The concept that multisensory observation and drawing can be effective for enhancing anatomy learning is supported by pedagogic research and theory, and theories of drawing. A haptico-visual observation and drawing (HVOD) process has been previously introduced to support understanding of the three-dimensional (3D) spatial form of anatomical structures. The HVOD process involves exploration of 3D anatomy with the combined use of touch and sight, and the simultaneous act of making graphite marks on paper which correspond to the anatomy under observation. Findings from a previous study suggest that HVOD can increase perceptual understanding of anatomy through memorization and recall of the 3D form of observed structures. Here, additional pedagogic and cognitive underpinnings are presented to further demonstrate how and why HVOD can be effective for anatomy learning. Delivery of a HVOD workshop is described as a detailed guide for instructors, and themes arising from a phenomenological study of educator experiences of the HVOD process are presented. Findings indicate that HVOD can provide an engaging approach for the spatial exploration of anatomy within a supportive social learning environment, but also requires modification for effective curricular integration. Consequently, based on the most effective research-informed, theoretical, and logistical elements of art-based approaches in anatomy learning, including the framework provided by the observe–reflect–draw–edit–repeat (ORDER) method, an optimized “ORDER Touch” observation and drawing process has been developed. This is with the aim of providing a widely accessible resource for supporting social learning and 3D spatial understanding of anatomy, in addition to improving specific anatomical knowledge.  相似文献

Medical schools are increasingly integrating professionalism training into their gross anatomy courses, teaching ethical behavior and humanistic attitudes through the dissection experience. However, many schools continue to take a traditional, technical approach to anatomical education while teaching professionalism in separate courses. This interview-based study explored how students viewed the body donor and the professional lessons they learned through dissection at one such medical school. All students oscillated involuntarily between seeing the cadaver as a specimen for learning and seeing the cadaver as a person, with some students intentionally cultivating one of these ways of seeing over the other. These views shaped students’ emotional and moral responses to the experiences of dissection. The “specimen” view facilitated a technical, detached approach to dissection, while the “person” view made students engage emotionally. Further, students who intentionally cultivated a “specimen” view generally felt less moral distress about dissection than students who intentionally cultivated a “person” view. The concept of respect gave students permission to perform dissections, but “person-minded” students developed more complex rules around what constituted respectful behavior. Both groups of students connected the gross anatomy experience to their professional development, but in different ways. “Specimen-minded” students intentionally objectified the body to learn the emotional control physicians need, while “person-minded” students humanized the body donor to promote the emotional engagement required of physicians. These findings support efforts to integrate professionalism teaching into gross anatomy courses, particularly content, addressing the balance between professional detachment and concern.  相似文献

The preclinical compulsory elective course “Ready for the Operating Room (OR)!?” [in German]: “Fit für den OP (FOP)”] was implemented for students in their second year, who were simultaneously enrolled in the gross anatomy course. The objective of the study was to determine whether the direct practical application of anatomical knowledge within the surgical context of the course led to any improvement in learning motivation, learning orientation, and ultimately examination results in the gross anatomy course, as compared with a control group. Within the scope of five teaching sessions, the students learned surgical hand disinfection, suturing techniques, and the identification of commonly used surgical instruments. In addition, the students attended five surgical demonstrations performed by surgical colleagues on cadavers. Successful learning of these basic skills was then assessed based on an Objectively Structured Practical Examination. Learning motivation and learning orientation in both subgroups was determined using the SELLMO‐ST motivation test and the Approaches and Study Skills Inventory test. While a significant increase in work avoidance was identified in the control group, this was not the case for FOP participants. Similarly, an increase in the “deep approach” to learning, as well as a decrease in the “surface approach,” was able to be documented among the FOP participants following completion of the course. The results suggest that students enrolled in the gross anatomy course, who were simultaneously provided with the opportunity to learn in clinical context, were more likely to be successful at maintaining learning motivation and learning orientation required for the learning process, than students who attended the gross anatomy course alone.

