The relationships between learning outcomes and methods of teaching anatomy as perceived by professional anatomists

Changes in the teaching of gross anatomy have often involved decreasing student contact time alongside the use of new methods for teaching. However, there remains controversy over teaching methods and about whether cadaveric dissection by students should remain the preferred method. Furthermore, decisions concerning changes to curricula are more likely to be taken by choosing a method of teaching rather than by proper evaluation of what are the desired learning outcomes for a course in anatomy. The purpose of this study was to ascertain the attitudes of anatomists in Europe towards the methods of teaching best fitting a series of learning outcomes for anatomy and secondarily to test the hypothesis that, from evaluation of learning outcomes, anatomy is best taught by cadaveric dissection by the students. About 113 completed questionnaires were received from anatomists who are employed at higher education institutions that use various teaching methods. Most anatomists (69%) favored the use of cadaveric dissection above other teaching methods when considering the whole series of learning comes, this method seeming to achieve a range of different course aims/objectives, P < 0.001; Kruskal-Wallis). Consequently, these findings are consistent with our initial hypothesis. However, when individual learning outcomes were considered, the relationship was not so clear cut and, for example, little difference was discernible between teaching methods when considering learning outcomes related to the acquisition of anatomical knowledge. The use of human cadaveric dissection gained more approval when the skills-base was considered rather than just the content(knowledge)-base of an anatomical course.     

The relationships between learning outcomes and methods of teaching anatomy as perceived by medical students

The best method to teach anatomy continues to be widely debated. Many UK medical schools have recently changed their course structure with the use of cadaveric dissection declining. A recent study by Patel and Moxham ([ 2008] Clin. Anat. 21:182-189) found that professional anatomists viewed dissection to be the most suitable method to fulfil anatomical learning outcomes. The opinion of 580 second year medical students across two UK medical schools was surveyed. A methodology similar to that employed by Patel and Moxham ([ 2008] Clin. Anat. 21:182-189) aimed to explore which teaching methods students considered best to fulfil a prescribed set of anatomical learning outcomes. A total of 302 responses were returned (52%). Difference in students' opinion with regard to the teaching methods was statistically significant (P < 0.0001). A statistically significant agreement was found between the opinions of students from Imperial and Nottingham, and between the anatomists and the students, regarding the effectiveness of all teaching methods at meeting learning outcomes. Dissection was overall most "fit for purpose" in meeting learning outcomes, but no single teaching modality met all aspects of the curriculum. Dissection should remain a leading teaching modality in modern medical school anatomy courses. In addition to its role in the teaching of anatomy, it enables learning in a social context and holds broader learning opportunities to help future doctors best fulfill Good Medical Practice guidelines (General Medical Council, 2006). This, however, should be in the context of a multi-modal approach to the teaching of anatomy.     

Anatomical instruction and training for professionalism from the 19th to the 21st centuries

For most of the 19th century, anatomists in the United States saw the affective, emotional aspects of human dissection as salient ingredients in professional formation. Professionalism (or "character") signified medical integrity and guaranteed correct professional conduct. As gross anatomy came under siege in the late-19th and early-20th centuries, crowded out of medical curricula by the new experimental sciences, medical educators rethought what it was that dissecting a human body stood to give medical students. As they embraced a new understanding of professionalism premised on an allegiance to science, anatomists celebrated the habits of mind and sensibility to scientific investigation that could be acquired at the dissecting table. One consequence was a deliberate distancing of gross anatomy from the "art of medicine," and with it a de facto suppression of attention to the affective components of human dissection. During this period in the opening decades of the 20th century, the norm of silence about the emotional dimensions of dissection was set in place. The confluence of various movements by the 1960s and 1970s both revived attention to the emotional experience of dissection and sparked a renewed discussion about the relationship between the affective components of learning anatomy and the professional formation of future healers. There is a need to balance the tension between the "affective" and "scientific" aspects of anatomy, and by extension the tension between the "art" and "science" of medical practice. One method is to use small-group "learning societies" as a means to cultivate and meld both dimensions of the professional ethic.     

