In this study, we analyzed how the content and achievement criteria of the Geometry domain of Korean elementary school mathematics curriculum have changed. To this end, based on the analysis framework based on the 2015 revised curriculum, the achievement standards for each period were classified into continuous, extinct, and additional types, and their characteristics were examined. In the domain of Geometry, continuous achievement standards accounted for 51% of the total, and there were many achievement standards that remained unchanged in grade and domain. The extinctive achievement standard is 20.4% of the total, and the mathematics contents that were rapidly introduced due to the modernization of mathematics in the 3rd curriculum were eliminated the most from the 4th curriculum, and after the 7th curriculum, With the introduction of staged curriculum and the system of school year group, the contents of learning were either integrated or moved to middle school. The additional achievement standard was 28.6% of the total, and the achievement standard was added the most with the introduction of spatial sensory development in the 7th curriculum. The GAct that the additivel achievement standard is more than the extinction achievement standard in the Geometry domain is the result of the efforts to actively introduce the geometric contents appropriate to the times despite the great flow of curriculum revision of the curriculum reduction. It is hoped that the results of these studies will be used as basic data in the formation of new achievement standards in future curriculum development.

The purpose of this study is to examine the state of problem solving in Korean elementary mathematics. To do this, we considered the meaning of problem and problem solving in mathematics education, and analyzed the mathematics curricula in the longitudinal-latitudinal dimensions respectively. The longitudinal one consists in examining and comparing the all-time Korean elementary mathematics curricula. Meanwhile the latitudinal one consists in examining and comparing the elementary mathematics curricula of Singapore, the United Kingdom, Japan, and France. As a result of analysis, we selected ten sieves for analysing Korean elementary mathematics textbooks according to the 7th mathematics curriculum. By the analysis, we conclude that we teach problem solving quite positively in school mathematics relative to another countries, in particular we have to reconsider some issues including dealing problem solving as a independent content not a process integrated in other contents.

옛날부터 계산을 잘하는 것이 수학적으로 우수하다고 생각해왔으며, 거의 1900년까지도 교육을 받았다는 것은 계산할 수 있다는 것을 의미하였다. 초등학교의 대부분의 시간은 덧셈, 뺄셈, 곱셈, 나눗셈을 배우는 데 투입되었다. 현재에도 초등학교의 교육과정은 기본 교육에 중점을 두어 3R's(reading, writing, arithmetic)을 강조하고 있으며, 많은 교사나 학부모들은 계산능력에 대해 지대한 관심을 가지고 있다. 1970년대의 '새 수학' 운동으로 계산력이 약화되었다는 비난이 쏟아지자 '기본에 충실하자(Back to basic)'는 운동으로 계산이 강화되기도 하였다.(중략)

This paper compared and contrasted the views of effective mathematics instruction by 223 elementary school teachers and 151 middle school mathematics teachers using a questionnaire with 4 main domains (i.e., curriculum and content, teaching and learning, classroom environment and atmosphere, and assessment) and a total of 48 sub-elements. The analysis of results showed that elementary school teachers put their priority on the curriculum and content domain, while middle school counterparts did on the teaching and learning domain. The teachers commonly agreed with instruction which fosters students' self-directed learning ability, reconstructs the curriculum tailored to students' diverse levels, and establishes appropriate interaction between the teacher and students. However, elementary school teachers agreed more than middle school teachers with regard to the 23 elements related to effective mathematics instruction. In contrast, middle school teachers agreed more than their counterparts as for only 2 elements (instruction fostering mathematical representation and instruction eliciting students' learning motivation). This paper includes suggestions and implications related to Korean teachers' perception of effective mathematics instruction.

The purpose of this study is to provide a useful reference for the elementary school mathematics curriculum of Japan. For this research, we compare the new version of the elementary school mathematics curriculum of Japan and Korea. Roughly speaking, Japan emphasized learning through mathematical ability. On the other hand, the case of Korea, a special emphasis was placed on the ability of problem-solving and mathematical communication. These abilities developed on the base of the mathematical knowledge and skill. The ratio of teaching time are high on mathematics, but Japan ensures much more hours than Korea. Finally we will focus on the result for the application process of the primary school mathematics curriculum.

The 2015 national revised curriculum was notified officially the last year. The intent and direction of the revision caused more or less change for mathematical contents to be taught and is expected to cause a considerable change in math class. In the level of elementary school mathematics, it turned that several contents were deleted or moved to the upper grades because the revision focused especially both on reducing students' burden of learning and on fostering the mathematical key competences. This study aims to examine the relevance of the change through investigation of the national curriculums for elementary school mathematics since 1946. The mathematical contents to be analyzed in this study were mixed calculation of natural numbers, mixed calculation of fractions and decimal fractions, position and direction of objects, are/hectare and ton, the range of numbers and estimating, surface and volume of cylinders, pattern and correspondence, and direct/inverse proportionality, which were changed in any aspect relative to 2009 national revised curriculum. Based on the results of these analyses, the discussion will provide some suggestions for setting the direction of elementary mathematics curriculum.

This study starts with the idea that Korean mathematical word 'byon' which means 'side' of polygons or angles is very ambiguous. The purpose of this study is to make the concept and range of 'byon' clear and to suggest the ideas which can help children understand the concept of 'byon'. For this, various dictionary and the past Korean mathematics curriculums are reviewed. As a result, two attributes 'byon' has are identified and some reasons which block children from understanding 'byon' are detected in its introduction method of mathematics text books and inkhorn of the mathematical term. Finally, two different ideas for helping children understand the concept 'byon' are suggested based on the conclusion of this research.
