Abstract

Kemampuan Berpikir Tingkat Tinggi (HOTS) siswa dalam pembelajaran matematika masih rendah, khususnya pada kemampuan menganalisis, mengevaluasi, dan mencipta. Penelitian ini bertujuan menguji pengaruh Problem-Based Learning yang diperkaya dengan scaffolding metakognitif (PBL-MS) terhadap peningkatan HOTS siswa. Penelitian kuasi-eksperimental dengan desain pretest–posttest control group melibatkan 60 siswa kelas X SMA Negeri 15 Bandung yang dibagi ke dalam kelompok eksperimen (PBL-MS) dan kontrol (PBL). Data kemampuan HOTS dikumpulkan melalui tes tertulis berbentuk esai berdasarkan taksonomi Bloom revisi. Hasil penelitian menunjukkan bahwa peningkatan HOTS siswa pada kelompok PBL-MS berada pada kategori sedang (N-Gain = 0,51), sedangkan kelompok PBL berada pada kategori rendah (N-Gain = 0,30), dengan perbedaan yang signifikan (Sig. 2-tailed < 0,05). Temuan ini menunjukkan bahwa integrasi scaffolding metakognitif dalam PBL lebih efektif dalam meningkatkan kemampuan HOTS siswa. Students’ Higher-Order Thinking Skills (HOTS) in mathematics learning remain low, particularly in analyzing, evaluating, and creating skills, indicating the need for instructional strategies that can better support students’ thinking processes. This study aimed to examine the effect of Problem-Based Learning enriched with metacognitive scaffolding (PBL-MS) on improving students’ HOTS. A quasi-experimental study with a pretest–posttest control group design was conducted at SMA Negeri 15 Bandung, involving 60 tenth-grade students divided into an experimental group (PBL-MS) and a control group (PBL). HOTS data were collected using an essay-based written test developed based on the revised Bloom’s taxonomy, covering analyzing, evaluating, and creating indicators. The results showed that the improvement in HOTS of students taught using PBL-MS was in the moderate category (N-Gain = 0.51), while students taught using PBL alone achieved a low category (N-Gain = 0.30). Statistical analysis indicated a significant difference between the two groups (Sig. 2-tailed < 0.05). These findings indicate that integrating metacognitive scaffolding into Problem-Based Learning provides a stronger effect on improving students’ higher-order thinking skills.

Abstract

Pemecahan masalah geometri menuntut integrasi antara kemampuan kognitif dan aspek afektif, khususnya efikasi diri. Penelitian ini bertujuan mengidentifikasi profil efikasi diri mahasiswa pendidikan matematika serta menganalisis pengaruhnya terhadap proses pemecahan masalah geometri berdasarkan tahapan Polya. Menggunakan desain studi kasus kualitatif, penelitian ini melibatkan 33 mahasiswa. Data dikumpulkan melalui skala efikasi diri, tes geometri berbasis empat tahap Polya, dan wawancara semi-terstruktur dengan subjek yang merepresentasikan tingkat efikasi diri tinggi, sedang, dan rendah. Hasil penelitian mengungkap tiga profil berbeda: mahasiswa dengan efikasi diri tinggi mampu menunjukkan pemahaman mendalam hingga evaluasi reflektif; mahasiswa dengan efikasi diri sedang mampu melaksanakan prosedur namun tidak stabil pada tahap perencanaan dan evaluasi; sedangkan mahasiswa dengan efikasi diri rendah kesulitan dalam merumuskan strategi dan verifikasi hasil. Temuan ini menegaskan bahwa efikasi diri berpengaruh signifikan terhadap kualitas pemecahan masalah geometri, sehingga perlu diintegrasikan dalam perancangan pembelajaran matematika yang komprehensif. Geometric problem-solving demands the integration of cognitive abilities and affective readiness, notably self-efficacy. This study aims to identify the self-efficacy profiles of mathematics education students and analyze their influence on the geometric problem-solving process based on Polya’s stages. Employing a qualitative case study design, the research involved 33 students. Data were collected through a self-efficacy scale, geometric problem-solving tests structured according to Polya’s four stages, and semi-structured interviews with subjects representing high, moderate, and low self-efficacy levels. The findings reveal three distinct profiles: students with high self-efficacy demonstrate deep understanding followed by reflective evaluation; those with moderate self-efficacy execute procedures correctly but show instability during the planning and evaluation stages; while students with low self-efficacy struggle with strategy formulation and result verification. These findings underscore that self-efficacy significantly influences the quality of geometric problem-solving, highlighting the necessity of integrating affective factors into the design of comprehensive mathematics instruction.

