This study investigated the understanding of pre-service teachers in relation to the 'fog experiment' in the 5th grade 'Weather and Our Daily Life' unit of the 2009 and 2015 revised elementary school science textbooks. Pre-service teachers who participated in this study were 100 students, who are attending the university of education and taking courses in teaching research. After pre-learning about the 2009 and 2015 revised elementary school science textbooks and guide book, pre-service teachers conducted the experiment in groups. After that, the pre-service teachers individually presented answers to three questions, and the results of analyzing the answers are as follows. First, there were 24 (24%) preservice teachers who explained the difference in fog generation in the 2009 and 2015 revised curriculum with related scientific concepts such as condensation and water vapor, and only 1 (1%) of them explained the difference using the concept of saturation. Second, there were 48 (48%) pre-service teachers who found out the reason for the change in the fog experiment method according to the change in the curriculum. Third, pre-service teachers valued the reproduction and success of experiments rather than the importance of scientific knowledge, and such pre-service teachers suggested the use of alternative experiments or website.

The proliferation of bioinformatics in modern biology marks a modern revolution in science that promises to influence science education at all levels. This study analyzed the contents of standards in the 7th and 2007 and 2009 revised high school biology curricula and compared the contents, amount and the presentation styles of bioinformatics with those of biotechnology in biology textbooks. In result, first of all, there are some vague expressions about biotechnology and bioinformatics in the 7th and 2007 revised curriculum. There is a clear expression about biotechnology in 'life science I' and 'advanced biology' of 2009 revised curriculum. Second, more biotechnology is introduced than bioinformatics in 'science', 'biology I', 'biology II', 'life science I' textbooks. Third, in 'biology for high class' textbook, amount of biotechnology contents in the 2007 revised curriculum didn't increase. An more effort to introduce bioinformatics to science high school student is needed according to revising curricula.

The 2009 revised curriculum emphasizes science writing as a way to foster scientific thinking, creative thinking and communicative abilities. This research attempted to find out the aspects of science writing in science textbooks by analyzing seven versions of the 2009 revised science textbooks. The results of the analysis are as follows. First, it was found that the proportion of science writing pages is small and the amount of science writing differs a lot depending on the kind of textbook. Also, science writing is generally located in the wrap-up part of each unit, and the amount and the number of science writing vary substantially from unit to unit depending on the textbook. Second, it was found that 'scientific knowledge-explanation' statements have the largest proportion and 'STS-assertion' statements have the second largest proportion in terms of topics and styles of science writing in science textbooks. Some 'scientific knowledge-explanation' statements are not appropriate to foster scientific ability because they evaluate reading comprehension of the suggested passage as nonliterary writing, not the writing itself as a method to learn science. Third, it was found that there are many predicates that do not indicate a clear purpose of the science writing contained in science textbooks.

In this study, we analyzed the analogies in the chemistry domain of 27 middle school science textbooks and 8 high school chemistry textbooks developed under the 2009 Revised National Curriculum. A total of 284 analogies (science, 143; chemistry, 141) were identified from the textbooks, which means that 8.11 analogies (science, 5.3; chemistry, 17.6) per textbook and 0.68 analogy (science, 0.66; chemistry, 0.70) per 10 pages were used on average. Compared with previous curricula that the number of analogies gradually increased, the use of analogy was found to be somewhat decreased in the 2009 Revised National Curriculum. The number of analogies found in each textbook considerably varied depending on course, unit, and publishing company. One hundred ninety one different kinds of analogies were used, among which 38(19.9%) were used over twice. Further analyses of the types of analogies indicated that verbal and pictorial analogy, analogy with abstract target and concrete analog, and enriched analogy were frequently used. However, the term 'analogy' and the description about the limitation of the analogy were rarely mentioned. Artificial analogy, teacher-centered analogy, and analogy with low systematicity were also found to be frequently used. Educational implications of these findings are discussed.

