Abstract:The problem solving and productive disposition ability of students is still low due to the inaccuracy of the learning model used by teachers in learning mathematics. This study aims to determine the effectiveness of the Means-Ends Analysis (MEA) learning model in developing students' problem solving and productive disposition abilities. This type of research is pre-experimental research with One-Group Pretest-Posttest Design. The data analyzed are the results of students' mathematical problem solving and productive disposition data of students after learning using the Means-Ends Analysis (MEA) learning model. From the results of this study, it can be seen that the Means-Ends Analysis (MEA) learning model is effective in developing students' problem solving and productive disposition abilities with the effectiveness criteria: (1) The results of students' problem-solving abilities are categorized to be effective both descriptively and inferentially in terms of posttest scores, normalized gain, and classical completeness. (2) The productive disposition of students is categorized effectively both descriptively and inferentially in terms of the score of productive disposition and increase in productive disposition. Abstrak:Rendahnya kemampuan problem solving dan productive disposition peserta didik disebabkan oleh ketidaktepatan model pembelajaran yang digunakan oleh guru dalam pembelajaran matematika. Penelitian ini bertujuan mengetahui keefektifan model pembelajaran Means-Ends Analysis (MEA) dalam menumbuhkembangkan kemampuan problem solving dan productive disposition peserta didik. Jenis penelitian yang digunakan adalah pre-experimental dengan desain One-Group Pretest-Posttest Design. Data yang dianalisis adalah hasil problem solving dan productive disposition peserta didik setelah pembelajaran matematika dengan menggunakan Means-Ends Analysis (MEA). Dari hasil penelitian ini diperoleh bahwa Means-Ends Analysis (MEA) efektif dalam menumbuhkembangkan kemampuan problem solving dan productive disposition peserta didik dengan kriteria keefektifan: (1) Hasil kemampuan problem solving peserta didik dikategorikan efektif baik secara deskriptif maupun secara inferensial yang ditinjau dari: skor posttest, gain ternormalisasi, dan ketuntasan klasikal. (2) Productive disposition peserta didik dikategorikan efektif baik secara deskriptif maupun secara inferensial yang ditinjau dari: skor productive disposition dan peningkatan productive disposition.

AbstrakPerlu adanya upaya guru untuk meningkatkan kemampuan pemecahan masalah matematis siswa, karena fakta di lapangan menunjukkan rendahnya kemampuan matematis siswa tersebut. Salah satunya penggunaan model pembelajaran kooperatif tipe Think Pair Share dan Think Talk Write. Penelitian ini dilakukan untuk menganalisis perbedaan peningkatan kemampuan pemecahan masalah matematis siswa antara yang mendapatkan model pembelajaran kooperatif tipe Think Pair Share dan Think Talk Write. Metode penelitiannya adalah kuasi eksperimen. Populasi penelitian yaitu seluruh siswa kelas VII MTs Negeri 1 Garut, dengan sampel sebanyak dua kelas yang terdiri dari 46 siswa. Instrumen penelitian yang digunakan berupa tes uraian. Analisis data diawali dengan uji gain ternormalisasi, uji normalitas data gain ternormalisasi, kemudian uji Mann Whitney. Berdasarkan hasil analisis secara statistik diperoleh kesimpulan bahwa terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis siswa antara yang mendapatkan model pembelajaran Think Pair Share dan Think Talk Write. The Differences in Improving Students of Mathematical Problem Solving Ability Between Think Pair Share and Think Talk Write AbstractTeachers need help to improve students 'mathematical problem-solving skills because the facts in the field show the students' low mathematical ability. One of them is the use of Think Pair Share and Think Talk Write cooperative learning models. This research was conducted to analyze the differences in the improvement of students' problem-solving skills between those who get the cooperative learning model Think Pair Share and Think Talk Write types. The research method is quasi-experiment. The study population was all grade VII students of MTs Negeri 1 Garut, with a sample of two classes consisting of 46 students. The research instrument used was a description test. Data analysis begins with the normalized gain test, the normalized normality gain data test, then the Mann Whitney test. Based on the analysis results obtained from the research results obtained from the comparison between students' mathematical problem solving between those who get the Think Pair Share learning model and Think Talk Write.

      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.

Introduction: Mathematical problem solving ability is very important in mathematic learning, because is can help students to solve daily life problems better. But the students mathematical problem solve ability is not high yet, one of the factor is because many students only know the standard procedures of solving mathematics problems, and when the given problem are different from the examples they tend to give up easily. This comparative design study aims to find out the improvement of students mathematical problem solving ability using Missouri Mathematics Project (MMP) learning model with individual assignments and small group assignments, and to find out whether there are differences between those two. Method: The sample in this study was VII grade students at SMP Advent Cimindi and SMP Advent II Bandung, Bandung. The instruments used in the study are mathematical problem solving test and questionnaire for response toward the Missouri Mathematics Project (MMP) learning model as the non-test instrument. Result: The results showed that the improvement of mathematical problem solving abilities of students who obtained the Missouri Mathematics Project (MMP) learning model with individual assignments and students who obtained the Missouri Mathematics Project (MMP) learning model by assigning small groups was categorized as high. Statistically, there is a significant difference in the students mathematical problem solving improvement after being taught using Missouri Mathematics Project (MMP) learning model, between students who get individual assignments and small group assignments. The response questionnaire result shows that students who acquire individual assignments like the Missouri Mathematics Project (MMP) learning model, more further the students who acquire group assignments really like the Missouri Mathematics Project (MMP) learning model.
