In studying geometry, it is common for students to make various errors when working on word problems. Although some students understand the example problems, they may be confused and make errors when presented with different questions. This study employed a qualitative descriptive approach to examine the types and causes of errors made by Grade 8 students from a junior high school in Pronojiwo, Indonesia. The study involved 40 students, with six students selected for interviews. Data were collected using descriptions and interviews. The research employed three procedural stages: preparation, implementation, and data analysis. Data analysis involved data reduction, data encoding, and conclusions. The analysis revealed that 23.3% of students made conceptual errors, 27% made procedural errors, and 44.5% made technical errors. The factors contributing to these errors included students' lack of focus on reading the questions, limited understanding of the material, haste in completing the questions, insufficient knowledge of the problems in the questions, and carelessness in checking their answers.

Understanding of students' mathematical concepts plays a very important role as a factor to support learning activities. In studying a concept students must understand previous mathematical material as a prerequisite material. Students' conceptual understanding of a material can be influenced by several factors, one of them is the cognitive style factor that has different for each student. Different cognitive styles can be seen from the field independent and field dependent cognitive styles. The importance of understanding students' mathematical concepts of a material that is influenced by students' cognitive styles, it is necessary to analyze students' understanding of mathematical concepts. This qualitative research aims to determine students' conceptual understanding of the prerequisite material and its relationship with students' cognitive styles, and the ways students use in solving existing problems. The results in this study showed there was a significant relationship between the cognitive style of each student and the understanding of mathematical concepts towards the prerequisite material. This is because the field independent cognitive style has a good level of conceptual understanding while the field dependent cognitive style has a low level of conceptual understanding, because they have different levels of conceptual understanding so each student has their own way to solve existing problems.

Minimum Competency Assessment is a component of the assessment as an assessment policy established by the Indonesia government in independent learning to assess the success of formal education in schools. The junior high school of Muhammadiyah 8 Batu has implemented learning innovations. However, it still needs to be improved, especially in integrating the involvement of students in creative and critical thinking, communication, and collaboration, and refers to the Minimum Competency Assessment. This Lesson Study mentoring activity aims to improve the quality of learning mathematics by using a contextual approach oriented to Minimum Competency Assessment. This mentoring activity used workshop and simulation methods. Four mathematics teachers attended the workshop and simulation. The results showed that the Lesson Study team produced a Minimum Competency Assessment for six grade 7 groups oriented contextual learning design that integrated students’ involvement in creative and critical thinking, communication, and collaboration, which was realized through lesson design. Model teachers and observers were enthusiastic and carried out Minimum Competency assessment-oriented contextual learning activities through Lesson Study well. Students gave a positive response and were very active while participating in learning. The mentoring activities of Minimum Competency Assessment-oriented contextual learning can be said to be effective. The learning designs prepared by the teacher can be implemented in other classes with relatively the same student characteristics.

This study investigates the mathematical representation processes of junior high school students in Indonesia when solving higher-order thinking Skills (HOTS) problems, using machine learning-based analysis Given the increasing volume of mathematics education research (PER) literature, traditional thematic analysis methods are inadequate for tracking developments and identifying future research directions. To address this, we applied the latent Dirichlet allocation (LDA) algorithm, a natural language processing (NLP) technique, to automate thematic analysis of Indonesian PER literature. Our sample comprised six junior high school students, categorized by mathematical ability into high (2 students), medium (2 students), and low (2 students). Data preprocessing included tokenization, stop-word removal, and stemming to prepare the text corpus for LDA modeling. HOTS problems, which require critical thinking and problem-solving skills, were used to assess students' abilities. The findings highlight three primary aspects of mathematical representation: visual, symbolic, and verbal. High-ability students demonstrated a propensity for using and transforming visual representations innovatively, while medium-ability students predominantly employed symbolic representations. In contrast, low-ability students exhibited limited or no changes in their representations. These results underscore the varying approaches to mathematical problem-solving based on ability levels. This study illustrates the effectiveness of NLP methods in thematic analysis, presenting an automated, comprehensive approach to understanding thematic developments in students' mathematical representation processes. By identifying research gaps and suggesting future research directions, our findings can inform scholars and educators aiming to enhance the quality of mathematics education. However, the small sample size limits the generalizability of the results, and future research with larger samples is recommended to validate and expand upon these findings.

Relational understanding constitutes students’ awareness of appropriate procedures to solve problems along with logical reasoning. Itis pivotal to help students solve problems in mathematics. It is necessary that the teaching of mathematics be directed to achieve relational understanding. Accordingly, students are capable of solving complicated problems in mathematics. This current research aims at analyzing and describing relational understanding and the patterns of answering questions of the fifth graders on integer operation. This study used a qualitative approach with a case study as the research design. Further, three students belonging to the fifth grade of Elementary School in Malang City, Indonesia, were set up as the research subjects. A test was administered to measure the subjects' relational understanding. All collected data were analyzed using an interactive technique. The result has indicated that the highly-proficient student was able to show excellent relational understanding. Besides, it was shown that the fairly-proficient student could show good relational understanding. The lowly-proficient student was shown to be able to achieve only half of the holistic criteria set for relational understanding. The patterns of answering the questions demonstrated by all students in all levels included jotting down the models, completing the models, and answering the questions. The highlyproficient student understood the information and wrote it down. Whilst the fairly-proficient student understood the information without translating it into the written form. At last, the lowly-proficient student did not pronounce any signals of understanding of the information.
