Science textbooks are very important materials in order to know elementary science learning in Japan and Korea. In this research the 5th grade science textbooks in Japan and Korea are analyzed by an analyzing category. The analyzing category is consisted of knowledge and scientific inquiry. Knowledge is divided by fact, concept, and rule. Scientific inquiry is divided by problem cognition, variable control, experiment planning, observing, measuring, categorizing, inferring, data transformation, predicting, correlation, cause and effect, result, communication, which are 13 subcategories. Analyzing methods are counting the frequency of each subcategory and tabulating the data. The results of this study are: 1. The frequency of scientific inquiry appeared in Korean 5th grade science textbooks is three times more than that in Japanese textbooks. 2. In scientific inquiry category, Japanese science textbooks emphasized observing, predicting, measuring and problem cognition; Korean science textbooks emphasized experiment planning, observing and problem cognition. 3. In knowledge category, fact subcategory is mostly emphasized in both countries.

The purpose of this study is to analyze whether the required cognitive levels of the current 6th graders' science textbooks conform to the children's cognitive levels and to examine the students' sensed psychological difficulty of the current science textbooks. The eighty five students (boy: 39, girl: 46) from one elementary school were participated in this study. The results of the study are as follows. First, the 2/3 out of the contents in the six graders' science textbooks require concrete level of operation and the 1/3 out of the contents in the textbooks requires the formal level of operation. So the 70% students at the concrete operational level are likely to undergo difficulties with the 1/3 contents in the textbooks. Second, the students' psychological difficulty on the science textbooks is relatively low (approximately two out of five points) and there is not any special pattern between the cognitive level of the textbooks and the students' psychological difficulty of the textbooks.

This study is to examine whether elementary science textbooks in Korea and Singapore are applicable to flipped learning. By comparative study we sought to identifying appropriate features of science textbooks for learner-centered teaching. We analyzed text pages on the unit of 'Working of electricity' in Korean elementary science textbook for sixth grade and three chapters of 'Electric circuits, Using electricity, Conductors of electricity' in Singaporean elementary textbook, 'Science : My pals are here!'. We designed evaluating frameworks for science textbooks based on the four pillars of flipped learning. and applied it to 10 elementary teachers evaluate two textbooks. They evaluated textbooks with Likert Scale items and wrote detailed statements and exemplars about their choices. We analyzed the teachers' evaluative descriptions inductively and chose commonly mentioned characteristics. Based on the analysis, we got to the conclusion about specific features of two elementary science textbooks in terms of flexible environment, learning culture, intentional contents, and teachers' expertises. Implications for improving science textbooks towards flipped learning and learner-centered teaching through comparative study were discussed.

The main results of this study were as follows :(1) the more objectives for environmental education in science textbooks of Korea were focused on “awareness of the environment”. While the objectives of the Project WILD of Canada were balanced between each objectives. (2) the more environmental skills in science textbooks of Korea were focused on ‘observation’ and ‘description’, while the environmental skills of the Project WILD of Canada for environmental education focused on ‘analysis’ and ‘observation’. The environmental skills for the environmental education in the science textbooks of Korea were concentrated on ‘observation ’ and ‘description’, while the Project WILD of Canada were balanced between each skills for investigating the environment and the environmental problems. (3) the instructional procedures in science textbooks of Korea for the environmental education were very similar between each activities of the science textbooks, while the instructional procedures of the Project WILD of Canada were very different, and these procedures were very useful for educating the environmental behaviors.

The purpose of this study was to compare the illustrations used in elementary science textbooks of Korea and BSCS in USA, and analyze the types, role, and characteristics of the illustrations. For the analysis, we used 8 elementary science textbooks of the 7th curriculum of science education in Korea from 3rd through 6th grade, and 16 volumes (stage 2 to stage 5) used in BSCS in USA. We examined types of illustrations, including photograph, picture, graphic, cartoon, chart, and their 4 roles such as, motivation, introducing the lesson activity, providing the materials, presenting the learning result. The results were as follows: First, Korean textbooks have more "photograph" type of illustration than BSCS. In BSCS textbooks, diverse types of illustrations were used compared to Korean textbooks. Second, large portion of illustrations in Korean textbooks took a role of providing materials. In BSCS textbooks, the roles of illustrations were more diverse. In BSCS, there were many illustrations to describe students working together with the disabled children, and to explicitly encourage cooperative learning. Considering the findings in this study, educational implications were discussed.

