The role of medical museums in contemporary medical education

From the early 19th century until the most recent two decades, open‐space and satellite museums featuring anatomy and pathology collections (collectively referred to as “medical museums”) had leading roles in medical education. However, many factors have caused these roles to diminish dramatically in recent years. Chief among these are the great advances in information technology and web‐based learning that are currently at play in every level of medical training. Some medical schools have abandoned their museums while others have gradually given away their museums' contents to devote former museum space to new classrooms, lecture halls, and laboratories. These trends have accelerated as medical school enrollment has increased and as increasing interest in biological and biomedical research activities have caused medical schools to convert museum space into research facilities. A few medical schools, however, have considered the contents of their museums as irreplaceable resources for modern medicine and medical education and the space these occupy as great environments for independent and self‐directed learning. Consequently, some medical schools have updated their medical museums and equipped them with new technologies. The Anatomical Museum of Leiden University Medical Center in The Netherlands and the Medical Museum of Kawasaki Medical School in Kurashiki, Okayama, Japan, are two examples of such upgraded museums. Student surveys at Leiden University have indicated that all students (100%) found audio‐guided museum tours to be useful for learning and majorities of them found guided tours to be clinically relevant (87%). However, 69% of students felt that museum visits should be optional rather than compulsory within the medical training curriculum.

Meta‐evaluation in clinical anatomy: A practical application of item response theory in multiple choice examinations

The nature of anatomy education has changed substantially in recent decades, though the traditional multiple‐choice written examination remains the cornerstone of assessing students' knowledge. This study sought to measure the quality of a clinical anatomy multiple‐choice final examination using item response theory (IRT) models. One hundred seventy‐six students took a multiple‐choice clinical anatomy examination. One‐ and two‐parameter IRT models (difficulty and discrimination parameters) were used to assess item quality. The two‐parameter IRT model demonstrated a wide range in item difficulty, with a median of ?1.0 and range from ?2.0 to 0.0 (25th to 75th percentile). Similar results were seen for discrimination (median 0.6; range 0.4–0.8). The test information curve achieved maximum discrimination for an ability level one standard deviation below the average. There were 15 items with standardized loading less than 0.3, which was due to several factors: two items had two correct responses, one was not well constructed, two were too easy, and the others revealed a lack of detailed knowledge by students. The test used in this study was more effective in discriminating students of lower ability than those of higher ability. Overall, the quality of the examination in clinical anatomy was confirmed by the IRT models. Anat Sci Educ 3:17–24, 2010. © 2009 American Association of Anatomists.     

Student‐centered integrated anatomy resource sessions at Alfaisal University

Alfaisal University is a new medical school in Riyadh, Kingdom of Saudi Arabia that matriculates eligible students directly from high school and requires them to participate in a hybrid problem‐based learning (PBL) curriculum. PBL is a well‐established student‐centered approach, and the authors have sought to examine if a student‐centered, integrated approach to learn human structures leads to positive perceptions of learning outcomes. Ten students were divided into four groups to rotate through wet and dry laboratory stations (integrated resource sessions, IRSs) that engaged them in imaging techniques, embryology, histology, gross anatomy (dissections and prosections), surface anatomy, and self‐directed learning questions. All IRSs were primarily directed by students. During two second‐semester organ system blocks, forty students responded to a structured questionnaire designed to poll students' perceptions of changes in their knowledge, skills, and attitudes as a result of IRS. The majority (60%) of students felt that the student‐centered approach to learning enhanced their medical knowledge. Most students also felt that the IRS approach was advantageous for formulating clear learning objectives (55%) and in preparing for examinations (65%). Despite their positive feelings toward IRS, students did not view this learning approach as an adequate replacement for the knowledge gained from lectures and textbooks. Students' performance on objective structured practical examinations improved significantly for the two curricular blocks that included IRS compared with earlier non‐IRS blocks. A student‐centered approach to teach human structure in a hybrid PBL curriculum may enhance understanding of the basic sciences in first‐year medical students.

