      This study aims to determine the effect of the Type STAD Cooperative Learning model on mathematical problem solving abilities. The data collection technique was obtained by means of a test in the form of description questions and documentation in the form of a list of student names. The research instrument used was 3 pre-test and post-test questions. The data analysis technique used is the normality test, homogeneity, t test with the technique of paired samples t-test and independent t-test.      The results showed that, the paired sample t-test on the problem solving ability before and after treatment with STAD obtained an average value of 50.29 to 83.71 with a significance of 0.000 <0.05. This means that the students' scores before and after STAD learning have differences in the average mathematical problem solving abilities. Based on the results of the paired sample t-test on the ability to solve mathematical problems before and after treatment using conventional learning models, the average value was 44.57 to 75.79 with a significance of 0.000 <0.05. This means that there is a significant increase before and after conventional learning. Based on the results of the independent samples t-test, the mean values were 83.71 and 75.79 with a significance value of 0.009 <0.05. This means that there is a difference in the average problem-solving ability of students in STAD learning with students in conventional learning. It can be concluded that the STAD type of cooperative learning model has an effect on students' problem solving abilities in mathematics.

AbstrakRendahnya kemampuan pemecahan masalah matematika siswa menyebabkan siswa kurang mampu menyelesaikan soal yang bersifat non rutin dan siswa masih kurang mengembangkan ide dan kemampuan yang dimilikinya. Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah matematika siswa melalui model Problem Based Learning berdasarkan Kemampuan Awal Matematika (KAM) siswa. Metode penelitian yang digunakan adalah kualitatif. Hasil penelitian ini menunjukkan bahwa kemampuan pemecahan masalah matematika siswa melalui model Problem Based Learning menjadi lebih baik. Sampel dalam penelitian ini adalah siswa kelas VIII-7 SMP Negeri 12 Padang yang terdiri dari 32 orang. Siswa yang awalnya berkemampuan rendah meningkat menjadi siswa berkemampuan sedang dengan peningkatan sebesar 75 %. Siswa yang awalnya tergolong berkemampuan sedang meningkat menjadi siswa berkemampuan tinggi sebesar 26 %. Siswa sudah mampu 1) memahami masalah, 2) menyusun rencana penyelesaian, 3) melaksanakan penyelesaian, dan 4) mengecek kembali jawaban. Analysis of Students' Problem Solving Abilities Based on Early Mathematical Ability AbstractThe lack of students' mathematical problem-solving skills causes students to be less able to solve problems that are non-routine and students are still lacking in developing their ideas and abilities. This study aims to determine students 'mathematical problem-solving abilities through the Problem Based Learning model based on students' Early Mathematical Ability (KAM). The research method used is qualitative. The results of this study indicate that students' mathematical problem-solving abilities through the Problem Based Learning model are better. The sample in this study were students of class VIII-7 Middle School 12 Padang consisting of 32 people. Students who were initially low-skilled increased to moderate-capable students with an increase of 75%. Students who were initially classified as capable were increasing to high-ability students by 26%. Students can 1) understand the problem, 2) draw up a settlement plan, 3) carry out the solution, and 4) re-check the answers.

This research is aimed to investigate the students’ problem-solving competency after learn by using discovery learning model and students’ problem-solving ability after learn by using problem-based learning model. Therefore, this research is aimed to investigate differences problem-solving ability of mathematics between students who get discovery learning model and problem-based learning model. The population used in this research was a student in grade VII in one of junior high school in West Bandung Regency. The sample was student class VII B for the first experiment class and VII C for the second experiment class with 35 students in every class. The method in this research was a quasi experiment by using two group post-test only design. The instrument in this research is post-test about problem-solving of mathematics. Based on the research, it can be concluded that there is a difference between the mathematical problem-solving competency of students who get discovery learning model and problem-based learning model. Nevertheless, the qualification of problem-solving competency between of students who gets discovery learning model and problem-based learning model, are including the medium category

This study aims to determine the effect of using student worksheet (LKPD) based on the Problem Based Learning model on the mathematical problem solving abilities of students of class VIII SMP Negeri 2 Pangean. This type of research was a quasi-experimental study with a pretest – posttest control group design. The population was all students of SMP Negeri 2 Pangean Indonesia in the 2019/2020 school year. Sampling method was using random sampling technique. Based on the results of data analysis, the posttest mean score in the experimental class was 85.45 and the average value in the control class was 54.5, meaning that the average value of the experimental class was higher than the control class. The two-mean difference test using the t test was significant (2-tailed) 0.000 <α = 0.05, which means that the posttest score of students 'mathematical problem solving abilities was different from the average posttest score of students' mathematical problem solving abilities. which uses scientific learning. So it can be concluded that there is an effect of the Problem Based Learning model on students' mathematical problem solving abilities.
