Abstract T he present study aimed at tackle this problem by investigating the effectiveness of using 4MAT model for developing the preparatory stage pupils' creative thinking skills in science.Atest of creative thinking skills in science) was developed. The participants consisted of 89 first-grade preparatory stage pupils who were divided into 49 for the experimental group and 40 for the control group.Two instructional units entitled "Material and its structure as well as energy" included in the first-grade preparatory stage pupils' science book were modified and taught to the experimental group pupils according to 4MAT model. The control group received regular instruction.
