BL approach or the incumbent DL approach. Competency in EBM was assessed using the Berlin questionnaire and the ‘Assessing Competency in EBM’ (ACE) tool. Students’ self-efficacy, attitudes and behaviour was also assessed. A series of focus groups was also performed to contextualise the quantitative results.

Results

A total of 147 students completed the RCT, and a further 29 students participated in six focus group discussions. Students who received the BL approach to teaching EBM had significantly higher scores in 5 out of 6 behaviour domains, 3 out of 4 attitude domains and 10 out of 14 self-efficacy domains. Competency in EBM did not differ significantly between students receiving the BL approach versus those receiving the DL approach [Mean Difference (MD)=?0.68, (95% CI–1.71, 0.34), p=0.19]. No significant difference was observed between sites (p=0.89) or by student type (p=0.58). Focus group discussions suggested a strong student preference for teaching using a BL approach, which integrates lectures, online learning and small group activities.

Conclusions

BL is no more effective than DL at increasing medical students’ knowledge and skills in EBM, but was significantly more effective at increasing student attitudes toward EBM and self-reported use of EBM in clinical practice. Given the various learning styles preferred by students, a multifaceted approach (incorporating BL) may be best suited when teaching EBM to medical students. Further research on the cost-effectiveness of EBM teaching modalities is required.

     

Use of Web-based materials to enhance anatomy instruction in the health sciences

Teaching anatomy by dissection is under considerable pressure to evolve and/or even be eliminated, and curricular hours in the dissection laboratory are decreasing. As a possible means of easing this pressure, an online interactive anatomy program has been created to enhance the dissection experience, observational learning, and three-dimensional comprehension of human anatomy. An assessment was made of the utility of the program in preparing students for dissection laboratories and for examinations. The efficacy of the application was evaluated by first-year students and faculty with pre- and post-use surveys in anatomy courses at three medical schools. It was found that students felt better prepared if they utilized the Web site prior to their dissection laboratory, and faculty reported spending less time explaining basic concepts or techniques. It is concluded that a comprehensive online program significantly enhances the quality and efficiency of instruction in human anatomy in the dissection laboratory and could prove to be a useful tool at other institutions.     

A Cost-Effectiveness Analysis of Blended Versus Face-to-Face Delivery of Evidence-Based Medicine to Medical Students

BackgroundBlended learning describes a combination of teaching methods, often utilizing digital technologies. Research suggests that learner outcomes can be improved through some blended learning formats. However, the cost-effectiveness of delivering blended learning is unclear.ObjectiveThis study aimed to determine the cost-effectiveness of a face-to-face learning and blended learning approach for evidence-based medicine training within a medical program.MethodsThe economic evaluation was conducted as part of a randomized controlled trial (RCT) comparing the evidence-based medicine (EBM) competency of medical students who participated in two different modes of education delivery. In the traditional face-to-face method, students received ten 2-hour classes. In the blended learning approach, students received the same total face-to-face hours but with different activities and additional online and mobile learning. Online activities utilized YouTube and a library guide indexing electronic databases, guides, and books. Mobile learning involved self-directed interactions with patients in their regular clinical placements. The attribution and differentiation of costs between the interventions within the RCT was measured in conjunction with measured outcomes of effectiveness. An incremental cost-effectiveness ratio was calculated comparing the ongoing operation costs of each method with the level of EBM proficiency achieved. Present value analysis was used to calculate the break-even point considering the transition cost and the difference in ongoing operation cost.ResultsThe incremental cost-effectiveness ratio indicated that it costs 24% less to educate a student to the same level of EBM competency via the blended learning approach used in the study, when excluding transition costs. The sunk cost of approximately AUD $40,000 to transition to the blended model exceeds any savings from using the approach within the first year of its implementation; however, a break-even point is achieved within its third iteration and relative savings in the subsequent years. The sensitivity analysis indicates that approaches with higher transition costs, or staffing requirements over that of a traditional method, are likely to result in negative value propositions.ConclusionsUnder the study conditions, a blended learning approach was more cost-effective to operate and resulted in improved value for the institution after the third year iteration, when compared to the traditional face-to-face model. The wider applicability of the findings are dependent on the type of blended learning utilized, staffing expertise, and educational context.     

