Abstract

Tujuan dari penelitian ini adalah untuk mendeksripsikan kemampuan pemahaman konsep matematika siswa dalam penerapan model pembelajaran Kooperatif Learning Tipe Think Pair Share (TPS) berbantuan Geogebra. Penelitian ini dilakukan dengan menerapkan model pembelajaran think pair share (TPS) dengan menggunakan geogebra sebagai bantuan dalam proses pembelajaran. Subjek penelitian ini merupakan peserta didik kelas VIII berjumlah 29 orang. Jenis penelitian ini ialah penelitian tindakan kelas (PTK) yang terdiri dari 2 siklus, dimana setiap siklus terdiri dari 2 kali pertemuan dalam pembelajaran dan 1 pertemuan untuk mengukur kemampuan pemahaman konsep siswa dan mengukur respon siswa terhadap pembelajaran yang telah dilakukan. Hasil penelitian menunjukkan kemampuan pemahaman konsep meningkat setelah dilaksanakannya pembelajaran model think pair share (TPS) berbantuan geogebra. Terdapat peningkatan kemampuan pemahaman konsep yang dapat diamati dari data rata-rata peserta didik sebelum diberikan tindakan, yaitu sebesar 29,3 yang dikategorikan sebagai sangat rendah, dengan ketuntasan klasikal mencapai 0%. Namun, setelah diberikan tindakan pertama, rata-rata kemampuan pemahaman konsep siswa meningkat menjadi 75,12 dengan persentase ketuntasan klasikal sebesar 72,41%. Pada tindakan kedua, terjadi peningkatan lebih lanjut hingga mencapai rata-rata 88,42 dan persentase ketuntasan klasikal mencapai 86,20%. Berdasarkan hasil penelitian, dapat disimpulkan bahwa penerapan model pembelajaran Kooperatif Learning Tipe Think Pair Share (TPS) berbantuan Geogebra mampu meningkatkan kemampuan pemahaman konsep siswa kelas VIII di SMP Negeri 2 Pantai Labu.

Abstract

This study aims to analyze students' mathematical problem-solving difficulties in terms of learning styles using the GeoGebra-assisted problem-based learning model. This study uses a descriptive qualitative approach. The subjects of the study consisted of 32 eighth-grade students grouped based on learning styles, namely accommodation, divergent, assimilation, and convergent. Data collection techniques were carried out through learning style questionnaires, mathematical problem-solving ability tests, and interviews. Data analysis was carried out through data reduction, data presentation, and drawing conclusions based on difficulty indicators, namely difficulties in facts, concepts, principles, and operations, which were associated with the stages of Polya's problem-solving. Based on the results of the study of 32 students, it was found that students with an accommodation learning style numbered 7 students (21.87%), a divergent learning style numbered 11 students (34.37%), an assimilation learning style numbered 9 students (28.12%), and a convergent learning style numbered 5 students (15.62%). From the results of interviews with students, for the accommodation of learning style, they experienced difficulties in the concept, principle, and operation indicators. Students with a divergent learning approach experience difficulties with indicators of concepts, principles, and operations. Students with an assimilation learning style experience difficulties with indicators of facts, principles, and operations. Students with a convergent learning style experience difficulties with indicators of principles and operations.

Abstract

Line integrals are one of the fundamental concepts in advanced calculus used to determine the accumulation of a quantity along a specific path within a vector field. This concept has various applications in science, particularly in physics and engineering, especially in calculating the work done by a force acting on an object moving along a certain trajectory. This study aims to examine the application of line integrals in vector fields for calculating the work of a force and to analyze the relationship between a particle’s path and the resulting work. The research method employed is a qualitative approach with mathematical analytical study through theoretical review and calculation of line integrals in two-dimensional vector fields. The analysis process involves defining the vector field function representing the force, parameterizing the particle’s path, and evaluating the line integral to obtain the resulting work. The results show that the work done by a force can be determined through the evaluation of a line integral along the path taken by the particle. Furthermore, the analysis of the vector field indicates that the field is conservative, meaning that the work depends only on the initial and final points of the displacement, not on the shape of the path taken. The visualization of the vector field, particle trajectory graphs, and calculation tables helps provide a clearer understanding of the application of line integrals in analyzing work. Therefore, the concept of line integrals in vector fields can be used as an effective mathematical approach to explain the relationship between force and displacement in a physical system.
