TPCK is the knowledge of intersection in mathematics, technology, and pedagogy. This study investigated a teacher's change of his TPCK. He participated in the professional development program which was designed to develop mathematics teachers' TPCK. The professional development program was based on using spreadsheets in teaching mathematics. The researcher suggests a consideration for the integration of technology in mathematics education and mathematics teacher education. The program consisted of a four week summer professional development program and three actual mathematics classroom teaching. Ten teachers took part in the program. One teacher who changed his TPCK most was selected to investigate what made it change most. Following teaching practice was the most influential factor in changing his TPCK.

The purpose of this study was to find ways to improve teacher training programs for mathematics teachers' professional development in Korea. To do so, we first investigated current programs for in-service mathematics teachers in Korea. Then five professional development programs for mathematics teachers in foreign countries were searched and described, which have clear concepts of professionalism and distinct strategies in terms of their aims, processes, focal points, financial supports, etc. We then analyzed the advantages and disadvantages and the types of each program. Based on the analyses, we finally discussed what we learned to make mathematics teacher training programs better for their professional development in Korea.

기하는 수학의 기초를 이루는 중요한 영역이다. 그러나 기하교육을 위한 프로그램 설계와 교수전략에 대한 연구가 부족한 실정이다. 그러므로 현장의 수학교사들에 의한 프로그램개발과 동시에 프로그램과 지도방법을 통합하는 수학교사들의 지속적인 연구가 절실히 요구된다. 이에 본 연구는 영재의 특성들을 고려하고 교사 중심의 강의식 수업보다는 토론, 발표, 세미나에 적합한 프로그램을 구안해 보았다. 프로그램 설계의 내용적 면에서는 기하학의 한 방법인 해석기하학과 현재 고등학교에서 다루는 Euclid 초등기하의 한계를 넘어 공선(共線), 공점(共點)의 비계량적 개념의 사영기하학을 도입하였다. 그리고 프로그램을 운영하는 방법적인 면에서는 문제제시단계, 문제해결단계, 수학적 개념추출단계, 수학화 단계, 확장단계의 단계별 절차를 두었다. 이와 같은 수학영재교육 프로그램의 설계 및 교수전략의 목적은 수학영재들을 새로운 문제와 지식을 제안하고 생산하는 수학 창조자를 만들고자 하는데 있다.

As part of developmental research of a student-teaching practicum program, this research analyzed a mathematics preservice teacher's questioning. The practicum program is based on the model of reflective practice in a collaborative inquiry community for learning-to-teach. This paper describes how a preservice teacher's questioning pattern had changed on the program participation and explain how the change in discourse can be considered as an indicator for the pre service teacher's professional development. Suggestions for the future program development are discussed.

본 연구의 목적은 교사들이 갖고 있는 수학 및 수학을 어떻게 가르칠 것인가에 대한 신념과 수업 관행과의 관계를 문헌적 고찰을 통하여 교사 변화를 위한 모델을 제시하는데 있다. 이를 위하여 먼 저 신념에 대한 정의, 신념과 지식의 차이점, 그리고 신념이 교사들의 수업 관행과 어떻게 관련이 있는지를 논의하였다. 신념과 수업 관행과의 상호 관계를 통하여 본 연구에서는 수업 개선 프로그램의 개발을 위한 모델을 개인적 수준, 학급 수준, 및 학교 수준의 세 시각에서 논의하였다. 이들 모델들은 결국 교사의 학습도 학생들의 학습 방법과 유사한 형태를 띄고 있다는 점에서 현재의 주요한 수학 학습 이론들에 근거를 두고 있다. 결국, 교사들의 수업 관행에 큰 영향을 끼치는 것으로 알려진 교사들의 수학적 신념은 위에 논의된 세 요소의 측면에서 수업 개선 프로그램들이 운영될 때 수업 관행과 함께 변화한다는 것을 본 이론 연구에서는 암시해 주고 있다.

In this paper we carried out a survey targeting 185 elementary, middle and high school mathematics teachers to identify their conception, satisfaction, requirements of after-school mathematics education. The survey results show that we need to develop newer programs, reduce teachers' task, build a more effective system for supporting and researching after-school mathematics education, and so on. Using these survey results we understand the facts of existing after-school mathematics education and provide preliminary data for discussing how to invigorate and advance the after-school mathematics education.

The focus of the present study is on examining a research trend of teachers' professional development in mathematics. In do this, this study investigated the meaning and standards of professional development about mathematics, examining the characteristics of successful mathematics education professional programs, and looking for the processes of teachers' professionalization about mathematics. The findings of this study point out as follows: Teachers' professional development about mathematics implies the improvement of the quality of mathematics instruction following improving the quality of mathematics learning through well-structured mathematics teacher education programs. To do this, teachers need to have shared vision about how to teach mathematics, to have profound knowledge related to the mathematics subject, and to actively participate in teachers' professional development programs in mathematics. The results suggest the common characteristics of successful programs of mathematics teachers' professional development. The results of this study suggest that teachers need to have passion and efforts to improve teachers' professionalization about mathematics, and research on teacher professional development should be based on understanding about teachers. Also, more teacher-researchers to connect educational theories with educational practices are recommended, and a model for teachers' professional development program of mathematics appropriate to the context of Korea needs to be developed.

This study investigated the perceptions of beginning teachers about teacher knowledge. Reflections and improvement of their class knowledge have been perceived as the most important factors by beginning teachers. In terms of utilization of actual classes, teacher knowledge, mathematical concepts and correlations such as connection linked to class contents and hierarchy have been used the most. Among the needed teachers knowledge, knowledge of student understanding and mathematics content knowledge was the most essential knowledge that could be mainly formed through classroom experience and teacher training program. On the other hand, knowledge about technology and assessment was not necessary or useful factor for beginning teachers. To facilitate formation of beginning teachers' knowledge, teacher introductory program, mentoring program, interactive relationship with teacher education institutes, curriculum improvement for teacher education institute and the development and dissemination of various teachers training program would be required.

In this study, we carried out mathematics teacher-training course. The topic of this training course is the understanding of content area reading in school mathematics. The teacher-training course is planned to guide mathematics teachers can perform effectively the teaching of content area reading. In particular, we illustrated the pre-service mathematics teacher education practice. Mathematics teachers investigated various teaching strategies that can lead their students read reading materials related to mathematics effectively. In this training courses, teachers reflects on their own experience and they have an opportunity to learn the new strategies that improve their teaching methods. Teacher educator and in-service teachers share and discuss their practices, they have a meaningful learning experiences. In this study, we presented the processes of the teacher-training course and the results of practice. Furthermore, on the basis of the limitations of this study, we suggested recommendations for the future teacher training program.
