The purpose of this study was to analyse the belief about mathematics teaching of elementary preservice teachers and mathematics teachers. This study involved 100 respondents from the preservice teachers and 114 respondents from the mathematics teachers. The instruments used in this study consist 15 items of mathematical knowledges and 19 items of mathematical activities. The finding showed that preservice teachers emphasized the conceptual knowledge, whereas mathematics teachers emphasized the procedural knowledge in the mathematical knowledges. And preservice teachers emphasized the knowledge representation, knowledge generation, knowledge deliberation, knowledge communication, whereas mathematics teachers emphasized the use of knowledge(syntax) in the mathematical activities. Finally, even though two groups showed the significant difference in some items, preservice teachers and mathematics teachers emphasized the various mathematical knowledges and mathematical activities.

The purpose of this study is to address the teachers' knowledge bases for effective mathematics teaching and especially to provide the various definitions and the structures of mathematics knowledge which is the most important one of the knowledge bases. The conceptual understanding about teachers' knowledge bases for effective mathematics teaching and the structure of mathematics knowledge may be used in evaluating effective mathematics teaching and teachers as well as in developing a new conceptual framework for the structure of mathematical knowledge.

The purpose of this study is to explore ways for students to connect conceptual and procedural knowledge in mathematical modeling lessons. Accordingly, we selected the greatest common divisor among the learning contents in which elementary school students have difficulties connecting conceptual and procedural knowledge. A mathematical modeling lesson was designed and implemented to solve problems related to the greatest common divisor while connecting conceptual and procedural knowledge. As a result of the analysis, it was found that the mathematical modeling lesson had positive effects on students solving problems by connecting conceptual and procedural knowledge. In addition, through actual class application, a teaching and learning plan was derived to meaningfully connect conceptual and procedural knowledge in mathematical modeling lessons.

본고는 수학적 창의성과 관련한 논문으로 이를 창의적인 사람, 창의적인 산출물, 창의적인 과정이란 일반 창의성 연구자들이 연구하고 있는 분야로부터 유추적으로 논의를 시도하였다. 이런 접근으로부터, 얻을 수 있는 몇 가지 가정들은 다음과 같은 것이 있다. 첫 번째, 일반 보통아들을 대상으로 하는 공교육에서도 창의성 교육을 할 수 있으며, 이는 수학교과에도 적합한 진술이다. 두 번째, 현상학적 입장으로 부터 학교에서 교수${\cdot}$ 학습되고 있는 학교수학이 학생들 입장에서 보면 학습해야 할 필요가 있는 적절하고 새로운 지식이란 점을 공고히 해 주었다. 또한, 여기서 강조한 것은 새롭고 적절한 지식이 완성된 지식뿐만 아니라 발생상태 그대로의 지식 즉, 과정으로서의 지식도 포함하고 있음을 제안하였다. 세 번째, 수학자가 수학을 탐구하는 과정을 창의성 연구자들이 보듯이 인지과정으로 보는 대신에 한 수학적 아이디어를 이로부터 하나의 완성된 수학적 지식을 완성하기까지의 수학적 사고과정으로 보는 것이 수학교육적 의미에서 교수${\cdot}$ 학습에 의미가 있음을 살펴보았다.

This paper addresses mathematics content knowledge required for teaching in secondary school. Three components of mathematical knowledge are needed for teaching: (i) knowing school mathematics, (ii) knowing process of school mathematics, (iii) making connections between school mathematics and advanced mathematics. We investigated mathematics content knowledge of secondary teachers. We found that secondary mathematics teachers have a lack of understanding in solving realistic problem, reasoning and proof, and making connections between school mathematics and advanced mathematics.

수학 교사의 지식은 교과내용 지식, 일반 교육학 지식, 교육학 내용 지식, 교육과정 지식, 학습자에 대한 지식, 교육적 내용에 관한 지식, 수학 교육 목표, 목적, 가치에 대한 지식으로 분류될 수 있다. 지금까지 이러한 수학 교사에 대한 지식 종류에 대한 학문적 연구는 뚜렷하게 체계적으로 연구되어지지 못하고 주로 저학년 학생 및 학습자 위주로 산발적인 연구가 진행되어 왔다. 수학교사가 지녀야할 지식은 수학 학습자인 학생들을 어떻게 효과적으로 가르치느냐에 가장 직접적인 영향을 미치는 것이므로 이에 따른 구체적인 조사 연구가 필요할 뿐만 아니라 교사교육 프로그램에 반영되어 효과적으로 능력있는 교사를 양성할 수 있도록 하여야겠다.

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.

수학 영재교육이 일반 학교수학교육과 차별화 되어야 한다는 점은 수학적 지식의 습득이 아니라 수학적 지식의 창출에 있다. 수학적 지식의 창출에 적절한 교육프로그램은 산출물을 중시하는 연구과정인데 본 연구는 이것을 성공적으로 수행할 수 있는 프로그램을 소개하며 그 기반으로서 창의적 문제해결과정을 제안한다.

Mathematics students must appropriate their mathematical knowledge which has the definition and theorem of mathematics, algorithm, reasonable thought, heuristic, and mathematics language, and so on. That is, students should construct, use, and apply their own knowledge during learning. Appropriation of mathematical knowledge is practicable when mathematics language is in charge of many functions that Vygotsky cited. To reach the potential development level with mathematics language, students need the zones that they interact themselves and peers, as well as teacher. On that ground, this study presented the interactional zones of IZPD, ZPP, and ZAD, and modeled mathematics learning. By the case of 2 students, we found that ZPP and ZAD were necessary and important.

Research in teachers' knowledge for teaching mathematics (KTM) has been gradually growing for the past several years. With various conceptualizations about what teachers need to teach mathematics, there have been studies to find out the relationship between teachers' KTM and their students' achievement. In this paper, I reviewed various conceptualizations of teacher's mathematical knowledge for teaching, and existing qualitative and quantitative studies about this relationship. Based on the review, I identified the challenges to studying this relationship mainly focusing on the existence of a phase-teaching practice-between teachers' KTM and students' learning. Considering the challenges that have been identified in the literature review, I proposed topics for future studies that would contribute to our understanding how the teachers' KTMare related to their students' achievement, and investigate further about whether and how teacher-student interaction in classroom is related to changes in teachers' KTM.
