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.

Utilizing reality anatomy such as dissection and demonstrating using cadavers has been described as a superior way to create meaning. The chemicals used to embalm cadavers differentially alter the tissue of the human body, which has led to the usage of different processes along the hard to soft‐fixed spectrum of preserved cadavers. A questionnaire based approach was used to gain a better insight into the opinion of anatomists on the use of preserved cadavers for the teaching of human anatomy. This study focused on anatomy teachers in the United Kingdom and Ireland. From the 125 participating anatomists, 34.4% were medically qualified, 30.4% had a PhD in a non‐anatomical science and 22.4% had a PhD in an anatomical science, these figures include ten anatomists who had combinations of MD with the two other PhD qualifications. The main findings from the questionnaire were that 61.6% of participants agreed that hard‐fixed formalin cadavers accurately resemble features of a human body whereas 21.6% disagreed. Moreover, anatomists rated the teaching aids on how accurately they resemble features of the human body as follows: plastic models the least accurate followed by plastinated specimens, hard fixed cadavers; soft preserved cadavers were considered to be the most accurate when it comes to resembling features of the human body. Though anatomists considered soft preserved cadavers as the most accurate tool, further research is required in order to investigate which techniques or methods provide better teaching tool for a range of anatomical teaching levels and for surgical training.

The teaching of anatomy has consistently been the subject of societal controversy, especially in the context of employing cadaveric materials in professional medical and allied health professional training. The reduction in dissection‐based teaching in medical and allied health professional training programs has been in part due to the financial considerations involved in maintaining bequest programs, accessing human cadavers and concerns with health and safety considerations for students and staff exposed to formalin‐containing embalming fluids. This report details how additive manufacturing or three‐dimensional (3D) printing allows the creation of reproductions of prosected human cadaver and other anatomical specimens that obviates many of the above issues. These 3D prints are high resolution, accurate color reproductions of prosections based on data acquired by surface scanning or CT imaging. The application of 3D printing to produce models of negative spaces, contrast CT radiographic data using segmentation software is illustrated. The accuracy of printed specimens is compared with original specimens. This alternative approach to producing anatomically accurate reproductions offers many advantages over plastination as it allows rapid production of multiple copies of any dissected specimen, at any size scale and should be suitable for any teaching facility in any country, thereby avoiding some of the cultural and ethical issues associated with cadaver specimens either in an embalmed or plastinated form.

Hands‐on educational experiences can stimulate student interest, increase knowledge retention, and enhance development of clinical skills. The Lachman test, used to assess the integrity of the anterior cruciate ligament (ACL), is commonly performed by health care professionals and is relatively easy to teach to first‐year health profession students. This study integrated teaching the Lachman test into a first‐year anatomy laboratory and examined if students receiving the training would be more confident, competent, and if the training would enhance anatomical learning. First‐year medical, physician assistant and physical therapy students were randomly assigned into either the intervention (Group A) or control group (Group B). Both groups received the course lecture on knee anatomy and training on how to perform the Lachman test during a surface anatomy class. Group A received an additional 15 minutes hands‐on training for the Lachman test utilizing a lightly embalmed cadaver as a simulated patient. One week later, both groups performed the Lachman test on a lightly embalmed cadaver and later completed a post‐test and survey. Students with hands‐on training performed significantly better than students with lecture‐only training in completing the checklist, a post‐test, and correctly diagnosing an ACL tear. Students in Group A also reported being more confident after hands‐on training compared to students receiving lecture‐only training. Both groups reported that incorporating clinical skill activities facilitated learning and created excitement for learning. Hands‐on training using lightly embalmed cadavers as patient simulators increased confidence and competence in performing the Lachman test and aided in learning anatomy.

The purpose of this study was to examine the histopathologic reliability of embalmed cadaveric tissue taken from the gross anatomy laboratory. Tissue samples from hearts, livers, lungs, and kidneys were collected after the medical students’ dissection course was completed. All of the cadavers were embalmed in a formalin‐based fixative solution. The tissue was processed, embedded in paraffin, sectioned at six micrometers, and stained with H&E. The microscope slides were evaluated by a board certified pathologist to determine whether the cellular components of the tissues were preserved at a high enough quality to allow for histopathologic diagnosis. There was a statistically significant relationship between ratings and organ groups. Across all organs, there was a smaller proportion of “poor” ratings. The lung group had the highest percentage of “poor” ratings (23.1%). The heart group had the least “poor” ratings (0.0%). The largest percentage of “satisfactory” ratings were in the lung group (52.8%), and the heart group contained the highest percentage of “good” ratings (58.5%) The lung group had the lowest percentage of “good” ratings (24.2%). These results indicate that heart tissue is more reliable than lung, kidney, or liver tissue when utilizing tissue from the gross anatomy laboratory for research and/or educational purposes. This information advises educators and researchers about the quality and histopathologic reliability of tissue samples obtained from the gross anatomy laboratory.

