Critical thinking is one of the high-level thinking. Mathematics learning in globalization era usually uses critical thinking in solving problems. Mathematics is always thought as the difficult one to be learnt. This research will describe students critical thinking profile in solving the function of compositions through collaborative learning. This reseach can be used as the reference for teachers to recognize students critical thinking profile in their class, and also it can be used to motivate students to enhance their critical thinking ability. The critical thinking criterias are focus, reason, inference, situation, and overview. That criterias include eleven indicators. The type of collaborative learning in this research is Learning Together (LT). This research is descriptive with qualitative approach. The data were collected by documentation, observation, test, and interview. The subjects of this research are six students who are two high-achiever students, two medium-achiever students, and two low-achiever students from one of senior high school at Jember. High-achiever students can achieve all criterias of critical thinking and they dominate the role in learning and teaching activity. The medium-achiever students only fulfill focus in the first and second indicator, reason in the second, and inference, situation, clarity, and overview in the second indicator and also can join in the collaborative learning. While, the low-achiever students can only look to other students without get engaged actively in collaborative learning and only achieve focus in the first and second indicators of situation.

Kemampuan berpikir spasial merupakan aspek penting dimiliki siswa dalam menyelesaikan soal objek tiga dimensi. Siswa yang tidak mampu berpikir spasial dengan baik akan mengalami kesulitan, hal tersebut juga dapat dialami oleh siswa tunagrahita. Penelitian ini adalah penelitian kualitatif dengan data utama proses berpikir spasial siswa tunagrahita. Pemilihan subjek berdasarkan jenjang kelas yang sudah mempelajari materi kubus dan mampu membaca serta menulis sehingga subjek penelitian terdiri dari satu orang siswa. Tujuan dari penelitian ini adalah mengetahui proses berpikir siswa tunagrahita dalam memahami materi kubus berbantuan alat peraga. Penelitian ini dilakukan karena siswa tunagrahita memiliki keterbatasan intelektual dalam memahami konsep geometri yang abstrak, sehingga diperlukan analisis proses berpikir spasial dengan bantuan alat peraga untuk mengoptimalkan kemampuan visualisasi dan pemahaman matematis mereka. Indikator spasial pada penelitian ini meliputi visualisasi spasial, orientasi spasial dan relasi spasial. Hasil penelitian menunjukkan bahwa subjek terpilih tergolong dalam kategori tunagrahita sedang berdasarkan tes psikologi. Proses berpikir spasial siswa tunagrahita sedang dapat dilihat bahwa siswa menjawab soal dengan benar setelah mengerjakan soal dengan tipe yang sama secara berulang. Rekomendasi penelitian selanjutnya yaitu melakukan kajian serupa pada kategori siswa tunagrahita lainnya dengan memastikan validasi kategori subjek untuk menyesuaikan tingkat kesulitan soal, serta memberikan contoh gambar berpetak atau garis putus-putus pada lembar jawaban untuk memudahkan siswa menebali.

Penelitian ini bertujuan untuk meninjau ulang berpikir kreatif siswa dalam menyelesaikan masalah geometri melalui perspektif level berpikir van Hiele. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan melibatkan 28 siswa kelas IV sekolah dasar. Dari jumlah tersebut, dipilih enam subjek secara purposive untuk dianalisis secara mendalam berdasarkan level berpikir van Hiele. Data dikumpulkan melalui tes kemampuan geometri, tugas berpikir kreatif berbasis tangram, dan wawancara semi-terstruktur. Analisis data dilakukan secara kualitatif melalui reduksi data, penyajian data, dan penarikan kesimpulan, dengan fokus pada indikator fluency, flexibility, dan originality. Hasil penelitian menunjukkan bahwa kemampuan berpikir kreatif siswa tidak berkembang secara linier seiring dengan peningkatan level berpikir van Hiele. Siswa pada level yang lebih tinggi tidak selalu menunjukkan tingkat kreativitas yang lebih baik, khususnya pada aspek originality. Sebaliknya, siswa pada level yang lebih rendah masih mampu menunjukkan kemampuan fluency dan flexibility melalui eksplorasi variasi solusi. Temuan ini mengindikasikan bahwa kreativitas dalam geometri lebih banyak berkembang pada tahap eksploratif dan belum sepenuhnya mencapai tahap generatif. Penelitian ini menyimpulkan bahwa berpikir kreatif dalam geometri tidak dapat dipahami semata-mata sebagai hasil dari perkembangan kognitif geometris, tetapi sebagai proses dinamis yang melibatkan interaksi antara pemahaman konsep, pengalaman manipulatif, dan strategi eksplorasi. Oleh karena itu, pembelajaran geometri perlu dirancang untuk tidak hanya meningkatkan level berpikir, tetapi juga mendorong perkembangan kreativitas melalui tugas-tugas terbuka dan eksploratif.

