Abstract

The purpose of this study was to describe the types of student errors based on Newman's theory in terms of abstract sequential thinking style in solving logarithmic problems in class X students and to describe the causes of student errors in answering questions based on Newman's theory. This type of research is descriptive qualitative research. In this study, the determination of the subject used a purposive sampling technique. The data collection instrument used a written test sheet, thinking style questionnaire and interviews. Data analysis in this study includes data reduction, data presentation and conclusion drawing. The results showed that there were 4 errors made by abstract sequential students in solving logarithmic problems based on Newman's theory, namely: 1) misunderstanding the problem, the cause of the misunderstanding was that students did not fully understand the problem, and felt rushed because they wanted to quickly solve the given problem. 2) transformation errors, the cause of transformation errors is that students fail to understand the problem so that students are confused when solving problems, and students cannot determine the formula that must be used to solve the problem. 3) process skill errors, the cause of process skill errors is that students are in a hurry and are not careful in doing calculations and 4) mistakes in writing the final answer, the cause of writing the final answer is because the subject is not careful in solving questions, and it is not usually students to re-check answers which he has obtained.