Status of gross anatomy in the U.S. and Canada: Dilemma for the 21st century

As a component of a recent academic review, the Department of Anatomy and Neurosciences faculty at the University of Texas Medical Branch in Galveston, Texas, developed a questionnaire designed to compare the curricula, direction, and challenges of their department with the approximately 140 anatomy departments in the U. S. and Canada. The response was overwhelming in that over 80% of the schools returned a completed questionnaire. One of the areas of interest revealed by this survey was a growing concern over significant changes in both medical school curricula and the future of anatomy departments. Most departments still used traditional lectures to present course material and the majority of the scheduled contact hours were in the dissection laboratory; however, other teaching formats, such as case studies and small group discussions, accounted for significantly more of the teaching effort. Nearly 20% of the schools were making major modifications in their teaching methods. The general trend was to include more integrated, problem-based learning and computer-assisted teaching while reducing overall content, didactic lectures, and rote memorization. The role and need for traditionally trained gross anatomists in medical education appeared to be diminishing as curricular reform moved toward more student-directed, faculty-facilitated programs. Concurrently, the recruitment and career development of gross anatomy faculty appeared to be influenced more by funding status than by academic training or teaching experience, as most departmental chairman were willing to hire non-anatomists and “train” them to assume an often reduced teaching load in gross anatomy courses. In addition, fewer graduate students were being trained in classical gross anatomy, a trend that better suited the emerging student-directed medical school curricula. The reduction in classically trained anatomists also appeared to reflect the widespread practice whereby anatomy faculty were rewarded far more for research than for teaching. Although the continued inclusion of gross anatomy in medical education appeared to be assured, its traditional mode of presentation and academic prominence will likely change by the turn of the century. © 1994 Wiley-Liss, Inc.     

Dissection from the Spanish anatomist's perspective: aims, attitudes, and related aspects

We present the results of a study conducted on participants of the 21st Congress of the Spanish Society of Anatomy, in which anatomists were asked their opinions about a range of issues related to anatomical dissection: its relative roles as the exclusive source of anatomy teaching, as a source for medical research, or to assist the future professional to acquire emotional control; the attitudes and behaviors they expect the student to have in the dissecting room; whether the student-cadaver relationship can convey knowledge and attitudes affecting the future doctor-patient relationship; and the anatomists' attitudes toward donation. Anatomists considered dissection to be mainly an instrument for professional training and to help develop professional skills. They gave little importance to the role it could play in helping students to control their emotions. However, this aspect was considered to be more important by anatomists who also valued a close doctor-patient relationship. On the other hand, a majority of anatomists felt that the student's attitude and behavior during dissection could be to some extent reflected in future relationships with patients. However, they did not feel that dissection-related attitudes would distinguish between future good or bad doctors. Finally, anatomy teachers are generally in favor of donation (86.5%), especially of organs alone (52.7%), and this aspect was not affected by their religious beliefs.     

Effects of an alternate dissection schedule on gross anatomy laboratory practical performance

The current medical curricula reform that is taking place in many medical schools throughout the world has resulted in less time for gross anatomy laboratory instruction. In response, anatomists are using a variety of approaches (e.g., peer teaching, prosections, plastinated anatomical models, etc.) to adapt to these changes. To accommodate recent curricular reform at the University of Health Sciences College of Osteopathic Medicine, an alternating dissection schedule was implemented. The purpose of this study is to examine the effects of the alternating schedule on gross anatomy laboratory practical performance. Using a Mann-Whitney Rank Sum test, back and upper limb (back-upper limb), and lower extremity laboratory practical performance for students who dissected in every laboratory (EL group; n = 227) is compared to students who dissected in every other laboratory (EOL group; n = 254). For the back-upper limb part of the anatomy laboratory practical, the mean percentage scores for the EL and EOL groups were 74.5% and 68.1%, respectively (P < 0.001). The mean percentage scores for the EL and EOL groups on the lower limb portion of the anatomy lab practical were 75.9% and 75.6%, respectively (P = 0.994). These data suggest that the use of an alternating dissection schedule had an equivocal effect on the students' gross anatomy laboratory practical performance for these two sections. The reasons for these conflicting results may have been related to regional complexity or volume of information, and the sequence in which the regions were taught.     

