Abstract:
The objective of this study is to ascertain the notable impact of utilizing the
Busuu application on pupils' vocabulary. The Busuu program is an English
language learning tool designed to enhance spelling, vocabulary, speaking skills,
and word comprehension abilities.
This study is conducted using experimental methods. The research samples
consisted of an experimental class and a control class. The population for this study
consists of eighth-grade students enrolled at SMP Muhammadiyah 57 Medan
during the 2023/2024 academic year. The sampling method employed was
purposive sampling. The test is multiple-choice. The research uses a vocabulary
exam as its primary tool. The data, comprising 25 items, were analyzed using paired
difference tests, specifically the Paired sample t-test, in SPSS version 27.
The research findings indicate a disparity between the pre-test and post-test
scores in the experimental class, with an average score of 65 and 76.54,
respectively. Consequently, utilizing the Busuu program has resulted in a notable
augmentation of kids' vocabulary. The analysis results indicate that the utilization
of the Busuu application has a statistically significant value of 0.001, which is lower
than the commonly accepted threshold of 0.05. This data suggests a substantial
impact on the utilization of the Busuu application. Thus, the null hypothesis (H0)
is refuted, and the alternative hypothesis (Ha) is affirmed.
