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.
This paper investigated the effect of PowerPoint Presentation on Iranian EFL learners Vocabulary in Chaharmahal Va Bakhtiari province. To this end, 100 Iranian high school EFL learners were selected based on their performance on PET. Then, the participants were randomly assigned into two groups (experimental and control).A pretest of vocabulary consisting words extracted from their text book was administered to determine their vocabulary knowledge prior to the treatment. Ten categories of word families were selected out of the students’ text book. Afterwards, some PowerPoint presentation slides including synonyms, antonyms, parts of speech, collocations, idioms, inflections, and relevant images were designed. The word categories were taught to the experimental group using PowerPoint slides while the same words were instructed to the control group without using PowerPoint slides. To uncover the effect of treatment, a posttest similar to pretest but in reshuffled order in options and items was administered. An independent- samples t-test was employed for the analysis of the data. The results showed that there was a significant difference between experimental and that of control groups’ performance in that experimental group`s participants outperformed those of the control group. The study provides implications for language teaching pedagogy, curriculum developers, English language teachers and tutors.
