Abstract
Because of the widespread use of digital technology, many EFL students access various types of technologies that help them acquire English vocabulary beyond formal classroom learning. This paper aims to explore Saudi EFL learners' attitudes towards informal digital learning of English vocabulary (IDLEV) outside the academic requirements as well as their practices of IDLEV beyond the classroom. To answer the research questions of the study, the researchers recruited 80 Saudi EFL students from the University of Bisha, Saudi Arabia, to respond to a self-reported questionnaire. The study found that Saudi EFL students have positive attitudes towards informal digital learning of English in improving their vocabulary. Results also reveal that the participants tend to use different technologies to learn English vocabulary in informal settings. The study found that receptive activities are more commonly used than the productive activities. The study found a significant correlation between learners' attitudes and practices. The implications of the study and recommendations were presented accordingly.
