This study explores how the traditional game Dakon supports students’ computational thinking in understanding number patterns. Computational thinking ability in this study includes four main indicators: decomposition, pattern recognition, abstraction, and algorithm. This study employed a case study design and a qualitative methodology and involved six students in grade VIII of junior high school who were purposively selected based on their level of mathematical ability. Data collection was conducted through observation of Dakon playing activities, number pattern-based written tests, semi-structured interviews as well as records. Data analysis was carried out, with triangulation of data from various sources to increase validity. The findings highlight strengths in decomposition and pattern recognition, while indicating the need for scaffolding in abstraction and algorithmic strategies. This finding confirms that the Dakon game not only strengthens mathematical understanding through a local cultural context, but is also able to build a deep and meaningful foundation of computational thinking. This research recommends the integration of traditional games as part of contextualized and fun math learning strategies to support acquiring skills for the twenty-first century.

Learning exponent concepts remains challenging for middle school students, particularly in developing problem-solving skills. This study aimed to examine the effectiveness of the MathShark game-based application integrated with a STEM approach compared to conventional mathematics instruction. A quasi-experimental design with a pretest–posttest control group was employed. The participants consisted of two groups of middle school students: an experimental group using the MathShark application and a control group receiving traditional instruction. Data were collected through problem-solving tests and analyzed using the Mann–Whitney U test and the Wilcoxon Signed-Rank test. The results indicated a significant improvement in students’ problem-solving skills in the experimental group compared to the control group (p < 0.05). These findings suggest that integrating game-based applications within a STEM framework has a positive effect on students’ understanding of exponent concepts and their problem-solving abilities.

This study aims to develop three types of assessments in mathematics learning for the Three Variable Linear Equation System material: initial, formative, and summative assessments. These three assessments are designed for use on a digital platform to enhance the efficiency of implementation and student involvement in the learning process. The study uses a Research and Development ( R&D ) approach with the ADDIE model consisting of five stages: analysis, design, development, implementation, and evaluation. The initial assessment in the form of a learning style questionnaire is distributed through Typeform to identify student learning characteristics. The formative assessment is designed in the form of an interactive quiz using the Nearpod application which includes multiple-choice questions. In the meantime, the summative evaluation is created as a context-based exam that gauges the knowledge, application, and reasoning dimensions. Four experts used Aiken's V test to validate the developed instrument, and Alpha Cronbach's reliability test was used to assess its dependability. With an Aiken's V > 0.80, the validation results demonstrate the instrument's high level of validity. The reliability test yields a moderately consistent Alpha Cronbach value of 0.45. The implementation's outcomes demonstrate that this technology-based evaluation can help identify student traits early on, offer feedback throughout the learning process, and measure learning success in a comprehensive way. Thus, creating this assessment could be a useful substitute for enhancing students' understanding of the Three Variable Linear Equation System.

Many junior high school students perceive mathematics as a difficult subject due to the use of instructional techniques that are less engaging and limited in context. As technology continues to develop, digital mediaincluding e-comicshave become innovative tools for enhancing students motivation and logicalmathematical reasoning. This quasi-experimental study involved 100 eighth-grade students from both an urban school in Surabaya, the capital city of East Java Province, and a rural school in JiwanMadiun, one of the districts in East Java, using a pretestposttest control group design, using a pretestposttest control group design. The experimental and control group from each location as the samples. A questionnaire to measure the students motivation and mathematics logical reasoning questions to assess logical-mathematical reasoning are the instrument. Statistical analysis included regression, Pearson correlation, and ANOVA test. The effect size (R = 0.466) demonstrated the strength of the model. The results revealed that e-comic-based learning significantly improved students motivation and logical- mathematical reasoning, with greater effects observed in urban schools. Furthermore, there was a moderately positive correlation between learning motivation and logical-mathematical reasoning abilities (r = 0.587). These findings suggest that integrating e-comics can effectively enhance learning outcomes while bridging urban-rural educational gaps

Mathematics is closely related to science because both require the ability to analyze, think logically, and systematically to understand. This study explores students' level of abstraction thinking in understanding the concept of exponent numbers and its implementation in science. This research uses a qualitative approach. The subjects in this study were students of the master's program in basic education. The data collection techniques used were tests and interviews. The results showed differences in identifying exponent numbers in low and high abstraction level students. Low abstraction level students perform problem-solving stages, such as identifying and writing down every information listed in the problem, using mathematical symbolization, performing number operations according to problem understanding, and checking again. Meanwhile, high abstraction level students performed problem-solving stages, such as identifying every piece of information in the problem without writing it on the worksheet, not writing the results of their understanding explicitly on the worksheet, not writing explicitly the model to be used, performing number operations without paying attention to the type of number because they already understood and they made a conclusion. Both level students applied the concept of exponent numbers in science for writing units and density.

