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.

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.

Students' interest and motivation of a lesson can be deeply influenced by how their teacher starts his or her lesson. So the introduction part of math classes should be very carefully and thoughtfully designed. The goal of this study is to serve the foundation for developing the practical types of introduction part of math classes and to draw the implications for planning and teaching math classes. For these, 19 lesson plans titled by 'volume of cylinders' composed by elementary teachers and 2 lesson videos on the internet are analyzed. Finally, seven types of introduction parts of math class are probed and several implications are suggested.

Current mathematics curriculum of South Korea suggests that students learn mathematics in school with calculators except that the aim of the math lessons is to achieve calculation skills, but we can't be sure that elementary school students use calculators in math lessons of school. Actually we don't have enough data to identify how many elementary school students use calculators in math lessons. The aims of this study are to compare the ratio of elementary school students using calculators in math lessons of school between 20 countries and to analyse the relation between using calculators in math lessons and the achievements of math through $4^{th}$ grade mathematics test of TIMSS 2015. The results of this study are two. One is that generally $4^{th}$ grade students did not use calculators in math lessons. The other result is that generally there is no relation between using calculators in math lessons and the achievements of the math test through $4^{th}$ grade mathematics test of TIMSS 2015. Only in Hong Kong SAR, students without using calculators have higher achievements than students using calculators. In England and USA, students using calculators have higher achievements than students without using calculators. Finally, researcher in this study suggests some implications on using calculator in elementary schools.

본 연구의 목적은 예비 초등교사의 수학 수업에 대한 자기효능감을 조사함으로써 예비 교사를 위한 수학 교육프로그램 개선에 도움이 되고자 하는데 있다. 기존의 문헌 분석에 의하면 수업에 대한 교사들의 자기효능감은 수업 수행 능력과 학생들의 학습에 크게 영향을 미치는 것으로 알려졌다. 뿐만 아니라 최근 우리가 지향하고 있는 교사들에 대한 학습자 중심 수학 수업으로의 개선과 변화된 수업 방식의 지속성에 매우 유효한 요인이 된다. 예비 초등교사들을 대상으로 한 본 연구 결과에 의하면 이들의 수학 수업에 대한 자기효능감은 보통의 수준에 머물러 있으며, 특히 상당수의 예비 교사들은 자신의 수학 수업에 대한 자신감이 매우 부족한 것으로 들어났다. 이러한 결과는 아마도 현재 교육대학교에서 예비 교사들에게 제공하는 수학 교육과 관련된 과목을 수강할 수 있는 기회가 매우 제한적인 데서 그 원인을 찾을 수 있으며, 이는 또한 수학 교육 프로그램의 초점이 예비 교사들의 수학 수업 능력의 측면에 초점이 맞추어져야 한다는 것을 시사한다. 예비 교사들의 수학 수업에 대한 자기 효능감은 그들이 이해하고 있는 수학 교수법적 지식과 매우 관련이 깊은 것으로 나타났다.

This research intends to give a practice of mathematics lesson-critique and some perspectives on a mathematics lesson in the elementary school level. We carried out a mathematics lesson-critique on a lesson chosen as a good lesson by a local educational district in Korea. The main themes of mathematics lesson-critique were the reconstruction of lesson models, the pursuit of relational understanding, the activation of mathematical communication, and the didactical transformation by a in-service teacher. Meanwhile we confirmed that we need to discuss the properness and adequateness of contents about division of natural numbers given in the elementary mathematics textbook and teachers' guide according to the revised 2007 mathematics curriculum.

This study included eleven elementary pre-service teachers who participated in the first and second teaching practices held by J Education College in 2015. After the pre-service teachers were encouraged to self-reflect on their mathematics teaching using a reflective survey sheet of mathematics teaching expertise, their uses of mathematics teaching expertise were analyzed according to the times of their mathematics practice instructions. The results are as follows: First, as the frequency of their mathematics teaching increased, the pre-service teachers' uses of mathematics teaching expertise increased, especially greatly with seven of them. However, the number of subcategories where the teachers' uses of mathematics teaching expertise increased was different from at least two to seven depending on the teachers. Second, the pre-service teachers who performed mathematics teaching practices four times used more of mathematics teaching expertise than those who did two times or three times. Third, some pre-service teachers who taught two or three times never reached 90% of the total score of any subcategory, even in the subcategory where they showed increase in their uses of mathematics teaching expertise. Fourth, the subcategory of 'reflection before class - teaching perspective - understanding of mathematics subject knowledge' was analyzed as the most difficult one for the study participants, and the reason is, they think, that there are not enough materials on the historical back grounds of mathematical concepts.

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.

This research aims to examine the characteristics and main subjects of the mathematics class-criticism by elementary' teachers. In this aim, we analyzed the mathematics class-criticism by the 11 elementary teachers. As the results of this research, the elementary teachers criticized the mathematics class while understanding and describing the class as it is. And mathematics class-criticism by elementary teachers showed contextual and situational characteristics. Furthermore, the main subjects of mathematics class-criticism by elementary teachers were identified as mathematical communication, teacher's question to foster the students' mathematical thinking, appropriateness of task, motivation for students, concrete operational activity, appropriateness on teacher's mathematical behavior and teacher's use of mathematical term, experience of inductive reasoning. While, we identified the significance of mathematics class-criticism for elementary teachers. The elementary teachers pointed out the necessity and importance of the mathematics class-criticism on the mathematics class in usual context.
