Abstract

Using Newman's Error Analysis (NEA) as a framework, this study will examine the many ways in which MAN 3 Medan students blunder while answering problems involving logarithms and exponentials. A total of thirty-one MIPA class X students served as subjects for this qualitative descriptive study. Essay tests, interviews with math instructors, and records of student work all contributed to the data set. Data analysis involves reducing, presenting, and making conclusions while triangulating sources to ensure the data is legitimate. According to the research, the two most common points of mistake are when people are trying to grasp the issue and when they are trying to convert it. This is because pupils have a hard time grasping the characteristics and fundamental ideas of logarithms and have a habit of rote memorization rather than critical thinking. Other factors that also affect include the lack of utilization of learning media and low student learning motivation. After being given discussion-based learning and interactive media, the post-test results showed an increase in comprehension and a decrease in conceptual errors. This research recommends that teachers should emphasize student-centered learning by strengthening basic concepts and implementing contextual problem-solving strategies.

Abstract

This study aims to analyze the types of student errors in solving problems on determining the size of angles in flat shapes. The subjects of the study were students of the Mathematics Education Study Program, State University of Medan, academic year 2024/2025. Data were obtained through written tests and interviews with 10 students. The results of the study showed that the errors often made by students included conceptual errors (42%), procedural errors (38%), and computational errors (20%). Conceptual errors are mainly related to understanding the relationship between angles in triangles and supplementary angles, procedural errors are related to unsystematic solution steps, while computational errors are errors in making calculations. This study provides recommendations to improve students' conceptual understanding of angles and their relationships in flat shapes.