In contrast to medical education, information on the use of arts as a learning approach is scarce in veterinary anatomy. The aim of this prospective, questionnaire-based study was to survey students' use of drawing in various aspects of veterinary anatomy learning (self-study, examinations, preparation for, and reflection on cadaver dissection). The quantitative data showed that first-year students with artistic preferences used drawing significantly more often in most aspects of anatomy learning than students with no such preferences, apart from the reported use of drawing in examinations and for reflection after cadaver dissection. The lack of significant correlations of the reported use of drawing in examinations with any other study variable provided support for the author's observation that student-generated drawings are not as commonly used in examinations as previously. In contrast to the study hypothesis, previous university studies did not correlate significantly with any aspect of the use of drawing in anatomy learning. None of the reported uses of drawing addressed the benefits of drawing in learning the comparative anatomy of animal species, a characteristic distinguishing veterinary anatomy from human anatomy. Qualitative student feedback indicated that encouragement and teacher-produced images would increase the use of drawing as a learning approach even if the implementation of drawing into the curriculum is not feasible. Conclusions from this study were implemented through self-directed learning in anatomy courses that replaced the canceled cadaveric dissections during the COVID-19 outbreak and also through the ongoing drawing workshops to further advance the use of drawing in veterinary anatomy learning.  相似文献

This study evaluates a cooperative learning approach for teaching anatomy to health science students incorporating small group and peer instruction based on the jigsaw method first described in the 1970's. Fifty-three volunteers participated in abdominal anatomy workshops. Students were given time to become an “expert” in one of four segments of the topic (sub-topics) by allocating groups to work-stations with learning resources: axial computerized tomography (CT) of abdominal structures, axial CT of abdominal blood vessels, angiograms and venograms of abdominal blood vessels and structures located within abdominal quadrants. In the second part of workshop, students were redistributed into “jigsaw” learning groups with at least one “expert” at each workstation. The “jigsaw” learning groups then circulated between workstations learning all sub-topics with the “expert” teaching others in their group. To assess abdominal anatomy knowledge, students completed a quiz pre- and post- workshop. Students increased their knowledge with significant improvements in quiz scores irrespective of prior exposure to lectures or practical classes related to the workshop topic. The evidence for long-term retention of knowledge, assessed by comparing end-semester examination performance of workshop participants with workshop nonparticipants, was less convincing. Workshop participants rated the jigsaw workshop highly for both educational value and enjoyment and felt the teaching approach would improve their course performance. The jigsaw method improved anatomy knowledge in the short-term by engaging students in group work and peer-led learning, with minimal supervision required. Reported outcomes suggest that cooperative learning approaches can lead to gains in student performance and motivation to learn.

Changes in medical education have affected both curriculum design and delivery. Many medical schools now use integrated curricula and a systemic approach, with reduced hours of anatomy teaching. While learning anatomy via dissection is invaluable in educational, professional, and personal development, it is time intensive and supports a regional approach to learning anatomy; the use of prosections has replaced dissection as the main teaching method in many medical schools. In our graduate‐entry medical degree, we use an integrated curriculum, with prosections to teach anatomy systemically. However, to not exclude dissection completely, and to expose students to its additional and unique benefits, we implemented a short “Dissection Experience” at the beginning of Year 2. Students attended three two‐hour anatomy sessions and participated in dissection of the clinically relevant areas of the cubital fossa, femoral triangle, and infraclavicular region. This activity was voluntary and we retrospectively surveyed all students to ascertain factors influencing their decision of whether to participate in this activity, and to obtain feedback from those students who did participate. The main reasons students did not participate were previous dissection experience and time constraints. The reasons most strongly affecting students' decisions to participate related to experience (lack of previous or new) and new skill. Students' responses as to the most beneficial component of the dissection experience were based around practical skills, anatomical education, the learning process, and the body donors. We report here on the benefits and practicalities of including a short dissection experience in a systemic, prosection‐based anatomy course.

