Abstrak

This research aimed to investigate the effect of the Cooperative Learning model assisted by Wordwall on students’ writing ability in descriptive text. The study was conducted at SMA Negeri 2 Tanjungbalai in the 2025/2026 academic year using a quantitative quasi-experimental design with two groups: an experimental class and a control class. The sample consisted of 46 students, with 22 students in the experimental class and 24 students in the control class. The data were collected through pre-test and post-test writing assessments and analyzed using the t-test formula. The results showed that the mean score of the control class increased from 54.5 in the pre-test to 72.5 in the post-test, while the experimental class showed a greater improvement after being taught using the Cooperative Learning model assisted by Wordwall. The hypothesis testing revealed that the t-count value was higher than the t-table value at the significance level of 0.05 with the degree of freedom (df) 44, indicating a statistically significant difference between the two groups. Based on these findings, the null hypothesis (Ho) was rejected and the alternative hypothesis (Ha) was accepted. It can be concluded that the Cooperative Learning model assisted by Wordwall has a significant positive effect on students’ writing ability in descriptive text. Therefore, this method is recommended as an effective teaching strategy to improve students’ writing achievement.
