This research follows the research and development (RnD) approach using the Thiagarajan 4D development model. Various methods were employed to collect data, including interviews, observation, questionnaires, and documentation. The e-module was developed in the form of digital Flipbooks, which present students with a step-by-step learning process based on the Science Writing Heuristic. The quality of the e-module was evaluated by expert validators and student feedback. The final product is an e-module based on the Science Writing Heuristic (SWH) in HTML five format. The e-module received high scores from material and media experts, with a score of 0.93 and 0.82 respectively. Student responses were also positive, indicating its potential as a valuable learning resource. Further testing is required to determine its effectiveness in larger classroom settings. 2023-07-06T10:58:47Z 2023-07-06T10:58:47Z 2023-06-05 journal article Mohzana, Agus Rofi’i, Antonia Junianty Laratmase, Susatyo Adhi Pramono, Enny Diah Astuti (2023).