Anatomy teaching: students’ perceptions

The goal of this study was to analyse students’ perceptions of anatomy teaching. A questionnaire was distributed to two classes of first year dental students taught anatomy in both problem-based learning (PBL) and traditional formats. The questionnaire explored the students’ most preferred techniques for learning anatomy, their examination preferences and their perceived level of mastery of anatomy. Fifty-seven (95%) students completed the survey. The most commonly used study aids were atlases, dissection and lecture notes (in descending order). Students expressed the desire for the final examination to include both written and oral components. Six months after the final examination, the students reported their perceived level of mastery of anatomy as either “very good” or “OK”. Even in the PBL curriculum 39% of both classes felt it is necessary to have quizzes during the course to motivate and guide them in studying anatomy.     

Student learning preferences and the impact of a multimedia learning tool in the dissection course at the University of Munich

How do students use multimedia tools to support their learning during a gross anatomy dissection course? We investigated this question in the anatomic dissection course for first year medical students at the University of Munich (n=850) by giving all participating students access to an anatomical multimedia CD-ROM. The use of this multimedia learning tool was voluntary and it was not essential for the end-of-course examination.After the examination, two questionnaires (return rate first questionnaire n₁=347, 41%; return rate second questionnaire n₂=644, 76%) were given to the surveyed students with the following content: evaluation of the multimedia learning tool, details about the usage of different kinds of available learning media, and finally an evaluation of the media used for teaching during the course. Furthermore we collected personal data from participants such as age, gender and the score achieved in the examination.Classical textbooks and anatomical atlases were used by 84% of students for preparation. The multimedia learning tool was used by 34% as an additional media for learning. The multimedia learning tool was not used alone. The data showed differences with regard to gender and performance of students, but not relating to age. Students rated the computer-specific features, e.g. three-dimensional (3D) models, virtual simulations, and an interactive quiz module, as major reasons for using the multimedia learning tool.Our results show that medical students use anatomic multimedia learning tools primarily as an additional medium for learning, and thus lead to the conclusion that the main learning media are still textbooks and anatomic atlases.     

Clima de aprendizaje y preparación para el aprendizaje autodirigido en cirugía: ¿influye el enfoque de enseñanza?

IntroductionThe effect of learning climate effect on self-directed student learning remains controversial. This study aims to compare this effect between 2 teaching approaches in surgery.MethodsUsing previously validated questionnaires, student perceptions about climate and self-directed learning were evaluated in an interactive teaching approach (inverted classroom) and a traditional approach (lecture). The inter-variable correlations in each group were calculated and then between both groups.ResultsA total of 75 students (inverted classroom) and 74 students (lecture) self-completed questionnaires at the end of surgery course. Although the learning climate was higher in the inverted classroom, the perceptions of self-directed learning were similar in both groups. All correlations, between the scores of the 2 questionnaires, overall, and by domain, were higher in the inverted classroom, compared with lectures (P< .05)ConclusionsThe inverted classroom fosters a higher learning climate, with respect to the lecture, which is positively related to self-directed learning in surgical undergraduates. However, self-directed learning skills were similar in both approaches, and offer opportunities to evaluate other factors in this context.     

The Relationships among Media Usage Regarding COVID-19, Knowledge about Infection,and Anxiety: Structural Model Analysis

BackgroundWe examined the effects of mass media usage on people''s level of knowledge about coronavirus disease 2019 (COVID-19), fear of infection, prejudice towards infected people, and anxiety level. In addition, we investigated whether knowledge about COVID-19 can reduce fear, prejudice, and anxiety.MethodsWe performed an anonymous online survey in 1,500 residents aged 19–65 years between April 24 and May 5 of 2020. Anxiety level was assessed using the generalized anxiety disorder-7 scale. We used a questionnaire to investigate COVID-19-related media use, knowledge about COVID-19, fear of infection, and prejudice towards infected people. We analyzed the relationships among the variables using the structural equation model.ResultsMedia use had significant effects on fear of infection, prejudice against infected people, and anxiety. Knowledge about COVID-19 had a significant protective effect on fear of infection, prejudice against infected people, and anxiety. However, the effect of media use on knowledge about COVID-19 was not statistically significant. There was a partial mediating effect of prejudice against infected people and fear of infection on media usage and anxiety.ConclusionOur study demonstrated significant effects of mass media coverage regarding COVID-19 on fear, prejudice, and anxiety. While knowledge about COVID-19 could decrease fear, prejudice, and anxiety, the use of mass media did not enhance this knowledge. Medical societies should guide mass media reporting of COVID-19 and provide appropriate public education.     

