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 vocabularies in elementary mathematics textbooks for grade 1-2 were analyzed according to 9-degree of semantic system. Also, the types of vocabulary were analyzed using general academic words, mathematics specific concept words, and mathematics general concept words. As a result, percentages of 1-degree and 2-degree vocabulary was the most in both grade 1 and 2 mathematics textbooks. It also shows that some of general academic words were 3-degree vocabulary and some of mathematics specific concept words were either unregistered or 1-degree vocabulary. In particular, general academic words, which are 3-degree vocabulary, may be unfamiliar to 1^st and 2^nd grade students. Therefore, students should be given the opportunity to guess and understand the contextual meaning of general academic words from the given contexts in textbooks. The frequency of use of mathematics general concept words in grade 2 textbook increased significantly compared to grade 1 textbook. Since mathematics general concept words are academic and technical vocabulary they should be taught explicitly. Based on the results of this study, implications for vocabulary instruction in mathematics textbooks were discussed.

Although there are various form of statistical graphs in the real world, the statistical graphs in elementary mathematics textbooks are very formalized by the pedagogical constraints. In this study, I examine the frames of statistical graphs and their educational importance, and analyze the frames in Korean, Australian, and MiC textbooks. As a result, the frames of statistical graphs in elementary mathematics textbooks (1) draws students' attention to the components of the graphs, (2) plays a supplementary role in students' drawing graphs by hands, and (3) helps to apply school mathematics to statistical problem solving in real life. The frames of statistical graphs in Korean textbooks is the form of tables focusing on (1) and (2), but these of MiC textbooks has various forms focusing on (3). On the other hand, Austalian textbooks introduced the table-form frames of statistical graphs at the lower graders, but gradually changed to the axis-form frames as the grade level increased. Based on this, a recommendation was drawn on how to deal with the frames of statistical graphs in elementary mathematics textbooks.

Korea and Japan are close countries having a mutual influence on history and have similar cultural and educational circumstances. The purpose of this study was to compare and analyze the textbooks for elementary school mathematics between Korea and Japan. First, it established the theoretical backgrounds through the precedent research comparing the mathematic textbooks between South Korea and North Korea, Korea and India, Yanbian in China, Japan( Fraction part in numeral field. The Plane Figures). Next, it compared and analyzed two countries'(Korea and Japan) textbooks regarding the structural system and concept of units on the basis of the theoretical research. And it included more specific and detail contents in comparison of Korean with Japanese mathematic textbooks focused on the 5, 6th grade.

The purpose of this study is to analyze connection of the field on 'Nutrition and Food' among grades in the Practical Arts and Home Economics. The subject of analysis is 'Practical Arts' textbook in elementary school and 'Home Economics' textbook in middle school and high school. The Practical Arts textbook of 5th, 6th grade and 5 Home Economics textbooks middle school 1st, 3rd and high school. First of all, it is arranged the aim and contents, used analysis connection frame. The following contents are to summarize the result. First, 'Nutrition and Food' unit is presented nutrition, food, meals management in textbook. Second, aim in curriculum is agreed with contents in curriculum, but how to description in textbook is needed agreements. Third, contents in elementary school and secondary school is connection to develope, but contents in middle and high school are repetition. With the results analyzing connection among text contents, it is concluded that contents' connection has more developed and repeated. Specially, contents of Nutrition are mostly developmental contents, contents of Food are that one part is developmental contents and the other part is repeated contents.

If the philosophy of the curriculum is changed when the curriculum is revised, discussion about knowledge viewpoints in the changed philosophy is needed. The purpose of this thesis is to analyze elementary mathematics textbooks(EMT) based on the perspective of constructivism knowledge as basic philosophy of the 7th curriculum and the 2007 revised curriculum and to present aim of textbooks development through the results. According to the results, the number and operation units of 1st and 2nd grades of EMT compiled according to the 7th curriculum and the 2007 revised curriculum didn't reflect the perspective of constructivism knowledge as the philosophy of the curriculum. From the analysis, EMT were not composed so as to agree the perspective of constructivism knowledge that emphasize concepts, conceptua1 principles, variety, integration.

'Sentence posing' is newly given in the third through sixth grade mathematics textbooks of the revised 2007 curriculum to confirm students' understanding on mathematical concepts of definitions. In this paper, we discuss the role of the sentence posing in the third grade mathematics textbooks on the basis of the problems occurred in third graders' sentence posing activities. Overall, it turned out that the role of the sentence posing was somewhat restrictive. Hence the sentence posing needs to be applied to check whether students can properly use the definitions in real life situations. In addition, it is necessary to employ the present role of the sentence posing to confirm students' understanding on mathematical concepts of definitions selectively according to the concepts of definitions.

In this study, we investigated the elements of knowledge and information processing competence of science inquiry activities in grades 3-6 science textbooks. For this purpose, the elements of knowledge and information processing competence were extracted and a framework for analysis was created. Analysis of eight science textbooks for grades 3-6 in elementary school was carried out using the analysis framework. The following results were obtained by the analysis framework: First, we divided the knowledge and information processing competence into five elements: 'collection,' 'analysis,' 'expression,' 'selection,' and 'evaluation.' Second, the elements of knowledge and information processing competence of science inquiry activity of elementary science textbooks were not evenly composed. The science inquiry activities of elementary science textbooks focused on 'collection' and 'analysis' among the five elements of the knowledge and information processing competence, followed by 'expression,' 'selection,' and 'evaluation.' As a result, we found that a science inquiry model or a science instruction model is needed to develop the knowledge and information processing competence in elementary school science curriculum.
