Abstract

This study aims to develop environment-based digital flipbook teaching materials to enhance elementary school students' learning independence, particularly on the topic of food chains. The research employed a Research and Development (R&D) method using the ADDIE model. The instruments used in this research included observation, interviews, questionnaires, and learning outcome tests. Data analysis techniques comprised feasibility testing, effectiveness testing, user response testing (students and teachers), and assessment of students' learning independence level. The results show that the digital flipbook was highly feasible, with media expert validation scoring 90.43% and material expert validation scoring 84.37%. The effectiveness test revealed a significant improvement in learning outcomes, with the average pretest score increasing from 55.52 to 90.34 in the posttest, and an N-Gain score of 78.28% (high category). Moreover, student and teacher responses to the flipbook were highly positive, with percentages of 95.47% and 98.33%, respectively. Additionally, students' learning independence significantly increased, reaching 86.89%, which falls into the very high category. These findings suggest that the environment-based digital flipbook is effective in strengthening conceptual understanding of food chains while fostering learning independence through an interactive, contextual, and enjoyable approach.

Abstract

One of the problems faced in the world of education is the problem of learning that needs to involve students in the learning process. Teachers still need to implement the use of learning models fully, so the learning process is only teacher-centered, and learning does not involve active students. This research was conducted to determine the effect of applying the discovery learning model on students' learning outcomes on the protists concept using the quasi-experimental method. The results showed that the students' learning outcomes on the protists concept in the experimental class after applying the discovery learning model on the protists concept (= 43.2) is better than the control class (= 40.6). In can be concluded that the there is an effect of applying the discovery learning model on students' achievement on the protists concept.
