 note = {The present study aimed at analyzing the performance and attitude of subjects in small group problem-solving situation, which was established in a class of elementary school. Every problem-solving group was administered two experimental operations, one of which was concerned with the grouping method in terms of subject's intelligence score. In the homogeneous group (Ho) variety of members' IQ was held as minimal as possible. Instead, heterogeneous group (He) was composed of subjects of various IQs whose mean value was of the same across groups. The other operation was related to the strategy of making a solution in a problem-solving group. In the Individual-Group strategy (IGs), each group member put down his own answer at first and then tried to find a group solution through discussion. In the Group strategy (Gs), however, members were given only a discussion session to arrive at a group solution. Two hypotheses tested were : (1) Comparing with the subjects in the Gs condition, subjects in the IGs condition will make more relevant interaction and show better performance and attitude in their group activity. (2) Subjects in the He condition will make more relevant interaction than those in the Ho condition. Furthermore, the formers were expected to show better performance and attitude than the latters. Subjects were elementary school children of 5th grade. Each group was composed of six children. Problem-solving task was a mathematical scale of notation-e. g., transformation task from the binary scale to the decimal scale. The indices of the performance of subjects in a group problem-solving were scores of the various tests (pre-test, post-test and retention-test) which were administered accordiug to the experimental schedule. Furthermore, the attitudinal aspect with special reference to the participation in the group activity was estimated by means of questionnaire. Tape recorders were used to analyze the quality and quantity of the social interactions among group members. Moreover, the interaction processes appeared in a group problem-solving were evaluated by an observer, a graduate studnt majoring in psychology Major results obtained were as follows : (1) The first hypothesis was confirmed, except that there were no significant differences between the indices of member's performance in the Gs and in the IGs conditions. (2) The second hypothesis was also confirmed. Comparing with the effect of grouping method on the performance and attitude, problem-solving strategies didn't have a so profound effect. However, they were found quite effective, especially for less intelligent group members., 国立情報学研究所で電子化したコンテンツを使用している。},
