The subject of this research is student of class VII8 SMPN 14 Pekanbaru in academic years 2017/2018, which amounted to 35 students, consist of 17 boys and 18 girls. The research consist of two cycles, each cycle has four stages, which are planning, implementation, observation, and reflection. The instrument of data collection in this research consist of observation sheet and assessment sheet. Data collection techniques in this study consisted of observation techniques and test results of mathematics learning techniques. The analysis technique used is descriptive descriptive data analysis technique and descriptive statistical data analysis. Data obtained from the observation sheet is qualitative data and analyzed by descriptive quantitative analysis technique. Data obtained from the learning result test were analyzed by descriptive statistical analysis technique. The result of data analysis show teacher’s and student’s activity have been done very well in cycle II and weakness/deficiency that happened less from cycle I to cycle II. Implementation of PBL model enables students to observe and understand problems and can collect information related to problems given by teachers. The students 'mathematics learning outcomes also increased in UH I and UH II seen from the achievement of students' knowledge and skills and frequency distribution analysis.

Abstract: The background of this research was the low ability of students mathematical understanding which effect to the lower score of mathematics learning outcomes in junior high school. The type of this research is experimental research and using the static group comparison design. The population in this research were all grade IX students of SMP Negeri 1 Kampar Timur. The sample in this research consists of two class, where the IX1 as an experimental class and the IX2 as a control class. The aim in this research was to know the effect of implementation discovery learning model toward students mathematical understanding ability based on KD 3.7 Create the generalization of the surface area and the volume of curved side geometry (tube, cone, and ball), and KD 4.7 Complete the contextual problems which are related to the surface area and the volume of curved side geometry (tube, cone, and ball), and also the combination of some of the curved side geometries. The instruments in this research were mathematical early ability test and the mathematical understanding ability test (postest). The result of mathematical early ability test was used for determining the sample of class. The postest result was analyzed by nonparametric statistic test of Mann Whitney and the magnitude of the effect was calculated using the Cohen’s formula. The result of the research showed that implementation discovery learning model gave the positive effect toward the mathematical understanding ability. The implementation discovery learning model had a magnitude of the effect for 76% toward the students mathematical understanding ability at grade IX of SMP Negeri 1 Kampar Timur and included in the medium category.Key Words: Discovery Learning, Mathematical Understanding Ability.

Abstract: This research to improve the learning process and the students mathematical understanding skill by implementation cooperative learning model with the discovery method. The type of this research is classroom action research with two cycles. This research was conducted at class XI MIA 3 SMA Negeri 4 Kundur of the first semester to 24 students on 2019/2020 academic year on matrix material. The research instruments used mathematical learning instruments (syllabus, lesson plans, and student worksheets) and instruments for collecting data (observation sheets and mathematical understanding tests). Qualitative data were collected by observation technique with observation sheets which aimed to obtain data on the activities of teacher and students. Quantitative data was collected by a test technique using a mathematical understanding ability test kit that aimed to collected students mathematical understanding ability data. Base on the analysis of the observation sheets showed that the quality of implementation of learning process was improved at each meeting. Students have been more active in learning and their participation in increasing knowledge is also getting better. Result of the test indicated that the student’s learning achievement for the first was 48,14 improved in 1st cycle to 60,87 and improved to be 79,73 in 2nd cycle. Students qualification also improved for the 2nd cycle high qualification was 66,7%, medium qualification was 8,3% and low qualification was 25% when compared to 1st cycle that was high qualification was 33,3%, medium qualification was 33,3% and low qualification was 33,3% while the first high qualification was 25%, medium qualification was 12,5% and low qualification was 62,5%Key Words: Cooperative Learning, Discovery Method, Mathematical Understanding Skill

Faktor yang melatarbelakangi dilaksanakan penelitian ini yaitu pentingnya kemampuan pemecahan masalah matematis (KPMM), akan tetapi dalam prakteknya masih banyak ditemui siswa yang berkemampuan rendah dalam pemecahan masalah matematis. Maksud dari penelitian ini agar mampu memberikan gambaran terhadap pemecahan masalah matematis (KPMM) siswa dengan indikator memahami permasalahan, menyusun rencana pemecahan, melaksanakan rencana, dan melakukan pemeriksaan kembali. Metode yang digunakan ialah deskriptif kualitatif di mana subjeknya akan menggunakan siswa kelas VIII SMP Kecamatan Bukit Kapur berjumlah 60 orang. Instrumen penelitiannya berupa dua soal tes uraian. Untuk memperoleh informasi mendalam dilakukan wawancara terhadap tiga peserta didik yang kemampuannya heterogen dan dipilih dari seluruh siswa yang mengikuti tes. Hasil penelitian ini menunjukkan bahwa 23,67 persen siswa berkategori tinggi, 52,63 persen siswa berkategori sedang dan 23,7 persen siswa berkategori rendah. Rendahnya pemecahan masalah matematis siswa dipengaruhi oleh faktor kurangnya kemampuan memahami masalahsulit menentukan cara memecahkan masalah, sulit menentukan penggunaan rumus, sulit melakukan penyelesaian tahapan perhitungan, dan tidak pernah melakukan pengecekan kembali pada jawaban yang didapatkan.
