Abstract
This study clarifies the learning effects of online discussions in MBA, especially the learning effects of collective intelligence. For that purpose, we considered from two viewpoints. First, we proposed a speech criterion for collective intelligence and a speech criterion for individual knowledge. Secondly, we examined whether the differences in group members affected collective intelligence. Third, the factors that affect the breadth of the topics covered in group discussions were examined. As a result of classification according to the utterance standard for collective intelligence, it was shown that many students provided horizontal development and provided new viewpoints. In addition, as a result of examining each class year and position, there was a large difference in the number of remarks and the theme of remarks in all categories, and it was highly likely that collective intelligence that differs depending on the classmate's year and position was high. confirmed. It was also confirmed that the factors affecting the breadth of the theme were the number of utterances in the group and the average number of utterances in the thread.
