This study aims to describe the spatial ability of masculine male and feminine female students in solving geometric problems. The subjects of this study are one masculine male gender and one feminine female gender junior high school students who had the same mathematical ability. The subject selection was carried out using the Bem Sex Role Inventory instrument and Middle Semester Assessment scores, followed by conducting TPM (Problem Solving Test) and TPM-based interviews. The data collected from the TPM results and TPM-based interviews were then analyzed by applying the following steps: categorization, reduction, data presentation, interpretation, and conclusion. The results showed that subject-1 satisfied five indicators of spatial ability, namely spatial perception, visualization, spatial rotation, spatial relations, and spatial orientation so that it can be said to have high spatial abilities. On the other hand, subject-2 only meets three indicators of spatial ability, namely spatial rotation, spatial relation, and spatial orientation, so it can be said that female students have moderate spatial abilities. It is expected that the results of this study will be useful for future research and the mathematics learning process in schools

Contextual problems are non-routine problems that are related to real or daily life in the form of story questions, so that students are able to apply various contextual problems in learning mathematics. In solving contextual problems, it will be different from one student to another, this is because the creative thinking of each student is not the same. Creative thinking is the process of coming up with many ideas/possible answers of a problem, which has aspects of fluency, originality, and flexibility to generate the ideas. While the stages of creative thinking are: 1) synthesizing ideas, 2) building ideas, 3) planning ideas, and 4) implementing ideas. This research is a descriptive study with a qualitative approach that aims to describe the creative thinking of high school students in solving contextual problems in class X based on the level of creative thinking (creative and creative enough). The subjects in this study were 2 (two) students based on the level of creative thinking. Data collection was done in written form (Creative Thinking Test) and interview. Based on the results of research on creative thinking of high school students in solving contextual problems, information was obtained that: a) students with a creative level of thinking (creative) carry out steps in determining concepts, ideas sourced from everyday experience, generating different ideas from each problem with various patterns, determine and develop strategies to implement ideas based on the information received, but there are a few obstacles in implementing the final problem, but already have a strong concept, even though it is not shown how big the prize is through the stages of synthesizing ideas, building ideas, planning ideas, and implement ideas. b) students with a level of creative thinking (sufficient) carry out steps to recall arithmetic sequence formulas, based on the information obtained in the problem, generate different ideas/patterns based on the knowledge received by students during learning, determine and organize the ideas used, but not thorough in answering the questions, but the ideas given are correct and appropriate and not answering the final problem through the stages of synthesizing ideas, building ideas, planning ideas, and implementing ideas. The implication of this research in mathematics education and learning is to find out the steps for students' creative thinking, knowledge and strategies in solving contextual problems

The use of textbooks in the learning process tends to make learning less motivating for students. This is because textbooks primarily focus on delivering content without considering students' motivation and engagement. In addition, the integration of technology in schools remains relatively low. Therefore, an interactive e-module based on the ethnomathematics of Batik Anjuk Ladang and supported by GeoGebra was developed. The e-module serves as an alternative learning resource that promotes interactive learning. The integration of Batik Anjuk Ladang’s ethnomathematics provides contextual content to help enhance students’ self-learning motivation, while GeoGebra is used to offer visualization and increase the interactivity of the e module. This e-module was developed using the Plomp development model, which consists of three phases: preliminary research, development or prototyping, and assessment. The e-module focuses on Grade IX junior high school geometry transformation material and was developed using Flip PDF Professional and GeoGebra. The module was tested at SMP Negeri 2 Nganjuk with a group of Grade IX students. The quality of the developed e-module was evaluated based on validity, practicality, and effectiveness criteria. The study produced a detailed description of the e-module development process. The average material validity score was 86.31%, categorized as very valid— especially in terms of user-friendliness. The media validity score was 86.08%, also very valid with the same dominant criterion. The practicality score reached 85.09%, classified as very practical, with multimedia clarity as the most prominent aspect. The effectiveness of the e-module was demonstrated by an average N-gain score of 0.701, indicating a high category. Therefore, the developed e-module meets the criteria of being valid, practical, and effective for facilitating independent learning in geometry transformation.

Learning outcomes in mathematics, particularly in probability, are often uneven due to student’s diverse initial abilities and the limited application of differentiated instruction in a classrooms. This study was conducted to address this issue by implementing the Teaching at the Right Level (TaRL) approach, which focuses on tailoring instruction to students’ actual learning levels rather than their grade level. The purpose of this research is to examine how the TaRL approach can improve students’ learning outcomes in the topic of probability. A descriptive quantitative method was employed, involving 29 students in the experimental class and 30 in the control class. Data were collected through classroom observations of student and teacher activities, student response questionnaires, and cognitive assessments via pretests and posttests. The data analysis included N-Gain calculation, Shapiro-Wilk normality test, paired t-test or Wilcoxon test, and independent t-test or Mann-Whitney test. The results showed that TaRL encouraged active student participation according to their level: high-ability students worked more independently, medium-ability students required occasional guidance, and low-ability students engaged more actively in discussions with consistent support. Teachers successfully applied differentiated instruction based on TaRL principles throughout the discovery learning phases, ensuring structured and adaptive teaching practices. Student responses were highly positive, with many expressing greater enjoyment, engagement, and clarity during learning. A significant difference in learning outcomes was found between the experimental and control groups, indicating that the TaRL approach effectively enhances student achievement by aligning instruction with individual learning needs and promoting active participation in the learning process.

Mathematics is one of the sciences that emerged from culture, so mathematics and culture cannot be separated. Ethnomathematics is a field that combines mathematical concepts with the cultural aspects of society. Therefore, this study aims to describe the results of an exploration of Sidoarjo cultural ethnomathematics activities at Pura Jala Siddhi Amerta, focusing on six basic mathematical activities within the culture. This study employs a qualitative approach, utilizing an ethnographic method. The data obtained were collected through interviews and observations conducted by researchers with one of the administrators of Pura Jala Siddhi Amerta, using research instruments in the form of interview guidelines, observation sheets, and field notes. Then, the data will be analyzed using data analysis techniques of data reduction, data presentation, and conclusion drawing. The results showed that the form of ethnomathematics in Pura Jala Siddhi Amerta is related to the concept of number, geometric transformation, quadrilateral pyramid, and measurement. Therefore, it is hoped that teachers can use Pura Jala Siddhi Amerta as a bridge to teach math concepts, enabling students to understand the material more easily.
