An integrated teaching method of gross anatomy and computed tomography radiology

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.

Using structured study questions as a teaching method in social work education: Initial validation studies

The use of study questions to guide student learning and in-class discussion is presented as an alternative to the traditional methods of instruction in social work which rely upon formal lectures, and mid-term and final examinations and term papers to motivate studying. The positive results of two separate investigations on the value of study questions is described, and the instructional technique is suggested as worthy of consideration by social work educators.Bruce A. Thyer, Ph.D., is an Associate Professor of Social Work with the University of Georgia, and an Associate Clinical Professor with the Department of Psychiatry and Health Behavior at the Medical College of Georgia. Dr. Thyer's research interests involve applied behavior analysis within social work practice.Richard Sutphen, M.S.W., received his masters degree from the University of Georgia in 1989.

An interactive method for teaching anatomy of the human eye for medical students in ophthalmology clinical rotations

Much research has shown the benefits of additional anatomical learning and dissection beyond the first year of medical school human gross anatomy, all the way through postgraduate medical training. We have developed an interactive method for teaching eye and orbit anatomy to medical students in their ophthalmology rotation at Duke University School of Medicine. We provide review lectures on the detailed anatomy of the adult human eye and orbit as well as the developmental anatomy of the eye. These lectures are followed by a demonstration of the anatomy of the orbit using conventional frontal and superior exposures on a prosected human cadaver. The anatomy is projected onto a large LCD screen using a mounted overhead camera. Following a brief lecture on clinically relevant anatomy, each student then dissects a fresh porcine (pig) eye under low magnification using a dissecting microscope. These dissections serve to identify structures extrinsic to the eyeball, including extraocular muscle attachments, small vessels, optic nerve stalk, and fascial sheath of the eyeball (Tenon's fascia). Dissection then shifts to the internal anatomy of the eyeball. The size and anatomy of the porcine eye is comparable with that of the human and the dissection provides students with a valuable hands‐on learning opportunity that is otherwise not available in embalmed human cadavers. Students and clinical faculty feedback reveal high levels of satisfaction with the presentation of anatomy and its scheduling early during the ophthalmology clerkship.

The balanced equation to training chemistry ITAs

In an effort to meet the challenge of preparing new international graduate students in chemistry for assignments as teaching assistants (TAs), an innovative training program was designed which incorporated the collaborative efforts of language, pedagogy, and subject matter specialists. This paper describes the approach taken in providing discipline-specific training for new international TAs (ITAs) by providing the rationale and curriculum for such a program and describing the implementation of this program through the academic year. The paper concludes by describing the results of the project on those ITAs who participated and the benefits and limitations of using this approach.Mark W. Tanner obtained his Ph.D. (1991) in Educational Linguistics at the University of Pennsylvania. He is currently, Coordinator of the International Teaching Assistant Program at the University of Washington. Sara Selfe obtained her Ph.D. (1984) in Organic Chemistry at the University of Washington. She is currently Senior Lecturer in the Chemistry Department at the University of Washington and is working to improve the opportunities for Native Americans in the sciences.

Modernization of an anatomy class: From conceptualization to implementation. A case for integrated multimodal–multidisciplinary teaching

It has become increasingly apparent that no single method for teaching anatomy is able to provide supremacy over another. In an effort to consolidate and enhance learning, a modernized anatomy curriculum was devised by attempting to take advantage of and maximize the benefits from different teaching methods. Both the more traditional approaches to anatomy teaching, as well as modern, innovative educational programs were embraced in a multimodal system implemented over a decade. In this effort, traditional teaching with lectures and dissection was supplemented with models, imaging, computer‐assisted learning, problem‐based learning through clinical cases, surface anatomy, clinical correlation lectures, peer teaching and team‐based learning. Here, we review current thinking in medical education and present our transition from a passive, didactic, highly detailed anatomy course of the past, to a more interactive, as well as functionally and clinically relevant anatomy curriculum over the course of a decade.

Equivalence of students' scores on timed and untimed anatomy practical examinations

Untimed examinations are popular with students because there is a perception that first impressions may be incorrect, and that difficult questions require more time for reflection. In this report, we tested the hypothesis that timed anatomy practical examinations are inherently more difficult than untimed examinations. Students in the Doctor of Physical Therapy program at Thomas Jefferson University were assessed on their understanding of anatomic relationships using multiple‐choice questions. For the class of 2012 (n = 46), students were allowed to circulate freely among 40 testing stations during the 40‐minute testing session. For the class of 2013 (n = 46), students were required to move sequentially through the 40 testing stations (one minute per item). Students in both years were given three practical examinations covering the back/upper limb, lower limb, and trunk. An identical set of questions was used for both groups of students (untimed and timed examinations). Our results indicate that there is no significant difference between student performance on untimed and timed examinations (final percent scores of 87.3 and 88.9, respectively). This result also held true for students in the top and bottom 20th percentiles of the class. Moreover, time limits did not lead to errors on even the most difficult, higher‐order questions (i.e., items with P‐values < 0.70). Thus, limiting time at testing stations during an anatomy practical examination does not adversely affect student performance.

