The purpose of thesis is to design and implement an efficient Internet-Based courseware which facilitates the problem solving learning. This courseware was developed in order to provide important foundations of learning in open-education environment using WWW. The targeted level is elementary students, To do this, the definition of problem solving, its processes, and advantages or pitfalls of computer-based problem solving learning were examined, with the advantage of using WWW as an educational tool. The theme of implemented courseware was selected from SATIS which is relevant for the problem solving learning. The courseware has three main parts; learning activity module, teaching activity module, and learning tool module. The learning activity module controls courseware flows and was implemented in accordance with the problem-based teaming processes. It: can be proceeded either sequential way or random access by setting linker. The advantage of random accessing method is that it may facilitate student learning because each student can regulate their learning processes which correspond to their own experiences. The teaching activity module provides for teachers useful informations for helping student's learning and it also can be used as an assessment tool for student's achievements, The learning: tool module consists of conversational note, e-mail address, help, and search tool. It is linked with learning activity module and teaching activity module so that teachers and students can actively participate in teaching-learning processes.

The purpose of this study is to design and apply cooperative learning using module cards for SW education for beginner and to analyze their effects and perceptions. Cooperative learning using 30 module cards consists of 3 activities and we applied it to elementary school students to verify the effectiveness of the learning. For the research analysis, we analyzed the pre-post motivation of SW education, the degree of satisfaction, interest level, and step recognition of the cooperative learning. As a result of the analysis, the learning motivation showed significant improvement in all areas of attention, relevance, confidence, and satisfaction. Students also found that the second stage of cooperative learning using module cards was the most interesting and the third was the most helpful.

오늘날과 같이 과학기술과 정보통신 기술의 급속한 발달로 인터넷이 다르게 성장하였으며 이로 인하여 다양한 학습용 사이트가 운영되고 있다. 따라서 웹상의 교육정보가 기하급수적으로 증가되었고, 이러한 교육용 웹 자료를 컴퓨터 보조 학습 매체로 활용하고 있다. 또한 CAI(Computer Assisted Instruction), ICAI(Intelligent CAI) 나 ITS(Intelligent Tutoring System) 등을 통해 컴퓨터를 수업매체로 활용하는 방법도 많이 연구되고 있다. 하지만 현재까지 개발된 대부분의 ITS들은 CAl나 ICAI의 이론적 특징을 살릴 수 있을 만큼 진보되어있지 못한 실정이다. 특히 현행 교육과정이 지향하고 있는 수준별 교육과정에 적합하지 않고 학생들의 능력, 적성, 필요, 흥미에 대한 개인차를 고려하지 않으며, 학생 개개인의 성장 잠재력과 교육의 효율성을 극대화하지 못하고 있다. 그리고 학습자가 원하는 요구를 정확하게 파악하여 학습효과를 향상 시킬 수 있는 방법을 제공하고 있지 않다. 따라서 본 논문에서는 학습자들의 개인차 변인을 파악하여 학습자의 요구나 능력에 맞게 학습자의 학업성취를 평가할 수 있고, 수준별 교육과정에서 학습 능력이 떨어지는 학생의 학습 결손을 예방할 수 있도록 인터페이스 모듈, 학습자 모듈, 교수전략 모듈, 전문가 모듈을 가진 자기 주도적 학습을 위한 웹 기반의 MITS(Multimedia ITS: MITS)를 설계하였으며, MITS의 각 모듈들이 효율적으로 상호작용 할 수 있는 알고리즘을 제안하였다.

본 글에서는 업무 종사자에게 실무에서 필요한 지식을 효과적으로 공급하기 위한 목적으로 지식을 실무의 관점에서 작은 모듈로 분해한 뒤 표준화하여 수요자에게 제공하는 체계인 국가직무능력표준(National Competency Standards: NCS)을 소개하였다. 파인세라믹 분야에 대해 개발된 NCS의 구성을 간략히 소개하였으며 활용될 수 있는 분야를 알아보았다. 또한 NCS에 대해 정합성을 갖춘 지식 제공 체계인 학습모듈의 구성을 소개하였다. 이와 같은 NCS 및 학습모듈의 활용을 통하여 지식의 수요와 공급에 대해서도 모듈화의 개념을 적용하고 필요한 지식이 효율적으로 유통되는 체계를 추구하였다.

