TPCK is the knowledge of intersection in mathematics, technology, and pedagogy. This study investigated a teacher's change of his TPCK. He participated in the professional development program which was designed to develop mathematics teachers' TPCK. The professional development program was based on using spreadsheets in teaching mathematics. The researcher suggests a consideration for the integration of technology in mathematics education and mathematics teacher education. The program consisted of a four week summer professional development program and three actual mathematics classroom teaching. Ten teachers took part in the program. One teacher who changed his TPCK most was selected to investigate what made it change most. Following teaching practice was the most influential factor in changing his TPCK.

This study investigated the influence of paired think-aloud problem solving on interactions among the pedagogical content knowledge (PCK) components considered in the processes of making written test items by pre-service chemistry teachers. The processes of making written test items using paired think-aloud problem solving in four small groups consisting of two pre-service chemistry teachers were recorded and transcribed. The analysis of the results revealed that the 'assessment in science education' of the five PCK components, regardless of the roles (solver or listener), was most frequently used in making written test items. 'Subject matter knowledge' and 'students' were also frequently used although less than the previous component. However, 'curriculum for science education' and 'instructional strategies and instruction for science education' was a little used. In the aspects of integration, the integrations between two or three components of various types were frequently found. The integrations among four or five components were also slightly found. However, the integrations of 'curriculum for science education' with the other components were less frequently found. The integrations of 'instructional strategies and instruction for science education' with other components were hardly found. The usefulness, limitations, and effective use of paired think-aloud problem solving as a strategy improving competency to make written test items and the PCK of pre-service teachers were discussed on the basis of the results.

The purposes of this study were to examine what kinds of educational activities were carried out during the practice teaching based on CoRe and to identify the role of CoRe and its influence on the development of expertise of student teachers. This study was performed as qualitative case study. The subjects of this study were one practice supervisor teacher and two student teachers. Data were collected through recording CoRe discussion process, student teachers' instructional scene, and semi-constructed interview, and analyzed by an inductive method. Student teachers noticed their own misconceptions, and clarified the concepts based on CoRe during the discussion with supervisor teacher. They also supplemented their lack of knowledge and made up new strategies through the process of sharing their ideas. During the discussion, the supervisor teacher conveyed his teaching experience based on his own orientations toward science teaching. In this course, CoRe plays roles as follows. Firstly, CoRe played a role as guiding supervisor teacher's coaching process. Secondly, CoRe helped for the supervisor teacher to recognize their own PCK. Thirdly, CoRe served as a tool of helping their communication. In turn CoRe proved to be a useful frame for teaching student teachers during practice teaching. Student teachers were provided with a useful framework for preparing lessons by developing CoRe for the topic they teach. Developing CoRe with supervisor teacher at the planning stage of lessons enhenced student-teachers' subject matter knowledge and their PCK including knowledge of science curricula and knowledge of student's understanding of science. Also student teachers understood the components of PCK and experienced the positive understanding toward students, teaching activities, and themselves as a science teacher.

This study has attempted to analyze the achievement standards in the 2015 revised curriculum, based on the revision of Bloom's Taxonomy and aims to identify the knowledge and required competencies in the fourth industrial era. The results of this study are as follows: First, the knowledge dimensions was the highest 'metacognitive knowledge' in middle school, while 'factual knowledge' was the highest in high school, and 'knowledge of specific details and elements' was the highest subtype of all of the knowledge dimensions. The dimensions of the cognitive process, such as the terms 'apply' and 'analyze' in middle school, as 'understand' and 'evaluate' in high school have been treated inattentively. Second, the knowledge dimension and the cognitive process dimension according to key concepts display the metacognitive knowledge and 'understand' in development, the conceptual knowledge and 'understand' in relationship. While the 'metacognitive knowledge' and 'apply' in life culture, the 'procedural knowledge' and 'evaluate' in safety, the 'factual knowledge' and 'apply' in management and the 'metacognitive knowledge' and 'understand' in life design were extremely high. Third, the verbs used in the achievement standards displayed as 'explore', 'understand', 'analyze', 'practice', 'suggest', 'recognize' and 'evaluate'. Since the statement of the action verb is the very basis for determining the performance process, specific competencies may be achieved by reflecting on the actual achievement standards. These standards should provide us with a effective cognitive process for to understand a learner's performance skills and support the direction of the education required, through a strategy that refines the connection between content elements and functions and develop their competences for the future.

As the spatial analysis paradigm was established in the discipline during the 1960s, the regional geography became regrded as a nonscientific enterprise. However, school geography has remained an old fashioned regional paradigm. Since then, regional framework which characterized geography curricula in education has been attacked and replaced by more scientific and systematic content. But recently, globalization and localization has rapidly transformed the everyday life of ordinary people. This social change requires regional awareness in school. The purpose of this study is to find relevant learning theories for geography in deucation and to suggest principles of constructing content for regional geography. We must transform the logic of regional concepts into educational content with reference to the learning process. We must examine various propositions for the leaming process. According to the Atomic view of knowledge, the learning process is cumulative, but this can't be applied to sophisticated knowledge. In the Organic view, the learning process is regarded as gradual differentiation. But the learning process is reciprocal, and socially constructed. Applied to geography in education, this view regard "meaningful learning" as social interaction between student's private geographies and content based on public (or academic) geographies.

Geological information on the Korean Peninsula plays a significant role in science education because it provides a basic knowledge foundation for public use and creates an opportunity to learn about the nature of geology as a historical science. In particular, the Mesozoic Era, when the Korean Peninsula experienced a high degree of tectonic activity, is a pivotal period for understanding the geological history of the Korean Peninsula. This study aimed to analyze whether content regarding the geology of the Mesozoic Era are reliably and consistently presented in the 'Geology of the Korean Peninsula' section of Earth Science II textbooks based on the 2015 revised curriculum. Four textbooks for Earth Science II were analyzed, focusing on the sedimentary strata, tectonic movement, and granites of the Mesozoic Era. The analysis items were terms, periods, and rock distribution areas. The consistency within and among textbooks and of textbooks and scientific knowledge was analyzed for each analysis item. Various inconsistencies were found regarding the geological terms, periods, and rock distribution areas of the Mesozoic Era, and suggestions for its improvement were discussed based on these inconsistencies. It is essential to develop educational materials that are consistent with the latest scientific knowledge through collaboration between the scientific and educational communities.
