This paper presents an exploratory study about the development of a structural and measurement model
for the technological acceptance (TAM) of a web-based educational tool. The aim consists of measuring
not only the use of this tool, but also the external variables with a significant influence in its use for planning
future improvements. The tool, designed with Shockwavee and Macromedia Directore, is a web-based
educational environment that has been applied as a teaching methodology in an undergraduate course
involved with modern microprocessors architectures and applications. The proposed methodology may
be extensible to similar tools and tries to fill the lack of scientific studies in the validation and acceptance
of computer-based educational tool
