<![CDATA[The Think Talk Write (TTW) learning model is considered effective for teaching descriptive text writing, as it helps students express their ideas and opinions more clearly. This study aims to determine the effect of the TTW model on the ability to write descriptive texts among fifth-grade students at SD Negeri 155 Sayur Matinggi. The research employs a quantitative approach with a pre-experimental design, specifically a one-group pretest-posttest design. The population consisted of all 29 fifth-grade students at the school. Data were collected using written tests focused on descriptive paragraph writing, administered before and after the implementation of the TTW model. The pretest results showed an average score of 42.75, categorized as very poor, indicating that students initially struggled with writing descriptive texts. After the intervention using the TTW model, the posttest results showed a significant improvement, with an average score of 78.27, categorized as sufficient. Hypothesis testing was conducted using SPSS version 23, which yielded a t-count of 11.892, higher than the t-table value of 1.701 at a significance level of 0.05. Since the t-count exceeded the t-table value (11.892 > 1.701), the hypothesis was accepted, confirming a significant effect of the TTW model on students’ descriptive writing ability. These findings suggest that the Think Talk Write learning model effectively enhances descriptive text writing skills and can be a beneficial instructional strategy for elementary school students.]]>
