Abstract

In this chapter we describe the evaluation of Web-based open and distance learning programs in a more technical manner. First of all we discuss some general theoretical issues that are of importance regarding Web-based ODL environments, such as the communication channel between the participating entities, the issue of learnability and the overall evaluation of such an environment. Then we introduce the principles of educational evaluation, of interface evaluation in general and of expert-based approaches in particular, and we compare the empirical and expert-based methodologies. Finally we present the heuristic evaluation, in its initial form as well as in its Web-adapted variation. The main objectives of the chapter are to prove the applicability of the method in the Web in general and in ODL environments in particular and to investigate the appropriate heuristic list, which can assess the usability and the learnability of such an environment.
