Most questions made for remote examinations on E-learning databank based selection system use methods of making questions automatically using degree of difficulty. This methods is the kernel of a question selection that degree of difficulty as make test questions, and then needs continuous management for degree of difficulty. This paper present improved algorithms for dynamically adjustment of degree of difficulty based on examination result that is more efficient set of question. We identified this algorithms is more effective as compared with previously algorithms on web-based education system.

In this paper the contention that a case study on the e-learning contents by students' levels. The Key word of the future e-learning contents are student-centered education that considers each student's ability, aptitude, and career choice. The major way to realize this student-centered education is to implement differentiated curriculum by students' levels. Especially, in the off-line class, this method Is very difficult because if superior and inferior classes are established, those who are placed in the inferior class will be hurt, but e-learning is realized that.

Modern society is rapidly changing by the Internet, and it is getting influential on the field of education. Learners can learn what they want to learn actively and freely at their desired level at anywhere in their free time by using the internet. The purpose of this study, therefore, is to find out the methods for improving writing ability through e-learning. The results of the study are as follows: First, learners can attend a lecture to improve their writing ability and can get learning materials from on-line course sites, internet websites, communities and blogs. Second, e-learning is learner-centered education, so it stimulates learners learning motivation and interest. Third, learners have an opportunity to express their ideas freely, and they can gain cultural comprehension while they communicate with people in the world by e-mail and chatting.

This study defined the characteristics of micro-learning emerging by mobile learning and micro-contents in the e-learning field, and analyzed the satisfaction of application, to see if micro-learning could become a new learning type in the future. To this end, the characteristics of micro-learning were defined through preliminary literature analysis, the characteristic satisfaction was verified in the well-equipped micro-learning site, and any other technical functions were suggested through expert opinion gathering. It was suggested that the future technology of e-learning should be linked to technical functions such as learning analysis and performance measurement. According to the results of this study, if micro-learning reflects its functional characteristics well, it will become an effective learning type in the e-learning field and will greatly contribute to education, learning, and training for the new millennial.

The appearance of Intelligent mobile and home appliance increased the using of not only various multimedia contents but also educational contents. Especially the growth of smart device such as smart phone, smart pad and smart TV, provided the environment which everyone can use educational content anytime, anywhere, any device. However many smart devices are hard to reuse the various educational contents because the devices and mobile os policies are not unify. In this paper, we suggest the design of NeS(N-Screen e-learning system) in order to solve this problem. NeS is consisted of User Management, Educational Content Management, Content Convert System and Interactive Management System. In this system, we use the HTML5 language to assure interoperability in various Smart Device Environment. Through NeS, we can achieve Content OSMU(One Source Multi Use) in various device environment and assure the continuity of the contents for using the educational contents more easily.

This study aims to explore the effect of quality factors and learning styles on users' satisfaction in e-Learning context. For this purpose, statistical methods such as reliability test, factor analysis, ANOVA, regression analysis were carried out using the survey data from university students. The quality factors of e-Learning were classified into contents, system, service, and interpersonal activities while learning styles were classified into positive-cooperative, self-directed, environmental-dependent, and passive styles. The results showed that each quality factors of e-Learning has a strong positive effect on user satisfaction, and self-directed group has higher satisfaction than other groups. Learning styles have moderating effects on the quality-satisfaction relationship, and especially, the group of passive learning style has a strong moderating effect on the interpersonal activities. Theoretical and practical implications and future research directions are drawn from these findings.

As information technology has been developed in a rapid way, a lot of users get to be familiar with social media. Accordingly, the possibility of social media for educational use has increased. From the view point of learning, social media help learners make communities of practice that can lead to collective intelligence. In this study, two different types of social media, synchronous and asynchronous, were compared in terms of usage patterns in the e-learning settings of college level. Content analysis has figured out four factors: learning content, tasks and assignments, emotional communications, and chatting. There found to be a statistical differences in the postings in all of the factors except tasks and assignments. In the qualitative interviews, the participants told various usage patterns of synchronous and asynchronous social media. In sum, the learners generally preferred synchronous social media. Rather, asynchronous social media were mainly used for deep thinking and summarizing. Last, suggestions were made to improve educational environments for the learners in the digital and social media age.

This study examines and measures the enhancement of intrinsic motivation in learners who have been part of the e-Learning system (www.englishbuddy.kr) for elementary-level English learning, developed based on the systematic application of the motivation theory as dictated by 'interest' and 'self-determination' and put into practice at 3,100 private tutoring institutions. According to the survey conducted on 328 learners in the e-Learning system inspired by the motivation theory and on 150 learners in other English programs, the former was found to have stimulated 'interest' and satisfied 'psychological desire' in the learners, leading to the development of 'specific strategies to motivate learners.' The study has clearly identified how learners are better motivated in the e-Learning environment, demonstrating its contributions to advancing e-Learning, building a practical e-Learning system based on a systematic motivation theory defined by 'interest' and 'self-determination,' and applying the system to some 16,000 learners at 3,100 private tutoring institutions.

This study is a study on the YouTube e-learning advanced service plan in the non-face-to-face era. The trends in education change were examined through literature research and prior research, and improvement measures were suggested through online surveys and in-depth interviews. As for the research method, the first online survey was conducted based on the Honeycomb model and the Likert 5-point scale targeting 90 MZ generation who have experience learning on YouTube for a total of 14 days from October 15 to 28, 2021. A second in-depth interview was conducted with 6 people who answered that the frequency of learning through YouTube is high. As a result of the experiment, users thought that there was an improvement point according to the purpose of learning, and they were able to derive elements that felt a problem in common. In addition, I proposed a new YouTube learning platform through additional questions. Through this study, it is expected that YouTube e-learning service reference materials can be used to respond to the post-non-face-to-face era.
