A series of computer-aided learning (CAL) lessons for first year analytical chemistry was developed by the University of South Africa (UNISA) and made available to students as an optional learning activity. Evaluation of the courseware was performed in the real instructional setting to obtain information on the feasibility and the effectiveness of this approach to tuition for distance education in South Africa. A relatively small percentage (15%) of the students that submitted assignments used the courseware, although considerably more (28%) of the students claimed to have access to suitable computers. Reasons for the low percentage use are mainly due to factors such as financial and time limitations. The learning outcome of the courseware was established by comparing the results which students obtained for an assignment. Although the results of students that did the courseware were significantly better only at the 80% confidence level, the students responded positively and wanted more exposure to CAL. It became clear that students should be able to access the lessons freely to ensure maximum benefit. The implementation of interactive media for education requires an increase of students' levels of computer literacy, as well as the ensurance of equal access to all facets of tuition to all.
