This study analyzed the items for the Home Economics teacher selection test, which were carried out through the school year 2002 to 2010, based on Pedagogical Content Knowledge in Home Economics Education (H-PCK). Two frameworks were used: (1) H-PCK matrix transformed from the Content Knowledge in Home Economics Education (H-CK) and the Pedagogical Knowledge; (2) Five components of H-PCK. The results of this study were as follows: (1) The test items were classified into H-CK items and H-PCK items from the H-PCK matrix analysis. (2) While the number of items on knowledge of teaching strategies was the highest, no item on knowledge of understanding students was identified. Since the test can be considered as Measurement-Driven Instruction, it will have backward influences on the teacher education program in universities. Thus, if promising and capable new Home Economics teachers are to be recruited, the test items should include all the components of H-PCK.

Objective: The purpose of the study was to explore early childhood teachers' content knowledge and knowledge level on unification education through an analysis of a concept map (Novak & Gowin, 1984). Methods: The subjects, including 65 early childhood teachers in a metropolitan area, were asked to draw concept maps illustrating their understanding of unification education for young children. The collected concept maps were analyzed using the methods utilized by Novak and Gowin (1984) as well as You and Kim (2018). Results: In terms of early childhood teachers' content knowledge, 282 superordinate concepts and 1,766 subordinate concepts were shown. The 282 superordinate concepts were categorized into 7 representative superordinate concepts: understanding of North Korean, understanding of separation/unification, identification as Korean citizen, unification policy, relationship between South Korea & North Korea, educational activities, connection with home and society. In terms of early childhood teachers' knowledge level, the numbers of subordinate concepts and hierarchical level were shown to be varied according to the 7 representative superordinate concepts. Conclusion/Implications: Discussions were included to support and enhance early childhood teachers' content knowledge on unification education for young children through the development of comprehensive programs and teacher education.

This study has investigated the factors that make a science teacher effective by analyzing students' perception of teacher knowledge required in enhancing their science learning. The basic components of teacher knowledge identified by previous researchers have been confirmed through Exploratory Factor Analysis (EFA). Based on the findings of the EFA, the questionnaire has been further analyzed using Confirmatory Factor Analysis (CFA) by means of Structural Equation Modeling (SEM). In addition, the differences in students' perception on the identified factors of effectiveness have also been analyzed in terms of gender and achievement level. The findings of the EFA showed that five factors of science teacher effectiveness were identified; namely, substantive knowledge, syntactic knowledge, knowledge of students' understandings, knowledge of instructional strategies, and knowledge of assessment. These five components have been divided into two categories of teacher knowledge, SMK and PCK. What we found from the CFA was the respective high correlation between substantive and syntactic knowledge, knowledge of students' understanding and instructional strategies and the low correlation between substantive knowledge and knowledge of instructional strategies. Students perceived substantive knowledge as the most effective factor, knowledge of assessment as the least effective factor. Also, there have been considerable differences in students' perception by gender and achievement level. We proposed, based on the findings, that SMK and PCK need to be integrated into a coherent manner for the effective science teaching practice. This study provides some implications for science teacher professional development and the improvement of science teacher preparation program.

The purpose of this study is to uncover weaknesses in the constructivism in mathematics education and to search for ways to complement these deficiencies. We contemplate the relationship between the capability of construction and the performance of it, with the view of the 'Twofold-Structure of Mind.' From this, it is claimed that the construction of mathematical knowledge should be to experience and reveal the upper layer of Mind, the Reality. Based on the examination on the conflict and relation between the structuralism and the constructivism, with reference to the 'theory of principle' and the 'theory of material force' in Neo-Confucianist theory, it is asserted that the construction of mathematical knowledge must be the construction of the structure of mathematical knowledge. To comprehend the processes involved in the construction of the structure of mathematical knowledge, the epistemology of Michael Polanyi is studied. And also, the theory of mathematization, the historico-genetic principle, and the theory on the levels of mathematical thinking are reinterpreted. Finally, on the basis of the theory of twofold-structure, the roles and attitudes of teachers and students are discussed.

