Abstract

Penelitian ini bertujuan untuk mengembangkan e-modul STEM berbasis literasi sains pada sub materi pencemaran lingkungan topik pencemaran air, serta alat filtrasi air sederhana sebagai bagian dari implementasi pendekatan STEM berbasis literasi sains yang valid dan praktis sehingga layak digunakan dalam pembelajaran. Penelitian ini menggunakan metode Research and Development (R&D) dengan model pengembangan ADDIE yang terdiri dari lima tahapan yaitu: (1) Analisis, (2) Desain, (3) Pengembangan, (4) Implementasi, dan (5) Evaluasi. Uji coba e-modul dan alat filtrasi air sederhana dilakukan di SMP Itas Rios Sorong dengan melibatkan 14 peserta didik kelas VII sebagai subjek penelitian. Berdasarkan hasil analisis data, diperoleh penilaian dari ahli materi 1 sebesar 88,91%, ahli materi 2 sebesar 100%, ahli media 1 sebesar 99.17%, dan ahli media 2 sebesar 99.31%. Hasil penilaian dari ahli materi dan ahli media memenuhi kategori “sangat layak”. Selain itu, hasil angket respon peserta didik menunjukkan bahwa seluruh siswa memberikan tanggapan positif terhadap e-modul dan alat filtrasi aie sederhana dengan hasil presentase sebesar 96,67%. Dengan demikian, hasil penelitian ini menunjukkan bahwa E-modul STEM berbasis literasi sains pada sub materi pencemaran lingkungan topik pencemaran air beserta alat filtrasi air sederhana dinyatakan layak digunakan sebagai bahan ajar dalam pembelajaran untuk siswa kelas VII SMP Itas Rios Sorong.

Abstract

Scientific literacy is an essential competence that elementary school students must possess to face the challenges of the 21st century. However, Indonesian students’ scientific literacy remains relatively low. One effort to improve scientific literacy is through the implementation of the Read, Answer, Discuss, Explain, and Create (RADEC) learning model. This study aimed to determine the effect of the RADEC learning model on fifth-grade students’ scientific literacy in ecosystem materials. This study employed a quantitative approach using a pre-experimental one-group pretest-posttest design. The subjects were 30 fifth-grade elementary school students. Data were collected using a scientific literacy test administered before and after the implementation of the RADEC learning model. Data analysis techniques included normality tests, reliability tests, and paired sample t-tests using SPSS. The results showed an increase in students’ scientific literacy scores after the implementation of the RADEC learning model. The paired sample t-test results indicated a significance value of less than 0.05, indicating that the RADEC learning model had a significant effect on students’ scientific literacy in ecosystem learning.

Abstract

Mathematics learning difficulties significantly impede elementary students' academic development, yet limited research examines practical intervention strategies for resource-constrained rural contexts. This qualitative descriptive study investigated factors contributing to mathematics learning difficulties among third-grade students at Muhammadiyah Rawa Sugih Elementary School, Indonesia. Data were collected through semi-structured interviews with one classroom teacher and one principal, supplemented by systematic classroom observations over one month (eight sessions). Analysis followed Miles and Huberman's interactive model, with source triangulation ensuring validity. Students exhibited three primary difficulty categories: conceptual understanding of multiplication/division, procedural computational fluency, and word problem comprehension. Internal factors—low motivation, minimal interest, and negative attitudes—dominated as primary contributors, reinforced by external factors including limited parental support, disruptive peer influences, and inadequate instructional resources. Teacher intervention strategies combining individual guidance, systematic material repetition, mobile phone-based audio-visual media, and WhatsApp-mediated parent communication demonstrated modest effectiveness in enhancing student engagement and homework completion rates (40% to 75%). Findings support ecological-transactional models wherein learning difficulties emerge from dynamic interactions between individual characteristics and environmental conditions rather than solely individual deficits. The integration of accessible digital communication platforms represents a scalable innovation for strengthening home-school partnerships in resource-limited settings, extending theoretical understanding of technology-mediated parental involvement in elementary mathematics education.