Interprofessional education (IPE) in clinical practice is believed to improve outcomes in health care delivery. Integrating teaching and learning objectives through cross discipline student interaction in basic sciences has the potential to initiate interprofessional collaboration at the early stages of health care education. Student attitudes and effectiveness of IPE in the context of a combined gross anatomy course for first‐year students in Doctor of Physical Therapy (DPT) and Doctor of Medicine (MD) degrees curricula were evaluated. Integrated teams of MD and DPT students participated in part of the gross anatomy dissection course at Mayo Medical School. A survey was administered to 42 MD and 28 DPT students that assessed their attitudes toward IPE and cooperation among health care professionals. Pre‐ and post‐experience surveys were evaluated. Positive comments were related to opportunities for developing a better understanding of the nature and scope of each other's programs, encouraging teamwork and communication, mutual respect, and reducing the perceptual divide between disciplines. Ninety‐two percent of the students agreed that interprofessional learning would help them in becoming a more effective member of the health care team. This initial experience with IPE in gross anatomy provides a basis for continued development of interdisciplinary educational strategies.

Understanding the three‐dimensional (3D) nature of the human form is imperative for effective medical practice and the emergence of 3D printing creates numerous opportunities to enhance aspects of medical and healthcare training. A recently deceased, un‐embalmed donor was scanned through high‐resolution computed tomography. The scan data underwent segmentation and post‐processing and a range of 3D‐printed anatomical models were produced. A four‐stage mixed‐methods study was conducted to evaluate the educational value of the models in a medical program. (1) A quantitative pre/post‐test to assess change in learner knowledge following 3D‐printed model usage in a small group tutorial; (2) student focus group (3) a qualitative student questionnaire regarding personal student model usage (4) teaching faculty evaluation. The use of 3D‐printed models in small‐group anatomy teaching session resulted in a significant increase in knowledge (P = 0.0001) when compared to didactic 2D‐image based teaching methods. Student focus groups yielded six key themes regarding the use of 3D‐printed anatomical models: model properties, teaching integration, resource integration, assessment, clinical imaging, and pathology and anatomical variation. Questionnaires detailed how students used the models in the home environment and integrated them with anatomical learning resources such as textbooks and anatomy lectures. In conclusion, 3D‐printed anatomical models can be successfully produced from the CT data set of a recently deceased donor. These models can be used in anatomy education as a teaching tool in their own right, as well as a method for augmenting the curriculum and complementing established learning modalities, such as dissection‐based teaching.

Allied health professionals concur that a sound knowledge of practical gross anatomy is vital for the clinician, however, human anatomy courses in allied health programs have been identified as high‐risk for attrition and failure. While anatomists and clinicians agree that learning anatomy via human cadaveric instruction is the preferred method, students vary in their reaction to the cadaveric learning experience and have differing levels of anatomy self‐efficacy. This study investigated whether student self‐efficacy had an effect on student usage of supplemental instructional videos and whether the use of videos had an impact on student self‐efficacy and/or learning. Anatomy self‐efficacy differed based on gender and prior performance. Student usage of the videos varied widely and students with lower self‐efficacy were more inclined to use the resources. The provision of the videos did not improve overall cohort performance as compared to a historical cohort, however, those students that accessed all video sets experienced a greater normalized learning gain compared to students that used none or one of the four sets of videos. Student reports and usage patterns indicate that the videos were primarily used for practical class preparation and revision. Potentially, the videos represent a passive mode of teaching whereas active learning has been demonstrated to result in greater learning gains. Adapting the videos into interactive tutorials which will provide opportunity for feedback and the development of students' self‐evaluation may be more appropriate.

Students enrolled in the Optometry program at the University of Manchester are required to take a functional anatomy course during the first year of their studies. Low mean scores in the written examination of this unit for the past two academic years energized staff to rethink the teaching format. Interactive sessions lasting 20 minutes each were introduced during the two hour lecture sessions. In these sessions students reinforced their anatomical knowledge learned in lectures, through playing games such as anatomy bingo and solving anatomical anagrams. In addition, five e‐learning modules were also introduced for students to complete in their own time. A pre‐ and postcourse questionnaire were distributed to obtain student views on their expectations of the course and interactive sessions. Comparisons were made between written examination results from 2008 to 2009 to written examination results from the previous five academic years to see if the interactive sessions and e‐learning modules had any impact on student knowledge. In addition, comparisons were made between student performances on the functional anatomy course with their performance in all of the other assessments taken by the students during their first year of study. Analysis of the questionnaires showed that student's expectations of the course were fulfilled and the interactive sessions were well received by the majority. There was a significant increase (P ≤ 0.01) in the mean examination score in 2008–2009 after introduction of the interactive sessions and e‐learning modules compared with scores in previous years. The introduction of interactive sessions has increased student enjoyment of the module and along with the e‐learning modules have had a positive impact on student examination results.

