Abstract

Engaging and pedagogically relevant learning media are essential for improving students’ conceptual understanding in chemistry, particularly on abstract topics such as acid–base solutions. This study aimed to develop a contextual animated video using the Powtoon web application to enhance student engagement and comprehension through real-life connections. The development followed the 4D model (Define, Design, Develop, Disseminate) and was conducted at a public senior high school in Yogyakarta. Participants included chemistry education lecturers (as media and content experts), high school chemistry teachers (for practicality evaluation), and 11th-grade science students (for readability testing). The animation incorporated core elements of contextual learning, such as inquiry, questioning, learning community, modelling, and reflection, to foster deeper understanding. Validation results indicated excellent quality, with ideal scores of 95% from media experts and 90% from content experts. Teachers rated the practicality at 92%, while students rated the video’s readability at 95%. All evaluations were categorized as “very good.” Quantitative data were analyzed descriptively using ideal percentage scores. These findings demonstrate that the developed animation is both pedagogically sound and technically effective in supporting student learning. This research contributes to the field of chemistry education by offering an accessible digital resource that supports contextualized instruction and increases student motivation and understanding of acid–base concepts.

Abstract

The research for the development of the interactive multimedia IMPAC carries important implications for chemistry education, particularly in the topic of acid-base solutions. The contextual approach applied makes the material more relevant to students’ daily lives, thereby enhancing their motivation and engagement in learning. Research method 4D Development. Validation by media and content experts, as well as practicality tests by teachers and readability tests by students, respectively, resulted in ideal scores of 95%, 87%, 92%, and 94%. All scores were categorized as “Very Good,” reinforcing IMPAC's feasibility for broader implementation. Therefore, IMPAC has the potential to serve as an innovative and effective learning medium that not only strengthens conceptual understanding but also fosters a more engaging, interactive, and meaningful chemistry learning experience. The implication for research is to provide recommendations for teaching materials on the acid-base solutions topic.
PENGARUH MODEL PEMBELAJARAN RADEC TERINTEGRASI ETNOKIMIA TERHADAP KEMAMPUAN BERPIKIR KRITIS DAN KETERAMPILAN KOMUNIKASI PESERTA DIDIK PADA MATERI GREEN CHEMISTRY Antika, Vivi Dwi; Arianingrum, Retno; Mutiarasani, Dwi Rizki

Abstract

Mengkaji bagaimana keterampilan berpikir kritis dan komunikasi siswa dalam Green Chemistry dipengaruhi oleh paradigma pembelajaran RADEC (Read, Answer, Discuss, Explain, Create) yang mencakup etnokimia ialah tujuan utama dari penelitian ini. Penelitian ini mempergunakan desain quasi-experimental dengan dua kelompok: satu kelompok menggunakan model Discovery Learning sebagai kontrol, sementara kelompok lainnya menggunakan model RADEC dengan ethnochemistry sebagai komponen eksperimen. Sampel penelitian terdiri dari empat kelas X SMA Negeri 5 Cirebon yang ditentukan melalui random sampling setelah uji normalitas dan homogenitas. Instrumen penelitian meliputi tes two-tier multiple choice untuk mengukur kemampuan berpikir kritis serta angket dan lembar observasi untuk menilai keterampilan komunikasi. Analisis data mempergunakan N-gain, MANOVA, dan effect size. Hasil penelitian memperlihatkan model RADEC lebih efektif dibandingkan Discovery Learning, dengan peningkatan N-gain kemampuan berpikir kritis sebesar 0,51 (kategori sedang) dan keterampilan komunikasi senilai 0,49 (kategori sedang), lebih tinggi dibandingkan kelas kontrol. Uji MANOVA mengonfirmasi adanya perbedaan signifikan (p 0,05), dengan kontribusi efektif senilai 53,1% secara simultan, 13,0% pada berpikir kritis (efek sedang), dan 51,5% pada komunikasi (efek besar). Simpulannya ialah bahwa model RADEC terintegrasi etnokimia efektif meningkatkan kemampuan berpikir kritis dan keterampilan komunikasi, sekaligus menguatkan relevansi pembelajaran kimia dengan konteks budaya lokal.
