The present study was to investigate the adaptation of the curriculum components of the Payame-Noor University eLearning system with the constructivist approach and to develop a model in order to promote the quality of the university curriculum. The research design is a mixed model of qualitative and quantitative approaches. The study population consists of experts, professors, and students from e-centers of Payam-Noor University. Three e-centers of Tehran, Isfahan, and Arak were selected and, from these e-centers, 863 individuals using the quota sampling method were drawn. The measure was a researcher-made questionnaire. The methods of One-way ANOVA and One-Sample T-Test using SPSS software (V. 22), and the study model was confirmed using Structural Equation Modeling, AMOS software (V. 22). the results demonstrated that none of the components of the curriculum of the university eLearning system is consistent with the principles of the constructivist approach. By contrast, the analysis of each component between groups revealed the different results. based on experts' opinions goals, teaching-learning strategies, the roles of students and lecture , from the standpoint of professors , teaching-learning strategies and the role of lecturers and from the viewpoint students, goals and teaching-learning strategies of the current curriculum were consistent with the constructivist approach and all study groups agreed on the non-adaptation of the content and evaluation of the university eLearning system with the constructivist approach and The research model fits the data in an acceptable manner and might effectively promote the quality of the curriculum of the university eLearning system.

Due to the changing business environment, organizations have to consider innovation as a necessary prerequisite to increase their efficiency, productivity and sustainability. In this regard, they should pay more attention to increasing job enthusiasm, psychological empowerment, and stimulating innovative work behaviors. Therefore, this research was conducted with the aim of investigating the mediating role of job enthusiasm in the model of innovative work behaviors based on psychological empowerment. In terms of the objective, this research is part of applied research, and in terms of the data collection method, it is part of correlational quantitative research. The statistical population of this research was made up of all the male and female employees of the oil company in the central regions of Iran in 1401. Using simple random sampling, 345 people were selected as the research sample. The data of this research were collected using Spritzer and Mishra's (1995) Standard Questionnaires of Psychological Empowerment, Job Enthusiasm,      Salonava and Shoufeli (2001) and Innovative Work Behavior of Dijang and Denhartog (2010). According to the results of the research, the effect of psychological empowerment on job enthusiasm was 0.380, on innovative work behaviors was 0.297, and the effect of job enthusiasm on work behaviors was 0.352 (p<0.001). In addition, the results showed that psychological empowerment due to job enthusiasm has an effect on innovative work behaviors to the extent of 0.667 (p<0.05). Therefore, all variables have positively and directly influenced each other (p<0.001).

The present study is to investigate the adaptation of the e-learning system curriculum with the principles of constructivist approach from the perspectives of faculty members and undergraduate at PNU. The research method was descriptive-survey. The population consisted of 1987 faculty members and 19882 students of the PNU e-poles in academic years of 2016-2017. Based on the Cochran's sample size formula, 320 faculty members and 375 students were randomly selected using the simple random method. The data were collected using a researcher-developed questionnaire, designed to adapt the curriculum of e-learning system with the constructivist approach in four elements (goal, content, teaching-learning strategies, and evaluation). The face and content validates were measured to find the adaptation level of the e-learning system curriculum with the principles of the constructivist approach. In addition, the reliability of the questionnaire was assessed using the Cronbach's alpha coefficient (α = 0.86). The data were analyzed by a quantitative method using the one sample t-test and the multivariate analysis of variance. Accordting on the one sample t-test results, however, in all four elements related to the curriculum of the e-learning system, the mean of students and faculty members’ responses was less than average and pronounced as insignificant. Thus, the curriculum of the PNU e-learning system was not proposed to be adopted with the constructivist principles. In addition, the results from the multivariate analysis illustrated that there is no significant difference in all four curriculum principles between the viewpoints of the faculty members and the students at PNU.
