Study on Supporting Group Discussions by Improving Discussion Skills with Ex Post Evaluation

Problem solving abilities and the development of student interest in learning such activities is important in education, and group discussions are being introduced to classes as a means of achieving such effects. Various computerized group discussion support systems have been developed to support these classes. However, simply supporting the discussion in order to enhance student's ability to meaningfully participate in group discussions is no sufficient. The present paper focuses on the "evaluation" of the discussion so that the teacher can offer appropriate feedback to the students, which is also an important approach for improving skills necessary in discussions.
