Abstract

Proses dalam pembelajaran matematika di tingkat SD, SMP dan SMA perlu diadakannya evaluasi dalam menilai kualitas pembelajaran, salah satunya menentukan kemampuan siswa dalam menyelesaikan soal matematika yang diberikan guru. Ditemukan masih banyaknya siswa yang melakukan kesalahan dalam menyelesaikan soal matematika pada beberapa sekolah yang salah satunya peneliti temukan di MTs Al Muhajirin Tapung. Jenis penelitian yang digunakan adalah penelitian kualitataif dengan metode deskriptif. Tujuan dari penelitian ini adalah mengetahui kesalahan siswa dalam mengerjakan soal matematika materi balok menggunakan teori Newman Error pada siswa kelas VIIIA di MTs Al Muhajirin Kecamatan Tapung pada semester genap tahun pelajaran 2020/2021. Teknik pengumpulan data yang digunakan adalah teknik tes yang terdiri dari 4 soal uraian dan non tes yaitu dokumentasi. Analisis data yang peneliti gunakan yaitu pengolahan data, penganalisisan data dan penafsiran data. Dari analisis data didapat hasil bahwa kesalahan siswa paling banyak terjadi pada soal nomor 3 dan untuk jenis kesalahan dari 5 tahapan Newman paling banyak terjadi pada tahap akhir atau encoding error

The study was conducted to determine the students’ mathematical communication skills in the set material. In doing math problems, there are still many students who make mistakes in solving the questions given by the teacher. Students' difficulty in answering questions, one of which is influenced by mathematical communication skills. The method used is descriptive qualitative, which is analyzed from the instrument in the form of 5 written test questions in the form of description questions. The subjects studied were 22 students. This research was conducted on Thursday, October 21st 2021, at Madrasah Tsanawiyah Al Muhajrin Tapung, 2021/2022, totalling 13 female and nine male students. In this study, there are three indicators used, namely 1) mathematical expressions, which are everyday events that are expressed in mathematical concepts and mathematical symbols, 2) drawing, which is mathematical ideas that can be expressed in terms of mathematical concepts. In the form of pictures, and 3) writing (written text) that can show and explain everyday events into mathematical models and mathematical language. From the results of mathematical communication skills based on gender with these three indicators, female students have higher mathematical communication skills than male students. The average percentage for female students is 70.8%, and the percentage of male students is 52.75%. The results of the conversion of scores in the very low category for male students and medium category for female students.
