Abstract

This study aims to analyze students’ difficulties in solving PISA Level 4 equivalent mathematical literacy tasks based on the Formulate, Employ, and Interpret (FEI) processes and to identify scaffolding implications at each stage. A descriptive design with quantitative and qualitative approaches was employed involving 28 ninth-grade junior high school students who worked on four PISA Level 4 equivalent tasks. Quantitative analysis was used to map students’ achievement profiles across the FEI processes, while qualitative analysis examined selected students’ written solution traces. The results indicate that students’ difficulties were most prominent at the formulate stage, as reflected in incomplete mathematical representations, although some students were able to carry out procedures (employ) and obtain correct final answers. Procedural errors and conceptual misconceptions persisted at the employ stage, whereas at the interpret stage students tended to stop at numerical results without adequately relating them to the problem context. These findings suggest that the FEI processes are interconnected and conceptually hierarchical, although they are not always explicitly articulated in students’ written responses, and provide a basis for future action-oriented research aimed at improving instruction and students’ performance in PISA assessments.

Abstract

This descriptive qualitative study maps the locations and etiological factors of mathematical errors among eighth-grade students in solving Linear Equations in Two Variables (LETV), analyzed through cognitive style typologies. Using purposive sampling, five representative subjects two Field Independent (FI) and three Field Dependent (FD) students—were selected. Data triangulation involved the Group Embedded Figures Test (GEFT), a problem-solving test, and clinical interviews, analyzed through an interactive model of reduction, display, and verification. Results indicate that FI students commit conceptual errors due to lack of thoroughness, principle errors from personalized methods, and procedural errors from unsystematic approaches. Conversely, FD students exhibit conceptual errors from misunderstanding prerequisites, principle errors in mathematical modeling, and procedural errors due to inappropriate methods and low arithmetic accuracy. The study emphasizes the necessity of instructional differentiation: teachers should provide systematization exercises for FI students to minimize carelessness and intensive scaffolding for FD students to improve their transformation of word problems into formal models. This approach aims to reduce cognitive barriers by addressing specific learning characteristics.

Abstract

This study aims to analyze the disparity in geometry thinking levels of junior high school students on circle material based on Van Hiele’s theory. This research employed a descriptive qualitative approach involving 42 ninth-grade students of SMP Negeri 11 Lubuklinggau selected through random sampling. Data were collected through tests and informal interviews and analyzed using the interactive model of Miles and Huberman. The results indicate a marked disparity in students’ geometry thinking levels. Most students have not achieved mastery at Level 0 (Visualization) with 88.1% and Level 1 (Analysis) with 81.0%, as shown by their inability to identify elements of a circle visually. At Level 2 (Informal Deduction), 45.2% of students have not reached mastery, although some were able to apply concepts correctly. These findings suggest that students’ abilities are still dominated by instrumental understanding without adequate relational understanding. Furthermore, this study reveals the presence of epistemological learning obstacles, characterized by a leap in thinking without strong mastery of fundamental concepts.

Abstract

This research is driven by the importance of computational thinking as a crucial foundation for students to face 21st-century challenges. Computational thinking is a logical and systematic problem-solving process that includes the ability to recognize patterns, perform decomposition, and design algorithms. In mathematics education, this ability is categorized as Higher Order Thinking Skills, which functions to simplify complex problems, specifically in the topic of Systems of Linear Equations in Two Variables. However, in reality, the computational thinking skills of students in Indonesia are still low or below the minimum mastery criteria. Therefore, this study aims to analyze the obstacles to students' computational thinking skills in solving the problems using the Systematic Literature Review method. Data were collected from scientific journal databases published within the last five to ten years. The results indicate significant obstacles in the abstraction indicator, where students fail to transform word problems into correct mathematical symbols. Additionally, in the algorithmic indicator, students are not yet able to arrange completion steps systematically. Such transformation errors at the initial stage cause the final solution to be invalid. In conclusion, a comprehensive strengthening of the computational thinking framework is essential for students to solve mathematical problems logically and structurally

Abstract

Design thinking has been increasingly applied in mathematics education due to its potential to promote active, contextual, and student-centered learning. However, studies that explicitly examine this approach from an epistemological perspective in mathematics education remain limited. This study aims to analyze how epistemology in mathematics education is discussed in the literature, identify the epistemological foundations underlying the application of design thinking, and examine its epistemological implications for mathematics learning. This research employed a Systematic Literature Review (SLR) following the PRISMA guidelines. Articles were collected from Google Scholar within the publication period of 2014-2024. A multi-stage screening process involving title screening, abstract screening, and full-text review resulted in 12 relevant articles for final analysis. The findings indicate that the implementation of design thinking in mathematics education is predominantly grounded in constructivist and pragmatic epistemological perspectives, which view knowledge as actively constructed through experience, reflection, and authentic problem-solving. Epistemologically, design thinking supports a shift from procedural-oriented instruction toward meaningful, collaborative, and contextual mathematics learning. The novelty of this study lies in its explicit integration of epistemological perspectives to analyze design thinking in mathematics education, offering a conceptual contribution that extends beyond previous SLR studies. Keywords: epistemology, design thinking, mathematics education, systematic literature review

Abstract

Mathematical literacy is an important ability that enables students to formulate, apply, and interpret mathematics in various real-life contexts. This study aims to analyze students' mathematical literacy skills on the material of Two-Variable Linear Equation Systems based on the gender of class VIII students of SMPN 2 Mataram. This study uses a descriptive qualitative approach. The research subjects consisted of 37 class VIII A students, then two male students and two female students were selected as research subjects based on test results. Data collection techniques were carried out through tests and interviews. Data analysis was carried out based on six indicators of mathematical literacy, namely communication, representation, mathematization, designing problem-solving strategies, use of operations and symbolic language, and reasoning and giving reasons. The results showed that both male and female students had good mathematical literacy skills, but there were differences in presenting answers. Male students tended to be stronger in oral explanations but less in written answers, while female students were more careful, systematic, and consistent in written solutions. This difference indicates that variation in ability is more evident in the accuracy and method of solution delivery. This research demonstrates the need to implement more inclusive and differentiated learning strategies.

Abstract

Penelitian ini bertujuan mendeskripsikan kemampuan pemecahan masalah matematis siswa berdasarkan disposisi matematis pada materi Sistem Persamaan Linear Dua Variabel (SPLDV). Subjek penelitian adalah sembilan siswa kelas IX-B SMP Negeri 6 Mataram yang mewakili disposisi matematis tinggi, sedang, dan rendah. Data dikumpulkan melalui angket disposisi matematis, tes kemampuan pemecahan masalah, dan wawancara, kemudian dianalisis berdasarkan empat indikator pemecahan masalah, yaitu memahami masalah, merencanakan strategi, melaksanakan strategi, dan memeriksa kembali hasil. Hasil penelitian menunjukkan bahwa siswa dengan disposisi matematis tinggi mampu menyelesaikan masalah secara runtut dan tepat pada seluruh tahapan, siswa dengan disposisi sedang cukup baik pada tahap memahami masalah dan merencanakan strategi namun belum optimal pada tahap pelaksanaan dan pemeriksaan kembali, sedangkan siswa dengan disposisi rendah mengalami kesulitan pada hampir seluruh tahapan, khususnya pelaksanaan strategi dan refleksi hasil. Temuan ini menegaskan bahwa semakin tinggi disposisi matematis siswa, semakin baik kemampuan pemecahan masalah matematisnya, sehingga pembelajaran matematika perlu menekankan pengembangan disposisi matematis selain penguasaan konsep.
