The statistical population of the study in the qualitative part was all experts and experts in educational management and planning with 10 people and in the quantitative part included all teachers and principals working in primary schools in Shiraz. The data collection tool was a researcher-made questionnaire. To collect the data in the second stage, a closed questionnaire with a Likert scale of five was used. Findings: The results showed that the results of semi-structured interviews during several stages of coding and also inspired by the research background, led to the identification of the initial code. In the second step, the identified concepts were categorized into the following categories. These fourteen categories are; 1. Management of learning and teaching 2. Creating a conducive learning environment 3. Assessment and curriculum 4. Outline vision 5. Continuous school improvement 6. Effective communication and collaboration 7. Relationship with society and stakeholders 8. Operations management 9. Resource management 10. Guidance and leadership of individuals and teams 11. Professional ethics 12. Islamic ethical principles and norms 13. Develop your career 14.

Purpose: The purpose of this study is to investigate the effect of both work to family enrichment and family to work enrichment on family satisfaction and work satisfaction. The moderating role of positive and negative affectivity is also examined in this regard. Methodology : This Study is an empirical survey research with the statistical population of faculty members of Iran’s universities. The research questionnaires were distributed among professors of five premier universities of Tehran. 200 people were used by simple random sampling. Carlson et al. (2000), Carlson, Kacmar, and Williams (2000), Brayfield and Crockett (1955), Schumm, McCollum, Bugaighis, Jurich, and Bollman (1986) and Agho et al. (1992) questionnaires were used and research hypotheses were tested through structural equation modeling by PLS software. Findings : The results showed that according to path coefficient, work family enrichment has a positive and significant effect on faculty members’ job satisfaction (0.7562) and family satisfaction (0.7362) both T-statistics are upper than 1.96. Positive affectivity enhances these relationships as a moderating variable (0.6423). However, negative affectivity had no significant effect on the relationship between work family enrichment and family and job satisfaction (both T-statistics are lower than 1.96). Conclusion : positive aspects of work family interface, in other words, work family enrichment in comparison with work family conflict variable should be considered as an important variable in psychology of family and organization. The issue of work family enrichment in the scientific jobs of faculty members of universities which have distinctive job qualifications compared with other jobs could have a significant effect in job and family satisfaction

Purpose: The present study aims at analyzing the content of work and technology curriculum in the junior high school. Methodology: A qualitative and applied research method was used, which was performed based on the content analysis. The statistical population consisted of work and technology curricula of the junior high school in the academic year 2019-2020, which were examined without sampling. The data collection tool was a triple list designed based on the goals of economic-professional education set out in the fundamental reform document of education. The collected data were analyzed using Shannon entropy software. Findings: In this software, the frequency of each data unit was identified, its indices of descriptive statistics were extracted and the importance coefficients of each of them were reported. The data in this study was in the form of themes, photos and learning activities. Therefore, data analysis was performed by using descriptive statistics indicators and their quantitative analysis. The results showed that the rate of emphasis on economic-professional education in work and technology curricula in each of its eight goals was as follows: understanding professional skills 0.99, professional ethics 0.066, entrepreneurship 0.053, avoiding unemployment 0.052, observance of productivity 0.040, commitment to ethics and values 0.039, wealth development 0.038, business laws 0.032, economic justice 0. Conclusion: The content analysis of the work and technology curricula of the first year of high school showed that the understanding of professional skills in the seventh grade was 46.6%, in the eighth grade was 75.4% and in the ninth grade was 61.5%
