The purpose of this study is to analyze middle school students' learning characteristics they showed on the inquiry-based learning process of circumcenter using various teaching tools, and then to identify the effects of using teaching tools in the middle school students' learning process of circumcenter. For this purpose, we developed teaching materials for inquiry-based learning of circumcenter using textbook, origami, ruler and compass, GeoGebra and sand experiment. Then we applied them on the learning process of circumcenter for five groups of middle school students. From the analyzing of audio/video materials and documents which are collected from the process of participants' inquiry-based learning of circumcenter, we identified the following results. First, inquiry-based learning of circumcenter using various teaching tools promoted mathematical discourses among participants of this study. For example, they conjectured mathematical properties or justified their opinions after manipulated teaching tools in the process of learning circumcenter. Second, inquiry-based learning of circumcenter using various teaching tools promoted participants' divergent thinking. They tried many inquiry methods to find new mathematical properties relate to circumcenter. For example, they tried many inquiry methods to know whether there is unique circle containing four vertices of given quadrangles. Third, we found several didactic implications relate to inquiry-based learning of circumcenter using various teaching tools which are due to characteristics of teaching tools themselves. Participants showed several misconceptions about mathematical properties during they participated inquiry-based activity for learning of circumcenter using various teaching tools. We identified their misconceptions were not due to any other variables containing their learning characteristics but to characteristics of teaching tools.

The purpose of this study is to investigate what English teachers think about what and how to teach culture, as a way of helping students build relevant background knowledge and enhance their motivation in learning English. A total of 300 teachers completed a self-report questionnaire in four areas: (i) their understanding and liking of English-spoken countries, (ii) their use of materials and tools for teaching culture, (iii) their consciousness of teaching culture, and (iv) their needs for culture learning in the teacher-training program. The results show that (i) they think American culture is dominant in EFL but they are much interested in British culture; (ii) they rely on internet most for their cultural experience while they think students get much of the cultural information from textbooks; (iii) they are very much conscious of the importance of teaching culture for improving students' English proficiency; (iv) they want to learn in the teacher training program more about cultural practice, which can be subsumed under the so called 'small c'. The findings suggest that (i) textbooks need to include contents to promote students' cultural awareness and foster intercultural competence, (ii) teachers should use authentic materials with appropriate adaptation, and (iii) a teacher training program should cover a wide range of contents and skills for teaching culture.

Problem-centered learning has many implications on teaching and learning mathematics. Students devise their solutions to solve problems and participate in the discussion with teacher and other students to share and justify their solution during the problem-centered learning. Therefore, we purposed to provide problem-centered loaming materials to be able to use in teaching and loaming the 7th mathematics curriculum in this study. First, we reviewed the 7th curriculum and its textbooks to know what and how students learn and suggested the problem-centered learning as a teaching method to perform the 7th curriculum. Next, we developed the problem-centered loaming materials for 6th grade in elementary school and taught students with these materials to amend errors. Finally, we developed evaluation criteria to evaluate students while they teamed mathematics in the problem-centered learning.

Science has developed along with human society and history. In today's society ruled by pluralism, an educational approach using the historical materials which represent their own cultures will make science education more effective. The purpose of this study was to search for the meaning of science education related with a history of science, and to suggest the possibility for science education based on Korean history of science. The conclusions of this study is below: (1) The history of science is useful to teaching science in K-12 setting. That is because it was helpful to make a scientific concept and to invite student's interest about learning science. Moreover, it was most suitable to teach the nature of science as well as the relation between science and society. (2) A model which consists of 15 types of science education materials using Korean history was suggested. This model plays a potential role as a R&D framework of developing teaching & learning materials based on the history of Korean Science.

The curriculum especially in Korea plays a crucial role in developing instructional materials. It serves as a criterion for selecting and organizing content of teaching materials. Therefore, the validity of a curriculum can be justified through testing effectiveness of an instructional material developed in accordance with the curriculum. This paper presents an instructional method and material developed based on the current tendency of educational thoughts that emphasize STS and students - centered teaching strategies in science education. The instructional material was organized around the concept and its subconcept of "nutrition" as presented in the high school biology textbooks now in use in the nation as well as in a few world-wide countries. It was also organized by the use of biological events and phenomena which high school students in rural areas can easily encounter through their everyday lives. The significant findings in this study are : ${\circ}$ The achievement levels in experimental groups were higher than one in controlled groups. ${\circ}$ The students as well as the teachers involved in this study showed positive attitude toward the instructional method developed in the process of this study. ${\circ}$ The greater part of the students among the controlled groups hoped that biology would be taught by this kind of teaching procedure and materials.

This study analyzes the characteristics of elementary math gifted classes through the development and application of teaching and learning materials. We used the guided reinvention methods including quasi-experiential perspectives. To this end, the applicability of Lakatos' quasi-empirical mathematical philosophy in elementary mathematics was examined, and the criteria for the development of teaching and learning materials for gifted students were presented, and then this study was conducted in this theoretical background. The subjects of the study were 21 elementary students at P University's Institute of Science and Gifted Education, and non-face-to-face real-time classes were conducted. Classes were divided into introduction, deployment1, deployment2, organization stages, and in each stage, small group cooperative learning was conducted based on group activities, and in this process, the characteristics of elementary mathematics gifted were analyzed. As a result of the study, elementary mathematics gifted students did not clearly present the essence of justification in the addition algorithm of fractions, but presented various interpretations of 'wrong' mathematics. They also showed their ingenuity in the process of spontaneously developing 'wrong' mathematics. On the other hand, by taking interest in new mathematics starting from 'wrong' mathematics, negative perceptions about it could be improved positively. It is expected that the development of teaching and learning materials dealing with various and original topics for the gifted students in elementary school will proceed through follow-up research.
