Abstract

The research aims to identify the types of mistakes students make in solving math problems in straight-line equation materials based on Newman type. The study subjects were 34 students of Grade VIII G SMP Negeri 2 Baturraden. Data retrieval techniques using tests. The data is analyzed with the Newman stage. The results showed 1) the highest percentage of errors on question number two was 93.08%; 2) the highest percentage of student errors at the encoding stage of 69.16%; and the lowest at the Transformation stage of 53.36%; 3) some of the mistakes made include: errors in understanding the problem, inaccuracies placing symbols in the problem-solving process, do not write down the complete information on the question; do not use formulas correctly, do not use proper calculation procedures, and did not write the final result correctly because students were still mistaken in doing calculations.

Analysis of Students’ Errors in Solving Problems in Class XII IPA SMA Negeri 5 Soppeng

“…Many students have not been meticulous in doing calculations, some students still can not use the existing formula to solve the problem. Student mistakes include errors in reading the intent of the question, procedural errors, and careless errors [23].…”

Analisis Kekeliruan Dalam Menyelesaikan Soal Transformasi Ditinjau Dari Kemampuan Awal Matematika

“…Hal ini didukung berdasarkan data hasil wawancara bahwa subjek (R) memang belum sepenuhnya memahami proses yang dicantumkannya. Subekti & Sari (2021) menyatakan bahwa kemampuan peserta didik dalam memahami maksud soal akan menentukan kelancaran proses pengerjaan soal. Hal ini selaras dengan pendapat Maulani & Setiawan (2021) yang mengatakan penyebab peserta didik keliru dalam pengoperasian karena tidak lancar atau teliti dalam mengoperasi.…”
