This study aims to determine the effect of the Implementation of Guided Inquiry Learning Model Against the Mathematical Understanding Ability of Class VIII Students of MTs Al Islam Petalabumi. The type of this research is Quasi Experiment research. The research design used was Randomized Subjects Posttest Only Control Group Design. The sampling technique is a purposive sampling technique. The instrument in this study was a test of students' mathematical concept comprehension ability. Data analysis techniques in this test use the Independent Samples T-Test. Based on the results of research testing the hypothesis of the two sample classes obtained P-value is smaller than a, which is 0,000 <0.05. This means that H0 is rejected and Ha is accepted. Thus the ability to understand students 'mathematical concepts with the application of guided inquiry learning models is better than the ability to understand students' mathematical concepts with conventional learning models.

In solving the problems they face, students must think so that they can apply the right concepts to the problems they face. This process can run effectively in learning if students have good reflective thinking skills. Mathematical reflective thinking is one of the thought processes needed in the process of solving mathematical problems. The purpose of this study was to determine the increase in reflective thinking skills between students who received learning with problem-based learning and conventional learning. The research method used is quantitative research with a quasi-experimental design. The population of this study was students of grade 7 MTs Islmaiyah Medan in the academic year 2019/2020. The sample in this study was students of class 7-A and 7-B MTs Islamiyah Medan. The data were collected by giving a reflective thinking ability test instrument. The data obtained were analyzed using a two-way ANOVA statistical test. Based on the research findings, it was found that there was an increase in students' reflective thinking skills taught by problem-based learning with students taught conventionally. Where the increase in reflective thinking skills between students whose learning process using problem-based learning is significantly higher than students whose learning is through conventional learning. Based on these results, it can be concluded that in an effort to foster students' mathematical abilities, the learning model used must match the characteristics of the learning model with mathematical abilities.

PENGARUH PENGGUNAAN MODEL LEARNING STARTS WITH A QUESTION TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA Mustika Helma; Gigin Saipul Rahma

The study began with observations at VIII Rengat Barat Middle School students of class VIII. This study aims to determine students' mathematical problem solving abilities using the Learnig Starts With A Question model. This type of research is experimental research (experimental research) with a quasi-experimental design research design. The research design used was The Randomized posttest-only control design. The sampling technique uses Simple Random Sampling. In this study the instrument used was a test of students' mathematical problem solving abilities. Data obtained on the problem-solving ability test were analyzed using the Independent Samples T-Test based on the results of the hypothesis test, the value of tcount = 2.014 and ttable = -1.999 with (df) n-2 and significance <0.05 (0.048 <0.05). As for the Independent Samples T-Test testing criteria, reject H0 if t> t table. Based on that, H0 is rejected because tcount = 2,014> ttable = -1,999. So it can be concluded that the students 'mathematical problem solving ability using the Learning Starts With A Question learning model is better than the students' mathematical problem solving ability using the conventional model in class VIII of SMP Negeri 4 Rengat Barat. Keywords: Problem Solving, Learnig Starts With A Question

PENINGKATAN KEMAMPUAN BERPIKIR LOGIS DENGAN MENGGUNAKAN METODE PEMBELAJARAN KOOPERATIF TIPE TEAM-ACCELERATED INSTRUCTION Dwi Maulida Sari; Rizky Nurul Hafni

This study is a quasi-experimental study with a pretest-posttest one group design. The population in this study is all students majoring in mathematics education at an Asahan University, North Sumatra. Sampling was done by using the purposive sampling technique. Students work under the cooperative learning method Team-Accelerated Instruction (TAI) type. This research was conducted to study the enhancement of students’ logical thinking ability after cooperative learning TAI types were implemented. The instruments used in this study are logical thinking ability tests, observation sheets, and student interviews. The data were analyzed by using t-test. From the result of data analysis, it is found that there is a significant enhancement in the logical thinking ability of the students’ who work under the cooperative learning method TAI type. Therefore, cooperative learning Team-Accelerated Instruction (TAI) type can be alternative learning to improve students’ logical thinking ability.

PENERAPAN PENDEKATAN PEMBELAJARAN MATEMATIKA REALISTIK TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA Ade Evi Fatimah

Realistic mathematics learning is learning that connects and engages the surrounding environment and real experiences that students have experienced in everyday life. The objectives of this study were (1) to find out how to apply realistic mathematics learning approaches to students' problem-solving abilities in fractions material. (2) To determine student learning activities on the application of realistic mathematics learning approaches to students' problem-solving abilities on fraction material. This study uses a descriptive analysis. The subjects in this study were 7th-grade students of SMP Tunas Pelita Binjai, while the objects in this study were the students' problem-solving abilities and student activities during learning. Based on the results of the analysis, it was obtained (1) The application of a realistic mathematics learning approach to students' problem-solving abilities on fractions in Grade 7 was to present contextual problems about fractions, solve contextual problems about fractions, then compare and discuss answers and conclude learning. Based on the learning process, a percentage of 80.55% of students obtained problem-solving abilities above the low category. This shows that the realistic mathematics approach is effective for building students 'problem-solving abilities. (2) Student learning activities on the application of realistic mathematics learning approaches to students' problem-solving abilities on fraction material in Grade 7 are in the good category with a final score of 80.14. So it can be suggested that in the teaching and learning process it is expected that the teacher uses a realistic mathematics learning approach.

PERBEDAAN PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH MATEMATIS DENGAN PENDEKATAN CONTEXTUAL TEACHING AND LEARNING DI KELAS X SMA NEGERI 2 PEMATANGSIANTAR Winmery Lasma Habeahan

The purpose of this study was to determine the differences in the improvement of students' mathematical problem-solving abilities with the Contextual Teaching and Learning approach in the material of the two-variable linear equation system in class X SMA Negeri 2 Pematangsiantar. This study used an experimental method with the aim of being in accordance with the previous statement to determine the difference in students' mathematical problem-solving abilities with a contextual approach and an expository approach, with a randomized pretest-posttest control group design. The average increase in problem-solving abilities in the control class was 0.1688 while the increase in problem-solving abilities in the experimental class was 0.0085. By using the t-test (SPSS), with a value of Fcount = 10.907 and a significant level of 0.05, a significant probability is obtained 0.002 <0.05, it can be concluded that there is a difference in normalized gain or an increase in problem-solving ability with conventional and contextual approaches. Based on the average gain of the control and experimental classes, the increase in the control class using the conventional approach is higher than the experimental class with the contextual approach. The difference in increasing problem-solving abilities in conventional classrooms is possible due to differences in students' entry-level abilities, which can be seen in the average pretest of each class.
