In modern medical curricula, embryology is typically taught through lectures, with a few institutions providing tutorials. The use of 3-D videos or animations enables students to study these embryological structures and how they change with time. The aim of this study was to assess the quality of cardiac embryology videos available on YouTube. A systematic literature review regarding the use of YouTube in teaching or learning cardiac embryology identified no papers that examined this specific question, and next, a systematic search of YouTube was performed. A total of 1200 cardiac embryology videos were retrieved using 12 specific search terms, with 370 videos retrieved under two or more search terms and excluded. A further 511 videos were excluded under additional, specific criteria. The remaining 319 videos were evaluated with the YouTube Video Assessment Criteria (UTvAC), with 121 rated as “useful.” Videos on YouTube are uploaded with a wide audience in mind, from children to cardiologists, and content control is imperfect. Multiple videos were identified as duplicates of videos from original channels, typically without attribution. While 49 videos showed operations or human material, none contained an ethical statement regarding consent, and only 10 of these included an age restriction or graphical advisory. While there are useful videos for medical students studying cardiac embryology on YouTube, intuitive search strategies will also identify many with irrelevant content and of variable quality. Digital competence and search strategies are not innate skills, so educators should teach students to assess information so as to avoid overload or “filter failure.”  相似文献

This viewpoint commentary focuses on a proposal for integrated anatomy education in undergraduate college from Dr. Darda published in the Anatomical Sciences Education. Although the proposal is for college level education, the proposal echoes some ideas proposed a century ago by Abraham Flexner when he wrote his report titled “Medical Education in the United States and Canada.” It begins with an acknowledgement of the author's status as an outsider. There have been numerous calls for change in basic science education, particularly in medical education. Interestingly, however, the monumental reforms of the “Flexner Report” were impelled largely from outside the specific discipline of medical education. The commentary discussion then moves to observations about the proposal for Integrative Anatomy and support for the proposal from both the Flexner Report and the 2009 report from the Association of American Medical Colleges and the Howard Hughes Medical Institute, “Scientific Foundations for Future Physicians.” The essay considers the benefits of the research on the learning sciences that now inform our work in education; the influence of competency‐based education that frees education from a lock‐step approach of course completion to a student‐focused integrative approach to learning; and the availability of online resources for anatomy education through repositories, such as MedEdPORTAL. The final observation is that the changes underway in education and in the sciences basic to medicine, in particular, are substantial and will require the dialogue that Dr. Darda is promoting with his provocative proposal.

Anatomy students studying dissected anatomical specimens were subjected to either a loosely‐guided, self‐directed learning environment or a strictly‐guided, preformatted gross anatomy laboratory session. The current study's guiding questions were: (1) do strictly‐guided gross anatomy laboratory sessions lead to higher learning gains than loosely‐guided experiences? and (2) are there differences in the recall of anatomical knowledge between students who undergo the two types of laboratory sessions after weeks and months? The design was a randomized controlled trial. The participants were 360 second‐year medical students attending a gross anatomy laboratory course on the anatomy of the hand. Half of the students, the experimental group, were subjected without prior warning to station‐based laboratory sessions; the other half, the control group, to loosely‐guided laboratory sessions, which was the course's prevailing educational method at the time. The recall of anatomical knowledge was measured by written reproduction of 12 anatomical names at four points in time: immediately after the laboratory experience, then one week, five weeks, and eight months later. The strictly‐guided group scored higher than the loosely‐guided group at all time‐points. Repeated ANOVA showed no interaction between the results of the two types of laboratory sessions (P = 0.121) and a significant between‐subject effect (P ≤ 0.001). Therefore, levels of anatomical knowledge retrieved were significantly higher for the strictly‐guided group than for the loosely‐guided group at all times. It was concluded that gross anatomy laboratory sessions with strict instructions resulted in the recall of a larger amount of anatomical knowledge, even after eight months.

The anatomical sciences have always been regarded as an essential component of medical education. In Canada, the methodology and time dedicated to anatomy teaching are currently unknown. Two surveys were administered to course directors and discipline leaders to gain a comprehensive view of anatomical education in Canadian medical schools. Participants were queried about contact hours (classroom and laboratory), content delivery and assessment methods for gross anatomy, histology, and embryology. Twelve schools responded to both surveys, for an overall response rate of 64%. Overall, Canadian medical students spend 92.8 (± 45.4) hours (mean ± SD) studying gross anatomy, 25.2 (± 21.0) hours for histology, and 7.4 (± 4.3) hours for embryology. Gross anatomy contact hours statistically significantly exceeded those for histology and embryology. Results show that most content is delivered in the first year of medical school, as anatomy is a foundational building block for upper-year courses. Laboratory contact time for gross anatomy was 56.8 (± 30.7) hours, histology was 11.4 (± 16.2) hours, and embryology was 0.25 (± 0.6) hours. Additionally, 42% of programs predominantly used instructor/technician-made prosections, another 33% used a mix of dissection and prosections and 25% have their students complete cadaveric dissections. Teaching is either completely or partially integrated into all Canadian medical curricula. This integration trend in Canada parallels those of other medical schools around the world where programs have begun to decrease contact time in anatomy and increase integration of the anatomical sciences into other courses. Compared to published American data, Canadian schools offer less contact time. The reason for this gap is unknown. Further investigation is required to determine if the amount of anatomical science education within medical school affects students' performance in clerkship, residency and beyond.  相似文献

