본 연구는 고등학교 수학 교과의 6차시 분의 교실 수업을 비디오로 녹화하여 TIMSS 비디오 연구에서 사용한 코드와 현재 고등학교에서 수업 장학을 위하여 가장 많이 사용하는 점수형 수업참관록으로 분석하였다. TIMSS 비디오 연구의 코드를 활용하여 분석한 결과 교실 수업의 다양한 상황과 수업 내용을 자세하고 객관적인 결과를 얻을 수 있으나 1/3정도의 코드는 거의 사용되지 않는 문제점을 보여주어서 우리 나라 고등학교 수학 수업 분석을 위해서는 TIMSS 연구에서 사용한 코드의 수를 줄여서 고등학교 수학 교실 분석에 사용하는 것이 유용할 것 같다. 수업참관록의 요소를 사용한 분석 결과는 단순하고 개괄적이어서 수업 내용을 정확하게 분석하기는 어렵고 단지 수업 평가 정도의 의미를 지닌다. 따라서 수업참관록에 분석 요소를 추가시킴으로서 보다 의미있고 객관적인 수업 장학을 할 수 있을 것으로 사료된다.

수학적 의사소통이 학습과정에서 뿐만 아니라 수학교육의 목표로 강조되고 있으나 실질적으로 초등학교에서 수학적 의사소통 수업에 대한 구체적인 지도방법이나 수업 사례 분석 등의 연구가 미흡한 실정이다. 이에 본 논문에서는 수학적 의사소통 중에서 담화 중심형 의사소통 수업의 성취 요소와 목표를 고려하여 2 4 6학년 수학 수업을 실시한 후, 수업에서 나타난 교사와 학생 간의 상호작용을 분석하였다. 담화 중심 수업을 실시한 세 교실에서 나타나는 공통점과 차이점을 분석하여 수학수업에서 담화 중심의 수학수업 구현에 관한 시사점과 논의거리를 제공하고자 한다.

A well-designed mathematics lesson is the foundation for effective mathematics instruction. Given this significance, this paper focused on analyzing what would be important elements for in-service teachers in planning an elementary mathematics lesson. For this purpose, a total of 27 in-service teachers were asked to write down whatever they would consider important in designing a mathematics lesson. A mathematics lesson plan prepared by a pre-service teacher was provided for the in-service teachers. They were then asked to analyze the strengths of the lesson plan and to provide detailed feedback on how to improve it. The results of this study showed that the in-service teachers tended to analyze the given mathematics lesson plan in terms of what they considered important regarding lesson design. Such elements were specified when the in-service teachers described the strengths and feedback for improvement of the lesson plan. In particular, the aspects of instructional strategies and materials were explained in detail. Based on these results, this paper is expected to provoke discussions on lesson design of in-service teachers and subsequent research.

본 연구는 초등학교 수학에 적용 가능한 수학사를 추출하고 이를 효과적으로 활용할 수 있는 수업 모형을 개발하여, 수학사를 활용하는 수업이 학생들의 수학적 의사소통과 수학적 태도에 어떠한 영향을 미치는지 알아보았다. 이를 위해 실험집단에는 수학사를 활용한 수업을, 비교집단에는 교과서를 활용한 강의식 수업을 실시하였으며, 연구 중에 수집된 자료는 양적 분석과 질적 분석 방법을 병행하여 분석하였다. 그 결과 첫째, 수학사를 활용한 수학수업은 학생들의 의사소통 참여도를 향상시키는 데에 도움을 주었으며, 둘째, 학생들이 수학적 논리를 가지고 자신의 의견을 상대방에게 정당화하게 하였다. 또한 셋째, 수학사를 활용한 수학 수업이 학생들의 수학적 태도를 긍정적으로 변화시키는 데에 효과가 있음을 알 수 있었다.

Mathematical communication has been emphasized not only as the process of learning mathematics but also as the objective of mathematics education. However, little studies have been conducted with regard to what to consider and how to implement in the actual classroom for promoting mathematical communication. Given this background, this paper implemented a mathematics instruction in each of 2nd, 4th, and 6th grade classrooms in which specific learning objectives were considered to promote discourse-based mathematical communication. It then analyzed the degree by which such learning objectives were achieved and the linguistic interactions between the teacher and students in each classroom. This paper finally provided issues and suggestions for effective discourse-based instruction in mathematics classroom by analyzing similarities and differences among the three classrooms.

The purpose of this study is to investigate elementary teacher's beliefs and attitudes about mathematics and how those reflect their teaching practices. For this goal : (1) Designing questionnaire to measure elementary teachers' beliefs and attitudes about mathematics (2) Inquiring into character of elementary teacher's beliefs and attitudes about mathematics after analyzing questionnaire (3) Analyzing two teachers' mathematics teaching practices to understand how teacher's beliefs and attitudes affect mathematics teaching practices.

In this article, I reviewed current state of researches about mathematics instruction in Korea and sought ways and methodologies of future research. I analyzed articles which were published after year 2000 and were targeted to mathematical instruction itself. After collecting articles, I classified them according to research subject, method and analysis framework, purpose and focus, research perspective and keyword. Subsequently, I analyzed tendency of each research and theoretical framework of them. Based on upper results, I drew directivity of mathematics instruction research at two aspects. First, I found and suggested elements with which framework of mathematics instruction analysis should equip. Secondly, I explored main tasks of mathematics instruction research.

The purpose of this study is to explore how a mathematics teacher's beliefs about mathematics and teaching and learning and mathematics and how such beliefs are related to her knowledge manifested in her mathematics instruction. The study illustrates images of teaching practice of an American mathematics teacher in middle grades mathematics classrooms. Results suggest that the teacher seems consistent in teaching in terms of her beliefs about mathematics and learning and teaching mathematics in some degrees. In particular, the teacher's beliefs affected the ways in which mathematics teacher organized and structured her lessons.

One of the main purposes in prospective elementary teacher education is to prepare for teaching each subject matter. For this purpose, it is necessary to explore how prospective teachers may analyze elementary mathematics instruction and they perceive their analytic foci. This study probed in what ways prospective teachers analyzed elementary mathematics instruction using two video cases. The results of this study showed that prospective teachers focused mainly on instructional strategies, specifically with regard to whether such strategies would be adequate both for mathematical content to be taught and for students' characteristics. They also focused on the effective use of instructional materials as well as the case teacher's adequate feedback. Prospective teachers claimed to have analytic foci not only on the degree of attainment of instructional purposes but also on students' responses and interest. Given this result, this paper includes several issues related to help prospective teachers prepare for better teaching.

The purpose of this study is to offer the implication for elementary school mathematics teaching by analyzing teachers' reflection on the cognitive demands of mathematical tasks they give in class. During the setup phase and the implementation phase in math class, the researchers analyzed the change of cognitive demands on mathematical tasks and the factors which had influence on such changes. After teachers' reflection on teaching, the researchers analyzed the change of cognitive demands on mathematical tasks and the factors which had influence on such changes in math classes. As a result, before teachers' reflection on the cognitive demands of mathematical tasks, the higher-level demands of mathematical tasks had a tendency to decline. However, after teachers' reflection on the cognitive demands of mathematical tasks, higher-level demands of mathematical tasks were maintained.
