This paper suggests an e-learning system model, a goal-driven personalized e-learning system, which increase the effectiveness of learning. An e-learning system following this model makes the learner choose the learning goal. The learner's choice would lead learning. Therefore, the system enables a personalized adaptive learning, which will raise the effectiveness of learning. Moreover, this paper proposes a SCORM standard, which modifies SCORM 2004 that has been insufficient to implement the "goal driven personalized e-learning system." We add a data model representing the goal that motivates learning, and propose a standard for statistics on learning objects usage. We propose each standard for contents model and sequencing information model which are parts of "goal driven personalized e-learning system." We also propose that manifest file should be added for the standard for contents model, and the file which represents the information of hierarchical structure and general learning paths should be added for the standard for sequencing information model. As a result, the system could sequence and search learning objects. We proposed an e-learning system and modified SCORM standards by considering the many factors of adaptive learning. We expect that the system enables us to optimally design personalized e-learning system.

In this study, we developed mobile contents and mobile learning system for learning of english presentation based on Android platform. First, the application including contents transfer system which enables contents run on Android platform was developed for learning of English presentation. Second, presentation contents which will be applied on the application were manufactured. The contents developed in this study are for learning English presentations. The contents are classified into two parts; Part 1 is for basic English presentations, and Part 2 is for advanced English presentations. Each part is made up with 9 units, and each unit is composed differently by topics. The number of whole chapter for both parts is 51. We analyzed the questionnaire responses with respect to UI satisfaction and satisfaction of the learning experience. The UI satisfaction results showed that 85% of the participants were satisfied at an ordinary or higher level with our system. And The satisfaction of the learning experience results showed that 95% of the participants were satisfied at the ordinary or higher level with our system.

It is applying the various teaming contents to improve learner's studying desire and effect in E-Learning system. In this learning contents, there are text animation, sound and picture etc. But, multimedia teaming contents which has big file size need much transmission service times. In this paper, I proposed a scheduling technique of LMS to be faster and service efficiently the multimedia learning contents which was managed and processed it in LMS. for this purpose, I used message and scheduler at LMS. While loaming was processed, it saved the result information of learning contents request to LMS. In this case, if the learner request loaming contents request, it could be possible to support the learning contents efficiently to use learning contents information in LMS without connecting to LCMS. As application result of this techniques, at the first learning course, existent techniques displayed faster learning contents service than proposal techniques. But the more learning process, proposal technique is faster service than existent.

With the development of information communication and network technologies, ubiquitous era that supports various services regardless of places and time has been advancing. The development of such technologies have a great influence on educational environments. As a result, e-learning concepts that learners use learning contents in anywhere and anytime have been proposed. The various learning contents authoring systems that consider the e-learning environments have also been developed. However, since most of the existing authoring systems support only PC environments, they is not suitable for various ubiquitous mobile devices. In this paper, we design and implement a contents authoring system based on learning activities for u-learning environments. Our authoring system significantly improves the efficiency for authoring contents and supports various ubiquitous devices as well as PCs.

In this Paper, we design and implement an e-Learning system with dynamic learning contents Providing and re-time assignment system. The learner can select the dynamic learning contents Providing environments with test and Quiz Phase according to the learners' characters and interest to improve the learning effects. Also, we develop the real-time assignment system which is composed of multiple choice and essay test and can provide the interaction between teacher and learner immediately.

This paper aims at studying the new SCORM based e-Learning system and self-course design method. To construct this aims, we have researched the merits, shortcomings and characteristics of the previous LMS(Learning Management System) and we have researched the merits, shortcomings and characteristics of SCORM(Sharable Content Object Reference Model). SCORM was suggested ADL (Advanced Distributed Learning) to elevate the reusability of learning contents. Also we have researched the related researches of SCORM, SCORM based LMS and case studies. This paper suggests the level based self learning and course design and the system based on SCORM. This system has elevated the effectiveness and satisfaction of the learners.

Web based learning systems are operating with various and lots of learning contents. But it is hard to construct learning contents to fit learners when they select learning contents for learning. In this paper, we proposed the recommendation method that can support the learning contents as calculate learner's preference using the learning history information of learner's profile when learner design and compose learning course. In the applying result of this method, we've selected testing learner group and was able to know it can help to learner processing learning by themselves as we've got great learning satisfaction after test.

The purpose of the study was to develope e-Learning multimedia resource management system to support developing of e-Learning contents. This system is to create and manage multimedia resources like video, audio, and image more easily. We analyzed and redesigned media asset management system that would be used in broadcast, press, and industry. This system has SCORM metadata and is consisted of Windows 2003 server and RDBMS. The survey was conducted to investigate usability and satisfaction for the developed system.

The purpose of this paper is to study of the attitude of e-learning on the effectiveness of e-learning and the antecedents of e-learning. For this study, samples were collected in the school where e-learning was students of cyber lecture. Structural equation model was used to analyze the data. The result of this empirical study is summarized as followings. First, The attitude of e-learning has a positive effect on the e-learning effectiveness. Second, ease of use of learning management system, learning motivation, information quality of learning contents has positive effect on the attitude of e-learning, but usefulness of learning management system has no effect on the attitude of e-learning. Therefore, the former consists of learning management system, learning contents and information quality that are provided by e-learning and the latter means learning motivation.
