Abstract

Teaching and learning the English vocabulary pose considerable challenges for both EFL instructors and learners. However, vocabulary is a crucial component that must be mastered in the process of language acquisition. Thus, this study aims to investigate the substantial effect of captioned audiovisual debates in English on vocabulary acquisition among EFL learners. In this study, the researchers employed a quantitative method, specifically a one-group pretest-posttest research design, along with five perception-based questionnaires. The study was conducted at the English Department of Universitas Negeri Malang, East Java, with 39 undergraduate students in semesters 3 and 5 as the subjects of the study. The findings revealed that captioned audiovisual debate session material has a significant positive effect on the vocabulary acquisition of learners of English as a foreign language in the Universitas Negeri Malang, Indonesia. The t-test results indicate a remarkable difference in students' vocabulary knowledge performance between the pretest and posttest, in terms of both receptive and productive vocabulary skills, after watching the captioned debate video session. Meanwhile, the value of the t-test for receptive vocabulary knowledge was -5.082, and for productive vocabulary was -8.620, which was less than the alpha value of 0.05, presenting significance. It can be concluded that using captioned audiovisual debate can potentially enhance the vocabulary knowledge of EFL students.

Abstract

Improving EFL students' English vocabulary mastery always presents an excellent challenge for both EFL teachers and students. The purposes of this study are to investigate the effectiveness of the debate method on EFL students' vocabulary improvement and explore their perceptions of the implementation for mastering vocabulary. The researchers employed a pre-experimental design integrating mixed-methods, combining quantitative and qualitative methodologies. The study involved 20 undergraduate students from the English departments at the University of Antananarivo, Madagascar, in semester 5 in the 2025 academic year. Data were collected through vocabulary tests, questionnaires, and semi-structured interviews. The results indicate a statistically significant improvement in both vocabulary knowledge size, measured by the Vocabulary Level Test (VLT) with average score rising from 29.25 to 31.60, and productive vocabulary knowledge with average score increasing from 18.50 to 21.90, measured by the Productive Vocabulary Test, both with (p<0.05). Beyond enhancing undergraduate EFL students' vocabulary, the debate method is perceived as an effective, engaging, and motivational pedagogy that promotes self-confidence. The findings suggest that the debate is an effective strategy for teaching vocabulary mastery among undergraduate EFL students and is perceived as an engaging, confidence-building pedagogical approach.
