Matematika kerap dipersepsikan sebagai mata pelajaran yang sulit karena bersifat abstrak dan kurang terhubung dengan pengalaman nyata siswa. Salah satu upaya untuk mengatasi permasalahan tersebut dilakukan melalui pemanfaatan alat peraga yang mampu memvisualisasikan konsep-konsep matematika, khususnya pada materi geometri. Artikel ini bertujuan untuk mendeskripsikan pelaksanaan kegiatan pendampingan pembuatan alat peraga geometri di MTsN 5 Cirebon dengan menggunakan pendekatan Participatory Action Research (PAR). Kegiatan dilaksanakan pada semester genap tahun ajaran 2024/2025 dan melibatkan 23 guru matematika sebagai peserta sekaligus responden. Proses pendampingan meliputi tiga tahap, yaitu penjelasan dan diskusi mengenai jenis serta fungsi alat peraga, perancangan dan pembuatan alat peraga, serta uji coba penggunaannya dalam pembelajaran di kelas. Hasil kegiatan menunjukkan bahwa sebanyak 11 jenis alat peraga geometri berhasil dirancang, dibuat, dan digunakan. Evaluasi kegiatan dilakukan melalui angket skala Likert yang dianalisis secara deskriptif kuantitatif dengan persentase, mencakup aspek pelaksanaan kegiatan, kualitas alat peraga, dan manfaat penggunaannya. Hasil analisis menunjukkan bahwa aspek pelaksanaan memperoleh skor sebesar 89%, kualitas alat peraga sebesar 87%, dan manfaat penggunaan alat peraga sebesar 88%, yang seluruhnya berada pada kategori sangat baik. Temuan ini menunjukkan bahwa kegiatan pendampingan pembuatan alat peraga pembelajaran matematika pada materi geometri di MTs 5 Cirebon mampu meningkatkan kreativitas dan kemampuan guru matematika dalam merancang, membuat dan menggunakan alat peraga pembelajaran matematika pada materi geometri, serta mendukung terwujudnya pembelajaran matematika yang lebih interaktif, menyenangkan, dan bermakna.

This study aims to describe the forms of mathematical misconceptions of students in solving contextual problems in fractional number material. The research used a descriptive qualitative approach and was carried out at SD Negeri 1 Gandasoli, Kuningan Regency. The subjects of the study were all students of class V totaling 39 people. Data was obtained through a written test in the form of contextual description questions about fractional numbers that have gone through the validity test stage. Based on the test results, students were classified into three levels of mathematical ability, namely high, medium, and low, then 9 students were selected as sample subjects for in-depth analysis. Data analysis is carried out through the stages of data reduction, data presentation, and conclusion drawn. The results of the study show that students still experience various types of mathematical misconceptions, including misconceptions of translation, signs, calculations, systematic, concepts, and strategies. Misconceptions of translation and signs were found at all levels of mathematical ability, while calculating, systematic, and conceptual misconceptions appeared in students of medium and low ability. Strategic misconceptions are only found in students with low mathematical ability. These findings show that the complexity of misconceptions increases as students' mathematical ability levels decrease, so learning that emphasizes understanding concepts and meaningful problem-solving in fractional number material is needed.

AbstrakKegiatan ini bertujuan untuk memberikan pendampingan pembuatan alat peraga inovatif dalam meningkatkan pemahaman matematis siswa pada materi geometri di SLB-C Pancaran Kasih Kota Cirebon. Kegiatan pendampingan dilakukan di SLB-C Pancaran Kasih Kota Cirebon pada semester genap tahun ajaran 2023/2024. Pada kegiatan ini melibatkan kolaborasi antara dosen dan mahasiswa Tadris Matematika UIN Siber Syekh Nurjati Cirebon, serta siswa dan guru-guru matematika di SLB-C Pancaran Kasih Kota Cirebon. Metode yang digunakan dalam kegiatan ini adalah pendekatan penelitian Participatory Action Research (PAR) yang mencakup pemberian pengetahuan tentang macam-macam alat peraga inovatif yang dapat digunakan untuk meningkatkan pemahaman matematis siswa pada materi geometri, bimbingan dalam merancang dan membuat alat peraga inovatif, serta pendampingan implementasi penggunaan alat peraga di kelas, dan evaluasi kegiatan. Hasil pendampingan menunjukkan bahwa pendampingan pembuatan alat peraga inovatif efektif dalam meningkatkan kemampuan guru matematika di SLB-C Pancaran Kasih Kota Cirebon dalam merancang, membuat dan menggunakan alat peraga inovatif pada materi geometri di kelas. Hasil pendampingan juga menunjukkan bahwa kemampuan pemahaman matematis siswa pada materi geometri di SLB-C Pancaran Kasih Kota Cirebon meningkat. Aspek kepuasan siswa terhadap penggunaan alat peraga dalam pembelajaran geometri menunjukkan rata-rata sebesar 76% berada dalam kategori "Puas". Aspek kepuasan siswa terhadap kualitas alat peraga geometri menunjukkan rata-rata sebesar 78% berada dalam kategori "Baik". Aspek kepuasan guru terhadap penggunaan alat peraga dalam pembelajaran geometri menunjukkan rata-rata sebesar 76% berada dalam kategori "Puas". Kata kunci: alat peraga; pemahaman matematis; geometri. AbstractThis activity aims to provide guidance on the creation of innovative teaching aids to improve students' mathematical understanding of geometry at SLB-C Pancaran Kasih in Cirebon City. The guidance activity was conducted at SLB-C Pancaran Kasih in Cirebon City during the second semester of the 2023/2024 academic year. This activity involves collaboration between lecturers and students of the Mathematics Education program at UIN Syekh Nurjati Cirebon, as well as students and mathematics teachers at SLB-C Pancaran Kasih in Cirebon City. The method used in this activity was the Participatory Action Research (PAR) approach, which included providing knowledge about various innovative teaching aids that can be used to enhance students' mathematical understanding of geometry, guidance in designing and creating innovative teaching aids, mentoring the implementation of teaching aids in the classroom, and evaluating the activity. The results of the mentoring showed that the mentoring in creating innovative teaching aids was effective in improving the ability of mathematics teachers at SLB-C Pancaran Kasih in Cirebon City to design, create, and use innovative teaching aids for geometry lessons in the classroom. The results also indicated that students' mathematical understanding of geometry at SLB-C Pancaran Kasih in Cirebon City improved. The aspect of student satisfaction with the use of teaching aids in geometry learning showed an average of 76% in the “Satisfied” category. The aspect of student satisfaction with the quality of geometry teaching aids showed an average of 78% in the ‘Good’ category. The aspect of teacher satisfaction with the use of teaching aids in geometry learning showed an average of 76% in the “Satisfied” category. Keywords: teaching aids; mathematical understanding; geometry.
