AR Videos as Scaffolding to Foster Students' Learning Achievements and Motivation in EFL Learning

Augmented reality (AR) is capable of providing students with proper situated scaffolding via overlaying rich media objects on the real-world learning context. This paper examines the potential of AR to address existing problems with insufficient scaffolding in video learning materials for English as a foreign language (EFL) learners. Thus, an AR video-enhanced learning (ARVEL) method was designed to assist students' EFL learning. Furthermore, an experiment was carried out to investigate the influences of the implemented method on students' EFL learning outcomes. The experimental results displayed that the ARVEL method significantly improved the students' learning achievements and intrinsic motivation, and enhanced their satisfaction with EFL learning, compared to the students learning EFL with conventional video-based learning.
