In this paper, this app is an online learning tool web application that helps learners learn efficiently. It discusses how learners can improve their learning efficiency in these three aspects: retrieval practice, systematization, metacognition. Through this web service, learners can proceed with learning with a flash card-based retrieval practice. In this case, a method of managing a flash card in a form similar to a directory-file system using a composite pattern is described. Learners can systematically organize their knowledge by converting flash cards into a mind map. The color of the mind map varies according to the learner's learning progress, and learners can easily recognize what they know and what they do not know through color. In this case, it is proposed to build a deep learning model to improve the accuracy of an algorithm for determining and predicting learning progress.

In the recent field of education, they open career-related curriculums either as formal curricular programs or extracurricular programs as highlighting value of career education. However, this lecture-based career education has failed to attract students' interest, and results are not satisfactory either. Since then, in order to design entertaining career education, the field has developed diverse tools and as a vocational aptitude testing tool for career development, methods that would use vocational cards were introduced. Today, schools from elementary school to middle and high schools frequently make use of the cards to conduct the vocational aptitude test and yet, as this web-based learning and smartphones are distributed, changes in the testing tool are being intensely demanded. This study aims to create and implement an application to help the vocational cards-using vocational aptitude test targeting students in elementary, middle and high schools to be actually conducted in a mobile platform.

본 논문에서는 웹 기반 강의 컨텐츠의 문제점을 알아보고 그 문제점을 해결할 수 있는 방법을 제안한다. 다시 말해서, 기존의 웹 기반 강의 컨텐츠는 HTML을 기반으로 한 획일적인 하나의 큰 파일이거나 미디어 제공 벤더에 종속된 저작도구로 작성된 파일이다. 이러한 강의 컨텐츠는 서로 다른 가상교육 시스템에서 공유하거나 재사용하기가 어렵다. 그래서 본 논문에서는 분산 컴퓨팅 환경에서 가상 교육시스템들이 공유할 수 있고 재사용 할 수 있도록 강의 컨텐츠를 속성을 가진 더 작은 크기로 분해하여 객체화하는 방법을 제시한다. 특히 교수법(pedagogy)적인 설계 방법론에 근거하여 강의 컨텐츠를 분해 및 객체화하여 강의 컨텐츠의 학습 이해도를 높였다.

우리나라에는 영어 학습을 위한 수많은 도구들이 있다. 특히, 최근 스마트폰의 출현으로 영어 학습을 위한 어플리케이션 개발이 활발하다. 그러나 대부분 영어단어를 단순히 암기하는 방법에 관한 것으로 텍스트 분석에 대한 어플리케이션은 부재하다. 본 논문에서는 사용자가 텍스트를 입력하면 단어가 갖고 있는 희소성에 따라 온톨로지 기반으로 분석되어져서 등급을 매기는 어플리케이션 시스템을 제안한다. 결과물은 파일 시스템과 데이터베이스에 저장되어 사용자는 텍스트의 희소성에 따라 선택한 텍스트를 읽음으로서 사용자의 눈높이에 맞게 신속하고 효율적인 어휘획득 능력을 갖게 된다.

교육인적자원부의 ${\ulcorner}$초${\cdot}$중등학교 정보통신기술 교육 운영지침${\lrcorner}$에 따르면 각 교과 수업 시간에 ICT 활용 교육이 $10\%$이상 반영되도록 적극 권장하고 있다. 이에 따라 각급 학교에서는 전통적인 학습 지도안과 ICT 활용 교수-학습 과정안의 두 가지 형태를 병행하여 사용하고 있으나 작성 도구와 형식이 다양하여 교사들 상호간의 문서 공유와 재사용성이 떨어지며 웹 상에서 정확한 검색이 어렵다. 본 논문에서는 한국교육학술정보원에서 제시하고 있는 ICT 활용 교수-학습 과정안의 모형을 토대로 공통 DTD를 설계하고 데이터베이스와 연동하여 표준화된 XML 문서를 생성함으로써 교사들 상호간의 공유 및 재사용성을 높이고 정확한 검색이 이루어지도록 하였다. 또한 유선 인터넷 서비스와 동시에 무선 인터넷 환경에서도 WML을 이용하여 모바일 서비스가 가능하도록 구현되어 있어 보다 향상된 교수-학습 환경을 제공할 수 있다.