Comparisons between the attitudes of medical and dental students toward the clinical importance of gross anatomy and physiology

Marked changes are occurring within both the medical and dental curricula and new ways of teaching the basic sciences have been devised and traditional methods (e.g., dissection for gross anatomy and of bench‐based animal preparations for physiology) are increasingly no longer the norm. Although there is much anecdotal evidence that students are not in favor of such changes, there is little evidence for this based on quantitative analyses of students' attitudes. Using Thurstone and Chave attitude analyses, we assessed the attitudes of first year medical and dental students at Cardiff University toward gross anatomy and physiology in terms of their perceived clinical importance. In addition, we investigated the appropriateness (“fitness for purpose”) of teaching methodologies used for anatomy and physiology. The hypotheses tested recognized the possibility that medical and dental students differed in their opinions, but that they had a preference to being taught gross anatomy through the use of dissection and had no preference for physiology teaching. It was found that both medical and dental students displayed positive attitudes toward the clinical relevance of gross anatomy and that they preferred to be taught by means of dissection. Although both medical and dental students displayed positives attitudes toward the clinical relevance of physiology, this was greater for the medical students. Both medical and dental students showed a preference for being taught physiology through didactic teaching in small groups but the medical students also appreciated being taught by means of practicals. Overall, this study highlights the expectations that students have for the basic science foundation teaching within their professional training and signals a preference for being taught experientially/practically. Differences were discerned between medical and dental students that might reflect the direct association between systems physiology and pathophysiology and the application of this knowledge within the medical field in comparison to the dental field, which is heavily skill‐based.

Bodies and bureaucracy: The demise of the body snatchers in 19th century Britain

As European anatomical teaching developed in the middle ages, anatomists found themselves balanced between the educational and judicial systems. Dissection was associated with the final stages of legal prosecutions and the supply of bodies was severely limited. Driven by increasing student demand for dissection, anatomists found themselves pushed to explore alternative routes for body supply. This led to association with the developing profession of grave robber, body snatchers, and even murderers. Keen to protect themselves from increasing vulnerability to legal prosecution, the eminent anatomists of the United Kingdom pushed for government legislation to provide a supply of cadaveric material for education. This article looks at the development of the Anatomy legislation in the United Kingdom in 1832. By highlighting three events in the early 1800s, it demonstrates that the development of the legislation was for addressing the concerns of the anatomists rather than any ethical concerns about the cadaveric supply. The poorest in society were used to develop the medical understanding of the more wealthy before, during, and after the introduction of the legislation. The first event made the anatomists criminal liable for body supply while the latter two events linked anatomists with murderers. The increasing demand for legislation to provide a supply of cadaveric material released the anatomists from the financial burden of dealing with grave robbers while still allowing dissection tables to be supplied with the poorest in society.     

A change in paradigm: Giving back identity to donors in the anatomy laboratory

This article describes a paradigm of teaching in the anatomy laboratory where students interact with the families of the deceased persons whom they are dissecting. This approach focuses learning anatomy and medicine on the patient via the implementation of five guiding principles: the First Patient; Knowledge; Reflection and Reflective Practice; Treating the Total Patient; and Professionalism. Physician training typically begins with cadaveric dissection (i.e., dissection of the first patient), and therefore the medical school gross anatomy course provides an ideal environment for multifaceted educational experiences where cadaveric dissection is used to teach structure and function as well as the skills and competencies critical to patient care. Here, these principles are described, and the impact on student doctors and outcomes discussed. The results suggest that mastery of basic science knowledge and competencies, including professionalism, compassion, and leadership skill is enhanced by this protocol. Clin.

