A Note Taking Evaluation Index Using Term Networks in a Blended Learning Environment

To assess the transformation of a lecturer´s term-based concepts presented to students, both the lecturer´s presentation and the student´s notes in a blended learning course were lexically analyzed and represented in graphs. The contents of these notes were mathematically compared and evaluated. Graphs were then created using the noun co-occurrences in the notes, and the differences in distances between the graph of the lecturer´s presentation and the graph of the student´s notes were calculated. In the results, students recorded additional nouns to replace the nouns given by the lecturer, and introduced new nouns of their own as substitutes as well. Also, the terms students wrote in their notes were not recorded separately, but were linked with other terms.
