Analysis of Student Misconceptions in Working on Algebraic Form Counting Operations Using Certainty of Response Index
Abstract
Abstract: This study aim is to determine the misconceptions that occur in students and the factors that cause students to experience misconceptions in the material of algebraic arithmetic operations. The research which was conducted at SMP Negeri 4 Tasikmalaya class VII C with a total of 32 students was a qualitative research with a descriptive approach. The subjects of this study were taken purposively, namely 5 students of class VII C of SMP Negeri 4 Tasikmalaya. The data collection technique consisted of a misconception analysis test accompanied by the Certainty of Response Index (CRI) and interviews. Data analysis techniques consisted of data reduction, data presentation, and verification. Based on the results of data analysis, it is concluded that (1) S4 misconception of equations, S10 misconception of operations, S17 misconceptions of variables, S28 misconception of fractions, S10 misconceptions of negative signs (2) The causes of misconceptions that occur include incorrect student preconceptions, student associative thinking, humanistic thinking, incomplete reasoning, incorrect intuition, student abilities and student interest in learning.
Keywords: Certainty of response index, misconceptions, algebraic form counting operations.
Abstrak: Penelitian ini bertujuan untuk mengetahui miskonsepsi yang terjadi pada siswa serta faktor penyebab siswa mengalami miskonsepsi pada materi operasi hitung bentuk aljabar. Penelitian yang dilaksanakan di SMP Negeri 4 Tasikmalaya kelas VII C dengan jumlah 32 peserta didik merupakan penelitian kualitatif dengan pendekatan deskriptif. Subjek dari penelitian ini diambil secara purposive yaitu 5 siswa kelas VII C SMP Negeri 4 Tasikmalaya. Teknik pengumpulan data terdiri dari tes analisis miskonsepsi yang disertai dengan Certainty of Response Index (CRI) dan wawancara. Teknik analisis data terdiri dari reduksi data, penyajian data, dan verifikasi. Berdasarkan hasil analisis data diperoleh kesimpulan bahwa (1) S4 melakukan miskonsepsi persamaan, S10 melakukan miskonsepsi operasi, S17 melakukan miskonsepsi variabel, S28 melakukan miskonsepsi pecahan, S10 melakukan miskonsepsi tanda negatif. (2) Penyebab miskonsepsi yang terjadi diantaranya prakonsepsi yang siswa yang salah, pemikiran asosiatif siswa, pemikiran humanistik, penalaran yang tidak lengkap, intuisi yang salah, kemampuan siswa dan minat belajar siswa.
Kata kunci: Certainty of response index, miskonsepsi, operasi hitung bentuk aljabar.
