Under the circumstances of general use of Internet, the construction of on-line system has been made in various fields. We can use and share the informations will other people through the cyber communities and find many ways to promote communication tools. Project Room is a sort of Cyber Space which carry out design project using On-fine system. Users(Designers and Clients) will be able to develop their design project using Internet. The project content may be opened and will be critically contributed the construction of Knowledge-based industry. At the same time, the development of user-friendly tutorial should be fellowed. Tutorial is one of the most important factors to promote Project Room. This study presents the possibility of execution of Cyber community under the construction of Project Room and User-friendly tutorial in the On-line system.

The purpose of this study was to review the literatures on designing and developing the CAI program and to develop the middle school students’CAI program for tutorial and instructional game. For these purposes, the learning and instructional theories and the developing phases and strategies for the program were reviewed to design the CAI program. And then the developing unit was selected and the CAI types and the developing direction were set according to the analysis of the CAI programs and related literatures on home economics teaching, The four phases-analysis, design, development, and formative evaluation-were carried out in this study. The results of this study are as following: 1. The CAI porgram was developed on health and food life units. The program contains 12 classes on health and food life in two floppy diskettes. It consisted of total 9,000 lines and 76 frame and takes two hours to study this program. This program could be used in educational computers an could be utilized for unit learing tutorial. It was composed of three parts-unit learning, finding maze, and finding food. In the unit learning part, the learning contents in health and food life units were structured and presented. In finding maze and food part, the basic and the applied problems were presented with game. The characteristics of this program were as followings: (1)This program was able to bring learners’motivation due to the strategies of tutorial and instructional game and they can interestingly learn the program for themselves. (2) The learner could practive the learning contents repeatedly and unit learning while playing the gaming, (3) The learner himself can review and supplement the learning contents without teacher’s help. (4) This program was developed to unit learning on health and food life, on the other hand so far many CAI programs for home economics teaching were developed for studying separate learning units. 2. To effectively utilize this program, the guide book for the student and the teacher was developed. It contained method of using the program, introduction of the program, review of the program, the program objectives, the learning contents, and the keys to progress the program.

We constructed an intelligent tutoring system that compose four devices i.e. intelligent interface, acqusition module, tutoring controller and tutorial knowledge. We implemented the intelligent tutoring system using prolog as an authoring language in the ultrix os under VAX-11/750, and we propose goal opriented tutoring system algorithm.

The purpose of this paper is to investigate the effects on academic achievement for university basic mathematics in order to improve the problem-solving abilities of low achievement students in university general mathematics. In this paper, we suggest effective management strategies and teaching-learning methods according to level-based classes with utilizing scholastic level assessment, students survey, Mathematics Cafe and tutorial program, and also managing demonstration classes which are using Webwork system for assignments and evaluating the class.

Purpose: This study was attempted and completed in order to settle down and qualitatively improve web-based nursing education by evaluating effect and managing strategy of tutor. Method: The development of tutor's managing strategy was based on "The Self-regulated Learning" and "The supportive Learning", then it was applied to 79 learners in one of the cyber-learning centers. After applying the tutor's managing strategy, self-regulated learning scale, attitude for school, preference for computer and academic achievement were evaluated. The development of tutor's managing strategy for web-based nursing education are consisted of participation promotion, psychological support and motivation, recognition and promotion strategy of learning activity, management strategy of evaluating stage. Result: The levels of learner's self-regulated learning, recognition, behavior, attitude on the school and learning achievement were meaningfully increased in statistics after applying for the managing strategy of tutor. The motivation level and learning participation kept high scores from the beginning with no significant statistical changes. Conclusion: It is required to develop an educational program for cultivating well-educated tutors in order to help the effective learning process of nurses based on understanding characteristics of learners.

Recently, extensive studies have been conducted to apply deep learning to reinforcement learning to solve the state-space problem. If the state-space problem was solved, reinforcement learning would become applicable in various fields. For example, users can utilize dance-tutorial systems to learn how to dance by watching and imitating a virtual instructor. The instructor can perform the optimal dance to the music, to which reinforcement learning is applied. In this study, we propose a method of reinforcement learning in which the action space is dynamically adjusted. Because actions that are not performed or are unlikely to be optimal are not learned, and the state space is not allocated, the learning time can be shortened, and the state space can be reduced. In an experiment, the proposed method shows results similar to those of traditional Q-learning even when the state space of the proposed method is reduced to approximately 0.33% of that of Q-learning. Consequently, the proposed method reduces the cost and time required for learning. Traditional Q-learning requires 6 million state spaces for learning 100,000 times. In contrast, the proposed method requires only 20,000 state spaces. A higher winning rate can be achieved in a shorter period of time by retrieving 20,000 state spaces instead of 6 million.

In recent creativity becomes a new request in the knowledge and information age. Robot programming education is an effective teaching method for improvement of creativity. Existing robot programming tools includes text-based or GUI-based development environment. Most of programming tools provide a simple tutorial system without interactive activity for beginners. In this paper, we propose an online robot programming education system based on web2.0, which embedded collaborative code creating tool, interactive tutorial chat and video conference tool to support collaborative code creating via web 2.0. Knowledge sharing tool allows users to share their collaborative source code. Besides, it makes users gained the experience and knowledge of program designing efficiently.

이 연구는 전하 이동을 강조한 튜토리얼을 통하여 초등 교사의 전기 개념 변화를 분석하고, 초등 교사 교육을 위한 시사점을 얻는데 있다. 튜토리얼은 사전검사, 워크시트, 사후검사로 구성되었고, 내용은 두 개의 대범주인 정전기 영역과 전류 영역으로 이루어졌다. 현직 초등 교사 68명에게 튜토리얼을 적용하고 선택형 질문지, 사전 검사, 사후 검사, 워크 시트, 튜토리얼 과정 녹화 전사본 및 면담을 통하여 초등 교사의 전기 개념 변화를 분석하였다. 연구 결과, 교사들은 도체와 부도체의 전기적 특성에 대해 이해하게 되었는데, 마찰과 유도, 접촉에서 전하들의 움직임을 고려하고 설명할 수 있게 되었다. 그러므로 대전과 전류를 혼동하는 어려움이 해소되었다. 열린 회로에서는 전압을 전하가 받는 힘을 고려하여 이해할 수 있게 되었고, 축전기를 통해 일시적 전하의 이동을 설명할 수 있었다. 이것은 전압이 전류의 결과라는 오개념을 과학적 개념으로 바꾸는데 중요한 역할을 하였다. 닫힌 회로에서는 전구 양단에 쌓이는 전하들의 분포를 강조함으로써 회로에서 전류가 소모되지 않고 일정함을 이해하게 되었고, 직렬과 병렬에서도 각 회로에서 전구 양단의 전하들의 분포를 고려함으로써 회로에 따라 전지의 역할이 달라짐을 이해할 수 있게 되었다.
