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

Purpose: Academic buoyancy is one of the effective variables in the academic field and learning environment of students. Therefore, the objective of this research was to design the academic buoyancy model based on life expectancy with the mediation of happiness in female high school students in Hamedan city. Methodology: The methodology of this research was correlational and SEM. The statistical population included all female students of the second secondary school in Hamedan city, and the statistical sample was selected based on the number of items used in the questionnaires as 370 people with the multi-stage cluster sampling method. Academic buoyancy (Hosseinchari and Dehghanizadeh, 2013), life expectancy (Hallajian, 2019), and Oxford happiness (Argyl et al., 1989) scales were used to collect data. For data analysis, a structural equation test was used in the PLS-3 software environment. Findings: The results showed that life expectancy has a direct and positive effect on academic buoyancy (β = 0.36, p <0.01) and happiness (β = 0.46, p < 0.01). Happiness also has a direct and significant effect on academic buoyancy (β = 0.34, p<0.01). Also, happiness has a significant mediating role in the relationship between life expectancy and academic buoyancy (β = 0.16, p<0.01). Conclusion: since life expectancy creates a more positive atmosphere, it can be effective in increasing the feeling of happiness, and happiness creates buoyancy in the academic environment, followed by an increase in academic buoyancy.

Purpose: the aim of the present study was to investigate the dimensions and quality of teaching-learning interactions by elementary teachers during the Covid-19 pandemic. Methodology: this was a qualitative study carried out using a phenomenological approach. The study population included all elementary school teachers in Abhar City (Iran). From this population, 12 individuals were selected as participants in the study using purposive sampling (chain sampling) who were engaged in online teaching from the onset of the Covid-19 pandemic. Data collection instrument included semi-structured or in-depth interviews performed in the Google meet interactive platform. The interviews continued until reaching data saturation. Data analysis was also carried out using thematic analysis and theme network formation. Validity was also assessed using peer review and member checking and reliability was assessed by text coding of three interviews by anonymous people outside the research. Findings: the results reflect the dimensions and quality of teaching/learning interactions by elementary teachers during the Covid-19 pandemic in the form of 226 basic themes, 21 organizing themes and 4 global themes. Conclusion: the results showed that elementary teachers had relatively acceptable interactions with themselves, students and parents during this process. However, there were no acceptable interactions between teachers and their colleagues.
