The study was planned to analyze the figure concepts teachers have according to the years of experiences based on the two aspects, the subject matter knowledge and the pedagogical content knowledge. Further, it aims to have the results utilized in teacher education and training, and ultimately to help elementary school students to establish the accurate figure concepts. We administered the test to the random sample of 77 elementary school teachers of the grade 3 to grade 6, from nine schools of the Daegu, Ulsan and Gyeongsangbuk-do districts, and we analyzed the results. Correlational analysis between the years of experience and the knowledge showed that the content understanding and knowledge decreases as the years of experience increases, while the experiential knowledge related to the understanding of the students and the pedagogical methods increases as the years of experience increases.

The elementary and middle school curriculum in Korea has been modified periodically to reach today's 7th national curriculum. Although the intent of each new curriculum was to improve education, lack of proper preparation for teachers and students has not made the new curriculums as effective as it could be. Goodlad et al.(1979) suggested that curriculum should encompass all practices including not only knowledge but all the elements of the curriculum and experiences of the student and teachers. The purpose of this paper is to investigate the actual practices of the current curriculum with focus on the use of instructional media in mathematics teaching and learning. A nationwide curriculum survey was carried out with the Goodlad's curriculum inquiry model as the framework. The result shows that elementary and secondary mathematics teachers used textbook manual (for teachers) and practice books most frequently for their class preparation. In addition to these, mathematics teachers also used manipulatives, visual aids, computers, internet, and calculators in a decreasing order. In general, many mathematics teachers did not use much instructional media in their classes and said that there are not enough effective instructional media to use. However, the teachers have positive attitude toward the educational media that they have used. In this study, we analyzed the survey data regarding educational tools, their use and effects to support the development of a new curriculum model in mathematics for a knowledge-based society.

The purpose of this paper is to analyze and discuss the viewpoint dealing with the fundamental figures-point, line segment, and angle-of elementary school teachers. In fact, our main subjects in this article are as follows; how do elementary school teachers deal with the fundamental figures?, what is the general notion about the fundamental figures of elementary school teachers? Our such subjects come from the survey results about the 'fundamental figures in J. A. Ko(2009); the elementary school students have a tendency to regard the fundamental figures as not mathematical figures. In this article, we discuss mainly the meta-cognitive shift in the transform of notion, for example, from 'congruent' concept to 'equal' concept, about the fundamental figures.

This paper proposes a modified category framework derived from VAMP and VIMT projects for describing teachers' mathematical and pedagogical values, and examines the dialectical relations between values awareness/willingness and teaching, based on case studies of student teachers of secondary mathematics from a follow-up project of VIMT. The preliminary results show that student teachers would teach certain values depending on the awareness of values priority, willingness to teach, their teaching capabilities and classroom conditions. So, mathematics teacher educators should provide relevant courses to facilitate student teachers to be aware of their implicit values and be willing to enact these values, and to empower student teachers with the knowledge and experiences to teach the values.

이 연구는 교수학습 이론에서 상황이론을 토대로 미국의 수업 전문성 신장 실천 사례를 분석하고 교사의 학습 지원 방향을 탐색한 문헌 연구이다. 연구의 목적은 수학 교사의 수업활동 개선을 위해 교사의 학습 지원에 효과적인 프로그램의 유형을 탐색하는 데 있다. 연구 내용은 교사의 새로운 교수학습 방법 학습에 관한 상황이론의 내용 분석과 미국의 수업 전문성 신장 프로그램 운영 사례 분석으로 설정하였다. 상황이론은 인지활동이 상황적, 사회적, 그리고 분산적으로 일어난다고 설명한다. 나아가 상황이론은 수업활동의 변화를 위한 교사의 새로운 교수 방법에 대한 학습과 그러한 교사 학습을 어떻게 계속적으로 지원해야 하는 가에 대한 틀을 제공한다. 첫째, 수업전문성 신장을 위한 교사 연수 프로그램은 실제 수학적 태스크 활동을 통해 살펴보고 수학 학습자의 수학적 사고과정을 분석하는 기회를 제공해야 한다. 학습자의 수학적 사고과정에 대한 이해는 교사학습에 매우 중요한 실제적인 도구다. 둘째, 수업전문성 신장 을 위한 교사 연수 프로그램은 교사-교사 혹은 교사-연구자의 협력적 활동을 장려하도록 개발하는 것이 중요하다. 협력적 활동은 교사의 지식 증대와 효과 적인 수업활동을 촉진하며, 협력을 통해 교사들은 새로운 교수 방법에 노출될 뿐만 아니라, 보다 혁신적인 수업활동을 개발하고 적용할 수 있게 한다.

