Structured group interaction system for collaborative problem solving

These days we come across many wicked problems whose solutions are beyond individuals intellectual ability. These problems can be resolved through collaborative group interaction. We developed an internet-based asynchronous group interaction support system, after looking into the collaborative problem solving process and the IBIS (Issue-Based Information System) argumentation model. It has the following characteristics: 1) it is developed based on the modified IBIS model which is a model for group interaction to resolve wicked problems; 2) it supports both processes of seeking and comparing solutions, while most similar systems do not have a feature to support the latter process; 3) different structures can be defined dynamically according to the purpose of group interaction, so that it could be used for collaborative problem solving in a specific domain. To show the usability of the system, we carried out an experiment, whose result is shown at the end.