Proportional reasoning is the foundation of mathematical abilities, including algebra, geometry, and statistics, and is influenced by students' mathematical dispositions. The transition from additive to multiplicative reasoning plays a crucial role in problem-solving. This study explores junior high school students' strategies in understanding geometric similarity through a qualitative case study involving three students in Surabaya selected through purposive sampling based on high, medium, and low mathematical dispositions This study uses a qualitative approach with a case study method. The subjects of the study consisted of three eighth-grade students purposively selected to represent high, medium, and low mathematical disposition, allowing an in-depth examination of how different dispositions influence proportional reasoning. The instruments used were similarity problem worksheets and semi-structured interview guidelines. Data were collected through student answers and interviews, then analysed through data reduction, data presentation, and drawing conclusions. The results showed differences in proportional reasoning strategies according to mathematical disposition: S1 at level 3 (Formal Reasoning), S2 at level 2 (Quantitative Reasoning), and S3 at level 0 (Non-Proportional Reasoning). Proportional reasoning develops when quantity coordination and multiplicative strategies are used in an integrated manner, in line with each student's mathematical disposition. Student with high disposition consistently use ratio-based multiplicative strategies, student with medium disposition use multiplicative strategies, while student with low disposition tend to use additive rules or random approaches. These findings are exploratory and can serve as a basis for studying misconceptions and developing proportional learning.

At this time, a lot of news about unemployment of higher education graduates became a special concern for the campus as the organizer. The solutions adopted include entrepreneurship education programs for students and graduates. But often entrepreneurship education programs that are carried out are not continuous and sporadic in order to obtain less optimal results. The entrepreneurship development program aims to provide entrepreneurship guidance for students and alumni of Universitas Islam Darul Ulum by prioritizing the concept of sustainable training and coaching and adjusting tenant issues. This program uses a three-phase of Participatory Action Learning System (PALS) approach, namely awareness, entrepreneurship capacity building, and institutionalization. The results were obtained that this program provided improvements in tenant management, produced science and technology-based products and formed cooperation with related parties.

Scientific literacy is one of the important literacies that children need to have. However, there are many findings that show the low level of scientific literacy in Indonesian children. "Panggon Moco" is one of the reading park communities (TBM) which was formed due to the communityÃ¢â‚¬â„¢s concern for the success of the literacy program. Until now, the literacy developed by this community is still limited to reading literacy. Therefore, it is necessary to develop other literacy such as scientific literacy. To answer this challenge, it is necessary to carry out a scientific literacy activities for children in the Panggon Moco community. A learning approach that has been proven to improve scientific literacy in children is STEAM (science, technology, engineering, art, and mathematics). The method of implementing this program includes several activities, namely (1) discussion and equalization of perceptions; (2) making Fun STEAM Lab books; (3) the STEAM experiment; and (4) STEAM literacy assistance. This activity is carried out offline and online. The results obtained from this program are increasing children's understanding of STEAM and increasing students' interest and motivation in learning.

Mathematical literacy in socio-ecological contexts remains underexplored, particularly when examined in terms of cognitive style. This study aims to describe the mathematical literacy processes of reflective and impulsive junior high school students when solving Minimum Competency Assessment (MCA) tasks that involve socio-ecological issues. A qualitative descriptive design was employed, involving two high-mathematical-ability students selected purposively and classified as reflective and impulsive using the Matching Familiar Figures Test (MFFT). Data were collected through socio-ecological MCA tasks on school waste generation and semi-structured interviews. The data were analyzed using thematic coding based on the PISA mathematical literacy processes (formulate, apply, and interpret). The findings indicate that reflective students demonstrated more systematic verification and deeper contextual interpretation. In contrast, impulsive students applied strategies more rapidly but showed reduced monitoring accuracy, resulting in calculation errors despite appropriate procedural strategies. These findings underscore the importance of considering cognitive processing characteristics in developing socio-ecological MCA tasks and learning strategies to support higher-order mathematical literacy.

Objective: This article aims to examine the implications for student learning by investigating student errors through the lens of the pigeonhole principle and the Javanese calendar. Method: The study used a descriptive qualitative research method and included six high school students and vocational students. Data collection involved tests and interviews. The researchers focused on Ethnomathematics problems related to the Javanese calendar system. Result: The analysis of student responses revealed several types of errors based on Watson's criteria for error analysis in problem-solving. These errors included inappropriate data, inappropriate procedure, and undirected manipulation. Students struggled with understanding the given information, selecting appropriate procedures, and applying logical reasoning. Novelty: Interestingly, the researchers found that when the students were provided with guidance and assistance, they were able to grasp the concepts and successfully solve the problems. This suggests that the students had the potential to understand the material but lacked prior exposure to the concepts, particularly the pigeonhole principle.
