This difficulty is triggered by learning activities that lack variety and limited media to support independent learning. This study focuses on the effectiveness of the Discovery Learning model based on interactive websites in improving the writing skills of third-grade students. Using a one-group quasi-experimental pretest–posttest design, the study involved 25 students. Data were obtained through writing tests that assessed content accuracy, structure, language, spelling, and creativity. The results showed a significant increase from an average score of 66.72 to 86.4. The N-Gain score of 0.58 was in the moderate category, while the t-test produced a t-count of 19.093 > t-table 2.063. These findings confirm that interactive website-assisted Discovery Learning is effective in improving students' writing skills. Keywords— discovery learning, simple texts, interactive websites]]>
