Effect of Ability Grouping in Collaborative Learning and Locus of Control on Individual Achievements

This research focus on effect of ability grouping and locus of control in collaborative learning on individual achievements. Investigated important forms of grouping are used in collaborative learning. Expected to be obtained form the appropriate grouping for collaborative learning. The results research showed that (1) there are differences in individual achievement significantly between high homogeneous group, low homogeneous group, and heterogeneous group in collaborative learning, (2) there are differences in individual achievement significantly between with an internal locus of control and external locus of control, (3) there is no interaction effect between ability grouping in collaborative learning and locus of control on individual achievement. Based on the results of descriptive statistical analysis showed that the individual achievement of high homogeneous group turned out to mean the highest, followed then a heterogeneous group, and the lowest low homogeneous group, the individual achievement who have an internal locus of control is higher than the individual achievement who have an external locus of control.
