Abstract

Pembelajaran abad ke-21 menekankan pentingnya mengembangkan keterampilan siswa, termasuk dalam mata pelajaran matematika. Namun, hasil belajar matematika di Indonesia masih rendah, terutama karena pendekatan pembelajaran yang kurang efektif dan beragam. Penelitian ini menerapkan Model Problem Based Learning (PBL) dengan dukungan Lembar Kerja Peserta Didik (LKPD) berbasis Kontekstual pada Materi Barisan dan Deret untuk meningkatkan hasil belajar siswa. Melalui penelitian tindakan kelas di SMK N 07 Semarang, hasil menunjukkan peningkatan signifikan dalam pencapaian siswa. Dari hanya 22,2% siswa yang mencapai ketuntasan minimal sebelumnya, peningkatan pesat terjadi setelah menerapkan PBL dengan LKPD, mencapai 86,1% pada siklus kedua. Hasil ini menunjukkan potensi besar model pembelajaran tersebut dalam meningkatkan hasil belajar siswa. Integrasi PBL dengan LKPD berbasis kontekstual disarankan dalam kurikulum untuk meningkatkan hasil belajar secara menyeluruh dengan memperhatikan pelatihan guru dan pengembangan materi yang sesuai.

Abstract

HIV/AIDS is a global health issue that significantly impacts adolescents, a vulnerable group prone to risky behaviors such as unprotected sexual intercourse. The lack of knowledge is a key factor contributing to the increased risk of transmission. Therefore, effective health education interventions are essential to address this problem, with one promising approach being health promotion through audiovisual media. This study aims to assess the impact of audiovisual media on improving HIV/AIDS knowledge among 11th-grade students at SMA PGRI 2 Banjarmasin. The study used a quasi-experimental design with a one-group pretest–posttest approach. The entire population of 112 students was selected using a total sampling technique. The data collection tool was a questionnaire that was tested for validity and reliability. The data were analyzed using the Wilcoxon test, as the data were not normally distributed. Prior to the intervention, most students (85.7%) had low levels of knowledge about HIV/AIDS. Following the intervention, all students (100%) demonstrated a significant increase in knowledge, reaching a high level. The Wilcoxon test yielded a p-value of 0.001 (p<0.05), indicating a statistically significant effect. These findings suggest that audiovisual media is a highly effective method for improving adolescents’ knowledge about HIV/AIDS. It serves as both an engaging and preventive educational strategy, making it an important tool in promoting awareness and reducing the risk of HIV/AIDS transmission among youth.

Abstract

This study aims to improve student learning outcomes and engagement through the implementation of the Teaching at the Right Level (TaRL) approach combined with the Problem Based Learning (PBL) model. The TaRL approach focuses on teaching that is appropriate to each student's ability level, while PBL encourages students to actively solve relevant problems, so that it is expected to improve student engagement and learning outcomes. This study was conducted in the form of classroom action research (CAR) consisting of two cycles. Each cycle includes the planning, implementation, observation, and reflection stages. In the first cycle, the results of student learning completion reached 64%. After reflection and improvement in the first cycle, it was continued with the second cycle which showed an increase in student learning completion to 78%. There was a difference in increase of 14% between the first and second cycles. The results of this study indicate that the implementation of the TaRL approach combined with the PBL model can effectively improve student learning outcomes and engagement. The increase in learning completion from the first cycle to the second cycle illustrates that this approach and model are able to accommodate differences in student abilities and facilitate more effective and interesting learning. Thus, the TaRL approach and the PBL model can be used as effective learning strategies to improve the quality of education in the classroom.

Abstract

Penelitian ini bertujuan untuk mengungkap praktik etnomatematika yang terkandung dalam proses pembuatan pondasi rumah (ngijing) oleh tukang bangunan di Desa Gebang. Berangkat dari pandangan bahwa matematika merupakan praktik budaya yang hidup dalam aktivitas masyarakat, penelitian ini memfokuskan kajian pada penalaran matematis implisit yang digunakan dalam tahapan konstruksi pondasi rumah tradisional. Penelitian ini menggunakan pendekatan kualitatif dengan desain etnografi. Data dikumpulkan melalui observasi partisipan, wawancara mendalam tidak terstruktur, dan dokumentasi terhadap lima orang tukang bangunan yang berpengalaman. Analisis data dilakukan secara induktif melalui tahapan analisis domain, taksonomi, komponen, dan tema. Hasil penelitian menunjukkan bahwa proses ngijing terdiri atas beberapa tahapan utama, yaitu pembuatan sketsa, pengukuran dan penggalian tanah, pemasangan batu pondasi (kijing), serta pengecoran. Pada setiap tahapan tersebut ditemukan penerapan konsep matematika seperti skala, perbandingan, luas, jarak, bangun datar, bangun ruang, dan rasio material yang digunakan secara konsisten tanpa simbol matematika formal. Praktik tersebut mencerminkan penalaran matematis adaptif yang berkembang dari pengalaman kerja dan transmisi budaya. Penelitian ini menyimpulkan bahwa ngijing merupakan sistem etnomatematika yang bersifat prosedural dan kontekstual, bukan sekadar aktivitas teknis konstruksi. Temuan ini berkontribusi pada penguatan teori etnomatematika serta membuka peluang pemanfaatan praktik budaya lokal sebagai konteks pembelajaran matematika yang bermakna, khususnya pada materi pengukuran, perbandingan, dan geometri.

