Abstract

Students with low mental disabilities have limitations in intellectual matters and have difficulty in learning the addition and subtraction of integers 1-50. The purpose of this study was to describe the thought process of low mentally disabled students in solving integer and subtraction problems associated with media use that students often encounter through observation. The thought process referred to refers to the Piaget stage indicator, namely the occurrence of disequilibrium, assimilation, or accommodation. This type of research is qualitative descriptive. The subjects in this study were two students with low mental disabilities in class V MI Al Kawtsar Panti Jember, East Java, Indonesia. The stages in this study are 1. giving questions, 2. determining trends according to theory and 3. interviewing. Both subjects cannot understand the sentence in the question and answer the question inconsistently. In addition, the two subjects were only silent when they did not know the purpose of the researchers' questions about understanding the questions. Subjects experience assimilation when the subject can immediately answer questions from the researcher spontaneously regardless of the correct or correct answer. The two subjects also experienced accommodation when they paused for a moment before answering correctly the questions from the researcher. So that the tendency of low mentally disabled students to solve the addition and reduction problems of integers is to experience the three stages of thinking according to Piaget even though that is done with a maximum approach from a researcher.

Abstract

Penelitian ini dilakukan untuk menganalisis kesalahan siswa dan penyebab kesalahan siswa dalam mengerjakan soal cerita bentuk pemecahan masalah segitiga dan segiempat berdasarkan Teori Newman yang terdiri dari membaca, memahami, transformasi, keterampilan proses, dan penulisan. Metode penelitian ini adalah kualitatif,Penelitian ini dilakukan pada 27 siswa kelas VII. Peneliti memberikan tes kepada 27 siswa untuk menentukan apakah ada kesalahan yang dilakukan siswa dalam mengerjakan soal cerita bentuk pemecahan masalah segitiga dan segiempat. Berdasarkan hasil tes yang sudah diperiksa dan dianalisis, peneliti membagi 27 siswa tersebut kedalam 3 kelompok yaitu kelompok siswa dengan kesalahan tinggi (banyak), kelompok siswa dengan kesalahan sedang, dan kelompok siswa dengan kesalahan rendah (sedikit). Dari masing-masing kelompok, dipilih masing-masing 2 siswa untuk di wawancarai untuk mengetahui penyebab kesalahan siswa dan sebagai bahan unuk proses keabsahan data agar data lebih valid. Penelitian ini menghasilkan kesalahan memahami, transformasi, keterampilan proses, dan penulisan pada kelompok kesalahan tinggi (banyak). Kesalahan transformasi, keterampilan proses, dan penulisan pada kelompok kesalahan sedang. Kesalahan transformasi dan keterampilan proses terjadi pada kelompok kesalahan rendah (sedikit).
