Multilevel Topic Dependency Models for Assessment Design and Delivery: A Hypergraph Based Approach
Kendra Cooper, Hassan Khosravi · 2019
The effective design and delivery of assessments in a wide variety of evolving educational environments remains a challenging problem.Proposals have included the use of learning dashboards, peer learning environments, and grading support systems; these embrace visualisations to summarise and communicate results.In an on-going project, the investigation of graph based visualisation models for assessment design and delivery has yielded promising results.Here, an alternative graph foundation, a two-weighted hypergraph, is considered to represent assessment results and their explicit mapping to one or more learning objective topics.The visualisation approach considers the hypergraph as a collection of levels; the content of these levels can be customized (i.e., filtered) and presented according to user preferences.A case study on generating hypergraph models using commonly available assessment data and a flexible visualisation approach using historical data from an introductory programming course is presented.
