Objective: the present study aimed at investigating an already-proposed problem-based model of writing on iranian efl learners' writing skill.methods: in so doing, an experimental pre-test post-test control group study was designed. the participants of the study consisted of 60 female advanced efl learners who were randomly selected from eighty-eight learners who were passing an ielts preparation course at a private language institute. the study sample was randomly assigned into two groups (each consisting of 30 learners) namely, the experimental and the control groups. two samples of ielts writing task 2 were used for the purpose of measuring the participants' writing skill at the beginning (pre-test) and end (post-test) of the study. to analyze the data, normality test, descriptive and inferential statistics (i.e., analysis of covariance (ancova) test) was used.results: the results of data analysis showed that the proposed problem-based model of writing affects iranian efl learners' writing skill.conclusions: the findings have pedagogical implications for efl teachers and learners, and curriculum planners.
