Pedagogical Perspectives on the Use of Technology within Medical Curricula: Moving Away from Norm Driven Implementation

Technological resources for teaching and learning about human anatomy in the medical course: Systematic review of literature

The consolidation of technology as an alternative strategy to cadaveric dissection for teaching anatomy in medical courses was accelerated by the recent Covid-19 pandemic, which caused the need for social distance policies and the closure of laboratories and classrooms. Consequently, new technologies were created, and those already been developed started to be better explored. However, information about many of these instruments and resources is not available to anatomy teachers. This systematic review presents the technological means for teaching and learning about human anatomy developed and applied in medical courses in the last ten years, besides the infrastructure necessary to use them. Studies in English, Portuguese, and Spanish were searched in MEDLINE, Scopus, ERIC, LILACS, and SciELO databases, initially resulting in a total of 875 identified articles, from which 102 were included in the analysis. They were classified according to the type of technology used: three-dimensional (3D) printing (n = 22), extended reality (n = 49), digital tools (n = 23), and other technological resources (n = 8). It was made a detailed description of technologies, including the stage of the medical curriculum in which it was applied, the infrastructure utilized, and which contents were covered. The analysis shows that between all technologies, those related to the internet and 3D printing are the most applicable, both in student learning and the financial cost necessary for its structural implementation.

Multimodal Three-Dimensional Visualization Enhances Novice Learner Interpretation of Basic Cross-Sectional Anatomy

While integrated delivery of anatomy and radiology can support undergraduate anatomical education, the interpretation of complex three-dimensional spatial relationships in cross-sectional and radiological images is likely to be demanding for novices. Due to the value of technology-enhanced and multimodal strategies, it was hypothesized that simultaneous digital and physical learning could enhance student understanding of cross-sectional anatomy. A novel learning approach introduced at a United Kingdom university medical school combined visualization table-based thoracic cross-sections and digital models with a three-dimensional printed heart. A mixed-method experimental and survey approach investigated student perceptions of challenging anatomical areas and compared the multimodal intervention to a two-dimensional cross-section control. Analysis of seven-point Likert-type responses of new medical students (n = 319) found that clinical imaging (mean 5.64 SD ± 1.20) was significantly more challenging (P < 0.001) than surface anatomy (4.19 ± 1.31) and gross anatomy (4.92 ± 1.22). Pre-post testing of students who used the intervention during their first anatomy class at medical school (n = 229), identified significant increases (P < 0.001) in thoracic cross-sectional anatomy interpretation performance (mean 31.4% ± 15.3) when compared to the subsequent abdominal control activity (24.1% ± 17.6). Student test scores were independent of mental-rotation ability. As depicted on a seven-point Likert-type scale, the intervention may have contributed to students considering cross-sectional interpretation of thoracic images (4.2 ± 1.23) as significantly less challenging (P < 0.001) than comparable abdominal images (5.59 ± 1.14). These findings could have implications for how multimodal cross-sectional anatomy learning approaches are implemented within medical curricula.

The Hidden Curriculum of Utilisation of Imaging and Unregulated Digital Resources within Clinical Education

Clinical education has changed dramatically over the last 30 years. The increasing use of imaging and visualisation technologies within medical, dental and other healthcare sciences education curricula is taken for granted, with little consideration given to the agenda behind the colonisation of the basic sciences curricula with these technologies or their ultimate utility with regards to patient care. Sufficient critique is rarely given prior to the incorporation of imaging modalities into teaching and learning, and the hidden curriculum remains deeply buried under the impetus to 'move with the times'. Coupled with increasingly easily accessible but unregulated streamed digital teaching resources widely utilised in healthcare professions' curricula, there remains a danger that future generations of clinicians may be exposed to erroneous information that could ultimately impact on the safety of their patients. Educators must develop a reflective approach, and together with institutions develop a collective responsibility to integrate and map evidence-based and clinically-relevant approaches within the respective curricula, rather than bombard undergraduates with the latest technology and never-ending (and sometimes unreliable and unregulated) information without awareness of the potential dangers lurking within their preferred teaching methods and ideologies. Healthcare professionals must subject teaching resources utilised within their curricula to the same scrutiny that textbooks undergo, with content accuracy and endorsement via reputable sources, preferably peer reviewed and traceable, taking precedence.
