Navigation system to assist learner to link learning tasks (1 - a measure of dissimilarity between the structure of instructional material and the structure of learner's understanding

摘要

Learners relate the learning tasks by learning. The ability that relate the learning tasks in learning is very important. This paper aims at constructing the navigation system that assists learner to link the learning tasks so that the structure of the learner's understanding will conform to the structure of instructional material. As a primary step, a measure of dissimilarity between two digraphs expressing the structure of instructional material and the structure of learner's understanding respectively is defined. Details about the navigation will be reported at a later date.
