Impact of an extended reality-powered mobile application: an experimental study in interpreting classes

Given the importance of traditional teacher-led language laboratory instruction in interpreter training with reference to real-life practices for developing interpreter competence, XR MALL–a pioneering mobile-assisted language learning application powered by extended reality (XR)–was developed to address the need of authentic contexts for practising interpreting between Chinese and English in a three-channel mode: listening, speaking, and visual dimensions. This study investigates the effectiveness of XR MALL on the learning outcomes and experiences from the students’ perspectives based on a quasi-experimental design with a theoretical framework combining a constructivist approach and an interpreter competence model. Respondents’ perceptions and views on their interpreter competence as well as their cognitive and affective development were elicited by closed- and open-ended questions in pre- and post-intervention surveys and tests. Positive quantitative findings and qualitative responses were observed from pre- and post-intervention surveys, suggesting significant improvements in the experimental group's interpreting, strategic, psycho-physiological competencies, and language proficiency in comparison to the control group. The experimental group rated significantly higher in cognitive and affective development and had positive attitudes toward incorporating XR MALL into interpreting classes. The findings illustrate that XR and mobile technologies enhance students’ positive perceptions of learning experiences and their sense of achievement.