Freeze-dried specimens for gross anatomy teaching

As more and more emphasis is placed on the use of prosected specimens to support teaching and learning of gross anatomy, consideration must be given to developing new methods to preserve human cadaveric material, and in ways which will resist the wear and tear to which they are necessarily subjected. Taxidermists have developed techniques for freeze-drying whole small animals as a method of long term preservation (Metcalf, 1981). We have explored the use of this methodology to preserve small prosected specimens for use in the teaching of gross anatomy. The technique we report here was tested initially on larynges (Fig. 1) but has since been applied with equal success to other structures, including pieces of small intestine dissected to show the arterial arcades (Fig. 2). We have used material from cadavers which were preserved using our standard embalming procedure (O'Sullivan & Mitchell, 1993).     

Anatomical informatics: Millennial perspectives on a newer frontier

One of the most ancient of sciences, anatomy has evolved over many centuries. Its methods have progressively encompassed dissection instruments, manual illustration, stains, microscopes, cameras and photography, and digital imaging systems. Like many other more modern scientific disciplines in the late 20th century, anatomy has also benefited from the revolutionary development of digital computers and their automated information management and analytical capabilities. By using newer methods of computer and information sciences, anatomists have made outstanding contributions to science, medicine, and education. In that regard, there is a strong rationale for recognizing anatomical informatics as a proper subdiscipline of anatomy. A high-level survey of the field reveals important anatomical applications of computer sciences methods in imaging, image processing and visualization, virtual reality, modeling and simulation, structural database processing, networking, and artificial intelligence. Within this framework, computational anatomy is a developing field focusing on data-driven mathematical models of bodily structures. Mastering such computer sciences and informatics methods is crucial for new anatomists, who will shape the future in research, clinical knowledge, and teaching.     

New views of male pelvic anatomy: role of computer-generated 3D images

There is considerable controversy concerning the role of cadaveric dissection in teaching gross anatomy and the potential of using 3D computer-generated images to substitute for actual laboratory dissections. There are currently few high-quality 3D virtual models of anatomy available to evaluate the utility of computer-generated images. Existing 3D models are frequently of structures that are easily examined in three dimensions by removal from the cadaver, i.e., the heart, skull, and brain. We have focused on developing a 3D model of the pelvis, a region that is conceptually difficult and relatively inaccessible for student dissection. We feel students will benefit tremendously from 3D views of the pelvic anatomy. We generated 3D models of the male pelvic anatomy from hand-segmented color Visible Human Male cryosection data, reconstructed and visualized by Columbia University's in-house 3D Vesalius trade mark Visualizer.(1) These 3D models depict the anatomy of the region in a realistic true-to-life color and texture. They can be used to create 3D anatomical scenes, with arbitrary complexity, where the component anatomical structures are displayed in correct 3D anatomical relationships. Moreover, a sequence of 3D scenes can be defined to simulate actual dissection. Structures can be added in a layered sequence from the bony framework to build from the "inside-out" or disassembled much like a true laboratory dissection from the "outside-in." These 3D reconstructed anatomical models can provide views of the structures from new perspectives and have the potential to improve understanding of the anatomical relationships of the pelvic region (http://www.cellbiology.lsuhsc.edu/People/Faculty/Venuti_Figures/movie_index.html).     

Provision of anatomical teaching in a new British medical school: getting the right mix

