Geometric intuition is a cognitive skill that supports students in solving geometry problems, one of the more challenging branches of mathematics. This study explores students' ability to create and manipulate geometric figures when working on Higher Order Thinking Skills (HOTS) problems involving cuboids. Employing a qualitative descriptive approach, the study involved 29 eighth-grade students. Data were collected through HOTS-based problem-solving tests and validated interview protocols. Students' abilities to mentally construct and transform geometric figures were assessed using two indicators: (1) visualizing shapes based on imagination and (2) generating new geometric configurations. The findings revealed that most students were unaware of alternative geometric forms embedded within the problem context. The study concludes that students across all performance levels, from low to high, demonstrated the ability to visualize shapes based on imagination. However, only students in the medium category were able to generate a new shape in one problem, whereas those in the high category successfully created new shapes in two problems.

This study aims to develop STEAM-based mathematics learning tools integrated with a deep learning approach to enhance junior high school students’ critical thinking skills on circle material. The study employed the 4D development model consisting of Define, Design, Develop, and Disseminate stages. The developed products included a Module Implementation Plan (RPM), teaching materials, interactive learning media, Student Worksheets (LKM), and critical thinking assessment instruments. The novelty of this study lies in the systematic integration of STEAM principles and deep learning into all learning components specifically designed for circle material at the junior high school level. The validity of the tools was assessed by expert validators, while practicality was evaluated through observations of learning implementation, student activities, and student responses. Effectiveness was examined using the N-Gain test. The results showed that the developed tools were valid (mean score = 3.76), practical, and effective, with students demonstrating active participation, positive responses, and a moderate improvement in critical thinking skills (N-Gain = 0.60).

This study aims to describe students’ thinking processes in solving geometry problems through verbal expressions: verbalization, self-explanation, and oral description. The participants were three university students who were asked to work on geometry tasks containing linguistic descriptions. Data were collected through video recordings, students’ written solutions, and think-aloud notes capturing their thinking processes. Data analysis followed three stages: data reduction, data display, and conclusion drawing. The results show that all participants demonstrated strong verbalization skills by restating key information from the problem text and representing it through labels and annotations in their drawings. In the self-explanation aspect, the three students attempted to justify their solution steps through sequences of calculations, although the strategies they used were not entirely accurate. Regarding oral description, all participants were able to describe the triangle structure, point positions, and altitude lines, yet not all of them could consistently connect these visualizations with correct computational procedures. These findings affirm that students’ verbal expressions play an important role in revealing the structure of their thinking processes, especially in geometry problems that require integration between linguistic descriptions and spatial representations. Keywords: Thinking Process, Geometry, Verbalization, Self-Explanation, Oral Description

This study aims to analyze the influence of mathematical language on students’ psychological conditions in mathematics learning through a Systematic Literature Review (SLR) approach. The review examined articles published between 2015 and 2025 that discussed mathematical language, mathematical communication, and the psychological implications for learners. A total of 10 selected articles were analyzed based on research characteristics, participants, study design, and main findings. The synthesis results indicate that understanding mathematical language has a significant effect on students’ critical thinking skills, problem-solving abilities, and cognitive development. Difficulties in comprehending mathematical symbols, terminology, and structures may trigger anxiety, decreased learning motivation, and mathematics anxiety. Conversely, mastery of mathematical language enhances mathematical communication, academic self-confidence, and emotional intelligence. These findings underscore the importance of employing clear mathematical language, linguistic scaffolding, and adaptive learning strategies to foster positive cognitive and emotional learning experiences. Keywords: mathematical language, students’ psychology

This study aims to analyze students’ response patterns in geometric using the Rasch Model based on a synthesis of learning theories. The study employed a descriptive quantitative approach involving 32 eighth-grade junior high school students. The research instrument consisted of 38 true/false geometry items developed from indicators of geometric thinking processes synthesized from the theories of Piaget, Vygotsky, and Thorndike. Students’ responses were coded dichotomously, with 1 for correct answers and 0 for incorrect answers, and then analyzed using the Rasch Model. The results showed that students’ geometric thinking abilities varied, with S29P having the highest ability and S11P the lowest. The most difficult item was SL32, while the easiest item was SL1. Overall, the instrument was sufficiently able to map students’ abilities, item difficulty, and response consistency, although several items still require revision. This study offers a new approach to integrating Rasch results through a synthesis of Piaget’s, Vygotsky’s, and Thorndike’s theories, so that the measurement outcomes do not merely produce estimates of students’ abilities, but also provide pedagogical interpretations of geometric thinking patterns. Keywords: Geometric Thinking Patterns, Rasch Analysis, Synthesis of Learning Theories, Geometry

