According to the purpose of the research, this article analyzes educational systems based on open education: challenges and opportunities in the field of learning. This method of teaching and learning is one of the new educational methods used in open university. Due to the use of electronic tools, higher education is moving away from its traditional form and moving towards distance learning and education. 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. Undoubtedly, in order to achieve an open and favorable higher education system, one should try to examine the challenges in this field and then by removing the limitations and turning them into opportunities, he took a big step in the direction of the higher development of open education.

Purpose: The purpose of the present research is to review the effectiveness of philosophy education program for children on critical thinking and its components in elementary fourth-grader girl students. Material and method: This was a semi-experimental study with designing pretest and posttest and the control group with following-up phase. Findings: This statistical population consists of elementary fourth-grader girl students in Arak, district 2. The sample of this research consists of 50 students that were selected by convenience sampling method and divided to two control and test groups. Shabani (1999) critical thinking questionnaire was used for data collection. Discussion: The results of covariance analysis showed that execution of the philosophy education program for children improves critical thinking, recognition ability, analogizing, and judgments in children (P<0.05). Furthermore, the effectiveness of philosophy education program for children was durable in fallowing-up test.

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.

Learning of students. This study, in terms of purpose, applied, and in the manner and method of implementation, is an integral part of empirical studies. In this research, a four-group Solomon design with pre-test and post-test, and control group were used. The statistical population consisted of all undergraduate students at Kermanshah Payam Noor University, who had specialized  language lessons during the semester. Among them, 60 people were selected as the statistical sample using available sampling. To test the students' learning, a researcher-made test was used. The validity of the test using the Kooder Richardson method was 82. announced. SPSS software was used to perform statistical calculations, and multivariate analysis of variance analysis was used to investigate the hypotheses of the research. The results of the data analysis showed that there is a significant difference between the mean scores of the experimental and control groups in the visual, written, audio, and oral components, but the effect of the pre-test, as well as the interaction of pretest and group is not meaningful. The results also showed that the participation of learners in training exercises, while paved the way for activating knowledge of learners' resources, helps them to associate past and future. These findings ultimately confirm the impact of multimedia education on the level of learning the student's English language vocabulary, and can be used in conjunction with other intervening methods. 

Textbooks are the most important forms of media in open and distance universities. As a result, they should have features that enable the distance learners to attain in-depth learning without the presence of an instructor. This study aims to design a comprehensive model for open and distance university textbooks through analyzing the textbook concept using the hybrid model. In the initial stage, a review of literature up to 2011 was done (119 cases) using several databases.  Then, a field study was carried out by assessing 2 textbooks from open universities of England. Finally, data collected from the two previous stages were analyzed and evaluated, using Strauss and Corbin's method, and a proper model was proposed for open and distance university textbooks.

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.
