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: This study uses TAM theory to better understand variables that are indicative of MOOCs’ courses’ completion rates; furthermore, this paper scrutinizes the quantitative relationship between MOOC platform usage and learning satisfaction. Methodology: This was an applied research in a virtual community called Coursera where people all over the world participate. The research design was quantitative and the questionnaire link was posted on the Coursera, with convenience sampling. Data collection process started from November 12, 2020 until February 23, 2021, and 234 users of the selected MOOC platform (Coursera) participated to evaluate the proposed model. A multivariable systematic technique (PLS) was applied to analyze the model. To conduct the reliability test, individual item loadings and internal consistency were consulted. Convergent validity of the model was measured via the Structural Equation Model (SEM). The examination of the SEM was incorporated an evaluation of the path coefficients and R2 values. Findings: The loadings of all measurement items are larger than 0.792, indicating sound internal reliability of the dataset. Moreover, the Cronbach's alpha values are all > 0.7 which proves the internal consistency of the research model. In this research, the range of CR is 0.838 to 0.947 and the range of AVEs 0.634–0.857, both exceeding the threshold values for desirable convergent validity. To obtain discriminant validity, the square root of AVE should be larger than the correlation among the constructs. The value of each AVE’s square root is greater than the off-diagonal components. The model explains 21.1% of the variance in perceived usefulness, 20.9% in perceived ease of use, 26.9% in attitude to use, 20.0% in MOOC platform actual usage and 24.2% of the variance in learning satisfaction. The path coefficient from quantity and quality of knowledge (β=0.261, p<0.01) and perceived feedback (β=0.215, p<0.01) to PU are positive. The results show that perceived feedback (β=0.275, p<0.01), perceived complexity (β=-0.367, p<0.01) significantly and meaningfully affect PEOU. The PU showed a positive and strong effect on attitude to use (β=0.271, p<0.01), MOOC platform actual usage (β=0.360, p<0.01), and learning satisfaction (β=0.277, p<0.01). Conclusion: The results indicated that the quantity and quality of the knowledge and perceived feedback have a positive and significant impact on the perceived usefulness of MOOCs. The perceived complexity as a negative construct was found to be an important indicator of MOOC platforms usage.

Purpose: The objective of the present study was to present a model for training organizational citizenship behaviors in the Education Organization based on grounded theory. Methodology: The present study was applied in terms of objective. For a rich description of the experiences, attitudes and perception of the interviewees towards training organizational citizenship behaviors, the qualitative research method was used and in particular grounded theory (systematic approach) was used to achieve a paradigm model. The population of this study included professors, university experts and directors of education in Kermanshah Province. Sampling in the present study was purposeful, in which 14 people were selected from the mentioned ones. In this study, interviews have been used to collect their views related to the training of organizational citizenship behavior in the Education Organization. Content validity was used to evaluate the validity of the construct and Cronbach’s alpha coefficient was used to evaluate the reliability. The research tool in this section was a questionnaire and for data analysis, SMART PLS3 and SPSS23 software were used. Findings: The results showed that causal conditions (employee empowerment; decentralization; and employee awareness of organizational citizenship behavior); axial phenomena (chivalry and forgiveness, conscientiousness; organizational spirituality; respect and esteem; and civic virtue); strategic factors (organizational contexts, fair and rapid feedback; observance of justice in the organization; policy making; and increasing employee motivation); confounding variables (personality traits; and cultural, social, political and economic conditions); background conditions (organizational culture, transformational leadership, and organizational support) and consequences (effectiveness and improvement of organizational performance; employee satisfaction; organizational commitment, cooperation and participation) affect the training of organizational citizenship behavior in the Education Organization. Conclusion: The study results showed the effect of each of the different categories on the training of organizational citizenship behavior. So, to succeed in this regard, special attention should be paid to these categories. Therefore, in order to achieve higher effectiveness and proper hiring of employees with extra-role behaviors, the Education Organization should consider and implement the necessary program and preparation for training organizational citizenship behaviors.

Purpose: Since the prevalence of Covid-19 increased the use of e-learning and its dual importance in teaching methods, this study aimed to compare the effect of two teaching methods of brainstorming and group discussion by e-learning on learning level and interest in teamwork in social studies course. Methodology: This was an applied study in terms of purpose and semi-experimental with pre-test and post-test design in terms of implementation method. The study population was the third-grade elementary school students in district 20 of Tehran in the academic year of 2020-2021. The sample size was 60 students in two classes with 30 ones who were selected by available sampling method. One of the classes was considered as a teaching group with brainstorming method in a random way and the other class was considered as a teaching group with group discussion method. The teacher-made test of learning level in the social studies course and the teamwork interest questionnaire (Evans & Jarvis, 1986) were used to collect the data. Findings: The results of paired t-test showed that both methods of teaching brainstorming and group discussion by e-learning enhanced the level of learning and interest in teamwork in social studies course (P <0.001). The results of univariate analysis of covariance showed that the group discussion teaching method in comparison with the brainstorming teaching method enhanced the learning level and interest in teamwork in the social studies course (P <0.001). Conclusion: The results showed the effectiveness of both methods and the greater impact of group discussion teaching method compared to the brainstorming teaching method in both variables of learning level and interest in teamwork. Therefore, the use of group discussion teaching method should be prioritized to improve academic performance in social studies course.
