Vocabulary is a crucial element in language learning and communication. However, many seventh-grade students of SMPN 1 Banjarmasin still struggle with limited English vocabulary, which hinders their overall English proficiency. To address this challenge, digital gamification is seen as a promising method to boost student engagement and vocabulary achievement. Therefore, this study aimed to investigate whether there is a difference in the vocabulary achievement between the students who use Blooket and students who use Wordwall among seventh-grade students of SMPN 1 Banjarmasin.

This research employed a quantitative approach with a quasi-experimental design involving sixty seventh-grade students selected through purposive sampling. The students were divided into two groups: the experimental group used Blooket, while the control group used Wordwall. Data were collected through pre-tests and post-tests to measure students’ vocabulary achievement before and after the treatment. The collected data were analyzed using SPSS version 27, specifically employing the Mann-Whitney U test to determine the differences between the two groups.

The findings indicate that there is a significant difference in students’ vocabulary achievement between the two groups, with students in the experimental group (Blooket) achieving higher post-test scores (mean = 87.750) than those in the control group (Wordwall) (mean = 82.333). This is supported by the Mann- Whitney U test, which indicated p < 0.05 (p = 0.039), which leads to the rejection of the null hypothesis and the acceptance of the alternative hypothesis. The results confirm that Blooket has a more significant positive impact on students' vocabulary achievement compared to Wordwall.

Based on these findings, several recommendations are proposed for educational practice and future research. English teachers are encouraged to use Blooket as a digital learning tool to support vocabulary learning. Future research may explore the use of other gamified platforms with similar designs to examine their impact on vocabulary learning in different classroom contexts.
