Abstract According to the importance of cooperative learning based on constructivism in better learning of the material, which has been demonstrated in many types of research, these techniques make students exchange information and opinions, help each other and get help. Cooperative learning and the conduction of constructivism in learning, increase group cohesion and enable students to interact with others and examine learning from all aspects. To conduct this research, 30 senior students with the age range of 16 to 18 and based on the English level proficiency test to ensure the same language level of them, were selected. Then the target students were divided into two experimental and control groups and the pre-test was taken from them. After grouping, English language teaching was done to the students of the experimental group based on constructivism and cooperative learning, and after a certain period (five weeks), a post-test was taken from them, and Stephen's cooperative learning questionnaire (2007) was given to the students, and then the data was collected and analyzed and T-Test, ANOVA, paired sample test were conducted. The most important findings, in the present research in the first stage, were the impact of constructivism and cooperative learning on English learning of the students who were trained and achieved the most effective cooperative learning techniques, and in the second stage recognized that students use the technique of group dynamics and then feedback and doing project work respectively based on Stephen's cooperative learning questionnaire (2007).

Due to the vital role of back channels in mutual understanding and their use in many aspects of language learning, the present study investigated the attitudes toward back-channeling in Iranian EFL online versus regular classes. The study was quasi-experimental in design, with interviews and recording of course sessions by ZDF Soft Screen Recorder and the voice Memos application in both classes to measure the duration of silence, TTT (Teacher Talk Time), STT (Student Talk Time), BC (Back Channels), and other activities such as TCS (Teachers' Code-Switching), SCS (Students’ Code-Witching), S (the time passed in silence). In doing so, two online classes included 30, two regular ones included 27, and four English teachers of the participants were randomly selected from the Kanoon Language Institute in Isfahan, Iran, to take part in the study. Learners received four and a half hours of instruction per week within the course period. In the next step, all the data gathered was analyzed and statistically addressed by using, IBM SPSS Statistics (Version 26) software. The results revealed back channels had positive effects on learners in both classes. Besides, teachers and learners had positive attitudes toward using back channels, however, in online classes, learners were more willing to use back channels. The findings of this study could be fruitful for improvement with well-designed materials and explicitly teaching back channels, which can provide opportunities for learners to express their emotions, and ideas, and enhance their strengths.
