The representation and mathematical problem-solving abilities of students are still relatively low. The low ability is due to the lack of attention of the implementers of learning to develop learning that can improve the ability of representation and mathematical problem-solving. One effort that can be done is to apply to learn through the Concrete Representational Abstract (CRA) approach. This study aims to analyze the increase in representation ability and mathematical problem solving of students and to examine the interaction between student learning and the ability of representation and mathematical problem solving of students. This research is quantitative research with an experimental method with the design of the pretest-posttest group design. The population of this study was all students of SMP Negeri 1 Banda Aceh with a sample of two classes which became the experimental and control classes. The instrument of data collection is a test of representation ability and mathematical problem-solving. Data analysis of the study was carried out with SPSS 23 assisted two-way ANOVA for windows at a significant level of 0.05. The results of the study showed that: 1) the improvement of the representation and mathematical problem-solving abilities of students who obtained learning through the CRA approach was better than improving the problem-solving abilities of students who obtained conventional learning 2) there was no interaction between the CRA approach and the student level towards improving representation and solving abilities mathematical problem

This research is an experimental research that aims to determine and measure the effect of applying the Missouri Mathematic Project (MMP) learning model to students' mathematical problem solving abilities. This type of research is quantitative research with one group pretest-posttest design. The population in this study were VII grade students of SMP Negeri 4 Bantimurung with 33 random samples taken in one experimental class. Data collection uses tests of students' mathematical problem solving abilities that have been validated by experts. The data of this study were analyzed descriptively and inferentially by the normality test as a test of the prerequisite for analysis. The results of data analysis showed that the average pre-test was 42.09 while the post-test average was 83.73. The average gain normalized score is 0.72 in the high category and is normally distributed for mathematical problem solving ability data. Based on the t-test it can be concluded that there is a significant increase that affects students' mathematical problem solving abilities by applying the Missouri Mathematic project (MMP) learning model.

AbstrakKemampuan pemecahan masalah tidak lepas dari kegiatan belajar mengajar pada umumnya karena keberhasilan seseorang terhadap sesuatu yang dihadapi tidak lepas dari matematika. Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah matematis peserta didik kelas IX di SMP Negeri 15 Palembang. Sampel pada penelitian ini di ambil secara acak yaitu peserta didik kelas IX.1 berjumlah 31 peserta didik yang dilakukan di SMP Negeri 15 Palembang tahun Pelajaran 2019/2020. Teknik pengumpulan data menggunakan soal tes berbentuk uraian materi bangun ruang (kubus dan balok). Teknik analisis data dalam penelitian ini adalah deskriptif kuantitatif. Dari hasil analisis data dan pembahasan maka dapat disimpulkan bahwa kemampuan pemecahan masalah matematis peserta didik dikategorikan rendah.  Analysis of Mathematical Problem-Solving Ability on Cubes and Blocks in Junior High SchoolAbstractThe ability to solve problems cannot be separated from teaching and learning activities in general because one's success in something that is faced cannot be separated from mathematics. This study aims to determine the mathematical Problem-solving abilities of grade IX students at SMP Negeri 15 Palembang. The sample in this study was taken randomly. namely students of class IX.1, totaling 31 students which were conducted at SMP Negeri 15 Palembang for the 2019/2020 academic year. The data collection technique used test questions in the form of a description of the material (cubes and cuboids). The data analysis technique in this research is descriptive quantitative.

This study aims to determine the effect of the use of the super-scaled model of scaffolding on students' mathematical problem solving abilities. The sampling technique used was cluster random sampling with 3 classes namely experimental class 1 (the class was treated with scaffolding assisted superememe learning model), experimental class 2 (superitem learning only) and control class (the conventional treatment class). Hypothesis testing used is anava 1 cell path is not the same. The results of the study found that there were differences in students' mathematical problem solving abilities by using learning models of scaffolding assisted supermarkets. Furthermore, the mathematical problem solving ability of students with the super-intensive learning model assisted by scaffholding is the same as the mathematical problem-solving ability of students using superemit learning models. The mathematical problem solving ability of students with superficial learning models assisted by scaffholding is better than the students' mathematical problem-solving abilities using conventional learning models. Furthermore, the mathematical problem solving ability of students with superemit learning models is the same as the mathematical problem solving ability of students using conventional learning models.

This study aims to find out "the effectiveness of guided discovery models by using super-task tasks on the development of students' mathematical problem solving abilities". This research is designed by using posttest only control which the research subject is first year students of 2018/2019 academic year. This research uses saturated sampling technique because all members of the population are used as samples. Data collection techniques in this study only use test instruments. Data analysis technique was done by using t-test. The results of the data analysis obtained that hypothesis testing in the experimental and control class obtained t calculation  = 3.41 with t table = 1.67. Because t calculation > t table then H0 is rejected so that it can be concluded that the guided discovery learning model by using superchemical tasks is more effective than the direct learning model on mathematical problem-solving abilities of first-level students in school mathematics II even semester at IKIP PGRI Bojonegoro.   Penelitian ini bertujuan untuk mengetahui “efektivitas  model penemuan terbimbing dengan menggunakan tugas superitem terhadap pengembangan kemampuan pemecahan masalah matematika mahasiswa”. Penelitian ini merupakan penelitian dengan desain yang digunakan adalah posttest only control  dimana subyek penelitiannya adalah mahasiswa tingkat I tahun ajaran 2018/2019. Penelitian ini menggunakan teknik sampling jenuh karena semua anggota populasi dijadikan sebagai sampel. Teknik pengumpulan data dalam penelitian ini hanya menggunakan instrument tes. Teknik analisis data menggunakan uji–t. Hasil dari analisis data diperoleh uji hipotesis pada kelas eksperimen dan kontrol diperoleh thitung= 3,41 dengan ttabel = 1,67. Karena   thitung > ttabel maka H0 ditolak sehingga dapat disimpulkan bahwa model pembelajaran penemuan terbimbing dengan menggunakan tugas superitem lebih efektif  dibandingkan dengan model pembelajaran langsung terhadap kemampuan pemecahan masalah matematika mahasiswa tingkat I pada mata kuliah matematika sekolah II semester genap di IKIP PGRI Bojonegoro.

This study aims to determine the effect of Thinking Aloud Pair Problem Solving (TAPPS) learning model on mathematical problem solving abilities in the form of algebra material. This type of research is a quasi experiment with the posttest only design with a nonequivalent group. The population in this study were 7th grade students of SMPN 1 Mataram in the academic year of 2019/2020. Sample determination using purposive sampling technique, where the sample of this study is students of class VII-I as an experimental class and students of class VII-H as a control class. In the experimental class applied the TAPPS learning model and control class applied the direct learning model. The instrument used in this study was a test of mathematical problem-solving abilities (posttest) on algebra form material. Quantitative data analysis was performed using t-test. The results of the data analysis showed that there are significant differences in students' mathematical problem solving abilities between the classes that get the TAPPS learning and direct learning. This suggests that learning with the Thinking Aloud Pair Problem Solving (TAPPS) model affects the ability to solve mathematical problems in the form of algebra material.
