Abstract

This research develops cognitive diagnostic assessment instruments and cognitively differentiated worksheets designed to enhance students' scientific literacy in science learning. Using a Research and Development (R&D) approach based on the Plomp model, the study involved 28 students, each from Class IV A and IV B at MIN 1 North Lampung. Data was collected through documentation, questionnaires, interviews, and observation, and analyzed using t-tests, practicality tests, and product validation. Expert validation showed the instruments and worksheets were highly valid, with average scores of 92% for cognitive diagnostic assessment questions, 94% for post-test questions, and 94% for material, linguistic, and media validation. The practicality test showed educators' responses at 84% and students' at 87%, both rated as very practical. A t-test revealed a significant difference (p = 0.001, p < 0.05) between the experimental and control classes in post-test scores. The results indicate that the developed cognitive diagnostic assessment instruments and differentiated worksheets are valid, practical, and effective in enhancing students' scientific literacy.

Abstract

Critical thinking skill is a skill that students need to have in the 21st century. When students have critical thinking skills, they are expected to be able to seriously understand, analyze, and process the information before making a decision. The research objective is to improve students' critical thinking skills through PBL-based worksheets on the subject of the human digestive system. This LKPD product was developed using the ADDIE model, which was tested at MIN 2 West Lampung. As many as 15 students were in the control class and 25 students were in the experimental class. The research results indicate that the validated LKPD based on the validity test analysis using Aiken reveals a score of 0.8210 in the valid category. The analysis of the practicality test indicates 85% for educators and 88% for students, both are in the very practical category. The product effectiveness analysis reveals an average pre-test score of 58.4 and an average post-test score of 83.2. The development of worksheets based on the PBL model has a significant influence on students' critical thinking skills.
