Evaluation of Neuroanatomy Web Resources for Undergraduate Education: Educators' and Students' Perspectives

A novel 3D surgical neuroanatomy course for medical students: Outcomes from a pilot 6-week elective

BACKGROUND

Developing and maintaining a three-dimensional working knowledge of neuroanatomy is an essential skill in neurosurgery. However, conventional 2D head, neck, and neuroanatomy education is typically characterized by the separate rote learning of constituent tissues and often fails to provide learners with a contextual understanding of the relationships between these highly complex and interconnected structures. This can pose a significant challenge to medical students entering neurosurgery who lack a topographic understanding of intracranial anatomy.

METHODS

We report on the design and efficacy of a novel 6-part 3D surgical neuroanatomy pilot elective for medical students that utilized a navigation-based pedagogical technique with the goal of providing students with a framework for developing a 3D mental map of the skull base, neurovasculature, ventricular system, and associated brain regions. Students took on the perspective of physically traveling along the paths of key structures with a 360-degree view of surrounding anatomy such that they could appreciate the integration and relative spatial relationships of the varying tissues within the cranium. Mental navigation exercises and pre- and post-course surveys were used to assess students' baseline and learned familiarity with the different anatomical regions covered.

RESULTS

At the conclusion of the course, all students were able to successfully complete all of the multifaceted mental navigation exercises. Post-course survey data indicated that respondents perceived significant increases in their knowledge of cranial nerves; anterior, middle, and posterior skull base anatomy; anterior and posterior cranial circulation; and the ventricular system.

CONCLUSION

3D navigation-based fly-through instruction is a novel and effective technique for teaching complex anatomy and can provide learners with the foundational skills for developing and maintaining a 3D mental map of intracranial anatomy.

eNEUROANAT-CF: a Conceptual Instructional Design Framework for Neuroanatomy e-Learning Tools

In an era which is witnessing a significant rise in incidence of neurological diseases, there is also a rise in neurophobia: the diminished confidence of clinical practitioners and students to manage patients with neurological conditions. In this context, the perceived nexus between neuroanatomy-phobia (the challenges and fear associated with learning neuroanatomy) and neurophobia highlighted the need to revisit the neuroanatomy pedagogies and their instructional designs. e-Learning can be effectively employed to enhance students' learning of neuroanatomy. This perspective describes a conceptual framework for online neuroanatomy learning (e-neuroanatomy learning conceptual framework (eNEUROANAT-CF)), which provides a theoretical grounding to newly developed neuroanatomy e-learning resources, by offering a set of instructional design principles. The framework is rooted in the theories of adult learning, cognitive load, and Mayer's theory of multimedia learning. eNEUROANAT-CF was validated by imparting user opinion regarding the best perceived instructional design features for learning neuroanatomy. Furthermore, it was effectively employed to inform the pedagogical construct of an e-tool to help students learn the spinal pathways. The perspective highlights the theoretical underpinnings of the eNEUROANAT-CF under seven categories, namely "avoidance of cognitive overload," "learning style preferences," "contextualization," "motivation," "social learning," "feedback/reflection," and "active learning." In addition, elaborative examples are provided, which explains how eNEUROANAT-CF informed the instructional design features of the abovementioned e-tool. The authors propose that any novel, interactive neuroanatomy e-learning resource rooted in the instructional design principles outlined by the eNEUROANAT-CF will improve users' learning and understanding of neuroanatomy. The research shows promise to help break the perceived nexus between neuroanatomy-phobia and neurophobia.

TEL Methods Used for the Learning of Clinical Neuroanatomy

Ubiquity of information technology is undoubtedly the most substantial change to society in the twentieth and twenty-first centuries and has resulted in a paradigm shift in how business and social interactions are conducted universally. Information dissemination and acquisition is now effortless, and the way we visualise information is constantly evolving. The face of anatomy education has been altered by the advent of such innovation with Technology-Enhanced Learning (TEL) now commonplace in modern curricula.With the constant development of new computing systems, the temptation is to push the boundaries of what can be achieved rather than addressing what should be achieved. As with clinical practice, education in healthcare should be evidence driven. Learning theory has supplied educators with a wealth of information on how to design teaching tools, and this should form the bedrock of technology-enhanced educational platforms. When analysing resources and assessing if they are fit for purpose, the application of pedagogical theory should be explored and the degree to which it has been applied should be considered.

Teaching brain imaging through a drawing method may improve learning in medical students

OBJECTIVES

Brain imaging is particularly difficult to learn and to teach. This study aimed to evaluate the performance of teaching brain imaging through drawing method in medical faculty students.

METHODS

We conducted a prospective, interventional, randomized, single-blind study in third-year voluntary medical students between December 2016 and June 2019. Eighty medical students received a theoretical training on brain imaging interpretation and were subsequently randomized into two groups ("teaching through drawing" and "standard teaching"). An initial evaluation was carried out to assess the students' basic level. Three teaching and training sessions were spread over 2 months in each group. One month after the third teaching session, students were evaluated by an examiner who was blind to the student's group. The same comprehensive evaluation grid has been used for the initial and final students' evaluations to give an objective score out of 20 points. Students' scores were compared between groups using the t test and effect sizes were measured using Cohen's d.

RESULTS

Students' mean age was 21.1 years old. In total, 61.3% were female. Regarding initial evaluation, scores did not differ significantly between both groups (10.1 ± 2.0 versus 9.9 ± 1.9, p = 0.65), thus confirming the homogeneity of the students' basic level. The scores obtained from the final evaluation were significantly higher for the "teaching through drawing" students than for the "standard teaching" students (14.7 ± 2.7 vs 13.2 ± 2.0, p = 0.009, Cohen's d = 0.62).

CONCLUSIONS

This study provides class II evidence that the method of drawing alone can improve brain imaging comprehension and analysis in medical faculty students.

KEY POINTS

• The method of drawing can improve brain imaging analysis in medical faculty students. • A large majority of students were satisfied by the method of brain imaging teaching through drawing.
