This study was to analyze the subject objectives of Middle school 7th grade Science textbooks based on the Korean 7th curriculum by using Klopfer’s taxonomic system and find out how much compatible they were with the requiring objectives of the curriculum. Particularly, this study makes educational objectives for textbooks coherent wit the requiring objectives of the curriculum, through the analysing the problems. The results are follows. The Middle school science educational objective of the 7th curriculum sets up almost of the objectives through all of the domains of the Klopfer’s taxonomy system, except the operational function (Category G.0), and emphasizes on emotionable domain (Category $H.0\~I.0$) more. However, comparing with an encouragement objective rate of NSTA, Middle school Science textbooks based on the 7th curriculum were published putting more importance in a cognitive domain, and the intention objective (Category I.0) was not mentioned.

The purpose of this study is to analyze the seventh curriculum textbooks and teacher's guides of high school science courses in relation to the generation (mechanism) of magma in subduction boundary and find the incorrect descriptions of the texts and the figures (illustrations) and then suggest some improved schemes. According to the result there are many discrepancies in definition of 'magma' among the textbooks and further little scientific explanations about the formation mechanism of magma in most textbooks, and even no descriptions about that. In addition, the figures are inconsistent with the description of the text and also have some incorrect depiction which might contribute to the forming and reinforcing misconceptions about Plate Tectonics as well as a volcanic activity in subduction boundary. On the basis of the previous researches, therefore, some improved schemes (text descriptions and figures) are suggested. The results of this study should be used as a reference for publishing science textbook, developing science curriculum, and teaching effectively in the high school.

The purpose of this study was to analyze and derive pedagogical implications from elementary mathematics textbooks that align with the revised 2015 curriculum. Specifically, the focus was on the chapters related to simplifying fractions, finding a common denominator, and performing addition and subtraction of Fractions with Different Denominators. The analysis revealed that the overall structure of these chapters was similar across the textbooks, but variations existed in terms of the main activities and the textbook organization. Furthermore, different textbooks employed various types and quantities of visual representations. When designing lesson directions and content, it is crucial to consider the strengths and weaknesses of each visual representation.

고등학교 한국지리 8종 교과서에 수록된 동굴명과 학습 컨텐츠 유형별로 동굴의 특성을 요약하면 다음과 같다. 첫째, 8종 교과서에 수록된 자연동굴의 경우 석회동굴에 대한 사례가 많으며 용암동굴과 해식동굴에 대한 소개는 상대적으로 미약하다. 둘째, 동굴에 대한 학습 컨텐츠의 경우 사진자료의 이용빈도가 매우 높은 편이며 그 외 모식도와 지형도를 이용하여 설명하고 있다. 셋째, 교과서 본문에 수록된 동굴명과 학습컨텐츠에 제시된 동굴의 경우 고수동굴에 대한 내용이 매우 높은 편이며 지역적으로도 충북 단양군을 사례로 한 경우가 많다. 특히, 북한에 분포하고 있는 동룡굴에 대한 소개가 특이할 만하다. 향후 천연자원으로서 자연동굴에 대한 주요 관광수요층인 고등학생들의 자연동굴에 대한 올바른 인식과 간접체험을 위한 학습컨텐츠의 개발이 기대된다. 이러한 학습컨텐츠의 개발과 교육현장에서 적용은 학생들로 하여금 지속 가능한 자연동굴의 보존관리와 환경 친화적인 관광개발 및 관광객의 관람태도가 왜 필요한가에 대한 당위성을 충분히 이해시킬 수 있을 것으로 보여진다.

In this study, we analyzed activities in life science chapters of middle school 'science' textbooks for the 2009 revised Korea national curriculum and examined the difference between the analysis based on scientific practices and the analysis based on inquiry skills. As a results, there was a lot of inquiry skills in the order of 'reasoning', 'observing', 'classification' in the all of grade. In scientific practices, 'data analysis and interpretation' and 'constructing explanations and devising problem solving' were biased. This shows that life science inquiry activities in middle school 'science' textbooks are lacking in diversity in scientific practice elements as well as inquiry skills, and that the goals of the activities are limited. In addition, through the interrelationships between scientific inquiry skills and scientific practice elements, we examined contents relevance in the transition from inquiry function center to scientific practice, and compared with the results of inquiry activities in textbook, The results of this study were matched monotonously due to the tendency to basic inquiry-data interpretation / basic inquiry-explanation. This comes from results of the lack of diversity in activities presented in middle school 'science' textbooks. In this study, it is suggested that efforts should be made to include diverse scientific practice elements in the process of realizing 2015 revised Korea national curriculum from the simple and diversity-less inquiry activity through analyzing the textbooks of the 2009 revised Korea national curriculum.

