Understanding mathematical concepts is an important ability to be mastered by students. It allows students to understand the essence of teaching and the material being learned. The purpose of the study is to analyze how mathematical concept understanding of students who learn by using constructivism-approach textbooks that have been developed in previous studies. This research was a descriptive study with a qualitative approach. The study was conducted by giving 10 item problems of conceptual understanding to participants that consisting of 17 students STKIP PGRI Sumatera Barat in Basic Mathematics subject. Furthermore, the students' answers were analyzed descriptively. The results of the study showed that a mastery achievement of the highest mathematical concept understanding was on indicators of using model, diagram, and symbols to represent a concept. While the lowest concept mastery was on indicators of recognizing conditions for determining a concept, students had difficulty in determining a settlement set from an inevitable inequality of absolute value.

This research was backgrounded by teaching materials used in the Private Ma mus Canduang, Agam Regency in the form of LKS and still unable to make students active in the learning process. This study aims to determine the practicality of the Student Worksheet (LKPD) based on a scientific approach to class XI matrix material. One of the materials that is difficult for students to understand is in matrix material. A common error is the wrongness of putting the matrix element. The research conducted was development research using the Plomp model which consisted of three stages, namelypreliminary research, prototyping phase, and assessment phase. This research was carried out until the prototyping phase, namely in practicality testing. The results of the LKPD validity test based on the scientific approach by the validator obtained a value of 86.8% with very valid criteria and the results of LKPD practicality based on a scientific approach obtained a value of 90.13% with very practical criteria. Based on the results of the study, it can be concluded that LKPD based on a scientific approach to the matrix material of class XI private MA students of MUS Canduang is very valid and very practical.Penelitian ini dilatarbelakangi oleh bahan ajar yang digunakan di MA Swasta MUS Canduang Kabupaten Agam yang berupa LKS dan masih belum dapat membuat siswa aktif dalam proses pembelajaran. Penelitian ini bertujuan untuk mengetahui kepraktisan Lembar Kerja Peserta Didik (LKPD) berbasis pendekatan saintifik pada materi matriks kelas XI.

This study aims to produce a valid and reliable test instrument that can measure students' problem solving abilities. The type of research used is research and development (R&D), namely the development of test instruments to measure mathematical problem solving abilities. The development model used is the Plomp model which consists of 3 phases: 1) Preliminary Research, 2) Prototyping Phase, 3) Assessment Phase. The test subjects in this study were eighth grade students of SMP Negeri 12 Padang, totaling 9 students. Based on the experiments carried out, it was found that: 1) the mathematical problem solving test instrument was said to be "valid" because based on the results of the CVR, namely 1, it met the criteria of 0.99 and the CVI was 1 with a very suitable category in the range of 0.68 - 1, 00. 2) The mathematical problem solving test instrument has a difficulty level with an average of 0.62 with the medium category in the range of 0.31-0.70. 3) The mathematical problem solving test instrument has a good discriminatory power with an average discriminating power of 0.52 with a sufficient category in the range of 0.41 – 0.70. 4) The mathematical problem solving test instrument is said to be reliable with a value of 0.8702 with a very high reliability category, in the range of 0.80 < r11 1.00. Thus, the test instrument for mathematical problem solving skills on the number pattern material is said to be valid and reliable.Penelitian ini bertujuan untuk menghasilkan sebuah instrumen tes yang valid dan reliabel yang dapat mengukur kemampuan pemecahan masalah peserta didik.

This research is motivated by the number of errors made by students in solving math problems. The purpose of this study was to determine the types of errors made by students in working on math problems based on Watson's criteria in class IX.8 and to determine the factors that caused students to make mistakes in doing math problems based on Watson's criteria in class IX.8. The research method used is descriptive method with a qualitative approach. The sampling technique used is purposive sampling technique. The sample in this study consisted of 32 students, for further research from the existing sample, namely 5 students according to the level of academic ability and certain considerations. The results of this study indicate that the types of errors made by students with high academic abilities are incorrect procedures and missing conclusions. The types of errors of moderate ability students are missing data, wrong procedures and missing conclusions. The types of errors made by students with low academic ability are inaccurate data, wrong procedures, missing data and missing conclusions. The cause of students making mistakes is that students do not understand the questions, students are confused in answering questions and forget to use the correct formula. So it can be said that the error in reading mathematical stories is in accordance with Watson's Criteria.
