Evaluation of an ITS for the Passive Voice of the English Language Using the CIAO! Framework

摘要

The CIAO! framework for evaluating educational software has provided insight for several aspects of the software that needed evaluation at several stages; e.g. before any student had interacted with the software and after. In this way, both learning effects and usability issues could be evaluated. The results of the evaluation showed that the Passive Voice Tutor was quite satisfactory but there is scope for improvement in terms of the explanations provided by the system.
