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

The teacher's ignorance of the publication of journal articles became the starting point for the problems to be solved so it became the theme raised in this training. The solution provided through this training is material and guidance from the presenters to all participants. The purpose of this training activity is to provide information about articles and journals, as well as the process of submitting articles to accredited national journals, as well as the scope of it to MTs teachers in Garut Regency in particular, and generally to all other participants. The training method used has five stages, including introduction, socialization, training, practice, and monitoring. The subjects of this training are all teachers who are collected in the MGMP MTs Garut Regency, as well as other participants who work as teachers, lecturers, or students on a national scale. The training activities were carried out in two sessions, including material presentation and practical skills. The results of the evaluation form regarding this training activity were very good, all questions received positive responses and answers from all participants. It seems that several teachers have committed to follow up this training activity by trying to write their findings in the form of articles and publish them in the designated accredited national journals. This training concludes that the insights and knowledge conveyed by the presenters in this training activity can open the eyes of all teachers to aspects of scientific publications that so far have never even been glimpsed by teachers.

Abstract

Although the implementation of the National Assessment policy has been running for one year, it is suspected that the understanding of teachers, parents and students about the National Assessment is not sufficient. The results of the situation analysis on the understanding of teachers at PLB teachers Kab Garut regarding minimum competency assessments show that (1) teachers' understanding of AN is still low and (2) the ability of teachers to prepare problem solving-based questions is still low. The solution agreed upon with partners is to optimize learning by training and assisting teachers in developing problem solving questions. The target audience is 16 teachers at Guru PLB Kab Garut. The method of implementing the activity is the participatory rural appraisal model, the technology transfer model, and training. The results of the activity show that there has been an increase in teachers' understanding of the problem solving questions with an average score of 76. A total of 62.5% of the training teachers have also succeeded in developing their own problem solving questions in accordance with the guidelines.

Abstract

This study investigates the role of interactive multimedia in differentiated learning to enhance students’ comprehension, mathematical representation, and self-confidence, while accounting for their diverse learning styles. The research involved 97 eighth-grade students at a public junior high school at Garut Regency, Indonesia, divided into four classes. A quantitative approach with a quasi-experimental design was employed, grouping students homogeneously and heterogeneously based on visual, auditory, and kinesthetic learning styles. Data were collected using mathematical comprehension and representation tests, as well as a self-confidence questionnaire. The results show improvements in mathematical comprehension by 17.59 points in homogeneous group and 16.86 points in heterogeneous group, and increases in representation ability by 13.08 and 12.41 points, respectively. Students’ self-confidence also increased in both groups, with a difference of 0.169 points. These findings indicate that interactive multimedia integrated into differentiated learning significantly enhances students’ cognitive and affective outcomes. In conclusion, multimedia aligned with students’ learning styles fosters an inclusive and adaptive learning environment, supports differentiated instruction, and strengthens students’ conceptual understanding and confidence.

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.
