Abstract


This study aims to develop a valid, practical, and effective flipbook-based Science e-book on Theme 1 Light and Its Properties in the form of a flipbook based on the 5E Learning Cycle to improve critical thinking skills for fifth-grade elementary school students. The study uses the Research and Development (R&D) method with the ADDIE model which includes Analysis, Design, Development, Implementation, and Evaluation. The research subjects consisted of 30 fifth-grade students of SD Kristen Kalam Kudus 2 Pematangsiantar. The research instruments were expert validation sheets, student and teacher response questionnaires, and critical thinking ability tests through pretest and posttest. The validation results showed that the e-book was very valid, with a percentage of 88% from material experts, 86% from media experts, 92% from language experts, and 84% from test instrument experts. The practicality of the e-book reached 88% based on student responses and 92% from teacher responses, with an average of 90% categorized as very practical. The effectiveness is shown through an increase in the average value from 59.83 in the pretest to 86.17 in the posttest, with an N-Gain of 0.655 in the moderate category. The One Sample t-Test obtained a Sig. (2-tailed) value = 0.000 < 0.05, so that the posttest average has exceeded the KKTP of 75. Thus, the developed e-book is declared very valid, very practical, and effective in improving students' critical thinking skills.