This research analyzes the thinking processes of students specializing and generalizing in solving problems related to three-dimensional geometry. The objective of this research is to clearly identify how the cognitive processes of specializing and generalizing assist students in comprehending and solving problems related to three-dimensional geometry. This study employed a descriptive qualitative method to investigate students’ problem-solving processes in three-dimensional geometry. Two ninth-grade students were selected through purposive sampling based on their mathematical abilities. Data were collected through task-based interviews and analyzed using qualitative coding to identify key problem-solving strategies and cognitive processes based on their ability to demonstrate specializing and generalizing thinking. Data were collected through geometry problem-solving tasks and unstructured interviews, and analyzed using Stacey’s cognitive framework of mathematical thinking. The result of study reveal that the students demonstrated two distinct forms of schematic representation in their problem-solving processes. Subject 1 employed a pure schematic representation and subject 2 utilized a mixed schematic representation. These two forms of representation enable students to identify patterns and apply the concepts they have learned in a broader context. The findings indicate that students exhibit distinct cognitive patterns in specializing and generalizing, with a predominant reliance on visual reasoning in spatial geometry problem-solving. While some students transition effectively between these two processes, others face difficulties in generalizing abstract concepts

This study aims to systematically review preservice teacher mathematical reasoning in solving mathematical problems from a cognitive psychology perspective. A systematic literature review was conducted on indexed journal articles published between 2020 and 2025, resulting in about forty studies relevant to mathematical reasoning, problem solving, proof, and cognitive and affective factors among university students or pre service teachers. Articles were collected from international and national databases using combinations of mathematical reasoning, university students, cognitive psychology, metacognition, beliefs, and habits of mind and then selected through identification, screening, and eligibility stages. The synthesis indicates that students’ mathematical reasoning is generally at a moderate level with weaknesses in generalization and formal proof, while procedural manipulation tends to be stronger. Working memory, metacognition, thinking dispositions, and positive beliefs about mathematics positively correlate with reasoning quality, whereas anxiety and negative beliefs hinder students’ willingness to argue and explore non routine strategies. Several instructional models such as problem based, realistic, cooperative, and reflection oriented learning supported by metacognitive scaffolding are consistently reported to improve mathematical reasoning. This review highlights the need to integrate high level mathematical task design with deliberate management of students' cognitive and affective characteristics in university mathematics education. ABSTRAK Penelitian ini mengkaji secara sistematis penalaran matematis mahasiswa dalam menyelesaikan masalah matematika melalui perspektif psikologi kognitif. Melalui systematic literature review terhadap artikel terindeks tahun 2020–2025, teridentifikasi sekitar empat puluh studi yang membahas penalaran, pemecahan masalah, pembuktian, serta faktor kognitif dan afektif pada mahasiswa atau calon guru. Pencarian dilakukan pada basis data internasional dan nasional menggunakan kombinasi kata kunci mathematical reasoning, university students, cognitive psychology, metacognition, beliefs, dan habits of mind, kemudian diseleksi melalui tahap identifikasi, penyaringan, dan kelayakan. Sintesis temuan menunjukkan bahwa penalaran matematis mahasiswa umumnya berada pada kategori sedang dengan kelemahan terutama pada kemampuan generalisasi dan penyusunan bukti formal, sedangkan kekuatan lebih tampak pada manipulasi prosedural. Faktor seperti memori kerja, metakognisi, disposisi berpikir, dan keyakinan positif terhadap matematika berkontribusi pada kualitas penalaran, sementara kecemasan dan keyakinan negatif cenderung menghambat keterlibatan dan keberanian berargumentasi. Berbagai model pembelajaran berbasis masalah, realistik, kooperatif, dan reflektif yang dipadukan dengan dukungan metakognitif konsisten dilaporkan mampu meningkatkan penalaran matematis. Kajian ini menegaskan perlunya integrasi antara desain tugas matematika tingkat tinggi dan pengelolaan aspek psikologi kognitif mahasiswa dalam pembelajaran di perguruan tinggi.
