The purpose of this study was to develop game style courseware in oral health instruction for elementary school children. The manufacturing equipment and languages which were used to develop the courseware were： Photoshop version 7.0, Illustrator version 10.0, HTML, Dream Weaver MX, Editplus, CSS and Java - script. The data base was built up by using PHP and mySQL over Internet Explorer version 4.0. The contents of courseware for oral health education were based on the list of oral health affaires of the Department of Health and Welfare, 2002. The story of the game ‘Saving Hayani locked down in a castle of a cavity man’ was developed for the learners to learn oral health by inducing learning motivation. A character named ‘Chan i’ was introduced to the learners to be more friendly with the program while they were learning. As the game was made of three step education levels, the learner most pass the prepared test given at each step to advance to a higher level. A database connected to web was constructed to store the scores the learners earned at each step. In conclusion, the courseware will help the elementary school children learn oral health care efficiently through the internet regardless of time and space.

Internet becomes absolutely necessary tools due to rapid progress of information technology. Educational correspondence abount an age of information demand is a education focused on a learner and remote education based on information technology. WBI(Web Based Instruction) is a formation that remotly educate a learner using web, possible mutual reaction between instructor and learner, submint various studying material, has a good point to overcome spatial restriction. Internal and external standardization working is accelerated and recently XML security studies are activated using XML which is next generation web standard document format. And XML electronic signature raise interworking between digital signature systems used by various field of using XML document. Using these merit and complementing defect are main contents that users have to pay about Certification service to get CA certificate from 2004 june. This paper propose multiplex Certification remote education agent system using XML digital signature to satisfy security requirement.

The value of Web in information societyis increasing in the field of education. Web Based Instruction (WBI) has an unlimited possibility of access the information. It also overcome the constraint of time and space more than the previous class learning method. The previous WBI system informed the results of study to learners after a professor's lecture and test was given. The uniform test didn't make the professor recognize the learner's evaluation according to the level of the learner and it couldn't be a reason to change a teaching method. In this paper, we discuss the Learning Evaluation(LE) component which can support a teaching method to teachers. We suggest LE component for supporting teachers as suggesting visually the test result of pre-test by step and post-test with several ways after analyzing, designing and realizing the evaluation of the test based on CDP(Component Development Process).

This paper proposes and implements an on-line instruction manual system which can generate the instruction manual page for the target device at the smartphone on the spot. The instruction manual app. on smartphone scans a QR code or reads NFC tag attached in the instruction manual management module embedded in the target device, and receives instruction manual data from the instruction manual management module through the Bluetooth communications and finally shows the refined instruction manual pages on the smartphone display using a Web-based templates. For the evaluation we embedded the instruction manual management module for an industrial generator with its instruction manual data. Assuming a circumstance of blackout we show that the proposed system can reduce the repair work within two steps compared to three steps in the existing one without the proposed system.

In this paper, we have designed and implemented Web-based realtime distant education system by using multimedia CAI and Java technology. The proposed system can provide not only Web-based courseware but also text-based text lecture and distant OHP in real time. The Courseware provides computer basic education and has been developed by using Authorware. The Client/server program of Text lecture and distant OHP for a realtime distant education has been developed by using Java applet and application. Java servlet has been used to construct CGI programs.

This study investigated the effects on young children's vocabulary and reading ability of the comprehensive language-teaching program using web-based picture books. The comprehensive language program was put into operation for 9 weeks with a classroom teacher who had in-service training for this program. The language course for the 23 children in the control group consisted only of ordinary language activities using teacher-made picture cards. Test results analyzed by t-test showed that the 25 children in the experimental group gained more than the control group on reading attitude including the concept of reading, accuracy, verbal expression, participation, contents and originality. Also, the ability to read a fairy tale aloud increased in the experimental group.

With the rapid growth of the Web technologies, the Web has changed teaching and learning as well as our life in various ways. Web-based instruction (WBI) supports self-directed and creative learning at anytime anywhere. However, learners may experience the problems of disorientation and cognitive overload when the hyperspace that consists of learning materials is complex. In this paper, we present a Web-based adaptive hypermedia system based on cognitive load theory which can reduce cognitive loads that novices may experience when they learn programming

The purpose of this study is to develop the model of constructivist multimedia-assisted instruction(CMAI) and to analyze the effect of it in the secondary school geography. The main results are as follows : (1) The conceptual model of CMAI can be defined as an instruction aiming at making a person who has self-directed learning ability through constructivism and multimedia. The procedural model of CMAI based on PIDA instructional strategy is divided into four stages : prediction & explanation, inquiry activity, discussion & fixation, application & synthesis stage. (2) CMAI is typed by offline CMAI and online CMAI. that is, O/WCMAI(online CMAI by web-based courseware). Offline CMAI is subdivided into P/TCMAI(offline CMAI by presentation-based courseware) and C/RCMAI(offline CMAI by cd-rom based courseware) according to authoring tool and function. (3) Offline constructivist multimedia course-ware(offline courseware) was developed for 2 periods as the material to analyze the effect of CMAI. Offline courseware is received development level of it. (4) After offline courseware being applied to the class, the effect of it according the types of the CMAI instruction(lecture instruction, whole teaching, individualized learning, cooperative learning) was analyzed. As the result of analyzing the descriptive statistics of the level of learning achievement and instruction response, there isn't big relationship between them. As the result of analyzing the inferential statistics of the level of learning achievement, there wasn't significant difference between the types of CMAI instruction in whole student of the classes and certain students who improved their grades. But as the result of analyzing of the level of instruction response, there was significant difference between lecture instruction and other types of the CMAI instruction(whole teaching, individualized learning, cooperative learning).