Abstract

Pikiran kreatif merupakan kompetensi kunci dalam pembelajaran geometri, yang sering melibatkan pemecahan masalah yang tidak rutin dan secara visual kompleks, namun banyak siswa mengalami kesulitan dalam mengembangkan strategi pemecahan masalah. Peningkatan penggunaan kecerdasan buatan generatif seperti ChatGPT menawarkan peluang pedagogis baru, namun perannya dalam mendukung pemikiran kreatif matematis masih belum jelas. Studi ini bertujuan untuk mengkaji bagaimana keterkaitan pembelajaran yang didukung ChatGPT terhadap pemikiran kreatif matematis siswa dalam geometri dan menganalisis karakteristik pemecahan masalah siswa saat didukung oleh AI. Studi kasus kualitatif dilakukan dengan 29 siswa kelas tujuh dari SMP di Kampar. Data dikumpulkan melalui Tes Kemampuan Berpikir Kreatif Matematika dengan empat soal geometri non-rutin, observasi kelas, dan analisis tanggapan tertulis siswa, yang dievaluasi menggunakan indikator berpikir kreatif matematika. Temuan menunjukkan bahwa berpikir kreatif siswa berada pada tingkat sedang, dengan ChatGPT paling efektif dalam mendukung elaborasi, sementara fleksibilitas dan orisinalitas tetap relatif lemah. Kesalahan utama terjadi pada tahap keterampilan transformasi dan proses, terutama dalam tugas visual-spasial. ChatGPT berfungsi sebagai scaffolding prosedural dan elaboratif rather than katalisator untuk pemikiran divergen, menyoroti kebutuhan akan integrasi AI yang terarah dan reflektif dalam pembelajaran geometri. Creative thinking is a key competency in geometry learning, which often involves solving non-routine and visually complex problems, yet many students struggle to develop problem-solving strategies. The increased use of generative artificial intelligence such as ChatGPT offers new pedagogical opportunities, but its role in supporting mathematical creative thinking remains unclear. This study aims to examine how ChatGPT-supported learning relates to students' mathematical creative thinking in geometry and to analyse the characteristics of students' problem solving when supported by AI. A qualitative case study was conducted with 29 seventh-grade students from a secondary school in Kampar. Data were collected through a Mathematical Creative Thinking Ability Test with four non-routine geometry questions, classroom observations, and analysis of students' written responses, which were evaluated using indicators of mathematical creative thinking. Findings indicate that students' creative thinking is at a moderate level, with ChatGPT most effective in supporting elaboration, while flexibility and originality remain relatively weak. The main errors occurred at the transformation and process skill stages, especially in visual-spatial tasks. ChatGPT functioned as procedural and elaborative scaffolding rather than a catalyst for divergent thinking, highlighting the need for targeted and reflective AI integration in geometry learning.

Abstract

Penerapan Project-Based Learning (PjBL) berpotensi mengembangkan berpikir kritis, namun integrasi masalah nyata seperti mitigasi bencana masih jarang dilakukan. Penelitian ini bertujuan menguji keefektifan proyek mitigasi filter air berbasis STEAM dalam menumbuhkan kemampuan berpikir kritis siswa. Menggunakan desain eksperimen murni posttest-only control group, penelitian ini melibatkan 58 siswa kelas VII SMP Negeri 3 Kembang Jepara yang dipilih melalui cluster random sampling. Kelompok eksperimen menerapkan proyek STEAM, sementara kelompok kontrol menggunakan pembelajaran konvensional. Data dikumpulkan melalui tes hasil belajar dan angket respons, lalu dianalisis menggunakan uji independent t-test. Hasil penelitian menunjukkan bahwa kemampuan berpikir kritis siswa pada kelompok eksperimen secara signifikan lebih baik dibandingkan kelompok kontrol. Temuan ini menegaskan bahwa proyek mitigasi filter air berbasis STEAM efektif mengembangkan berpikir kritis serta keterampilan abad ke-21 (kreativitas, kolaborasi, dan komunikasi). Integrasi matematika dalam konteks dunia nyata melalui proyek STEAM menjadi strategi krusial untuk menumbuhkan kepedulian siswa terhadap isu mitigasi bencana. While Project-Based Learning (PjBL) is recognized for its potential to develop students' critical thinking, the integration of real-world contexts, particularly disaster mitigation, remains underexplored. This study aims to evaluate the effectiveness of a STEAM-based water filter mitigation project in fostering students' critical thinking skills. Employing a true experimental posttest-only control group design, the study involved 58 seventh-grade students from SMP Negeri 3 Kembang Jepara, selected via cluster random sampling. The experimental group implemented the STEAM project, while the control group received teacher-centered conventional instruction. Data were collected through achievement tests and student response questionnaires, followed by independent t-test analysis. The findings reveal that students engaged in the STEAM-based project demonstrated significantly higher critical thinking skills than those in the conventional group. This study confirms that STEAM-based water filter mitigation projects effectively develop critical thinking and reinforce 21st-century skills, including creativity, collaboration, and communication. Furthermore, integrating mathematics into real-world contexts through STEAM serves as a crucial strategy to enhance students' awareness of disaster mitigation issues.

