Abstrak

This research aims to determine the effect of the project-based learning model on students' ability to write expositions in class XI high school students. This research is quantitative research using the True Experiment method. The population in this study were all class XI students of SMA Negeri 2 Tanjungbalai, totaling 252 students. Determination of the sample using the Cluster random sampling technique. Based on this technique, a sample group was obtained with a sample size of 62 students, namely the Experimental Group with a sample size of 31 students and the Control Group with a sample size of 31 students. Data collection techniques use tests, namely pre-test and post-test. The data collection process involves assigning students to work on Exposition questions. Before analyzing the data, a normality test was first carried out. The results of the research show that there are differences in the ability to write exposition questions for class students who use the project-based learning model, and those without using the project-based learning model. This difference is shown from the results of the independent sample t-test, namely tcount=6,818, ttable 2.000, with a df value of 60, so the hypothesis testing criteria for this research is the Tcoun > Ttable, so the hypothesis value (HO) is rejected, and the alternative hypothesis (Ha) is accepted. This proves that there is a significant effect of the project-based learning model compared to no conventional learning model on the writing ability of class XI students at SMA Negeri 2 Tanjungbalai for the 2023/2024 academic year.