Team‐based learning (TBL) is an instructional strategy that combines independent out‐of‐class preparation for in‐class discussion in small groups. This approach has been successfully adopted by a number of medical educators. This strategy allowed us to eliminate anatomy lectures and incorporate small‐group active learning. Although our strategy is a modified use of classical TBL, in the text, we use the standard terminology of TBL for simplicity. We have modified classical TBL to fit our curricular needs and approach. Anatomy lectures were replaced with TBL activities that required pre‐class reading of assigned materials, an individual self‐assessment quiz, discussion of learning issues derived from the reading assignments, and then the group retaking the same quiz for discussion and deeper learning. Students' performances and their educational experiences in the TBL format were compared with the traditional lecture approach. We offer several in‐house unit exams and a final comprehensive subject exam provided by the National Board of Medical Examiners. The students performed better in all exams following the TBL approach compared to traditional lecture‐based teaching. Students acknowledged that TBL encouraged them to study regularly, allowed them to actively teach and learn from peers, and this served to improve their own exam performances. We found that a TBL approach in teaching anatomy allowed us to create an active learning environment that helped to improve students' performances. Based on our experience, other preclinical courses are now piloting TBL. Anat Sci Ed 1:3–9, 2008. © 2007 American Association of Anatomists.  相似文献

Publications on anatomy in medical education appear to be largely anecdotal. To explore this, we investigated the literature on anatomy in medical education, aiming first to evaluate the contribution of the literature on anatomy in medical education to best evidence medical education (BEME) and second to evaluate the development of this literature toward more best evidence between 1985 and 2009. Four databases were searched for publications on anatomy in medical education published between 1985 and 2009, resulting in 525 references. Hundred publications were characterized by five variables (journal category, paper subject, paper category, author perspective, and paper perspective). Statements from these publications were characterized by two variables (category and foundation). The publications contained 797 statements that involved the words anatomy, anatomical, or anatomist. Forty-five percent of the publications contained no explicit research question. Forty percent of the statements made were about teaching methods and 17% about teaching content, 8% referred to practical value, and 10% to side effects of anatomy education. Ten percent of the statements were positional, five percent traditional, four percent self-evident, and two percent referred to quality of care. Fifty-six percent of the statements had no foundation, 17% were founded on empirical data, and 27% by references. These results substantiated the critical comments about the anecdotal nature of the literature. However, it is encouraging to see that between 1985 and 2009 the number of publications is rising that these publications increasingly focus on teaching methods and that an academic writing style is developing. This suggests a growing body of empirical literature about anatomy education.  相似文献

This article illustrates details of the planning, building, and improvement phases of a cost‐efficient, full‐dissection gross anatomy laboratory on a campus of an historically design‐centric university. Special considerations were given throughout the project to the nature of hosting cadavers in a building shared amongst all undergraduate majors. The article addresses these needs along with discussion of relevant furnishings and infrastructure that went into the creation of a fully outfitted gross anatomy laboratory (ten cadavers) completed within a significantly constrained timeline and $210,000 budget.

Previous research has explored the experiences of medical students using body painting as a learning tool. However, to date, faculty experiences and views have not been explored. This international qualitative study utilized a grounded theory approach with data collection through interviews with academics and clinicians who utilized body painting as part of their anatomical teaching. Twenty‐six anatomists participated in the study from 14 centers worldwide. Three themes emerged from the data: (1) the efficacy of body painting, (2) the promotion of knowledge retention and recall, (3) considerations and practicalities regarding the use of body painting as a teaching tool. Subthemes show that body painting is used as an adjunct to the curriculum for teaching surface anatomy and peer examination. Benefits included diffusing the formal curricula, high student engagement and learning for future clinical practice. Body painting was advocated for promoting knowledge retention and recall, particularly learning through the process of cognitive load due to combining the use of color and kinesthetic learning with anatomical theory. Critical discussions surfaced on the topic of undressing in the classroom due to cultural and personal considerations possibly leading to unequal involvement and different learning experiences. Overall results support previous research showing that anatomists appreciate body painting as an effective, enjoyable, engaging and cost efficient adjunct to the multimodal anatomy curriculum. The role of cognitive load theory in learning anatomy through body painting emerged from the data as a possible theoretical framework supporting learning benefits from body painting and is suggested for further investigation.

