영어학습에서 모바일 러닝 환경이 지각된 유용성, 만족 및 영어학습성과에 미치는 영향에 관한 실증연구

The development of wireless internet and mobile device has created new learning method known as Mobile-Learning(m-Learning). As compared with e-Learning, m-Learning provides more mobility, flexibility and convenience than e-Learning. Learners can be access to learning materials and information through their mobile devices at anytime, anywhere. Prior researches have focused on either e-learning or descriptive aspects of m-learning in the various learning situation. However, an empirical research on identifying factors that determine user's satisfaction and performance of m- Learning, particularly English learner, has been a scant. Therefore, the main purpose of this study is to investigate the impact of key m-Learning environmental factors on English learner's psychological feelings of using m-Learning, as well as their satisfaction and performance. This study empirically tested the research model representing the casual relationships by using Structural Equation Model with 166 responses among variables, which include Self-Directed Study, Ubiquity, Contextual-Offer, Interactivity, Perceived Enjoyment, Perceived Usefulness, Satisfaction and Performance. Results provide evidence that support the tested hypotheses with exception of the casual relationship between Interactivity and Perceived Usefulness. The implications of the findings suggest a new theoretical work for future m-Learning research in various contexts and offers suggestions that the researchers and practitioners of m-Learning should consider regarding the development of m-Learning.
