Abstract

The purpose of this research is to describe the types of mistakes made by students in solving problems based on Newman's theory on statistical material. The type of research used is descriptive research with a quantitative approach. The subjects of this study consisted of 9 Level 1 Mathematics Education students at Suryakancana University. The data collection technique in this study was a written test, with a test instrument consisting of 3 statistical questions in the form of descriptions. The percentage of types of errors made by students at the stage of reading the problem was found to be 20%, comprehension the problem was 20%, transformation was 20%, processing skills was 20%, and encoding was 20%. The types of errors in this study were analyzed using Newman's theory, namely 1) Errors in Reading Problems, 2) Errors in Understanding Problems, 3) Errors in Transformation, 4) Errors in Process Skills, and 5) Errors in Writing Final Answers. Of the 9 students it was found that the most common types of mistakes made by students in solving statistical problems were errors at the stage of understanding the problem and encoding errors.

Abstract

This study aims to comprehensively examine the quality of mathematics learning interest instruments in terms of validity, reliability, undimensionality, distribution of abilities, and suitability of student responses. So, this research uses a survey-based quantitative descriptive method. Data collection was done by distributing a learning interest questionnaire consisting of 25 statements to mathematics education students who were in the 4th semester at one of the universities in Semarang. The results showed that the learning interest instrument used was valid and reliable so that the instrument could be used to measure student learning interest. The distribution of the items also shows that most students admit to having a high interest in learning statistics courses. Analysis of the suitability of student responses shows that 21 statements describe the suitability between learning interests and responses given by students. Meanwhile, 4 other statements showed discrepancies.
