Neuroanatomy Learning: Augmented Reality vs. Cross-Sections

Neuroanatomy education is a challenging field which could benefit from modern innovations, such as augmented reality (AR) applications. This study investigates the differences on test scores, cognitive load, and motivation after neuroanatomy learning using AR applications or using cross-sections of the brain. Prior to two practical assignments, a pretest (extended matching questions, double-choice questions and a test on cross-sectional anatomy) and a mental rotation test (MRT) were completed. Sex and MRT scores were used to stratify students over the two groups. The two practical assignments were designed to study (1) general brain anatomy and (2) subcortical structures. Subsequently, participants completed a posttest similar to the pretest and a motivational questionnaire. Finally, a focus group interview was conducted to appraise participants’ perceptions. Medical and biomedical students (n = 31); 19 males (61.3%) and 12 females (38.7%), mean age 19.2 ± 1.7 years participated in this experiment. Students who worked with cross-sections (n = 16) showed significantly more improvement on test scores than students who worked with GreyMapp-AR (P = 0.035) (n = 15). Further analysis showed that this difference was primarily caused by significant improvement on the cross-sectional questions. Students in the cross-section group, moreover, experienced a significantly higher germane (P = 0.009) and extraneous cognitive load (P = 0.016) than students in the GreyMapp-AR group. No significant differences were found in motivational scores. To conclude, this study suggests that AR applications can play a role in future anatomy education as an add-on educational tool, especially in learning three-dimensional relations of anatomical structures.     

Combining fiber dissection,plastination, and tractography for neuroanatomical education: Revealing the cerebellar nuclei and their white matter connections

In recent years, there has been a growing interest in white matter anatomy of the human brain. With advances in brain imaging techniques, the significance of white matter integrity for brain function has been demonstrated in various neurological and psychiatric disorders. As the demand for interpretation of clinical and imaging data on white matter increases, the needs for white matter anatomy education are changing. Because cross‐sectional images and formalin‐fixed brain specimens are often insufficient in visualizing the complexity of three‐dimensional (3D) white matter anatomy, obtaining a comprehensible conception of fiber tract morphology can be difficult. Fiber dissection is a technique that allows isolation of whole fiber pathways, revealing 3D structural and functional relationships of white matter in the human brain. In this study, we describe the use of fiber dissection in combination with plastination to obtain durable and easy to use 3D white matter specimens that do not require special care or conditions. The specimens can be used as a tool in teaching white matter anatomy and structural connectivity. We included four human brains and show a series of white matter specimens of both cerebrum and cerebellum focusing on the cerebellar nuclei and associated white matter tracts, as these are especially difficult to visualize in two‐dimensional specimens and demonstrate preservation of detailed human anatomy. Finally, we describe how the integration of white matter specimens with radiological information of new brain imaging techniques such as diffusion tensor imaging tractography can be used in teaching modern neuroanatomy with emphasis on structural connectivity.

Impact and educational outcomes of a small group self‐directed teaching strategy in a clinical neuroscience curriculum

The complexity of the material being taught in clinical neuroscience within the medical school curriculum requires creative pedagogies to teach medical students effectively. Many clinical teaching strategies have been developed and are well described to address these challenges. However, only a few have been evaluated to determine their impact on the performance of students studying clinical neuroscience. Interactive, 2‐hour, self‐directed small‐group interactive clinical case‐based learning sessions were conducted weekly for 4 weeks to integrate concepts learned in the corresponding didactic lectures. Students in the small groups analyzed cases of patients suffering from neurological disease that were based on eight learning objectives that allowed them to evaluate neuroanatomical data and clinical findings before presenting their case analysis to the larger group. Students’ performances on the formative quizzes and summative tests were compared to those of first‐year medical students in the previous year for whom the self‐directed, small‐group interactive clinical sessions were not available. There was a significant improvement in the summative performance of first‐year medical students with self‐directed clinical case learning in the second year (Y2) of teaching clinical neuroscience (P < 0.05) when compared with first‐year students in the first year (Y1) for whom the self‐directed learning approach was not available. Student performance in the formative assessments between Y1 and Y2 was not significantly different (P = 0.803). A target of ≥70% student scoring above 80% in the final summative examination was met. The current study revealed evidence for the impact and educational outcomes of a self‐directed, clinical teaching strategy in a clinical neuroscience curriculum for first‐year medical students.

Design and development of a new facility for teaching and research in clinical anatomy

This article discusses factors in the design, commissioning, project management, and intellectual property protection of developments within a new clinical anatomy facility in the United Kingdom. The project was aimed at creating cost‐effective facilities that would address widespread concerns over anatomy teaching, and support other activities central to the university mission–namely research and community interaction. The new facilities comprise an engaging learning environment and were designed to support a range of pedagogies appropriate to the needs of healthcare professionals at different stages of their careers. Specific innovations include integrated workstations each comprising of a dissection table, with removable top sections, an overhead operating light, and ceiling‐mounted camera. The tables incorporate waterproof touch‐screen monitors to display images from the camera, an endoscope or a database of images, videos, and tutorials. The screens work independently so that instructors can run different teaching sessions simultaneously and students can progress at different speeds to suit themselves. Further, database access is provided from within an integrated anatomy and pathology museum and display units dedicated to the correlation of cross‐sectional anatomy with medical imaging. A new functional neuroanatomy modeling system, called the BrainTower®, has been developed to aid integration of anatomy with physiology and clinical neurology. Many aspects of the new facility are reproduced within a Mobile Teaching Unit, which can be driven to hospitals, colleges, and schools to provide appropriate work‐based education and community interaction.

