CONSPECT: monitoring conceptual development

Wild, Fridolin; Haley, Debra and Bülow, Katja (2010). CONSPECT: monitoring conceptual development. In: 9th International Conference on Web-based Learning (ICWL 2010), 7-11 Dec 2010, Shanghai, China.




This paper describes and evaluates CONSPECT, a service that analyses states in a learner's conceptual development. CONSPECT combines two technologies - Latent Semantic Analysis (LSA) and Network Analysis (NA) into a technique called Meaningful Interaction Analysis (MIA). It uses LSA for the language analysis and NA to provide visualisations of the semantic relatedness information calculated by LSA. CONSPECT was designed to help both learners and tutors monitor conceptual development. This paper reports on the verification activities undertaken to show how well LSA matches humans in clustering similar concepts. The verification used the edit distance between card sorts to quantitatively evaluate the service.
