Abstract

Education for a child is very important for motor development and his thinking becomes critical in responding to an incident. His skills can be honed properly and master skills that support his future career. So that the potential for the progress of each child can be achieved and learning objectives can be completed optimally. In life, of course, you will not be separated from various kinds of problems, so the solution to every problem must exist and be able to solve it. The problem based learning strategy is the answer to improve problem solving skills. This strategy is a problem-triggered learning model, which encourages students to learn and work cooperatively in groups to find solutions, think critically and analytically, be able to determine and use appropriate learning resources. For this reason, it is necessary to apply this method in education. The purpose of this research was to improve problem solving skills using the problem based learning (PBL) method. By maximizing this method many positive impacts will be obtained. The method used in this research is a quantitative method. The data obtained is through the distribution of a questionnaire. The questionnaire was made using the Google form application. The results of this study explain that the use of problem based learning strategies to improve problem solving skills in education can help students solve problems with the right solutions. As well as sharpening the ability to think critically and systematically, so that they can be more mature in responding to various problems. The conclusion of this study is that the use of problem-based learning strategies to improve problem-solving skills by students can be maximized, because they have mastered the right and effective way to solve a problem. The limitation of this research is that researchers only conduct this research at the school level where the method requires new strategies in learning such as the use of problem based learning strategies.

Abstract

This study aims to describe the use of AR: GeoGebra 3D Calculator in improving students' understanding of mathematical concepts in three-dimensional materials. This study uses a quantitative approach with a pseudo-experimental method. The sample consisted of 69 eleventh grade students from MAS Al-Washliyah 22, which was divided into an experimental group (35 students) using AR: GeoGebra 3D Calculator and a control group (34 students) using conventional methods. The data collection technique is carried out through a concept comprehension test, namely pretest and posttest. Data analysis was carried out quantitatively on the test results obtained using an independent t-test test for normalized gain. The results showed that the experimental group showed a significantly higher increase in average scores from pretest to postes compared to the control group. The results of the independent t-test of the postes scores showed that there was a significant difference between the two groups. The normalized gain analysis further confirmed that the experimental group achieved a higher improvement (0.61) than the control group (0.41), with a significant difference (t = 4.876, p <0.001). The results of this study show that the use of AR: GeoGebra 3D Calculator significantly improves students' understanding of concepts in three-dimensional materials compared to conventional methods

Abstract

Matematika merupakan salah satu pelajaran yang kurang disukai siswa karena dianggap sulit dan membosankan. Oleh sebab itu diperlukan aplikasi pembelajaran agar pembelajaran menjadi menyenangkan seperti aplikasi kalkulator grafik. Pada kalkulator grafik, siswa diberi kebebasan untuk mencoba berbagai pertidaksamaan garis, mengamati berbagai bentuk garis, arah arsiran sesuai dengan bentuk pertidaksamaan, dan titik potong yang terbentuk dari dua garis atau lebih. Melalui aplikasi ini, siswa akan lebih mudah memahami materi program linear dan tidak merasa bosan belajar di kelas. Metode yang digunakan dalam pengabdian masyarakat ini adalah metode pendampingan dan praktik langsung. Setelah dilaksanakan pelatihan, 85% siswa telah mampu menggunakan aplikasi ini dan hasil angket menyatakan bahwa 95% siswa merasa pelatihan ini sangat bermanfaat. Pelatihan ini memberikan informasi yang baru kepada siswa bahwa belajar matematika tidak sesulit yang mereka bayangkan.
