Based on the results of the study, it was obtained in cycle 1 that the creativity indicator for fluent thinking was 37% in the less category; cycle II 60% in the good category, and cycle III 73% in the good category; then the flexible thinking indicator in cycle I was 36% in the less category, cycle II 65% in the good category, and cycle III 78% in the good category; original thinking indicator cycle I is 20% in the less category, cycle II 61% is in the good category and cycle III 75% in the good category; elaboration thinking indicator cycle I is 15% in the very less category, cycle II 57% in the sufficient category and cycle III 67% in the good category. Learning outcome data in cycle I is only 37% of students who completed, cycle II 60% of students who completed, and cycle III 78% of students who completed.
