โฆ Synopsis
Published papers are available on numerous models for the production of educational software. Teachers have contributed curriculum ideas to many of these. Some Computer Assisted Learning (CAL) development methods include trials of software in schools to provide feedback in the development process. This paper discusses the effectiveness of classroom trials, using an example from the Computers in the Curriculum project. Consideration is given to the relation between this formative development and general research questions concerning the contribution of CAL to learning.
