Unleashing the Power of Engage Virtual Reality Learning App: A Syntactic Complexity Boost in Intermediate EFL Students' Oral Performance

Abstract In light of the growing enthusiasm in harnessing virtual reality (VR) for educational purposes, this study explores the effectiveness of integrating the Engage Virtual Reality Learning App to enhance the syntactic complexity of oral performances among intermediate EFL students. A cohort of thirty intermediate EFL students was enlisted, divided into an experimental group of 15 and a control group of 15. Initially, the groups underwent a homogeneity assessment utilizing the Preliminary English Test (PET). During the intervention phase, the experimental group utilized the Engage Virtual Reality Learning App for speaking practice, while the comparison group received conventional instruction devoid of VR-based components. The analysis employed descriptive statistics for mean scores and standard deviations, supplemented by a one-way ANCOVA analysis to examine group performance and evaluate the impact of the treatment. The results unveiled a significant enhancement in the oral proficiency of the experimental group in terms of syntactic complexity, underscoring the affirmative influence of integrating the Engage Virtual Reality Learning App. These findings underscore the potential of VR-based instruction to augment authentic language experiences, foster sociocultural learning, stimulate cognitive engagement, yield affective benefits, and contribute to overall language acquisition among intermediate EFL learners.
