The concept of social presence is defined as the ability of learners to identify the learning community, have a sense of belonging to the community and communicate purposefully in a learning community. The reason for emphasizing the social presence of online learning is that online and virtual learning experts believe that social constructivism is an important factor in promoting interpersonal communication and the quality of learning. Given the importance of social presence as an influential variable in the process of virtual education, it is necessary to pay more attention to this issue and its predictors. In this regard, the present study aimed to provide a causal model for predicting social presence based on cognitive presence mediated by the online learning atmosphere. Participants included 265 students of online courses of Payame Noor universities in North Khorasan province in the academic year of 2009-2010 who were selected by cluster random sampling method. In order to measure the research variables, questionnaires of cognitive presence, social presence and online learning atmosphere were used. Amos software and path analysis method were used to evaluate the proposed model. The results showed that, 1-According to the above findings, the proposed model in the RMSEA index (root mean square of estimation errors) does not fit well, so the model was modified by correlating latent variable errors and The results showed that the final model has a good fit; 2-Cognitive presence has a direct, positive and significant relationship with social presence (P≤0.05 and β=0.62); There is a direct, positive and significant relationship between cognitive presence and online learning (P≤0.05 and β= 0.14) and also a direct relationship between online learning atmosphere and social presence is positive and significant (P≤0.05 and β=0.32); 3-In the indirect way, with the presence of mediator variables, the relationship between cognitive presence and social presence was still significant and the online learning atmosphere absorbs part of the effect of cognitive presence on social presence and mediates this relationship in part .

Introduction: Of particular global concern is the coronavirus disease of 2019 (COVID-19) outbreak. All Persian versions of COVID-19 measures assess the intrapsychic aspects of it, and there is a crucial need to measure the intergroup aspects of this pandemic. Aim: The current study aims to validate the Persian version of COVID-19 attitudes and behaviors in the Iranian sample. Method: The participants included 250 people from all over Iran in cyberspace who were selected availability (177 men and 73 women). They voluntarily participated in the study by filling out questionnaires that were made available through Google Forms and then disseminated online. Results: The ACAB scale had satisfactory reliability and validity according to content, face, and construct validity tests except for the first subscale (social distancing adjustment). Consequently, confirmatory factor analysis supported the ACAB with 12-item and three subscales. Therefore, three subscales remained, including self-prioritization, prosocial behaviors, and belief in conspiracies, and social distancing adjustment was eliminated because the factor loading values of its items were less than 0.4. Conclusion: Results indicated that the ACAB is a reliable and helpful tool in research, especially for governmental surveys to understand why people do not cooperate in vaccination or prosocial behaviors.

The purpose of this research was to explain critical thinking in electronic education. The qualitative research aimed at analyzing the importance of critical thinking skills in improving students' virtual education learning with a descriptive-interpretive approach sought answers to the following 2 questions: 1- How do students describe their learning experiences with critical thinking in virtual education? 2- What changes has the critical thinking skill made in learning the virtual education of students? The data collection tool was an open-ended interview, with 12 of the 98 incoming student teachers, with targeted sampling and the research location of the Faculty of Teacher Education, Farhangian University of Ardabil, who had studied with virtual education. Analysis of the findings after implementing the experiences and interviews of the students and the components obtained from the open and central and selective coding with 6 components (self-knowledge - spirituality - media literacy - receptivity to criticism and criticism - pluralism - cognition and metacognition) It led to the conclusion of the following 3 themes according to the elements of the national curriculum and the goals of education as follows: 1- Communication with oneself 2- Communication with God 3- Communication with creation It could be used in educational systems and the positive and negative consequences in learning and education in order to be successful in learning, and it is necessary that the virtual learner is not limited to education, but must be a critical thinker or acquire educational skills and abilities during his education.
