This study explores and investigates the process of students’ mathematical thinking literacy in solving mathematical problems. This qualitative descriptive research used a test sheet consisting of one item adapted from the PISA mathematical problem model and interview guidelines, as the instrument. One male and two female participants were selected based on problem-solving characteristics. After that, task-based interviews were carried out to investigate the process of students’ mathematical thinking literacy. Data analysis was initiated by reviewing, reducing, and concluding all collected data to describe students’ mathematical thinking literacy in solving mathematical problems. The findings suggest that mathematical thinking literacy is initiated by understanding the problem (understanding), presenting the problem in a simpler form (specializing) to represent ideas, and creating patterns or relationships (generalizing). Based on the relationship between the problem, the subject predicts a solution (conjecturing) or determines the solution to the problem, re-checks (justifying) the problem-solving process to find a logical final result, and communicates the reasons (convincing) to convince the truth of the results obtained. The results of this study help teachers understand the process of students’ mathematical thinking literacy in solving mathematical problems so that it can be used to determine the appropriate strategy in the learning process to improve students' mathematical problem-solving abilities

One of mathematic topic that often considered difficult is linear equation. This research aims to develop “Matcha-Act” website as learning media for linear equation that is both valid and practical for mathematic learning. Adopting a Research and Development (R&D) framework, the study employed ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The subjects of this research were 8th grade junior high school students. The data gathered via media validation instruments and response questionnaires. The result indicated that the “Matcha-Act” website were valid and achieving a score of 3.2 or 80%. Furthermore, practicality test yielded a score of 3.1 or 77.5%. It means that “Matcha-Act” website-media were practical to use. The advantages of “Matcha-Act” website media include its accessibility and convenience, an engaging and interactive interface, and its ability to assist students in discovering concepts independently under teacher guidance. Consequently, the Matcha-Act” website is verified as a valid and practical learning media, making it suitable for mathematics learning, particularly on the topic of linear equations.

This research aims to develop a mathematical assessment instrument equivalent to the Academic Ability Test (TKA) for junior high school students who have good measurement quality. This research uses a Research and Development (R&D) approach by adapting the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. The instrument developed consists of three question items that are arranged based on the TKA preparation grid with emphasis on mathematical reasoning skills, problem solving, and critical thinking. The research subjects consisted of expert validators including experts in mathematics and educational evaluation experts, as well as 80 junior high school students as respondents to the instrument trial. The data collection technique is carried out through expert validation sheets and tests of student work. Data analysis was carried out descriptively to assess the feasibility of the instrument's contents, while empirical validity was analyzed using corrected item-total correlation and reliability was analyzed using Cronbach's Alpha coefficient with the help of IBM SPSS Statistics software. The results showed that all question items had a corrected item-total correlation value that was greater than the r-value of the table (0.220) so that it was declared valid. In addition, the results of the reliability test showed a Cronbach's Alpha value of 0.953 which was in the very high category. These findings show that the assessment instruments developed have a very good level of validity and reliability so that they are suitable for use as an alternative assessment to measure the academic ability of junior high school students that are in line with TKA standards.

Abstract: The purpose of this qualitative research is describing open-ended problem solving assessments for measuring the profile of student’s mathematical creative thinking, and describing student’s mathematical gender-based creative thinking profile. The assessments forms were open-ended problem solving sheet and interview guide. The research subjects were 3 female and 3 male sixth graders at one of elementary school in Malang, whose mathematical creative thinking capability regarded as high, fair, low level for each gender group. The students whose mathematical creative thinking high have all the three aspects of creative thinking: fluency, flexibility, and originality aspects of creativity. The students who have fair level of mathematical creative thinking fulfill only two aspects that are fluency and flexibility aspects. The students whose mathematical creative thinking low have only fluency aspect. Female students solve mathematical problems more fluently than boys. The male student who has high level of mathematical creative thinking has visual spatial ability better than the same level female student. Also the high mathematical profeciency female student has better mathematical reasoning ability than the male student of the same level.

This mixed-methods systematic review sought to assess how effective Augmented Reality (AR) is in improving spatial skills, aimed to evaluate the effectiveness of Augmented Reality (AR) in enhancing spatial skills and geometric understanding among primary school students, and to identify key factors for successful AR implementation in mathematics education. A comprehensive search of the Scopus database up to 21 March 2025 yielded 817 records, of which 26 peer-reviewed articles met the inclusion criteria following PRISMA guidelines. Quantitative data from experimental and quasi-experimental studies were synthesised using meta-analytic methods, while qualitative findings were coded and thematically analysed. The results indicate that AR interventions produced moderate to very large positive effects on spatial visualisation, mental rotation, and spatial reasoning, with an average effect size of 0.65 SD in geometry test scores compared to traditional methods. AR's interactive and visual affordances enabled students to manipulate and explore geometric concepts concretely, resulting in deeper conceptual understanding and increased engagement. Qualitative synthesis further revealed that successful AR integration is supported by structured teacher training, curriculum alignment, accessible technology, and collaborative classroom environments. However, limited infrastructure, teacher preparedness, and curriculum integration remain significant barriers. These findings suggest that AR can substantially improve primary education's spatial and geometric learning outcomes when implemented with appropriate pedagogical and institutional support. Future studies should prioritise longitudinal research, comparative evaluations, and the creation of policies to sustain and scale AR's benefits in diverse educational contexts.