Intensive mode delivery of a neuroanatomy unit: Lower final grades but higher student satisfaction

In 2011, Macquarie University moved to a three‐session academic year which included two 13‐week sessions (traditional mode) and one seven‐week session (intensive mode). This study was designed to compare the intensive and traditional modes of delivery in a unit of undergraduate neuroanatomy. The new intensive mode neuroanatomy unit provided the same quantity and quality of material to the same standard, delivered by the same teachers and over the same total hours, but in a shorter timeframe. All students enrolled in session 2 (traditional mode) and session 3 (intensive mode) were invited to participate in this study. The main outcome measures were the final course grades and level of satisfaction with the course. Although there was no significant difference between the two cohorts in self‐rated level of knowledge (P = 0.148), the traditional mode cohort achieved significantly higher final grades compared to the intensive mode cohort (P = 0.001). Similarly, the distribution of final grades was also different between the two cohorts. The two cohorts were equally satisfied with the unit overall, and with the lectures and tutorials. However, the intensive mode cohort was more satisfied with the laboratory practical classes compared to the traditional mode cohort (P < 0.001). Thus this study demonstrates that in the case of neuroanatomy, which is high in content, when the course is taught to the same standards as exist in the traditional mode of delivery, the students do not do as well even though they enjoy the course equally.

Perceptions of junior doctors and undergraduate medical students as anatomy teachers: Investigating distance along the near‐peer teaching spectrum

Near‐peer teaching involves more experienced students acting as tutors and has been widely used in anatomy education. This approach has many advantages for the learner due to the social and cognitive congruence they share with the teacher, however, the influence of distance between the teacher and learner on these congruences has yet to be explored. The aim of this study was to compare the attitudes and perceptions of the student learner towards neuroanatomy review sessions taught by either a senior medical student or a junior doctor. The students were randomly assigned to an allocated tutor. All tutors used standardized material and had access to identical resources. The type of allocated tutor was swapped between the two teaching sessions and 99 student feedback forms were collected in total. The rating for the overall quality of the teaching session was not significantly different between the junior doctors and senior medical students (P = 0.11). However, criteria closely relating to social and cognitive congruence such as “enjoyment of the session,” “delivery of the teaching,” and “was it a good use of time” were all rated significantly higher for the senior medical students (P < 0.05). The results of this study suggest that small increases in distance along the near‐peer teaching spectrum have an impact upon the student's perception of their learning experience. While all teachers were suitable role models it appears that junior doctors are too far removed from their own undergraduate experiences to share congruences with pre‐clinical medical students.

Working in Creative Partnership with Students to Co-Produce Neuroanatomy e-Learning Resources in a New Era of Blended Learning

Anatomists are well placed to tackle the transition from face-to-face to blended learning approaches as a result of the rapidly forced changes brought about by Covid-19. The subject is extremely visual and has, therefore, previously been a target for the development of technology-enhanced learning initiatives over the last ten years. Today's students have come to expect the integration of technology in the classroom and remotely. They adjust quickly to the innovative use of new applications and software and have begun to integrate it within their own workflow for note taking and study aids. Given the intense drive toward blended deliveries of anatomy as a result of the Covid-19 pandemic, it is easy to picture how the benefits of working in partnership with students (in order to achieve many of these aims) would be possible, particularly in difficult subjects like neuroanatomy. In doing so, it provides anatomists with new opportunities to engage students in a way that aligns well with best practice frameworks for engaging students through partnership. The current United Kingdom guidelines set out by Advance HE (a professional membership organization for promoting excellence in higher education) strongly encourages the higher education community to seek out appropriate academic contexts where a balance of power can be struck between staff and student to create a community of practice. If such an approach can be fully embraced by anatomists, a strong argument can be made for seizing the opportunity to optimize the benefits of student partnership work in this discipline.     

Anatomists debate the value of a teaching credential

Fewer and fewer programs are training graduate students and postdoctoral fellows in the classical anatomical disciplines. Nonetheless, there remains a need at all levels of clinical and basic science education for skilled instructors of anatomy, histology, and embryology. Two sessions at the 2006 annual meeting of the American Association of Anatomists (AAA) explored whether a system of accreditation would benefit students, institutions, and training programs. Although the value of accreditation was controversial, three challenges for the various anatomical societies emerged from these discussions: (1) To identify the skills and knowledge that should be shared among all anatomists, and the more specific skills and knowledge needed for the diverse settings in which anatomists work. (2) To address the historical inattention of institutions to the training of educators. (3) To develop strategies to lobby institutions and national organizations to support the training and work of educators in the anatomical sciences. One approach to meeting these challenges would be to develop guidelines for training programs. These guidelines would help graduate students seek the training they need, provide institutions with a benchmark to assess or develop training programs, and provide the basis for focusing lobbying efforts targeted at institutions or existing accreditation bodies.