본 논문에서는 간단한 비선형 시냅스 회로를 이용하여 온 칩 학습기능을 포함한 모듈 칩을 구현하였다. 학습 회로는 MEBP(modified error back-propagation) 학습 규칙을 적용하여 구현하였으며, 제안된 회로는 표준 CMOS 공정으로 구현되었고, MOSIS AMI $1.5\mu\textrm{m}$공정 HSPICE 파라메터를 이용하여 그 동작을 검증하였다. 구현된 모듈 칩은 온 칩 학습기능을 가진 확장 가능한 신경회로망 칩으로 대규모의 FNNs(feedforwad neural networks) 구현에 매우 적합하리라 예상된다.

Introduction of logarithm in mathematics textbook in the 7th national curriculum of mathematics is the inverse of exponent. This introduction is happened that students don't know the necessity for learning logarithm and the meaning of logarithm. Students also have solved many problems of logarithm by rote. Therefore, we try to present teaching unit for the logarithm according to the historico-genetic principle. We developed the learning-teaching module of unit for the logarithm according to historico-genetic principle, especially reinvention for real contexts based RME. Loaming-teaching module is carried out as the performance assessment. As a results, We find out that this module helps students understand concepts of logarithm meaningfully Also, mathematical errors of logarithm is revised after the application of learning-teaching module.

The earthquake education is the area that students have few opportunities to experience directly in elementary school earth science course. Therefore, I have developed an animation module to make students learn about earthquake efficiently satisfying students's interests and characteristics. I have planned to get the effective learning result by teaching 35 elementary students, using the developed module designed for ICT teaching and learning. The result of this study is that the animation module class gives students opportunity and develop students' attitudes towards earth science.

The robot soccer simulation game is a dynamic multi-agent environment. In this paper we suggest a new reinforcement learning approach to each agent's dynamic positioning in such dynamic environment. Reinforcement learning is the machine learning in which an agent learns from indirect, delayed reward an optimal policy to choose sequences of actions that produce the greatest cumulative reward. Therefore the reinforcement learning is different from supervised learning in the sense that there is no presentation of input-output pairs as training examples. Furthermore, model-free reinforcement learning algorithms like Q-learning do not require defining or learning any models of the surrounding environment. Nevertheless these algorithms can learn the optimal policy if the agent can visit every state-action pair infinitely. However, the biggest problem of monolithic reinforcement learning is that its straightforward applications do not successfully scale up to more complex environments due to the intractable large space of states. In order to address this problem, we suggest Adaptive Mediation-based Modular Q-Learning (AMMQL) as an improvement of the existing Modular Q-Learning (MQL). While simple modular Q-learning combines the results from each learning module in a fixed way, AMMQL combines them in a more flexible way by assigning different weight to each module according to its contribution to rewards. Therefore in addition to resolving the problem of large state space effectively, AMMQL can show higher adaptability to environmental changes than pure MQL. In this paper we use the AMMQL algorithn as a learning method for dynamic positioning of the robot soccer agent, and implement a robot soccer agent system called Cogitoniks.

Intelligent Tutoring System is composed of tutoring module, student module and expert module. Among the modules, interface module is the most closely related to students and shares the biggest part of a learning system. Interface module is important for students both in e-learning system but also in intelligent tutoring system. But research on the improvement of interface hasn't been actively done. It studied the interface improvement that has very close relation to e-Learning students. It studied the main components of the existing interface and designed multimedia interface to correct the problems of previous researches. It also suggested the method to relate it to the intelligent tutoring system.

수학적 지식과 능력을 활용하여 생활 주변의 여러 가지 문제를 해결하는 능력의 신장이야말로 수학교육의 목표이자, 수학 학습의 근본적인 이유가 된다. 그러나 문제해결 능력이 가장 많이 필요한 문장제 문제해결과, 문제 푸는 방법 찾기 단원을 학생들은 해결하기 어려워한다. 다른 단원보다 명확하게 식을 찾을 수 있는 연산 문제들과 다르고, 책에 제시되어 있는 방법을 쉽게 사용을 하지 못하며. 그 문제의 의미를 이해하지 못한다. 그래서 문제를 푸는데 즐거움을 느끼지 못한다. 이에 본 연구는 문제 푸는 방법 찾기 단원을 중심으로 문제해결 능력 신장을 위한 교수 학습 시스템 설계를 목적으로 학습의 과정별, 특성별, 연계별 학습 내용을 고려하여 학년 통합, 내용 통합하여 재구성하였다. 그리고 교수-학습 모듈, 평가 모듈, 상호작용 모듈로 시스템을 구성하였다. 시공간의 제약을 극복하여 학습자들의 수준에 적합한 개별화 학습을 제공하고, 웹을 이용한 문제 만들기 활동을 통하여 학습에 자신감을 기르고, 또한, 자기주도적 학습 능력을 향상시키는 계기가 될 수 있을 것으로 기대된다.
