Abstract:

This study investigated the efficacy of explicit vocabulary strategies in enhancing the academic performance of senior high school students at the Southeast Asia Institute of Trade and Technology. Employing a descriptive correlational design, quantitative data (pre- and post-tests) and qualitative data (student questionnaires, teacher observations) were collected from 80 students. The study examined the impact of various explicit vocabulary strategies, including direct instruction, peer teaching, writing activities, repeated exposure, technology integration, and contextual learning, on vocabulary acquisition, student engagement, reading comprehension, writing skills, and vocabulary retention. Results indicated a significant positive correlation between the implementation of explicit vocabulary strategies and improved student performance. Students demonstrated significant gains in vocabulary knowledge, as measured by pre- and post-test scores across three lessons. Data supported these findings, with students reporting increased engagement, improved comprehension and writing skills, and enhanced vocabulary retention. The study concludes that explicit vocabulary instruction is highly effective in improving senior high school students' academic performance. The research recommends the development of instructional materials—including a vocabulary strategy guide, interactive word walls, and engaging games—to support teachers in implementing these effective strategies.
