Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemahaman teks akademik terhadap proses pembelajaran mahasiswa jurusan kimia, fakultas matematika dan ilmu pengetahuan alam, Universitas Negeri Medan. Penelitian ini melibatkan 20 responden dari jurusan dan universitas yang sama. Metode penelitian menggunakan kuisioner Google Forms sebagai alat pengumpulan data untuk hasil analisis penelitian. Hasil penelitian menunjukkan bahwa 90% mahasiswa setuju bahwa ada pengaruh yang signifikan pada hasil pemahaman teks akademik terhahadap proses pembelajaran mahasiswa. Dengan demikian, sangat penting bagi mahasiswa khususnya jurusan kimia memiliki pemahaman yang tinggi terhadap suatu teks akademik untuk menunjang proses perkuliahannya di suatu sekolah tinggi.

Abstract

This study aims to develop a green chemistry-oriented virtual laboratory integrated with Project-Based Learning (PjBL) and evaluate its effectiveness in improving student learning outcomes in redox titration. The study used a Research and Development (R&D) approach with the ADDIE model and a quasi-experimental two-group pretest–posttest design. The sample consisted of 72 Chemistry Education students at Universitas Negeri Medan divided into experimental and control classes. Expert validation categorized the media as highly feasible with an average BSNP score of 3.42 in content, language, presentation, and graphics. The experimental class achieved a higher posttest score (79.55 ± 5.75) than the control class (64.55 ± 13.94). The Wilcoxon Signed-Rank Test showed a significant improvement in the experimental class (Z = -4.247, p = 0.000). The experimental class also obtained a higher N-Gain score (0.61) than the control class (0.49), with a significant difference in effectiveness (p = 0.003).
