Evaluating Usability and Efficaciousness of an E-learning System: A Quantitative, Model-Driven Approach

Using an e-learning system as a case example of complex information systems, we tested a conceptual framework that expands upon the Technology Acceptance Model (TAM) and incorporate measures of self-efficacy. A survey instrument was developed to gather large samples of users´ perceptions on system usability and usefulness. Advanced statistical tests such as structural equation modeling were carried out. The paper concludes with a discussion on efficacy of evaluation techniques and design implications for e-learning systems.
