This study aims to present implications for the appropriate establishment and development of a science-authorized textbook system through an understanding of the process of selecting science-authorized textbooks and analyzing the perception of teachers. Toward this end, this study conducted interviews with five elementary school teachers who participated in the science textbook selection process, surveys on 32 teachers, and analysis on the authors of the textbooks. The result demonstrated, first, that the "opinion gathering" stage was the most important one, and a council was formed in consideration of career and major. Moreover, the evaluation standard was reorganized and used according to the situation of the school. Second, in the process of opinion gathering, the teachers used a method for reviewing the entire textbook for each teacher. Inquiry activities and textbook composition (readability) were crucially considered as internal factors, and teaching and learning materials, such as videos, were deemed extremely important as external factors. The variable of the author, which is an indicator of the reliability and expertise of textbooks, was also recognized as vital. Third, the deliberation by the School Committee and the report by the principal were recognized as the administrative final step after selection. Finally, selecting the most suitable textbooks for each grade group was recognized as more important than arbitrarily unifying textbooks for the third and fourth grades and for the fifth and sixth grades.

The purpose of this study was to analysis total number of 123 SSI programs by SSI criteria. The criteria was consisted of subject, school level, starting point, scientific evidence, social content, use of scientific knowledge, level of conflict of interest, and evaluation and reflection. The results of the analysis are as follows. First, elementary school programs were the most and middle school programs were relatively few. Second, starting point was mainly in the actual situation, the fiction and nonfiction situation, and the situation including the controversy and conflict was less than 10%. Third, it was based on scientific evidence but mainly influenced by individual values and perceptions. Fourth, social contents were developed mainly in ethics/morality/value, political/social life/economy, environment contents. Fifth, the use of scientific knowledge mainly consisted of scientific decision making, scientific critical thinking, and information search. However, science inquiry, risk assessment, and cost effectiveness were less than 10%. Scientific inquiry is the essential factor of science education, and one of core competencies of national science curriculum. SSI program should be able to experience various kinds of conflicts, and to evaluate and reflect through reflection.

This study aims to analyze the types and roles of visualization materials presented in the third- and fourth-grade national and authorized science textbooks based on the 2015 revised curriculum. Using the type and role framework, 17 chapters were analyzed. The analysis revealed, first, that the national and authorized textbooks had different total amounts of visualization data and total amounts of simple illustrations. However, no difference in the amounts of simple illustrations and infographics used in the units was evident. The units that used the most infographics were Life, Earth and Universe, in that order, in both the national and the authorized textbooks. Second, simple illustrations were observed to have role differences according to the type of visualization data, but infographics had no such differences. Specifically, the motivational role in a simple illustration increased in all the authorized textbooks. Third, looking at the frequencies of the infographic subtypes, the Process, Structure, Comparative Analysis, and Timeline types accounted for 86% of the total, but the proportions of those subtypes varied in the national and authorized textbooks. Based on the results of this study, I suggest that to achieve differentiation in the types or roles of visualization materials, changes in the types, processes, and skills of inquiry must first occur, as must changes in the structure of chapters or lessons. Continuous research and discussion on the standards and methods for authorized textbooks are also needed.

The purpose of the study was to assess science achievement of 11th grade students. Science achievement was assessed in knowledge and inquiry domains. The knowledge domain included three sub-areas including memory, understanding and application. The inquiry domain was divided into four sub-areas involving identifying problems, designing inquiry, data analysis and drawing conclusions. The results indicated that overall science achievement of the 11th grade students who participated in the study was at the proficient level. Regarding the knowledge domain, the achievement in the understanding and application areas was at the proficient level, and the achievement in the memory area was at the basic level. In the inquiry domain, the achievement in all the sub-areas except the identifying problems area which was at the basic level was at the proficient level. There were no gender differences in overall science achievement. However, gender differences were found in all the sub-areas except the application area and varied across the sub-areas. Also, there were significant differences in science achievement among regions.

The purpose of this study was to develop performance assessment materials of scientific inquiry skills on 62 scientific activities in elementary science textbook for third and fourth grades. For this study, a total of 318 elementary teachers were sampled and surveys were carried out to examine the status of performance assessment of scientific inquiry skills in school. The classification system of assessment methods by Hart(1994) was also analyzed to create assessment strategy of scientific inquiry skills for elementary school students. Based on the quantitative data analysis, literature study and existing performance assessment materials analysis, performance assessment materials were developed and applied to science classes for third and fourth grades. Teachers and students were interviewed after the classes for asking about merits and improvements and the performance assessment materials were revised.

The students can search and solve the problems for themselves, improve the scientific inquiry skill through the distance learning in the WWW. It also enable them to construct the wide recognition of the STS which is emphasized in the 7th national curriculum. In addition, due to the one-to-one contact in the distance learning the diverse differentiated education can be run. In this paper, we develop the web-based distant learning model which is suitable in the elementary science and emboss those merits of the distance learning.

In this study, the history of science (HOS) presented at the chapter of "Inquiry of science" in high school science textbooks developed under the 6th and 7th national curriculam was analyzed and compared. A total of 57 sections from 19 textbooks (6th: 12 textbooks, 7th: 7 textbooks) were analyzed in terms of the domain and the presentation level of the HOS described. The results revealed that the frequencies of HOS per page of the textbooks under the 7th curriculum tended to be higher than those under the 6th one in all the domains (conceptual, procedural, and contextual), of which the difference in conceptual domain was statistically different. Regarding the describing level (limited and extensive) at the presentation of the HOS, the frequencies of extensive descriptions per page for the textbooks under the 7th curriculum were also significantly higher than those under the 6th one. The improvement of frequencies and presentation level of HOS in 7th national curriculum could help students to understand scientific concept and nature of science and to have an interest about science.

The effective teaching of Earth Science in the classroom should be augmented by field studies of rocks and minerals in a competently designed school rock garden(SRG). The displayed specimens must be correctly identified, labeled and esthetically evaluated. SRG is more than a general garden with just landscaping and it should provide students with freedom of conducting independent inquiries. The composition of the selected specimens should be representative of the bedrocks of region as well as of Korea in general. There are 130 schools in Jeonju-city and 35 (26.9%) have established rock gardens. There is a pressing demand for more gardens and number of display samples in school. The existing displays need improvement because some samples are not correctly identified and labeled. In addition, there is a duplication of rock types as well as lack of important rock types. The number and composition of the displayed rocks and minerals should be related to the school curriculum and reflect representative bedrocks of Jeonju-city and region.

This study intends to explore the content and organization characteristics of elementary school science textbooks in the astronomical domain from the perspective of understanding the astronomical spatial concept. This study analyzed the relevant unit of the achievement criteria in the 2015 revised science curriculum for the 'space' domain in elementary school science textbooks in comparison with that in secondary school textbooks according to the spatial concept analysis criteria by texts, illustrations, and inquiry activities. As a result, elementary school science textbooks were found to be organized around phenomena rather than concepts, targeting observable celestial bodies linked to real life in order to optimize the amount of learning content. However, the learning contents of astronomical observation related to observation and phenomena-centered real life should stimulate the curiosity and imagination of elementary school students and encourage their intellectual participation. Students need to be supported for understanding of the spatial concept to find an answer to the question of 'why'. The content organization for core concepts should be organized around the transferable spatial concept rather than simply focusing on presenting results by accurately describing the phenomena observed by students through scientific practice in order for students to answer various questions that arise in the course of scientific practice.
