The purpose of this study was to find some suggestions for reorganization of contents about particle concept of matter in Korean science curriculum. For the purpose of this study, authors analyzed features of Korean science curriculum and compared science curricula of Korea, USA, UK, Japan and Finland. From the result of this study, authors find some features and important suggestions about reorganization of contents about particle in science curriculum. First, the sequence of contents about particle concepts in 2009 Revised National Curriculum was similar to that in the 6th National Science Curriculum. And the feature of 2009 Revised National Curriculum showed the articulation of contents about particle concept. If contents about particle concept is increased in elementary science curriculum, the total articulation would be increased. Second, the presenting sequence of atomic structure-first and laws about atom-later should be changed to laws about atomic-first and atomic structure-later. This presenting sequence is grounded by science curricula of other countries, history of science and developmental psychology. And science curriculum of Korea was required specific extended concept statement like science curricula of USA or UK. Also, Korean science curriculum could benchmark Finnish science curriculum if we want to develop some integrated learning activities such as those in STS or STEAM program.

The purpose of this study was to explore middle school students' perceptions about earth systems in order to implement the 2009 revised national science curriculum effectively. A total of 1219 students participated in the survey and asked to determine their basic understandings about earth systems, self-reported knowledge level, and perceived significance level of the 23 earth systems concepts (contents). In relation to students' basic understandings about earth system, approximately 67% students reported that they didn't know about the term of the earth system. Atmosphere and hydrosphere were highly perceived as major component of earth system. However, cryoshere was perceived to be least familiar by the subjects. The findings also showed that students' self-reported knowledge level and significance level about major ESU#4, #5, #6 related concepts (contents) were significantly different by gender. Most of male students were more knowledgeable and perceived more significant than female students. Regarding the difference of the perceived significance level by grade, 10 out of 23 concepts were significantly different. Some implications for implementing the revised curriculum and school fields were discussed.

We analyzed the representations of acid-base models in 4 kinds of Chemistry I and 4 kinds of Chemistry II textbooks of the 2009 revised curriculum, and 9 kinds of Chemistry I textbooks and 6 kinds of chemistry II textbooks of the 2015 revised curriculum in this study. The problems of the textbook were divided into the problems of definitions and the representations of the logical thinking. As a result of the study, the lack of the concept of chemical equilibrium had a problem with the representation of reversible reactions in the definition of the Brønsted-Lowry model in the Chemistry I textbooks of 2009 revised curriculum, it also appeared to persist in Chemistry I textbooks of 2015 revised curriculum which contains the concept of chemical equilibrium. The representations of logical thinking were related to particle kinds of conservation logic, combinational logic, particle number conservation logic, and proportion logic. There were few problems related to representation of logical thinking in Chemistry I textbook in 2009 revision curriculum, but more problems of representations related to logics are presented in Chemistry I textbooks in 2015 revision curriculum. Therefore, as the curriculum is revised, the representations of chemistry textbooks related to acid and base models need to be changed in a way that can help students' understanding.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through survey data and focus group interview on structures of textbooks. First, We collect online survey results which 2333 elementary school teachers participated. Next, We interview focus group(8 teachers) about shapes of textbooks, quantity of learning contents, activities and problems for evaluation in the mathematics lessons. Storytelling is especially issued in the 2009 revised mathematics curriculum. We intensively discuss learning and teaching methods with application of storytelling textbooks; interests of students, role of storytelling textbooks etc. As results of analysis, the positive rate to use the 2009 revised textbooks is relatively high about shapes and activities of textbooks. But there is more considered about storytelling method. Storytelling may be positive on improvement of learning interests and participation of students. In order to develop these advantages, studies in relation of storytelling are more proceeded and teaching materials for teachers are required effectively in order to applicate to the elementary school.

The purpose of this study was to explore the direction of application and quality management plan of science curriculum of elementary and middle school according to the 2009 revised curriculum. In order to do this, nationwide survey was administered. The subject was 126 elementary school teachers and 88 middle school science teachers. It was founded that teachers had negative opinion on the introduction of the grade cluster system. They considered that it was appropriate to link the contents of Science subject with Practical Arts(Technology Home Economics) subject by similar topic. Science classes were implemented without changing the number of class hours in most schools. They recognized the necessity of differentiated instruction in science classes, but they seldom applied the differentiated instruction. And they suggested that the teaching-learning materials, evaluation materials and contents be provided to apply the STEAM. This study designates the following strategic supports for the effective implementation of 2009 revised science curriculum; 1) the science teachers training program to provide useful information for understanding and teaching the 2009 revised science curriculum, 2) the teachers' community in the school, 3) the development and provision of the feasible STEAM plans.

