The mission of positive psychology is to mitigate negative emotions while bolstering positive ones, thereby influencing student engagement in classroom learning activities, including mathematics. This study elucidates the Realistic Mathematics Education (RME) approach within the framework of Islamic teachings—specifically, inheritance law and charity—in the context of fractions and number operations. Its objective is to alleviate mathematics anxiety, a prevalent negative emotion, and enhance well-being during mathematical learning. Drawing upon flow theory from positive psychology, the research endeavors to optimize mathematical well-being by crafting appropriately challenging questions. Employing a descriptive qualitative methodology, the study focuses on an Indonesian mother and her ten-year-old son, residing in Uithoorn, Amsterdam, Netherlands, belonging to minority groups in ethnicity and identity, with religion being a significant aspect of their lives. Data collection involves observation, interviews, tests, and documentation, with analysis employing data reduction, presentation, triangulation, and verification techniques. The study utilizes socio-religious problems as a context, one of the characteristics of RME, such as inheritance division, to design mathematical challenges. The findings demonstrate a marked transition from math anxiety to math well-being, manifested through heightened enthusiasm and cheerfulness in learning mathematics, particularly by the mother. Noteworthy transformations include increased engagement, generous gestures towards the teacher, and frequent smiling, contrasting with previous instances of math anxiety during learning sessions. Furthermore, the results indicate that RME facilitates comprehension of mathematical concepts and fosters understanding of the intersection between mathematics and Islamic life among minority groups, as detailed in this article.

Recognising the pivotal role of effective teaching practices in enhancing student learning outcomes, the National Council of Teachers of Mathematics (NCTM) has outlined a comprehensive framework of key strategies. However, empirical research on these practices remains limited. Therefore, this study aimed to investigate the extent to which mathematics teachers apply NCTM-identified effective teaching practices and examine potential differences attributable to teachers' gender and teaching experience. Adopting a quantitative approach and employing a descriptive survey, the study systematically assessed eight designated practices using a validated observation checklist in the Jazan Education Administration, observing 38 mathematics teachers during routine classes. The results indicated a moderate level of implementation overall, with ten practices demonstrating high application. Statistical analyses found no significant differences in practice implementation based on gender or teaching experience at the .05 level. The limitations included the study's relatively small sample size, potentially limiting generalisability, and the observational nature of the checklist, which may not fully capture nuanced teaching dynamics. Future research could focus on developing training initiatives to enhance educators' application of NCTM-recommended practices and undertake qualitative inquiries to understand barriers to integration and teachers' attitudes towards these practices. Finally, this study contributes to the discourse on effective mathematics teaching by providing empirical insights into current practices and highlighting avenues for further investigation and professional development in educational settings.

Despite the growing interest in contextualizing mathematics education, research integrating Qur’an contexts into mathematics instruction remains limited. Prior studies have largely concentrated on conventional teaching methods, Qur’an-centered instruction, or Problem-based Learning (PBL) as independent approaches. This study addresses a critical gap by integrating Qur’an contexts into integer learning, supported by problem-based learning and facilitated through a technology-enhanced Electronic Student Worksheet (E-SW). The primary objective of this study is to design and assess the reliability and applicability of a Quran-based E-SW using the PBL framework for teaching integers to 7th-grade junior high school students. Employing a Research and Development (R&D) methodology with the ADDIE development model—comprising analysis, design, development, implementation, and evaluation phases—this research utilizes expert validation sheets and student practicality questionnaires as instruments. The study sample consists of 7th-grade students from SMP IT LHI Yogyakarta, with class 7B selected through purposive sampling. Validation results indicate that the E-SW meets established validity criteria, with scores from subject matter and media experts reaching 99 and 91, respectively, both classified as "Good." Practicality testing revealed positive student responses, yielding a practicality score of 61, categorized as "Practical." Furthermore, a paired sample t-test demonstrated a statistically significant improvement in student performance between pretest and posttest results, with a significance (2-tailed) value below 0.05 and an average N-Gain score of 0.4391, which is classified as moderate. These findings suggest that the Quran-based E-SW, structured around the PBL model, effectively enhances students' problem-solving abilities and is suitable for educational use.

