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

The present research was done to conceptualize the open pedagogy in the thought of Michel Foucault and Jacques Derrida and its progression in the distance education system. In terms of the type of research, the present research is theoretical, the statistical population includes all sources and documents related to open pedagogy, the educational perspective of Michel Foucault and Jacques Derrida, and distance education, which contains all electronic and written books, articles, magazines, sites and reliable databases, theses, and doctoral theses. The statistical sample is all available sources and documents related to the subject. The method of data collection is the library and the researchers studied and analyzed all electronic and written books, articles, magazines, sites, and reliable databases, theses, and doctoral theses to the extent of sufficiency. To answer the research question, the collected information was classified, analyzed, and interpreted. Education experts’ opinions have been used to determine validity and reliability. Nine key categories were extracted from the collected information: 1. Aim, 2. Teacher, 3. Student, 4. Teaching method, 5. Content and topic, 6. Planning, 7. School, 8. Evaluation, and 9. Resources. The results of the research reveal that the concept of open pedagogy existed in most of the main subcategories, except for the two categories of planning and resources. Open pedagogy is the most suitable pedagogy for distance education.
