The model of this study was the Solomon four-group model. In the study, the Cooperative Learning Process Scale and the Science Achievement Test were used to collect data. In the light of the findings, the cooperative learning activities done in the experimental group have meaningfully increased the student achievement in comparison to the control group. According to the findings, it was determined that the activities were prepared appropriately to the cooperative learning and that they were organised considering the basic principles of cooperative learning. 85.07 per cent of the students have stated that the activities done were appropriate for high level cooperative learning.en10.7227/RIE.0018info:eu-repo/semantics/closedAccessachievementcooperative learningcooperative learning process scalejigsawstudent team achievement divisionArticle9511932Q2N/A