Understanding basic human anatomy can be beneficial for all students, regardless of when, or if, they will later undertake a formal course in the subject. For students who are preparing to undertake a formal anatomy course, educational comics on basic anatomy can serve as a concise and approachable review of the material. For other students, these comics can serve as a helpful and fun introduction to the human body. The objective of the comics in this study was to promote an understanding of fundamental human anatomy through self‐learning among students. Based on the authors' previous teaching experience, these anatomy comics were produced in a simple, direct style. The comics were titled after the two main characters, “Anna” (a girl) and “Tommy” (a boy). These comics were then presented to groups of elementary school students, high school students, premedical students, and medical students to assess the comics' ability to enhance student interest and comprehension of basic anatomy. Quiz scores among high school students and premedical students were significantly higher among participants who read the educational comics, indicating a deeper comprehension of the subject. Among medical students, close reading of the comics was associated with improved course grades. These educational anatomy comics may be helpful tools to enrich a broad spectrum of different students in learning basic human anatomy.

Recognition of anatomical landmarks in live animals (and humans) is key for clinical practice, but students often find it difficult to translate knowledge from dissection‐based anatomy onto the live animal and struggle to acquire this vital skill. The purpose of this study was to create and evaluate the use of an equine anatomy rug (“Anato‐Rug”) depicting topographical anatomy and key areas of lung, heart, and gastrointestinal auscultation, which could be used together with a live horse to aid learning of “live animal” anatomy. Over the course of 2 weeks, 38 third year veterinary students were randomly allocated into an experimental group, revising topographical anatomy from the “Anato‐Rug,” or a control group, learning topographical anatomy from a textbook. Immediately post activity, both groups underwent a test on live anatomy knowledge and were retested 1 week later. Both groups then completed a questionnaire to ascertain their perceptions of their learning experiences. Results showed that the experimental groups scored significantly higher than the control group at the first testing session, experienced more enjoyment during the activity and gained more confidence in identifying anatomical landmarks than the control group. There was not a significant difference in scores between groups at the second testing session. The findings indicate that the anatomy rug is an effective learning tool that aids understanding, confidence, and enjoyment in learning equine thorax and abdominal anatomy; however it was not better than traditional methods with regards to longer term memory recall.

Recently, faculty at Pritzker School of Medicine, The University of Chicago, have made efforts to improve the depth of radiological anatomy knowledge that students have, but no insights exist as to student and resident opinions of how clinically helpful deep anatomical understanding is. A single‐institution survey of second‐ and fourth‐year medical students and postgraduate year 1–4 residents from 11 specialties, composed of five‐point Likert questions, sample examination questions, and narrative response questions, was distributed in 2015. One hundred seventy‐seven of the 466 potential respondents replied (71 residents and 106 students), response rate 38.0%. No nonresponse bias was present in two separate analyses. Respondents generally favored a superficial “identification” question as more relevant to clinical practice, which was positively associated with increasing clinical experience ρ = 0.357, P < 0.001 by point‐biserial correlation. Students and residents most commonly used self‐directed methods to learn medical imaging during their medical anatomy courses (72.6 and 57.7%, respectively). Small group education was least commonly used by students and residents (45.3 and 39.4%, respectively), but most commonly recommended (62.3 and 69%, respectively). A total of 56.6 and 64.8% of students and residents, respectively, reported that having multiple learning methods was “quite” or “extremely” important. Respondents with more clinical experience were more likely to report that a superficial identification question was more clinically relevant than a question testing deeper radiological anatomy knowledge. Small group learning was preferred among students and residents but was the least commonly employed method of instruction. Both findings contrast starkly with current radiological anatomy instructional understanding and practices. Anat Sci Educ 11: 25–31. © 2017 American Association of Anatomists.  相似文献

