The Effect of Graphic Organizer Strategy on Improving Iranian Intermediate EFL Learners’ Writing Complexity

Writing by which students can be assessed plays an important function in the education process. hence, investigating the impact of graphic organizer strategy on improving iranian intermediate efl learners’ writing complexity was the main goal of this study. forty female intermediate efl learners were selected as the participants of the study based on convenience sampling and the results of the preliminary english test. after that, they were randomly assigned to two experimental and control groups. to assess the initial writing complexity of the participants, both groups were given a pre-test prior to the treatment. after employing traditional method in the control group and the graphic organizer strategies in the experimental group, both groups received a post-test to examine the effect of the treatment. the design of the present research was quasi-experimental. to analyze the obtained data, the researchers conducted an independent samples t-test, and to examine the progression in the experimental group, a paired samples t- test was employed. the findings of the study indicated that graphic organizer strategies improved the learners’ writing complexity. the results have some implications for efl/esl teachers, students, test and materials developers, and syllabus designers.