Dilated canine hearts were used to teach undergraduate students internal and external cardiac anatomy. The specimens were dilated using hydrostatic pressure and then fixed using 5% formalin. These specimens provided the students with an alternative to prepackaged embalmed hearts and anatomical models for studying the external and internal cardiac anatomy. In addition, the dilated hearts are more similar to the organ they encounter within the thoracic cavity of their dissected animal. This gives the students a better chance of developing a three‐dimensional understanding of the heart. Anat Sci Ed 1:207–211, 2008. © 2008 American Association of Anatomists.  相似文献

Reciprocal peer teaching (RPT), wherein students alternate roles as teacher and learner, has been applied in several educational arenas with varying success. Here, we describe the implementation of a reciprocal peer teaching protocol in a human gross anatomy laboratory curriculum. We compared the outcomes of the RPT class with those of previous classes in which RPT was not employed. Objective data (i.e., course grades) show no significant differences in gross anatomy laboratory grades between students in the RPT and non‐RPT classes. To subjectively evaluate the relative success of RPT in the laboratory, we analyzed student opinions obtained through anonymous surveys. These data show that a powerful majority of student respondents felt that RPT was beneficial and should be used in future classes. The greatest disadvantage was unreliable quality of teaching from peers; however, most students still felt that RPT should be continued. Students who felt that they had insufficient hands‐on experience (by virtue of dissecting only half the time) were significantly more likely to recommend abandoning RPT. These results underscore the importance of active student dissection, and suggest that a modified version of the described RPT protocol may satisfy more of the needs of large, diverse student populations. Several hidden benefits of RPT exist for faculty, administration, and students, including reduced need for large numbers of cadavers, attendant reduction in operating costs, and smaller student‐to‐teacher ratios.

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

Innovative educational strategies can provide variety and enhance student learning while addressing complex logistical and financial issues facing modern anatomy education. Observe‐Reflect‐Draw‐Edit‐Repeat (ORDER), a novel cyclical artistic process, has been designed based on cognitivist and constructivist learning theories, and on processes of critical observation, reflection and drawing in anatomy learning. ORDER was initially investigated in the context of a compulsory first year surface anatomy practical (ORDER‐SAP) at a United Kingdom medical school in which a cross‐over trial with pre‐post anatomy knowledge testing was utilized and student perceptions were identified. Despite positive perceptions of ORDER‐SAP, medical student (n = 154) pre‐post knowledge test scores were significantly greater (P < 0.001) with standard anatomy learning methods (3.26, SD = ±2.25) than with ORDER‐SAP (2.17, ±2.30). Based on these findings, ORDER was modified and evaluated in the context of an optional self‐directed gross anatomy online interactive tutorial (ORDER‐IT) for participating first year medical students (n = 55). Student performance was significantly greater (P < 0.001) with ORDER‐IT (2.71 ± 2.17) when compared to a control tutorial (1.31 ± 2.03). Performances of students with visual and artistic preferences when using ORDER were not significantly different (P > 0.05) to those students without these characteristics. These findings will be of value to anatomy instructors seeking to engage students from diverse learning backgrounds in a research‐led, innovative, time and cost‐effective learning method, in the context of contrasting learning environments.

Peer teaching has been recognized as a valuable and effective approach for learning and has been incorporated into medical, dental, and healthcare courses using a variety of approaches. The success of peer teaching is thought to be related to the ability of peer tutors and tutees to communicate more effectively, thereby improving the learning environment. Near‐peer teaching involves more experienced students acting as tutors who are ideally placed to pass on their knowledge and experience. The advantage of using near‐peer teachers is the opportunity for the teacher to reinforce and expand their own learning and develop essential teaching skills. This study describes the design and implementation of a program for fourth year medical students to teach anatomy to first‐ and second‐year medical students and evaluates the perceptions of the near‐peer teachers on the usefulness of the program, particularly in relation to their own learning. Feedback from participants suggests that the program fulfills its aims of providing an effective environment for developing deeper learning in anatomy through teaching. Participants recognize that the program also equips them with more advanced teaching skills that will be required as they move nearer toward taking on supervisory and teaching duties. The program has also provided the school with an additional valuable and appropriate resource for teaching anatomy to first‐ and second‐year students, who themselves view the inclusion of near‐peer teachers as a positive element in their learning.

