Abstract

ABSTRACT This activity aims to equip prospective mathematics teacher students with skills in creating and developing manipulative media, which is a type of learning media that can be used to facilitate the learning process in the classroom. The method used in this activity consists of three stages, namely needs analysis, design, and mentoring in the creation of manipulative media. The results of the activity show that prospective mathematics teacher students are able to understand the need for manipulative media in schools. In addition, they are also able to create and develop interesting mathematical manipulative media for each learning material. The evaluation of the activity shows an increase in the creativity of prospective mathematics teacher students in developing manipulative media for learning in schools. Based on these results, it can be concluded that mentoring in the creation of mathematical manipulative media can explore the potential of prospective mathematics teacher students and encourage them to express their creativity in designing manipulative media that can concretize abstract concepts so that they are more easily understood by students. Keywords: mentoring, manipulative media, prospective teachers ABSTRAK Kegiatan ini bertujuan untuk membekali mahasiswa calon guru matematika dengan keterampilan dalam membuat dan mengembangkan media manipulatif, yang merupakan salah satu jenis media pembelajaran yang dapat digunakan untuk memfasilitasi proses pembelajaran di kelas. Metode yang digunakan dalam kegiatan ini terdiri atas tiga tahap, yaitu analisis kebutuhan, perancangan, dan pendampingan pembuatan media manipulatif. Hasil kegiatan menunjukkan bahwa mahasiswa calon guru matematika mampu memahami kebutuhan media manipulatif di sekolah. Selain itu, mereka juga mampu menciptakan dan mengembangkan media manipulatif matematika yang menarik untuk setiap materi pembelajaran. Evaluasi kegiatan menunjukkan adanya peningkatan kreativitas mahasiswa calon guru matematika dalam mengembangkan media manipulatif untuk pembelajaran di sekolah. Berdasarkan hasil tersebut, dapat disimpulkan bahwa pendampingan dalam pembuatan media manipulatif matematika mampu menggali potensi mahasiswa calon guru serta mendorong mereka untuk mengekspresikan kreativitas dalam merancang media manipulatif yang dapat mengonkretkan konsep abstrak sehingga lebih mudah dipahami oleh peserta didik.   Keywords :pendampingan, media manipulative, calon guru

Abstract

This study aims to analyze the difficulties of junior high school students in solving mathematics problems on the Pythagorean Theorem material in terms of numerical ability based on the limitations of specific studies on numerical barriers affecting students' accuracy in applying the Pythagorean concept. The approach used is qualitative with a case study method. The research subjects consisted of 24 ninth-grade students at an Islamic junior high school in East Karawang, selected through purposive sampling based on the subject teacher's recommendations regarding learning barrier characteristics. The instruments used were a numerical ability test, Pythagorean Theorem questions, and interview guidelines. The results showed that the majority of students had low numerical ability and experienced difficulties in various indicators, such as performing calculations, thinking logically, problem solving, and recognizing number patterns. Even students with high numerical ability still had difficulty determining the slant side in Pythagorean problems. These findings indicate the importance of considering numerical ability in the learning process to develop more targeted and personalized learning methods.
