Mathematics textbooks are substitutive showing real characters of didactic transposition in pseudo-contextualization and pseudo-personalization. This study analyzed statistical graphs in elementary school mathematics textbooks according to the first to the 7th curriculum in Korea. It focused on the didactic principles used in those methods through those view of Didactic Transposition Theory. The features of the elementary school mathematics textbooks in Korea are investigated and described ethnomethodologically according to each curriculum periods in dividing bar graph, line graph, pictograph, graph of ratio, histogram. The teaching sequences and methods of the statistical graphs, order and methods of sub-learning activities, teaming data, matter of the learning activity indicator were summarized. Usually, the teaching sequences, excepting the graphs of ratio, statistical graphs are introduced in the second semester of each grade. The graph of ratio is introduced in the first semester of 6th grade. As a result of analysing sub-Loaming activities, using them increased from the first to the 7th curriculum and its form was fixed constructive and stable at the 4th curriculum textbooks. As a result of analysing the teaming data, the data of the social aspects are used more frequently and the data of the individual preferences trended more gradually. As a result of analysing the matter of the teaming activity indicators, concept-explanation question style were used more frequently. Statement-practice style and consideration style trended gradually. Concluding remarks are: First, the didactic transposition of the elementary school mathematics textbooks developed systematically according to the first to the 7th curriculum; Second, mathematics textbooks gradually introduced the positive learning style of activity and the learners' spontaneousness; Third, more concrete practice activities and reflective activities were variously introduced considering the level and interest of each elementary student.

Even though fractions make up one of the most important concepts in the domain of numbers in elementary math, it is difficult to teach or learn them due to their different quantity concepts and notation methods from natural numbers and their various concepts. The didactic transposition of fractions is thus important, and there is a need to examine the didactic concepts of fractions used in the South Korean textbooks for its research. This study compared elementary math textbooks among South Korea, Taiwan, and China and investigated differences in the instructional time and order of fraction concepts in the textbooks according to their didactic concepts and also differences in the instructional methods according to quantitative concepts.

This study is focused to characteristics of earth region vocabularies used in 7th curricula science textbooks for 3rd to 6th grades of elementary school. The numbers of earth region vocabularies are generally increased from the lower to the higher grade textbooks, ‘science’ and ‘experiments and observation’. In ‘science’ textbooks, numbers and use frequencies of earth region vocabularies are predominant in astronomy and atmospheric science vocabularies. Meanwhile, in ‘experiment and observation’, domains related with astronomy have relatively more numbers of the vocabularies but domains related with geology have higher use frequencies of those vocabularies relative to domains related with another areas. ‘Strata’ and ‘fossil’ of geology vocabularies, ‘air temperature’ of atmospheric science vocabularies and ‘sun’ and ‘planet’ of astronomy vocabularies are commonly the highest frequent in the use for science textbooks and experiment and observation. In the both books, earth region vocabularies are derived from 70% to 80% words of Chinese, below 10% of pure Korean, and rest of other languages. Additionally, cases of pure Korean vocabularies unpacked from professional nomenclatures, ones without previous explanations and multiple vocabulary applications to same phenomena are observed in the both books. Synthesizing above results, it is suggested that the reconsideration of domains related with each area of earth science and vocabulary uses assigned to above cases is necessary, in possible.

Science textbook is the most frequently used teaching material in elementary schools of the United States and Korea. Elementary science textbooks of the United States and Korea are analyzed to find out the educational objectives and characteristics of contents shown in textbooks. About 100 pages each in the first grade and fourth grade science textbooks each nations are selected randomly for educational objective analysis. Life science contents of 1st to 6th grade are analyzed from elementary science textbooks of the United States and Korea. The analyzed textbooks in Korea are 'Wise life,' an integrated subject with social studies and science, and 'science.' The analyzed elementary science textbooks of the United States are Harcourt Science, which is one of the frequently used textbooks. The educational objective framework used includes science knowledge, scientific inquiry, scientific attitude, STS, and philosophy and history of science. The results show science textbooks of the United States emphasize scientific knowledge more than scientific inquiry. Korean science textbooks emphasize scientific inquiry more than scientific knowledge. Elementary science textbooks of the United States present some life science topics redundantly and expose more difficult topics than Korean.

