Purpose: The aim of this study was to design an effective school model based on the model of learning organization in primary school in Tehran. Methodology: The research method was a combined research method (qualitative and quantitative) by grounded theory method and structural equation model by quantitative method. The research population was in the qualitative section of university professors specializing in primary education and in the quantitative section were experts in the field of education in Tehran in 2009-2010. Twelve people were selected as a sample in the qualitative section by purposeful method from university professors and 196 experts and specialists in education in Tehran were selected by multi-stage cluster sampling. The research tool was a semi-structured interview in the qualitative part of the interview and a researcher-made questionnaire in the quantitative part of the effectiveness of the learning schools. The data were analyzed in the qualitative part by the grounded method of exploratory theory and in the quantitative part by the structural equation model test and factor analysis. Findings: The results showed that the model of confirmatory factor analysis of the first stage and the relevant factor were: empowerment of human resources (with a factor of 0.926), establishment of teaching and learning system (with a factor of 0.910), extracurricular activities (with a factor of 0.914), Competencies of managers (with a factor of 0.910), competencies of teachers (with a factor of 0.978), educational policies (with a factor of 0.934), technological facilities (with a factor of 0.905). Conclusion: Based on the research findings, it can be said that the priority factors of effective schools are: First priority: Empowerment of human resources, Second priority: Establishment of teaching and learning system, Third priority: Extracurricular activities, Fourth priority: Competencies of principals, Fifth priority: Teachers' competencies, Sixth priority: Educational policies, Seventh priority: Technological facilities.

Purpose: The aim of this study was to investigate media literacy on creativity skills, critical thinking and problem-solving skills of sixth-grade students. Methodology: The statistical population of the present study was all sixth-grade students of non-profit schools in Tehran in the academic year of 2018-2019 whom 206 girls (from the population of 5056 people) and 163 boys (from the population of 4002 people) were selected as the cluster sampling method. The Simone Questionnaire (2017) was used to measure media literacy, the Harris Questionnaire (2016) was used to creativity, the Sarigoz Questionnaire (2012) was used to measure critical thinking and the Sirait Questionnaire (2017) was used to measure problem-solving skills. For data analysis, data analysis method of structural equation technique was used and using LISREL and SPSS software at a significance level of 0.05. Findings: The results showed that media literacy affected the development of creativity, critical thinking and problem solving skills and these effects were not significantly different in the two groups of girls and boys. Also, the mediating role of critical thinking in the effect of media literacy on creativity and the mediating role of creativity in the effect of media literacy on problem solving skills in boys was stronger than in girls (P <0.001). Conclusion: Based on the research findings, it can be acknowledged that media literacy of students can improve problem-solving skills, creativity and critical thinking.

Purpose: The general aim of this study was to present a knowledge commercialization model based on teaching-learning in Mazandaran Islamic Azad universities. Methodology: The present study was applied in terms of purpose and descriptive-survey type in terms of method. The statistical population of this study included all faculty members of Mazandaran Islamic Azad Universities, which comprised 1537 individual. Using stratified random sampling, 308 individuals were selected as sample. To collect the data, a researcher-made knowledge commercialization questionnaire with 84 items and a researcher-made learning-learning questionnaire with 30 items were used. The face and content validity of the tools were confirmed by the experts and their reliability was calculated using the Cronbach's alpha coefficient for the knowledge commercialization questionnaire (0.89) and the teaching / learning questionnaire (0.85). Structural equations were used to analyze the data. Findings: The results showed that learning-learning has a positive and significant effect on knowledge commercialization, and the knowledge commercialization from learning-learning receives a direct and significant effect with a coefficient of 0.785. The fit of the proposed model was also suitable. Conclusion: knowledge commercialization is a process of transferring and transforming knowledge generated in research centers into a variety of business activities.