This study aims to find out the meaning of characters used in science textbooks by analyzing the roles of the characters on the 2009 revised science textbooks and the extracted sentences and see if there are indications referable to compiling future science textbooks by finding out where the characters are efficiently used and where supplement is needed. Target textbooks among those developed for the 2009 revised elementary school science textbooks are the first and second semester of the 4th-grade. Methods used include analysis on the roles of character-containing questions using character role analysis whose illustration analysis frame is more supplemented/adjusted than those used in the foregoing studies, analysis on character-containing questions using the existing analysis frame, analysis/survey on good cases and cases needing supplement through consultation with a science education expert, two teachers, etc. The result shows that among types of character roles, motivation and material provision are more used than experiment guide, experiment, and observation results. Result of analyzing in-textbook characters by field shows that life sphere is more used than free exploration, energy, material, and earth. Result of analyzing question types shows the order of expanding, anticipatory, transferable and personal questions and there were no reminiscent and evaluative questions. Based on the result of this study, indications on how to use in-science textbook characters more efficiently and developmentally are needed.

It has been suggested that character education, taught only in ethics and social science, should be integrated into other subjects including science education. In terms of inquiry and the nature of science, science education is related to character education, which is emphasized by SSI (Socioscientific Issue) education. Followed by necessity of character education, the Character Education Promotion Act was established in 2015. To investigate what and how character education is conducting in schools, analysis of curriculums and textbooks is needed in terms of elements underlined in the Character Education Promotion Act. For this purpose, this research analyzed general remarks and science sections in the 2009 revised and the 2015 revised curriculums and science textbooks based on the 2009 revised curriculum with regard to essential virtues in the Character Education Promotion Act. Results showed that parts of essential virtues were included in both curriculums, of which elements were inconsistent with those of science textbooks. Curriculums and textbooks reflecting whole elements faithfully need to be developed.

The present study aims to analyze the extent of the use of STS contents in the areas of 'Evolution of Life' and 'Health of Humanity and Scientific Technology' in 'Science' textbooks and to determine whether they meet the goals of the curriculum revised in 2009. The analysis of the 7 types of textbooks according to the STS topics areas indicated big differences between textbooks as little as 16.67% and as much as 58.33%. Also, among the topics associated with STS, 'Space Development and National Defense' and 'Environmental Problems' were not included. In the STS activity areas, the areas of 'Structured Debate,' 'Interpretation of Data,' 'Research and Investigation' showed great frequency. On the other hand, the STS activity areas of 'Field Activities,' 'Problem-solving and Decision-making,' 'Role Playing,' 'Simulation,' 'Case Study,' and 'Research Design' showed small frequency. Analysis of the STS contents for each area indicated 67.57% for the contents relevant to 'the applicability of science' accounting for the largest part whereas 'Understanding of Occupations related to Science' accounted for 1.63%, showing a great difference in their frequency. Seven standards except 'the applicability of science' were included each contents beyond 10% or less than 10% proportion. The STS contents included in the life science area of the 7 types of convergence-style 'Science' textbooks for the high-school accounted for an average of 20.75%, from as little as 12.35% to as much as 26.90%, depending on the publishes.

In this paper, we study inquiry tendency in informatics textbooks for middle school students. These textbooks were written in accordance with 2009 revised national curriculum, and were adopted in schools starting from 2013. Romey analysis was implemented to analyze inquiry tendency in six textbooks using four different criteria-text, data, activity, evaluation. The results showed that some textbooks displayed a low level of inquiry tendency, lacking participation from students and employing an authoritative tone. Among four factors, the 'activity' displayed the highest degree of inquiry tendency while the 'text' retained the lowest level of inquiry tendency. The Romey measures in some sections were zero, thereby indicating room for improvement.

The purpose of this study was to analyze inquiry activities in high school chemistry II textbooks on the revised 2009 curriculum. It also compared them to the textbooks based on the 7th curriculum, which were published by the same companies. The results in this study turned out to be as follows: First, the number of the activities and rate of inquiry activities per total pages were quite different from each publisher, and all of them decreased. Second, there were too many activities for specific inquiry process elements. Third, the types of inquiry activities differ slightly between each publisher. Experimenting and thinking were the most used while practicing was the least. Fourth, in the inquiry context, activities in scientific context were prevalent and activities in usual context were the second most common. Comparing to the text book on the 7th curriculum, the use of technical-social context increased, however, the technical-social context as well as the natural-environmental context were not used enough, as they constitute less than 10% of the activities. From these results, chemistry teachers should introduce a variety inquiry activities in chemistry curriculum for resolving those problems. Also, textbook developer should accommodate the results of research about science textbooks.