Gross anatomy dissection in contemporary medical education must balance the traditional value of learning from the cadaver with the possibilities created by the use of digital tools as supplemental resources that personalize and deepen the student learning experience. This study broadly examined the design, implementation, and use of AnatomyShare, a novel iPad application employing learner-generated content that allows students to securely share annotated images of their dissections with each other and take faculty-generated image-based quizzes during their first-year medical school gross anatomy course. Almost all students enrolled in the course used the application (N = 176; 91% use based on analytics). Seventy-five students responded to a survey asking how and when they used the application, along with their perceptions of its usefulness and contribution to learning. More students reported using the application outside of laboratory (97.3%) than during laboratory (85.3%), despite only in-laboratory use being required. Taking quizzes using the “Exam” feature was the highest rated use of AnatomyShare, and students cited that the application exposed them to anatomical variation and motivated them to correctly identify structures during dissection. While steps need to be taken to combat low-quality learner-generated content and to enhance meaningful student interaction and collaboration, AnatomyShare was a feasible and highly rated supplement to dissection that provided valuable assessment opportunities for students. Future research will examine the impact of use on course grades and engagement in gross anatomy dissection.  相似文献

Dissection is a unique multisensory educational experience and is essential to learning the anatomical construction of the human and animal bodies. This study aims to introduce a specialized design for the assessment of dissection and to discuss the assessment's attributes. The design was a product of the “assessment drives learning” concept and was developed to motivate students to dissect. Students were awarded “dissection points” based on prior group dissection and identification of structures. Students' perception of the design was examined, and content analysis was performed. The assessment consisted of two parts: the first assigning each student group structures to “pin” on their previously dissected cadavers; the second was a group peer evaluation. The most critical factor for the assessment's success was careful selection of structures assigned to students to pin. The assessment was fit for the purpose, valid, reliable, and had a significant educational impact. Eighty-three percent of students (n = 116) recommended maintaining the assessment design, as they felt it promoted a deep approach to learning as well as teamwork while reducing stress to a minimum. A strong correlation (Spearman's rho = 0.46, P < 0.0001) was present between the high rating of the design and the number of structures learned, as well as, high rating and lower stress level (Spearman's rho = 0.40, P < 0.0001). There was no apparent influence of grades on student perception of the effectiveness of the assessment. This specific design of evaluation could be used as part of anatomy education in veterinary and medical schools.  相似文献

Increasing number of medical students and limited availability of cadavers have led to a reduction in anatomy teaching through human cadaveric dissection. These changes triggered the emergence of innovative teaching and learning strategies in order to maximize students learning of anatomy. An alternative approach to traditional dissection was presented in an effort to improve content delivery and student satisfaction. The objective of this study is to acquire three-dimensional (3D) anatomical data using structured-light surface scanning to create a dynamic four-dimensional (4D) dissection tool of four regions: neck, male inguinal and femoral areas, female perineum, and brachial plexus. At each dissection step, identified anatomical structures were scanned using a 3D surface scanner (Artec Spider™). Resulting 3D color meshes were overlaid to create a 4D (3D+time) environment. An educational interface was created for neck dissection. Its implementation in the visualization platform allowed 4D virtual dissection by navigating from surface to deep layers and vice versa. A group of 28 second-year medical students and 17 first-year surgery residents completed a satisfaction survey. A majority of medical students (96.4%) and 100% of surgery residents said that they would recommend this tool to their colleagues. According to surgery residents, the main elements of this virtual tool were the realistic high-quality of 3D acquisitions and possibility to focus on each anatomical structure. As for medical students, major elements were the interactivity and entertainment aspect, precision, and accuracy of anatomical structures. This approach proves that innovative solutions to anatomy education can be found to help to maintain critical content and student satisfaction in anatomy curriculum.  相似文献

Teaching internal structures obscured from direct view is a major challenge of anatomy education. High-fidelity interactive three-dimensional (3D) micro-computed tomography (CT) models with virtual dissection present a possible solution. However, their utility for teaching complex internal structures of the human body is unclear. The purpose of this study was to investigate the use of a realistic 3D micro-CT interactive visualization computer model to teach paranasal sinus anatomy in a laboratory setting during pre-clinical medical training. Year 1 (n = 79) and Year 2 (n = 59) medical students undertook self-directed activities focused on paranasal sinus anatomy in one of two laboratories (traditional laboratory and 3D model). All participants completed pre and posttests before and after the laboratory session. Results of regression analyses predicting post-laboratory knowledge indicate that, when students were inexperienced with the 3D computer technology, use of the model was detrimental to learning for students with greater prior knowledge of the relevant anatomy (P < 0.05). For participants experienced with the 3D computer technology, however, the use of the model was detrimental for students with less prior knowledge of the relevant anatomy (P < 0.001). These results emphasize that several factors need to be considered in the design and effective implementation of such models in the classroom. Under the right conditions, the 3D model is equal to traditional laboratory resources when used as a learning tool. This paper discusses the importance of preparatory training for students and the technical consideration necessary to successfully integrate such models into medical anatomical curricula.  相似文献