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.

Hands-on dissection-based learning of anatomy offers an unique and valued experience for medical students. Too often however, the inexperienced student's focus is to avoid damage to unfamiliar structures instead of understanding spatial relationships between structures. This results in unfortunate surrender of a critical learning experience. Additionally, approaches to dissection and anatomic exposure share little alignment to clinical approaches, making it less powerful in clinical applicability. The goal of this viewpoint commentary is based on the experience of the two authors and aims to demonstrate opportunity to introduce clinical approaches for dissection while incorporating relevant anatomical concepts in medical school curriculum that aligns with authentic healthcare practice. Using the dissections of the superficial face as a relevant and current topic of clinical interest, we point out that applying the currently performed dissection approach (medial-to-lateral) falls short of providing sufficient knowledge and understanding of the layered arrangement of facial structures. The lateral-to-medial approach, as performed in surgical face lifting procedures would offer a better understanding of the layers of the face and especially the superficial musculoaponeurotic system (SMAS) accounting for the difficulties of facial dissections on embalmed cadavers. This commentary could offer a potential change in paradigm for students and course facilitators for how to maximize the knowledge transfer during facial dissections. It potentially opens a door to rethink dissection-based learning of anatomy toward techniques and approaches that are aligned to surgical access pathways and thus considered more clinically relevant.  相似文献

Ultrasound (US) can enhance anatomy education, yet is incorporated into few non‐medical anatomy programs. This study is the first to evaluate the impact of US training in gross anatomy for non‐medical students in the United States. All 32 master's students enrolled in gross anatomy with the anatomy‐centered ultrasound (ACUS) curriculum were recruited. Mean Likert ratings on pre‐ and post‐course surveys (100% response rates) were compared to evaluate the effectiveness of the ACUS curriculum in developing US confidence, and gauge its impact on views of US. Post‐course, students reported significantly higher (P < 0.001) mean confidence ratings in five US skills (pre‐course versus post‐course mean): obtaining scans (3.13 ±1.04 versus 4.03 ±0.78), optimizing images (2.78 ±1.07 versus 3.75 ±0.92), recognizing artifacts (2.94 ±0.95 versus 3.97 ±0.69), distinguishing tissue types (2.88 ±0.98 versus 4.09 ±0.69), and identifying structures (2.97 ±0.86 versus 4.03 ±0.59), demonstrating the success of the ACUS curriculum in students with limited prior experience. Views on the value of US to anatomy education and to students' future careers remained positive after the course. End‐of‐semester quiz performance (91% response rate) provided data on educational outcomes. The average score was 79%, with a 90% average on questions about distinguishing tissues/artifacts, demonstrating positive learning outcomes and retention. The anatomy‐centered ultrasound curriculum significantly increased confidence with and knowledge of US among non‐medical anatomy students with limited prior training. Non‐medical students greatly value the contributions that US makes to anatomy education and to their future careers. It is feasible to enhance anatomy education outside of medical training by incorporating US. Anat Sci Educ 10: 348–362. © 2016 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.

Rapid changes in medical knowledge are forcing continuous adaptation of the basic science courses in medical schools. This article discusses a three‐year experience developing a new Computed Tomography (CT)‐based anatomy curriculum at the Sackler School of Medicine, Tel Aviv University, including describing the motivations and reasoning for the new curriculum, the CT‐based learning system itself, practical examples of visual dissections, and student assessments of the new curriculum. At the heart of this new curriculum is the emphasis on studying anatomy by navigating inside the bodies of various living individuals utilizing a CT viewer. To assess the students’ experience with the new CT‐based learning method, an anonymous questionnaire was administered at the end of the course for three consecutive academic years: 2008/2009, 2009/2010, 2010/2011. Based upon the results, modifications were made to the curriculum in the summers of 2009 and 2010. Results showed that: (1) during these three years the number of students extensively using the CT system quadrupled (from 11% to 46%); (2) students' satisfaction from radiologists involvement increased by 150%; and (3) student appreciation of the CT‐based learning method significantly increased (from 13% to 68%). It was concluded that discouraging results (mainly negative feedback from students) during the first years and a priori opposition from the teaching staff should not weaken efforts to develop new teaching methods in the field of anatomy. Incorporating a new curriculum requires time and patience. Student and staff satisfaction, along with utilization of the new system, will increase with the improvement of impeding factors.
