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.

This paper focuses on the role of influencers as an element of modern governance. As the fields of media, entertainment industry, and politics become increasingly interconnected, the phenomenon of influencer potentially affects many aspects of political life, such as campaigning and voting, policymaking, and international affairs. Using the network analysis method and applying a triple typification of influencers consists of media influencers, influencer politicians in power, and influencer opposition politicians out of power, and selecting 245 nodes on Instagram accounts, the article focuses on how do influencers interact within communication networks? Based on the triple typification, the article tries to find the pattern of networked political communications between influencers in the social network. The results prove that all three types of influencers are more interested in intra-group communication. However, both influencer politicians in power and influencer opposition politicians out of power have relatively similar tendencies to associate with media influencers.

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.