Early exposure to radiological cross-section images during introductory anatomy and dissection courses increases students’ understanding of both anatomy and radiology. Novel technologies such as augmented reality (AR) offer unique advantages for an interactive and hands-on integration with the student at the center of the learning experience. In this article, the benefits of a previously proposed AR Magic Mirror system are compared to the Anatomage, a virtual dissection table as a system for combined anatomy and radiology teaching during a two-semester gross anatomy course with 749 first-year medical students, as well as a follow-up elective course with 72 students. During the former, students worked with both systems in dedicated tutorial sessions which accompanied the anatomy lectures and provided survey-based feedback. In the elective course, participants were assigned to three groups and underwent a self-directed learning session using either Anatomage, Magic Mirror, or traditional radiology atlases. A pre- and posttest design with multiple choice questions revealed significant improvements in test scores between the two tests for both the Magic Mirror and the group using radiology atlases, while no significant differences in test scores were recorded for the Anatomage group. Furthermore, especially students with low mental rotation test (MRT) scores benefited from the Magic Mirror and Anatomage and achieved significantly higher posttest scores compared to students with a low MRT score in the theory group. Overall, the results provide supporting evidence that the Magic Mirror system achieves comparable results in terms of learning outcome to established anatomy learning tools such as Anatomage and radiology atlases.  相似文献

Many institutions rely upon prosection-based laboratories as more resource-efficient and time-effective alternatives to traditional cadaver dissection for human anatomy education. To facilitate growing enrollment numbers despite resource limitations, the University of Guelph (a non-medical institution) introduced a modified “stepwise” prosection-based laboratory cohort to supplement a dissection-based course. In this design, all students attended the same lectures, but those in the dissection-based cohort learned by performing regional dissections and students in the prosection-based cohort studied from those dissections. Prosection students thereby witnessed a “slow reveal” of structures throughout the course. This study compared the perceived course experiences, student approaches to learning, and academic performance between the two groups. Multiple linear regression analyses were used to isolate the effect of the laboratory environment on student approaches to learning and academic performance from demographic and situational covariates. Both groups reported positive course experience ratings and high average final grades that were not statistically dissimilar (P > 0.05), increased reliance on deep approaches to learning (P = 0.002), and decreased reliance on surface approaches to learning (P = 0.023). When controlling for covariates, participation in dissection had small but statistically significant positive associations with deep approaches to learning (P = 0.043), performance on laboratory oral assessments (P < 0.001), and average final grades (P = 0.039). Ultimately, both designs promoted meaningful learning and desirable performance outcomes, indicating that both dissection and stepwise prosection have the potential to facilitate high quality human anatomy instruction.  相似文献

In general, mathematical representations such as formulae, numbers, and graphs are the inseparable components in science used to better describe or explain scientific phenomena or knowledge. Regardless of their necessity and benefit, science seems to be difficult for some students, as a result of the mathematical representations and problem solving used in scientific inquiry. In this regard, several studies have attributed students’ decreasing interest in science to the presence of these mathematical representations. In order to better understand student learning difficulties caused by mathematical components, the current study investigates student understanding of a familiar science concept and its mathematical component (pH value and logarithms). Student responses to a questionnaire and a follow-up interview were examined in detail. “Measure” and “concentration” were key criteria for students’ understanding of pH values. In addition, only a few students understood logarithms on a meaningful level. According to students’ understanding of scientific phenomena and mathematical structures, five different student models and the critical features of each type were identified. Further analysis revealed the existence of three domains that characterize these five types: object, operation, and function. By suggesting the importance of understanding scientific phenomena as a “function,” the current study reveals what needs to be taught and emphasized in order to help students obtain a level of scientific meaning that is appropriate for their grade.  相似文献

