Abstract

Grammar, particularly subject-verb agreement (SVA), played a crucial role in ensuring the structural accuracy of students’ writing. However, many students often found SVA difficult to master, which led to frequent errors in their sentences. In response to this problem, this research analyzed the effect of the Substitution Drill Technique as a teaching strategy to improve students’ mastery of SVA in writing descriptive texts. This study was conducted at SMP Cinta Rakyat 3 Pematangsiantar, focusing on eighth-grade students. The objective of this research was to investigate whether the Substitution Drill Technique had a significant effect on students’ ability to understand and apply SVA correctly in their writing. The design of this research was quasi-experimental with two groups: the experimental class taught using substitution drills and the control class taught with conventional methods. Both groups were given a pre-test and a post-test. The results showed that the experimental class’s mean score increased significantly from 51.74 in the pre-test to 84.52 in the post-test, while the control class only improved from 51.97 to 72.31. The independent samples t-test result confirmed a significance value of 0.000 (< 0.05), indicating that the Substitution Drill Technique significantly affected students’ mastery of SVA. Therefore, this study concluded that substitution drills were effective in enhancing students’ grammatical accuracy, particularly in applying subject-verb agreement in descriptive text writing

Abstract

Mastery of writing skills is very important. However, many students experience difficulties and challenges in improving their writing skills. This study was used to determine the effect of implementing the Problem Based Learning (PBL) model on the writing skills of class XI students of SMK Swasta GKPI 1 Pematangsiantar using a quantitative approach with a quasi-experimental design. This study took samples using a purposive sampling technique involving 60 students who were divided into 2 groups, namely the experimental group (XI TKJ A) which consisted of 30 students, and the control group (X TKJ B) which also consisted of 30 students. In this study, the experimental class received treatment using the Problem Based Learning (PBL) model and the control class with conventional methods. In this study, data were collected with pre-test and post-test and analyzed using an independent sample t-test where in the experimental class the mean pre-test value was 40,67 and post-test was 75, while the mean value in the control class on the pre-test was 35,33 and post-test was 50. After being tested using the t-test, a significance value (2-tailed) of 0.000 < 0.05 was obtained, so the Null Hypothesis (H0) was rejected and the Alternative Hypothesis (Ha) was accepted. This means that there was a significant increase in students in the experimental class who were given treatment. So, this shows a significant difference between the experimental class and the control class. Based on the research findings, it was concluded that the Problem Based Learning (PBL) model can significantly improve students' writing skills, especially in writing analytical texts with correct organization.
