Abstract

This article discusses the development of a project-based blended learning (PjBBL) module using a cognitive conflict strategy on the topic of geometric transformations to enhance mathematical spatial literacy. The objectives of this study are (1) to produce a valid, practical design of a PjBBL module with a cognitive conflict strategy, and (2) to determine the improvement in the mathematical spatial literacy of eleventh-grade senior high school students after implementing the module. This research is a design research using the Plomp model. The initial stage of the Plomp model, namely the preliminary research stage, is to identify the problems and needs required in learning. The second stage is prototyping, namely, compiling a prototype after obtaining the results of the initial investigation, followed by formative evaluation; the third stage is assessment. The data collection techniques and instruments used were interviews, observations, and mathematical spatial literacy tests. The results of the module development were evaluated based on three aspects, namely validity, practicality, and effectiveness, involving students from SMAN 1 Cicalengka as the research subjects. The research data were analyzed descriptively. The results showed that the design of the project-based learning teaching module using the cognitive conflict strategy was in the very valid category, with an obtained score of 84. Valid based on material and media experts from the results of the feasibility of content, presentation, language, contextual, and graphics (module size, cover design, and module content design). For the practicality value, a result of 86.3, including the very practical category, was obtained based on the results of the practicality test of student responses to the criteria of presentation, language, content, and time. The effectiveness of the module is evidenced by an increase in students' mathematical spatial literacy, with high N-gain and a large effect size. Keywords: project-based learning, cognitive conflict strategy, mathematical spatial literacy.

Abstract

This study presents a bibliometric analysis of research on higher-order thinking skills (HOTS) in mathematics education. The objectives are to examine publication distribution and identify leading journals, authors, institutions, and countries. Data were retrieved from the Scopus database and analyzed using VOSviewer software. A total of 104 articles published between 2004 and 2022 were reviewed. Various visual representations, including graphs, tables, charts, and maps, were used to present the findings. The results show that HOTS research in mathematics education is closely associated with problem-solving, mathematics learning, and assessment. Eurasia Journal of Mathematics, Science, and Technology Education emerged as the most prominent journal, while Universiti Teknologi Malaysia was identified as the most influential institution, with Malaysia playing a significant role in this research domain. These findings provide a comprehensive overview of the research landscape and offer directions for future studies in mathematics education. Based on these results, suggestions for future research are proposed.

Abstract

Rendahnya kemampuan literasi matematis siswa masih menjadi tantangan dalam pembelajaran matematika. Salah satu upaya untuk mengatasinya adalah dengan menghadirkan asesmen yang tidak hanya mengukur kemampuan kognitif, tetapi juga relevan dengan konteks kehidupan siswa. Penelitian ini bertujuan untuk mengembangkan dan mengevaluasi instrumen tes berbasis literasi dengan konteks kearifan lokal Indramayu pada materi bilangan bulat. Penelitian menggunakan design research model Plomp yang meliputi tahap investigasi awal, pengembangan prototipe, dan evaluasi. Instrumen divalidasi oleh dua dosen pendidikan matematika dan dua guru matematika, serta diuji coba kepada 35 siswa SMP Negeri 1 Terisi. Hasil penelitian menunjukkan bahwa instrumen berada pada kategori sangat valid, memiliki reliabilitas yang cukup, tingkat kesukaran mudah, dan daya pembeda yang baik. Selain itu, hasil angket menunjukkan bahwa instrumen tergolong praktis digunakan dalam pembelajaran. Temuan ini menunjukkan bahwa integrasi konteks kearifan lokal dapat mendukung pengembangan asesmen literasi matematis yang lebih kontekstual dan bermakna.
