The Relationship between Technology Acceptance Model and Usability Test - Case of Performing E-learning Task with PDA

In the past, most studies used technology acceptance model (TAM) to test the degree of technology acceptance and usability test to measure the task performance respectively. However, the relationship between TAM and usability has not been addressed. In this paper, an e-learning task was tested and validated with PDA. The findings show that TAM seems more suitable for general purpose context and usability test seems more reasonable and consistency for task-based context.