The purpose of this paper is to present the effective operation method of cyber home learning system 2.0. Cyber home learning system 2.0 which plays an important role to produce and share data of internet users establishing user-centered internet environment is recently introduced as web 2.0 is beginning to appear. This research is based on the case of the operation on cyber home learning system, research literature of web 2.0 as well as expert consulting and performance test. After doing this research, cyber home learning system 2.0 can bring enormous educational effect when it has online education using web-based discussion tool and long distance consulting linking with off line school education. Redundant system configuration, the distributed processing also may be provided by the service was smooth. Moreover, it demands monitoring team consisting of student, parents and teacher in order to provide developmental service.

Preparing the 4th industrial revolution age, a diagnostic assessment management system which can collect nationwide data has been implemented and utilized for the development of the evidence-based educational policy. This study aims to develop heuristics to help to improve usability of such systems, which are utilized by primary and middle school community including teachers and students in the nationwide. To achieve the objective, previous studies related to the development of heuristics in the educational contexts as well as basic heuristics from Nielsen were reviewed, and usability problems of the web-based diagnostic-supplement system being currently utilized, as a sample system, were analyzed. Then, the first version of heuristics was developed. The developed heuristics were validated and revised through 2 rounds of the delphi methods with 15 experts. This study has an implication with preparing foundations on improving usability of such diagnostic assessment management system utilized by school community at the nationwide in educational contexts.

Elementary school students have a great deal of interest in Internet games which provide integrated multimedia and so they become to know well the terminology used in network such as game server, Internet service, transfer time, etc. In addition, they are used to understand the technological phenomena occurring in internet. They, however, have difficulty understanding concepts and principles regarding the phenomena mentioned above because the educational contents in elementary school computer textbooks consist of only ICT education and its applications, i.e., tool-based technology. In this paper, we apply educational learning on network concepts which are the basis on the internet to classroom instruction by using problem oriented models. We conclude that the educational contents in elementary school computer education should be transferred to the area with principles and concepts.

Learning Diagnosis & Prescription Service(LDPS) in Cyber Home Learning System is a educational service which provides customized learning contents based on student's academic level and individualized counseling and comments after diagnosing learner's study habits beyond the past e-Learning systems which offer the same contents to different students. For a national point of view, it is a crucial project in public education to achieve the goals of the next-generation e-Learning service by making a lot efforts both in time and money. However, those efforts has been made, not in terms of providing a better quality of service and a better user experience in a effective and enjoyable way, but in terms of developing the technology-driven system. Therefore, in this study, two types of usability evaluations has been conducted in order to enhance a user experience on the LDPS. One is the expert reviews by utilizing the usability evaluation tools (heuristics) which was focused on educational contexts developed by Suh Young-suhk(2007). The other is the user testing with students who have done think-aloud during the evaluation, remembering their retrospective experience with LDPS, and the interview with teachers & service operators were conducted. As the implications on the research, this is an effort to provide an user-friendly educational system for the students nationwide.

In the environment of emphasizing creativity, computer application instruction model is in demand which is developed for the group discussion, enlarging the range of thinking, and creativity. The purpose of this study is to develop a PBL-based computer application instruction model concerning creativity after researching problems during the use of computer education by group. The theoretical background of class model is PBL, and the efficiency and creativity of class is considered while using web-mind map as the tool for the discussion and data sharing. As a result of applying the suggested model to the students enrolled in the production of presentation instruction, it made probabilistic meaningful outcome where complaint with communication, data sharing, role sharing, difference of contribution, excessive run-time and etc. were reduced.
