Abstract

This community service program was carried out with the primary objective of enhancing the professional competence of mathematics teachers at the Madrasah Tsanawiyah (MTs) level in Mataram City, particularly in the teaching of geometry. Recognizing the importance of mastering digital technology in modern mathematics learning, the program focused on the introduction and application of GeoGebra as an interactive medium for teaching geometry concepts. The activities were conducted at the Basic Computer Laboratory of the Faculty of Mathematics and Natural Sciences, Universitas Mataram, involving 18 MTs mathematics teachers. The program consisted of introducing fundamental concepts of geometry, hands-on training on the technical use of GeoGebra, and an evaluation of learning outcomes through pre-tests and post-tests. The evaluation results indicated an improvement in participants’ scores, demonstrating the effectiveness of the training. The teachers’ enthusiasm was evident from their active participation in discussions, asking questions, and exploring GeoGebra’s features during the training. The pre-test results showed that participants scored between 7 and 20, with an average of 13.56. Following the post-test, scores improved significantly, ranging from 20 to 28 with an average of 24.89. This confirms that all teachers, without exception, experienced an increase in scores. The positive impact of this program is expected to contribute to improving the quality of mathematics teaching at the MTs level.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menjawab permasalahan yang dihadapi guru MTs dalam mengajarkan materi geometri dan penerapan pendekatan pemecahan masalah (problem solving). Fokus kegiatan adalah pada pendalaman filosofi dan konsep dasar geometri, serta pelatihan penerapan problem solving dalam pembelajaran. Pada pelatihan penguatan konsep geometri, peserta mendapatkan pemahaman yang lebih mendalam mengenai makna konseptual di balik sifat-sifat bangun datar dan ruang, relasi antar-teorema, serta relevansinya dalam kehidupan sehari-hari. Hasil evaluasi menunjukkan lebih dari 80% peserta mampu memahami filosofi konsep geometri dan mengaitkannya dengan strategi pembelajaran. Sementara itu, melalui pelatihan problem solving, guru dilatih untuk mengenali tahapan pemecahan masalah mulai dari memahami persoalan, merancang strategi, melaksanakan solusi, hingga merefleksi hasil. Sebanyak 70% peserta berhasil menyusun perangkat pembelajaran berbasis problem solving yang aplikatif di kelas. Efektivitas kegiatan ini juga ditunjukkan melalui hasil pre-test dan post-test, di mana seluruh peserta mengalami peningkatan pemahaman, dengan beberapa mencapai peningkatan skor hingga 75 poin. Secara keseluruhan, kegiatan pengabdian ini berhasil meningkatkan pemahaman konseptual guru terhadap geometri, keterampilan pedagogik berbasis problem solving, serta kepercayaan diri dalam mengajar matematika secara lebih bermakna dan kontekstual.

Abstract

Geometry is one of the fundamental topics in mathematics, playing a crucial role in understanding shapes, sizes, positions, and spatial relationships between objects. Mastery of this concept is essential; however, in practice, many students still struggle to grasp geometry material. This issue is also evident at SMA Negeri 1 Pujut, where several students demonstrate a low level of understanding of geometric concepts. In response to this problem, the aim of the research is a community service activity was carried out in the form of tutoring sessions focused on improving students' understanding of geometry. This activity employed a visualization approach through function graph sketches to help students better comprehend the interconnections between concepts in a more concrete way. Based on the evaluation results, data showed that 86.67% of students exhibited improved learning outcomes after participating in the activity. This achievement indicates that the instructional method used by the facilitators was quite effective and well-received by the majority of participants.

Abstract

Mastery of mathematical problem-solving skills based on logical reasoning is an important aspect in supporting students’ success in facing the Computer-Based Written Examination (UTBK). However, many students still encounter difficulties in understanding concepts and effectively solving UTBK-type questions. To address this issue, a community service program was conducted at SMA Negeri 1 Pujut with the aim of enhancing participants’ mathematical reasoning capacity. The activity began with an introduction to the Mathematics study program, followed by training sessions on strengthening concept mastery through logical reasoning and practice in solving UTBK questions, delivered by lecturers and students. The effectiveness of the training was evaluated through a comparison of participants’ pre-test and post-test results. This activity was attended by 30 students as training participants. The evaluation showed a significant improvement in post-test scores, with 83.33% of participants experiencing an increase in their scores, and the majority achieving above 60 in the post-test. These findings indicate that the applied training method was effective in improving students’ conceptual understanding of mathematics and their readiness to face the UTBK.
