The present study aims at identifying the appropriate approach to improve the quality of e-learning in Payame Noor University. The research is applied in terms of purpose, is descriptive in terms of nature, and is a mixed method in terms of implementation applying an interview and a survey. The research population consists of all professors and students in e-learning department of Payame Noor University studying in academic year of 2016-2017. The research samples, consisting of 327 students and 291 professors, were selected through stratified random sampling. For data collection, in the first stage, after reviewing the related literature and conducting a semi-structured interview with distance education professionals and experts, the quality indexes in e-learning were identified. Then, in the second stage, two researcher-made questionnaires, based on a 5-likert scale, were prepared and after verifying the content and construct validity and calculating the reliability through Cronbach's alpha formula above 0.70, they were distributed among students and professors. The results of study suggest that if we are to take steps to improve the quality of e-learning in PNU, in addition to paying attention to maintaining the current quality and keeping its improvement through two components of strategies, policies, and general objectives and technology infrastructures, which had the greatest impact on e-learning quality, we should also take action through these factors to increase the impact of other components. Also, in order to improve the quality of e-learning in PNU, strategies such as paying attention to the quality of interaction, preventing significant changes in management decisions at the university, and paying attention to the empowerment of all human factors were suggested.

This study investigated the relationships among self-regulated learning, motivation for academic achievement and self-concept in prediction of academic achievement of male high school students studying through distance education system in Kashan Province, Iran. A cross-sectional, descriptive- correlational design  was conducted among all male high schools students in Kashan’s distance education centers during 2015-2016(n=718). Using a multistage cluster sampling, 270 students were selected. Data were collected using Herman’s achievement motivation questionnaire (1970), the Pintrich & De Groot self-regulated learning scale (1990) and Becks self-concept scale (1990). Stepwise regression analysis was employed in the SPSS version 20. The results showed that self-regulated learning, motivation for academic achievement and self-concept had significant positive relationships and predicted academic achievement statistically (p

The study tried to examine the possible effect of multimedia materials on augmenting listening skills of girls in Meheaval higher secondary school, Karaj city. The next purpose was to detect whether there is a meaningful relationship between students’ attitudes towards using multimedia materials and teaching listening skills. The participants of this study were 60 second-year high school (EFL famale students) in the second semester of 2016 academic year. The homogeneity of the participants was ensured through application of the Oxford Placement Test (OPT, 2001).  The materials was comprised of students’ textbook and Listening Assisted Multimedia. Three types of instruments which were utilized namely, listening comprehension pre-test, post-test, and a listening assisted multimedia questionnaire. Independent samples t-tests and regression coefficients were applied to determine whether there were significant inter and intra-group differences. The results showed evidence that multimedia materials significantly enhanced EFL learners’ listening achievement. It was also found that the attitude to the use of multimedia had a statistically significant impact on explaining the changes in learners’ listening skill. Based upon the findings of the study, it is recommended that the English instruction should be integrated to the English instruction listening course.  Key words: Multimedia, Listening, Listening Assisted Multimedia Questionnaire

Aims: We investigated gender differences among adolescents in quality of sleep, psychophysiological problems, dream frequency, emotional states, and personality traits and also if the effect of quality of sleep on psychophysiological problems, dream frequency, emotional states, and personality traits was moderated by gender. Method: High school pupils (n1 = 155, n2 = 142, and n3 = 325) responded to the Uppsala Sleep Inventory, the Positive Affect Negative Affect Schedule, Beck’s Depression Inventory, the Type A-Personality Scale, and the Temperament and Character Inventory. Gender differences were investigated using Multivariate Analyses of Variance and moderation using multi-group Structural Equation Modeling. Results: Girls scored higher in major sleep problems, difficulties falling asleep, night awakenings, psychophysiological problems, dream frequency, negative affect, depression, stress, and Type A-personality. Boys scored higher in novelty seeking, harm avoidance, and persistence. Girls’ quality of sleep was related to their psychophysiological problems, dream frequency, positive affect, negative affect, stress, novelty seeking, reward dependence, persistence, and self-directedness. Boys’ quality of sleep was related to their psychophysiological problems, negative affect, stress, Type A-personality, novelty seeking, harm avoidance, reward dependence, and self-directedness. Conclusion: Girls showed the unhealthiest sleep-psychophysiological-emotional-personality profile. For both genders, good quality of sleep or “beauty sleep” might result in less psychophysiological problems, less negative affect, less stress, less novelty seeking, and less self-directedness. However, for boys, “sleeping beauty” comprises less Type A-behaviour, ss harm avoidance, and more reward dependence; while for girls “sleeping beauty” comprises less frequency of vivid dreams, more positive affect, less reward dependence, and more persistent behaviour.
