Abstract

AbstrakSebagian besar guru tidak memperhatikan kemampuan pemahaman matematis tetapi hanya terfokus pada hasil belajar siswa. Penelitian ini bertujuan untuk mengetahui dan menganalisis kemampuan pemahaman matematis siswa. Penelitian ini adalah penelitian kualitatif. Subjek penelitian adalah 25 siswa kelas IX2 SMP Negeri 1 Kampar Timur. Teknik pengumpulan data yaitu tes dan wawancara. Hasil analisis menunjukkan bahwa kemampuan pemahaman matematis siswa berkemampuan sedang dan rendah masih kurang, sedangkan siswa berkemampuan tinggi sudah cukup baik. Hasil wawancara menunjukkan bahwa siswa mengalami kesulitan dalam memberikan contoh dan bukan contoh dari konsep serta kesulitan dalam mengaitkan berbagai konsep karena tidak memahami konsep dan hanya menghapal rumusnya. Untuk meningkatkan kemampuan pemahaman matematis siswa berkemampuan sedang dan rendah, dalam menyampaikan konsep guru sebaiknya menyertakan contoh dan bukan contoh dari konsep serta memberikan latihan soal-soal tentang mengaitkan berbagai konsep. Analysis of Students’ Ability Mathematical Understanding on the Topic of Curved Side SpaceAbstractMost teachers do not pay attention to the ability of mathematical understanding but only focus on student learning outcomes. This study aims to determine and analyze students' mathematical understanding abilities. This research is qualitative research. The research subjects were 25 IX2 students from East Kampar 1 Middle School. Data collection techniques are tests and interviews. The results of the analysis show that the ability of mathematical understanding of students with moderate and low abilities is still lacking, while high-ability students are good enough. The results of the interview indicate that students have difficulty in giving examples and not examples of concepts and difficulties in relating various concepts because they do not understand the concept and only memorize the formula. To improve the ability of mathematical understanding of students with moderate and low ability, in conveying the concept the teacher should include examples and not examples of concepts and provide training questions about linking various concepts.

Abstract

This research was motivated by the low Mathematical Comprehension Ability (KPM) and Mathematical Problem Solving Ability (KPMM) of students and the absence of learning tools that can properly solve the problem of low KPM and KPMM. The products that is produced from this research are syllabus, lesson plans, and LKPD using discovery learning models with the context of Riau culture to improve students' KPM and KPMM. The development model used the Borg and Gall model. The validity instrument was in the form of a validation sheet for the syllabus, lesson plans, and student worksheet. Practicality instrument was used in the form of student response questionnaire. The data collection technique was carried out by validating learning devices and distributing response questionnaires to students. The data analysis technique used the analysis of validity and analysis of practicality. The average validation of the syllabus was 3.7; RPP, namely 3.54; and LKPD namely 3.51 with each category very valid. The average student response questionnaire in the initial field trial was 88.57 with the very practical category. The learning tools developed have been valid and practical to improve students' KPM and KPMM.

Abstract

The purpose of this study was to describe students' high initial ability, moderate initial ability, and low initial ability mathematical reasoning abilities. The reality in the field shows that students' mathematical reasoning skills in 3D materials are still low and still need to be improved. The subjects in this study were class XII students of SMKF Pekanbaru City totaling 32 students, Riau Province. The research method uses a qualitative descriptive approach. Data collection techniques using written tests, documentation, and interviews. Data analysis using qualitative descriptive analysis by preparing and organizing various kinds of student error data based on each indicator of mathematical reasoning. The results of the research on students' mathematical reasoning ability on each indicator in order are; (1) Presents mathematical statements in pictures 83.3%; (2) Provide reasons or evidence for one or more solutions 55.6%; (3) Make a guess 61.1%; (4) Draw conclusions from statements 63.9%; (5) Checks the validity of an argument 73.6%; and (6) drawing conclusions from several statements 56.5%. The results of this study indicate that mathematical reasoning ability in 3D material in this study 4 indicators are still classified as low. while 2 of them are classified as high.
