Although previous studies have shown the benefits of graphic organizers in improving learners' vocabulary knowledge, scant attention has been paid to the possible differences in the effect of individually-developed, cooperatively-developed, and teacher-developed graphic organizers on intermediate L2 learners' vocabulary knowledge. The present study addressed this topic by examining 80 intermediate language learners. The participants were selected based on convenience sampling procedure and studied English in four classes. The learners in the conventional group received the translation/definition of the lexical items. Those in the teacher-generated were provided with the graphic organizers prepared by their teacher, and the participants in the other two groups made the graphic organizers either individually or cooperatively. The researchers employed Vocabulary Knowledge Scale as the pre-test, immediate post-test, and delayed post-test to examine the participants' vocabulary knowledge. The findings of this study indicated that the mean scores of the control group in the immediate and delayed post-tests were significantly lower than those of all graphic organizer groups. In addition, the cooperatively-generated graphic organizer group was significantly more successful than learner and teacher-generated graphic organizer groups, but there was no difference between the learner and teacher-generated groups.

Graphic organizers have been employed to facilitate second language learners' vocabulary knowledge development; however, the examination of the effects of these graphic organizer options on learners' collocation knowledge development has remained unexplored. This research investigated the effects of using teacher-generated, individually-generated, and cooperatively generated graphic organizers on Iranian English language learners' collocation knowledge. The present study examined these effects by studying 80 intermediate second language learners who were selected based on convenience sampling. The participants were assigned to four groups randomly. The collocations were provided on the board in the control group, and explanations were provided orally. In the teacher graphic organizer group, the teacher provided the learners with pre-filled graphic organizers with collocations. In the individually-generated group, the teacher provided the learners with a list of words in groups, and they had some minutes to generate their graphic organizers. In the cooperatively-generated group, the participants had some minutes to generate their graphic organizers cooperatively with their peers. Using a pre-test, immediate post-test, and delayed post-test, the researchers examined the effects of these conditions on learners' collocation knowledge. The findings showed that all graphic organizer groups were more successful than the control group in developing learners' collocation knowledge. In addition, the mean value of the participants’ scores in the cooperative group was significantly more than that of the teacher-generated and individually-generated groups, and there was no significant difference between the mean scores of the teacher and individual-generated graphic organizer groups.

Writing by which students can be assessed plays an important function in the education process. By considering this fact, investigating the impact of graphic organizer strategy on improving Iranian intermediate EFL learners’ complexity of written performance was the main goal of this study. 40 intermediate EFL learners were selected as the participants of the study on the basis of findings of Preliminary English Test. After that, they were randomly divided into two experimental and control groups. To assess the initial writing ability of participants, two groups were given a pre-test prior to the treatment. After applying traditional method to the control group and the graphic organizer strategies to the experimental group, both groups received a post-test to examine the effect of materials. To examine the effectiveness of the treatment, an independent samples t-test was conducted. To see the progression amount between pre-test and post-test of the experimental group, a paired samples t-test was also employed. The findings of the study indicated that graphic organizer strategies improved the learners’ complexity of written performance. The results have some implications for EFL/ESL teachers, students, test and materials developers, and syllabus designers.
