Abstract

junior high school level. However, in practice, it often leads to misconceptions among students. One of the main contributing factors is the way the material is presented in textbooks, which serve as the primary reference for both teachers and students. This study aims to analyze the potential misconceptions found in two mathematics textbooks, namely Matematika SMP/MTs Kelas VII Semester 1 published by BS Press (2017) and Persamaan dan Pertidaksamaan Linear Satu Variabel written by Winie Ananda (2022). This research employed a descriptive qualitative approach using content analysis. The instrument focused on three aspects: (1) the rule of reversing inequality signs when multiplying or dividing by negative numbers, (2) the conceptual differences between linear equations in one variable (PLSV) and linear inequalities in one variable (PtLSV), and (3) the representation of solution sets on the number line. Thefindings indicate that both textbooks still contain potential sources of misconceptions. The use of the term “root of PtLSV” is conceptually inaccurate, the rule of sign reversal is presented only procedurally, the distinction between PLSV and PtLSV is insufficiently emphasized, and the graphical representation on the number line is not adequately explained. These results highlight the need to improve the presentation of PtLSV materials in textbooks and encourage teachers to provide stronger conceptual explanations to foster meaningful learning.

Abstract

This study aims to analyze students' geometric reasoning in solving triangle problems in Euclid Geometry through the representation of Ulos Batak motifs and identify the types of errors that occur. This study uses a descriptive qualitative approach with the subjects of 15 students in the fourth semester of Mathematics Education. The instrument was in the form of 5 HOTS-based description questions, and the data were analyzed using the Miles and Huberman model and Newman Error Analysis (NEA). The results showed that students' geometric reasoning skills were in the high category, with 80% in the high category and 20% in the medium category, and an average score of 87.4%. The aspects of understanding and transformation are relatively good, while reasoning and connection are still low. The dominant error is interpretation error. Thus, the use of Ulos Batak motifs supports geometry learning, but it needs to be strengthened in the aspects of interpretation and concept connection.