Low nutritional literacy and health numeracy in rural families have the potential to impact the quality of food choices and daily cooking practices. Exploratory interviews conducted in March 2025 with mothers participating in the Community-Based Nutritional Research Center (TBM) in Serut Village revealed limitations in understanding nutritional composition, serving sizes, and budget-based menu planning. This situation prompted the need for interventions to improve mothers' nutritional knowledge, attitudes, and practices (KAP) and to strengthen children's health numeracy. The “Healthy Menu, Right Numbers” community program was implemented through six meetings using a community-based participatory approach (CBPA) for two target groups: mothers (n=10) and preschool–elementary school children (n=50). The materials covered balanced nutrition, label literacy, menu preparation using local ingredients, and contextual numeracy (portion calculation, serving sizes, budget), with CALGIBRA as a simple calculation tool. The evaluation used a descriptive pre-post design without inferential testing. In the mother group (n=10), the mean score increased from 29.0±2.05 to 29.4±2.63 (Δ=+0.4; maximum 32), with 6 mothers improving and 4 decreasing slightly. In the child group (7 groups), three groups improved, three remained stable, and one decreased. The findings are descriptive and contextual, showing mild but consistent improvements in mothers and strengthening of contextual numeracy in children. Sustainability focuses on monthly monitoring and micro-coaching based on kitchen cases, with CALGIBRA as an innovation that supports independent numeracy practice.

ABSTRACT Geometry is considered one of the most difficult topics in mathematics because it requires students to simultaneously master visualization skills, spatial representation, and abstract conceptual understanding. This condition indicates the need for an instrument capable of measuring students’ visual-spatial abilities more comprehensively. This study aimed to develop a geometry test instrument based on Hass theory, which includes conceptualization, imagination, problem solving, and pattern recognition. The study employed a qualitative approach through several stages, including indicator formulation, item development, expert validation, instrument revision, and finalization of the instrument. The validation process involved two validators consisting of one geometry lecturer and one mathematics teacher who assessed the appropriateness of the content, indicators, language, and item construction. The results showed that the developed instrument consisted of seven visual-spatial ability-based test items and achieved a very high validity level with an average validation score of 5. The resulting instrument was considered capable of measuring students’ geometry abilities more systematically, particularly in the aspects of visualization and spatial reasoning. The novelty of this study lies in the development of a geometry instrument based on Hass theory integrated into the measurement of students’ visual-spatial abilities. This study is expected to serve as a reference for the development of geometry learning evaluation based on spatial abilities and Higher Order Thinking Skills (HOTS). ABSTRAK Geometri merupakan salah satu materi matematika yang masih dianggap sulit oleh peserta didik karena menuntut kemampuan visualisasi, representasi ruang, dan pemahaman konsep abstrak secara bersamaan. Kondisi tersebut menunjukkan perlunya instrumen yang mampu mengukur kemampuan visual spasial peserta didik secara lebih komprehensif. Penelitian ini bertujuan mengembangkan instrumen tes kemampuan geometri berbasis teori Hass yang meliputi pengkonsepan, pengimajinasian, penyelesaian masalah, dan penemuan pola. Penelitian menggunakan pendekatan kualitatif dengan tahapan penyusunan indikator, pengembangan butir soal, validasi ahli, revisi instrumen, dan penetapan instrumen final. Proses validasi dilakukan oleh dua validator yang terdiri atas satu dosen geometri dan satu guru matematika untuk menilai kesesuaian materi, indikator, bahasa, dan konstruksi soal. Hasil penelitian menunjukkan bahwa instrumen yang dikembangkan terdiri atas tujuh butir soal berbasis kemampuan visual spasial dan memperoleh tingkat validitas sangat tinggi dengan rata-rata skor validasi sebesar 5. Instrumen yang dihasilkan dinilai mampu mengukur kemampuan geometri peserta didik secara lebih sistematis, terutama pada aspek visualisasi dan penalaran spasial. Novelty penelitian ini terletak pada pengembangan instrumen geometri berbasis teori Hass yang terintegrasi dalam pengukuran kemampuan visual spasial peserta didik. Penelitian ini diharapkan dapat menjadi referensi dalam pengembangan evaluasi pembelajaran geometri berbasis kemampuan spasial dan Higher Order Thinking Skills (HOTS).

