An approach to the evaluation of hypermedia

This paper discusses some methods which may be applied to the evaluation of hypermedia, based on the six models described by Lawton[6]: the classical experimental model; the research and developmental model: the illuminative model; the briefing decision-makers model; the teacher as researcher model; and the case-study model. The use of a number of techniques are discussed, including observation, self-report measures, interviews, automated measures and psychometric tests. Criteria are provided for deciding on an approach which is congruent with the objectives of evaluation.
