Impact of Computer Concept-Mapping Instruction on Iranian EFL Learners’ Writing Performance: Complexity and accuracy in focus

چکیده

This inquiry investigates the impact of Computer Concept-Mapping on Iranian EFL learners’ writing complexity and accuracy. To this end, a total of 30 intermediate EFL learners aged 14 to 16 years were non-randomly selected, homogenized in terms of general proficiency, and classified into two treatment and control groups. Also, a pretest and a posttest on the participants’ writing performance were administered at the beginning and the end of the study.. Further, the ESL Composition Profile developed by Jacobs et al. (1981) was used as a criterion for evaluating the participants’ writing accuracy and complexity. The treatment group received computer-based concept mapping instruction, while the control group was instructed through conventional writing techniques. Then, the data obtained from the two groups’ pre- and posttests were comparatively analyzed through appropriate statistical tools. Parametric paired-samples and independent-samples t-tests as well as Pearson Correlation were also used to assess the inter-rater reliability indices of the participants’ writing tests. The results of data analysis indicated that computer concept-mapping instruction entails significantly better writing performance. This finding has implications for teachers and EFL programmers to use the latest methods and tools of instruction
