This study aimed to explore affordances and student perceptions of mobile-assisted language learning (MALL) in familiar environments to facilitate English as a foreign language (EFL) learning. Twenty-five undergraduate students participated in this study. Students learned EFL in class and then they worked on learning tasks in familiar learning environments outside of classroom. The students used resources from learning environments such as objects, people, situations, and scenarios to complete assigned tasks by describing them. They used a mobile learning system installed on Tablet PCs during learning process. We explored affordances and student perceptions of MALL in familiar environments to facilitate English as a foreign language (EFL) learning. The results showed that personal, specific, innovate, familiar, predictable, and meaningful were affordances of familiar environments for EFL learning. The students had positive perceptions of technology. Based on our results, several implications along with practical suggestions were prepared for EFL teachers and researchers.
