Purpose: The aim of this study was to identify the components of distance education in rural areas in order to provide a model in secondary schools in the country. Methodology: The combined research method was exploratory. In the qualitative part of the study, content analysis with inductive approach was used. Research environment in this section, 84 documents including 67 articles and books, 17 texts of interviews in the field of distance education that were selected as a sample, the components obtained in this research include 7 main components including management and leadership infrastructure, Economic infrastructure, technical infrastructure, educational infrastructure, socio-cultural and value infrastructure, organizational infrastructure and human infrastructure and 25 sub-components. The relative content validity coefficient was used to assess the validity and the Holsti coefficient was used to determine the reliability of the themes. The extracted reliability coefficient was 0.98 which indicated the high reliability of the themes. In the quantitative part, 290 members of the sample were selected by Cochran method and stratified random sampling method. The research tool was a 70-item researcher-made questionnaire. To evaluate the validity of the questionnaire, face, content and structural validity were used, and to assess its reliability, Cronbach's alpha with a value of 0.90 was used. Descriptive statistical methods were used in the analysis of quantitative data including frequency distribution tables and graphs and in the inferential section of confirmatory factor analysis. According to the relative Chi-square fit indices, adaptive fit, adaptive fitting and barbell, the model had a good fit. Findings: The results showed that among the identified components, educational infrastructure was ranked highest and human infrastructure was ranked lowest, respectively. Discussion: E-learning is useful for rural areas in terms of knowledge, better job opportunities, advancement and learning of developing technologies in marketing, and focusing on rural areas helps people's social development and mental ability.

Purpose: The aim of this study was to design a combination learning model in technical and vocational education. Methodology: This study was applied in terms of purpose and exploratory (quantitative and qualitative) in terms of implementation method. The research population was in the qualitative part of documents and resources and specialists in the field of combined learning and in the quantitative part were the principals and students of technical and vocational schools in Zanjan province in the academic year 2018-19. The sample of research was in the qualitative part of documents and resources related to combined learning and 17 experts in the field of learning who were selected according to the principle of theoretical saturation by sampling method of network experts and in the quantitative part were 176 administrators and students who according to Krejcie and Morgan table with Cluster sampling method was selected. Data were collected by filing methods, interviews and a researcher-made questionnaire (39 items) whose face and content validity of the questionnaire was confirmed and its reliability was obtained by Cronbach's alpha method of 0.81. Qualitative data were analyzed by open and axial coding method based on Klein model and quantitative data were analyzed by Delphi methods to determine the validation of the model and t-test. Finding: The results showed that combined learning in technical and vocational education included 43 basic concepts and 9 structural concepts including learning objectives, learning content, learning activities, learning strategies, grouping, learning materials and resources, learning time, learning location and evaluation. The combined learning model of design and its validity by experts with Delphi method was approved in two stages and the number of basic concepts was reduced from 43 to 39. The results of t-test also showed that technical readiness and readiness of human factors combined learning had an effective role in technical and vocational education. Conclusion: According to the results, the designed model of combined learning approved by experts can be used in combined learning environments in technical and professional organizations and can be a criterion for future research in this organization.
