Abstract

Kemampuan representasi matematis penting dimiliki siswa. Penelitian ini bertujuan mendeskripsikan kemampuan representasi matematis siswa SMP berdasarkan self-efficacy dengan dimensi generality, level dan strenght. Subjek penelitian kualitatif deskriptif ini terdiri dari tiga orang siswa kelas VII di Desa Cibunar. Data dikumpulkan melalui observasi, tes, dan wawancara. Data dianalisis dengan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa representasi matematis pada siswa yang memenuhi ketiga dimensi self-efficacy belum mampu memenuhi indikator membuat model matematis dari permasalahan yang diberikan dan menyajikan kembali data atau informasi representasi ke representasi diagram, grafik, atau tabel. Dua siswa yang memenuhi dua dimensi self-efficacy sama-sama hanya mampu mencapai satu indikator kemampuan representasi matematis yaitu menggunakan diagram sebagai fasilitas penyelesaiannya. Hal ini menunjukkan self-efficacy berpengaruh pada kemampuan representasi matematis. The ability to mathematical representation is important for students to have. This study aims to describe the mathematical representation ability of junior high school students based on self-efficacy on the dimensions of generality, level, and strength. This study uses a descriptive qualitative approach with the subject of three seventh-grade students in Cibunar Village. Data were collected through observation, tests, and interviews. The data were analyzed in the stages of data reduction, data presentation, and concluding. The results showed that the mathematical representation ability of students who met the three dimensions of self-efficacy had not been able to meet the indicators of making mathematical models of the problems given and presenting data or information representations to diagrams, graphs, or table representations. Two students who meet the two dimensions of self-efficacy are both only able to achieve one indicator of mathematical representation ability, namely using diagrams as a solution facility. This shows that self-efficacy affects the ability of mathematical representation.

Abstract

Penelitian ini bertujuan menganalisis hubungan antara kemampuan pemecahan masalah matematis dengan dimensi self-efficacy (generalisasi, level, dan kekuatan) pada siswa Sekolah Menengah Atas (SMA) dalam Problem Based Learning (PBL) yang terintegrasi dengan prinsip Understanding by Design (UbD). Pengambilan sampel dilakukan melalui teknik purposive sampling sehingga menghasikan tiga siswa kelas XI. Pengumpulan data dilakukan melalui observasi, tes pemecahan masalah matematis, dan wawancara mendalam. Analisis data menggunakan teknik reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa siswa yang menunjukkan penguasaan ketiga dimensi self efficacy tidak berhasil mencapai tahap pemeriksaan ulang dalam proses pemecahan masalah. Siswa yang menguasai dua dimensi gagal menyelesaikan tahap perencanaan dan pemeriksaan ulang, sedangkan siswa yang hanya menguasai satu dimensi berhasil mencapai tahap pemahaman masalah saja. Temuan ini mengungkap kondisi kemampuan pemecahan masalah matematika yang dipengaruhi oleh tingkat self efficacy siswa.

Abstract

This community service program aims to assist mathematics teachers in designing differentiated instruction based on contextual learning. The background of this activity is the need to enhance teachers’ capacity in developing learning strategies that accommodate differences in students’ abilities, interests, and learning styles, so that the learning process becomes more inclusive and meaningful. The method used is descriptive, consisting of training, discussions, and mentoring in lesson design practices. This program emphasizes the application of differentiation principles in the context of mathematics learning that is relevant to everyday life. The results show that teachers gained a better understanding of differentiated instruction and were able to integrate contextual approaches into their lesson designs. Thus, this program is expected to strengthen teachers’ competencies in creating adaptive and relevant learning experiences that support 21st-century skills development.
