A non-parametric test and Cohen’s Kappa test were used to examine differences improvement of student’s creative thinking skills with the IBM Statistics SPSS 20.00 program at .05 significant levels. As a result of the research, it was found that CBL implemented in STEM education has a higher improvement for students of creative thinking skills than CBL combined with worksheet PSL. CBL implemented in STEM education also has a major impact on improvement of students’ creative thinking skills.
