From black-box learning objects to glass-box learning objects

Abstract

In the field of e-learning, a popular solution to make teaching material reusable is to represent it as learning object (LO). However, building better adaptive educational software also takes an explicit model of the learner's cognitive process related to LOs. This paper presents a three layers model that explicitly connect the description of learners' cognitive processes to LOs. The first layer describes the knowledge from a logical perspective. The second describes cognitive processes. The third builds LOs upon the two first layers. The proposed model has been successfully implemented in an intelligent tutoring system for teaching Boolean reduction that provides highly tailored instruction thanks to the model. © Springer-Verlag Berlin Heidelberg 2006.
