In this paper, we compared and analyzed the Korean National Mathematics textbooks of the 2007 amendment curriculum and the Harcourt Math in America focused on fractions and decimals. To summarize the results of the analysis are as follows. First, both textbooks introduce fractions to the meaning of parts-whole concept, but the Harcourt Math is stronger than that of Korean Mathematics textbooks in the concept of unit fractions as a generator of fractions. Second, the fractions can be considered trivial materials - a fraction representing 1 whole, a fraction with it's denominator is 1 - were more clearly represented in our US textbooks than those of our Korean textbooks. Third, in the introduction of the term relating to the fractions, Korea is a strong point of view of the classification of fractions than the point of view of representation in comparison with the case of the United States. Fourth, the equivalent fraction and equivalent decimal concepts were described more detail in the United States of textbooks than those of the case of Korean textbooks. Finally, the approaches of fraction and decimal concepts were introduced more mathematically in the case of the United States than those of the case of Korean textbooks.

In this article, we compared and analyzed the Korean 7th National Mathematics textbooks and Harcourt Math textbooks in America focused on the area of geometry for the elementary school students. We expect that this article would contribute to the elementary school teacher for the reorganization of the elementary school mathematics curriculums.

Under the consideration of Chinese math education tradition and new educational orientation, we compared and analyzed Korea and China's lower-grade elementary school textbooks. The result was that Chinese textbook puts much emphases on practice, skill and repetition, presents condensed contents, provides various learning contents simultaneously, rich humorous expressions, and a lot of implicit representations. From these results, we presented some implications for our mathematics education, future textbook writing, and the follow-up studies.

The addition and subtraction relationship and the multiplication and division relationship are explicitly dealt with in second and third grade mathematics textbooks. However, these relationships are not discussed anymore in the problem situations and activities in the 4th, 5th, and 6th grade mathematics textbooks. In this study, we investigate the calculation principles of subtraction and division in the elementary school mathematics textbooks. Based on our investigation, we justify the addition and subtraction relationship and the multiplication and division relationship at the level of children's understanding so that we discuss some problem situations and activities where the relationships can be applied to subtraction and division. In addition, we suggest educational implications that can be obtained from children's applying the relationships and the properties of equations to subtraction and division.

There are differences in manner to be shown according to a basic point of view about knowledge in division which is traditional algorithm. The 1st and 2nd stage show didactic transpositions less systemic. The 3rd stage, which were influenced by the new math, uses logical mechanism. The 4th stage shows conceptual knowledge of the division independently. The 5th and 6th stage use concrete models which shows a course. The 7th stage constitutes contents systematically and shows many chances which focus on the formation of knowledge. The suggestions derived from such transition should be considered in the practice class and an elementary mathematics textbooks for meaningful learning.

This research was conducted with focus groups interviews targeted at elementary teacher to analyze perceptions on storytelling based mathematics textbooks. As a result, elementary school teacher recognizes the introduction of storytelling as a major change in the revised textbooks. In addition, a change in the appearance of the revised textbook, the role of the Materials package, a change of assessment items, and increased exploration activity and the experience turned out to be having a significant impact on actual classroom as much as the introduction of storytelling.

Euclid's elements have been recognized as a significant textbook in mathematics and mathematics education because of importance of its contents and methodology. This study discussed how the elements is connected with understanding of math textbooks in elementary school, trying to reveal the value for teacher training. First, when details in elementary textbooks were considered in aspect of elements, the importance of elements was illustrated with the purpose of understanding contents of elementary school by examining educational implications. In addition, the study discussed the value of the elements as the place for teachers and would-be teachers to experience math system.

The purpose of this study is to investigate statistical units of elementary school mathematics textbooks upon on the statistical problem solving process to provide useful information for qualitative improvement of developing curriculum and teaching materials. This study analyzed the statistical units from the textbooks of 1st to 6th year along the 2009 revised national curriculum. The analysis frame is based on the 4 phases of the statistical problem solving process: formulate questions, plan and collect data, present and analyze data and interpret data.

The researcher compared the curricula, the textbooks, the methods of didactic transposition, teacher practices of elementary and secondary mathematics education. The study reviewed several mathematics education theories in the aspect of the differences between the two levels. Findings from this study show a little difference between elementary and secondary mathematics education. There are special difficulties in didactic transposition in elementary mathematics education since it is so far from scientific mathematics. From this study we can conclude that further research needs to be done in the area of development of perspectives on elementary mathematics education.

Mathematical symbols concisely represent mathematical contents related to terms by describing their mathematical meanings implicitly. All symbols in elementary school mathematics textbooks are stated as to be read so that elementary school students could understand their mathematical meanings. The same is somewhat true as in middle school mathematics textbooks, however it is often the case that some symbols are difficult to be read and understood because their statements are unclear or different. In this study, we analyze problems and suggest implications on teaching and learning mathematics based on the statements and understanding of reading symbols in middle school mathematics textbooks.
