Keywords: digital media, vocabulary acquisition, vocational high school, quasi-experiment, English language learning Mastery of technical English vocabulary is essential for vocational high school students to meet global industry demands. This study aims to examine the effectiveness of digital learning media on vocabulary mastery among tenth-grade Computer and Network Engineering students at SMK AL-KYAI Sukosewu. Using a quantitative approach with a quasi-experimental design, the study involved two groups: the experimental group (digital media) and the control group (conventional methods). Pre-tests and post-tests were used to measure vocabulary improvement. The Shapiro-Wilk normality test showed that the data were normally distributed (p > 0.05), and Levene’s test indicated homogeneous variance (p = 0.197), allowing for parametric analysis. Paired samples t-tests showed significant improvement in both the experimental group (Mean difference = -17.560; t = -37.995; p = 0.000) and control group (Mean difference = -9.120; t = -27.365; p = 0.000). The independent samples t-test revealed a significant difference in post-test scores (t = -2.830; df = 48; p = 0.007), with the experimental group scoring higher (70.88) than the control group (63.28). These findings indicate that digital learning media is more effective than conventional methods in improving students’ vocabulary mastery. The results underscore the importance of integrating technology into language learning, particularly in 21st-century vocational education, as digital media not only enhances learning outcomes but also enriches students’ interactive and meaningful learning experiences.
