Mobile learning is an emerging field of research and practice across educational institutions and workplace. More and more students have access to smartphones, tablets and other mobile devices. This study was aimed to better understand how prospective teachers of English language teaching (ELT) use mobile technology for learning and how they want to use mobile devices for teaching in the future. A total of 144 student teachers enrolled in an ELT department at a major state university participated in the study. Based on descriptive statistics, the findings revealed that a great majority of the participants currently own and use phones, particularly internet capable ones, MP3 players, and tablets. Nearly four in ten prospective English teachers plan to buy a tablet (e.g., iPad), three in ten intend to purchase smartphones (e.g., iPhone), and one in ten is likely to purchase an e-book reader (e.g., Kindle.) over the next year or two. Further, nearly all the participants stated that despite the impediments, they wanted to use mobile devices in their English lessons and teaching regularly in the future. They believed that the biggest barriers that might moderate on the appropriate application of mobile devices in ELT included the great versatility in device types, pedagogical justifications, administrational factors, lack of training, and lack of devices due to financial restrictions. Some recommendations are also provided.
