Computer-mediated Technology and Vocabulary Learning. The Effect of Explicit Instruction of Clustering New Words through PowerPoint

      Аннотация: Vocabulary learning through computer-mediated technology is an ever-growing trend in EFL context. Based on recent studies,the application of computer-mediated technologies might improve internalization and retrieval by learners. This study used a combination of strategies via PowerPoint to solve the problem of vocabulary learning and recall. Seventy five Iranian intermediate EFL learners were sampled to learn and retrieve some new words. The words were highlighted and hyperlinked to their first language translation (for experimental group1) and to their English definition (for experimental group2) in a PowerPoint program. The control group learned the same words via a handout rather than the program. Three tests were given to the groups. Based on t-tests,the program enhanced vocabulary learning of the experimental groups. According to One-way ANOVA, there was no significant difference between the experimental groups but between the experimental groups and the control group in vocabulary learning and recall.The study aimed at inviting learners, teachers, teacher educators, practitioners, and professionals to apply the strategies to improve vocabulary learning and recall of learner.
