A guidance metric for developing hypermedia educational designs

This paper reports our work in developing the guidance metric to evaluate a hypermedia design for computer-assisted learning (CAL). The metric is based on an integration of two different aspects of an educational hypermedia system. The first aspect is on the structural part which is related to the links between different hypermedia documents in a CAL package. The second aspect is how the organization of different types of educational hypermedia documents affects the performance of a CAL package. An Internet courseware "Interactive Physics Laboratory" (IPL) has been developed to verify the effectiveness of the metric. The results of our preliminary experiments have shown that the metric is suitable and can be useful in developing educational hypermedia systems.