This research elaborated five components for pre-service mathematics teacher training: 1) Mathematical content knowledge, 2) Pedagogical content knowledge, 3) Pedagogical reasoning, 4) System of training, and 5) Mathematics teachers' beliefs. For the effect teaching, mathematics teacher program should be reformed. The key to improvement should be concerntrated on developing knowledge about effective teaching and translating it into algorithms those teachses can learn and incorporate in their planning prior to teaching. A theory of instruction should specify the most effective sequences in which to present the materials to be learned.

This report is intended to document beliefs that engineers working as senior high school teachers have in Mexico. Documents come from the analysis of answers provided for two tasks contained in a questionnaire: one of them is marking statements as true or false in relation to the derivative function; the second one is about solving different problems: calculation of derivative of piecewise functions and the calculation of maximum and minimum of a polynomial function. Results show the strengths, quasi-logical relations and grouping which are verified in their system of beliefs and knowledge.

Investigating mathematics teachers in middle schools by questionnaire and interview, we find some problems of internal professional structure of mathematics teachers in middle schools. These are reflected in five aspects: professional theory, professional knowledge, professional ability, professional morality, reflection and innovative consciousness.

As teachers' competency is evaluated based on their teaching performance. pre-service teachers need to have an opportunity to reflect on themselves by systematically analyzing and evaluating their own lesson planning and teaching performance through self-assessment. In this study, we aimed to examine what evaluation criteria for lesson planning and teaching performance pre-service mathematics teachers consider in the process of self-assessment. This study used a mixed-methods research design. To draw the self-evaluation criteria for lesson planning and teaching performance, pre-service self-reported assessments were analyzed using qualitative analyses. In addition, descriptive statistics were used to investigate the pre-service teachers' distribution across the criteria and check the ratio of pre-service mathematics teachers for each element. As a result, it was disclosed that pre-service mathematics teachers considered eight elements in self evaluating their own lesson planning and teaching performance. In addition, we found that pre-service mathematics teachers tended to consider Pedagogical Content Knowledge (PCK) more than Subject-Matter Knowledge (SMK). Moreover, the results of this study provide educational implications for the curriculum in the pre-service teacher's education program.

이 연구에서는 도형 정의의 재발명에 대해 세 교사가 쓴 lesson play를 통하여, 교사들이 가지고 있었던 정의 개념과 연역적 조직화로서의 정의하기를 가르치고자 할 때 봉착했던 교수학적 문제들을 살펴보았다. 교사들은 lesson play에서 도형의 정의를 주입식으로 전달하지 않았으며 여러 다른 정의의 가능성을 제시하였으나, 연역적 조직화로서의 정의하기를 적극적으로 구현할 수는 없었다. 교사들은 정의를 어떤 용어에 대한 언어적 약속으로 생각하여, 정의를 가르치는 데 있어 연역적 조직화와 같은 과정이 왜 필요한 지를 이해하지 못하였다. 또 수학적 정의의 임의성 및 정의와 정리의 지위가 절대적이지 않다는 사실을 수용하는 데에도 어려움을 겪고 있었다. 이와 같은 결과는 교사들이 도형의 수학적 정의를 자신이 배웠던 방식과 다르게 가르치도록 하기 위해서는, 교사교육에서 단순히 Freudenthal의 이론과 같은 이상적인 교수 방향 및 철학을 소개하는 것만으로는 부족하며, 상식적인 정의 개념과 수학적 정의 개념의 차이를 인식하고 반성해보는 것이 필요함을 보여주고 있다.
