Purpose: Considering the role of teachers' motivation in improving the teaching, educating and learning processes, the present study was conducted with the aim of providing a suitable model to promoting teachers' motivation for the education process. Methodology: The present study in terms of purpose was applied and in terms of implementation method was mixed (qualitative and quantitative). The research population in the qualitative part was the academic experts of Tehran city in 2020 year, which number of 15 people of them were selected as a sample according to the principle of theoretical saturation and by purposive sampling method. The research population in the quantitative part was the high school teachers of Tehran city in 2020 year, which number of 316 people of them were selected as a sample according to the Cochran's formula and by simple random sampling method. The research tool in the qualitative part was semi-structured interview and in the quantitative part was researcher-made questionnaire, which the validity and reliability of them were confirmed. The data in the qualitative part were analyzed by coding method based on grounded theory in MAXQDA software and data in the quantitative part were analyzed by exploratory factor analysis and structural equation modeling in SPSS and LISREL software. Findings: The results of the qualitative part showed that the central category included promoting teachers' motivation for the education process, causal factors included work environment, cultural and social context, teaching level, individual characteristics and demographic factors, intervention factors included psychological-attitudinal factors, individual-motivational factors, facility-welfare factors, managerial and structural factors and negation of work, contextual factors included financial rewards, school physical facilities and job enrichment and job development, strategies included planning to improve quality and academic level, behavior, attitude and policy educational of managers, teacher empowerment and encouragement active teacher and outcomes included trustworthy, academic competence, good social relations and understanding of circumstances and duties. Also, the results of the quantitative part showed that the factor load of all components was appropriate and work environment, cultural and social context, teaching level, individual characteristics and demographic factors on causal factors, psychological-attitudinal factors, individual-motivational factors, facility-welfare factors, managerial and structural factors and negation of work on intervention factors, financial rewards, school physical facilities and job enrichment and job development on contextual factors, planning to improve quality and academic level, behavior, attitude and policy educational of managers, teacher empowerment and encouragement active teacher and on strategies and trustworthy, academic competence, good social relations and understanding of circumstances and duties on outcomes had a significant effect on outcomes (P<0.05). Conclusion: According to the results of the present study, to promoting teachers' motivation for the education process can be action through the identified components in the present study.

Purpose: Epistemology as one of the philosophical foundations in the field of education can play an important role in blended learning, ie using more than one method, strategy and technique for learning. Therefore, the present study was conducted with the aim of designing and validation the epistemological model in blended learning Methodology: The present study was applied from type of qualitative-quantitative. The population of the qualitative section was the documents related to epistemology and blended learning in the years 1990 to 2020 which 80 books, 60 dissertations and 60 articles were selected by purposive sampling method and in addition, included experts in the field of philosophy of education and distance learning which based on the principle of theoretical saturation number of 10 people of them were selected by purposive sampling method. The population of the quantitative section were faculty members and doctoral students of the department of philosophy of education and distance learning of Payame Noor University in 2020-2021 years which based on Krejcie and Morgan's table number of 200 people of them were selected by stratified random sampling method with using the teacher and student ratio. The tool of the qualitative section was the recording of books, dissertations and articles and interviews with experts, and the tool of the quantitative section was a researcher-made questionnaire whose psychometric indicators were confirmed. Data were analyzed by coding method in MAXQDA software and exploratory factor analysis and one-sample t-test in SPSS software. Findings: Findings showed that the epistemological model in blended learning had 60 subcategories in 9 categories including purpose, evaluation, educational correction, content, teaching method, teacher, learner, media and cognitive presence that its model was drawn. Also, validation of model indicated that the factor load of all 6 questions related to validation of model was higher than 0.30, their validity was higher than 0.50 and their reliability was higher than 0.70. In addition, the mean of all 6 questions was higher than the hypothetical mean of the population (P<0.001). Conclusion: The findings showed that the designed model for epistemology in blended learning had good validity. Therefore, curriculum specialists and planners can use this model along with other models to improve blended learning