The effect of image quality,repeated study,and assessment method on anatomy learning

The use of two‐dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low‐quality and high‐quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low‐quality or high‐quality images, and then completed a comprehension test using either 2D images or three‐dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high‐quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high‐quality vs. low‐quality for hand anatomy P = 0.018; high‐quality vs. low‐quality for eye anatomy P = 0.247). Also, the benefit of high‐quality images on hand anatomy learning was restricted to performance on short‐answer (SA) questions immediately after learning (high‐quality vs. low‐quality on SA questions P = 0.018), but did not apply to performance on multiple‐choice (MC) questions (high‐quality vs. low‐quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

Assessing the impact of the Graduate Certificate in Anatomical Sciences Instruction: A post‐degree survey

There are few graduate programs available for pursuing a doctorate in anatomy where students gain specific training in gross anatomy dissection and the responsibilities of a medical educator. In light of this fact, the University of Kentucky created a Graduate Certificate in Anatomical Sciences Instruction in 2006. This 12‐credit hour curriculum includes detailed training in gross anatomy and/or neuroscience courses, practicum experiences, a seminar class in pedagogical literature, and a course in educational strategies for the anatomical sciences. The award of certificate completion affirms that the candidate has demonstrated faculty‐supervised proficiency in anatomy dissection, instruction in anatomy topics, and teaching strategies for anatomy. Seventeen graduate students have earned the certificate since its inception; nine students accepted teaching positions in anatomy following their graduate training and currently nine certificate graduates have assistant (six) or associate (three) professor positions in academia. In 2016, an anonymous survey including Likert‐style and open‐ended questions was emailed to all certificate graduates. Graduates favorably responded (each question averaged 4.4 or greater out of 5) that the certificate increased their awareness of teaching‐faculty responsibilities, adequately prepared them for teaching‐related duties, and positively contributed toward their first employment. Graduates indicated that the lecturing and dissection experience, awareness of faculty responsibilities, and job preparation (e.g., teaching philosophy development) were the most helpful aspects of the certificate. These results indicate that the Graduate Certificate in Anatomical Sciences Instruction is viewed by its graduates and their employers as a valuable teaching credential that can be attained alongside a basic science degree.

The Panopticon of Childhood: Harold E. Jones Child Study Center,Berkeley, California, 1946–1960

In 1946 the well‐known Danish educator Sofie Rifbjerg (1886–1991) travelled for six months to the USA. The purpose of her trip was to study American developmental psychology. On her way she spent some time at the Institute of Child Welfare at the University of California, Berkeley. The institute had become famous because of its working on longitudinal studies of parents and children during the years of the great Depression. Affiliated with the institute was an experimental kindergarten, where the staff could study and test the development of the pre‐scholars. Until 1960 the Institute as well as the child study centre was housed in a former middle‐class home. In 1957–1960 a new structure was built, designed by the Bay‐area architect Joseph Esherick (1914–1998). Based on material found in the University of California archives the paper describes the story of the building design process, and how the needs of the children clashed with the needs of the scientists with the architect as an aesthetic mediator.     

Take away body parts! An investigation into the use of 3D‐printed anatomical models in undergraduate anatomy education

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.

Anatomical Sciences Education Vol. 7, Issue 1, 2014 Cover Image

ON THE COVER: In response to a Letter to the Editors from Drs. Cornwall and Stringer in New Zealand regarding cadaver CT scans in gross anatomy courses, the ASE Editors received additional letters from schools in the United States and abroad commenting on this practice. One of the letters was from Chika R. Nwachukwu, Ph.D., a current fourth‐year medical student at Mayo Medical School. Chika, who had taken a human anatomy course during her first year in medical school and served as an anatomy teaching assistant during her third‐year, commented that having a CT of their cadaver significantly enhanced her learning. The Mayo course, featured on the cover, utilizes cadaver CTs as an integral part of the anatomy curriculum. These Letters to the Editors are published in the current issue of ASE.     

