lexical collocations

This study examined the effects of input-oriented and output-oriented tasks with different involvement load indices on Iranian EFL learners' comprehension and production of lexical collocations. To achieve this purpose, a sample of 180 intermediate-level EFL learners (both male and female) participated in the study. The participants were in six experimental groups. Each of the groups was randomly assigned to one of the experimental conditions, namely input-oriented tasks with involvement load 1 (True-false), 2 (Matching), 3 (Multiple-choice), and output-oriented tasks with involvement load 1 (Short response), 2 (Fill in the blanks), and 3 (Sentence formation). At the end of the treatment period, the researchers administered a 40-item test in multiple-choice format and a 40-item test in fill-in-the-blanks format to assess the participants' comprehension and production of collocations. The collected data were analyzed using two different two-way ANOVAs and a series of independent-samples t-tests. The results showed that the tasks with higher involvement load indices were more effective on both receptive and productive knowledge of lexical collocations. The results also revealed that output-oriented tasks were more beneficial than input-oriented tasks at all three indices of involvement load. These findings can have theoretical and pedagogical implications for language teachers, researchers, and learners.

It is widely acknowledged that collocations play a crucial role in second or foreign language learning by enabling learners to know more about language chunks and lexical strings. Although many studies have examined L2 learners’ collocational competence, comparatively less research has been carried out to probe into the effective instruction and exercises for enhancing the acquisition, retention, and production of lexical (e.g. make a mistake ) vs. grammatical ( on purpose ) collocations. Therefore, the present study attempted to explore the effect of L2 definitions, fill-in-the-blanks, and sentence writing exercises on the acquisition, retention, and production of lexical vs. grammatical collocations. The data were collected from 66 EFL participants who were studying English at a private language institute. First, an Oxford Placement Test (OPT) was given to homogenize the learners. Then, the participants were divided into three groups, each receiving one of the three different types of exercises including definitions, fill-in-the-blanks, and sentence writing exercises. Data analysis using multivariate ANOVA (MANOVA) indicated that learners who received the sentence writing treatment significantly outperformed those learners who received definition and fill-in-the-blank exercises in the acquisition, retention, and production of lexical vs. grammatical collocations. Moreover, fill-in-the-blanks could help the participants learn, retain, and remember both types of collocations significantly better than the L2 definitions. These findings have some pedagogical implications for learning and teaching lexical and grammatical collocations.
