Abstract

Tujuan penelitian ini yaitu untuk menganalisis jenis kesalahan yang dilakukan oleh siswa serta penyebab kesalahan peserta didik dalam menyelesaikan soal fungsi kuadrat menggunakan prosedur Newman di SMAS PAB 8 SAENTIS. Penelitian deskriptif kualitatif ini melibatkan 22 siswa kelas XI di SMAS PAB 8 SAENTIS sebagai subjek penelitian. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, tes tertulis, dan dokumentasi. Teknik analisis data yang digunakan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa besar persentase kesalahan peserta didik dalam menyelesaikan soal cerita fungsi kuadrat sesuai prosedur Newman, ialah sebagai berikut : (a) kesalahan membaca sebesar 5,68%, (b) kesalahan memahami sebesar 23,86%, (c) kesalahan transformasi sebesar 15,9%, (d) kesalahan keterampilan proses sebesar 46,59%, dan (e) kesalahan dalam penulisan jawaban akhir sebesar 52,27%. Dengan mengidentifikasi dan memahami berbagai jenis kesalahan yang terjadi, pendidik dapat merancang strategi pembelajaran yang lebih efektif.

Abstract

The ability to solve mathematical problems is a person's ability to understand problems, construct mathematical models, choose the right strategy, and evaluate the correctness of the solution. This study aims to analyze errors in solving sequence and limit problems of real number sequences in semester VI students using the Newman procedure. This study is a qualitative descriptive study involving 10 students of the Mathematics Education Study Program, State University of Medan, data was collected through tests. The instrument used was real analysis problems with the topic of sequences and limit problems consisting of 4 essay questions. Data collection techniques include written tests. The data analysis techniques used are data reduction, data display, and conclusion drawing. The results of the analysis show that the average student error in solving 4 sequence and limit problems is 5% reading errors, 16.5% understanding errors, 7.5% transforming problems, 11.25% errors in the process skills stage, and 8.75% in writing/notation. The most significant error occurred at the understanding stage, with an average percentage of 16.8%.
