Abstract

Generalization ability need to be encouraged in learning mathematics, students with generalization abilities can expand and transfer knowledge to practical knowledge. This research aims to develop learning material based on realistic mathematisc approach that oriented to generalization ability. The learning materials'developed is lesson plans and student worksheets. This is research and development with an ADDIE model. The instruments used in this study were the evaluation sheets, response questionnaire for teachers and students and tests of mathematical generalization ability.  The data analysis technique used was descriptive qualitative and quantitative. The design of the learning materials focuses on aspects of the mathematical generalization ability of high school students by presenting real problems. Student activities are designed to solve real issues related to pattern analysis, focus on student contributions to find conjectures, and design interactions so students can proceed to the abstraction stage using concept linkages. So students can make conclusions regarding the given concept in response to such issues. The results show that the validity qualifications of lesson plans and student worksheets are good and very good, the practical qulifications are very good. The learning materials comply with effective based on completeness tests of generalization ability of 82.26 with good qualifications

Abstract

The aims of this study is to analyze publications on early algebra in middle schools to contribute to the development of related literature. A total of 234 articles on early algebra published in various Scopus databases between 2013 and 2024 were retrieved and analyzed through a bibliometric analysis approach and 19 articles through a Comprehensive Meta Analysis (CMA). The results showed fluctuating trends in research related to early algebra in middle schools. The surge in publications using VOSviewer and RStudio from 2013 to 2024 did not align with a corresponding increase in average citations, contributing to a stagnation in the average citation per year. The noticeable upward trend in the volume of publications on early algebra since the beginning of 2013 indicates a dynamic and evolving research landscape in this field. This consistency suggests a widespread and sustained interest in early algebra research beyond the confines of a single country, further emphasizing its global relevance and significance. Integrating multimedia technology into early algebra instruction significantly enhances student learning outcomes. Moreover, access to technology and enhanced learning resources through technology integration can play a more crucial role in improving the effectiveness of early algebra learning in countries with lower income levels.

Abstract

This study investigated the multidimensional landscape of students' perceptions of mathematics learning using principal component analysis (PCA). Data were collected from 102 high school students (grades 9-12, mean age 16.2 years) in Indonesia. The survey, adapted from validated scales including the Fennema-Sherman Mathematics Attitudes Scales and the Attitudes Towards Mathematics Inventory, assessed various aspects of mathematics learning perceptions. Analysis revealed fifteen initial components that were subsequently consolidated into two major factors. The first factor encompassed variables related to external and environmental aspects: learning interest, parental support, motivation, difficulties, resources, school facilities, approaches, classrooms, materials, and methods. The second factor comprised internal and cognitive elements: conceptual understanding, self-confidence, learning models, anxiety, and techniques. The PCA results highlight the complex interplay between cognitive, affective, and contextual factors in mathematics learning. The findings suggest that interventions should adopt a holistic approach, addressing both environmental and cognitive dimensions. This research contributes to educational practice by identifying key areas for targeted intervention while demonstrating the effectiveness of PCA in understanding complex educational phenomena. Future studies could explore these factors' generalizability across different educational contexts and their longitudinal evolution.

Abstract

This study examines the relationship between the knowledge prescribed in the school curriculum, the knowledge enacted by mathematics teachers, and the knowledge constructed by students in learning trigonometric ratios through the perspective of Didactic Transposition Theory. A qualitative intrinsic case study was conducted with one mathematics teacher and 22 tenth-grade students in an Indonesian senior high school. Data were collected from curriculum documents, teaching notes, classroom observations, interviews, and two tests designed to capture students’ conceptual understanding. The data were analyzed using document analysis, content analysis, and descriptive analysis. The findings show that although students’ understanding of trigonometric ratios improved during instruction, the enacted classroom practices mainly emphasized trigonometric ratios as fixed relationships among the sides of right triangles. Consequently, students tended to interpret sine, cosine, and tangent primarily as geometric ratios rather than as functions of angles. This emphasis limited students’ ability to connect geometric reasoning with functional interpretations of trigonometric relationships. These results highlight the importance of strengthening instructional coherence in curriculum implementation so that classroom teaching better supports the development of both geometric and functional understanding of trigonometry.

Abstract

Creative thinking is widely recognized as a core component of higher-order thinking in mathematics education; however, its development among Indonesian students remains a persistent challenge, as reflected in large-scale international assessments such as PISA 2018. Differences in students’ cognitive styles particularly reflective, impulsive, and slow-inaccurate styles are assumed to shape cognitive processing and mathematical problem-solving performance, yet empirical evidence remains limited. This study aims to examine students’ creative thinking ability in mathematical problem solving from the perspective of these cognitive styles. Employing a qualitative descriptive approach, the participants were eighth-grade students from SMP Negeri 2 Sumbergempol Tulungagung, classified using the Matching Familiar Figure Test (MFFT). Data were obtained through problem-solving tests and semi-structured interviews and analyzed through methodological triangulation. The findings indicate that students with reflective cognitive styles exhibit a high level of creative thinking, characterized by fluency, flexibility, and originality. In contrast, students with impulsive and slow-inaccurate cognitive styles demonstrate moderate creative performance, predominantly reflected in elaborative responses. These results highlight the need for differentiated instructional strategies that align with students’ cognitive characteristics. The study contributes to the growing body of literature on cognitive style-based instruction and offers pedagogical insights for fostering creative thinking in mathematics classrooms.
