The use of topic maps and concept maps has long been encouraged by instructional designers as a means of providing an overview of content in study materials. Educational theory and practice affirm the effectiveness of concept mapping: as a concise summary of a body of knowledge; as a practical means by which students can construct and record their own knowledge; and as a means of evaluating student understanding. This paper presents the aims, methodology and initial findings of a project commenced in Semester 1 2008, to include hyperlinked concept maps as an enhancement to electronic study materials. The project aims to evaluate their effectiveness: in improving student understanding of the concepts in the course; and as a means of navigating and accessing electronic study materials. The course of study is in the field of Microcomputer Design
