The concept of mathematical material is still not fully embedded in students' schemes, this means that errors occur in constructing the concept. This research aims to describe the actual situation regarding pseudo-construction errors that occur at the APOS (Action, Process, Object, and Scheme) stages. This research involved 28 students in class VIII A of SMPN 2 Silo Jember as subjects through problem solving test to get an comprehensive information about occuring errors. Then by the purposive sampling and snowball sampling techniques, two subjects are choosen to explore in depth through interview. The data valiadation is guarantee through the member check process. Data analysis includie data condensation, data presentation, and concluding. The results of the research are that pseudo-construction errors occur at every stage of APOS which results in the concept not being fully constructed in the student's scheme. As a recommendation, developing a mathematics learning model based on APOS theory to minimize the error is needed such that the concepts will be well and completely constructed in students' schemes. Konsep materi matematika masih belum sepenuhnya tertanam dalam skema siswa. Hal ini menunjukkan bahwa terjadi kesalahan dalam mengkonstruk konsep. Penelitian ini bertujuan untuk menggambarkan atau mendeskripsikan keadaan yang sebenarnya terkait kesalahan konstruksi semu yang terjadi pada tahapan APOS (Aksi, Proses, Objek, dan Skema). Penelitian ini melibatkan 28 siswa kelas VIII A SMPN 2 Silo Jember sebagai subjek melalui tes pemecahan masalah untuk mendapatkan informasi komprehensif tentang kesalahan yang terjadi.

One of the cultural behaviors of local wisdom that is starting to disappear is related to how manage the "garbage". Several communities still throw garbage out of place, such as in the river. On the other hand, the effects of this waste that was disposed of carelessly are very long-term for human health and also the environment. This culture is eventually emulated by their children and grandchildren who are still in school. For this reason, community awareness regarding waste needs to be directed, one of which is the management of a community waste bank. In Tegalsari Village, Ambulu Jember there is one Cipta Mandiri Waste Bank that has been operating for the last 3 years. The Waste Bank activity went quite well, but less than 20% of the community participated, especially young people and children who were less interested. So that the empowerment of the Waste Bank needs to be supported in order to be able to pass down the local culture of being aware of waste, especially for elementary school students through the socialization and education of ethnomathematics worksheets in the elementary school. The results of the activity showed that 78% of students wanted to take part in the waste bank around their homes and they enjoy learning with ethnomathematics worksheets about garbage.

Students' difficulties in visualizing geometric objects often trigger various errors in problem-solving. Although mental imagery has an important function in clarifying the shape, position, and relationships between geometric elements, research specifically examining its relationship with student error types is still limited. This study aims to describe the relationship between mental imagery and student error types in solving geometric problems. The research method used is a qualitative approach with a case study design. The research subjects consisted of three mathematics education students selected based on the variety of errors they made. Data was collected through geometry tests, observations, think-alouds, and in-depth interviews. The results showed that inaccurate or incomplete mental imagery led to the emergence of visual representation errors, conceptual errors, procedural errors, and calculation errors. Mental imagery that is not integrated with conceptual and procedural understanding causes students to misinterpret problems. The contribution of this study emphasizes the importance of strengthening visualization skills and integrating geometric concepts in learning to minimize students' cognitive errors.

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.

This study aimed to describe the role of working memory, mathematics anxiety, and mathematical communication skills in mathematical problem solving. This study was based on the view that successful problem solving depended not only on mastery of concepts and procedures, but also on cognitive and affective factors, and students' ability to communicate their mathematical ideas. The used method was a systematic literature review of 20 Scopus-indexed international journal articles discussing the relationship between working memory, mathematics anxiety, mathematical communication, and problem solving. The results of the study indicate that working memory is positively related to mathematical problem solving and mathematical communication skills. Students with high working memory tend to be better able to understand problem texts, retain important information, choose strategies, and re-explain the solution process orally and in writing. Conversely, mathematics anxiety is negatively related to problem solving; high anxiety disrupts working memory function and reduces students' courage to participate in mathematical communication. Overall, mathematical problem solving is simultaneously influenced by working memory, mathematics anxiety, and mathematical communication skills. Therefore, mathematics learning needs to be designed by considering working memory load, anxiety management, and strengthening mathematical communication activities in the classroom.

This study aims to analyze the various problems experienced by students in learning geometry and to examine improvement efforts that can enhance students’ learning motivation. Based on the results of the study, it was found that many students experience difficulties in understanding basic geometry concepts. These difficulties are reflected in students’ low ability to recognize shapes, understand relationships between geometric figures, and apply formulas correctly in problem-solving. In addition, students often make errors in using principles and procedures for solving geometry problems. Another dominant difficulty is students’ limited ability to understand word problems, which makes it difficult for them to translate problems into mathematical forms. The factors causing these learning difficulties originate not only from cognitive aspects, but are also influenced by emotional factors, the learning environment, and students’ low motivation in participating in the learning process. Therefore, effective improvement efforts are needed, such as strengthening mathematical communication, implementing active learning methods, and providing opportunities for students to explore and express mathematical ideas independently. With appropriate and engaging learning strategies, students’ learning motivation can increase, leading to a better understanding of geometry concepts and improved learning outcomes.

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.
