The Effect of Cooperative and Individualistic Instruction on Vocabulary and Pronunciation Learning: A Case of Low-Intermediate Iranian EFL Learners
Bibliographic record
Abstract
The present study was carried out in order to find out about the effect of two instructional programs, namelycooperative and individualistic instruction on the vocabulary and pronunciation improvement of low-intermediate EFL learners. The subjects were 50 students at the fifth grade of Mellal school aged 10-12 in Esfahan in Iran, who were randomly assigned to the experimental and control groups. The two selected groups were instructed over a period of ten weeks. For this purpose, a pretest-posttest experimental design was used. Prior to the treatment, a test for both vocabulary and pronunciation was developed, piloted, and administered to check the homogeneity of the participants. Then, the students‟ scores in the homogeneitycheck test were used as the pre-test score, too. For the treatment, the learners in the experimental group were instructed via cooperative technique whereas the learners in the control group received instruction according to a teacher-centered method following an individualistic-instructional approach. At the end of the study, the same test was administered to both groups as the post-test. Results suggested that both individualistic and cooperative instruction can enhance vocabulary achievement of Iranian lowintermediate EFL learners. However, no significant difference was found between the two groups regarding their vocabulary achievement. However, there was a significant difference between the two groups regarding their pronunciation achievement, and, thus, it was concluded that the application of collaborative methods in EFL classes can lead to an improvement in the learners‟ pronunciation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
