Abstract. The medical curriculum is the main tool representing the entire
undergraduate medical education. Due to its complexity and multilayered structure
it is of limited use to teachers in medical education for quality improvement
purposes. In this study we evaluated three visualizations of curriculum data from a
pilot course, using teachers from an undergraduate medical program and applying
visual analytics methods. We found that visual analytics can be used to positively
impacting analytical reasoning and decision making in medical education through
the realization of variables capable to enhance human perception and cognition on
complex curriculum data. The positive results derived from our evaluation of a
medical curriculum and in a small scale, signify the need to expand this method to
an entire medical curriculum. As our approach sustains low levels of complexity it
opens a new promising direction in medical education informatics research.
Keywords. Visual analytics, medical education, analytical reasoning, decision
making.
Introduction
Undergraduate medical education is a complex system that constantly needs to be
evaluated and transformed to follow the fast pace of changing healthcare. The medical
curriculum, as the main instrument in hands of medical teachers for planning,
designing and delivering learning and assessment activities towards the learning
outcomes is inherently complex and thereby unexploited for analysis and decision
support concerning changes and improvements in medical education [1],[2]. In a
previous study we reported the limited use of curriculum data for such purposes and we
demonstrated how visual analytics (VA) as a new research field can be applied to
analyze and visualize a medical curriculum [3]. We also applied VA at the level of
competencies and learning outcomes of an undergraduate medical program with
possible positive effects on reducing the curriculum’s complexity by creating networks
of information representing the curriculum. Previous studies have used VA in higher
