It was essential to develop the DB-type teaching and teaming material for geography instruction using a method of ICT. The DB-type teaching and learning material was considered as a alternative in solving the problems of web-based geography instruction. Accordingly, in this study, the geography image DB program as developed, and based on this program the CD-ROM called GEO-DB, having the function of electronic dictionary of geography image for geography teaching and teaming was made. The GEO-DB was composed of 3,060 geography images collected by teachers and learners. The GEO-DB was made to be used simply by teachers and learners. Especially, the portfolio function was Included in the GEO-DB, and that was focused to the instructional system design of teacher and the self-directed teaming ability development of learner. Teachers and learners using this GEO-DB assessed that because the GEO-DB had the easiness of use, the speed of reference and the unlimitedness of extension, it could enlarge the possibility of using a method of In, and it could contribute to the development of geography teaming ability and the change of geography teaming attitude.

인터넷의 방대한 자료 중 필요한 자료만을 선별하고, 분석.종합하여 유용한 정보를 도출하는 능력이 더욱 더 요구되고 있다. 유용한 정보를 도출하기 위해서는 컴퓨터가 가지고 있는 정보처리 능력을 최대한 활용할 수 있어야 하며 교수자는 학습자에게 문제해결을 할 수 있도록 정보활용 능력을 길러주는 것이 교수자의 역할이다. 본 연구는 WWW에서 학습자와 학습자료간의 상호작용이 가능하도록 하였으며 학습자 상호간에도 상호작용이 가능하도록 공동학습장을 마련하였다. 또 교과학습을 효율적으로 하기 위해 홈페이지 제작학습 및 정보 검색방법, FTP 사용법, 압축/해제하기 등을 탑재하여 효율적인 정보활용을 위해 기본적인 도구들의 사용법을 습득할 수 있도록 하였으며, 학습자가 인터넷 홈페이지를 활용하여 과제 학습을 자기 주도적으로 해결함으로써 정보활용 능력을 신장시키는 시스템을 제안하였다.

This study was done to explore the correlation among self-determination, learning commitment and learning outcomes and identify factors related learning outcomes under academic credit bank system. The survey was conducted self-report questionnaire. The data collection period was form April to November 2018. Participants were 144 registered nurses working currently under academic credit bank system. Collected data were analyzed using SPSS/WIN 24.0. Learning outcomes had a positive correlation with self-determination and learning commitment. learning commitment. Self-determination was positively correlated learning commitment. Factors affecting learning outcomes included self-determination and learning commitment. And self-determination and learning commitment accounted for 32.1% of the variance in learning outcomes. Therefore, developing learning outcomes support for improving self-determination and learning commitment. Future research will be needed to clarify the effects of learning outcomes promotion program on self-determination and learning commitment.

정보통신기술의 발달은 학습자들에게 시간과 공간의 제약을 벗어나 자신이 원하는 시간에 학습할수 있는 환경을 제공하게 되었다. 이런 환경하에 등장한 WBI 는 학습환경의 큰 변화를 야기하였다. 그러나 이런 WBI만으로는 학습효과를 가져올수는 없다. 그 이유는 모든 학습자들에게 고정적이고 일률적인 학습자료는 다양한 학습자들의 수준과 학습능력 등 개별적 특성을 효과적으로 반영하지 못하기 때문이다. 개별학습을 위한 WBI는 학습자들의 학습효과 증진을 위해 학습자들의 다양한 특성을 반영하여야만 한다. 본 논문에서는 '컴퓨터활용능력'자격증을 취득하기 위한 개별학습시스템을 통해 학습자들의 수준에 맞는 학습자료의 제시와 개인성적정보를 통한 학습효과를 증진, 테스트후 점수의 부족한 세부영역의 제시를 통해 학습자의 개별성을 효과적으로 반영할 수 있는 WBI를 구현하고자 하였다.

The purpose of this study was to design and implement the smart system for supporting instructional materials employing characteristics of smart education and flipped learning and to examine the effects of the system on students' achievement and satisfaction in elementary education. The system was developed on the basis of the curriculum with the design strategies of the smart system. The results of the analyses showed that the achievement of the students was increased over the series of the tests. It was also found that the system positively influenced students' self-directed learning time and their satisfaction in social studies education. The implications of the results of the study and suggestions for the future study were discussed.

시계열 자료를 분석할 때 쉽게 접근하는 통계적 방법은 ARMA 모형이며 신경망 학습 방법 중에서는 다층 퍼셉트론에서의 Back-propagation 알고리즘이 일반적이다. Back-propagation을 비롯한 신경망 학습의 구조는 자료의 특성에 따라 경험적으로 결정하는 것으로 알려져 있다. 그러나 바로 이 점이 신경망 학습방법의 이용을 어렵게 하는 요인이기도 하다. 본 연구는 ARMA 모형 중 몇 개 유형의 자료에 대하여 Back-propagation 알고리즘을 적용함에 있어 어떠한 구조로 학습하는 것이 효율적인가를 입력층과 은닉층의 크기, 활성화 함수를 중심으로 검토하였다.

본 연구에서는 시계열자료를 예측하기 위해 적용한 n$\times$n$\times$1 신경망 구조에서 초기값의 시각적인 선택을 통한 개선된 학습과정을 제안한다. 적용된 Easton[1]의 제어상자는 시각적인 면과 실용적인 적용측면에서 다차원 구조를 논의하기에는 제한적이지만, 적은 개수의 은닉노드를 갖는 단순한 신경망구조에서는 초기 가중값들의 동적인 선택을 통하여 가능한 빨리 효과적인 학습이 이루어질 수 있게 할 수 있다. 신경망 학습의 오차 판단기준은 기존의 평균제곱오차(MSE)를 고려한다. 실증연구에는 모의생성된 ARMA(1,0) 자료와 담배생산량 자료를 이용한다.

Although the current Web search engines provide tremendous information, it is hard to find right information among the huge information. Users need to spend extra time to filter out unnecessary information. In order to overcome the limit of current Web search engines, Semantic Web was developed to provide efficient search, integration, and reuse of information by structuring semantic information from Web resources. In this paper, an elementary education contents retrieval system using Semantic Web is proposed. The proposed system emphasizes history contents that have high relevancy among data. For construction of the proposed system, ontology is proposed first for elementary study contents and ontology for historical contents is proposed for easy access to those contents using semantic relation among them. Based on the ontology, the proposed system is designed and implemented. The proposed system has the following characteristics. First, the system provides various query formats in detail so that search results can be refined efficiently. Second, the system presents only semantically information connected with key words or including key words using study contents ontology. Finally, the proposed system can increase study effects by presenting various contents that are related with query by users.

CS Unplugged education is emphasized as the component of the basic principles of Elementary SW education. This document produced by two other Timbell presents the contents in a variety of topics about computer science. One of the main components is the finite Automata, and this requires the development of educational materials for teaching our situation. So We'll present the finite Automata learning materials for elementary school classes. Learning model that we have presented is a process of self-directed and activity-based learning. For verification of this experiment was the validation of the expert group and was concluded that adequate through the analysis of the diagnostic tests.