In response to a government report, which recommended a substantial increase in the number of medical students in the United Kingdom by 2005, several new medical schools have been set up throughout the country. One such school, the Brighton and Sussex Medical School (BSMS), recently opened its doors to new students. BSMS offers a 5-year medical curriculum that uses an integrated systems-based approach to cultivate academic knowledge and clinical experience. Anatomy is one of the core elements of the program and, as such, features strongly within the modular curriculum. The challenge for the anatomy faculty has been to decide how best to integrate anatomy into the new curriculum and what teaching modalities should be used. A multidisciplinary approach has been taken using both traditional and contemporary teaching methods. Unlike most of the other new medical schools, BSMS uses cadaveric dissection as the cornerstone of its teaching, as the faculty believes that dissection still provides the most powerful technique for demonstrating anatomy as well as enhancing communication and teamwork skills. The dissection experience is handled using an understanding and professional way. However, to ensure that our students do not become detached from the process of patient-focused care, emphasis in the dissecting room environment is also placed on respect and compassion. To enhance conceptual understanding of structure and function and provide further clinical relevance, we are using imaging technology to demonstrate living anatomy. Unique to the BSMS curriculum is the teaching of the anatomy in the later years of the program. During specialist rotations, students will return to the dissecting room to study the anatomy relevant to that area. Such vertical integration ensures that core anatomical knowledge is gained at the most appropriate level relative to a student's clinical experience.     

Collaborative learning using Internet2 and remote collections of stereo dissection images

We have investigated collaborative learning of anatomy over Internet2, using an application called remote stereo viewer (RSV). This application offers a unique method of teaching anatomy, using high-resolution stereoscopic images, in a client-server architecture. Rotated sequences of stereo image pairs were produced by volumetric rendering of the Visible female and by dissecting and photographing a cadaveric hand. A client-server application (RSV) was created to provide access to these image sets, using a highly interactive interface. The RSV system was used to provide a "virtual anatomy" session for students in the Stanford Medical School Gross Anatomy course. The RSV application allows both independent and collaborative modes of viewing. The most appealing aspects of the RSV application were the capacity for stereoscopic viewing and the potential to access the content remotely within a flexible temporal framework. The RSV technology, used over Internet2, thus serves as an effective complement to traditional methods of teaching gross anatomy.     

Gross anatomy course content and teaching methodology in allied health: clinicians' experiences and recommendations

The purpose of this study was to sample the experiences and recommendations of clinicians in allied health fields about gross anatomy courses. The objective was to determine if practicing clinicians recommended a course in gross anatomy, and, if so, their recommendations for course content and teaching methodology. Questionnaires were mailed to a random selection of occupational therapists (OTs), physician assistants (PAs), and physical therapists (PTs) licensed in the state of Texas. In addition to demographics, the survey asked 14 questions regarding the experiences and recommendations in seven areas of interest about gross anatomy courses. The responding sample appeared to be representative of the target population. A course in human gross anatomy during professional school was recommended by 96% of OTs, and 100% of PAs and PTs. The single most recommended teaching method was student dissection of human cadavers. Although significant differences were found regarding primary course orientation, a majority favored some form of combined systems and regional oriented courses. A majority of clinicians in each field recommended a gross anatomy course at the beginning of professional training. Specific recommendations were given for content of systems and regional oriented gross anatomy courses. We recommend that the gross anatomy course content and teaching methodologies in allied health areas be responsive to the specific needs of each clinical specialty. Copyright Wiley-Liss, Inc.     

Advance organizers in a gross anatomy dissection course and their effects on academic achievement

We presented two kinds of advance organizers (AOs), video clips and prosection, for a gross anatomy dissection course and compared their effects on academic achievement and student perception of the learning experience. In total, 141 students at Chonnam National University Medical School were randomly assigned to two groups: Group 1 (n = 70) was provided with video clips AO, whereas Group 2 (n = 71) was provided with prosection AO, the use of cadaveric specimens dissected by the course instructor. Student self‐assessment scores regarding the learning objectives of upper limb anatomy improved significantly in both groups. Academic achievement scores in Group 2 were significantly higher than those in Group 1, although the self‐assessment scores were not significantly different between the groups. Additionally, students in Group 2 responded significantly more positively to the statements about perception of the learning experience such as helping them understand the course content and concepts, decreasing anxiety about the dissection course, and participating actively in the dissection. It would seem that the application of prosection as an AO improved academic achievement and increased student engagement and satisfaction. This study will contribute to designing effective AOs and developing a teaching and learning strategy for a gross anatomy dissection course. Clin. Anat. 2013. © 2012 Wiley Periodicals, Inc.     

