This study aims to analyze the science content in secondary school environmental education(EE) textbooks and the environment-related content in secondary school science text- books. Firstly, a total of 73 EE and science textbooks for secondary students were reviewed, which three kinds of textbooks, secondary school EE textbooks and the 10th grade "Science" textbooks, were finally selected for analysis. Three researchers separately analyzed the textbooks using NAAEE framework(1996) for the development of EE materials. In condition that there was a disagreement in their opinion, they had discussed until they came to an agreement. The results showed that secondary school EE textbooks contained more and deeper science concepts than the 10th grade "Science" textbooks, which were evaluated better in all perspectives of the analysis framework. The 10th grade "Science" textbooks had more various teaching and learning activities than EE textbooks. It it expected that the new EE textbook developers should consider the ultimate goal of EE which focused the affective perspectives rather than the cognitive perspectives.

The Purpose of this study was to analyze STS contents in elementary school science textbooks according to 6th, 7th and revision 2007 national curriculum. The contents of STS were analyzed by the STS elements of Yager and the STS topics of Piel's standard. Major findings from the analyses are as follows: (1) The STS contents in the science textbooks of the 6th curriculum took up 13.7% and increased to 18.3% in the 7th and 19.0% in the revision 2007, which showed that the textbooks followed the goal of the national curriculum faithfully. (2) Based on the STS elements by Yager's standard, most of STS content is focused on 'Application of science', 'Social problems and issues' and 'Local and community relevance'. (3) Based on the STS topics by Piel's standard, most of STS contents are focused on 'Effect of technological development' and 'Society of science'. These results indicate that recent STS education trends are reflected on the 6th, 7th and revision 2007 textbooks well. However, it is suggested that some improvement is needed, such as diversification of topic.

In this study, the types of inquiry activities in the $5^{th}$ & $6^{th}$ grade science textbooks according to the 2015 revised science national curriculum were analyzed and compared according to grade level and science area. Science textbooks for elementary school $5^{th}$ & $6^{th}$ graders contain quite diverse types of inquiry activities, which are student-centered inquiry activities. There were comparatively higher proportions of inquiry types such as experiment & observation and simulation, but relatively lower of inquiry types of investigation-discourse & presentation, discussion, expression. Elementary science textbooks are expected to cultivate science key competencies for elementary school students. Considering the science area, the motion & energy, substances, earth & space, and integration areas had the most experiment & observation among activity types, while the life area had the most simulation activities. Even in some area of the 6th grade science textbook, there was little or no data interpretation, discussion, and simulation activities. In order to achieve the goal of elementary science education, science textbooks should be developed considering the revision of future elementary science curriculum.

This study aims to consider interrelations and reasonability to inquiry elements of environment units in 10th Science textbooks of 7th curriculum on the basis of their inquiry contexts, processes and activities. Frequency of inquiry contexts is 59.9% of the highest value in natural environment context but is 4.0% of the lowest one in techno-industrial context. Measurements, inferences, predictions, experiments, data-interpretations, correlations, conclusionreveals in inquiries are in all the textbooks, but observations and classifications, hypothesis generations, controlling variables, experimental designs and generalizations are not in some textbooks. Discussions, experiments, investigations in inquiry activities are included in all the textbooks. However, inspections are not appeared in the all the books. Based on the above results, social and techno-industrial inquiry contexts in the varied scopes are necessary in the environment curricula with a unified direction. Inquiry processes with pro-environmental behaviors as a last goal might be given into the curricula, having tasks that could be understand unified inquiries. In addition, inspections with effectiveness might be thrown into the scene of education.

In this study, the readability of the texts in the third and the sixth grade science textbooks developed under the 2007 revised science curriculum were analyzed in terms of word and sentence units. In the word unit analyses, the levels of the words in the texts were classified into four categories, 1st to 4th levels. In the sentence unit analyses, the sentences in the texts were classified either a simple sentence or compound/complex sentences, and the average length of the sentences was also calculated. The results indicated that more than 90 percents of the words in the 2007 revised science textbooks were classified as the 1st to the 3rd levels. However, both the kinds and the frequencies of the words in the 2007 revised science textbooks were increased in comparison of those in the 7th science textbooks. In particular, it was found that the increasement in the 3rd grade science textbook was noticeable. The ratio of the compound/complex sentences in the 2007 revised science textbooks were increased in comparison of those in the 7th science textbooks. The average length of the sentences in the 2007 revised science textbooks was also increased.

