Design and Implementation of Learning Content Authoring Framework for Android-Based Three-Dimensional Shape

This study was conducted to create a more tangible educational environment by allowing learners to directly control three-dimensional learning contents through the touch interface of smart devices. Furthermore, because there are limitations to the acquisition and provision of three-dimensional learning contents due to difficulties in producing them, the proposed framework was designed to allow teachers and learners to directly produce and share contents. The proposed framework is based on intuitive XML language and the application was built to enable playback and authoring in Android-installed devices. In addition, a server environment was constructed for contents sharing. The feasibility of the proposed framework was verified through expert evaluation and its potential for utilization of new learning contents was positively evaluated.

Developing the Teaching Material and Comparative Experiment of LOGO and Scratch

Knowledge-based society requests the ability to reuse existing knowledge beyond acquirement and utilization of universal knowledge. The present education of computer, on the other hand, is biased only teaching how to use software. But it does not appropriate for the education to boost various and creative thinking. Thus, this paper carried out research on creativity to be treated in the goal of the 7th Educational Curriculum. Also it selected and analysed computer programming languages-`LOGO` and `Scratch`. Furthermore, it develops a training material and applies to elementary students in schools. The result that it compares and analyzes the effect that each languages influence to creativity of students, both of them help to develop creativity. Especially `LOGO` made a positive impact on fluency, `Scratch` did on ness and resistance.

A Study on the Development and Application of Programming Language Education for Creativity Enhancement: Based on LOGO and Scratch

Students meet with many problems during programming education in computer education. Programming education have been several research that are published that helps develop students’ creativity in the process of exploring solutions through flexible. Especially in elementary school students, receive training in programming for the first time feel constraint to lean programming language. But the use of EPL reduces difficulties. So Students can focus on the thinking. Therefore, in this paper, a draft was produced and applied to observe the creative elements increasing of elementary school students. And modify and supplement the draft through improvements to a draft obtained by applying.

Development of an Android Field Trip Support Application Using Augmented Reality and Google Maps

In this study, an application to support field learning was developed to apply to education Location Based Service (LBS) which is expanding with the spread of smartphones. To select functions in tune with the purpose, a requirements survey was conducted for current elementary school teachers, and the application was developed by reflecting the requirements based on an analysis of the survey results. Through the developed application, teachers can provide information to students and students can acquire information (location, pictures, description) required for field learning and carry out autonomous activities. The developed application was explained and demonstrated to current elementary school teachers who were given an experience of using it. A survey to verify its effectiveness was conducted and it was found that the application had a high potential for being utilized in field learning.

Development of the Educational Android Application using Location Based Service

Smartphone and Tablet PC has become a popular. So, various location-based service applications are being made in the field of advertising, games, and search. However, the location-based services application is lacking in the field of education. Therefore, this study proposes a Location-based service application for Tablet PC, which can be take advantage in school. The application was designed with these considerations in mind. First, the application to increase the participation of the students take the form of play. Second, participating students are influencing each other. Third, through the promotion of the cycle has allowed long-term operations. This application will be used usefully in an environment that students use a individual Tablet PC through the spread of e-textbooks.

A Development of Educational Material for EPL through Applying a Draft in Education -Focusing on LOGO and Scratch-

Students meet with many problems during programming education in computer education. In part of computer education, computer programming education have been researched. And the research have said that computer programming education have helped to increasing of students` creativity during find answer of problem through flexible thought. Especially, elementary school students, who learn to programming language for the first time, feel difficulty, when they learn computer programming. But the use of EPL reduce difficulties. So Students can focus on the thinking. Therefore, in this paper, a draft was produced and applied to observe the creative elements increasing of elementary school students. Than modify and supplement the draft through improvements to a draft obtained by applying. Also, made the educational material that can be used directly in the field.

Development Teaching Material for the Korea Information Olympiad Preliminary Round Test -Focusing on Elementary Students-

AbstractIn this study, the teaching material has been developed based on Polyas Problem Solving Techniques for preparing Korea Information Olympiad qualification and studying principle of computer. the basis of discrete mathematics and data structures were selected as the content of textbooks for students to learn computer programming principles. After the developed textbooks were applied to elementary school students of Science Gifted Education Center of J University, the result of study proves that textbook helps improve problem-solving ability using the testing tool restructured sample questions from previous test. We need guidebook and training course for teachers and realistic conditions for teaching the principles of computer. ■ keyword : ∣Korea Information Olympiad ∣Principles of Computer ∣Discrete Mathematics ∣Data Structures∣ 접수번호 : #100706-003접수일자 : 2010년 07월 06일심사완료일 : 2011년 01월 13일교신저자 : 김종훈, e-mail : jkim0858@jejunu.ac.kr I. 서 론 1. 연구의 필요성 IT기술은 우리 사회의 다양한 분야에 깊숙하게 관련함으로써 인류의 생활에 많은 변화를 가져다주었다.
