Purpose: The main of this research was to calculate the efficiency of 9th grade high school female students as well as educational process development to increase the math literacy. Methodology: This educational process is done by combining realistic mathematics education and the process of solving mathematical problems by quasi-experimental method. The statistical population of the study was 242 ninth grade students in district 19 of Tehran province in the 98-99 academic year; they were divided into two groups of 122 students as experimental group (A, B) and 122 students as control group (C, D). The data analysis method was based on Data Envelopment Analysis (DEA). The output-oriented Charles, Cooper, and Rhodes (CCR) model was used for determining the efficiency of the students. Findings: Each student was considered as a decision-making unit (DMU) in which inputs were mathematical pre-test scores and outputs were the mathematical post-test scores. 91.185% of class A students and 93.6% of class B students from the experimental group were efficient, which has much better offspring than the control group. Conclusion: The results showed that the students involved in problem solving and realistic math instruction were efficient and the Pisa test performed very well. In addition, data envelopment analysis was a suitable method for evaluating and analyzing students' annual performance.

Purpose: Considering the role of leadership in achieving the education missions, present research done with the aim of designing a suitable leadership model to achieve new missions of higher education. Methodology: This study in terms of purpose was applied and in terms of implementation was exploratory combined (qualitative and quantitative). The research population in the qualitative part was the higher education experts and in the quantitative part were the personnel of Islamic Azad University of Tehran province in 2018-19 academic years. The research sample in the qualitative part according to the theoretical saturation principle were estimated 13 people who were selected by purposive sampling method and in the quantitative part according to Cochran’s formula were estimated 385 people who were selected by cluster random sampling method with respect to classes (number of staff in universal branches). To collected data in the qualitative part used from interview and in the quantitative part used from researcher-made questionnaire (51 items) which the its content validity was confirmed by experts and its convergent validity by average variance extracted indicator was confirmed and its reliability was obtained by Cronbach’s alpha method 0.84. To analyze data were used from methods of open, axial and selective coding and exploratory factor analysis in SPSS-22 software. Findings: The findings of the qualitative part showed that suitable leadership had 79 concepts, 63 categories and 7 dimensions and new missions of higher education dad 20 concepts, 15 categories and 3 dimensions. The findings of the quantitative part showed that the suitable leadership model to achieve new missions of higher education had 51 indicators or items and 15 components. Also, a suitable leadership model to achieve new missions of higher education was designed and approved by experts. Conclusion: Based on the findings of the present study, higher education specialists and planners can design and implement programs to realization the new missions of higher education.

Purpose: The aim of this study was to investigate the role of individual and collective components on the formation of social trust in high school students. Methodology: The present study in terms of applied purpose and in terms of performance, it was mixed (qualitative and quantitative). The research population in the qualitative section was experts, experts and specialists in the field of education and training and in the quantitative section were the principals and deputies of the second secondary school in Tehran in the academic year 2019-20, whose number was 380. The research sample in the qualitative section according to the principle of theoretical saturation were 15 people who were selected by purposive sampling method and in the quantitative section according to Cochran’s formula were 190 people who were selected by multi-stage cluster sampling method. To collect data, review of research texts and literature, semi-structured interview and researcher-made questionnaire (110 items) were used. The validity of the interview was confirmed by a review of 10 faculty members and its reliability was calculated by the subject internal agreement coefficient of 0.86. It was obtained from 0.70. Data were analyzed in SPSS and AMOS software by content analysis, factor analysis and structural equation modeling. Findings: Findings showed that in the formation of social trust, two components, individual and collective, played a role. Determination, self-control and collective component had nine dimensions of social commitment, social participation, social support, social respect, and social discipline, loyalty to values, behavioral validity, social development and friendly relations. Conclusion: The results showed that individual and collective components played an effective role in the formation of social trust in high school students

Purpose: The main purpose of this study was to develop a model of factors affecting students' creativity and to evaluate its validity. Methodology: The research design was an exploratory (qualitative-quantitative) mix. In the qualitative part of the target population, all teachers of the sixth grade of elementary school in the 5th district of Tehran and professors of psychology and educational sciences were prestigious universities in the country, which were selected by purposive sampling of 10 teachers and 10 specialists. In a small part of the population considered in this study, all female primary school students in the sixth grade of the 5th district of Tehran in the year 1998-97, 350 of them were selected as a sample and in random clusters. In the qualitative part of the research, a semi-structured interview was used to obtain information and in the quantitative part, a researcher-made questionnaire was used. The validity and reliability of the questionnaire were confirmed. Factors with very minor changes in exploratory and confirmatory factor analyze using LISREL software and SPSS / 26 were accepted.
