The purpose of this study was to make a comprehensive conclusion that the cooperative learning is effective or not by meta-analysis. To achieve the purpose of the study, the research questions were set up and the results of the studies were analyzed.
First, what influence does cooperative learning have academic learning achivement? What is the effect of cooperative learning by school level, subject matter, method of grouping, the size of group, the period of applying, the presence of group reward and the model of cooperative learning?
Second, what influence does cooperative learning have on students' affective domain (learning attitude, self-conself, learning interest, social relations and so on? What is the effect of cooperative learning by school level, subject matter, method of grouping, the size of group, the period of applying, the presence of group reward and the model of cooperative learning?
To answer the research questions, the articles, theses and dissertation which were released from 1990 to 2004 were selected. The effect size could be calulated from the 228 theses. The 453 effect sizes were calculated and analyzed. The analysis method was meta-anaylsis which consisted of voting method, traditional statistic method and the average effect size.
The result of analayzing cooperative learning in academic learning achivement showed 23% increase. The average effect size was d=.61(U₃73) which was above average by Cohen's standard. That is, when the average of control group was 50%, the cooperative learning group was 73%.
The results of analyzing the effects of cooperative learning on the academic achievement were as follows; It's most effective in the lower grade of the elementary school. On the whole, the lower, the more effective. By school subjects, the Korean language was the most effective and science was the lowest. Also, in case of the heterogeneous group, 4-5 member group size, the duration over 6 months within one year and no group reward, cooperative learning was more effective. The model of LT(Learning Together) was the most effective. However, it is necessary to be careful in interpreting because of few models.
The results of analyzing the effects of cooperative learning on the affective domain were as follows; The lower grade of elementary school was the highest, while the high school was the lowest. The results were similar to those of the effects of academic achievement. By school subjects, science was the least effective. In case of the heterogeneous group, 10-12 member group size, the duration less than 2 weeks, and no group reward, cooperative learning was more effective. The model of JigsawII was the most effective.
