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

The usefulness of mathematics in the 21st century is increasingly felt by society. Therefore, mathematics is increasingly needed by everyone and by society as a whole. In the current industrial era 4.0, there is interaction between humans and machines, especially computers. One computer application that can be used in mathematical problems is GeoGebra. GeoGebra is dynamic software for mathematics, contains interconnected Geometry and Algebra features, and is very helpful in understanding and facilitating the teaching and learning process of mathematics. The aim of this research is to find out how mathematics teachers perceive the use of GeoGebra-based learning media in mathematics learning. The research method is descriptive qualitative. The research population was all teachers from an educational foundation in Pamengpeuk District, Garut Regency, participants in a workshop on the use of GeoGebra-based learning media in mathematics learning. This workshop activity is a community service activity. The results of this research conclude that community service activities through workshops on the use of GeoGebra-based learning media in mathematics learning are effective in increasing teachers' insight and motivation to use the GeoGebra application in mathematics learning.

Abstract

This training was conducted to improve teacher competence, especially in the aspect of deepening the Calculus material. This training provides ways to solve mathematical problems related to Calculus which are not usually given at the secondary school level. The training materials cover Inequality, Drawing Functions Graphs, and Sure Integrals. Based on the results of filling out the training evaluation questionnaire, the teachers gave a positive response and were satisfied because they got more knowledge and insight about the concept of solving Calculus problems that are not usually given at the high school level. It is expected that the teachers can apply the knowledge that has been obtained for the development of learning in the classroom and be able to facilitate students to gain knowledge and have comprehensive mathematical abilities.

Abstract

Rendahnya literasi di Indonesia berdasarkan data PISA dan UNESCO melatarbelakangi penelitian ini untuk mengkaji pengaruh program kunjungan perpustakaan terhadap minat baca siswa Sekolah Dasar Negeri (SDN) Bangka 3 Bogor. Tujuan penelitian adalah untuk mengevaluasi efektivitas program tersebut dalam meningkatkan budaya baca siswa. Menggunakan metode kuantitatif dengan teknik pengumpulan data melalui angket dan observasi, studi ini melibatkan 151 siswa sebagai responden. Temuan penelitian menunjukkan rata-rata skor minat baca siswa mencapai 85 dari skala 100, yang diklasifikasikan dalam kategori "Sangat Tinggi". Meskipun kunjungan perpustakaan terbukti efektif meningkatkan minat baca di sekolah, hasil observasi mengungkap rendahnya motivasi siswa untuk meminjam buku secara mandiri untuk dibawa pulang. Disimpulkan bahwa program kunjungan berhasil membangun antusiasme membaca di tempat, namun belum optimal dalam membentuk kebiasaan membaca berkelanjutan. Implikasi penelitian ini menekankan perlunya sekolah mengembangkan strategi tambahan, seperti program penghargaan peminjaman buku dan keterlibatan orang tua, guna memperluas budaya literasi dari lingkungan sekolah ke lingkungan rumah.

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.
