The purpose of this study is to provide a conceptual framework for the e-learning system of higher education institutions in the Iran, based on the views of experts related to the field of e-learning at the level of higher education institutions and prioritizing factors over each other. The present study is applied in terms of purpose; It is descriptive-exploratory in terms of how data is collected and qualitative in terms of the nature of the data. Accordingly, in order to collect qualitative data, after reviewing the literature related to the research topic, a framework was developed to ask questions of interviews with experts. Then, using purposive sampling method (snowball), the opinions of 15 experts up to the theoretical saturation stage were used. The interviews were coded using Clark and Brown six-step inductive theme analysis. Accordingly, the identified speech evidence from the interview text was labeled in the form of 53 initial codes. Then, the initial codes were drawn in the form of 12 sub-themes and then, three main themes including specialized requirements of e-education system, general requirements of e-education system, results and consequences of e-education system, classification and conceptual conceptual framework of e-education system of higher education institutions. Then, in order to validate the results of the interviews and confirm the components of the research conceptual framework, the fuzzy Delphi questionnaire and method were used and in order to prioritize the components of the research conceptual framework, the fuzzy hierarchy questionnaire and process (FAHP) were used. Based on the results of the research in the Delphi section, all 12 sub-themes or questions of the Delphi questionnaire were approved by the research experts. The results of fuzzy hierarchical analysis also showed that the technical requirements of e-learning have the highest priority among the specialized requirements, followed by the quality requirements of the education system, support requirements, requirements related to professors, requirements for educational quality and related requirements. With students, they are in the next ranks. Also, achieving effectiveness is the highest priority among the general requirements of the e-learning system, followed by satisfaction, optimal use and utilization, in the next ranks. In addition, saving time and money is the highest priority. Among the factors and then the development of learning and integration of education, are in the next ranks.

Purpose: This study is investigating the position of components of sustainable development in experimental science course of Elementary Schools of Iran and presenting an optimum framework and its validation. Methodology: The statistical population is a group of monitoring experts on the components of sustainable development as well as a set of experimental science textbooks in sixth grade of elementary schools of Iran during the academic year of 2016-2017. The sample size according to Morgan's sampling table in expert group was 80 and 12 volumes of textbooks sets, including teacher guides. The sample size in the group of experts was 80 according to Morgan's sampling table and 12 volumes in the collection of textbooks, including teacher guides. Findings: The results of the research indicate that the amount of emphasis on the component of the consumption pattern was 5.24% in objectives, 5.86% in educational content, 6.05% in teaching method and 6.69% in assessment. In the waste disposal component, the emphasis is: 4.1% in objectives, 2.15 % in educational content, 2.78% in teaching method and 5.1% in assessment. In the component of animal conservation, the emphasis is: 15.68 % in objectives, 18.03 % in educational content, 9.4 % in teaching method and 9.39 % in assessment In the energy component, the emphasis is: 12.29 % in objectives, 14.59 % in educational content, 14.66 % in teaching method and 13.25 % in assessment. Discussion: In sum, the amount of emphasis of the curriculum of the experimental science course of Elementary Schools was in middle level compared to the six components of sustainable development, and needs to be reviewed.
