Comparing the Impact of Audio-Visual Input Enhancement on Collocation Learning in Traditional and Mobile Learning Contexts

: This study investigated the impact of audio-visual input enhancement teaching techniques on improving English as Foreign Language (EFL) learnersˈ collocation learning as well as their accuracy concerning collocation use in narrative writing. In addition, it compared the impact and efficiency of audio-visual input enhancement in two learning contexts, namely traditional and mobile learning contexts. First, ۱۲۰ homogenous intermediate EFL learners were randomly divided into four groups, two experimental and two comparison groups. Next, two pre-tests, a collocation and a paragraph writing test, were administered. The experimental groups received enhanced target collocations through input enhancement teaching techniques while in the comparison groups the “unenhanced” collocations were taught through conventional simple vocabulary teaching method. After the treatment sessions, the researcher administered two post-tests including a collocation and a paragraph writing. As the data analysis suggested, with regards to the first research purpose, audio-visual input enhancement positively affected EFL learners' collocation learning and enhanced their accuracy concerning collocation use in narrative writing. Regarding the second purpose of the study, the results revealed that, in comparison to traditional learning context, audio-visual input enhancement teaching techniques were significantly effective in mobile learning context in terms of collocation learning. The efficiency of audio-visual input enhancement teaching techniques was not significantly different between the experimental groups in the two learning contexts in terms of enhancing EFL learners’ accuracy concerning collocation use. The findings of this study can create awareness for second language teachers and learners about the critical and beneficial role of input enhancement and mobile assisted language learning in successful language acquisition and learning.
