Abstract

This study aims to describe and analyze the application of Science, Technology, Engineering, Arts, and Mathematics (STEAM) learning assisted by ikat weaving in improving the creative abilities of fifth-grade students of SDN Sonraen, South Amarasi District, Kupang Regency, East Nusa Tenggara. The research method uses a descriptive qualitative approach with 32 students divided into eight heterogeneous groups. Data were collected through observation, assessment rubrics, interviews, questionnaires, and tests, then analyzed with the stages of data reduction, data presentation, and drawing conclusions according to the Miles & Huberman model. The results show that the application of STEAM learning assisted by ikat weaving can facilitate the active involvement of students in creative, collaborative, and problem-solving thinking processes through local culture-based activities. Students are able to produce simple woven works that combine aesthetic elements with the principles of science and technology. In addition, this activity improves students' creative abilities as seen from original ideas, problem-solving skills, and appreciation of local wisdom. Thus, culture-based STEAM learning is proven to be effective in fostering creativity while strengthening students' cultural identity. The conclusion of the research using the STEAM approach assisted by ikat weaving has proven effective in building students' creative abilities while making the learning process more contextual, enjoyable, and meaningful

Abstract

Purpose of the study: This study aims to develop and evaluate a PSADS-based “Find Objects” learning media that is valid, practical, and effective in enhancing the critical thinking skills of third-grade elementary school students in mathematics. Methodology: The study employed a Research and Development approach using the ADDIE model. Data were collected through expert validation sheets, teacher and student questionnaires, classroom observations, and critical thinking tests. The test instruments were developed based on the FRISCO critical thinking indicators. Data analysis techniques included descriptive statistics, Kolmogorov–Smirnov normality tests, paired sample t-tests, and qualitative analysis using MAXQDA 2020 software. Main Findings: The PSADS-based “Find Objects” learning media was categorized as feasible to very feasible by material, instructional design, and practitioner experts. Teacher and student responses indicated a high level of practicality. Statistical analysis revealed a significant improvement in students’ critical thinking skills, with a mean score increase of 14.27 points. The paired sample t-test confirmed a significant difference between pre-test and post-test scores (p < 0.05). Novelty/Originality of this study: This study fills a research gap in elementary mathematics education, where prior studies have largely emphasized instructional models or learning outcomes without integrating concrete visual media to systematically train critical thinking processes. The novelty of this study lies in the integration of the PSADS learning stages with a “Find Objects” card-based media that engages students in structured object-search, analysis, discussion, and reflection activities, thereby emphasizing critical thinking development rather than learning outcomes alone.

Abstract

Materi Pecahan telah dipelajari sejak pendidikan dasar, khususnya Fase A. Namun, masih ditemukan adanya miskonsepsi terhadap representasi bilangan pecahan pada siswa sekolah dasar. Di sisi lain, Function Card-First Fraction Series diklaim sebagai media permainan yang didesain dengan tujuan untuk melatih kemampuan dan kreativitas siswa dalam materi representasi pecahan. Oleh karena itu, penelitian ini bertujuan untuk menguji pengaruh Function Card-First Fraction Series terhadap kemampuan dan kreativitas siswa SD dalam merepresentasikan bilangan pecahan. Penelitian kuantitatif jenis quasi experiment ini menggunakan desain One-Group Pretest Posttest Design. Metode pengumpulan data menggunakan metode tes dengan intrumen berupa tes uraian untuk mengukur kemampuan dan kreativitas siswa dalam merepresentasikan pecahan. Hasil penelitian menunjukkan bahwa penggunaan Function Card-First Fraction Series secara signifikan dapat meningkatkan kemampuan dan kreativitas siswa SD dalam representasi pecahan menjadi lebih baik. Peningkatan signifikan pada aspek kreativitas terlihat dari unsur fluency, flexibility, dan originality. Berdasarkan simpulan tersebut, maka disarankan bagi guru untuk menggunakan media Function Card-First Fraction Series sebagai upaya dalam memfasilitasi siswa belajar representasi bilangan pecahan agar tidak hanya mampu namun juga memiliki kreativitas dalam merepresentasikan bilangan pecahan.

Abstract

Science learning in elementary school plays an important role in developing students’ learning interest and critical thinking skills. However, students often experience difficulties in understanding abstract concepts such as vertebrate and invertebrate classification due to limited interactive learning media. This study aimed to develop and evaluate the feasibility and effectiveness of an integrated learning medium called the “VEIN” (Vertebrate–Invertebrate) flashcards and 3D pop-up book to increase students’ learning interest and critical thinking skills. This research employed a Research and Development (R&D) design conducted in two elementary schools in Jambi City involving 16 third-grade students. Data were collected through observation, interviews, questionnaires, documentation, and critical thinking tests, and analyzed quantitatively using percentage analysis. The results showed that 62.5% of students were categorized as having high learning interest, 25% medium, and 12.5% low. Critical thinking skills improved particularly in interpretation (68.75%) and analysis (62.5%) indicators, while inference reached 43.75% in the medium category. These findings indicate that the VEIN media effectively promotes active engagement, facilitates concrete conceptual understanding, and supports the gradual development of critical thinking skills. In conclusion, the VEIN flashcards and pop-up book are feasible, practical, and effective as innovative media to enhance learning interest and critical thinking in integrated elementary science learning

Abstract

This study aims to develop and examine the theoretical feasibility of Karmatika (Mathematics Karuta), a card-based learning medium designed for geometry instruction in junior high schools. The study employed a Research and Development (R&D) approach using the 4D development model (Define, Design, Develop, Disseminate), limited to the Develop stage, particularly expert appraisal. Data were collected using validation sheets completed by media and material experts on a four-point Likert scale. The findings revealed that the Karmatika media achieved a validity score of 94.4% from media experts, categorized as “Highly Valid,” and 83.3% from material experts, categorized as “Valid.” These results indicate that the Karmatika card media is theoretically feasible for use in mathematics learning, particularly in geometry instruction. This study contributes an innovative mathematics learning medium adapted from the traditional Japanese karuta game and designed to align with the cognitive development characteristics of junior high school students. BAHASA INDONESIA ABSTRACT: Penelitian ini bertujuan untuk mengembangkan dan menguji kelayakan teoretis media pembelajaran berbasis kartu Karmatika (Mathematics Karuta) pada materi geometri untuk siswa sekolah menengah pertama.
