FAKTOR PENYEBAB KESALAHAN SISWA SMK DALAM MENYELESAIKAN SOAL CERITA PADA MATERI PELUANG

It is not easy for students to understand the questions in the form of stories so that errors often occur in the process of solving problems. This study aims to describe the factors that cause vocational students' errors in solving story problems based on Anne Newman. This research is a qualitative research. The instrument used in this research is a test which consists of 3 questions and an interview guide. The subjects in this study were students of class XII TKJ SMK Patria Gadingrejo. Analysis of the data using the analysis of the location of student errors based on Anne Newman's procedure, namely a) reading the problem, understanding the problem, b) transforming the problem, c) process skills, and d) writing the final answer. The factors that cause student errors at each stage are: 1) misunderstood the problem, the cause of which is the lack of understanding and thoroughness of students; 2) problem transformation errors, the reason is that students do not master the concept and do not have mastery of the material; 3) process skill errors, the cause of which students are wrong in doing the initial steps of work; 4) errors in writing the final answer, the reason is that students are not accustomed to writing conclusions.

The ANALISIS KESALAHAN SISWA DALAM MENYELESAIKAN SOAL CERITA SPLDV BERDASARKAN TAHAPAN NEWMAN DITINJAU DARI TIPE KEPRIBADIAN FLORENCE LITTAUER

The aim of this qualitative research is to describe the types of student errors in solving the two-variable linear equation system story problem based on Newman's error analysis in terms of Florence Littauer's personality type. The data sources consisted of 8 students of grade IX C SMP Nuris Jember who had been taught the material of two-variable linear equation systems. The data taken were the results of the questionnaire used to group students into four categories of personality types, the results of the student's story problem solving test results, and the results of the interviews of the students who were the research subjects. The results showed that in solving the two-variable linear equation system material story problems, students sanguinis experienced reading errors, comprehensior errors, transformation errors, process skill errors, and encoding error. Melancholy and phlegmatis students experience transformation error, process skill error, and encoding error. Koleris students experienced process skill error and encoding error.

Students’ Error on Proof of The Group with “Satisfy Axioms Proof” based on Newman Error Analysis

This study aims to analyze students’ errors in solving proof problems on group theory, focus on proofs with satisfying axioms proof. The analysis used refers to the Newman Error Analysis, namely: reading, understanding, transformation, process skills, and coding. The participants in this study consisted of students at the Mathematics Department that enrolled in the group theory course during the odd semester of the 2021/2022 academic year in Universitas Negeri Makassar. Research data was obtained through tests, followed by interviews based on student answers from the test. Based on the results of the error analysis conducted in this study, it can be concluded that: (1) There were no reading errors; (2) Comprehension error was incorrectly write down the meaning of what is known from the problem in symbolic form; (3) Transformation error was error determining the type of proof, mistake write down a formula to show an axiom in the group; (4) Process skill error was an error using arithmetic operations for the validity of an axiom; and (5) Encoding error was an error in writing the final answer, wrong evaluation to conclude.
