PENGEMBANGAN E-FLIPBOOK MATERI PERUBAHAN LINGKUNGAN UNTUK MELATIHKAN LITERASI DIGITALAbstractDigital literacy is one of the abilities that students need to master in the 21st century. Therefore, this study aims to produce an e-flipbook of environmental change topics to train digital literacy, which is valid, practical, and effective. As a developmental study, it refers to a 4-D model, without a dissemination phase. The material validity was measured based on the validation by material, educational, and information-technology experts. Furthermore, the e-flipbook practicality was measured based on the practitioners and student responses. Also, the effectiveness was measured according to students' digital literacy based on normalized gain score, and the data were descriptive-quantitatively analyzed. The results showed the developed e-flipbook was declared valid based on the eligibility criteria for design, content, and language. Furthermore, it was stated to be practical according to the responses of practitioners and students with the acquisition of very practical and good categories. The e-flipbook was also declared effective with the acquisition of an average score of increasing digital student literacy by 0.7 in the high category. Therefore, it can be concluded that the e-flipbook on environmental change topic is valid, practical, and effective in learning digital literacy.
