A mathematics pre-service teacher T analyzed American mathematics textbooks and developed his teaching material for instruction. This study analyzed his thinking processes and results in the view of semiotics. If we regard the textbook as a sign and the unitary conversion that students should learn as an object of the sign, the interpretant of the sign is the pre-service teacher's analysis, which is conducted at the aspects of a subject matter knowledge and student understanding. T interpreted the textbook versatilely in terms of his knowledges and experiences. He developed his teaching materials as diagrams, did the diagrammatic thinking and became to have the hypostatic abstraction. This study is significant because it used semiotics for explaining T's thinking process.

Traditional music education for infants is the most important step of forming human knowledge. Since their rapid development of intelligence and emotion has an educational value not only it improves the human knowledge but also it makes infants understand the unique emotion of Korean people. Under the several circumstances, however, we have no enough contents for traditional music education. Thus, by researching and analyzing the existing educational contents and complementing them properly for multimedia environment as a form of animation, we perform a series of experiments to infants who are attending to the kindergarten with interactive animations which are familiar with infants. Infants become interested in the contents and after the lesson of the short bamboo flute content, they show the clear improvements for the playing on a musical instrument. This proves that the Korean music educational content realized with animation can be an alternative plan to improve the educational effect by causing enjoyment and interest of infants.

Learning the principles of perception belongs to both the psychology and art field. However, people define that an art education is an activity of expression, so an activity of an art appreciation is either downsized or hardly proceeded in an art class. Therefore, the art appreciation educational program that gives a motivation to appreciate the work of art and to minimize a burden towards the activity of an art appreciation is needed. This paper proposes an educational program that includes activities to appreciate the work of art using the principles of perception and to create personal portfolios. Also, we analyze the eye movement of the paintings according to the principles of perception. Finally, proposes the art appreciation education program based on Feldman's critique method. In addition, we illustrate the example of the proposed art appreciation educational program with the analyzed paintings from section III.

In Korea, previous survey in science education mainly dealt with Quantitative variables. Qualitative ethnographic observation can bring deeper understanding of the context of school lesson and it's feature. The purpose of this study was to develop qualitative understanding about the learning experiences provided in middle school and students' responses to them through observation and interview and to investigate it from a constructivist perspective. Six lessons of the 9th grade were observed and recorded on the video tape. The topics of the lessons were potential energy, kinetic energy and conservation of mechanical energy. We had also unstructured interview with the teacher and three groups of students. The teacher's deductive explanation starting from scientific definition and quantitative problem solving using formula were the main features of the classroom lectures. The video - watching lesson was taking the role of a break rather than being seen as a useful tool for science learning and teaching by both students and the teacher. The teacher's perception about the lab experiment was not supported by the responses from the students. The teacher and students preferred problem-book to textbook for their teaching and learning. From a constructivist's perspective, however the teacher seemed to have intention of introducing daily life context, he couldn't unfold it to main context of the lessons. Students were so accustomed to passive learning that they did not express directly their complaint about their learning and did not participate in planing and controling their learning. The teacher and the students believed the scientific knowledge came from an exact experiment. There was a cooperation to seek right answer rather than a social process of making sense of knowledge. In conclusion, the observed science lessons of a middle school showed typical cross section of teacher - centered, passive learning environment, which is far from constructivist perspective.

Since the 7th National Curriculum was established, ICT has emerged as an indispensable tool for teaching a variety of subjects in K-12 education systems. This paper develops the model for explaining the factors affecting students' satisfaction level in using web contents for science class. Based on data collected from a questionnaire survey from the students who evaluated the web sites providing the information related to the science subject, the structural equation model is presented. From this model, a following conclusion is provided : credibility and understandability/motivation are the most important factors affecting the level of satisfaction, but the presentation method, the screen design as well as contents itself has indirect impact on user satisfaction through understandability/motivation. Other interesting results are also provided. This result might provide the useful guidelines for designing the web-contents for science class in high school.
