Abstract

Tujuan dari penelitian ini untuk mengetahui pengaruh modul koloid berorientasi chemoentrepreneurship terhadap hasil belajar siswa kelas XI SMA Negeri 2 Medan. Jenis penelitian ini menggunakan kelompok kontrol non-ekuivalen dan desain penelitian kuasi eksperimen. Dua kelas XI IPA SMA Negeri 2 Medan dijadikan sebagai subjek penelitian dan sampel diambil secara acak. Uji N-gain dan uji kesamaan dua rata-rata (uji-t) digunakan untuk menganalisis data. Perolehan rata-rata pretest kelas eksperimen adalah 39,72, sedangkan kelompok kontrol adalah 39,03. Perolehan rata-rata posttest untuk kelas eksperimen adalah 83,19, sedangkan untuk kelas kontrol adalah 77,64. Hasil uji-t diperoleh thitung>ttabel (3,74>2,34), yang menunjukkan bahwa Ho ditolak dan Ha diterima. Hasil uji n-gain untuk kelas eksperimen sebesar 71%, sedangkan untuk kelas kontrol sebesar 59%. Hal ini menunjukan bahwa modul koloid berbasis chemoentrepreneurship efektif digunakan untuk meningkatkan pemahaman dan ketertarikan dalam proses pembelajaran.

Abstract

The low conceptual understanding of physics education students, often caused by conventional teaching materials and a lack of self-study guidance, indicates the need for innovation. This research aims to develop a web-based student worksheet (web-LKPD) integrated with the STEM approach and supplemented with scaffolding. The developed web-LKPD is designed to improve the conceptual understanding of physics education students. The method used is research development with the ADDIE development model (analysis, design, development, implementation, and evaluation). The subjects of this study were physics education students at the Faculty of Teacher Training and Education, Jambi University. The instruments included questionnaires, interviews, conceptual understanding tests (pretest and posttest), and student response questionnaires. The data were analyzed using quantitative and qualitative descriptive techniques. The results showed that the developed web-LKPD was highly suitable for use, evidenced by the average feasibility percentage from media experts of 93% and material experts of 83.2% (very good). The product also received a positive response from students (89.7%, very good). Paired t-test analysis concluded that there was a significant difference between the pretest and posttest results, indicating that the web-LKPD has a significant impact on improving students' conceptual understanding
