Abstract: | Teachers remark that during Cooperative Learning (CL), the academic nature of the group discussions and the resulting group products can be disappointing. Often, this may be due to a lack of understanding on the students’ part on the elements that make up an exemplary product. This study examined whether clearly articulated evaluation criteria (EC's) would alter the nature of the group's discussion and subsequently improve students’ learning. The groups using the EC spent more time evaluating their products, discussing the content of their unit and task than students not using the evaluation criteria. The evaluative and task‐focused talk at the group level were modestly, yet significantly correlated with individual scores on an essay test following the unit. These findings suggest that the presence of clear and accessible criteria for evaluation can improve the academic nature of group discussions and individual learning gains. The findings provide a practical way to apply current assessment practices to classrooms using CL strategies. |
