This study was an endeavor to investigate the impact of Student Team Achievement Divisions (STAD) on Iranian secondary school EFL learners’ overall achievements and creativity. To fulfill the purpose of the study, 142 EFL students were selected based on their performance on the Oxford Quick Placement Test (OQPT). The students were divided into experimental groups receiving treatment through the STAD model of cooperative learning and the control group devoid of the stated treatment. To recognize the entry behavior pretests were run. The same educational content was taught to both EG and CG during an educational term. To disclose the effect of treatment, a creativity posttest similar to pretest but in reshuffled order in options and items, and also an achievement posttest within the content taught were administered to the students in both groups at the end of the instruction. Furthermore, the mean scores of achievement and creativity tests were compared through an independent samples t-test, and one-way ANCOVA respectively. The outcomes showed the rejection of the both null hypothesis consequently concluding that cooperative learning had a significant effect on the overall achievement of Iranian EFL learners, and creativity.

This study investigated the impact of cooperative learning on Iranian high schoolEFL learners’ critical thinking and motivation. To this end, 142 EFL students were selected based on their performance on the Oxford Quick Placement Test (OQPT), and divided into two heterogeneous experimental groups (EG) receiving treatment through STAD model of cooperative learning, and two control groups (CG) without any treatment. To recognize the entry behaviors of the participants, pretests were run. Then, the same educational content was taught to both groups during an educational term. Furthermore, in order to disclose the effect of treatment, a critical thinking post-test similar to the pretest but in rearranged order in options and items, and a motivation post-test were administered at the end of the instruction. The results obtained from the statistical analysis of the scores showed that cooperative learning has a significant effect on the critical thinking and motivation of the participants. The findings of the study are beneficial for EFL learners to improve their small group capabilities.

Since students are required to prepare their papers in well-organized written works, it is important for academic learners to have a good command of writing skill. One of the methods gaining a reputation in enhancing students’ performance in language teaching is cooperative learning. This study intends to examine the effect of one of the CL techniques on enhancing upper-intermediate EFL learners’ descriptive writing ability. Fifty participants of this study were assigned into two groups. First, Nelson general proficiency test was administered to make sure both are homogeneous in terms of general proficiency. Then, a writing pre-test was given to both groups to examine if they possess the same writing proficiency. Analysis of both Nelson and writing pre-test showed that both groups were at the same level at first. The experimental group received treatment using Student Teams Achievement Divisions (STAD) as a cooperative learning technique while the routine teaching method was implemented to the control group. After carrying out the treatments for 16 sessions, the writing post-test was given to both groups. The results rejected the first null hypothesis and showed STAD was efficient in increasing students' writing ability. The second null hypothesis was supported since the p value for this test was 0.74 and higher than 0.05 meaning males and females were similar in their performance. This study has implications on teaching and learning descriptive writing. This study also indicates that STAD is an effective alternative method and can be utilized by teachers to enhance the mastery of writing skill.

This study was an attempt to investigate the comparative impact of Student Teams Achievement Divisions (STAD) and Think-Pair-Share (TPS) on EFL learners’ listening. Accordingly, 60 female EFL learners selected from a larger group of 90 learners based on their performance on a sample piloted Preliminary English Test (PET) who studied at a language school in Tehran were randomly divided into two experimental groups. Both groups demonstrated homogeneity in terms of their listening at the outset. The same content was taught to both groups during 15 sessions with one experimental group undergoing STAD while TPS was used in the other group. At the end of the treatment, another sample PET listening section was administered to both groups. The result of the independent samples t-test run on the participants’ mean scores on the posttest revealed that the TPS group significantly outperformed those in the STAD group. These findings have certain implications which are discussed at length in the paper.

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.
