      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.

Berdasarkan hasil analisis uji anava satu jalur, dengan signifikan 0,05 diperoleh 𝐹ℎ𝑖𝑡𝑢𝑛𝑔 = 𝐹𝑡𝑎𝑏𝑒𝑙 = 0,34, maka H0 ditolak. Artinya ada perbedaan signifikan rata-rata kemampuan penalaran matematis siswa pada kelas eksperimen 1, kelas eksperimen 2, dan kelas kontrol. Berdasarkan uji beda nyata (BNT) menunjukan bahwa pembelajaran yang memberikan hasil penalaran matematis yang berbeda adalah model pembelajaran discovery learning dengan konvensional, dan model kooperatif tipe jigsaw dengan konvensional. Sedangkan pembelajaran dengan model discovery learning dan model kooperatif tipe jigsaw tidak memberikan hasil kemampuan penalaran matematis siswa yang berbeda. Model discovery learning dan model kooperatif tipe jigsaw memberikan hasil lebih baik bila dibandingkan dengan model konvensional.Kata kunci: kemampuan penalaran matematis, model discovery learning, model Jigsaw AbstractThe purpose of this study was to determine students' mathematical reasoning abilities with discovery learning models and jigsaw type cooperative learning models.

Through classroom action research, researchers seek to improve students 'mathematical problem solving abilities on mathematical induction material by using nested integrated learning methods and explore students' attitudes towards the application of the given learning model. The study was conducted during two cycles which included four stages of learning, namely: planning, implementation, observation, and reflection. The study was conducted in the odd semester of the 2019/2020 school year involving 34 students of class XI MIPA-2 SMAN 1 Garawangi, Kuningan. There are 2 types of research instruments used, namely tests and questionnaires. Based on the test results, it can be seen that in the post-test, the N-Gain index obtained was 0.61 (moderate). Meanwhile, based on the results of the questionnaire, it can be seen that 100% of students show a positive attitude. Thus, it can be concluded that the nested type integrated learning model can improve students' mathematical problem solving abilities on mathematical induction material and get a good appreciation with the presence of a positive attitude shown by all participants.
