摘要：AbstractWidespread use of mobile and wireless devices in education has led to revolutionary changes in the way teachers teach and learners learn. Due to their pervasiveness, mobile phones are considered as being potentially valuable learning tools. However, students’ personal use of mobile phones and their apps for learning benefit is still open to research. This study thus investigated the impact of mobile dictionary use on language learning. Thirty-four lower-intermediate language learners participated in a pretest-posttest quasi-experimental study. They were divided into two groups (17 in each group) based on their choice to work with a mobile dictionary or a printed one for their language course. During the course, the experimental group used a dictionary installed on their mobile phones to do all their activities. Meanwhile, the control group worked with the printed version of the same dictionary. A teacher-made achievement test was used as the pre- and post-test. The result showed that, while controlling for the entry level language ability, the experimental group outperformed the control group in the post-test. The finding of the study underscores the vital role mobile phones play in extending learning out of the classroom anywhere anytime.
