This research was descriptive and qualitative method was used to collect information. In this research, the researcher introduces educational systems based on open education, and the search and collection of information was done by studying documents, libraries, and searching for various written and digital sources. It was analyzed by software. The obtained results show that this education started under the name of correspondence education in the first decade of 1700 AD and has passed through five generations until today. In addition to its advantages, open education has many challenges. These challenges were summarized in eight and 80 features.

The purpose of this study was to investigate the effect of philosophic mindedness training on the effectiveness of students’ virtual training components. The present study was a quasi-experimental with a pre-test and post-test design with a control group. The statistical population of this study includes all student’s master’s degree of curriculum in Payame Noor University, south Tehran branch in 1399-1400 academic year. The sample consisted of 32 students who were selected by goal-based random sampling method and randomly assigned into two experimental (n=16) and control (n=16) groups. After conducting pre-test on both groups, the experimental group received Smith's philosophical mentality dimensions (Comprehensiveness, Penetration, Flexibility) (1956) in six sessions of sixty minutes and within six consecutive weeks by e-learning method, but the control group received no intervention. The research tool was a 34-item researcher-made questionnaire. The content validity confirmed by judgment of experts and professors, and its reliability was calculated and at an acceptable level. Data were analyzed using univariate analysis of covariance (Ancova). The results showed that there is a significant difference between the two groups of experimental and control in the effect of philosophic mindedness training on the effectiveness of virtual training. Therefore, it can be concluded that by training and enhancing the dimensions of philosophic mindedness of students of the target community, it can be increased the effectiveness of virtual training courses.

Purpose: Media literacy plays an important role in teaching and learning curriculum. Therefore, the purpose of the present research was to design and validate the media literacy education model in secondary school. Methodology: This was an applied study in terms of purpose and qualitative in terms of implementation method. The study population for designing the media literacy education model was the specialized council of the thinking and media literacy book department of the country (n=18 people) who were selected by census sampling method. Also, the study population for the validation of the media literacy education model was professors and researchers in the field of communication, Education Department experts and experienced teachers in the field of media literacy, 20 of whom were selected as a sample using the purposeful sampling method. The data collection tool was in-depth interviews in the model design section and calculation the agreement rate in the model validation section. Data analysis was carried out by coding method in MAXQDA ver.10. Findings: The results showed that the model of media literacy education in secondary school consisted of 40 components in 7 categories of media message creation techniques, media unknowns, audience studies, media and lifestyle, media consumption regime, harm of media literacy education and opportunity of media literacy. Also, the model of media literacy education in secondary school had an acceptable validity after calculating content validity ratio (CVR) (0.88) and content validity index (CVI) (0.91) based on the opinion of professors and researchers in the field of communication, Education Department experts and experienced teachers in the field of media literacy. Conclusion: Based on the results of the current research, it seems necessary to plan for the inclusion of media literacy education in secondary school curriculum through the identified components and categories.

Purpose: Epistemology as one of the philosophical foundations in the field of education can play an important role in blended learning, ie using more than one method, strategy and technique for learning. Therefore, the present study was conducted with the aim of designing and validation the epistemological model in blended learning Methodology: The present study was applied from type of qualitative-quantitative. The population of the qualitative section was the documents related to epistemology and blended learning in the years 1990 to 2020 which 80 books, 60 dissertations and 60 articles were selected by purposive sampling method and in addition, included experts in the field of philosophy of education and distance learning which based on the principle of theoretical saturation number of 10 people of them were selected by purposive sampling method. The population of the quantitative section were faculty members and doctoral students of the department of philosophy of education and distance learning of Payame Noor University in 2020-2021 years which based on Krejcie and Morgan's table number of 200 people of them were selected by stratified random sampling method with using the teacher and student ratio. The tool of the qualitative section was the recording of books, dissertations and articles and interviews with experts, and the tool of the quantitative section was a researcher-made questionnaire whose psychometric indicators were confirmed. Data were analyzed by coding method in MAXQDA software and exploratory factor analysis and one-sample t-test in SPSS software. Findings: Findings showed that the epistemological model in blended learning had 60 subcategories in 9 categories including purpose, evaluation, educational correction, content, teaching method, teacher, learner, media and cognitive presence that its model was drawn. Also, validation of model indicated that the factor load of all 6 questions related to validation of model was higher than 0.30, their validity was higher than 0.50 and their reliability was higher than 0.70. In addition, the mean of all 6 questions was higher than the hypothetical mean of the population (P<0.001). Conclusion: The findings showed that the designed model for epistemology in blended learning had good validity. Therefore, curriculum specialists and planners can use this model along with other models to improve blended learning