With integrated curricula and multidisciplinary assessments becoming more prevalent in medical education, there is a continued need for educational research to explore the advantages, consequences, and challenges of integration practices. This retrospective analysis investigated the number of items needed to reliably assess anatomical knowledge in the context of gross anatomy and histology. A generalizability analysis was conducted on gross anatomy and histology written and practical examination items that were administered in a discipline‐based format at Indiana University School of Medicine and in an integrated fashion at the University of Alabama School of Medicine and Rush University Medical College. Examination items were analyzed using a partially nested design in which items were nested within occasions (i:o) and crossed with students (s). A reliability standard of 0.80 was used to determine the minimum number of items needed across examinations (occasions) to make reliable and informed decisions about students' competence in anatomical knowledge. Decision study plots are presented to demonstrate how the number of items per examination influences the reliability of each administered assessment. Using the example of a curriculum that assesses gross anatomy knowledge over five summative written and practical examinations, the results of the decision study estimated that 30 and 25 items would be needed on each written and practical examination to reach a reliability of 0.80, respectively. This study is particularly relevant to educators who may question whether the amount of anatomy content assessed in multidisciplinary evaluations is sufficient for making judgments about the anatomical aptitude of students.

The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

The purpose of this study was to evaluate the extracurricular cadaveric dissection program available to medical students at an institution with a modern (time‐compressed, student‐centered, and prosection‐based) approach to medical anatomy education. Quantitative (Likert‐style questions) and qualitative data (thematic analysis of open‐ended commentary) were collated from a survey of three medical student cohorts who had completed preclerkship. Perceived benefits of dissection included the hands‐on learning style and the development of anatomy expertise, while the main barrier that limited participation was the time‐intensive nature of dissection. Despite perceived benefits, students preferred that dissection remain optional. Analysis of assessments for the MD2016 cohort revealed that dissection participation was associated with enhanced performance on anatomy items in each systems‐based unit examination, with the largest benefits observed on discriminating items that assessed knowledge application. In conclusion, this study revealed that there are academic and perceived benefits of extracurricular participation in dissection. While millennial medical students recognized these benefits, these students also indicated strong preference for having flexibility and choice in their anatomy education, including the choice to participate in cadaveric dissection.

Described in this article is a novel device that facilitates study of the cross‐sectional anatomy of the human head. In designing our device, we aimed to protect sections of the head from the destructive action of handling during anatomy laboratory while also ensuring excellent visualization of the anatomic structures. We used an electric saw to create 15‐mm sections of three cadaver heads in the three traditional anatomic planes and inserted each section into a thin, perforated display box made of transparent acrylic material. The thin display boxes with head sections are kept in anatomical order in a larger transparent acrylic storage box containing formaldehyde solution, which preserves the specimens but also permits direct observation of the structures and their anatomic relationships to each other. This box‐within‐box design allows students to easily view sections of a head in its anatomical position as well as to examine internal structures by manipulating individual display boxes without altering the integrity of the preparations. This methodology for demonstrating cross‐section anatomy allows efficient use of cadaveric material and technician time while also giving learners the best possible handling and visualization of complex anatomic structures. Our approach to teaching cross‐sectional anatomy of the head can be applied to any part of human body, and the value of our device design will only increase as more complicated understandings of cross‐sectional anatomy are required by advances and proliferation of imaging technology.

Anatomy departments across Africa were surveyed regarding the type of curriculum and method of delivery of their medical courses. While the response rate was low, African anatomy departments appear to be in line with the rest of the world in that many have introduced problem based learning, have hours that are within the range of western medical schools and appear to be well resourced. Human body dissection is a constant and strong aspect of the majority of the courses surveyed. The staff to student ratio appears to be relatively high in Africa, but in many of the responding African institutions, there appears to be little difficulty in attracting suitable faculty (including those who are medically qualified) to teach anatomy. Retaining this faculty, in some cases, may be difficult because of a global demand for anatomy educators. Anat Sci Ed 1:111–118, 2008. © 2008 American Association of Anatomists.  相似文献

