Researchers at Truman State University in Missouri, located in the heartland of the United States, have been using materials adapted from the English translations of the sixth national primary mathematics curriculum from Korea for professional development and assessment with groups of Missouri teachers for the purpose of enhancing teachers' understanding of the fundamentals of mathematics since 2002 [gecKo Mathematics (2008). Korean Mathematics in American Classrooms. Edited by J. Grow-Maienza. Adapted from Korean Mathematics (2001). Kirksville, MO: Truman State University. http://kmath.truman.edu/]. A professional development initiative for 50 teachers conducted in Missouri this past year is reported here. Significant gains in teacher understanding of fundamental mathematics concepts and pedagogy necessary for student achievement in primary mathematics were found as a result of the initiative.

본 논문에서는 수학 교실 수업 관찰 프레임인 "효과적인 수학 수업의 다섯 가지 필수 측면 프레임"을 한국어로 소개하고, 이 프레임을 이용하여 한국의 고등학교 수업을 분석한 결과를 논의한다. 교사의 교수 행동에 초점을 맞추어 교사를 평가를 하였던 기존의 많은 수업 관찰 프레임에서 보여졌던 것과는 달리, "효과적인 수학 수업의 다섯 가지 필수 측면 프레임"은 교실 수업에서 학생들에게 어떤 질 좋은 배움의 기회를 제공하고 그 기회에 학생들이 참여하게 하는 지에 초점을 맞추고 있는 것이 큰 특징이다. 본 고에서는 단순히 이 프레임을 번역하여 소개하는 것이 아닌, 연구 수업 및 교사 공동체가 학교와 교사의 문화로 자리매김한 한국 상황에 맞게 적용하여 한국 고등학교 수업을 케이스 스터디로 분석한 것으로, 한국의 학교 문화에 적용할 수 있는 시사점을 제시하고 있다. 또한, 본 고의 말미에서는 "효과적인 수학 수업의 다섯 가지 필수 측면 프레임"의 다른 버전인 교사 전문성 신장 가이드를 이용하여 교사들과 교사 연수자들이 수학 교실 수업 개선을 목표로 하는 교사 전문성 신장에 관한 실천적 측면의 함의점을 논한다.

This paper compares and analyzes mathematics teachers' understanding of students' mathematical comprehension after experiences with the Cognitively Guided Instruction (CGI) or the Development of Mathematical Ideas (DMI) teaching strategies. This report sheds light on current issues confronted by the educational system in the context of mathematics teaching and learning. In particular, the declining rate of mathematical literacy among adolescents is discussed. Moreover, examples of CGI and DMI teaching strategies are presented to focus on the impact of these teaching styles on student-centered instruction, teachers' belief, and students' mathematical achievement, conceptual understanding and word problem solving skills. Hence, with a gradual enhancement of reformed ways of teaching mathematics in schools and the reported increase in student achievement as a result of professional development with new teaching strategies, teacher professional development programs that emphasize teachers' understanding of students' mathematical comprehension is needed rather than the currently dominant traditional pedagogy of direct instruction with a focus on teaching problem solving strategies.

Research shows that formative assessment has a more powerful effect on student learning than summative assessment. This case study of an 8th grade algebra classroom focuses on how the implementation of Formative Assessment Lessons (FALs) and the participation in teacher learning communities related to FALs changed in the teacher's instructional practices, over the course of a year, to promote students' mathematical reasoning and justification. Two classroom observations are analyzed to identify how the teacher elicited and built on students' mathematical reasoning, and how the teacher prompted students to respond to and develop one another's mathematical ideas. Findings show that the teacher solicited students' reasoning more often as the academic year progressed, and students also began developing mathematical reasoning in meaningful ways, such as articulating their mathematical thinking, responding to other students' reasoning, and building on those ideas leading by the teacher. However, findings also show that teacher change in teaching practices is complicated and intertwined with various dimensions of teacher development. This study contributes to the understanding of changes in teaching practices, which has significant implications for teacher professional development and frameworks for investigating teacher learning.

