This study examines the differences and similarities of mathematics teachers' subject matter knowledge among England, the Chinese mainland and Hong Kong. Data were collected from a ten-item test in the SKIMA subject matter audit instrument [Rowland, T.; Martyn, S.; Barber, P. & Heal, C. (2000). Primary teacher trainees' mathematics subject knowledge and classroom performance. In: T. Rowland & C. Morgan (eds.), Research in Mathematics Education, Volume 2 (pp.3-18). ME 2000e.03066] from over 500 participants. Results showed that participants from England performed consistently better, with those from Hong Kong being next and then followed by those from the Chinese mainland. The qualitative data revealed that participants from Hong Kong and the Chinese mainland were fluent in applying routines to solve problems, but had some difficulties in offering explanations or justifications.

There is a tradition of advocating the 'two basics' (basic knowledge and basic skills) in Chinese mathematics education. The direct consequence is that Chinese students are able to produce excellent performance in the international mathematics examinations and outstanding results in the international mathematics competitions. In this article, we will present why and how Chinese teachers teach the 'two basics,' and how combine the pupil's creativity with their 'two basics.' Open ended problem solving is a way to meet the goal. The following topics will be concerned: Culture background; the speed of computation; 'make perfect' ; Efficiency in classroom; Balance between 'two basics' and personal development. In Particular, Chinese mathematics educators pay more attentions to the link between open ended problem solving and the 'two basics' principal.

Promoting students' mathematics understanding is an important research theme in mathematics education. According to general theories of learning, mathematics understanding is close to active learning or significant learning. Thus, if a teacher wants to promote his/her students' mathematics understanding, he/she should pay attention to the students so that the students' thinking is in active situation. In the first part of this paper, some mathematics teachers' ideas about paying attention to their students in Chinese high school are given by questionnaire and interview. In the second part of this paper, we give some teaching episodes about how experienced mathematics teachers promote their students' mathematics understanding based on paying attention on them.

Mathematically deductive reasoning skill is one of the major learning objectives stated in senior secondary curriculum (CDC & HKEAA, 2007, page 15). Ironically, student performance during routine assessments on geometric reasoning, such as proving geometric propositions and justifying geometric properties, is far below teacher expectations. One might argue that this is caused by teachers' lack of relevant subject content knowledge. However, recent research findings have revealed that teachers' knowledge of teaching (e.g., Ball et al., 2009) and their deductive reasoning skills also play a crucial role in student learning. Prior to a comprehensive investigation on teacher competency, we use a case study to investigate teachers' knowledge competency on how to teach their students to mathematically argue that, for example, two triangles are congruent. Deductive reasoning skill is essential to geometry. The initial findings indicate that both subject and pedagogical content knowledge are essential for effectively teaching this challenging topic. We conclude our study by suggesting a method that teachers can use to further improve their teaching effectiveness.

Some 400 Secondary One (i.e. seventh-grade) students from 10 schools were provided with non-routine mathematical problems in their normal mathematics classes as exercises for one academic year. Their attitudes toward mathematics, their conceptions of mathematics and their problem-solving performance were measured both in the beginning and at the end of the year. Hierarchical regression analyses revealed that the introduction of an appropriate dose of non-routine problems would generate some effects on the students' conceptions of mathematics. A medium dose of non-routine problems (as reported by the teachers) would result in a change of the students' conception of mathematics to perceiving mathematics as less of "a subject of calculables." On the other hand, a high dose would lead students to perceive mathematics as more useful and more as a discipline involving thinking. However, with a low dose of non-routine problems, students found mathematics more "friendly" (free from fear). It is therefore proposed that the use of non-routine mathematical problems to an appropriate extent can induce changes in students' "lived space" of mathematics learning and broaden their conceptions of mathematics and mathematics learning.

The Hong Kong mathematics curriculum has launched its reform in recent years. It was the first time that a holistic review of syllabi from Primary 1 through Secondary 7 was made. The curriculum development agency also decided to base the reform on sound pedagogical foundations. That was assisted with academic research where the views of various stakeholders were investigated in detail. Surveys were conducted with students, parents, teachers, employers, university professors, and curriculum designers and they give a full picture of mathematics teaching and learning in Hong Kong. The rich data collected should shed light on the development of mathematics curriculum in other regions with similar socio-cultural and educational settings.

