Abstract:

The main difficulties in designing collaborative-learning applications are understanding which interactions between learners and teachers are the appropriate ones and then building software that takes such dynamics into account. Some researchers address this challenge by defining reusable components for specific learning tasks. The problems are that developers impose their particular solution, adapting components to requirement changes requires much effort, developers might lack the expertise to identify the appropriate group dynamics, and the resulting software might be used in unexpected ways. An approach based on an interaction model lets designers and educational experts specify the interactions in a learning activity. They can then define a set of reusable interaction components. The resulting flexible model is the basis for a flexible architecture that lets you create, extend, reuse, and compose diverse educational software products.
