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.

In this study, we analyzed the proportions of STS content, components, topics, and types of the activities of STS content in the elementary science textbooks developed under the 2007 Revised National Curriculum. The analyses of the results revealed that the percentage of STS content included was 15.9% by the number of pages, and 13.5% by the lesson hour. By the components of the STS content, the proportion of 'application of science', 'science-technology and our life' and 'social problems and issues' were large. Most STS topics were related to the 'effects of technological developments' and 'environmental issue', and the topics of 'family and population' and 'human engineering' were few. By the types of the activities, reading was the most, and investigation and writing were also found. Compared with those of the science textbooks developed under the 7th National Curriculum, the variety of components of the STS content increased, but the proportion of STS content and the variety of activities of STS content decreased in the science textbooks developed under the 2007 Revised National Curriculum.

In this study, the characteristics of the reading materials in elementary school science textbooks developed under the 2009 revised National Science Curriculum were investigated. The criteria for classifying the reading materials were the types of topic, purpose, students' activity, and presentation. The visual images in the reading materials were also analyzed from the viewpoint of type, role, caption type, and proximity type. The results indicated that the number of the reading materials in the 2009 revised science textbooks decreased compared to that of the 2007 revised science textbooks. It was also found that the frequencies of the reading materials expanding concepts of the text and/or requiring corresponding students' inquiry increased. More visual images were used in the reading materials of the 2009 revised science textbooks. However, several limitations were still found to exist; most visual images were illustration and/or picture; many visual images were presented without a caption; there was a problem in the proximity of visual image to text.

The focus of this study was on the comparative analysis in the area of illustrations between the primary school from third grade to the sixth grade between Korean and American science textbooks in order to offer some suggestions for consideration of the Korean science textbooks, which will be revised in 2009. The results are as follows: The number of illustrations per page in Korean science textbooks are more than that of American science textbooks. As the type of illustrations, the ratio of photos is the highest and as the role of illustrations, data provision has the highest percentage in both countries. The motivation role in Korean science textbooks seem to be higher than American science textbook, whereas study summary role is more prominent in American textbooks than in Korean textbooks.

In this study, the illustrations in 16 elementary science textbooks developed under the 2007 Revised National Curriculum were analyzed in the aspect of gender-role stereotyping, and the results were compared with those of the 7th National Curriculum. The frequencies of male and female who appeared on textbook illustrations were counted, and the types of activities and the characters of them were analyzed. Most pupils were found to be active, and female pupils appearing in the textbooks were more than male pupils. In all types of activities for pupils, the difference between male and female was decreased compared with that of the 7th National Curriculum. Male and female pupils were illustrated in learning activities with almost equal frequencies, but male pupils were still more frequently represented than female pupils in other activities. Gender difference in adults was increased and the difference was statistically significant. Gender difference in houseworks was not large, but the difference in outdoor activities was statistically significant. Especially, the jobs of adults were illustrated as male-centered, and scientists appearing in the textbook illustrations were also mostly male.
