Analisis Kesalahan dalam Menyelesaikan Soal Barisan dan Limit Barisan Berdasarkan Prosedur Newman: Studi Kasus Mahasiswa Prodi Pendidikan Matematika

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%.
