The design of e-learning environments should take into account principles of learning and principles of usability. To achieve this, e-learning applications should undergo usability evaluation and subsequent refinement. The main objectives of this study are (1) to present a synthesised framework of usability evaluation criteria suitable for evaluating a stand-alone offline e-learning tutorial, and (2) to evaluate the tutorial using the usability testing evaluation method and the criteria in the framework. A further aim is to determine the effectiveness of the framework in conducting this task. The framework consists of twelve criteria, each of which has a number of sub-criteria. The use of the framework and usability testing proved to be effective in evaluating the tutorial. The major problems identified were related to the poor structure and navigability of the interactive tutorial, as well as weaknesses in its Help system. These impact negatively on the use of the tutorial for learning.
