Abstract

Pemahaman konsep matematis penting dimiliki oleh siswa karena sebelum melanjutkan ke materi yang lebih sulit. Penelitian ini bertujuan untuk mendeskripsikan pemahaman konsep matematis siswa SMP kelas VIII pada materi bentuk aljabar. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif. Populasi penelitian adalah kelas VIII SMPN 1 Ampek Angkek. Sampel penelitian adalah kelas VIII di SMP Negeri 1 Ampek Angkek adalah 148 siswa SMP Negeri 1 Ampek Angkek. Sampel dipilih menggunakan teknik purposive sampling. Instrumen penelitian adalah tes uraian pemahaman konsep yang terdiri dari 8 soal setiap soal mewakili setiap indikator pemahaman konsep, wawancara, dan dokumentasi. Data dari hasil penelitian berdasarkan masing-masing kategori pemahaman konsep matematis untuk kategori tinggi memiliki persentase 16%, kategori sedang memiliki persentase 66% , dan kategori rendah memiliki persentase 18%. Maka disimpulkan bahwa pemahaman konsep matematis siswa di kelas VIII SMP Negeri 1 Ampek Angkek berada di kategori sedang.

Abstract

Starting from the low understanding of mathematical concepts of prospective teacher students in learning and the demands of the times. Prospective teachers must first understand mathematical concepts in order to easily solve more complex mathematical problems. Preliminary studies show that prospective teachers' understanding of mathematical concepts in analytical geometry is still low. Students have difficulty describing abstract geometric objects and lack access to adequate interactive learning materials, making it difficult for them to understand geometry. Teaching materials are needed in the form of metacognitive-based electronic models to improve students' understanding of mathematical concepts. This e-module supports an independent learning process that leads students to abstract mathematical problems using the help of GeoGebra. This research was conducted with the Plomp development model, to measure the level of practicality seen from the practicality questionnaire from 9 students and a lecturer teaching the Analytical Field Geometry course, and the effectiveness of the product has been seen from the small group evaluation phase. Measurement of effectiveness is measured from the average n-gain according to Meltzer to improve students' understanding of mathematical concepts. The results showed that the GeoGebra-assisted metacognitive-based electronic flipbook module to improve students' understanding of mathematical concepts was practice and effective.

Abstract

Mathematical conceptual understanding is essential for students, as it facilitates their ability to progress to more complex material. The aim of this study is to describe the mathematical conceptual understanding of tenth-grade high school students on the topic of exponents and logarithms. This research employs a qualitative descriptive approach using purposive sampling, involving 136 students at SMAN 7 Padang. The research instruments include an essay test on mathematical conceptual understanding consisting of 8 questions, each representing an indicator of conceptual understanding three of which are word problems as well as documentation. The results show that based on each category of mathematical conceptual understanding, the high category has a percentage of 20.59%, the medium category 62.5%, and the low category 16.91%. It can be concluded that the mathematical conceptual understanding of tenth-grade students at SMAN 7 Padang falls within the medium category.