Building virtual models by postprocessing radiology images: A guide for anatomy faculty

Radiology and radiologists are recognized as increasingly valuable resources for the teaching and learning of anatomy. State‐of‐the‐art radiology department workstations with industry‐standard software applications can provide exquisite demonstrations of anatomy, pathology, and more recently, physiology. Similar advances in personal computers and increasingly available software can allow anatomy departments and their students to build their own three‐dimensional virtual models. Appropriate selection of a data‐set, followed by processing and presentation are the key steps in creating virtual models. The construction, presentation, clinical application, and educational potential of postprocessed imaging techniques including multiplanar reformats, minimum intensity projections, segmentation, volume‐rendering, surface‐rendering, fly‐throughs, virtual endoscopy, angiography, and cine‐loops are reviewed using examples created with only a personal computer and freeware software. Although only static images are presented in this article, further material is available online within the electronic version of this article. Through the use of basic and advanced image reconstruction and also paying attention to optimized presentation and integration, anatomy courses can be strengthened with appropriate radiological material. There are several key advantages for the anatomy department, which is equipped with the ability to produce virtual models using radiology images: (1) Opportunities to present anatomy using state‐of‐the‐art technology as an adjunct to current practices, (2) a means to forge an improved relationship with the local radiology department, and (3) the ability to create material locally, which is integrated with the local curriculum avoiding the problem of information overload when using the internet or other commercially available resources.

The gross anatomy course: An analysis of its importance

The gross anatomy dissection course is a cost‐intensive piece of undergraduate medical education that students and professionals alike describe as very important within the overall medical curriculum. We sought to understand more explicitly students' valuation of gross anatomy as an “important” course and so developed a quantitative longitudinal questionnaire. Medical students (n = 124) enrolled in the winter term 2006/2007 gross anatomy course at the Ulm University Faculty of Medicine were surveyed anonymously prior to, in the middle of, and at the end of the dissection course. Subgroups of students expressing rising or falling opinions of course value were identified and correlated with student opinions about the course's ability to convey professional competencies. Five‐point Likert scales were used for each survey item, which included such standardized instruments as the NeoFFI, BSI, and FBM. The study confirmed that medical students believe dissection to be valuable. Students indicated that participation in the course facilitated acquisition of anatomy knowledge as well as skills related to teamwork, coping with stress, and, to a lesser extent, time management. Students also noted that they developed less empathy than expected beforehand. Significant subgroup differences were observed relative to the competencies of teamwork, stress coping strategies, and empathy, as well as in students' stress levels associated with having to take a dissection course. Our study builds on previous work that has shown dissection courses help students develop professional competencies. The increase in professionalism might be a reason for the generally high value students place on the gross anatomy dissection course, Anat Sci Educ 3:3–11, 2010. © 2010 American Association of Anatomists.     

A functional model of the digital extensor mechanism: Demonstrating biomechanics with hair bands

The action of muscles about joints can be explained through analysis of their spatial relationship. A functional model of these relationships can be valuable in learning and understanding the muscular action about a joint. A model can be particularly helpful when examining complex actions across multiple joints such as in the digital extensor mechanism of the hand. A functional model using two hair bands representing the components of the digital extensor mechanism is described. Through superimposition of the model over one's digit, the combined actions of metacarpophalangeal joint flexion and interphalangeal joint extension are clearly demonstrated. The model provides a conceptual demonstration to enhance understanding of this unique combination of muscle actions about multiple joints.

Design,implementation, and evaluation of an innovative anatomy course

Starting in 2004, a medical school gross anatomy course faced with a 30% cut in hours went through an extensive redesign, which transformed a traditional dissection course into a course with a clinical focus, learning societies, and extensive on‐line learning support. Built into the redesign process was an extensive and ongoing assessment process, which included student focus groups, faculty development, surveys, and examinations. These assessments were used formatively, to enhance the course from year to year, and summatively, to determine how well the course was meeting the new learning objectives. The assessments from focus groups and faculty development prompted changes in support structures provided to students and the training and preparation of faculty. Survey results showed that, after student satisfaction declined the first year, satisfaction increased steadily through the fourth iteration as the course gained acceptance by students and faculty alike. There was a corresponding increase in the performance of students on course examinations. An additional examination given to students one and a half and three years after their anatomy course ended demonstrated the redesigned course's long‐term effectiveness for retaining anatomical knowledge and applying it to clinical cases. Compared to students who took the original course, students who took the shorter, more clinical course performed as well, or better, on each section of the examination. We attribute these positive results to the innovative course design and to the changes made based on our formative assessment program.
