<![CDATA[This study was motivated by the low science learning outcomes of fourth-grade students and their suboptimal engagement in the learning process. Teaching that remains teacher-centered causes students to tend to be passive, resulting in incomplete mastery of the material. Therefore, a learning model is needed that can actively engage students in the learning process. This study aims to determine the effect of the Think Talk Write learning model based on Tri Kaya Parisudha on the IPAS learning outcomes of fourth-grade students. This study is a quantitative study using a quasi-experimental design with a non-equivalent control group design. The population in this study consists of all fourth-grade elementary school students. The research sample comprises an experimental class and a control class, selected using sampling techniques. Data collection was conducted using a test method consisting of multiple-choice questions. The obtained data were analyzed using descriptive analysis and inferential statistics. The hypothesis was tested using an independent samples t-test with the assistance of SPSS software. The results of the study indicate that there is a difference in learning outcomes between the experimental class and the control class. This is evidenced by the results of the hypothesis test, which show a significance level (Sig. 2-tailed) of 0.000 < 0.05. Furthermore, the average learning outcomes of students in the experimental class were higher than those in the control class. Thus, it can be concluded that the Think Talk Write learning model based on Tri Kaya Parisudha has a significant effect on the IPAS learning outcomes of fourth-grade students. ]]>
