摘要：The purpose of the present study was threefold. First, to see if concordancing materials presented through data-driven learning (DDL) have any effect in the teaching/learning collocation of prepositions. Second, to find out if knowledge of collocation of prepositions could differentiate among the different levels of EFL learners' proficiency.
Third, to determine the extent to which Iranian EFL learners' knowledge of collocation of prepositions is affected by their L1. To this end, 200 senior English majors studying at three universities in Shahrekord served as the participants of this study. A Michigan Test of English Language Proficiency was used to determine the participants' level of proficiency. The subjects were then randomly divided into two groups. One group underwent the conventional treatment on prepositions and their collocational patterns. The second group received treatment through the DDL instruction that was based on concordancing lines. Two completion tests on collocation of prepositions were administered as the pre-test and post-test to check the effects of the treatments. The obtained data were then submitted to different statistical analyses such as analysis of variance (one-way ANOVA), and post hoc comparison using the Scheffe test. The results of the study yielded the following results. First, the DDL approach proved to be highly effective in the teaching and learning of collocation of prepositions. Second, learners' performance on collocation of prepositions was shown to be positively related to their level of proficiency. Third, the analysis of errors of collocations indicated that Iranian EFL learners tended to carry over their L1 collocational patterns to their L2 production.
