The purpose of this study is to analyze some Korean elementary pre-service teachers' Mathematical Knowledge for Teaching(MKT). For this purpose, we selected the MKT items on number and operations which were adapted for Korean in-service teachers by Lee(2011). The survey consisting of those items was administered to 76 Korean elementary pre-service teachers at Teachers College, J University. The results are the following: First, the respondents, elementary pre-service teachers, showed that the preference for the MKT items was very affirmative, but the percentages of correct answers to the MKT items weren't generally high. Second, the preference for the instructional consultation by experienced teachers was very affirmative. Third, the percentages of correct answers to KCS, SCK, CCK and KCT were 70.13%, 55.71%, 43.87% and 29.27%, respectively. Fourth, the percentages of correct answers to type 5, 6, and 7 were more than 60%, but those of correct answers to type 1, 2, 3, 4, and 8 were less than 60%. This means we need to strengthen type 1, 2, 3, 4, and 8 in education of elementary mathematics subject at Teachers College of J University.

In order to explore the influences of coteaching through mentoring upon the teaching professionalism of beginning science-gifted education teachers, this case study deeply investigated the change processes in the aspects of pedagogical content knowledge (PCK). Two beginning teachers planned, performed and reflected together their science instructions for science-gifted students in secondary school during four 3-hour classes. Since the second instruction, pre-, during-, and post-mentoring were conducted, we collected various data related to teachers' planning processes, videotaped all coteaching science classes, and wrote field notes. We also recorded in-depth interviews with the teachers and the whole process of mentoring. All the data were analyzed by using the constant comparative method. The results of the analyses indicated that coteaching through mentoring positively changed the teachers' PCK. Above all, we found that coteaching and mentoring strategies generated a significant synergy effect through a mutually complementary relationship. The teachers developed deep practical knowledge about the enrichment curriculum, which placed more emphasis on developing cognitive and/or affective characteristics of science-gifted students. The teachers also improved their knowledge about the characteristics of science-gifted students and the instructional strategies appropriate for developing them. Moreover, practical knowledge about assessment domains and methods used in science-gifted education were improved. Knowledge on science content necessary for effective inquiry instruction was also improved.

수학교육 개혁에서 강조되고 있는 교실 문화의 변화는 교사가 그 개혁 방향을 이해하고 자신들이 지향하는 가치와 우선 순위를 수업에 어떻게 적용하느냐에 달려 있다고 볼 수 있다. 이와 관련하여, 본 논문에서는 문헌을 통하여 교수 방법에 영향을 미치는 교사 변인 (교사의 학습 및 교수 경험, 지식, 신념, 개별인성특징) 및 사회문화적 변인 (문화적 ${\cdot}$ 교육적 규준, 교육과정 개발과 운영, 교사교육, 전문적 모델과 교사공동체)을 찾아내고 이를 기초로 하여 수학 교사의 교수 방법에 영향을 미치는 요소를 질적으로 분석하기 위한 구체적인 개발면담 질문을 제시한다.

교사 교육기관에서 교육을 받고 있는 예비 수학교사들의 교수-학습에 대한 신념은 주로 초, 중, 고등학교를 다니면서 수학 교사와의 상호작용과 긍정적 혹은 부정적인 경험에 의해서 형성되어져 있다. 이러한 신념은 결국 사범대학에서의 교육을 받으면서 지식의 습득 과정에 영향을 미치게 된다. 따라서 예비수학교사들이 가지고 있는 수학의 교수-학습에 대한 신념을 조사하는 것은 이들이 기존에 가지고 있는 신념에 대한 반성의 기회를 제공하게 되어 바람직한 신념형성 및 장차 교사가 되었을 때 수학교실에서의 교수-학습의 새로운 전환에 도움이 될 것이다. 그리고 이들의 신념을 조사, 연구하는 것은 현재 수학과 교사 교육기관에서 이루어지고 있는 교수와 학습에 대한 질을 개선하는데 도움이 될 것이다.

The purpose of this study is to explore the main characteristics regarding of implicating competence-based curriculum in Finland's home economics curriculum by analyzing curriculum documents and related literature. The research findings are categorized into four main characteristics. First, home economics in Finland belongs to the 7-9 grades. The key content areas are composed of 'food knowledge & skills and food culture', 'housing & living together' and 'consumer & financial skills' at an integrated approach. Secondly, the subject competences of home economics are not presented; however, the general objectives of transversal competences are defined in Finland's curriculum document. Transversal competences describe the aspects of the objectives that are emphasized in grades 7-9 and strengthens the connectivity with each subject. Thirdly, the objectives of home economics included in the instructions in Finland consist of a content system that links learning skills, content areas, and transversal competences. Both learning skills as a role of subject competences and content areas as objectives support teachers who restructure an curriculum. Fourth, in terms of achieving subject objectives, the assessment criteria in Finland home economics is to evaluate the achievement of good knowledge and skills through actual performance. Based on the research findings, the main features of the revised curriculum in Finland include encouragement of flexibility in education systems and learner's uniqueness in schools. If the implementation of subject competences in home economics is to be strengthened, it is necessary to intergrate the knowledge and competence, require a curriculum system for implements' subject competence, carryout assessment as learning to learn, and facilitate school community and teacher community for deeper co-operation.

In this study, an operational analysis in the context of linear equations is presented. For the analysis, several second-order models concerning students' whole number knowledge and fraction knowledge based on teaching experiment methodology were employed, in addition to our first-order analysis. This ontogenetic analysis begins with students' Explicitly Nested number Sequence (ENS) and proceeds on through various forms of linear equations. This study shows that even in the same representational forms of linear equations, the mathematical knowledge necessary for solving those equations might be different based on the type of coefficients and constants the equation consists of. Therefore, the pedagogical implications are that teachers should be able to differentiate between different types of linear equation problems and propose them appropriately to students by matching the required mathematical knowledge to the students' potential constructs.
