Pengembangan Media Pembelajaran Ecoviar dengan Model Inquiry learning untuk Meningkatkan Computational Thinking  dan Literasi Sains Peserta didik Kelas V Sekolah Dasar

Development of ‘Ecoviar’ Learning Media Using the Inquiry Learning Model to Enhance Computational Thinking and Scientific Literacy of Fifth-Grade Elementary School Students

Pembelajaran IPAS materi Harmoni dalam Ekosistem masih menghadapi kendala dalam memfasilitasi peserta didik memahami konsep yang abstrak serta mengembangkan computational thinking dan literasi sains secara optimal. Media yang tersedia masih mengandalkan buku dan penjelasan guru, sehingga belum mampu memvisualisasikan hubungan antar komponen ekosistem secara komprehensif. Oleh karena itu, penelitian ini bertujuan untuk mengembangkan serta menguji kelayakan dan keefektifan media pembelajaran Ecoviar (Ecosystem via Augmented Reality) untuk mendukung pembelajaran kontekstual dan bermakna. Pengembangan media dilakukan menggunakan The Holistic 4D Model dari Reigeluth yang terdiri atas tahap define, design, develop, dan deploy. Subjek penelitian terdiri dari peserta didik kelas V SD, masing masing 24 siswa untuk kelas eksperimen dan kelas kontrol. Teknik pengumpulan data menggunakan angket validasi ahli (media, desain pembelajaran dan evaluasi pembelajaran), angket respons peserta didik, serta tes extended response terpimpin. Analisis data dilakukan dengan teknik statistik deskriptif untuk kelayakan dan uji beda menggunakan Independent Sample t-test untuk mengukur keefektifan media terhadap computational thinking dan literasi sains. Hasil validasi menunjukkan bahwa media Ecoviar masuk kategori sangat valid. Validasi media AR memperoleh skor 98,2%, bahan penyerta 100%, modul ajar 96.8%, dan LKPD 100%. Hasil uji one-on-one (95,8%) dan small group test (91,4%) menunjukkan media mudah digunakan, menarik, serta membantu peserta didik memahami konsep ekosistem. Pada uji keefektifan, terdapat perbedaan signifikan antara kelas eksperimen dan kelas kontrol baik pada kemampuan Computational thinking (Sig. 0.002) maupun literasi sains (Sig. 0.000) yang mana nilainya < 0,05. Secara keseluruhan, disimpulkan bahwa media Ecoviar sangat layak dan efektif untuk digunakan dalam pembelajaran IPAS kelas V.

Learning IPAS on the topic Harmony in Ecosystems still faces challenges in facilitating students’ understanding of abstract concepts and in optimally developing computational thinking and scientific literacy. The available learning media continue to rely on textbooks and teacher explanations, which are insufficient to comprehensively visualize the relationships among ecosystem components. Therefore, this study aims to develop and examine the feasibility and effectiveness of Ecoviar (Ecosystem via Augmented Reality) to support contextual and meaningful learning. The media development employed Reigeluth’s Holistic 4D Model, which consists of the define, design, develop, and deploy stages. The research subjects were fifth-grade elementary school students, with 24 students in the experimental group and 24 students in the control group. Data collection techniques included expert validation questionnaires (media, instructional design, and learning evaluation experts), student response questionnaires, and guided extended-response tests. Data analysis was conducted using descriptive statistical techniques to determine media feasibility and an Independent Samples t-test to measure the effectiveness of the media on computational thinking and scientific literacy. The validation results indicated that Ecoviar was categorized as highly valid. The augmented reality media obtained a validation score of 98.2%, supporting materials 100%, instructional modules 96.8%, and student worksheets 100%. The results of the one-on-one test (95.8%) and small group test (91.4%) showed that the media was easy to use, engaging, and effective in supporting students’ understanding of ecosystem concepts. Effectiveness testing revealed significant differences between the experimental and control groups in both computational thinking (Sig. = 0.002) and scientific literacy (Sig. = 0.000), with significance values less than 0.05. Overall, Ecoviar is highly feasible and effective for use in fifth-grade IPAS learning.
