Abstrak

The study addresses the low creative thinking ability in mathematics among students, as observed in grade VIII of MTsN 1 Kota Pariaman. The research gap lies in the need for innovative learning models to enhance creative problem-solving skills. This study aims to determine the effect of the problem posing model on students' creative thinking ability in mathematical problem-solving. Methods: A pre-experimental design with a one-group pretest-posttest was employed. The sample consisted of 32 students selected via purposive sampling. Data were collected through essay tests measuring creative thinking indicators (fluency, flexibility, originality) and analyzed using t-tests. Results: The posttest average (59.64) significantly exceeded the pretest average (23.2), with t count(6.23)>t table(2.018)with. At a significance level of 0.05 and a 95% confidence level, the null hypothesis (H0) was rejected and the alternative hypothesis (Hi) accepted, indicating a significant effect of the problem posing model on the creative thinking ability in mathematical problem solving among eighth-grade students at MTsN 1 Kota Pariaman.
