Results of computer assessment tests such as the CASEC, OPIc speaking test, and TOEIC indicated that blended and flipped lessons helped students to improve their overall English proficiency better than traditional approaches (McCarty et al., 2017). Use of mobile learning elements in the flipped classroom approach has a direct positive impact on overall student achievement (Oberer, 2015), which may cultivate more positive attitudes, interest and motivation compared with a traditional video-aided flipped pedagogical approach.
