Explaining Human Cognition through Deep Learning

Submitted Apr 15, 2018

Revised Bloom’s Taxonomy is very well known and widely used taxonomy for classifying educational objectives. The said taxonomy describes a hierarchical ordering of cognitive skills from simple to complex. The Revised Taxonomy relaxed the strict cumulative hierarchical assumptions of the Original Taxonomy allowing overlaps. We use a knowledge tracing model, Deep Knowledge Tracing (DKT), to investigate the hierarchical nature of the Revised Taxonomy and also study the overlapping behaviour of the Taxonomy. The DKT model is trained on about 42 million problems attempted on funtoot by the students. We propose a novel way to interpret model output to measure the effects of each learning objectives on every other learning objectives. The results confirms the relaxed hierarchy of the skills from simple to complex. Moreover, results also suggest overlaps even between the non-adjacent skills.

This work is accepted (and will be published) in the top tier conference, Internation Conference of Artificial Intelligence in Education, 2018 (AIED-2018) as a full paper.