Evaluation of the effectiveness of 3D vascular stereoscopic models in anatomy instruction for first year medical students

The head and neck region is one of the most complex areas featured in the medical gross anatomy curriculum. The effectiveness of using three‐dimensional (3D) models to teach anatomy is a topic of much discussion in medical education research. However, the use of 3D stereoscopic models of the head and neck circulation in anatomy education has not been previously studied in detail. This study investigated whether 3D stereoscopic models created from computed tomographic angiography (CTA) data were efficacious teaching tools for the head and neck vascular anatomy. The test subjects were first year medical students at the University of Mississippi Medical Center. The assessment tools included: anatomy knowledge tests (prelearning session knowledge test and postlearning session knowledge test), mental rotation tests (spatial ability; presession MRT and postsession MRT), and a satisfaction survey. Results were analyzed using a Wilcoxon rank‐sum test and linear regression analysis. A total of 39 first year medical students participated in the study. The results indicated that all students who were exposed to the stereoscopic 3D vascular models in 3D learning sessions increased their ability to correctly identify the head and neck vascular anatomy. Most importantly, for students with low‐spatial ability, 3D learning sessions improved postsession knowledge scores to a level comparable to that demonstrated by students with high‐spatial ability indicating that the use of 3D stereoscopic models may be particularly valuable to these students with low‐spatial ability.

Assessing Assessment: The Effects of Two Exam Formats on Course Achievement and Evaluation

This research examines the effect of two testing strategies on academic achievement and summative evaluations in an introductory statistics course. In 2001, 63 students underwent an hourly midterm format; and in 2002, 68 students underwent a bi-weekly exam format. Other than the exam format, the class lectures and labs were identical in terms of content, structure, pace, and the cumulative final exam. Findings from the regression analyses show that students in the bi-weekly format performed better than the students in the hourly midterm format. On average, students who took the bi-weekly exams performed about 10 percentage points higher (one letter grade) on the exams during the semester and about 15 percentage points higher on the cumulative final exam compared to their peers who took hourly midterms. The benefits of the bi-weekly format were significantly greater among female students than male students. Finally, students in the bi-weekly format were less likely to drop the class and evaluated the class far more favorably. Carrie B.

Performance and perceptions of distance learners in cyberspace

Abstract

This study compared the performance and perception of cyber‐learners to that of traditional learners. A study of several hundred undergraduate students taking an introductory economics course at the University of California suggests that cyberlearners learn as well as, or better than, traditional learners regardless of characteristics such as gender, ethnicity, academic background, computer skills, and academic aptitude and that they do so with a high degree of satisfaction. CD‐ROM‐based lectures, electronic testing, threaded electronic bulletin boards, and online discussion rooms all appear to be effective instructional technologies. The CD‐ROM‐based lectures that simulated the traditional classroom experience were regarded as being both the most essential and most enjoyable instructional medium.     

Team-based learning in anatomy: an efficient, effective, and economical strategy

Team-based learning (TBL) strategy is being adopted in medical education to implement interactive small group learning. We have modified classical TBL to fit our curricular needs and approach. Anatomy lectures were replaced with TBL that required preparation of assigned content specific discussion topics (in the text referred as "discussion topics"), an individual self-assessment quiz (IRAT), analysis of the discussion topics, and then the team retaking the same quiz (GRAT) for discussion and deeper learning. Embryology and clinical correlations were given as lectures. Unit examinations consisted of graded IRAT and GRAT. The National Board of Medical Examiners (NBME) Subject Examination was the comprehensive final examination. To evaluate the effect of TBL on student performance we compared the departmental and NBME subject examination scores between the traditional and TBL curricula. We collected five years of data on student performance in TBL-based anatomy and lecture-based preclinical courses. Our results show that departmental and NBME subject examination scores for TBL-based anatomy were higher than those for lecture-based anatomy. We subsequently compared average NBME scores for anatomy with those in other preclinical courses that were lecture-based. Average NBME anatomy scores were significantly higher than those for all the lecture-based preclinical courses. Since the introduction of TBL in anatomy, student performance has progressively improved in the NBME subject examination. Students perceived TBL as a motivator to be a responsible team member and to contribute to collective learning by the team. Further, it reinforced self-directed learning and fostered an appreciation for peer respect. Interestingly, these perceptions were uniform irrespective of student course performance.     

Modified use of team‐based learning for effective delivery of medical gross anatomy and embryology

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

Faculty/Staff Perceptions of a Standards-Based Exit Portfolio System for Graduate Students

New standards for certification were recently developed for speech–language pathology graduate training programs by the American Speech-Language-Hearing Association. The new standards are outcomes-based rather than process-based.

Interprofessional education in gross anatomy: Experience with first‐year medical and physical therapy students at Mayo Clinic

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.

ON THE COVER: Students at Monash University in the Centre for Human Anatomy Education . In this issue of ASE, Professor Paul McMenamin and co‐authors describe how they have developed novel methods to produce 3D printed copies of anatomical specimens with data derived from either laser scanning or CT imaging. These 3D prints are being used here in a class of medical students learning head and neck anatomy. The authors hope these 3D prints will act not only to supplement cadaver based instruction but moreover, they point out in their article the potential value of 3D prints for institutions and countries where access to cadaver material is difficult for cultural, ethical or logistic reasons.
