Enhancing EFL Students’ Descriptive Writing Performance trough the Clustering Technique

Abstrak

The purpose of this study was to determine whether a significant difference existed between the writing achievement of students taught through the clustering technique and those instructed using conventional methods at the tenth-grade level of SMK Muhammadiyah Tawang Rejo. The population of this research included all tenth-grade students, totaling 38 learners. The sample was selected using a purposive sampling technique, ensuring that the chosen participants met specific criteria relevant to the study. This research employed an experimental approach, specifically utilizing a quasi-experimental design to compare the two instructional techniques. A writing test was administered as the primary instrument to measure students’ performance. The statistical analysis revealed that the t-obtained value of 2.946 exceeded the t-table value of 2.042, indicating a meaningful difference between the two groups. Additionally, the significance value for the two-tailed test was 0.00, which is lower than the predetermined significance level of 0.05. These results provided sufficient evidence to support the acceptance of the Alternative Hypothesis (Ha), while the Null Hypothesis (H0) was rejected. Therefore, the findings confirmed that the students who received instruction using the clustering technique achieved significantly better writing outcomes than those taught through traditional or conventional instruction. In conclusion, the study demonstrated that the clustering technique had a positive impact on students’ writing ability and proved to be more effective than the conventional method for the tenth-grade students of SMK Muhammadiyah Tawang Rejo.