In this study, the characteristics of the reading materials in the chemistry domain of elementary school science and middle school science textbooks and chemistry I and II textbooks developed under the 2009 Revised National Science Curriculum were investigated. The criteria for classifying the reading materials were the types of theme, purpose, types of presentation, and students' activity. The inscriptions in the reading materials were also analyzed from the viewpoint of type, role, caption and index, and proximity type. The results indicated that more reading materials were included in the elementary science textbooks compared to middle school science, chemistry I, and/or chemistry II textbooks. The percentage of application in everyday life theme was high in the reading materials of elementary science textbooks, whereas the percentage of scientific knowledge theme was high in those of middle school science, chemistry I, and/or chemistry II textbooks. It was also found that the percentage of expanding concepts purpose was high in the reading materials of elementary science textbooks, whereas the percentage of supplementing concepts purpose was high in those of middle school science, chemistry I, and/or chemistry II textbooks. Several limitations in the use of inscriptions were found to exist; most inscriptions were photograph and/or illustration; most inscriptions were supplementing or elaborating texts; many inscriptions were presented without a caption or an index; there was a problem in the proximity of inscriptions to text.

This study aims to analyze how the history of mathematics is used in Chinese mathematics textbooks. As a framework for analysis, we categorized nine types of using the history of mathematics in textbooks. We analyzed 18 mathematics textbooks for Chinese elementary and middle schools. As a result, we found that various types of using the history of mathematics were adopted in Chinese textbooks except for explorations of mathematical errors in history. We also noticed three characteristics: preference to using for motivation and reading matters in elementary school levels, high frequencies of using problems from traditional mathematical books and origins of mathematical concepts or symbols, and emphasis on ethnic superiority through the Chinese traditional mathematics. Based on the results of analysis, we discussed and induced some implications for using the history in our mathematics textbooks.

Since textbooks for elementary school mathematics in accordance with the seventh curriculum are 'Class I' textbooks, which are used as one and only one textbooks throughout the country, the following aspects have been considered： In the legal aspect, the contents including the curriculum for mathematics asked of the Writing Committee by the Ministry of Education were reflected; in the aspect of theory of mathematics education, the textbooks are written in a way appropriate to theory of mathematics education; and in the aspect of application of reality, the textbooks are written to help improving mathematics education in classrooms. Therefore, the main frame of writing the textbooks is to make students feel proud enough to say "I have done mathematics", through helping students rationally solve problems surrounding them by themselves with their experiences and activities. In the above viewpoint the following sentence is reflected upon: "Hundred explanations are not equal to one manipulation activity."

The purpose of this research is to analyze Korean teacher textbook use and explore the effective use of textbooks. The researcher surveyed teachers to obtain information relative to their dispositions and views of textbook use, and a subset interviewed to obtain additional insight about these views. For the sample, 278 elementary school teachers were surveyed and a group interview was conducted with 6 teachers. The results showed that many teachers teach all the students simply by following the textbook content. These results suggest that for effective us of textbooks, teachers need to understand how to reconstruct the textbook within an understanding of the textbook authors' intension for the textbook content.

To respond to the announcement of the revised version of science curriculum early this year, it has been necessary to develop new science textbooks which can be appropriate and effective to achieve the goals of the revised curriculum. The system of new textbooks needs to embrace the concerns of cognitive development in scientific knowledge, skills, and attitudes as well as social and cultural demands in the rapidly changing society. To develop an innovative framework of science textbooks, we examined previous studies on textbook analysis in Korea and analyzed science textbooks in the United States, Singapore, and Japan. We analyzed various ways of introducing and developing conceptual knowledge, leading scientific inquiry skills and process, enhancing scientific attitudes toward science, technology, society and the environment in those science textbooks. In the process of framing the structures of textbooks, we focused on ways of increasing educational effects of visualized texts, leaners' interest, user-friendly procedure, scientific inquiry, effectiveness of hands-on activities, scientific reading and writing skills, and usage of workbook. Based on those aspects and analyses of textbooks, we attempted to propose a feasible framework of Grade $3{\sim}4$ Science textbook which can effectively respond to the educational changes and demands in the local and global society.

Ratio and rate are key topics in the area of 'Patterns', but there are various perspectives on them. This study compared and analyzed the perspectives of Korean and Singaporean mathematics textbooks on ratio and rate, and explored how teaching and learning methods develop according to each perspective in terms of quantitative reasoning. To this end, we reorganized the analysis criteria based on some studies, and analyzed the textbooks of the two countries in relation to context, relationship, and representation. The results of the study are as follows. Regarding the context, there were differences in the situations, types of units and use of units of the problems presented in textbooks. In terms of relationship, there were differences in the types of two quantities and relationship of quantities. Lastly, there were differences in the representation of ratio and rate. Through these results, we found that elementary mathematics textbooks in Korea and Singapore take different perspectives on ratio and rate. In particular, the perspective taken by Korean textbooks on ratio and rate had unique points different from that of other previous studies. Considering this Korean perspective, we suggested some implications that could help improve textbooks related to ratio and rate and teach them meaningfully.
