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 research was conducted to assess the quality of Scaffolding and visualization in the presentation of the Mathematics Module material for Grade X KD 3.2 regarding 3D vector material. The approach used in this research is a qualitative descriptive approach, which is carried out by analyzing the structure of the material, illustrations, example questions, and exercises provided in the module using content analysis techniques. The focus of the analysis conducted leads to several main aspects, including: (1) The sequence and form of Scaffolding presented as support in understanding the concept gradually, and (2) The effectiveness of visualization to help define and organize spatial vector data in space. This research resulted in a finding that the module has used Scaffolding with a tiered presentation of concepts, starting from the initial stage, namely the introduction of vector material in space to the stage of applying operations on vectors. However, on the other hand, it was also found that there are several stages of this Scaffolding that are not consistent, namely in the transition from examples to exercises which require a higher level of independence. Based on the visualization, the module utilizes spatial coordinate diagrams and vector arrow representations. However, some visuals lack detail in depicting orientation and depth in space, potentially leading to misconceptions among students. Overall, the module provides sufficient support for learning, but further strengthening of conceptual visualizations and more systematic Scaffolding is needed to optimally facilitate students' spatial thinking.
