An Attempt to Improve Grammatical Structure Retention: Impact of Computer-mediated Feedback on Iranian EFL Learners

Over the past years, the role of technology in education has been widely discussed. Despite it, ongoing debates persist regarding feedback in Computer-Assisted Language Learning (CALL). This study aims to fill gaps in the literature by assessing the effectiveness of focused computer feedback, including translingual feedback, correction requests, and repetitions, on short and long-term memory retention. It also seeks to determine the most effective approach for computer-mediated feedback in recalling language structures and gain insights into students’ attitudes towards it. To achieve these goals, a total of ۶۰ intermediate Iranian English as a Foreign Language (EFL) learners from Yazd University were randomly assigned to four groups, each corresponding to a different type of computer-mediated feedback. These groups, namely Meta-linguistic, Repetition, Clarification Request, and No Feedback groups, varied in specificity and format. After completing the computer-based assessment, the participants took two nearly identical multiple-choice tests three weeks apart to measure short and long-term retention, respectively. Furthermore, a questionnaire was meticulously designed and administered before and after the intervention to capture any shifts in participants’ attitudes towards computer-mediated feedback. According to the findings, the metalinguistic and repetition groups had the highest retention gains in comparison to the other groups. Furthermore, the results strongly supported the superiority of the experimental groups over the control group in terms of retention. The outcomes from the questionnaire also evidenced a positive enhancement in the participants’ attitudes towards computer-mediated feedback. Future research should explore the effectiveness of different combinations of computer-mediated feedback types. By studying the combined impact of two or more types of feedback on learners’ memory, valuable insights could be gained, moving beyond isolated feedback approaches.