The use of plastinated prosections for teaching anatomy--the view of medical students on the value of this learning resource

Over the past decade, the role of anatomical teaching in the undergraduate medical curriculum has changed considerably. At some medical schools, active dissection of cadaveric specimens is gradually being replaced by prosection-based methods and other resources such as e-learning. Warwick Medical School has recently obtained a large collection of plastinated prosections, which replace wet cadaveric specimens in undergraduate anatomy teaching. The aim of this study was to examine students' views on the use of plastinated prosections for their anatomical learning. A mixed method approach was employed using a questionnaire and focus group for data collection. The questionnaire was completed by 125 first-year medical students (response rate 68%). The majority of students (94%) rated plastinated prosections as a valuable resource for their anatomical learning. Various features of the specimens were highlighted, such as the detailed view of relevant anatomy, appreciation of relations between structures, and visualization of anatomy in real life. However, learning on plastinated prosections was perceived to be compromised because of limitations in terms of tactile and emotional experience. We conclude that plastinated prosections are an adequate resource for the early stages of undergraduate training, but that the learning experience may be further enhanced by providing opportunity for the study of wet cadaveric material.     

Changing anatomy education and introduction of self assessment of teacher performance in Japan.

The current curriculum reform is directed toward improvement of students' ability of clinical practice in primary care, and a substantial system of bedside learning is being extensively explored. Introduction of clinical clerkship necessarily forces qualitative changes in the teaching of basic medical sciences. A large number of Japanese medical schools is now attempting to establish a new educational system that makes it possible to change from "didactic education" by lectures and laboratory studies to "self learning education" by means of tutorials and other systems. In this context, Japanese anatomists are urgently requested to develop new and effective clinically oriented educational systems in teaching gross anatomy as a shift from the traditional teaching as a science of morphology. Evaluation of faculty staff's teaching achievement is about to start in many medical schools. Research activities can be evaluated quantitatively. In contrast, measurement of educational activities of faculty staff is very difficult, and all medical schools are devoted to construct effective and liable systems. Anatomy faculty is obliged to devote more time than that of other disciplines in education-related activities such as cadaver collection and associated business. How to evaluate adequately these invisible activities is an issue to be solved before the introduction of a self assessment system. Successful solutions to these issues are critical for production of future anatomists.     

On behalf of tradition: An analysis of medical student and physician beliefs on how anatomy should be taught

Human anatomy, one of the basic medical sciences, is a time‐honored discipline. As such, it is taught using traditional methods, cadaveric dissection chief among them. Medical imaging has recently gained popularity as a teaching method in anatomy courses. In light of a general tendency to reduce course hours, this has resulted in a decrease of dissection time and intense debates between traditional and modern approaches to anatomy teaching. In an attempt to explore trends in the attitudes of medical professionals toward the various methods of anatomy teaching, medical imaging in particular, the authors constructed a questionnaire and conducted a nationwide survey among medical students (in all stages at medical school), residents, and specialists in all fields of medicine. The survey results demonstrated indisputable appreciation of traditional methods of anatomy teaching, particularly cadaveric dissection, and showed that specialists believe significantly more strongly than clinical or preclinical students that anatomy and medical imaging should be taught separately. Strong correlations among the components of the traditional approach to anatomy instruction were also found. In light of the results, it was recommended that imaging should be incorporated into anatomy courses with caution, and, as far as possible, not at the expense of dissection time. It was advised that medical imaging has to be taught as a separate course, parallel to a traditional anatomy course. This will allow anatomical principles to be appreciated, which in turn will serve the students when they study radiology. “And we proceed in the following order: in front walks Nikolai with the slides or atlases, I come after him, and after me, his head humbly lowered, strides the cart horse; or else, if necessary, a cadaver is carried in first, after the cadaver walks Nikolai, and so on. At my appearance, the students rise, then sit down, and the murmur of the sea suddenly grows still. Calm ensues.” —From “A Boring Story: From the Notebook of an Old Man” by Anton Chekhov. Clin.
