THE EFFECT OF DISCOVERY LEARNING MODEL ON STUDENTS’ ABILITY IN WRITING PROCEDURE TEXT AT GRADE X OF SMA SWASTA MERANTI IN 2025/2026 ACADEMIC YEAR

Abstrak

This study aimed to determine the significant effect of the Discovery Learning model on students’ ability in writing procedure texts at Grade X of SMA Swasta Meranti in the 2025/2026 academic year. Writing is considered one of the most complex language skills because it requires the integration of multiple components such as content, organization, vocabulary, grammar, and mechanics. Therefore, an effective instructional model is needed to support students in improving their writing ability. This research applied an experimental quantitative method using a pre-test and post-test control group design. The population consisted of 64 students, which were divided into two groups: an experimental group and a control group. The experimental group was taught using the Discovery Learning model, while the control group was taught using a conventional method. The data were collected through writing tests and analyzed using the t-test formula. The findings showed that the experimental group achieved a higher improvement compared to the control group. The result of the t-test calculation indicated that the obtained value was higher than the t-table value at the significance level of 0.05. This means that the alternative hypothesis was accepted. It can be concluded that the Discovery Learning model has a significant effect on students’ ability in writing procedure texts. The model enhances students’ engagement, critical thinking, and ability to organize ideas effectively.
