The provision of scaffolding entails contingent assistance given to learners. Despite the proliferation of research on scaffolding, scant attention has been devoted to studying the modes of classroom interaction in fulfilling various scaffolding intentions in content-based instruction (CBI). To narrow the gaps, the present qualitative study embarked on an investigation of science teachers’ scaffolding in four modes proposed by Walsh (2006), namely managerial, classroom context, skills and systems, and materials modes. Four science teachers participated in this qualitative study, and 12 sessions of science classes were observed and analyzed deductively based on four classroom modes through conversation analysis (CA). The content analysis of the videotaped recordings indicated that managerial and materials modes were frequently used to enhance students’ comprehension and develop classroom interaction. The findings evidenced that pedagogical objectives were mostly related to cognitive structuring, contingency management, and direction maintenance requirements. Furthermore, the findings revealed that students’ engagement and involvement through recruiting interest was the only scaffolding intention employed in all four modes to involve students in the learning process. The findings can provide insights to teachers and teacher educators in the realization of distinct scaffolding intentions in various classroom modes by delineating the interrelationship between language use and teaching purpose.  

The conditions of the corona virus forced online education with LMS (learning management system). The main purpose of this research is to investigate the desirability of the quality of electronic education of Payam Noor University from the students' point of view of ISFAHAN LMS. The current research is a survey. The research tool was the USELEARN questionnaire and the checklist of the National Learning Association website. The statistical population includes all students who were studying at the Bachelor's degree and Master's degree (LMS) in the 2023 at Payam Noor University through electronic education. The simple random sampling method was used. The sample size was 384 students.Benson et al.'s and Salmon's models have been used to evaluate the quality indicators and components of Payam Noor University's electronic education. The average values of the ratings showed that the indices of "Professor", Information Technology" and "University Support" had the highest average and the most importance, and the index of "Contextual Factors" had the least importance. Based on the ratio test, the factors "teacher ", "electronic interaction” and “Access to facilities” are desirable factors.”University support and support" has been evaluated as a low desirability. There is a significant difference between the evaluations of the desirability of the quality of e-learning indicators and gender.Multivariate regression analysis showed that among the independent variables entered into the equation, the variables of the “Electronic lesson score”, “The teacher's interest and friendly behavior toward all students”, “Inviting students to use electronic education”, “Evaluation of face-to-face training” and” Ease of use of electronic education system” have the greatest impact on evaluating the desirability of electronic education that could explain 73% of the variance of the changes related to the dependent variable. The variables have been able to explain 73% of the variance of changes related to the dependent variable.
