The Effect of Teaching Formulaic Expressions Through Contrastive Lexical Approach on Iranian Pre-intermediate EFL Learners' Writing Skill

Abstract

This study aimed to investigate the effect of the contrastive lexical approach on Iranian EFL learners' writing skills. For this study, forty pre-intermediate students from a private English language institutes in Ahvaz, Iran were selected. Then, they were randomly divided into two equal groups of 20; one experimental and one control group. To have two groups of equal numbers, we used a block randomization sampling method. All of these students were female, ranging in age from 18 to 30. Their level of English language proficiency had already been determined by the Institute to be pre-intermediate. First, they were given a pre-test to determine their writing ability. Afterward, the experimental group received writing practices through the Contrastive Lexical Approach (CLA), during 14 sessions. Each session lasted for an hour and a half. The teacher sensitized learners in the experimental group towards the presence of L2 equivalents for L1 formulaic expressions, while the control group received an ordinary, traditional instruction, during which learners read texts containing the same formulaic expressions as for the experimental group without receiving any translation and were then asked to write about the same topics. At the end of the course, a post-test was administered to the two groups. Data were analyzed through independent and paired samples t tests after ensuring the normality of the data. Finally, to discover the power of the statistical tests, the effect size was also calculated. The study showed that using a contrastive lexical approach has a significant positive effect on Iranian EFL learners' writing skills. As the findings in this study propose, the writing skill can be improved through the use of a contrastive lexical approach. Teaching through a contrastive lexical approach, hopefully, gives the learners the chance to fathom their skillful writing competence, which requires the proper use of varied forms of structures and expressions and this, in turn, may sensitize them to know more about what language features to work on to increase their writing proficiency.