본 연구에서는 2013년 중등학교 1급 정교사 자격 연수에 참가한 수학 교사 68명을 대상으로 산파법의 이해와 적용을 위한 교사 전문성 신장 연수 과정을 실행하였다. 총 3차시로 구성된 연수 강의에서 산파법의 개요와 특징, 산파법 수업 실행 사례 분석, 산파법 실행 실습, 산파법 대본 사례 검토, 선행 연구에서 드러난 산파법의 교육적 적용 방안을 다루었다. 연수 실행 전 후로 실시된 설문 조사의 기록 과정을 통해, 교사들이 자신의 지식에 대한 반성적 검토의 기회를 갖고 산파법 구사를 위해 더 공부해야 할 부분이나 극복해야 할 과제에 대해 생각해 볼 수 있도록 안내하였다. 연구 과정에서 수집된 조사기록지의 기록물 자료를 바탕으로 산파법의 교육적 적용과 관련된 현직 교사들의 지식 및 인식의 변화를 분석하고, 분석 결과에서 함의된 교사 교육에의 시사점을 도출하였다.

본 연구의 목적은 커뮤니티 환경 아래에서 수학 교사들을 이해하고 고등학교와 대학 간의 협력을 통한 전문성 발달에 관한 연구에 기여하기 위함이다. 본 연구에서는 학습 커뮤니티를 형성하는 데 있어서 수학 교사들이 어떤 어려움을 가지는 가에 관해 조사하였다. 미국의 남동부 지역의 한 프로젝트의 자료를 이용하였으며, 세 명의 예비 교사와 세 명의 멘토 교사,그리고 한 명의 대학에서 나온 교사가 학습 커뮤니티에 속하여 함께 일하였다. 연구 자료는 관찰노트, 인터뷰, 설문지, 이메일 내용 등이 포함되고, 사례 연구와 내러티브 분석법으로 자료를 분석하였다. 연구 결과, 참가자간의 파워 이슈, 논의할 주제 선택이나 서로에 대해 비판하기, 목표를 공유하거나 시간과 멤버 수 조절하는 것 등의 어려움을 나타내었다.

This study conducted a survey to examine the knowledge formation and utilization of computer among beginning teachers of secondary school mathematics. We found that beginning teachers who had more experiences of taking computer utilization classes at teacher education institutes showed more interest in computer and saw the necessity and effectiveness of computer usage for teaching students. Teachers chose GSP the most among computer utilization knowledge learned in pre-service teachers program, and GSP is used the most in mathematics classes. However, they answered that computer is not so much available in class due to lack of hours and the relevant resources. Lastly, beginning teachers answered that the computer knowledge learned in in-service teacher program was more useful than that in pre-service. Thus, the professional development in utilizing computer should be improved through diversifying teacher training contents for beginning teachers as well as for pre-service teachers in teacher education institutes.

The aim of this study was to explore teachers' values about teaching mathematics in the classrooms which implemented Lesson Study and Open Approach as a teaching approach. The targeted group was 83 school teachers from 4 schools participating in a teacher professional development project. The data was gathered through teacher questionnaires, lesson observations and interviews. Data analysis is based on Bishop's (1988; 2003; 2007) and Komin's (1990) frameworks. The results from the implementation of Lesson Study and Open Approach in Thai classroom found the different of the roles and behaviors of teachers and students in classroom. The results revealed 3 kinds of values about teaching: Mathematical values, General educational values, Mathematics educational values and also found that most of the teachers valued problem solving as an innovative teaching approach as against traditional approaches they were familiar with.

The purpose of this study was to explore how pre-service elementary school teachers participate in a course specifically designed to help them learn how to analyze instruction in terms of the levels of cognitive demand of mathematical tasks. This paper describes what prospective teachers learned while reading the cases of "implementing standards-based mathematics instruction", analyzing all tasks of one unit in one elementary mathematics textbook, observing master teachers' mathematics instruction as well as their colleagues during the practicum period, and developing their own cases on the basis of the design and implementation of instruction focused on mathematical tasks. This paper includes various reflections of the prospective teachers.

This study aimed to explore teachers' perceived beliefs regarding teaching practice in the context of three-year Professional Development Project (ProDev) implementing lesson study incorporating Open Approach. The data were collected through questionnaire distributing to the teachers in three schools. Qualitative data were collected through participatory observation on teaching practice and interviewing members of lesson study team. The findings revealed that teacher's perceived beliefs regarding teaching practice could be categorized into three categories according to 3 phases of lesson study as the followings: 1) Perceived beliefs related to collaboratively designing research lessons 2) Perceived beliefs related to collaboratively observing their friend teaching the research lesson 3) Perceived beliefs related to collaboratively doing post-discussion or reflection on the activities of the two phases.