본 연구는 고등학교 진학을 위한 입시라는 독특한 수학 교실 배경이 있는 중국 중학교 수학 교실에서 일어나는 교실 담화를 분석하는데 목적이 있다. 이를 위하여 본 연구에서는 수학 교실 담화를 시작 발화로서 교사 발문 통계와 교사 발문 유형별 에피소드를 분석하였고, 교실 담화 구조 분석으로는 특히 다섯 가지 IRF 하위 유형을 밝혀낼 수 있었다. 중국 귀주성 귀양시에 위치한 H학교에 재직 중인 세 명의 수학 교사가 녹화했던 수학 수업 총 15개의 녹취록과 교사 서면 인터뷰 내용을 중심으로 자료를 분석하였다. 본 연구 결과를 보면, 차시별로 평균 20개 교사 발문이 관찰되었고 교사 발문의 사회적 스케폴딩 역할이 있었으며, 교사 발문 유형은 확인형 발문(이해확인 발문, 설명요구 발문, 상세요구 발문, 재확인 발문)과 정보형 발문(정보제시 발문)으로 분류되었다. 그리고 교실 담화 분석에 따르면 IR형 담화 구조는 거의 관찰되지 않았으며, IRF형 담화 구조의 경우는 단편적인 평가, 평가 및 이유, 근거 설명, 평가 및 학생 반응 재진술, 다른 사고나 해법 안내, 그리고 학생 답 수정이나 교사 의견 제시로 구분되었다.

In the present study, the changes of mathematics teachers' verbal feedback between ten years ago and later were examined using a coding scheme on the types of teacher verbal feedback. Based on the analysis, it is found that teachers intend to use encouraging strategies to make responses to students ten years later. In addition, the duration used in communication between the teacher and individual student is being longer while the frequency of communication becomes less compared ten years ago. Meanwhile, the difference between good lesson ten years ago and common lesson ten years later is not so apparent. It can be inferred that the quality of teaching has being developed.

This study introduced a coding method for mathematical problems in the TIMSS 1999 Video Study, which used sixteen indicators to analyze mathematical problems in a lesson. Based on this framework for coding, the researcher analyzed three lesson videos on Binomial Theorem taught respectively by three Chinese teachers, and got some features of mathematical problems in these three lessons.

본 논문은 교수를 위한 중학교 수학교사들의 수학적 지식을 조사한 저자의 학위논문의 일부분으로써, 19명의 한국 및 중국 중학교 수학교사들의 분수 나눗셈(division by fractions)에 대한 개념적 실생활 모델을 조사, 분석하였다. 분수 나눗셈에 대한 이론적 배경을 제공함과 동시에, 실제 현장 교사들이 가지고 있는 분수 나눗셈에 대한 개념적 이해를 조사, 분석함으로써 분수 나눗셈을 효과적으로 가르치기 위한 교사 지식의 구체적 예들을 제공하고 있다. 본 연구에서는, 연구에 참가한 교사들 대부분이 분수 나눗셈을 "역수 곱하기(invert and multiply)"와 같은 전통적 알고리즘에 기초하여 이해하고 있었으며, 분수 나눗셈의 의미를 실생활 모델로 나타내는 교수과제를 성공적으로 수행한 교사는 단 두 명에 뿐이었다. 이러한 현상은 그 교사들 대부분이 가지고 있는 범자연수 나눗셈 모델이 분할 모델 (partitive model)로 제한되어 있기 때문이었다. 하지만, 또 다른 흥미로운 연구 결과는, 교사가 분할모델 만을 가지고 있더라도, 그 모델의 개념적 구조(conceptual structure)를 깊이 이해하고 있을 때는, 그 기본적 개념 구조를 변형하여 분수 나눗셈의 실생활 모델을 응용해 내는 사고의 융통성을 보였다. 본 논문에서는 이러한 교사들의 성공적 사례뿐만 아니라, 주어진 교수 과제를 수행하는데 실패한 교사들의 인터뷰결과들도 분석, 해석하여 제공하였다.
