Pengembangan Model Pembelajaran Problem Based Learning Terintegrasi Literasi Digital untuk Meningkatkan Kemampuan Berpikir Kritis dan Komunikasi Siswa

Abstract

This development research was motivated by the suboptimal achievement of 21st-century skills, particularly critical thinking and communication, in science learning that remains teacher-centered and relies on conventional teaching materials. The study aimed to design a Problem Based Learning (PBL) model integrated with digital literacy and to describe its validity, practicality, and effectiveness. The ADDIE model (Analysis, Design, Development, Implementation, Evaluation) was used. Five expert validators assessed the model, while practicality and effectiveness were tested on 28 ninth-grade students of MTs Mazra'atul Ulum Paciran, Lamongan, on the topic of heredity. The product is a modified PBL syntax that employs WhatsApp, Google Docs, web searching, and Canva, supported by a teaching module, student worksheets, and assessment instruments. Data were analyzed using descriptive quantitative statistics. The model was rated very valid (93.6%) and very practical (90.18%). In the effectiveness test, the mean critical thinking score was 88.17 and the mean communication score was 93.21, with 89.29% and 85.71% of students in the very good category, respectively. Teacher activity (90.01%), student activity (93.75%), learning management (90.63%), and student responses (89.98%) were also in the very good category. The model is therefore feasible as an alternative for training critical thinking and communication in science learning. Because the trial involved one class without a control group, further quasi-experimental testing is needed to confirm its effect on skill improvement.
