PENGARUH MODEL PROBLEM BASED LEARNING MELALUI PEER REVIEW TERHADAP KEMAMPUAN MENULIS TEKS NARASI SISWA KELAS X SMA NEGERI 2 MALINGPING

Abstract

This study aims to determine the effect of implementing the Problem-Based Learning (PBL) model through peer review on the narrative writing skills of Grade X students at SMA Negeri 2 Malingping. The study employed a quantitative approach with a quasi-experimental method involving an experimental class and a control class. The sample consisted of 61 students, comprising 31 students from class X-3 as the experimental group and 30 students from class X-4 as the control group. Data were collected through narrative writing tests administered as pretests and posttests. The data were analyzed using SPSS version 27, with the analysis techniques including the mean, standard deviation, and t-test.The results showed an improvement in narrative writing skills in the experimental group after the treatment. In the experimental group, the pretest scores ranged from 30 to 90, with a mean of 60.16 and a standard deviation of 15.518. After the treatment, the posttest scores increased, ranging from 55 to 95, with a mean of 78.39 and a standard deviation of 10.197. Meanwhile, the control group obtained pretest scores ranging from 30 to 85, with a mean of 58.67 and a standard deviation of 15.588. In the posttest, the control group's scores ranged from 55 to 95, with a mean of 74.83 and a standard deviation of 10.544.The t-test results showed a significance value (Sig. 2-tailed) of 0.009, which is less than or equal to 0.05. Therefore, the alternative hypothesis (H₁) was accepted and the null hypothesis (H₀) was rejected. These findings indicate that implementing the Problem-Based Learning model through peer review had a statistically significant effect on the narrative writing skills of Grade X students at SMA Negeri 2 Malingping. Thus, PBL through peer review may serve as an alternative instructional model for improving students' narrative writing skills.
