This study was conducted to examine the effectiveness of the 3I’s method (Instruct, Integrate, and Involve) in enhancing students’ ability to write recount texts at SMK Negeri 2 Parepare. A quasi-experimental research design was employed, involving both experimental and control groups that completed pre-tests and post-tests. The participants were eleventh-grade students, and the sample was selected through cluster random sampling. Class XI DKV C served as the experimental group, while Class XI TITL B functioned as the control group, with 21 students in each class. Data were collected using a recount writing test evaluated according to five writing components: content, organization, vocabulary, language use, and mechanics, based on Heaton’s scoring rubric. The collected data were analyzed using descriptive statistics and an independent samples t-test. The findings revealed that the experimental group achieved a higher mean post-test score (86.05) than the control group (81.52). In addition, the statistical analysis produced a significance value of 0.029, which was lower than the 0.05 threshold, indicating a significant difference between the groups. These results suggest that the 3I’s method effectively improves students’ recount writing performance, particularly in generating ideas, applying grammar accurately, and producing well-organized texts. Therefore, the 3I’s method can be recommended as an effective instructional approach for teaching writing in vocational high school settings.
