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.
