Abstract

Penelitian ini dilatarbelakangi oleh pentingnya mengembangkan kemampuan mengajukan masalah, dan meningkatkan kualitas pembelajaran melalui pemanfaatan aplikasi geogebra. Tujuan dari penelitian adalah untuk mengetahui apakah kemampuan mengajukan masalah siswa yang menggunakan media pembelajaran berbasis geogebra lebih baik dibandingkan yang berbasis power point, ditinjau (a) secara umum, dan (b) setiap indikator kemampuan mengajukan masalah. Penelitian ini menggunakan penelitian kuantitatif dengan metode komparatif. Sampel dipilih secara acak kelas, yaitu siswa kelas VIII J sebanyak 31 siswa yang pembelajarannya menggunakan media berbasis power point, dan VIII K sebanyak 32 siswa berbasis geogebra Analisis data menggunakan uji parametrik untuk membandingkan kemampuan pengajuan masalah. Hasil penelitian ini adalah kemampuan mengajukan masalah matematik siswa yang menggunakan media pembelajaran berbasis geogebra lebih baik dibandingkan dengan berbasis power point, ditinjau secara umum, dan setiap indikator kemampuan mengajukan masalah. Simpulan dari penelitian ini adalah penggunaan media pembelajaran berbasis geogebra dapat meningkatkan kemampuan mengajukan masalah. This research is motivated by the importance of developing problem posing abilities and improving the quality of learning through the utilization of GeoGebra applications. The aim of the research is to determine whether the problem posing abilities of students who use GeoGebra-based learning media are better compared to those based on PowerPoint, both (a) in general, and (b) for each problem posing ability indicator. This research employs quantitative research with a comparative method. Samples were randomly selected classes, namely class VIII J consisting of 31 students whose learning used PowerPoint-based media, and class VIII K consisting of 32 students using GeoGebra-based media. Data analysis used parametric tests to compare problem posing abilities. The results of this research indicate that the mathematical problem posing abilities of students using GeoGebra-based learning media are better compared to those based on PowerPoint, both (a) in general, and (b) for each problem posing ability indicator. The conclusion drawn from this research is that the use of GeoGebra-based learning media can enhance problem posing abilities.

Abstract

Kemampuan berpikir kreatif matematis peserta didik di Indonesia masih tergolong rendah. Penyebab hal tersebut diantaranya penggunaan model pembelajaran dan media pembelajaran yang kurang mendorong tumbuhnya kemampuan berpikir kreatif matematis peserta didik, sehingga dibutuhkan pemilihan model dan media pembelajaran inovatif yang dapat menumbuhkan kemampuan berpikir kreatif matematis. Salah satunya adalah penggunaan model pembelajaran Creative Problem Solving (CPS) dan media pembelajaran software GeoGebra. Tujuan dari penelitian ini adalah untuk mengetahui bagaimana peningkatan kemampuan berpikir kreatif matematis peserta didik yang pembelajarannya menggunakan model pembelajaran CPS dengan media GeoGebra dan model pembelajaran CPS dengan media PowerPoint. Selain itu, pada penelitian ini dikaji bagaimana perbedaan peningkatan kemampuan berpikir kreatif matematis kedua kelompok tersebut. Pada penggunaan media software GeoGebra diobservasi bagaimana respon peserta didik setelah penggunaan GeoGebra selama kegiatan pembelajaran. Hasil dari uji gain, uji-t dan uji mann-whitney dapat disimpulan penggunaan model CPS berbantuan GeoGebra dapat meningkatkan kemampuan berpikir kreatif. Sebagian besar respon peserta didik setelah penggunaan GeoGebra selama kegiatan pembelajaran adalah sangat baik. Students' mathematical creative thinking skills in Indonesia are still considered low. This is partly caused by the use of learning models and media that do not sufficiently encourage the growth of these skills; therefore, it is necessary to select innovative learning models and media that can foster mathematical creative thinking. One such approach is the use of the Creative Problem Solving (CPS) model and GeoGebra software. The purpose of this research is to determine the improvement of students' mathematical creative thinking skills through the implementation of the Creative Problem Solving (CPS) model assisted by GeoGebra compared to the CPS model assisted by PowerPoint. Furthermore, this study examines the difference in the improvement of creative thinking skills between the two groups. Regarding the use of GeoGebra, students' responses were observed after its implementation in learning activities. Based on the results of the N-gain test, t-test, and Mann-Whitney test, it can be concluded that the use of the CPS model assisted by GeoGebra can improve creative thinking skills. Moreover, the majority of students' responses toward the use of GeoGebra during learning activities were very good.