This study investigated the level of academic passion for elementary school teachers' science pedagogical content knowledge (PCK) and examined the factors that influence the passion. To this end, 161 elementary school teachers in Seoul were selected, and academic passion tests were then administered to evaluate their academic passion for science subject matter knowledge and science pedagogical knowledge. Individual in-depth interviews were also conducted with some of the participating teachers. The results revealed that 'importance' and 'harmonious passion' for learning science subject matter knowledge and science pedagogical knowledge were found at a high level. However, 'time/energy investment' and 'obsessive passion' for learning the knowledge were slightly higher or lower than normal. The 'like' for learning science subject matter knowledge was relatively high, but the 'like' for learning science pedagogical knowledge was slightly higher than normal. The differences in academic passion for science subject matter knowledge and science pedagogical knowledge were greater according to advanced major at undergraduate than teaching career. The teachers evenly selected some factors that influenced their academic passion for science subject matter knowledge and science pedagogical knowledge. These identified characteristics included 'individual interest', 'high school track', 'experience in advanced major at undergraduate', 'experience in science-related graduate school', 'experience teaching science in elementary school', 'experience teaching science at the gifted education institute', 'experience in charge of science subject teacher', 'experience in science-related teacher training', 'experience in developing science-related teaching and learning materials', 'experience in charge of science or science-gifted related work', and 'experience in a science-related teacher community'. However, a slight difference was noted in the selection ratio depending on advanced major at undergraduate. Based on these results, the practical implications for improving their academic passion for science PCK are suggested.

This study investigated the perceptions of beginning teachers about teacher knowledge. Reflections and improvement of their class knowledge have been perceived as the most important factors by beginning teachers. In terms of utilization of actual classes, teacher knowledge, mathematical concepts and correlations such as connection linked to class contents and hierarchy have been used the most. Among the needed teachers knowledge, knowledge of student understanding and mathematics content knowledge was the most essential knowledge that could be mainly formed through classroom experience and teacher training program. On the other hand, knowledge about technology and assessment was not necessary or useful factor for beginning teachers. To facilitate formation of beginning teachers' knowledge, teacher introductory program, mentoring program, interactive relationship with teacher education institutes, curriculum improvement for teacher education institute and the development and dissemination of various teachers training program would be required.

TPACK (Technological Pedagogical Content Knowledge) adds the technological knowledge to PCK (Shulman 1986), completing the combination of three kinds of knowledge, i.e. teacher's content knowledge (CK), pedagogical knowledge (PK), and technological knowledge (TK). In this study, I seek to design methodological ways to improve TPACK for preservice mathematics teachers by developing and analyzing team project-based classes with technology in a class of the first semester 2009 in a teacher's college in Seoul, South Korea. The goal of the team project is to design classes to teach mathematics with technology by selecting technology tools suitable for specific mathematical concepts or mathematics sections. In the early stage of the class in the college, the confidence levels among the preservice mathematics teachers were relatively low but increased in the final stage their mathematics teaching efficacy up to from 3.88 to 4.50. Also, the pre service mathematics teachers answered the team project was helpful or very helpful in developing TPACK; this result proves that lectures with technology which based on team project are excellent tools for the teacher to design classes with technology confidently. Considering the teacher's TPACK is one of the abilities to achieve the goals required in the information technology era, the preservice mathematics teachers are asked to plan and develop the lectures with technology, rather than just taught to know how to use technology tools or adapt to specific cases. Finally, we see that national-wide discussion and research are necessary to prepare customized standards and implementable plans for TPACK in South Korea.

PCK(pedagogical content knowledge) has been frequently discussed in the field of subject matter education as well as education in general. Considering the fact that PCK characterizes teacher professionalism, and the distinction of mathematics education from neighboring disciplines, PCK is one of the core concepts in the discourse of mathematics education. This study focused on KCS(knowledge of content and students) among the areas of PCK. The purpose of this study to investigate the KCS of pre-service teachers attending a private university located in Seoul. An in-depth interview with 30 pre-service teachers was conducted in a semi-structured manner, using four questions dealing with common student errors, students' understanding of content, and student developmental sequences. The pre-service teachers gave mathematical answers while in others they gave priority to pedagogical considerations. The implication drawn from the interview data is that the teacher training program should fully reflect the complexity of mathematical concepts which appeared in school mathematics over several grade levels and content areas.

The purpose of this study was to examine early childhood teachers' knowledge and the level of their knowledge on the contents of early childhood nutrition education. The subjects were 105 early childhood teachers and they were asked to draw a concept map. The number, characteristics and density of superordinate concepts on the contents of early childhood nutrition education were analyzed. The results were as follows: Firstly, the most frequent superordinate concept was dietary habits. Secondly, food culture was the highest average of the number of subordinate concepts. In a hierarchy, food culture was also the highest score. In specificity scores, food was the highest score. And the density ranged from 0.33 to 3.60. In conclusion, the teachers' knowledge structure on early childhood nutrition education could be regarded as parallel, not well-integrated, rather than hierarchical or well-organized. A variety of nutrition education and customized teacher training should be provided for early childhood teachers to offer early childhood nutrition education.
