This study examined the effects of cooperative learning techniques (CLT) on vocabulary achievement of reflective/impulsive Iranian EFL Learners. From among 130 students at Fajr institute in Dehdasht, Kohkiloyeh and Boyer Ahmad Province, Iran, 90 participants were selected based on their performance on the Oxford Placement Test (OPT). The participants were then divided into two experimental groups (comprising reflective learners and impulsive learners) and one control group labeled as conventional instruction (CI) group. The instrument used to divide the participants into reflective and impulsive groups was the Eysenck’s (1990) Impulsivity Questionnaire. The experimental groups were taught with the student team achievement division (STAD) technique, while the control group was taught through the traditional method for ten weeks. To measure the vocabulary knowledge of the learners in different groups at the beginning and at the end of the experiment, a pretest and a posttest, each consisting of 40 items on new English words based on their book were used. Independent-Samples and paired-samples t tests were used to determine whether there were significant inter- and intra-group differences. The statistical analysis of the results showed that the experimental groups (reflective and impulsive) performed better on vocabulary achievement posttest than the control group (CI), and also it was revealed that reflective learners performed better on vocabulary achievement than impulsive learners. In sum, cooperative learning enhanced learners’ vocabulary performance, especially the reflective ones.

This study aimed to explore the function and frequency of textual metadiscourse markers (MDMs) in scientific English and Persian texts. Based on the qualitative and quantitative analysis of textual markers characterizing the selected genre, four different textbooks, two written in English and two in Persian were analyzed to identify the textual metadiscourse categories (including logical markers, code glosses, and sequencers) used in these texts and to determine the sociopragmatic differences existing in these languages, chi-square test was run and the findings suggested that textual MDMs were present in both English and Persian texts, but they differed in their frequency of occurrence. The contrastive comparison between the English and Persian texts revealed that the frequency of the textual MDMs was greater in the Persian texts. Therefore, it was concluded that such discrepancy could be attributed to the differing rate of explicitness in these two languages. The Persian writers were more interested in explicating their ideas for readers through the text via the use of textual markers (TMs) to a greater extent. It was further found that different factors may influence the use of MDMs, namely the culture, the writer's preferences, the text, and its genre. The implications could include the precaution that Iranian EFL writers ought to be advised to approximate their writing style, in terms of using MDMs, to that of native speakers of English while writing in English.