Abstract

Kemampuan pemecahan masalah dan penalaran matematis adalah aspek krusial dalam pembelajaran matematika. Namun, ketergantungan siswa pada teknologi dalam menyelesaikan soal justru memicu penurunan kemampuan penalaran tersebut. Penelitian ini bertujuan menganalisis kemampuan penalaran matematis siswa SMK menggunakan aplikasi Math Expert. Melalui metode campuran (mixed method) tipe embedded design, penelitian ini melibatkan 86 siswa kelas X SMK di Cianjur yang terbagi ke dalam kelas eksperimen dan kontrol. Data dikumpulkan melalui kuesioner, observasi, wawancara, dan instrumen tes penalaran matematis berdasarkan standar NCTM. Hasil penelitian menunjukkan perbedaan signifikan pada enam indikator penalaran NCTM, yang meliputi kemampuan: justifikasi kesimpulan; pengujian dugaan matematis; evaluasi argumen; variasi metode solusi; pengorganisasian data masalah; serta penilaian terhadap hasil kerja orang lain. Secara keseluruhan, penggunaan aplikasi Math Expert terbukti efektif meningkatkan kemampuan penalaran matematis siswa SMK, meskipun tingkat peningkatan pada setiap indikator bervariasi. Problem-solving and mathematical reasoning are crucial aspects of mathematics education. However, students' over-reliance on technology for problem-solving has triggered a decline in these specific reasoning abilities. This study aims to analyze the mathematical reasoning skills of vocational high school (SMK) students through the implementation of the Math Expert application. Utilizing a mixed-methods approach with an embedded design, the research involved 86 tenth-grade students in Cianjur, divided into experimental and control groups. Data were collected via questionnaires, observations, interviews, and mathematical reasoning tests based on NCTM standards. The findings indicate significant differences across six NCTM reasoning indicators, including the ability to: justify conclusions; test mathematical conjectures; evaluate arguments; employ diverse solution methods; organize situational problem data; and assess the work of others. Overall, the results demonstrate that the Math Expert application effectively enhances students' mathematical reasoning skills, although the degree of improvement varies across the specific indicators.

Abstract

Penelitian ini mengkaji bagaimana mahasiswa mengalami dan memaknai tahapan pemecahan masalah Polya saat mengerjakan tugas geometri dalam lingkungan electronic Problem-Based Learning (e-PBL) yang diimplementasikan melalui sistem manajemen pembelajaran berbasis Moodle yang dikustomisasi. Penelitian ini menggunakan desain deskriptif kualitatif dengan sumber data berupa artefak pemecahan masalah tertulis, wawancara semi-terstruktur, dan jejak digital selama e-PBL. Data dianalisis menggunakan analisis tematik Braun dan Clarke dengan pengodean deduktif berdasarkan empat tahap Polya dan pengodean induktif untuk menangkap pola penalaran yang muncul. Hasil penelitian menunjukkan bahwa pemecahan masalah berlangsung secara dinamis dan rekursif. Tahap memahami dan merencanakan melibatkan penafsiran ulang representasi multimodal, sedangkan tahap pelaksanaan ditandai oleh pergeseran representasi yang memperjelas konsep. Prompt reflektif dalam e-PBL mendukung deteksi kesalahan dan penguatan konsep, serta menegaskan peran tahap evaluasi. This study examines how students experience and interpret Polya’s problem-solving stages while working on geometry tasks in an electronic Problem-Based Learning (e-PBL) environment implemented through a customized Moodle based learning management system. Using a qualitative descriptive design, data were collected from written problem-solving artefacts, semi-structured interviews, and digital traces generated during e-PBL activities. The data were analyzed using thematic analysis following Braun and Clarke, combining deductive coding based on Polya’s four stages with inductive coding to capture emerging reasoning patterns. The findings indicate that problem-solving is enacted as a dynamic and recursive process rather than a linear sequence. Understanding and planning involve repeated reinterpretation of multimodal representations, while execution is characterized by representational shifts that support conceptual clarity. Reflective prompts in e-PBL facilitate error detection and conceptual consolidation, highlighting the importance of the evaluative stage.