Graduating physicians in all subspecialties have an increased need for competency in radiology, particularly since the use of diagnostic imaging continues to grow. To integrate the teaching of radiology with anatomy during the first year of medical school at Howard University, a novel approach was developed to overcome the limitations of resources including funding, faculty, and curricular time. The resulting program relies on self‐study and peer‐to‐peer interactions to develop proficiency at manipulating free versions of medical image viewer software (using the DICOM standard), identifying normal anatomy in medical images, and applying critical thinking skills to understand common clinical conditions. An effective collaborative relationship between a radiologist and anatomist was necessary to develop and implement the program of anatomic–radiographic instruction which consists of five tiers: (1) initial exposure to anatomy through dissection which provides a foundation of knowledge; (2) study of annotated radiographs from atlases; (3) a radiology quiz open to group discussions; (4) small group study of clinical cases with diagnostic images; and (5) radiographic tests. Students took all quizzes and tests by working from image datasets preloaded on their personal computers, mimicking the approach by which radiologists analyze medical images. In addition to stimulating student support of a new teaching initiative, the strengths of Howard's program are that it can be introduced into an existing preclinical curriculum in almost any medical school with minimal disruption, it requires few additional resources to implement and run, and its design is consistent with the principles of modern education theory.

Web‐based computer‐aided instruction (CAI) has become increasingly important to medical curricula. This multi‐year study investigated the effectiveness of CAI and the factors affecting level of individual use. Three CAI were tested that differed in specificity of applicability to the curriculum and in the level of student interaction with the CAI. Student personality preferences and learning styles were measured using the Meyers Briggs Type Indicator (MBTI) and Kolb's Learning Style Inventory (LSI). Information on “computer literacy” and use of CAI was collected from student surveys. Server logs were used to quantify individual use of respective CAI. There was considerable variability in the level of utilization of each CAI by individual students. Individual use of each CAI differed and was associated with gender, MBTI preferences and learning style, but not with “computer literacy.” The majority of students found the CAI useful for learning and used the CAI by themselves. Students who accessed the CAI resources most frequently scored significantly higher on exams compared with students who never accessed the resources. Our results show that medical students do not uniformly use CAI developed for their curriculum and this variability is associated with various attributes of individual students. Our data also provide evidence of the importance of understanding student preferences and learning styles when implementing CAI into the curriculum.

A lecture is not necessarily a monologue, promoting only passive learning. If appropriate techniques are used, a lecture can stimulate active learning too. One such method is demonstration, which can engage learners' attention and increase the interaction between the lecturer and the learners. This article describes two simple and useful tools for demonstration during gross anatomy lectures. One is an apron for demonstrating midgut rotation and the other is a simple “human” model for demonstrating the relationship between the uterus and the peritoneum.

Fewer and fewer programs are training graduate students and postdoctoral fellows in the classical anatomical disciplines. Nonetheless, there remains a need at all levels of clinical and basic science education for skilled instructors of anatomy, histology, and embryology. Two sessions at the 2006 annual meeting of the American Association of Anatomists (AAA) explored whether a system of accreditation would benefit students, institutions, and training programs. Although the value of accreditation was controversial, three challenges for the various anatomical societies emerged from these discussions: (1) To identify the skills and knowledge that should be shared among all anatomists, and the more specific skills and knowledge needed for the diverse settings in which anatomists work. (2) To address the historical inattention of institutions to the training of educators. (3) To develop strategies to lobby institutions and national organizations to support the training and work of educators in the anatomical sciences. One approach to meeting these challenges would be to develop guidelines for training programs. These guidelines would help graduate students seek the training they need, provide institutions with a benchmark to assess or develop training programs, and provide the basis for focusing lobbying efforts targeted at institutions or existing accreditation bodies.

Peer‐assisted learning has gained momentum in a variety of disciplines, including medical education. In Gothenburg, Sweden, medical students who have finished their compulsory anatomy courses have the option of working as teaching assistants (TAs). Teaching assistants provide small group teaching sessions as a complement to lectures given by faculty. Previously, TAs were left to handle the role as junior teachers by themselves, but since 2011, a continuation course in anatomy has been developed with the aim of providing the TAs better anatomy knowledge and guidance for teaching. The course was designed to comprise 7.5 ECTS credits (equivalent to 5 weeks of full‐time studies), and today all TAs are required to take this course before undertaking their own teaching responsibilities. This study aims to compare course evaluations of TA teaching before and after the introduction of the anatomy continuation course, in order to understand how students perceived teaching performed by self‐learned versus trained TAs. The results of this study demonstrate that there was a trend towards better teaching performed by trained TAs. The variability in rankings decreased significantly after the introduction of the continuation course. This was mainly due to an improvement among the TAs with the lowest levels of performance. In addition to comparing student rankings, TAs were interviewed regarding their experiences and perceptions within the continuation course. The course was generally positively regarded. The TAs described a sense of cohesion and appreciation since the institute invested in a course dedicated specifically for them.