The purpose of this study was to analyze the STS (science-technology-society) contents in chemistry chapters of middle school science textbooks standardized by 7th national curriculum, and to investigate chemistry teachers' perception of STS education. This study was based on 8 essential elements in STS education suggested by Yager and 9 activities in SATIS (science and technology in society). The questionnaire and interview were used to investigate chemistry teachers' perception. As a result of this study, the average value of the STS contents in chemistry chapters of 7 kinds of middle school science textbooks was 22.4%, and the STS contents were preponderated to essential elements of science application and local and community relevance. And STS contents showed that science 2 textbooks were the most of all and in order of science 1 textbooks and science 3 textbooks. As a result of analysis by activities in SATIS, most activities were practice activity, problem-solving and decision making, and structured discussion. Chemistry teachers' perceptions of STS education were following. There were many responses that STS education was necessary for educational efficiency. On the other hand STS education was unnecessary because there were few effective teaching-learning method related with STS education. From these results, middle school science textbooks have to be complemented because 2 essential elements of the STS contents were preponderated in the science textbooks. And the teaching-learning method connected with STS education will have to be developed for the efficiency of STS education.

The purpose of this study is to derive implications for the design of the next curriculum by analyzing the textbooks designed as a new subject in the 2015 revised curriculum. In the mathematics curriculum documents of , 'related learning elements' are presented instead of 'learning elements'. 'Related learning elements' are defined as mathematical concepts or principles that can be used in the context of artificial intelligence, but there are no specific restrictions on the amount and scope of dealing with 'related learning elements'. Accordingly, the aspects of 'related learning elements' reflected in the textbooks were analyzed focusing on the textbook format, the amount and scope of contents, and the ways of using technological tools. There were differences in the format of describing 'related learning elements' in the textbook by textbook and the amount and scope of handling mathematics concepts. Although similar technological tools were dealt with in each textbook so that 'related learning elements' could be used in the context of artificial intelligence, the focus was on computations and interpretation of results. In order to fully reflect the intention of the curriculum in textbooks, a systematic discussion on 'related learning elements' will be necessary. Additionally, in order for students to experience the use of mathematics in artificial intelligence, substantialized activities that can set and solve problems using technological tools should be included in textbooks.

This study looked at the deviation of each textbook, focusing on the detailed learning content related to the quadratic curve properties contained in high school geometry textbooks. Rather than criticizing the diversity of content elements covered in high school geometry textbooks and suggesting alternatives, it focused on analyzing the actual conditions of content element diversity. The curriculum specifies that the practical application of the quadratic curve should be emphasized so that student could recognize the usefulness and value. However, as a result of the analysis, it was confirmed that the purpose of the curriculum and the structure of the textbook did not match somewhat, the deviation of content elements for each textbook was quite large. In terms of acknowledging the diversity of teaching and learning, the diversity of each textbook on the methods of the introduction and the natures related to the quadratic curve can be fully recognized. But in our educational reality, which is aiming for the university entrance examination system through national evaluation such as CSAT, the results are too sensitive in society as a whole, so the diversity of expressions in mathematics textbooks is sometimes interpreted as a disadvantage of evaluation. It is time to reconsider the composition of textbooks that recognizes the diversity of content elements in textbook teaching and learning and at the same time reflects the aspect of equality in evaluation.

The purpose of this paper is to analyze the elementary school mathematics textbooks according to the mathematics curriculum revised in 2007 which put emphasis on mathematics as a communication, and to find out the implication for improving the mathematics textbook of Korea. Mathematics textbooks are analyzed by five analysis criteria, which are suitability of communication activities, suitability of usage of terms and symbols, suitability of literary expressions, suitability of visual expressions and adequateness of mathematics and curriculum. As a result of analysis, it is found out that communication activities were generally reflected the intent of curriculum but there were incomplete terms usage and literary, visual expressions. So communication among authors, between authors and writers, authors and illustrators is necessary for improvement of mathematics textbooks.
