This study aims to describe: (1) The effect of a Realistic Mathematics Education Approach with a Jigsaw Type Cooperative Learning Model on Students' Creative Thinking Abilities; (2) The effect of a Realistic Mathematics Education Approach with a Jigsaw Type Cooperative Learning Model on Students' Learning Independence; (3) The effect of a Realistic Mathematics Education Approach with a Jigsaw Type Cooperative Learning Model on Students' Creative Thinking Abilities and Self-regulated Learning. This research is a quasi-experimental study with a pretest and posttest design. The population in this study were all class VIII students of SMP Negeri 1 Kota Bima for the 2023/2024 academic year, consisting of 10 classes. Two classes were randomly selected as the research sample, namely class VIII-2 as the experimental class I, which was treated with realistic mathematics education approach with a jigsaw type cooperative learning, and class VIII-3 as the experimental class II, which was given the realistic mathematics education approach. The instruments used to collect data were creative thinking ability tests and self-regulated learning questionnaires. The validity of the contents of the instrument was determined by asking for the assessment of two experts (expert judgment) who stated that the instrument was suitable for use after revision. The tests used were independent sample t-test and hottelling T2. The results of the study show: (1) Learning using realistic mathematics education approach with a jigsaw type cooperative learning model has a significant effect on students' creative thinking abilities; (2) Learning using a realistic mathematics education approach with a jigsaw type cooperative learning model has a significant effect on self-regulated learning; (3) Learning using a realistic mathematics education approach with a jigsaw type cooperative learning model has a significant effect on students' creative thinking abilities and self-regulated learning.
