The purpose of this study is to compare and analyze the impact on low-achievers in mathematics who studied mathematics using Blended e-learning and Personalized system of instruction after school. Blended e-learning is defined as the management of e-learning using the e-study run by the education office in local. Personalized system of instruction was proceeded as follows; (1) all students are given a syllabicated learning task and a study guide, (2) students study the material autonomously according to their own pace for a certain period of time, (3) the teacher strengthens the students' motivation through grading and feedback after students study a subject and solve the evaluation problem. The learning materials for Personalized system of instruction are re-edited the offline education contents provided by the blended e-learning to the level of students. The 118 $7^{th}$ grade students from the D middle school participated in this study. The results were verified by achievement tests before and after the study, as well as survey regarding their attitude toward mathematics. The results are as follows. First, Blended e-learning has more positive impacts than Personalized system of instruction in mathematics achievement. Second, there was no difference in mathematics achievement according to their self-directed learning between Blended e-learning and Personalized system of instruction. Third, both types utilizing Blended e-learning and Personalized system of instruction have positive effect on attitude toward mathematics, and there is not their difference between two methods of teaching and learning mathematics.

The purpose of this investigation was to help university professors for making their systematic design of instruction easily and scientifically. To increase of learner's studying ability, the systemic instructional design is imperative. But most of university professors could not get proper experiences to know develop instructional design system, specially to develop web-based system. This new system made it possible to select the proper instructional methods and the media type suitable for the corresponding data. And also every professor who is involved to know this system, can put informations for the target learners, learning contents and learning objectives, and present the proper media types and the many different conditions in the process of the each instructional design process. Finally, the results of the learner's study will be effective and professors showed their positive opinions for the using of the system.

In order to satisfy the gifted students' learning desire and maximize the effectiveness of their learning, we constructed the system which would provide them with supplementary activities based on the Internet boards. At the very beginning, we investigated the personalities of the gifted and their classroom environment which they prefer through studying the related references and asking questionnaires. And then we discussed how to improve the lectures, decided to make the basic structures of the web-based supporting system, and designed some teaching strategies for the gifted. which are named 'GIFTED'. Now the web-based supporting system, which are composed of several boards, was established and is being operated now. Each subject has its own boards. The boards of each subject basically consist of Notice, Learning-materials, Q&A, Homework, Recommended Sites. The results we've got from operating our system are following: Teachers and students were generally satisfied with the system while students wanted more materials. Students and teachers had a positive attitude that the site boards of Learning-materials and Homework are being actively used, while the numbers of contents uploaded in Q&A and Recommended site boards are small and they are regarded as being unimportant to the students and teachers.

인터넷 웹 기반 교수-학습체제는 학습자 위주의 교육환경으로 변화하였고, 웹 환경에서도 학습자에게는 시간과 공간의 제약에서 벗어나 다양한 교육정보를 접할 수 있는 원격교육시스템이 대두하고 있다. 인터넷의 발달은 교육환경에도 많은 변화를 가져오고 있다. 이러한 변화는 인터넷을 이용한 웹기반 원격교육이 여러 분야에서 폭넓게 응용되고 있음을 대변하는 것이라 할 수 있다. 하지만 기존의 원격강의시스템의 경우 교사가 학습할 내용들을 파일형태로 업로드해 놓으면 학습자가 다운로드하여 쓰는 방식이어서 많은 전송비용과 강의내용 구성이 단순한 텍스트 위주의 형태로 구성되어 학습자의 학습효과가 의문시 되었다. 이는 학습자 위주의 자기 주도학습에 많은 어려움을 유발시켰다. 따라서, 본 논문에서는 고등학교 정보산업교과의 [인터넷] 단원에 대한 학습을 체계적으로 언제 어디서나 학습할 수 있도록 이론과 실기강의내용을 웹을 통하여 교육에서 요구되는 음성과 교재 판서의 기능을 웹상에서 구현할 수 있도록 되어 있다. 이런 멀티미디어 자료들이 동기화되어 자기 주도적 학습을 할 수 있는 멀티미디어 원격강의시스템을 구현하였다. 본 연구의 원격강의시스템은 멀티미디어자료 들을 활용한 원격강의시스템이기 때문에 개별화된 교육과 자기 주도적 학습을 통해 시ㆍ공간의 제약을 받지 않고 학습 할 수있는 진정한 원격강의시스템이다.