Abstract

Screen time yang tinggi dan aktivitas fisik yang rendah sering dikaitkan dengan masalah status gizi pada remaja, tercermin dari prevalensi obesitas usia 13–15 tahun di Kalimantan Selatan sebesar 3,91% dengan angka tertinggi di Kota Banjarmasin yaitu 8,38%, yang melampaui rata-rata provinsi dan mendekati target nasional RAN-PG dan SDGs (<15%). Perubahan gaya hidup akibat penggunaan gawai dan kurangnya aktivitas fisik berpotensi memengaruhi keseimbangan energi tubuh. Penelitian ini bertujuan untuk menganalisis hubungan screen time dan aktivitas fisik dengan status gizi pada siswa kelas VIII SMP Negeri 10 Banjarmasin. Penelitian ini merupakan penelitian kuantitatif dengan desain cross sectional. Populasi penelitian berjumlah 101 siswa dengan sampel sebanyak 81 siswa yang dipilih menggunakan teknik simple random sampling. Pengukuran screen time dilakukan menggunakan QueST, aktivitas fisik diukur dengan IPAQ-SF, sedangkan status gizi ditentukan berdasarkan Indeks Massa Tubuh (IMT). Analisis data menggunakan uji Spearman Rho. Hasil penelitian menunjukkan bahwa sebagian besar responden memiliki screen time kategori tinggi sebanyak 61 siswa (75,3%), hampir setengah responden memiliki aktivitas fisik rendah sebanyak 41 siswa (50,6%), dan sebagian besar responden memiliki status gizi kategori baik sebanyak 31 siswa (38,3%). Hasil uji statistik menunjukkan tidak terdapat hubungan antara screen time dengan status gizi (p value=0,622; r=-0,056) maupun antara aktivitas fisik dengan status gizi (p value=0,427; r=0,090). Pendekatan kesehatan yang komprehensif perlu diperkuat untuk mendukung pemeliharaan status gizi remaja. Penelitian selanjutnya disarankan untuk menggunakan desain longitudinal serta mempertimbangkan faktor lain, seperti pola makan dan penyakit guna memperoleh gambaran hubungan yang lebih komprehensif.

Abstract

Background: Mathematics education in vocational schools faces challenges in fostering students’ creative thinking, particularly in understanding abstract concepts and generating alternative solutions. Classroom practices often emphasize procedural replication, while teachers encounter difficulties in addressing diverse learning needs, highlighting the need for innovative, contextual, and culturally responsive approaches. Aims: This study aims to strengthen vocational students’ creative thinking in mathematics by designing an integrated instructional model that combines pedagogy, technology, and cultural elements. Methods: A qualitative design thinking approach was applied through the stages of Empathize, Define, Ideate, Prototype, and Test/Evaluate. Data were collected using questionnaires, interviews, and classroom observations to identify student and teacher needs. The proposed model was further examined through a meta-analysis using effect size calculations to synthesize findings from relevant empirical studies. Results: The findings indicate that students need more flexible, innovative, and culturally meaningful learning experiences. An instructional prototype, Gema-Batik, was developed by integrating Project-Based Learning, ethnomathematics, GeoGebra, and jBatik within a design thinking framework. The model emphasizes problem orientation, exploration, digital modeling, motif creation, and presentation, targeting creative thinking indicators such as fluency, flexibility, originality, and elaboration. Meta-analytic results show a high pooled effect size, indicating strong potential to enhance creative thinking and related competencies. Conclusion: The Gema-Batik model offers a novel, culturally grounded, and technology-integrated approach that contributes both theoretically and practically to vocational mathematics education, particularly in fostering creative thinking aligned with the demands of creative industries.
