21세기 정보화 시대에는 알고 있는 지식의 대부분이 짧은 생성 주기를 가지게 되어, 다양한 변화의 시대가 될 것으로 예상하며 우리는 이것을 체험하고 있다. 열린수업에 대한 연구가 끝나기도 전에 수준별수업, 이번에는 멀티미디어 수업, 올해는 수행평가와 체험수업 등으로 다양한 변화를 권장받고 있다. 그리고 변화는 더욱 가속될 것이며, 또 다른 새로운 이름의 학습모형이 계속해서 나올 것이지만 그래도 일관된 방향성을 찾는다면, 가르친다는 것이 '지식의 전달'에 근거한 권위적인 모델로부터 '배움의 자극'을 제공하는 학생중심의 수업으로, 개별적인 학습활동과 더불어 소집단 공동학습활동을 중시하여, 발표${\cdot}$토의 활동과 관찰, 조사 등의 자기주도적인 학습능력과 협력 학습능력을 배양하는 쪽으로 바뀌어 가는 것이다. 다음의 예는 구서여자중학교 중심 MathPower 교과연구회에서 수행하고 있는 수학적 힘을 기르는 몇 가지 방법으로, 수학적 개념을 가르치는데 가장 적절한 예는 아닐 수도 있지만, ${\cdot}$ 학습수준을 고려한 교양으로서의 수학. ${\cdot}$ 협동적으로 사고하고 문제를 해결하는 의사소통 수단으로서의 수학. ${\cdot}$ 창의성과 인재에 중점을 둔 수학. 교육으로, 다양한 학습자료의 제작 및 활용으로 교실이 다른 사람과 협동적으로 사고하며, 수학적인 아이디어를 나누는 장소가 되어, 가슴이 따뜻하며, 재기발랄한 아이들이 IQ와 EQ, 그리고 창의력을 두루 맛볼 수 있었으면 하는 바램으로 정리한 것입니다.

학생들이 실세계와 수학적 세계사이를 연관시켜 사고하고 해석하는 방법 및 실제 문제를 해결하는 일반적인 전략의 방법론의 하나가 수학적 모델링(Mathematical modelling)이라고 볼 수 있다. 한편, 수학 교수 ${\cdot}$ 학습 과정에서 구체적인 조작 활동을 통하여 학생 스스로가 지식을 ‘구성(construction)’ 할 수 있도록 해 주어야 한다는 구성주의적 사조가 대두되고 있는데, 본 논문에서는 구성주의적 관점에서 수학적 모델링을 통한 수학 교수 ${\cdot}$ 지도를 위한 활용 방안을 한 예시를 통해서 고찰해 보고자 한다.

This study is to search for a program of professional development of mathematics teachers on the viewpoint of content knowledge of mathematics. To do this, we select algebraic subject as content knowledge for solution of polynomials and develop material for group study based on selected subject. We supply the developed material to teachers and discuss the possibility of application and the acceptability of it. For discussion, we collect data through tests and questionnaire. Through analysing the data, we obtain the positive result.

The purpose of this study is to investigate the meaning and roles of rhymes in oriental mathematics. To do this, we consider the rhymes in traditional chinese, korean, indian, arabian mathematical books and the mathematical knowledge which they implicate. And we discuss the reasons for which they were often used and the roles which they played. In addition, we suggest how to use them in teaching mathematics.

This paper aims to identify the area of knowledge required for constructing test items by comparing the consulting contents with the area of MKT(Mathematical Knowledge for Teaching). This paper collects the consulting results by the consulting group of A provincial office of education from 2007 to 2009, and analyzes and categorizes the results. The knowledge for constructing test items are known by the analysis on the consulting contents. Training and consulting for teachers are necessary to enable them to recognize the importance of these categories and improve the quality of test items.

The purpose of this study is to investigate the educational effects of pre-service mathematics teacher's teaching experiment on problem solving process and to give some suggestions in teacher training curriculum. The central theoretical background of this study is Palya's mathematical problem solving theory. In this study, we selected 21 pre-service mathematics teachers as research subject. And we conducted classroom activity that is constructing their problem-solving teaching design. We collected research data as observation materials, documents, video-service records etc. From these research data, we analysed that pre-service mathematics teacher's teaching experiment on problem solving process showed many significant educational effects. Therefore, we proposed that we need to serve many opportunities of teaching experiment on problem solving process to pre-service mathematics teacher in teacher training curriculum.

The purpose of the study was to investigate the mathematical knowledge for teaching (MKT) of pre-service and in-service mathematics teachers on the concept of vector. 80 pre-service and 124 in-service mathematics teachers were asked to perform three questions based on MKT's subdomain. The results show that pre-service teachers have stronger common content knowledge(CCK). On the other hand, in-service teachers have stronger specialized content knowledge(SCK), knowledge of content and teaching(KCT) compared to those of pre-service teachers. The paper proposes CCK, SCK and KCT about the concept of vector and discusses the relationships between subdomains of MKT.

This study aims to analyze the mathematics items of the 2013-2024 elementary school teacher employment tests in order to identify the knowledge and characteristics required to teach mathematics, and discuss the future direction of improvement of the elementary school teacher employment tests. By using the revised analytical framework of TEDS-M, we found that the proportion of MCK and MPCK differed from year to year and MPCK was relatively dominant. We also observed that the items were heavily focused on particular knowledge domains, cognitive processes, and levels within MCK and MPCK, and a shortage of items desigend to asseess knowledge in the field of assessments and the ability to engage in higher-order thinking. The results from this study suggest the future direction of improvement of the elementary school teacher employment test to evaluate teacher knowledge and ability necessary in an increasingly diverse society.

This study explored preservice secondary mathematics teachers' mathematical knowledge for teaching [MKT]. In order to measure preservice teachers' MKT, we developed items according to Ball, Thames & Phelps (2008)'s domains and conducted to 53 preservice teachers. Also, we interviewed 1 preservice teacher with the items and a set of interview questions. The findings from the data analysis suggested as follows: a) overall, the preservice teachers scored average 30.2 out of 100; b) the preservice teachers appeared to be unable to explain students' difficulties in learning a specific mathematical idea and how they would respond to and resolve such difficulties.

The purpose of this study is to apply the principles of CGI(Cognitively Guided Instruction) into mathematics class in Korean elementary schools and to explore which mathematical concepts Korean students have and how they use informal knowledge and procedures to solve problems. In addition, this study tries to analyze difficulties that teachers might face when they are planning mathematics teachings based on CGI. The conclusions of this study are followings: First, the mathematics teaching based on CGI provides opportunity for students to communicate about mathematical knowledge that they know, The students are sure of their thoughts and learn from others by presentation. Second, the mathematics teaching based on CGI make students think mathematically. The students try to understand the meaning of problems and find various ways. Third, teachers should lead appropriate environment for the mathematics teaching based on CGI. They should offer proper problems and encourage their students to ask and answer questions respectively.
