The purpose of this research was to construct, validate and determine the reliability of online teaching satisfaction model among virtual course professors. For this purpose, an attempt has been made to design a questionnaire based on the model of Bolliger and Vasilik (2009) to measure the satisfaction of professors with online teaching. In order to create, compile and standardize such a questionnaire, the literature related to satisfaction with online teaching, which was available in the form of articles and books, was carefully reviewed. Finally, the definitions and concepts of satisfaction with online teaching were designed as 30 questions with 5 options using the "Likert scoring" method in the form of measuring the satisfaction of professors with online teaching. The reliability of the questionnaire was evaluated through Cronbach's alpha and retest and construct validity through confirmatory factor analysis. The formal and content validity of the questions was examined by asking the opinions of 19 expert professors in the field of online teaching, and its reliability was also tested on 50 professors of online courses in the "retest" method and at a time interval of 5 weeks. , 0.72 was calculated. Then the questionnaire was implemented on 350 professors of the virtual courses of Payam-Noor University and by using factor analysis with "rotational" method of "Varimax" type, 3 factors with characteristic value higher than 5 were determined as follows: "Satisfaction" from the organization", "student satisfaction" and "self satisfaction". Therefore, the reliability coefficients were between 0.68 and 0.89 for all subscales and 0.78 for the whole questionnaire by the test-retest method. The internal consistency coefficients for all subscales were between 0.62 and 0.75 and for the whole questionnaire was 0.93. In general, the validity and reliability coefficients obtained for the questionnaire were satisfactory. The designed questionnaire is distinguished from other questionnaires in the field of online teaching satisfaction for two reasons. First, this questionnaire covers areas of satisfaction that are related to organizational, student, and self-satisfaction. Second, each of its questions is derived from a defined index, and this issue makes the professors' "satisfaction with online teaching" based on a theoretical framework. Finally, it can be said that according to the reliability and validity results, this questionnaire is a relatively suitable tool for measuring the threshold of "satisfaction with online teaching" of online course professors at Payam Noor University. Obviously, building a scale to measure an existing structure is extremely difficult and time-consuming if done correctly; For example, studying the history of the formation of well-known tests in the world, which are highly reliable and valid.

Purpose : The present study was carried out aiming to identify the challenges and opportunities of virtual teaching during the Coronavirus pandemic from the perspective of teachers. Methodology : The present study was applied in terms of its purpose and qualitative in terms of its implementation. The statistical population includes middle school and high school teachers in the city of Dehloran during the 2020-2021 school year. The sample size was determined 18 people based on the principle of theoretical saturation and purposive sampling was used. The study was conducted through semi-constructed interviews and data analysis was done based on thematic analysis. The credibility of the findings was assessed using face validity (Five academic experts including two sociology professors, one psychology professor, and two curriculum design professors) and Cohen’s kappa agreement coefficient was used for reliability, for which a value of 0.88 was obtained. Findings : Findings show that 23 open codes and 7 axial codes (a globalized approach, parents’ experiences, the lower psychological and economic cost of virtual teaching, the constant nature of virtual teaching, the adaptability of pillars of the education system, a selective teaching method, and teachers’ social status) were identified as opportunities of virtual teaching. Also, 24 open codes and 8 axial codes (infrastructural factors, economic challenges, ambiguity about roles, lack of technological skills, lost motivation in teachers and students, the risk of teaching, and teachers’ competencies) were identified as challenges of virtual education during the pandemic. Conclusion : Given the uncertainty of when the pandemic will be completely done with, the continuation of virtual teaching is necessary and those in charge of education must seriously pay attention to the present challenges to improve its quality.
