In this study, authors aimed at revealing the influence of group size and participant’s personality from the viewpoint of easiness of proposing his/her opinion and also revealing the difference between an onsite situation and an online situation where a discussion is conducted. The authors conducted a questionnaire survey for 76 university students. As a result of the analysis, the following were found: 1) Students feel more difficult to propose their opinion as group size is increased basically under both situations. 2) Under the onsite condition, any participant will feel easy to propose his/her opinion when group size is three or four, while agreeableness and conscientiousness will affect participant’s feelings of difficulty to propose his/her opinion if group size is larger than five. 3) on the other hand, under online condition, agreeableness and neuroticism will affect participant’s feelings of difficulty to propose his/her opinion in any group size.
