Analysis of Students' Errors Based on Kastolan Stages on Sensing and Intuiting Personality

Students' errors in solving math problems, especially on the System of Linear Equations of Two Variables (SPLDV) topic, are an important concern in the learning process. A deep understanding of the types of errors students make, especially in relation to their personality types, can help develop more effective learning strategies. This study aims to analyze students' errors based on Kast Olan stages and Sensing and Intuiting personality types. Using a qualitative case study approach, the research involved 30 high school students who were selected based on the MBTI personality test. The results showed that students with Sensing type had an average error of 83%, with the largest error in the technical aspect (100%), while students with Intuiting type had 100% errors in all categories. Sensing students had difficulty in calculation accuracy while Intuiting students had difficulty understanding concepts and following procedures systematically. These findings suggest that learning strategies need to be tailored to student's personality types, where Sensing students need more practice in technical skills while Intuiting students need a more systematic approach to problem-solving.
