Abstract

This study aims to develop a Nearpod-based mathematics learning media that is valid, practical, and effective in increasing the interest and learning outcomes of Grade X students at MA NU Lekok. The development model used is the ADDIE model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The instruments used in the research include expert validation sheets, practicality questionnaires, learning interest questionnaires, and pretest and posttest questions. The validation results from subject-matter and media experts indicated that the media falls into the "very valid" category. A limited-scale practicality test obtained a score of 90%, showing that the media is highly practical for classroom use. The effectiveness of the media was demonstrated by improved student learning outcomes, as evidenced by pretest and posttest scores, and by increased interest in learning, as measured through questionnaires. The t-test results showed a significant difference between the pretest and posttest scores. Therefore, the Nearpod-based learning media is effective in improving students’ interest and learning outcomes.

Abstract

Algebraic thinking ability and self-efficacy are essential components in mathematics learning; however, many students still experience difficulties in both cognitive and affective aspects. Therefore, an instructional approach that integrates these two domains is needed. This study aims to examine the effectiveness of a hybrid Problem-Based Learning (PBL) model combined with an Individual Group Learning (IGL) strategy in improving students' algebraic thinking ability and self-efficacy. This study employed a quantitative approach using a one-group pretest–posttest design. The participants were 15 tenth-grade students of SMA Syarif Hidayatullah Grati in the 2024/2025 academic year. Data were collected through algebraic thinking tests and self-efficacy questionnaires and analyzed using paired-sample t-tests, N-Gain, and effect size (Cohen's d). The results showed a significant improvement in both variables (p < 0.001). The mean score of algebraic thinking increased from 65.40 to 86.10, with an N-Gain of 0.59 (moderate category) and a large effect size (d = 1.20). Similarly, students’ self-efficacy improved from 66.80 to 86.53, with an N-Gain of 0.60 (moderate) and a large effect size (d = 1.25). The greatest improvement in algebraic thinking was observed in modeling and solving contextual problems, indicating PBL's effectiveness in promoting higher-order thinking. These findings indicate that the PBL-IGL hybrid approach is effective in enhancing both cognitive and affective learning outcomes. The novelty of this study lies in integrating individual and collaborative learning within a problem-based framework, while simultaneously focusing on algebraic thinking and self-efficacy. This study contributes to mathematics education by providing empirical evidence that a balanced instructional design can improve students' understanding and confidence in learning mathematics.

Abstract

This study aims to describe the algebraic thinking abilities of seventh-grade junior high school students on the algebraic operations material in terms of field-independent (FI) and field-dependent (FD) cognitive styles. This study uses a descriptive qualitative approach with two subjects, namely FI1 (field-independent) and FD1 (field-dependent), selected based on the results of the GEFT test and teacher recommendations. Data were obtained through written tests and interviews and analysed using six indicators of algebraic thinking ability: generalisation and abstraction, analytical and dynamic thinking, modelling, and organisation. The results of the study show that subject FI1 met all indicators well. FI1 could identify important information from the questions, construct mathematical equations accurately, and solve problems using relevant elimination and substitution strategies. He was also able to independently evaluate the results and construct answers in a coherent, logical manner. Meanwhile, subject FD1 showed more limited achievement. FD1 was quite capable of generalizing and abstracting, but there were still errors in copying information. In terms of analytical and dynamic thinking, as well as modelling, FD1 did not demonstrate adequate procedural understanding or verify answers. Nevertheless, FD1 still attempted to organize information and final results in a structured manner

Abstract

This study explores geometric concepts embedded in the ornaments of Tegowangi Temple through an ethnomathematical perspective. Previous studies on temple-based ethnomathematics have primarily focused on general geometric forms, with limited attention to specific concepts and their pedagogical relevance, particularly in the context of Tegowangi Temple. Addressing this gap, this research aims to identify and analyse the concepts of reflection, similarity, and circles within the temple’s ornamental structures. A qualitative exploratory design with an ethnographic approach was employed. Data were collected through observation, interviews, and documentation, and analysed using domain and taxonomic analysis to interpret mathematical representations within cultural artefacts. The findings reveal that reflection is evident in the symmetrical structure of corner kala ornaments, in the similarity of the yoni's proportional dimensions, and in circular concepts in the decorative patterns of the Perwara Temple. These concepts were derived through systematic visual and structural analysis of ornament forms. Conceptually, the study contributes to a deeper understanding of geometry in cultural contexts, while pedagogically, it provides contextual learning resources for junior high school mathematics

Abstract

This study aims to describe students’ mathematical literacy processes when solving PISA problems in the Space and Shape content domain, based on the three PISA literacy processes: Formulating, Employing, and Interpreting. This research uses a descriptive qualitative approach with three ninth-grade students as subjects, selected through purposive sampling: S1 (moderate ability), S2 (low ability), and S3 (high ability). Data were collected through a mathematical literacy test consisting of three PISA Space and Shape problems (Problem 1, Problem 2, and Problem 3) and semi-structured interviews. Data analysis was conducted through data reduction, coding based on literacy process indicators, data display, and conclusion. The results show that S1, in Problem 1, was able to fulfil all mathematical literacy processes (Formulating, Employing, and Interpreting). S2, in Problem 2, was only partially able to achieve the Formulating stage and experienced difficulties with the Employing and Interpreting stages. Meanwhile, S3, in Problem 3, also only partially achieved the Formulating stage and failed to achieve the Employing and Interpreting stages due to an inaccurate mathematical model and inappropriate procedures. These findings indicate that the level of mathematical literacy achievement is not always aligned with students’ ability categories but is influenced by the characteristics of the problem and the accuracy of mathematical modelling. Therefore, learning should emphasise modelling activities, meaningful application of procedures, and interpretation of results in real-world contexts.

Abstract

While classical methods and hisab methods based on spherical trigonometry and vector algebra are commonly used, this article introduces a more elegant, purely geometric alternative using Clifford Algebra (within the framework of Geometric Algebra). This method uses unit vectors in three-dimensional space to represent the positions of the observer and the Kaaba, then projects these vectors onto the local horizontal plane using geometric operations such as the dot product and the outer product. The results of the Qibla direction calculations for five major cities in Indonesia—Jakarta, Surabaya, Medan, Bandung, and Makassar—when compared with the spherical trigonometry and vector algebra methods, show high consistency, with a maximum difference of less than 0°. Further validation using data from the Qibla Locator also confirms the method's accuracy. Clifford Algebra has proven to be an accurate, intuitive, and computationally efficient approach, with great potential for applications in digital navigation systems, augmented reality, and science education. Thus, this method offers a powerful modern alternative for determining the direction of the Qibla through hisab