In this study, we investigated the characteristics of the reading materials in the elementary school science textbooks in order to obtain implications for the effective use of them. The reading materials in the elementary school science textbooks developed under the 7th and the 2007 revised National Science Curricula were analyzed. The criteria for classifying the reading materials were the type of theme, purpose, students' activity, the type of presentation, the type of images, the role of images, and readability. The results indicated that the reading materials in the 2007 revised science textbooks are more systematic than those in the 7th science textbooks in terms of their length and their distribution among energy, matter, life, and earth areas. It was also found that various types of reading materials are presented in the 2007 revised science textbooks covering new themes such as frontier science, job opportunity and career, and environment. In addition, the reading materials in the 2007 revised science textbooks introduce more visual images and the readability of them are also better than their counterpart. However, several limitations were still found to exist in the reading materials of the 2007 revised textbooks; most of them are non-inquiry and explanatory; most of the visual images are illustration and/or pictures. Educational implications are discussed.

Photographs and illustrations are integral parts of current science textbooks' inscriptions. This study analysed and compared the function and structure of photographs and illustrations used in high school earth science textbooks of the 6th and 7th national curriculum. The findings of the function analysis showed that 'illustrative' function was far superior to other functions in terms of frequency and ratio. The illustrative function varied more in the 7th curriculum textbooks, especially in earth science I. 'Explanatory' and 'complementary' functions, which were relatively ignored in the 6th curriculum, significantly increased in the 7th curriculum textbooks. 'Decorative' function increased on the whole. The results of the structure analysis revealed that indexical reference remarkably decreased in the 7th curriculum textbooks, which means the retrogression of co-deployment with main text. 'Multiple' organized photographs and illustrations significantly increased in the 7th curriculum textbooks, while 'pair' and 'series' organization did not show an increase at all. It was suggested in this study that 'inquisitive' function and 'complementary' organization should be supplemented in terms of both function and structure. Moreover, the functional and structural aspects of scientific inscriptions including photographs and illustrations should be utilized by the certification criteria of science textbooks.

This study analysed inquiry process and activities of the inquiry area in the chemistry field of middle school science textbooks by the inquiry elements based on the 7th science curriculum. The purpose of this study is to grasp a degree of reflecting the 7th science curriculum in the 9th grade science textbooks, and to find out educational implications for the various inquiry learning. Overall, for the analysis of inquiry elements, basic inquiry elements except classification were well reflected on the middle school science textbooks in 9th grade. However, for the integrated inquiry elements, interpreting data occupies almost half of them. This phenomenon is shown in the analysis of inquiry process and inquiry activities, as well. Especially, project and field trip introduced in the 7th science curriculum are hardly found in the textbooks. 9th grade is classified as an upper grade in the 7th science curriculum in terms of inquiry level. Integrated inquiry elements and inquiry activity types, however, are not thoroughly reflected in the 9th grade science textbooks. It is desirable that a variety of inquiry learning of 9th grade be implemented by reconstructing inquiry area based on the results of this study. Hence the degree and ratio of utilizing the integrated inquiry elements and inquiry activity types to the inquiry area of science textbook in 9th grade should be studied.

The purpose of this study was to select the basic words of physics for science education which were learned through everyday life or school education and be foundation of learning science. For this, we collected all words in the 'Wise Life' textbooks by 7th and 2007 National Curriculum, and extract the science words. As a result, there were 8,970 words in 8 textbooks of 'Wise Life', and about 18% of them, 1,585 words, were science words. There were 266 kinds of science words and most of them were biology words. And the textbooks by 2007 National Curriculum had more science words than by 7th's. Finally we selected 24 basic words of science only in the physics area by comprehensively considering difficulty, need and frequency.

The purposes of this study were to analyze the level of Earth science vocabularies in the 10th grade textbooks with the Science Word Analysis (SWA) program and to investigate the vocabularies selected by the 10th grade students as difficult ones. For this purpose, we extracted the Earth science vocabularies from eleven textbooks, and classified into scientific and non-scientific vocabularies with the SWA program based on the standard Korean language dictionary. In addition, we investigated the difficulty of each vocabulary by surveying five hundred sixty students with a questionnaire. Results showed that the frequency of the scientific vocabularies that were beyond the designated level was the largest among any other levels in all textbooks. Most of the vocabularies selected by students as difficult ones to understand were classified into out of the level. From these results, it were suggested that the students' cognitive level should be considered when developing science textbooks and difficult vocabularies should be replaced with easy ones without a change of meaning.
