There were 55.88% reflective cognitive style students, 23.54% impulsive, 11.76% slow-inaccurate, and 8.82% fast-accurate. Reflective students have a misconception rate of 22.10%, with the highest error in symbolic operations. Impulsive students showed a misconception rate of 34.17%, with the highest error in symbolic operations. Reflective students experience process skill errors, while impulsive students often experience transformation errors. These results indicate that students with impulsive cognitive styles rush to solve problems. Students who have a reflective cognitive style, when viewed based on the nature of their cognitive style, on average, show in the classroom that students tend to be slow in solving problems or problems. However, the answers given are more accurate and precise. Abstrak Penelitian ini bertujuan mengidentifikasi dan menganalisis miskonsepsi pada numerasi berdasarkan gaya kognitif.

ANALISIS KEMAMPUAN LITERASI SPASIAL SISWA PADA MATERI TRANSFORMASI GEOMETRI
type: item
description: Abstract This study aims to determine the overall level of students' spatial literacy skills and analyse and describe each spatial literacy indicator on geometry transformation material. The type of research used is a quantitative approach with descriptive methods. This study used a sample of 100 students of class XII MIPA. The instrument used consists of a written test in the form of descriptive questions totalling 9 questions to measure students' spatial literacy skills. The research results obtained show that: 1) students' spatial literacy skills are classified in the medium category, but the average score is still far below the KKM score. 2) Judging from the visualisation aspect, the average acquisition of this indicator is better than the other indicators, namely 49.33, where some students have been able to sketch spatial objects through visual images based on contextual problems appropriately and completely. 3) Judging from the reasoning aspect with an average of 26.83, most students still do not understand the concept of geometric transformation well, so they cannot relate concepts and relationships of spatial objects and use both in calculations. 4) Judging from the communication aspect with an average of 30.92, there are still many students who are unable to express their ideas related to the relationship of spatial objects correctly. It can be concluded that the spatial literacy skills possessed by students are not yet qualified.
