Computers are played an important tole of knowledge-information society in 21C. Computer education have made successful progresses since the 7th curricula have one class of ICT per week. However, public schools have instructed computer literacy education teaching only how to use application software. To give useful knowledges students could use for several decades, we need to have them to concentrate on education to information logical thinking power rather than simple manipulation of application softwares. However, teachers don't understand well about the "Understanding of Information Processing". In this paper, we carried out a survey that how much teachers understand about the information processing comprehension among the information and communication technology guide. We also state problems and propose improvement plan.

This study investigated what kind of informal knowledge is emergent and what role informal knowledge play in process of solving 2-digit by 2-digit multiplication task. The data come from 4 times interviews with a 3th grade student who had not yet received regular school education regarding 2-digit by 2-digit multiplication. And the data involves the student's activity paper, the characteristics of action and the clue of thinking process. Findings from these interviews clarify the child's informal knowledge to modeling strategy, doubling strategy, distributive property, associative property. The child formed informal knowledge to justify and modify her conjecture of the algorithm.

This article studies the understanding of acid and base concepts of the 3rd-grade students in middle school. An effective teaching strategy for improving their acid and base concepts was designed by considering students' prior knowledge using Lawson's learning cycle method. The control group was adapted by the traditional teaching strategy which isn't considering students' prior knowledge. After the class, understanding of acid and base concepts of treatment group was significantly higher than that of control group. But the level of students' understanding of strong acid, weak acid strong base and the strength of acid in aqueous solution was low even after the class of two groups. This indicates indirectly that the microscopic views of acid and base concepts in aqueous solution are not easy to learn for these students. For the four categories of acid and base concepts, students' responses were reviewed carefully and classified into scientific conceptions and misconceptions. These results will be useful for developing an effective teaching strategy of acid and base concepts.

SENKs (Students who Emigrated from North Korea to South Korea) are exposed to the general problem of Su-Po-Ja(mathematics give-uppers) as well as their own difficulty in learning mathematics. In this study, we conducted the FGI (focus group interview) in order to examine the recognition on mathematics teaching and learning in South Korea with 6 SENKs and 3 teachers who teach the SENKs. As a result, it was found that SENKs' had difficulties in understanding math because of the differences in math terminology used in South and that in North Korea, the unfamiliar problem situation used in math lesson, and the shortage of time for solving math problem. And the teachers reported that they had difficulties in teaching great deal of basic math, SENKs' weak will to learn math, and SENKs' lack of understanding about problem situation because of the inexperience about culture and society in South Korea.

The purpose of this study is to investigate the proportional reasoning of middle school students during the process of expressing and interpreting the graphs. We collected data from a teaching experiment with four 7th grade students who participated in 23 teaching episodes. For this study, the differences between student A and student B-who joined theteaching experiment from the $1^{st}$ teaching episode through the $8^{th}$ -in understanding graphs are compared and the reason for their differences are discussed. The results showed different proportional solving strategies between the two students, which revealed in the course of adjusting values of two given variables to seek new values; student B, due to a limited ability for proportional reasoning, had difficulty in constructing graphs for given situations and interpreting given graphs.

오늘날 세계는 일반국민과 과학기술의 상호관계에 대해 두 가지 큰 논쟁에 빠져있다. 하나는 국민의 과학기술에 대한 공동체 유대감을 어떻게 형성하느냐하는 것과, 또 다른 하나는 과학기술에 대한 일반국민의 이해 수준을 어떻게 측정하느냐에 대한 것이다. 다시 말해서 이제 과학계는 금연캠페인이나 환경캠페인의 성공처럼, 과학기술 지식을 활용하는 데 국민의 참여를 불러오도록 적극적으로 나서야 하며, 그것을 통해 과학기술에 대한 국민의 이해를 높일 수 있다는 주장이다. 즉 일반국민의 과학기술에 대한 공동체 유대감을 높이는 길은 그들의 관심에 근거할 때 가능하며, 그런 과정에서 과학기술에 대한 이해도 높아진다. 예컨대, 지금 우리 국민의 최대 관심사는 급성호흡기장애로 죽음까지 불러오는‘사스 (SARS)’확산과 북한의‘핵무기’소유이다. 그렇다면, 과학기술계와 국가가 전적으로 나서서 그 문제들을 해결하는 모습을 보일 때, 과학기술에 대한 국민의 공동체 유대감이 형성될 수 있고, 나아가 병리학과 핵물리학 자체에 대한 일반국민의 이해도 증진될 수 있다. 본 연구는 이러한 맥락에서, 과학영재 학생들의 과학기술에 대한 이해도를 알아보기 위해 요즈음 국제 사회적으로 커다란 이슈가 되고 있는 북한 핵문제에 대해 과학영재들은 어떤 생각을 갖고 있으며, 어느 정도 이해하고 있는지를 설문조사 하였으며, 이를 남학생과 여학생을 구분하여 분석하였다. 설문에 응답한 학생들은 모두 85명으로 공주대학교 과학영재교육원 영재교육 프로그램에 참여하고 있다.

The study aims to compare between two lectures of elementary mathematics education in United States and Korea based on the Ball et al.'s classification of mathematical knowledge for teaching. The lecturers are a professor of University in United States and me. In both lectures, subjects and contents of lectures are much similar but there are many different things. And the differences are mainly due to the area of pedagogical content knowledge, especially either knowledge of content and students or knowledge of content and teaching. Also the different courses of both universities are one of important causes of the differences. The study will be able to contribute to the studies on the improvement of our course, elementary mathematics education.

Inspired by the idea that classroom instruction proceeds through knowledge-sharing, this study examined different modes of knowledge-sharing that were realized in discursive practices in Korean secondary science classrooms. Data came from 9 science teachers. An interpretative strategy was employed to analyze the video-recording of the teachers' own science classrooms and transcriptions. The results showed four different modes of knowledge-sharing, including 'retrieving subject matter knowledge', 'reformulating subject matter knowledge', 'expansion and elaboration of understanding', and 'negotiation of meaning'. It was also revealed that there was a tie between an active mode of knowledge-sharing and scaffolding: the former allowed students to take active roles in discourses and the latter was one of the desired patterns of classroom interaction. It was suggested that further studies should be conducted to understand science instruction from more varied perspectives and to examine and utilize the detailed features of desired classroom practices like scaffolding.

This study is to examine how activities using local multi -cultural resources and world geography lessons using the CCAP(Cross-Cultural Awareness Programme) affect students' multi-cultural understanding. Activities using local multi-cultural resources were carried by visiting in an alien worker community, volunteering in multicultural center, attending on UNESCO ASP(Associated School Program), and making radio broadcasting program associated with 'SCN FM' which is a local broadcasting station on the weekend. And world geography lessons using the CCAP were conducted with 5 classes including orientation by inviting foreign instructors from that place after reconstructing the Southeast and South Asia unit of the countries such as Pakistan, the Philippines, Myanmar and Cambodia. According to twice questionnaire survey conducted before and after activities using local multi-cultural resources and world geography lessons using the CCAP, it appeared that students had familiarity more than before through direct meeting with foreigners inside and outside classroom, and understood and respected other cultures by acquiring contextual regional knowledge. In the end, multi-cultural activities and world geography lessons using the CCAP contributed to students' global citizenship, which overcame prejudice toward third world cultures. Like that, if world geography classes provide continually students with opportunities to experience directly diverse cultures inside and outside classroom, world geography overcome negative image that it transmit decontextual regional knowledge and is regarded as the subject that is very fit for nurturing global citizenship based on contextual knowledge, consideration and tolerance needed in global and multi-cultural society.
