The emergence of any new technology in education gives rise to optimistic predictions of significant advances in learning. One of these technologies is an electronic learning system that often needs extensive hardware and software resources to provide a rich learning environment, that requires a great deal of cost to provide these resources. Cloud computing is the perfect solution for providing these resources at the lowest cost and providing rich services in e-learning. The purpose of this research is to study the technology of cloud computing and its advantages and limitations in order to improve the quality of education and learning. For this purpose, by studying the sources of recent years by library method, first while introducing cloud computing and its various services, its advantages and limitations in e-learning have been taken into account and then its solutions for improving the quality of higher education were studied. In the following, after discussion about mobile cloud services in education, the best model of using these services in e-learning and its success factors have been introduced. Based on the analysis, it was found that the best model for providing such services is hybrid cloud computing model and success factors in this case include the integration of education technology, teacher modeling, creating learning community, selecting Web 2.0 devices and softwares, technological and education support, and building sustainable engagement.

Entering the era of technology and domination of the Internet as an example of the of information and communication technology on this era have affected the human life of new era; But undoubtedly all parts of the world have not benefited equally from the technological and digital possibilities and this creates a huge gap between advantaged and disadvantaged countries; the gap that despite huge investments and governments efforts to fix, still has gripped some parts of the world. Digital literacy as one of the ways to settle this gap, involving skills that helps digital citizens- as people who must be familiar with security, legal and ethical behaviors to use digital technologies- to match their knowledge with era of information and achieve the highest utilization from the least physical facilities. The aim of this study is to evaluate the situation of the digital
divide in the current era and to provide some solutions to reduce this gap among digital citizens, therefore by explaining the concepts of digital literacy and digital divide, the causes of the digital divide are investigated and finally some solutions including setting up instructional programs, cultural domination practices and using the experiences of the pioneer countries are presented in order to settle this gap.

This research was conducted with the aim of evaluating electronic software quality applied at Allameh Tabataba’i university’s libraries (Pars Azarakhsh software) based on ISO 9126. The survey method was used in this research. The statistic population included all employees and managers of Allameh Tabatabaei university’s libraries were 35 people that 32 employees and managers of Psychology & Educational Sciences, Law and Political Sciences, Literature and Foreign languages colleges and free professional training center were selected by Morgan table and through Cluster sampling. The research instrument was a researcher-made questionnaire that its validity was confirmed by experts and professors and its reliability was calculated by Cronbach's Alfa that its value was 0.72. ​​Descriptive statistic manners (Frequency, Mean and Standard Deviation) and inferential statistic manner (One-sample T test) were used for data analysis. At the end of the research, this achieved result was that there is a straight and significant relationship between Pars Azarakhsh software quality with all six components of ISO 9126 quality evaluation model (maintainability, portability, functionality, reliability, usability and efficiency) and Pars Azarakhsh software is compatible with all six components of ISO 9126.

The aim of this study is comparing the effect of Dick & Carey instructional design model And Bybee instructional design model on students’ motivation and learning. The method of this study is Quasi-experimental and the research plan is pretest-posttest with two groups. The statistical society of this study included all female students in first year of high school in Shiraz. The statistical sample in this study was 54 female students and the available sampling was used. The data collection instrument was Herman's promotion motivation questionnaire and researcher-made learning test and in order to calculate the motivation questionnaire reliability, the Cronbach's Alfa method was used that its value was 0.87 and In order to calculate the reliability of learning test the Kuder Richardson 20 was used with the value of. /73. For data analysis, Covariance statistical test was used and the results showed that there is no difference between the Dick & Carey and Bybee methods in the rate of motivation, but there is a significant difference between Dick & Carey and Bybee methods in rate of learning and the Bybee method is more effective on students learning.

The main purpose of this study was comparing the effect of two teaching methods based on Dick & Carey instructional design model and Gagne instructional design model on motivation and learning in science at the first year high school students. The method of this study is Quasi-experimental research and the research design pretest-posttest with the two groups. The statistical society of this study included all female students of six year primary school who were studying in Shiraz city in the academic year 2013-2014. The statistical sample in this study was 54 female students due to limitation in implement was ran as an available sample. The data collection instrument was Hermans promotion motivation questionnaire and researcher-made learning test. In order to calculate the motivation questionnaire reliability, the Cronbach's Alfa method was used that its value was 0.87. In order to calculate the reliability of learning test the kuder.Richardson 20 was used that its value was 73%. For data analysis, Covariance statistical test was used and the results showed that there is no difference in the rate of motivation between Dick & Carey’s model and Gagne’s model but it was showed that there is a significant difference in rate of learning between the Dick & Carey model and Gagne’s model is more effective on students learning.

With the development of new approaches in education and progress in e-learning، evaluation has became a considerable challenge in this area. The purpose of this study is extracting the most important components، tools and methods of evaluating e-learning in order to achieve common points in these studies and presenting a comprehensive framework for evaluation of e-learning systems. In this study، the researchers used research synthesis method in which researchers selected 25 samples by purposive sampling among statistical population including 78 researches about e-learning evaluation and extracted the evaluation tools، components and methods were used in these researches and presented a framework for e-learning evaluation by analysis of these cases. The findings of this research include components، tools and methods used in e-learning evaluation in various researches and presenting a comprehensive framework in this regard. The results of this study showed that the most important components are usability، content and information quality، accessibility، communication، interaction and interfaces، management and controllability، technical system and services and supporting، also the most important tools for evaluation are questionnaire، checklist and interview and finally the most important methods are case study، survey and documental analysis.
