- چکیده انگلیسی: Learning of students. This study, in terms of purpose, applied, and in the manner and method of implementation, is an integral part of empirical studies. In this research, a four-group Solomon design with pre-test and post-test, and control group were used. The statistical population consisted of all undergraduate students at Kermanshah Payam Noor University, who had specialized language lessons during the semester. Among them, 60 people were selected as the statistical sample using available sampling. To test the students' learning, a researcher-made test was used. The validity of the test using the Kooder Richardson method was 82. announced. SPSS software was used to perform statistical calculations, and multivariate analysis of variance analysis was used to investigate the hypotheses of the research. The results of the data analysis showed that there is a significant difference between the mean scores of the experimental and control groups in the visual, written, audio, and oral components, but the effect of the pre-test, as well as the interaction of pretest and group is not meaningful. The results also showed that the participation of learners in training exercises, while paved the way for activating knowledge of learners' resources, helps them to associate past and future. These findings ultimately confirm the impact of multimedia education on the level of learning the student's English language vocabulary, and can be used in conjunction with other intervening methods.

- چکیده انگلیسی: Background: Teaching and learning are undergoing a dramatic transformation thanks to the technological advances in areas like Augmented Reality (AR). The main purpose of this study was to investigate the factors affecting perceived enjoyment of learning in AR. Methods: This was an applied research in terms of purpose and a descriptive and correlative study in terms of methodology. The statistical population included all undergraduate students at Payam-e Noor University in western areas of Iran during 2019- 2020 academic year (n=24000). A sample of 600 students were selected through randomized multistage cluster sampling based on Cochran’s formula. The participants used an AR application, and then completed an integrated questionnaire, which was a combination of 5 questionnaires (flow, perceived enjoyment, need for cognition, cognitive absorption and self-efficacy). A total of 556 questionnaires were returned. The data were analyzed through path analysis using Amos 22, Lisrel 8.50 and Spss 22. Results: Among the direct effects, self-efficacy had the highest effect on perceived enjoyment (0.28) and need for cognition had the lowest effect on self-efficacy (0.16). On the other hand, cognitive absorption had the highest indirect effect on perceived enjoyment (0.13) and the lowest indirect effects were those of the need for cognition on flow (0.04) and self-efficacy on flow (0.04). The highest total effect was related to the effect of self-efficacy on perceived enjoyment (0.28) and the lowest one was related to the effect of selfefficacy on flow (0.04). Conclusion: The results obtained for the fit indices of the proposed model showed that it had a good fit with the data collected from the respondents (X2 =22.14, P=0.179, CFI=0.99, GFI=0.99, AGFI=0.98 & RMSEA=0.023). Accordingly, this model can provide educators and education leaders with critical information for improving learning outcomes.

- کلمات کلیدی: feedback,Interaction,satisfaction,Effective Distance Education,Flexibility
- چکیده:
- چکیده انگلیسی: Background: Satisfaction is one of the most common indicators of effective learning and many factors, such as interaction, flexibility, and feedback, are involved in the development of satisfaction. Thus, goals of this research was to determine electronic education student’s perception towards effective distance education components and contribution of these components in explaining satisfaction of distance education. Methods: The current research used a survey method. The statistical population consisted of all electronic education graduate students (3915) of universities of Tehran, who took part in distance education in the academic year of 2014 to 2015. Overall, 390 students were selected by the random classified sampling method. For gathering data, 2 instruments were used. One for measuring effective distance education components and another for measuring satisfaction of electronic education. The first scale included 24 items with 3 dimensions, including interaction, flexibility and feedback, and the other scale included 20 items with one dimension, being satisfaction. Data were analyzed through the SPSS software, version 21, and statistical methods were used, such as variance analysis, one sample t - test, and multivariate regression analysis. Validity and reliability of both scales were confirmed through content, convergent validity, and reliability (Cronbach's alpha coefficient of 0.77 for effective distance education scale and Cronbach's alpha coefficient of 0.85 for electronic education satisfaction scale). Results: The mean satisfaction of electronic education of female students (M = 14.44, p ≤ 0/001) was significantly higher than that of male students (M = 11.84 p ≤ 0/001) in all academic groups, including humanities, technical, and basic sciences. Also, data analyses showed that 46% of satisfaction variance could be explained by combination of interaction, flexibility, feedback, gender, and academic groups. Among them, flexibility contribution (Beta = 0.590, P ≤ 0/001) was more than interaction (B = 0.547, P ≤ 0.001) and feedback (B = 0.369, P ≤ 0.001). Conclusions: The research statistical model suggested that interaction, flexibility, feedback, and gender are positive explanations of satisfaction. Also, the research goal was approved, which means that designing effective distance education by proposed agents could lead to greater satisfaction of electronic education students.

- چکیده:
- چکیده انگلیسی: The learning system provided by the municipalities is one of the most important motivating factors make citizens to participate in urban management plans such as source separation of wastes. In the past years, Tehran municipality has been focusing on providing different training in waste management and specifically source separation, which has not been able to attract public participation. The aim of this paper is to study the failure causes of learning systems and to address the shortcomings in the form of distance learning to provide the most effective learning method. In this regard, the Khan conceptual model has been used in the fuzzy analytic hierarchy process. Finally, the results of the 100 paired comparison questionnaires in this study, which were obtained using Khan's conceptual model and fuzzy theory, introduced mobile applications as the best method of distance learning. The strengths and reasons for its selection, which were obtained from interviews conducted by residents of district 16 of Tehran municipality, are described. To compare between different types of distance learning methods, 8 criteria were used in 25 proposed subcategories categorized by Khan's conceptual model that could integrate the concepts and basis of a standardized and successful distance education system into a fuzzy decision model.
