Lifelong learning requires the consistent and continued development of one’s
knowledge, skills, and competencies. However, due to the extensive choice of courses
offered at today’s institutions of higher learning, students face a risk of choice
overload in their selection of (elective) courses. As current findings in choice
overload literature do not refer to student samples in educational settings nor do they
consider the use of interactive visualization formats, the use of interactive
visualization in higher education organizations seems a promising way to support course
selection that fits educational needs. All the more as previous visualization approaches
to overcome table-based visualizations or online course catalogues primarily aim at
communicating curricular content and structure to different university stakeholders,
while disregarding students. We thus introduce our work-in-progress on an interactive
visualization tool called the Course Glancer. The Course Glancer supports students’
decision-making ability when confronted with a variety of learning offers while taking
electives of a bachelor’s degree program in business administration. The tool provides
support for gaining an overview on all available courses and their categories, and for
rapidly comparing course alternatives. In doing so, it can help to clarify course
preferences and finally to foster students’ confidence of not having overlooked an
important course option. This is in line with Shneiderman’s information-seeking mantra
as a must-have for effective cognitive processing: Overview first, zoom and filter, then
details-on-demand. We use this mantra in connection with Norman’s usability principles
of discoverability, affordances, feedback, constraints, mapping, and consistency. An
example of how we use constraints is that course comparison is limited to juxtaposing
two courses only. This functionality considers latest evidence from using eye-tracking
studies that revealed that human beings tend to distribute their attention in an
unbalanced manner and focus mainly on the two options that seem the most promising
alternatives. To enrich the empirical research on choice overload, we plan to focus on
psychological effects in the use of the Course Glancer. These include subjective,
moderating factors (e.g., decision style) and behavior-related measures. The latter
refer to subjective states (choice satisfaction, decision regret, decision confidence)
or behavioral outcomes (e.g., choice deferral, option selection). Beyond these,
group-related effects should also be analyzed in future research, for example, if
interacting with our tool can stimulate information exchange processes within expert
groups of higher education organizations (e.g., in the context of accreditation
procedures or curriculum planning).
