The ability to master English is one of the most important things for students in
junior high school. Vocabulary mastery is important for students to succeed in
learning and mastering English. The main purpose of this research was to find out
whether or not there was any significant difference between students' vocabulary
mastery before and after being taught using the Memrise application. In this
research, the researcher used quantitative research. This research applied a pre
experimental design with a one-group pre-test and post-test. The sample in this
research consisted of 30 students. The technique of data analysis was using SPSS
27. The analysis results show that the instruments used in the research are valid and
reliable, as seen from the data results. After collecting the data from the pre-test and
post-test, the researcher calculated the students' pre-test and post-test scores and
calculated the students' mean scores. From the results obtained, it is known that
there is a difference in the mean score of pre-test and post-test scores. The mean
score of the students' pre-test was 69.166, while the mean score of the students' pre
test was 87,000. It means that The mean score of the students' post-test was higher
than the mean score of the students' pre-test. The researcher used SPSS to analyze
the t-test.The t-test aims to determine whether there is a significant difference
between before and after being taught using the Memrise application. From the
calculations, it showed that the value of Sig. (2-tailed) is 0.000. Thus, it can be
concluded that 0.000 < 0.05. It means that there is a significant difference between
pre-test and post-test scores. The researcher compared the t-test score and t-table
value. Based on the analysis, it shows that the t-test score is 11,128, and the t-table
value is 1,699. It means that the t-test value is higher than the t-table. Thus, it can
be interpreted that the alternative hypothesis (Ha) was accepted the null hypothesis
(Ho) was rejected. It can be concluded that there is a significant difference in
students' vocabulary mastery before and after using the Memrise application.
Therefore, the Memrise application is suitable to use as a media for learning and
teaching English vocabulary.
