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.

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 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.

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.

This article reviews several classroom observational frameworks and introduces one of them, Teaching for Robust Understanding of Mathematics (TRU Math) framework, in more detail. The TRU Math framework has unique features, especially of which it helps researchers and practitioners analyze lessons with a focus on opportunities to learn and on how students access to the learning opportunities in mathematics classrooms rather than focusing on teacher behaviors. In this article, using this TRU Math framework, a Korean high school mathematics lesson was analyzed. The analysis illustrates the aspects of good mathematics teaching according to the five dimensions that we theorized. It provides implications on how to better use the tool for both research and practice in Korean school culture and teacher professional development contexts.

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.

The purpose of this study is to understand the public education system in Korea, that features many pre-taught students, and to figure out how elementary school teachers teach them. To accomplish this study, 204 elementary school teachers in Seoul participated in a survey and the frequency and percentage were made. In addition, to add more depth to this study 5 elementary school teachers had several interviews. We obtained the following results. First, elementary school teachers generally think that the situation with many pre-taught students have had a bad effect on public education and pre-taught students are drilled but cannot understand what they have learnt. They also answered that they have low morale when teaching pre-taught students. Second, a large number of elementary school teachers think the situation with many of the pre-taught students does not help the public math education system, which influences the teachers' teaching style. Teachers who answered negative on pre-taught students are running their math classes focusing on understanding math concepts and activities. On the other hand, few teachers who answered positive on pre-taught students did not care about the situation with many pre-taught students.

This research aims to compare and identify the prospective elementary teachers' perspectives on mathematics class. In this aim, we analyzed the comments on the mathematics class by the prospective elementary teachers (senior students and junior students) who are differ in the time of study in the University of Education. As the results of this research, the senior students commented the mathematics class by applying the theories in mathematics education, but the junior students did not. Furthermore, the senior students had the more rigid perspectives on mathematics class and commented in more depth on mathematics class in comparison with the junior students. While, the senior students showed a weak point that they overextended and over-applied the some mathematics education theories in the comments on mathematics class.

This paper investigated the views of effective mathematics instruction on the part of school administrators, and then compared and contrasted such views with those of elementary school teachers based on the previous study. A total of 32 school administrators participated in this study and responded to three types of the questionnaire. The results of this study showed that school administrators regarded good mathematics teaching as using concrete materials and teaching students to think. School administrators put their first priority on curriculum and content among four main domains of good mathematics teaching, and did on constructing curriculum among seven sub-domains of good mathematics teaching. They agreed that good mathematics teaching includes teaching by reconstructing the curriculum according to students' various levels and teaching to emphasize the connection among mathematical concepts. However, they thought that good mathematics teaching might not include teaching for fluent calculation or teaching in well-equipped learning environment. The results of comparison of perspectives regarding good mathematics teaching between school administrators and teachers showed remarkably similar tendency. However, a noticeable difference was that school administrators agreed more than elementary school teachers with regard to the 20 elements related to effective mathematics instruction. This paper closes with implications based on the similarities and differences regarding effective mathematics instruction perceived by school administrators and teachers.

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.
