Heyzine Flipbook Digital Teaching Materials for Science Critical Thinking Skills

General Background: Science education in elementary schools frequently relies on conventional teaching materials, which often center on the teacher rather than the student. Specific Background: This traditional approach frequently fails to optimally foster critical thinking, a vital skill for 21st-century learners. Knowledge Gap: Existing materials lack the interactive elements necessary to challenge students to analyze, evaluate, and infer information effectively. Aims: This study aimed to develop, validate, and test the practicality and efficacy of digital teaching materials assisted by Heyzine Flipbook to improve students' critical thinking in grade V science learning. Results: The research, utilizing the ADDIE model, produced valid digital materials validated by experts with a Gregory coefficient of 1.0. Practicality assessments yielded scores of 92.31% from teachers and 87.5% from students, indicating high usability. Independent sample t-test results (significance 0.001 < 0.05) confirmed that students using these materials significantly outperformed the control group, with average post-test scores of 75.78% versus 57.66%. Novelty: The integration of multimedia, digital worksheets, and interactive quizzes within a Heyzine Flipbook platform provides a structured, innovative environment that specifically targets high-level thinking indicators. Implications: These findings demonstrate that Heyzine Flipbook-assisted materials serve as an effective, student-centered alternative to reduce teacher-dominated instruction and enhance science learning quality in elementary education. Highlights Heyzine Flipbook integration creates a comprehensive, interactive digital learning environment featuring integrated videos and digital worksheets. The developed digital materials achieved high validity and practicality scores, proving highly usable for both educators and students. Statistically significant improvements in critical thinking scores were recorded in experimental classes compared to traditional learning methods Keywords: Digital Teaching Materials; Heyzine Flipbook; Science Learning; Critical Thinking Skills; Elementary School
