Problem solving ability is a very important ability possessed by students in solving school mathematics problems. The purpose of this study is to determine the mathematical problem solving ability of students who use the Search, Solve, Create and Share (SSCS) learning model and the students who study with conventional learning. This research was a quasi-experimental study with a non equivalent control group design. The subjects in this study were all Kampar Junior High School students. The analysis technique used was the One-Way Anova Test and Two-Way Anova Test. The results showed the mathematical problem solving ability of students who learned to use the SSCS model was better than students who learned to use conventional learning models. However, there is no interaction observed between SSCS learning model and students mathematical problem solving ability (KPMM) level on students' mathematical problem solving abilities in Kampar Regency

This study aimed to examine comprehensively the effect of the application of REACT learning models based on the Malay cultural context of Riau on students’ mathematical problem-solving abilities. The research was a quasi-experimental research with Pretest-post-test control group design. The sample of this study was all students of class VII SMP 12 Pekanbaru. The results of data analysis were: (1) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning; (2) There was a difference of the mathematical problem-solving ability of Pekanbaru junior high school students between who learned to use REACT learning models based on the Malay cultural context of Riau and students who studied with conventional learning in terms of aspects of student ability levels, (3) There was no interaction between the learning model and the level of students’ ability to the ability to solve mathematical problems; (4) There was a difference in the mathematical problem-solving ability of Pekanbaru junior high school students who learned to use the REACT learning model based on the Malay Malay cultural context in terms of aspects of student ability levels.