Financial literacy is a knowledge and attitude about finance and is a 21st-century skill. As a knowledge, a cognitive factor of a person will impact their financial literacy skill. Through a bibliometric analysis study of 274 documents published from 1994 to 2022 in the Scopus database, we found that mathematics literacy is the cognitive factor of one's financial literacy skill. The OECD and several studies offer intertwined concepts, financial literacy and mathematics, to be presented in the mathematics curriculum in primary and secondary schools. After we got the bibliometric results, we surveyed several junior high schools in Yogyakarta to learn more about this issue. A total of 15 mathematics teachers participated in this survey, randomly chosen in junior high school. We got information stating that mathematics teachers used financial terms as a social arithmetic context, did not teach financial knowledge and attitudes, and never heard 13 from 17 financial terms in the survey. Furthermore, we present a framework for implementing financial literacy in mathematics through three dimensions, content, context, and process. The dimension content consists of mathematics' and financial content. On the other hand, the dimension context is related to education and work, home and family, and individual and societal. As a cognitive process, the dimensions of the process are based on Bloom's Cognitive stages. The potential for future research is developing learning activities and implementing them in the independent curriculum, which impacts schools' ability to use project-based learning, which is the most approach to implementing financial literacy in mathematics classes.

Equations are often used in mathematics and other subjects, which means that a media can teach students how to solve equations, particularly linear equations of two variables, or Sistem Persamaan Linear Dua Variabel (SPLDV) as it is called in Indonesian, is needed. However, most teachers are still focused on developing the learning process and teaching materials rather than developing an application technology-based learning media. As we know that technology-based learning is currently the focus of teaching and learning activities in the digital era, especially learning after the pandemic. This study aimed to develop an application that can be a reference for teaching media in learning activities to improve students’ mathematical understanding and ability. The developed application is named, Integrated and Convenient Android-based Simulation or Simulasi Android Terpadu dan Nyaman, abbreviated as SANTUY. This development study with Analysis, Design, Development, Implementation, and Evaluation (ADDIE) model, explained in detail in the paper, took seventy-five subjects consisting of six expert validators, nine users, and sixty students. The expert validators comprised three media experts and three material experts. The evaluation stage involved students from two groups, each consisting of thirty students. The results showed that the average percentage of the feasibility of the SANTUY SPLDV solution simulation-assisted application with differential learning nuance was 79.62%, which means the application is adequate. The level of usefulness of the SANTUY SPLDV solution simulation-assisted application with differential learning nuance was 86.11%, which is categorized as “excellent”. In addition, using the SANTUY SPLDV application had a direct positive influence on improving students’ mathematical understanding and ability.

Due to the poor instruction process during the Covid-19 Pandemic, especially in mathematics, students frequently need help with data literacy. To overcome these obstacles, they must improve their thinking skills. This study aims to enhance the quality of mathematics instruction, especially students' thinking skills, by implementing Lesson Study to develop sharing and jumping tasks. This qualitative descriptive research was conducted at one of the senior high schools and universities in Manokwari, West Papua, with their students as the research subject. The lesson study was implemented in two cycles through instruction at school and lectures at the university. The lesson study consists of three processes: plan, do, and see. The hypothetical learning trajectory was developed at the lesson design stage and then tested at the teaching-learning stage. The open class results were then analyzed during the reflection step to redesign the sharing and jumping tasks. The success of the research was determined through field notes taken from teachers and students. The frequency distribution table is used as the topic matter. The findings revealed that students' thinking skills developed, indicating they were more interested than in the previous teaching and learning process. The learning process was more exciting and enhanced conceptual comprehension. Because learning was communicable, students were more satisfied. They were more engaged and required further thought to comprehend the topic matter. Also, they produce a variety of responses, which is only feasible if they are capable of critical thought.

Nowadays, digital technologies are crucial in supporting students in geometry in secondary mathematics classrooms. However, in some cases, the role of visual function in technology was only utilized for seeing and conjecturing, not for experimenting, while to develop a relational understanding of geometry concepts, students should actively participate in the learning process. To address the issue, this study investigated how students learn geometry with digital technology assistance based on students' diversity in their mathematics abilities. A task with a dynamic geometry software called Techno-based Mathematical Tasks (TbMT) was designed to assist students in exploring geometrical activities and solving a problem through investigations on tessellation. This research employs educational design research and focuses on the preliminary design by conducting a pilot study on three students based on the diversity in their ability in mathematics classrooms, i.e., low, middle, and high. As part of data collection, we captured students' works to examine critical information in their responses based on their differences in abilities. We collected the data through online meetings and recorded the data. We analyzed students' work from the recording by capturing critical information. The results revealed that the TbMT might provide students with opportunities to learn by exploring tessellation activities that might contribute to students' understanding of geometry concepts. Due to the limited number of participants in this study, further research can be an opportunity to expand the number of participants to enhance the contribution to the literature with more comprehensive empirical evidence.