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.

This study analyzed the illustrations presented in the elementary science paper textbooks and digital textbooks under the 2015 revised curriculum in terms of gender role stereotypes. The frequency of pupils and adults on illustrations was counted by gender, and the types of activities and behavior of characters were analyzed. For pupils, paper textbooks showed a higher frequency of girls than boys, and digital textbooks showed similar gender rates. In the aspect of the activity, paper textbooks showed similar gender rates in non-learning activities, but more girls in learning activities. In digital textbooks, the learning activity was balanced by gender, but the non-learning activities presented boys more frequently. For both paper and digital textbooks, most pupils were described to be active regardless of gender. For adults, paper textbooks were balanced in the frequency by gender, but digital textbooks had a higher proportion of men. Paper textbooks showed similar gender rates in out-of-home activities, but more men in housework activities. In digital textbooks, housework activities were balanced by gender, but out-of-home activities presented men more frequently. For both paper and digital textbooks, men appeared in a broader range of occupations than women. Female scientists appeared more than male scientists in paper textbooks, and opposite tendency appeared in digital textbooks. As a result of analyzing the characteristics of adults, both paper and digital textbooks showed gender stereotypes in specific behavioral characteristics.

The aims of this study are to analysis about the contents associated with the ocean environment compared 17 special-subject textbooks to 2 common-subject textbooks, and to make some proposals for construction of contents. The results of it are as follows; 1. Only 17 books among 36 textbooks taught by the fisheries and marine high schools are contained to some contents related with ocean environment. The contents associated with the ocean environment take possession of 90%, 62% each of total pages in the textbooks, 'ocean pollution' and 'ocean environment'. 2. Of compulsory texts, namely, 'general fisheries', 'general ocean' and 'information treatment of fisheries-marine', the former 2 books are composed of 4.5%, 36.2% each relating with ocean environment. But the last one is nothing. 3. Therefore, even a little contents of ocean environment and its conservation, it is necessary to add as the reasonable rate to the characteristics of each book in 36 special-subject textbooks. 4. And also it is shown that the common-subject textbooks,'ocean science', ' earth science I' and 'earth science II', are composed of 35.7%, 10%, 16.7% each. So we'd like to recommend that the contents of ocean pollution and environmental conservation have to add more.

The purpose of this study was to investigate how congruently the learning objectives of Earth Science I textbooks match the 2009 revised Earth Science curriculum. For this purpose, we classified the learning objectives of curriculum and textbooks were into three factors including ability, cross-cutting concepts, and behavioral verbs. The text data were analyzed using the semantic network analysis method. The results are as follows. The learning objectives of textbooks with regard to ability factors mainly emphasized the cognitive and affective domain. In addition, the ability of inquiry performance was emphasized in the learning objective of the curriculum. The textbooks used various sub-frame of cross-cutting concepts in comparison with the curriculum. Both textbooks and curriculum used the term 'comprehension' the most as behavioral verbs. However, most behavioral verbs just remained at the level of cognitive system.

In this paper, we examined informatics textbooks for middle school students in accordance with 2009 revised curriculum through conducting both content analysis and surveys. The content analysis was analyzed the composition and contents of textbooks. Survey questionnaires were based on the authorization criteria and selection standards of informatics textbooks. The content analysis demonstrated that there were discrepancies among textbooks in areas such as the total number of pages, related material, the number of core concepts introduced in each chapter, and the application of software. The survey results showed that two sections - 'Expression and Modification' and 'Text' exhibited the most positive results, and the 'Creativity' section the least. Using the findings above, we present alternative ways to improve qualities of these textbooks.
