Mathematics preservice teachers' Mathematical Content Knowledge ("MCK") includes not only knowledge for mathematics, but also academic knowledge for school mathematics and mathematical process knowledge. We can consider the items in PISA 2012 as suitable tools to assess process knowledge as well as mathematical content knowledge because these items are developed by competent international educational experts. Therefore, the responses to items with the low percentage of correct answers in conjunction with the mathematical contents were analyzed with focus on FMC. The results showed the reasoning competency in responses using the conditions of the problem and of understanding the conditions after reading the complex problems within the context (i.e. the reasoning and argumentation competency, and communication competency) requires improvements. Furthermore the results indicated the errors due to a lack of ability of devising strategies for problem solving. Based on the foregoing results, the implications towards the directions of the education for the preservice mathematics teachers have been derived.

In this paper, we analyze what the components of mathematics teacher` knowledge are, and find that mathematics teacher need knowledge of three areas: subject matter knowledge, pedagogical knowledge, and pedagogical content knowledge. Studies of practicing teachers suggest that When teachers lack understanding in their respective disciplines, it inhibits them from providing students the best learning opportunities, but that a teacher possessing pedagogical content knowledge provides learners with multiple approaches into learning. Some teachers having sound knowledge of mathematics and students were able to respond appropriately to students' questions, design appropriate learning activities involving a variety of mathematical representations, and orchestrate mathematical discourse in the classroom. Thus, it appears that mathematics teachers' knowledge positively affect teaching and student learning..

The purpose of this study is to confirm the MKT(Mathematical Knowledge for Teaching) of the in-service mathematics teachers on the statistics(Representative value, Degree of scattering) through the comparative analysis between the sub-elements of the MKT. In addition, it is to examine the factors that cause the difference of the subjects' MKT. To accomplish this, by the subject of 12 secondary in-service mathematics teachers, in this study the test items of the MKT on the statistics were developed and data were collected and analyzed. As a result of the analysis of the MKT test sheet, the CCK(Common Content Knowledge) and SCK(Specialized Content Knowledge) of the mathematics teacher was confirmed as a high score, whereas the and KCS(Knowledge of Content and Students) and KCT(Knowldge of Curriculum and teaching) were confirmed as low scores. In addition, through these results, it was shown that the difference in MKT's elements the middle school and high school teachers obtain occurred slightly.

This paper aims to explore whether Learning Study improves teachers' subject content knowledge, pedagogical content knowledge, and attitude toward teaching mathematics. A Learning Study was conducted in a Hong Kong primary school for a research lesson on comparing the size of fractions to explore the new teacher roles.

This article is based on an international collaborative study that aimed to investigate mathematical preparation of prospective elementary teachers in several selected education systems in East Asia. This article reports the Korean portion of the study. A survey instrument was developed to explore not only prospective teachers' knowledge of elementary mathematics curriculum and their beliefs in their preparation and mathematics instruction but also their subject matter knowledge and pedagogical content knowledge on the topic of fraction division. A total of 291 seniors in 3 universities participated in the survey. The results reveal these prospective teachers' strengths and weaknesses with regard to their knowledge of fraction division, and suggest that content-specific pedagogical knowledge needs to be emphasized in the teacher preparation program.

본 연구는 정규분포에 관한 예비 수학교사의 수학교수지식(Mathematical Knowledge for Teaching)을 수학교수지식의 하위 요소 간 비교 분석을 통해 확인하고, 예비 수학교사의 수학교수지식의 하위 요소 간 차이가 발생하는 것을 확인해 보고자 한다. 이를 위해 예비 수학교사 24명을 대상으로 정규분포에 관한 MKT 검사지를 제작하여 검사를 실행하여 자료를 수집하였다. MKT 검사지 분석 결과 예비 수학교사의 일반 내용 지식(Common Content Knowledge)은 비교적 높은 점수의 결과로 확인된 것에 비해 특수 내용 지식(Specialized Content Knowledge)과 내용과 학생에 대한 지식(Knowledge of Content and Students)에 관한 결과는 비교적 낮은 점수로 볼 수 있었다. 또한, 이러한 결과를 통하여 예비 수학교사의 MKT의 차이가 발생하는가를 알아보고자 하였다.

This study investigated elementary teachers' subject matter knowledge and pedagogical content knowledge of fractions. The subject for data collection were 12 in-service elementary teachers and data were collected through written test problems. The finding imply that most elementary teachers understand fraction construct as part-whole, show low level of understanding of operator, ratio, and measurement constructions and word problem posing, using models, and developing the algorithms to divide fractions. The research results indicates that experienced teachers possess poor knowledge of fractions against novice teachers.

본 논문은 예비교사들이 함수교육과 관련된 subjective-matter knowledge와 pedagogical content knowledge를 어떻게 효율적으로 의미있게 학습하고 발전시키는 가에 대하여 조사하였다. 함수의 기본개념과 원칙, 그리고 그들이 어떻게 조직되었는지를 이해하는 능력과 의미있는 함수학습이 가능하도록 그들을 표현하고 구성하는 능력을 증진시키기 위하여 본 연구에서는 구성주의와 협동학습에 기반 한 학습방법을 채택하였다. 사전, 사후테스트와 인터뷰를 통하여 평가한 결과 소그룹 구성원들과의 상호작용 결과를 전체 구성원과의 토론을 통하여 학습하는 과정에서 보다 깊이 있고 확장된 subject-matter knowledge와 다양한 pedagogical content knowledge를 획득하게 되는 결과를 얻게 되었다.

이 연구에서는 함수 영역에서 현직 중등 수학 교사들의 교수를 위한 수학적 지식 (Mathematical Knowledge for Teaching, 이하 MKT) 수준을 검증할 수 있는 문항을 영역별로 개발하고, 이를 이용한 검사를 통해 중등 수학교사들의 함수 영역의 MKT 수준이 어떠한지 알아보고자 한다. 이를 위해 먼저 고등학교 1학년 수준에서 함수 영역에 대한 검사 문항을 개발하여 서울 지역의 총 5개의 고등학교 현직 수학 교사 34명을 상대로 검사를 실시하여 자료를 수집하여 분석하였다. 자료 분석 결과 교사들이 얻은 점수를 백점 만점으로 환산 시 검사지 총점의 평균은 67.4점으로 나타났는데, Common Content Knowledge[CCK], Knowledge of Content and Teaching[KCT] 영역의 점수에 비해 Specialized Content Knowledge[SCK] 영역의 점수가 낮게 나타났다. 또한 각 영역별 총점을 상관관계 분석을 통해 살펴본 결과 SCK, KCS 그리고 KCT 영역이 서로 통계적으로 유의미한 상관관계가 있었고 이와 다르게 CCK와 나머지 영역들 간에는 통계적으로 유의미한 상관관계는 나타나지 않았다.

It is the development of a mathematics teachers' teaching knowledge that manifests a mathematics teacher's professional knowledge growth. It is becoming a direct and effective approach of conversion of mathematical knowledge into the knowledge of mathematics teaching. Through the investigation, the study revealed that the knowledge conversion process of mathematics teachers in middle school is restricted by three aspects including eight factors. From this point, the authors have structured the path and model on influencing factors of middle school Mathematics Teaching Knowledge Conversion (MPCK), and discuss the mechanism of the transformation process.