Attitudes of professional anatomists to curricular change

Throughout the world, recent developments in medical curricula have led to marked changes in the teaching of gross anatomy. This change has involved decreasing curricular student contact time and the use of new methods for anatomical teaching. Some "modern" anatomists have welcomed the arrival of these novel methods while other, more "traditional," anatomists have fought to maintain the use of cadaveric dissection. Consequently, controversy over teaching methods has developed to the point that "modernist" and "traditionalist" views within the community of professional anatomists seem to have diverged such that the importance of gross anatomy in the medical curriculum is disputed and that cadaveric dissection by students is no longer the preferred method of teaching. This study tests this hypothesis using Thurstone and Chave attitude analyses to assess attitudes to educational change and the importance of anatomy in medicine and a matrix questionnaire that required professional anatomists to relate course aims to different teaching methods. In total, 112 completed questionnaires were received from anatomists who are employed at higher education institutions that use various teaching methods and who span the academic hierarchy. The results suggest that over 90% of anatomists favor educational change and approximately 98% of professional anatomists believe that gross anatomy has an important role to play in clinical medicine. A clear majority of the anatomists (69%) favored the use of human cadaveric dissection over other teaching methods (this method seeming to achieve a range of different course aims/objectives) (P < 0.001; Kruskal-Wallis). Using Kruskal-Wallis statistical tests, the order-of-preference for teaching methods was found to be as follows: 1. Practical lessons using cadaveric dissection by students. 2. Practical lessons using prosection. 3. Tuition based upon living and radiological anatomy. 4. Electronic tuition using computer aided learning (CAL). 5. Didactic teaching alone (e.g. lectures/class room-based tuition). 6. Use of models. The preference for the use of human cadaveric dissection was evident in all groups of anatomists, whether "traditionalist" or "modernist" (P = 0.002, Chi-squared). These findings are therefore not consistent with our initial hypothesis.     

The use of small group case-based exercises in human gross anatomy: A method for introducing active learning in a traditional course format

As part of the curricular change at the University of Rochester School of Medicine and Dentistry, we focused on active learning and greater integration of basic and clinical sciences. With these objectives in mind, this report describes the use of small-group, case-based exercises in our gross anatomy course and provides one example of integrating such activities into a traditional course. In addition to formal lectures and laboratory dissection, students meet approximately every fourth class period in small groups to discuss a clinical case which focuses on the relevant anatomy taught at that time. Two first-year students lead each small group; one fourth-year student facilitator also attends to provide clinical correlations, answer questions, and reinforce the anatomy. Formative feedback suggests students enthusiastically endorse the self-directed active learning; they feel these exercises offer both a valuable approach to learning and an opportunity to practice presentation and leadership skills. First-year students enjoy the interaction with fourth-year facilitators and the fourth-year students appreciate the opportunity to review basic science material. Our data suggest that students learn to “think” about the anatomy, and we hope learn to use their understanding and knowledge base in a practical fashion. Moreover, these case-based exercises can fit nicely into a variety of curricular formats, especially where problem-based tutorials may not be feasible or desirable. © 1994 Wiley-Liss, Inc.     

Can “YouTube” help students in learning surface anatomy?

Aims

In a problem-based learning curriculum, most medical students research the Internet for information for their “learning issues.” Internet sites such as “YouTube” have become a useful resource for information. This study aimed at assessing YouTube videos covering surface anatomy.

Method

A search of YouTube was conducted from November 8 to 30, 2010 using research terms “surface anatomy,” “anatomy body painting,” “living anatomy,” “bone landmarks,” and “dermatomes” for surface anatomy–related videos. Only relevant video clips in the English language were identified and related URL recorded. For each videotape the following information were collected: title, authors, duration, number of viewers, posted comments, and total number of days on YouTube. The data were statistically analyzed and videos were grouped into educationally useful and non-useful videos on the basis of major and minor criteria covering technical, content, authority, and pedagogy parameters.

Results

A total of 235 YouTube videos were screened and 57 were found to have relevant information to surface anatomy. Analysis revealed that 15 (27%) of the videos provided useful information on surface anatomy. These videos scored (mean?±?SD, 14.0?±?0.7) and mainly covered surface anatomy of the shoulder, knee, muscles of the back, leg, and ankle, carotid artery, dermatomes, and anatomical positions. The other 42 (73%) videos were not useful educationally, scoring (mean?±?SD, 7.4?±?1.8). The total viewers of all videos were 1,058,634. Useful videos were viewed by 497,925 (47% of total viewers). The total viewership per day was 750 for useful videos and 652 for non-useful videos. No video clips covering surface anatomy of the head and neck, blood vessels and nerves of upper and lower limbs, chest and abdominal organs/structures were found.

Conclusions

Currently, YouTube is an inadequate source of information for learning surface anatomy. More work is needed from medical schools and educators to add useful videos on YouTube covering this area.
