Grammatical accuracy has been controversial in L2 writing, and the utility of different types of corrective feedback has been enigmatic. Therefore, the present study attempted to explicate the impact of intensive versus extensive recasts through grammar-focused tasks on Iranian EFL learners’ grammatical accuracy in writing. To do so, 60 Iranian male and female EFL learners were assigned into two experimental groups (i.e., intensive and extensive groups) and one control group. After taking the Oxford Placement Test (OPT), the experimental groups received intended corrective feedback, while the control group did not receive any feedback. Then, the data was analyzed deploying both descriptive and inferential statistics. The results revealed the outperformance of experimental groups compared to the control group in the writing post-test. Also, it was concluded that extensive recast can improve EFL learners’ writing performance much better than intensive recast. The findings have some fruitful pedagogical implications for both teachers and materials developers.

The statistical population in the qualitative section of the study includes the electronic resources related to the research subject and, in the quantitative section, 60 distance education experts in the field of planning in virtual learning environments and virtual universities so that 36 of these experts were voluntarily selected as the study sample. Results: Content analysis results showed 4 dimensions and 16 criteria. The evaluation results of the experts also showed that interacting with the global network, the ease of online interactions with learners and other organizations, and the possibility of receiving electronic assignments or workbooks during the course, are regarded as the most important ethical characteristics of Courses online MOOC courses; security and privacy of individuals ought to be considered in their interactions, observance of the principles related to confidentiality with regards to the files or marks, with other participants through emails, chats, forums, etc.Conclusions: In these courses, the features of online courses and openness for enrollment are emphasized and predominant. Therefore, there is no need to get involved in new ethical features. Since the maximum current size of online classes is 60 students, various factors of these indicators such as learner agents, instructive organization, content, and teaching and learning environment ought to be accurately studied. Given that the capacity of learners may reach the limit of hundreds and thousands, the kind of considered ethics should be beyond the procedure implemented for online classes.

This research was conducted with the aim of identifying the characteristics of knowledge leaders in Tehran schools. Based on this objective, the study was conducted using a qualitative method. Data was collected through triangulation, including semi-structured interviews with administrators and teachers of all-girls secondary schools and knowledge management specialists, observation of schools and the study of relevant documents. Interviews were conducted with 28 people using criterion-based sampling method and 8 schools were observed in the areas under study using sequential sampling method. The Document of the Fundamental Evolution of Education and the Regulations for the selection and appointment of school administrators were also reviewed. The data was analyzed using thematic analysis. The characteristics of the school administrator as a knowledge leader were categorized into 3 main classes including: knowledge network builder, knowledge guardian and school knowledge flow facilitator, and 10 subcategories.
