Abstract

This study aims to analyze the effectiveness of the Project-Based Flex Blended Learning (PjBFBL) model in improving students' critical thinking skills on Ohm's Law material in science courses. The quasi-experimental method uses a Nonequivalent Control Group Design with 41 fourth semester students divided into experimental (PjBFBL) and control (conventional) groups. Instruments include critical thinking tests based on seven indicators (interpretation, analysis, evaluation, inference, explanation, self-regulation, essential questions), analyzed using N-Gain, T-test, and effect size. Results showed the experimental group achieved a moderate N-Gain improvement (0.63) with the highest categories in inference (0.78; high) and explanation (0.73; high), while the control group only had a low N-Gain (0.28). The independent T-test confirmed the significant difference (t (25,092) = 7.230; p<0.05) with an average difference of 35.78% and a large effect size (Cohen's d=2.299). The research conclusion indicates that the PjBFBL model effectively improves critical thinking skills, particularly in multidimensional reasoning and information synthesis, through the integration of authentic projects, hybrid flexibility, and structured collaboration. The findings recommend the adoption of this model in science learning to bridge the 21st century competency gap, noting the need to strengthen the interpretation aspect through more contextualized instruments

Abstract

This study aims to develop Quizizz-based E-LKPD containing Higher Order Thinking Skills (HOTS) on the material of Plants as Sources of Life on Earth for fourth-grade elementary school students. This study uses the Research and Development (R&D) method with the ADDIE development model which includes the stages of analysis, design, development, implementation, and evaluation. The instruments used are validation sheets from material experts, media experts, and student response questionnaires. The results of the study show that the developed E-LKPD obtained the category of Feasibility of Quizizz-Based Student Worksheets on the Material of Plants as Sources of Life on Earth for Grade IV at SD Negeri 21 Limboto in the category of "Very Feasible". This was obtained from the results of the media expert validation which obtained a percentage of 90% or categorized as "Very Feasible", the results of the material expert validation obtained a percentage of 95% or categorized as "Very Feasible", the HOTS item expert validation result got 87,5% and the results of the teacher response questionnaire obtained an average percentage of 90% or categorized as "Very Feasible" and the results of the student response questionnaire obtained an average percentage of 95,6% or categorized as "Very Feasible".
