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.

Purpose: The purpose of this study was to investigate the design of a model based on the impact of information technology on the empowerment components of professors with mediating role of social resilience in the Payame Noor University of Mazandaran province. The research method was descriptive-correlational. Method: The statistical population of this research included all professors (scientific and invited) in Payame Noor University of Mazandaran (2539 people). In this study, 280 people were selected as the sample from three branches of Mazandaran Payame Noor University using randomized cluster method. Three standard questionnaires used as the measurement instruments in this research were Ghasemi’s information technology questionnaire, Spreitzer’s empowerment questionnaire, and Connor and Davidson’s resilience questionnaire. In the descriptive statistics part, plotting charts and calculating the statistical indices were used to describe the hypotheses. Structural equation modeling test was used to analyze the data. The data were analyzed using SPSS22 and Amos software. Results: The findings of this research indicated that the design of the model based on information technology influences the empowerment components of professors with mediating role of social resilience in the Payame Noor University of Mazandaran province and all the paths of the effect of the exogenous variables on endogenous variables and endogenous variables on exogenous variables are significant at the level of a = 0.05. Also, all direct and total effects of the endogenous and exogenous variables were significant (p0.05), and all indirect effects of the exogenous and endogenous variables on the endogenous variables were significant. In the final model of information technology and faculty empowerment variables, the highest path coefficient was for the path from information technology to faculty empowerment (0.72) and then from the components of faculty empowerment to resilience (0.71). Conclusion: Information technology and mediating empowerment components have a resilient effect on empowerment components and have shown their mediating role well.

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.
