Collaborative problem-solving in science instruction allows learners to build their knowledge and understanding through interaction, using the language of science. Computer-mediated communication (CMC) tools facilitate collaboration and may provide the opportunity for interaction when using the language of science in learning. There seems to be…

This article deals with evaluating an interactive learning environment (ILE) during the iterative-design process. Various aspects of the system must be assessed and a number of evaluation methods are available. In designing the ILE Ambre-add, several techniques were combined to test and refine the system. In particular, we point out the merits of…
