This study aims to understand the overall experiences of students who use notebook computers in class by using a qualitative approach. Interview data were collected from 23 Korean college students at a Korean university, who use notebook computers in their classes; the data were analyzed through the constant comparison method. The results from this study can be categorized into two themes: the positive and negative effects of using a notebook computer in class, and different perspectives on the effects of using a notebook computer in class. The positive effects of notebook computer usage were specified as production of lecture notes, performing searches for information, management of learning materials, and effective time management. However, behaviors such as perusing other works not associated with the class were indicated as negative effects. The participants had different perceptions about the effect of notebook computer usage in increasing academic performance, although they were satisfied in their experience with notebook computers in general. These results imply that appropriate methods of technology usage are needed and that the support of an instructor is essential to achieve fully beneficial use of notebook computers in class.

Computers have become an indispensable part of everyday lives in 21st century. This is particularly true in early childhood education; multimedia use in kindergarten has rapidly grown in the last decade. Although ample research had been done on the issues of teachers' role in multimedia settings and selecting quality materials, few studies have been done on the proper environment for multimedia use in early childhood education. In this regard, this research examines the current status of multimedia use-animated illustration films, CD-ROM titles, and internet-in kindergarten. In addition, computer environment in kindergarten is investigated in order to provide guidelines for appropriate facilities and equipments. For smooth integration of computer activities into a school system, computers are located in ordinary classrooms in more than half of kindergarten in Seoul. Computers are used in independent lab settings in the last of the kindergarten in Seoul and there are four different types of lab settings. Among them computer at perimeter style is preferred for the ease of student-teacher, and student-student interactions. The importance of environment for early childhood education cannot be overestimated. It is so critical for early childhood education that the people in this field regard the environment as 'the third teacher' next to parents and teachers. Therefore the multimedia environment should also be considered seriously for the maximum use in early childhood institutions.

This study investigated the viewpoint of teachers on the desirability of computer education in the early childhood classroom. The subjects were 8 kindergarten teachers in Seoul and Kyong'gi Province who used computers in the classroom. Nondirective and open-ended interview methods were used for data collection. Five steps or stages of viewpoints were found: step1-teachers want to have computers in the classroom but have no particular purpose in mind; Step 2-teachers want the children to play with the computers as if it were a toy; Step 3-teachers want to use any programs that are in the computer; Step 4-teachers want to use the computer more purposefully for educational goals; Step 5-teachers want to unify the early childhood curriculum through the multi-media system.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, ′the process of the length of curve being equal to the sum of the vectors when intervals get smaller′ and ′the process of calculating volume of spinning curve by using definite integral.′ Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Also it can help students with solving mathematical problems intuitively. Consequently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the application of definite integral", which exists in mathematical curriculum the second and third grade of high school. When this study is used for students as assisting materials, it is expected the following educational effect. 1. Students will have precise concepts because they can understand what they learn intuitively. 2. Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 3. It is possible to change the teacher-centered instruction into the student-centered instruction. 4. Students will understand the relation between velocity and distance correctly because they can see the process of getting the length of curve by vector through the monitor. For the purpose of increasing the efficiencies and qualities of mathematics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, teachers have to use the CIA program carefully.

In this paper, we design a environment in computers and mathematics education. For this purpose, we study two different points of view about relations between computers and mathematics education. As theoretical background, we also study constructionism and microworld. Next, we introduce functionization as a basic principle for computers and mathematics education. The concept of functionization focuses on the variation of mathematical objects, and it is a basic concept of both mathematics and computer science. We consider the concept of functionization as a paradigm for the research and practice of the computers and mathematics education. We also present the concept of functionization as a principle for designing a computer environment. Finally, we use the concept of functionization to integrate two famous microworlds, LOGO and DGS by introducing such objects as tiles and folding nets. Combining LOGO and DGS, we design a new microworld that can be used under the internet environment. We present tiles and folding nets to introduce how the concept of functionization is used to design a new microworld and to integrate two microworids.
