The Correlation Between the Intensity of Playing Roblox on Vocabulary Size of Efl Secondary School Students

This research explores the relationship between Roblox gaming intensity and the vocabulary size of EFL secondary school learners in Palangka Raya. The study was driven by persistent challenges in vocabulary mastery, low student engagement in conventional learning methods, and the growing relevance of digital platforms as authentic sources of language exposure. Employing a quantitative correlational design, the investigation involved 222 junior high school participants. Data were obtained through a Roblox Intensity Questionnaire adapted from Suryadi et al. (2024) and a receptive Vocabulary Levels Test based on Webb et al. (2017). Pearson correlation analysis revealed a significant positive association between the frequency of Roblox play and students’ vocabulary size (r = 0.244, p < 0.001). Regression analysis further demonstrated that Roblox intensity accounted for 5.9% of the variance in vocabulary outcomes, with each incremental rise in gaming intensity predicting a 0.242-point increase in vocabulary scores. The findings underscore the pedagogical potential of leveraging commercial gaming platforms such as Roblox to foster vocabulary growth within EFL learning environments.
