ABSTRACT
This article reported on a study of development and evaluation of the Virtual Go Mode feature embedded in a VocabGo app to enhance primary students' vocabulary learning engagement. A total of 15 primary students in Hong Kong participated in this evaluation study for one week. Both quantitative and qualitative data were collected and analysed. The results showed that students' vocabulary learning engagement was high when using the Virtual Go Mode. It is suggested that future research focus on empirical studies in designing and implementing virtual location-based tasks supported by AR technologies in class to provide opportunities for students to practice and consolidate newly learned words and enhance their learning engagement in the post-COVID-19 pandemic.