Purpose: This study examines how geometry task management shapes students’ spatial structuring when solving Pythagorean Theorem problems through tangram-based tasks. Method: This study employed a qualitative case study design involving six eighth-grade students (aged 13–14) from a public junior high school. The participants were purposively selected to represent diverse levels of classroom participation. Data were collected across three classroom sessions through students’ work artifacts, classroom interaction transcripts, and observation notes. Data were analyzed using a qualitative interpretative approach involving iterative coding and cross-case comparison to identify patterns of spatial structuring, particularly in relation to part–whole coordination, recognition of invariant properties, and reconfiguration strategies. Findings: The analysis indicates that geometry task management shapes students’ spatial structuring through geometric reconfiguration and increasing attention to part–whole relationships. Students’ reasoning evolves from visual manipulation toward more relational forms of understanding as tasks are sequenced and supported through teacher questioning; for example, some students initially relied on visual fitting strategies but later justified their rearrangements by referring to equal lengths and area equivalence after teacher prompts. The results indicate that spatial reasoning emerges through interaction with representations and is influenced by how instructional tasks direct students’ attention to invariant geometric relationships. Significance: This study contributes to mathematics education by showing how spatial structuring can be understood as a pedagogically supported process shaped through geometry task management. The findings highlight the importance of task sequencing and teacher guidance in supporting students’ spatial reasoning in learning the Pythagorean Theorem.

The Merdeka Curriculum provides the foundational framework for reforms in mathematics education, emphasizing adaptability, learner-centered approaches, and the integration of real-life contexts to develop critical thinking abilities. The primary objective of this study is to examine how the Merdeka Curriculum is implemented within mathematics education and to assess its connection with students’ critical thinking skills. A systematic literature review was conducted using the PRISMA methodology, encompassing the phases of identification, screening, eligibility assessment, and final inclusion of articles published between 2021 and 2026. The data, sourced from Google Scholar, were analyzed narratively to uncover implementation patterns, enabling factors, and prevailing obstacles. The findings reveal that the application of the Merdeka Curriculum in mathematics instruction primarily occurs through active learning strategies, including Project-Based Learning, Problem-Based Learning, differentiated instruction, and the utilization of contextual teaching resources such as worksheets and ethnomathematics-based modules. The results further demonstrate an enhancement in students’ critical thinking capabilities, reflected in improved analytical, evaluative, inferential, and problem-solving skills. Nevertheless, successful implementation remains contingent on several factors, namely teachers’ pedagogical preparedness, constraints related to instructional time, and their comprehension of the curriculum’s structure. The discussion highlights that the Merdeka Curriculum holds considerable promise for fostering critical thinking, provided it is accompanied by methodical planning and consistent execution. The study concludes that while the Merdeka Curriculum is both relevant and effective in improving students’ critical thinking in mathematics, it necessitates the reinforcement of teacher competencies and the refinement of classroom implementation practices.
