Development of the TUP model - evaluating educational software

Usability evaluation is a crucial step in the iterative software development life-cycle, leading into successful usage of systems. However, most of the usability evaluation methods and tools do not consider all aspects of educational environments. These lacks materialize as unusable results that lead to failures in educational software. Often these results are not comparable and credible, or easily accessible to educators selecting the proper systems for use in their settings; the technology, usability, pedagogy (TUP) evaluation model equally concentrates on the technological, usability, and instructional aspects of educational environments, leading to complete evaluations. In this paper we present the TUP model with the use scenario included and our current WWW prototype of evaluation system based upon it.
