Effects of Using Quizizz in Enhancing the Vocabulary Knowledge of English I Students at a Private University

The purpose of this study was to investigate the relationship between the Quizizz game-based platform and vocabulary knowledge. The researcher employed a quasi-experimental design with 241 first-year students enrolled in English I classes. A paired t-test statistical analysis was used to compare the pre-test and post-test results, while a 5-point Likert scale was used to assess the opinions of the students/participants. The pre-test was administered before introducing the vocabulary exercises using the Quizizz game-based online platform. At the end of the four-month intervention period, a post-test was conducted along with the attitudinal survey. The results showed a significant improvement in favor of the post-test, with a statistical difference of 0.01, indicating that students had substantially enhanced their vocabulary knowledge. Moreover, students' opinions on using Quizizz were overwhelmingly positive. These findings align with previous research suggesting that Quizizz effectively enhances vocabulary knowledge. Most importantly, based on the findings of the present research, it is recommended that Quizizz, a game-based platform be utilized to enhance vocabulary knowledge in English I classes at a private university.