Abstract

Pembelajaran matematika memerlukan pendekatan relevan untuk mengembangkan kemampuan pemecahan masalah kompleks. Penelitian ini bertujuan mengevaluasi efektivitas pendekatan Mathematics in Context (MiC) terhadap kemampuan pemecahan masalah matematika siswa kelas V di tiga sekolah dasar Kabupaten Pinrang. Penelitian dilakukan sebanyak 17 pertemuan menggunakan bahan ajar dan panduan guru yang telah divalidasi ahli. Data dikumpulkan melalui instrumen pretes dan postes yang mengukur lima aspek pemecahan masalah: analisis, desain, eksplorasi, implementasi, dan verifikasi. Hasil analisis menunjukkan adanya perbedaan rata-rata kemampuan siswa yang signifikan sebelum dan sesudah perlakuan di ketiga sekolah. Berdasarkan skor N-Gain, pendekatan MiC terbukti cukup efektif meningkatkan kemampuan pemecahan masalah siswa; aspek analisis, desain, dan eksplorasi berada pada kategori sedang, sementara aspek implementasi dan verifikasi berada pada kategori rendah. Temuan ini menyimpulkan bahwa pendekatan MiC efektif dalam membantu siswa memahami dan merancang strategi penyelesaian, namun kurang optimal dalam meningkatkan kemampuan prosedur penyelesaian (implementasi) dan verifikasi jawaban. Mathematics education aims to cultivate students' ability to solve complex mathematical problems, necessitating the use of relevant pedagogical approaches. This study evaluates the effectiveness of the Mathematics in Context (MiC) approach on the mathematical problem-solving skills of fifth-grade students across three elementary schools in Pinrang Regency. The intervention was conducted over seventeen sessions using MiC-based instructional materials and teacher guides validated by experts. Data were collected via pre-test and post-test instruments measuring five dimensions of problem-solving: analysis, design, exploration, implementation, and verification. Analysis revealed a significant difference in mean problem-solving scores before and after the MiC intervention across all schools. N-Gain analysis results indicate that the MiC approach is moderately effective in enhancing student performance; specifically, the analysis, design, and exploration aspects reached the "medium" category, while implementation and verification remained in the "low" category. These findings suggest that while the MiC approach effectively supports students in understanding and designing problem-solving strategies, it is less optimal in improving procedural execution and solution verification.

Abstract

Transformasi digital menuntut penguasaan berpikir komputasional (computational thinking/CT) sebagai fondasi utama pendidikan matematika. Namun, keterampilan penalaran logis siswa di Kabupaten Sumedang masih rendah karena pembelajaran belum mengoptimalkan kearifan lokal. Penelitian ini bertujuan menganalisis profil awal kemampuan CT siswa pada aspek dekomposisi, pengenalan pola, abstraksi, dan algoritma, serta mengidentifikasi kebutuhan terhadap media interaktif berbasis Scratch. Menggunakan model pengembangan ADDIE yang dibatasi pada tahap analisis, penelitian ini melibatkan 32 siswa kelas VIII dan tiga guru matematika di sebuah SMP Negeri di Sumedang. Data dihimpun melalui tes CT, kuesioner, wawancara, dan dokumentasi. Temuan menunjukkan kemampuan CT siswa masih rendah, terutama pada aspek abstraksi (18,98%) dan algoritma (16,01%). Hasil analisis kebutuhan menunjukkan tingkat urgensi yang sangat tinggi (83%) bagi pengembangan media berbasis Scratch terintegrasi kearifan lokal Sumedang sebagai sarana penguatan penalaran komputasional dan motivasi belajar siswa. Digital transformation necessitates the mastery of computational thinking (CT) as a fundamental pillar of mathematics education. However, students' logical reasoning skills in Sumedang Regency remain underdeveloped, largely because instructional methods have yet to optimize the use of local wisdom. This study aims to analyze the initial CT profiles of students, focusing on decomposition, pattern recognition, abstraction, and algorithms, and to identify the necessity for Scratch-based interactive learning media. Adopting the ADDIE development model, limited to the analysis phase, the study involved 32 eighth-grade students and three mathematics teachers at a public junior high school in Sumedang. Data were gathered through CT competency tests, questionnaires, interviews, and documentation. The findings reveal that students' CT skills are low, particularly in abstraction (18.98%) and algorithms (16.01%). Furthermore, the needs analysis indicates a high level of urgency (83%) for developing Scratch-based media integrated with Sumedang’s local wisdom as a cognitive tool to strengthen computational reasoning and enhance student motivation.
