This research is a descriptive quantitative study. The research has several objectives: (1) to uncover the learning outcomes of descriptive text writing for 7th-grade students at SMPIT Al Ishlah through the utilization of poster media, and (2) to demonstrate the effectiveness of utilizing poster media in teaching descriptive text writing to 7th-grade students at SMPIT Al Ishlah. The research design employed is a one-group pretest-posttest design, which is a quasi-experimental design. The population of this research includes all 92 students from 7th grade at SMPIT Al Ishlah, Kabupaten Maros. A sample of 32 students from the population was selected using purposive sampling, specifically students from class VII-C. Data for the research was collected using a test technique for both pretest and posttest activities, as well as documentation techniques. The instruments used for these techniques consisted of three components: a student essay test sheet used for the pretest and posttest, an observation sheet, and a documentation sheet. The collected data was then analyzed inferentially through tests for normality and homogeneity for the pretest data, and t-test for the posttest data. All inferential data calculations were conducted using the Statistical Package for the Social Sciences (SPSS) program. The results of the descriptive analysis showed that the average posttest score was higher than the average pretest score. This finding was further supported by the inferential analysis, which indicated that (1) based on tests for normality and homogeneity, the data were normally distributed and homogeneous, and (2) based on the hypothesis test, the significance value of 0.0001 was smaller than the alpha value (0.05), leading to the rejection of the null hypothesis (H0) and acceptance of the alternative hypothesis (H1). This indicates that the utilization of poster media is effectively employed in teaching descriptive text writing to 7th-grade students at SMPIT Al Ishlah.
