THE EFFECT OF COOPERATIVE LEARNING MODEL ON STUDENTS’ ABILITY IN WRITING OF PROCEDURE TEXT AT GRADE XI OF SMA NEGERI 1 AEK SONGSONGAN IN 2025/2026 ACADEMIC YEAR

Abstrak

The aim of this study was to determine how the Cooperative Learning model affected the eleventh-grade students at SMA Negeri 1 Aek Songsongan's capacity to write procedure texts throughout the 2025/2026 school year. Two groups an experimental group and a control group were involved in the study's quantitative methodology. The total number of participants was 72 students, divided equally into both groups. The data were gathered through writing tests in the form of a pre-test and a post-test. The experimental group was taught using the Cooperative Learning model, while the control group was taught through conventional teaching methods. The findings showed that the students in the experimental group experienced a significant improvement, as their mean score increased from 67.7 in the pre-test to 83.3 in the post-test. On the other hand, the control group also showed improvement, but at a lower level, with their mean score rising from 55 to 67.3. Moreover, the t-test results revealed that the obtained t-value (7.01) exceeded the critical t-table value (1.667) at the 0.05 significance level. This finding shows that a statistically significant difference existed between the two groups. Consequently, the alternative hypothesis (Ha) was accepted, while the null hypothesis (Ho) was rejected. In summary, the Cooperative Learning model was demonstrated to have a meaningful effect on students’ ability in writing procedural texts.
