This study aims to explore students' algebraic thinking skills in solving Trends International Mathematics and Science Study (TIMSS) problems in terms of accommodator learning styles. The research design used is a case study with a qualitative analysis approach. The results showed that accommodating subjects were able to meet the indicators of algebraic thinking, namely generalization, abstraction, analytical thinking, dynamic thinking, and modeling. However, the lack of accuracy in performing calculation operations causes the answers obtained by the subject to be less precise on abstraction, analytical thinking, and dynamic thinking problems. The characteristics of subjects with accommodator learning styles who are more likely to use intuition in solving problems influence students' ability to solve problems related to algebraic thinking.

This study aims to investigate the algebraic thinking skills of fifth grade elementary school students in solving functional dimension problems. The type of research is descriptive qualitative. The subjects in this study were 131 grade 5 students from two private elementary schools in Surakarta, Central Java, Indonesia. The data collection instrument used was 5 questions on the dimension function algebraic thinking test adopted from Raslton which consisted of 2 numerical pattern questions and 3 picture pattern questions. Prior to use, the questions were first validated by three elementary school mathematics learning experts and tested on 10 students who were not included as research subjects. This research is limited to data analysis of 89 students who belong to the category of moderate algebraic thinking skills obtained from the test results. Data analysis was carried out by analyzing students' answer documents in solving algebraic thinking test questions. Document analysis is focused on solving steps and strategies used to solve problems. The results showed that students were more able to solve linear patterns than nonlinear patterns. Students are also more able to solve numerical patterns than picture patterns. In addition, the strategy used to solve numerical patterns is to determine multiples of numbers and identify the differences between terms in the pattern. Whereas in solving of picture patterns, the strategy used is to draw patterns and identify differences between terms in patterns. This study concluded that most of the subjects in the moderate category were able to demonstrate algebraic thinking skills in functional dimensions.

This study explores students’ instrumental understanding of spatial geometry problems, accounting for differences in initial mathematical ability. Many students tend to solve geometry problems procedurally without sufficient conceptual understanding, while research that examines explicitly instrumental understanding in spatial contexts remains limited. A qualitative case study design was employed involving 25 eighth-grade students from a public junior high school in Pagar Alam City, South Sumatra. Data were collected through written tests and in-depth interviews with six students representing high, medium, and low levels of mathematical ability. The analysis was guided by four indicators of instrumental understanding: recalling concepts, identifying concepts, selecting appropriate solution strategies, and representing concepts visually and in written form. The findings indicate apparent differences across ability levels. Students with high initial mathematical ability consistently fulfilled all four indicators across various spatial geometry problems. In contrast, students with medium and low ability demonstrated partial fulfilment of the indicators, particularly in topics such as cylinder volume and triangular prisms. These results suggest that students’ initial mathematical ability plays a crucial role in the development of instrumental understanding. Therefore, differentiated instructional strategies aligned with students' ability levels are recommended to support balanced procedural and conceptual learning in spatial geometry.

The students formation of mathematical concepts was still relatively weak. Data from the PISA showed that procedural skills still dominate students' conceptual understanding. The purpose of this study was to describe the students' concept formation in solving trigonometric problems. This study used a qualitative approach with a case study design. The subjects were three tenth-grade students from one of the high schools in the Boyolali district, Central Java. The instruments included trigonometric tests and in-depth interviews. Then the data was analyzed through reduction, presentation, and conclusion. The results showed that students with high trigonometric ability can fulfill all indicators of concept formation and connect trigonometric concepts with others. Furthermore, the student with medium trigonometric ability, although he can fulfill all the indicators of concept formation, has errors in the calculation process and unable to connect trigonometric concepts with other mathematical concepts. A student with low trigonometric ability is only able to perform simple solutions, and difficulties in connecting trigonometric concepts with others and explaining the steps of the solution. The implications of this study are the importance of pedagogical intervention in strengthening students' conceptual understanding and providing concrete experiences in trigonometry, especially for students with medium and low abilities.

Relational reasoning plays an important role in helping students to understand mathematical concepts. The student's ability to distinguish patterns or objects is one of the understandings of mathematical concept indicators. The anomaly dimension is part of the relational reasoning that students need to be able to determine a pattern or object in mathematics. This study aims to reveal the student's relational reasoning ability of anomaly dimension in solving number pattern problems in terms of gender differences. The subjects of this study are 52 grade-8 students in one of Muhammadiyah Junior High Schools in Kartasura. We used two similar problems on number patterns to disclose the student's ability to identify the pattern deviation in solving problems. The two selected students had relatively similar in their mathematical abilities. The finding showed that female subject met the three anomaly dimension indicators: identification, interpretation, and adaptation. Conversely, male student cannot fulfill the anomaly indicators. He cannot recognize pattern deviation in the formed mathematical model. He also failed to identify a pattern different from the two problems. Although the subjects interviewed were limited, the finding provided the insightful into the differences in anomaly reasoning abilities in male and female students