Ultrasonography is increasingly used in medical education, but its impact on learning outcomes is unclear. Adding ultrasound may facilitate learning, but may also potentially overwhelm novice learners. Based upon the framework of cognitive load theory, this study seeks to evaluate the relationship between cognitive load associated with using ultrasound and learning outcomes. The use of ultrasound was hypothesized to facilitate learning in anatomy for 161 novice first‐year medical students. Using linear regression analyses, the relationship between reported cognitive load on using ultrasound and learning outcomes as measured by anatomy laboratory examination scores four weeks after ultrasound‐guided anatomy training was evaluated in consenting students. Second anatomy examination scores of students who were taught anatomy with ultrasound were compared with historical controls (those not taught with ultrasound). Ultrasound's perceived utility for learning was measured on a five‐point scale. Cognitive load on using ultrasound was measured on a nine‐point scale. Primary outcome was the laboratory examination score (60 questions). Learners found ultrasound useful for learning. Weighted factor score on “image interpretation” was negatively, but insignificantly, associated with examination scores [F (1,135) = 0.28, beta = ?0.22; P = 0.61]. Weighted factor score on “basic knobology” was positively and insignificantly associated with scores; [F (1,138) = 0.27, beta = 0.42; P = 0.60]. Cohorts exposed to ultrasound had significantly higher scores than historical controls (82.4% ± SD 8.6% vs. 78.8% ± 8.5%, Cohen's d = 0.41, P < 0.001). Using ultrasound to teach anatomy does not negatively impact learning and may improve learning outcomes. Anat Sci Educ 10: 144–151. © 2016 American Association of Anatomists.  相似文献

Areas of difficulty faced by our veterinary medicine students, with respect to their learning in dissection classes, were identified. These challenges were both general adult‐learning related and specific to the discipline of anatomy. Our aim was to design, implement, and evaluate a modified reciprocal peer‐assisted/team‐based learning format—Doing Dissections Differently (DDD)—to complement existing dissection classes, with the intention of enhancing both student learning and the student learning experience. Second year veterinary medicine students (n = 193), in their usual dissection groups, were randomly assigned to one of four roles: anatomist, clinician, radiologist, and learning resources manager. Students attended a preparatory workshop outlining the skills required for effective execution of their role. They were then asked to perform their roles throughout five consecutive musculoskeletal dissection classes. Student attitudes to dissection classes before and after DDD were evaluated by questionnaire (146 respondents). There was a significant (P = 0.0001) improvement after DDD in a number of areas: increased perceived value of dissection classes as an anatomy learning aid; improved appreciation of the clinical relevance of anatomy; increased use of resources before and during dissection classes; and longer preparation time for dissection classes. Before DDD, 45% of students felt that at least one peer did not contribute usefully to the group during dissection classes; no improvement was seen in this measure after DDD. Although the new format highlighted a potential need to improve teamwork, most students actively engaged with DDD, with dissection classes valued more highly and utilized more effectively. © 2012 American Association of Anatomists.  相似文献

It is essential for medical students to learn and comprehend human anatomy in three dimensions (3D). With this in mind, a new system was designed in order to integrate anatomical dissections with diagnostic computed tomography (CT) radiology. Cadavers were scanned by CT scanners, and students then consulted the postmortem CT images during cadaver dissection to gain a better understanding of 3D human anatomy and diagnostic radiology. Students used handheld digital imaging and communications in medicine viewers at the bench‐side (OsiriX on iPod touch or iPad), which enabled “pixel‐to‐tissue” direct comparisons of CT images and cadavers. Students had lectures and workshops on diagnostic radiology, and they completed study assignments where they discussed findings in the anatomy laboratory compared with CT radiology findings. This teaching method for gross and radiological anatomy was used beginning in 2009, and it yielded strongly positive student perspectives and significant improvements in radiology skills in later clinical courses.