The purpose of this study was to analyze elementary school teachers' implementation for the emphasis on the revision, major contents, teaching and learning method, and evaluation in the 2009 revised national science curriculum. To fulfill the purpose of this study we carried out a survey with 222 elementary school teachers. Main findings of this research were as follows: First, they highly agreed to the increase in class hours and the application of subject classroom, but they had a lower recognition for setting the subject groups. Second, the degree of necessity in discussion and STS was relatively high, but the degree of implementation in science writing, discussion and STEAM was low. Third, in teaching and learning method, they showed a high performance for mutual cooperation, student-led activities and communication, but, a low implementation for open inquiry and instruction considering individual differences. Fourth, in the evaluation of science learning, they showed a high implementation for evaluation based on achievement standards and one based on the understanding and application of basic concepts, but, a low implementation for the development of common evaluation tools. Fifth, it seemed that their recognition for amount, level and interest of science contents and inquiry activities was appropriate and positive.

In this study, the illustrations in the 27 middle school science textbooks developed under the 2009 Revised National Curriculum were analyzed in the aspect of gender-role stereotype, and the results were compared with those of the 2007 Revised National Curriculum. The results of the analyses revealed that male pupils in the illustrations appeared more frequently than female pupils at all grades, and that the gender gap of pupils appeared in the illustrations slightly increased in comparison with those of the precedent curriculum. Similar to those of the precedent curriculum, the gender gap in other activities were particularly large regardless of publishers. In the illustrations of adults, the frequencies of male outnumbered female, and highly gender biased compared with those of pupils to mean that gender bias in the illustrations of adults were not improved at all. While the ratio of female was high in house works, that of male was high in outdoor activities regardless of publishers. The gender gap in outdoor activities increased in comparison with that of the precedent curriculum. Most occupations illustrated were male-dominated, and the majority of scientists were portrayed as male.

The purpose of this study is to figure out the quality of understanding and implementation for teachers implementing the 2009 revised elementary science curriculum achievement standards. To achieve this purpose, in-depth interviews were conducted with 12 participants, and the qualitative contents method was used to analyze interview contents. According to the interview contents, the results of this study can be described as a phenomenon that teachers implementing achievement standards regarded achievement standards as usual, while focusing on evaluation in school. To make clear of this phenomenon, we classified it into two main dimensions. One is the understanding of teachers by implementing the 2009 Revised National Curriculum achievement standards for elementary school science curriculum, the other is its application. Teachers regarded achievement standards as a criterion, but did not have much attention to it during class time. Furthermore, teachers point out the problems caused by lacking available support materials and the material about core achievement standards. When teachers implemented achievement standards, they prefer to give class to students based on textbooks rather than achievement standards, and they usually use it as evaluation criterion. Based on the results of this study, there were three suggestions and they are as follows: First, it is necessary to improve teachers' professionalism on curriculum and it is a must for teachers to have more concerns about achievement standards; Second, to develop accessible support materials for teachers; Third, to improve curriculum implementation systems.

The purpose of this study was to analyze chemistry textbooks and teachers' guidebooks from the perspective of 'Ignorance', one of the important features of model. This is because the emphasis is on developing modeling capabilities for students in the 2015 Revised Curriculum. For this, Arrhenius model and Brønsted-Lowry model were selected as acid and base models in neutralization reaction which are important contents in chemistry curriculum. The analysis criteria of this study were extracted by analyzing previous studies and four general chemistry textbooks dealing with 'Ignorance' related to acid and base neutralization reaction. Based on the analysis criteria, we analyzed nine chemistry I textbooks and teacher's guides and six chemistry II textbooks and teacher's guides of the 2015 revised curriculum. In addition, we analyzed contents of four chemistry I textbooks and teacher's guides and three chemistry II textbooks and teacher's guides in the 2009 revised curriculum for comparison according to revised curriculums. We analyzed the contents related to the concept of 'neutralization reaction', 'neutrality', 'quantitative relation of neutralization reaction', 'degree of ionization', and 'ionization constant'. Based on the results of this study, we proposed a way to present 'Ignorance' of the models in teachers' guidebooks that chemistry teachers can understand 'Ignorance' of model and teach modeling capabilities for students.
