Abstract

Because students were having trouble picturing the three-dimensional system of coordinates in a spatial analysis geometry course, their mathematical problem-solving abilities were still low. Educational movies that aid in visualization are essential for pupils. The study at hand used a design consisting of a pretest-posttest control group and was quasi-experimental in nature. While the control class experienced conventional teaching, the learners in the experimental group learned using three-dimensional coordinate system audiovisual media. A test of one's capacity to solve mathematical problems was used, along with observation sheets and interviews. A total of thirty-four participants made up the sample for this study, which was carried out at the University of Pattimura's Mathematics Education Study Program. Evaluation was of t-testing outcomes on mathematical problem-solving skills. The findings demonstrated that students' proficiency in solving problems with mathematics increased when they were taught to use a video about the three-dimensional coordinate system.

Abstract

Penelitian ini bertujuan untuk mengetahui ada tidaknya perbedaan hasil belajar siswa yang diajarkan dengan model pembelajaran Kooperatif Tipe Student Team Achievement Division (STAD) dan model pembelajaran Problem Based Learning (PBL) di kelas VII SMP Negeri 37 Maluku Tengah. Populasi dalam penelitian ini adalah semua siswa kelas VII SMP Negeri 37 Maluku Tengah Tahun Pelajaran 2023/2024. Pemilihan sampel dilakukan dengan teknik sampling jenuh. Sehingga yang menjadi sampel dalam penelitian ini adalah semua anggota populasi yang terdiri dari 2 kelas, yaitu kelas VII-1 dan kelas VII-2 dengan jumlah 42 siswa. Perbedaan hasil belajar siswa bisa dilihat dari hasil analisis deskriptif data diperoleh rata-rata hasil belajar siswa yang diajarkan dengan model STAD adalah 54,15. Sedangkan rata- rata hasil belajar siswa yang diajarkan dengan model PBL adalah 62,84. Kemudian nilai tersebut dibandingkan dengan nilai hasil dari uji Mann-Withney pada taraf signifikansi 5% diperoleh Asymp.Sig. < α yakni 0,043 < 0,05, maka diperoleh kesimpulan bahwa terdapat perbedaan yang signifikan antara rata- rata hasil belajar siswa yang diajarkan dengan model STAD dan model PBL pada materi operasi hitung bentuk aljabar.

Abstract

Learning Videos are one of the effective learning media in supporting the teaching and learning process during the COVID-19 Pandemic. With the help of the geogebra application and pen tablet tools made in the form of learning videos, it is very helpful for students to understand abstract concepts to be visually clear. (This research is a study with a pretestt-postestt non equivalent control group design. The experimental class was treated with a learning video made with the help of the geogebra application and pen tablet while the control class learned using powerpoint. The results obtained by the value of Sign. (2-tailed) testing of the N-Gain score is 0.00 less than a so that H0 is rejected, meaning that the improvement in the learning outcomes of experimental class students is better than control class students, meaning that there is a difference in the improvement of student learning outcomes on spherical material in the analytical geometry course of significant space

Abstract

This study aims to find out: (1) the learning outcomes of students taught using the discovery learning model on statistical material for grade VIII students of SMP Negeri 20 Ambon; (2) student learning outcomes taught using problem solving learning models on statistical material for grade VIII students of SMP Negeri 20 Ambon; (3) differences in student learning outcomes taught using the discovery learning model and the problem solving learning model in statistical material for grade VIII students of SMP Negeri 20 Ambon. The type of research used is Quasi Experimental with a Nonequivalent Control Group design. The population in this study was all grade VIII students of SMP Negeri 20 Ambon, totaling 44 students using saturated sampling techniques, 22 students from class VIII-1 and 22 students from class VIII-2 were taken to be sampled. The instrument used in this study is a test question. The results showed that there were differences in the learning outcomes of grade VIII students of SMP Negeri 20 Ambon who were taught using the discovery learning learning model and the problem solving learning model on statistical material. This can be seen from the results of the t-test, namely the sig of value. (2-tailed) = 0.013 < α= 0.05 so that accepted and rejected.

Abstract

Pemahaman konsep dalam pembelajaran matematika menjadi salah satu bagian penting yang harus dimiliki oleh setiap siswa. Namun, nyatanya masih terdapat siswa yang kesulitan dalam memahami suatu konsep. Salah satu alat sederhana yang dapat digunakan untuk mengukur dan menentukan sejauh mana level pemahaman konsep siswa dalam proses pembelajaran yaitu taksonomi SOLO. Penelitian ini bertujuan untuk mendeskripsikan pemahaman konsep siswa berdasarkan taksonomi SOLO pada materi bilang pecahan kelas VII SMP Negeri 6 Ambon. Jenis penelitian yang digunakan dalam penelitian ini, yaitu penelitian deskriptif kualitatif yang didukung dengan data kuantitatif. Hasil penelitian menunjukan bahwa pemahaman konsep siswa dengan kategori subjek tinggi berada pada level extended abstract. kategori subjek sedang berada pada level multistructural, sedangkan kategori subjek rendah berada pada level prestructural