The study material on circle areas is contextually oriented and aids students in comprehending their surrounding environment. Higher-order thinking skills are imperative for the success of circular learning, as they help students grasp concepts holistically and solve concept problems. "What-if" questions can enhance students' higher-order thinking skills through problem-solving activities, fostering critical and creative thinking. However, applying "what-if" questions is limited to serving as problem-posing triggers, resulting in minimal variation in the material. Therefore, this study aims to design a learning trajectory for the area of circles based on "what-if" questions to enhance students' higher-order thinking skills. This research also addresses the gap by utilizing "what-if" questions to construct and evaluate circle area learning activities. We employed design research as the research method, conducted in three stages: preliminary design, experimental design, and retrospective analysis. The results demonstrated that the designed learning trajectory enhanced higher-order thinking skills in various aspects. Students exhibited critical thinking and profound analysis when working on worksheets and addressing the provided problems. Moreover, students showcased creative and divergent thinking abilities, enabling them to generate alternative problem solutions. Furthermore, optimizing technology usage and emphasizing reasoning in learning should be augmented to enhance student motivation and foster innovative learning.

Mathematical creative thinking skill often becomes the orientation of mathematics learning, aiming to enhance students’ creativity in mathematics. Recognizing that creativity encompasses the capacity for thinking creatively and creativity disposition is essential. Building on this conceptual foundation, the primary objective of this study is to develop a comprehensive model illustrating the relationship between students' aptitude for mathematical creative thinking and their creative disposition. The research methodology employed in this study aligned with the framework of cause-and-effect analysis. The study cohort consisted of 36 students, carefully selected by a cluster random sampling technique. The research instruments included a mathematical creative thinking ability assessment and a creative disposition scale. The data was analyzed using the Non-Recursive Structural Equation Modeling. The results showed the reciprocal cause-and-effect dynamic between mathematical creative thinking ability and creative disposition, exhibiting a mutually influential relationship with determination coefficients of 21.83% and 21.05%. This shows that mathematical creative thinking ability is better at explaining mathematical creative disposition than mathematical creative disposition explaining mathematical creative thinking ability, with a relatively small difference (0.78%). This study also concluded that an optimal approach to mathematics pedagogy entails a balanced and simultaneous focus on nurturing mathematical creative thinking ability and disposition.

Current research indicates the presence of highly skilled and motivated students with robust computational thinking backgrounds seeking opportunities to leverage their expertise in driving innovation and success in this era. These studies also reveal that students' computational thinking skills vary widely depending on educational resources, curriculum emphasis, and individual aptitude. Nonetheless, there is a growing recognition of the importance of fostering these skills, with efforts underway to integrate them more comprehensively into education systems worldwide, including in Indonesia and Japan, as representatives of developing and developed countries. Therefore, assessing the competency of computational thinking in these two countries would be intriguing. The descriptive qualitative research method was employed to delineate the computational thinking competencies of students in Indonesia and Japan. Student worksheets, specifically designed for this purpose, were utilized to gauge the development of these competencies during the learning process using the Scratch application. The results revealed that students employed various strategies in solving the given geometry problems. On the other hand, geometry is one of the mathematics topics that can identify students' computational thinking using this application. These findings were utilized to categorize students' computational thinking skills in the two countries and to identify potential obstacles students experienced in their efforts to enhance these skills. Nevertheless, these constraints offer significant insights into potential areas for future investigation and enhancement. Subsequent endeavors could prioritize conducting experiments by implementing specific learning approaches or methods that have demonstrated effectiveness in improving students' computational thinking skills. This study not only underscores the potential for expanding research on students' computational thinking skills but also provides an overview of the learning process, learning culture, and students' competence in solving geometry problems with tiered difficulty levels using their computational thinking skills.
