The current emphasis is on enhancing fourth graders' IPAS learning through the use of engaging learning materials, as there has been little innovation in this area. Using cutting-edge interactive media, this study intends to develop an E-module using 1stflip Flipbook in order to raise students' engagement, performance, and the overall quality of their education. The R&D approach, namely the ADDIE model, is utilized for the research. Experts in media, materials, and languages validated the research instruments. Validators filled out questionnaires, and students took pretests and post-tests; data was gathered through interviews and observations. The data was analyzed using quantitative and descriptive methods. The results of the validation showed that the E-module was valid at 78.3%, with an N-Gain value of 63.16% for the experimental class and 29.39% for the control class. The results of the hypothesis test demonstrated that the group of students who used the E-module significantly outperformed the control group in terms of their metacognitive skill improvement. There is significant value in enhancing the quality of learning through the usage of E-Modules with 1stflip Flipbook to enhance IPAS learning in primary schools.
