The integration of technological instruments into education is no longer an innovative approach nowadays. In many contexts, the use of mobile devices to reinforce learning and teaching activities has become a vital part of both formal and informal processes. However, the impact of digital devices on learning still remains a discussion. Consequently, this study aims to investigate 1.) the attitudes of high school students toward electronic device use on English learning and 2.) the influence of learning devices on elevating learner autonomy. The current study suggests that English learners in high school may benefit from utilizing electronic devices; for example, learner autonomy would be maximized through clear direction and screen time management. In order to explore the possibilities of motivational factors in a Taiwanese context for English learners, this research study can serve as a comprehensive approach that addresses the gap in educational studies. The results from the current work indicated that English learners in high school may develop increased learning motivation when allowed to utilize electronic screen devices under guidance and appropriate time control. This finding supports prior research on the promotion of motivation through mobile devices in foreign language classes.
