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

In regards to the need to use technology in the domain of learning and the important role of principals of educational organizations in implementing the blended learning, this research was carried out with the aim of identifying the parameters of psychological and center skills of principals in implementing the blended learning from quantum paradigm perspectives. The research method was qualitative and of meta-synthesis. Data collection was carried out through reviewing scientific documents and resources relevant to the subject of research in recent 31 years (1990-2021). Therefore; the related key words were searched in the reliable internal and foreign websites and finally, 42 resources were selected for final review. The review was done through studying the resources of the principals’ psychological skills in three dimensions and eleven parameters and center skill in one dimension and three parameters. The results obtained from this research showed that with regards to the identified dimensions and parameters, principals can play roles in implementing the blended learning in educational organizations, from the psychological skills, in quantum seeing dimension, by planning informed and effective leadership and confronting challenges and eliminating obstacles, in quantum thinking dimension via creative thinking, change and comprehensive thinking, in quantum feeling via accountability, supporting individuals’ rights and security, respecting values , caring about needs and talents and utilizing the process of information and from center skills perspectives and quantum being dimension, via establishing an appropriate learning atmosphere, establishing effective communication and creating a resilient and network-centric structure.

The purpose of this study was to determine the effectiveness of web-based distance learning model in the context of a constructivist learning approach on learning performance, satisfaction and attitude of Payame Noor Sardasht students. The research method was quasi-experimental with pretest-posttest design. The statistical population of the study included all students of Payame Noor University of Sardasht who selected 45 people as the research sample, using Morgan table and cluster sampling method. Of these,15 students were assigned to conventional distance education group, 15 to the distance education group based on reproductive learning, and 15 to the project-based group. Data collection tools included a teacher-made test to measure learning performance as well as a researcher-made satisfaction and attitude questionnaire that the content validity of the teacher-made test was reviewed and approved by professors. And its reliability through splitting method was 82% in pre-test and 85% in post-test using Spearman-Brown formula. The content validity of the satisfaction questionnaire and the attitude questionnaire were reviewed and approved by experts and the reliability of the satisfaction questionnaire was 84% and the attitude questionnaire was 80% using Cronbach’s alpha. Data analysis was performed using inferential statistics and one-way analysis of variance. Emphasizing the research findings, it can be claimed that both web-based distance learning models have a positive effect on students learning, satisfaction and attitude. Based on these findings, it can be concluded that these two educational models (project-based learning and reproductive learning) have a great impact on increasing students’ learning performance, satisfaction and attitude.

Purpose: The objective of the present study was to validate the evaluation model of the quality of combined education in higher education based on the CIPP evaluation approach. Methodology: The present study was applied in terms of objective, and cross-sectional in terms of method and data collection. The statistical population included students of the Islamic Azad University of Tehran in 2020 and 140 students participated in this study by power analysis sampling method. A researcher-made questionnaire on a 5-point Likert scale including 9 main categories, 20 sub-categories and 83 items was used for data collection. Convergent validity, divergent validity and Heterotrait-Monotrait Ratio (HTMT) were used to validate the questionnaire and a value greater than 0.7 was obtained from all categories. The reliability of the questionnaire was investigated using Cronbach's alpha, composite reliability and Rho coefficient and calculated greater than 0.7 in all categories. Also, the total Cronbach's alpha of the questionnaire was 0.891. In order to investigate the conceptual model of the research, the partial least squares and Smart PLS software version 2 have been used. Findings: The results showed that the use of appropriate evaluation methods leads to students' increasing knowledge and skills. Finally, this growth will lead to satisfaction with the quality of education, practicality and field of study. Conclusion: According to the study results, it was found that the appropriate selection of managers by increasing the capability and utility of their role will pave the way for appropriate methods of evaluation.
