This is shows that there were improvement of students vocabulary. Altough there were students still had got poor classification but researcher concluded it depends of students pace in After all the data were obtaied, the data were tested using the Normality test before to the t-test. A statistical method for figuring out whether quantitative data is regularly distributed is the normality test. The purpose of this test is to confirm that the research sample is drawn from a population that is regularly distributed. The normalcy test is a need that must be fulfilled prior to the researcher conducting the hypothesis test, according to Adu et . The experimental group's pre-test and post-test findings are included in the data for this study. If the obtained significance value (Sig. ) is higher than the established significance level of 0. 05, the assumption of normalcy is deemed satisfied. The Shapiro-Wilk test was used to perform the normalcy test in this study. The tiny sample sizeAiless than 50 samplesAiled to the selection of this test. Table 4 Test of Normality English Language Education Department Bosowa University THE ACADEMIC Journal of English Language Education Volume 10 No. 1 June 2025 ISSN: 2528-3677. E-ISSN: 2988-408X The result of the normality test presents in the table 4. 6 the outcome of the normality assesment for studentsAo pre-test and post-test data, based on the Shapiro-Wilk normality test, which states that if the significance is greater 05 the data is considered normally distributed. The analysis results shows that the significance value of the pre-test was 0. 270, and 0. 373 for post-test significant value. Both the significance values of the pre-test and the post-test values were greater than 0. 05, therefore, the data were normally Table 5 Paired Samples Statistics The table above shows the results of the analysis of the pre-test and post-test scores. The mean score of the pre-test is 54. 45 with a standard deviation of 15. Meanwhile, the mean post-test score is 73. 23 with a standard deviation of 14.

In this research, the null hypothesis (HCA) stated that the use of the Quizlet application does not improve the English vocabulary mastery of seventh-grade students at SMP Tujuh Lima Makassar. Meanwhile, the alternative hypothesis (HCA) stated that the use of the Quizlet application can improve the English vocabulary mastery of students in the same class. The acceptance or rejection of the hypothesis is determined by looking at the two-tailed significance value (Sig. 2-taile. If the value is less than 0. 05, then HCA is rejected and HCA is accepted. Based on the results of the analysis in the table above, a significance value (Sig. 2-taile. 000 was obtained. This value is lower than 0. shows a significant difference between the pre-test and post-test results. Thus, the alternative hypothesis (HCA) is accepted and the null hypothesis (HCA) is rejected. These results show that using the Quizlet application can improve the English vocabulary ability of seventh-grade students at SMP Tujuh Lima Makassar DISCUSSION The findings from the observation shows that the use of interactive features in the Quizlet application provides opportunities for students to practice memorizing and mastering vocabulary through learning activities combined with educational games.
