Despite the rapidly growing body of research on science teachers' pedagogical content knowledge (PCK), most of the research has mainly focused on the definition of PCK and its components. The main purpose of this research was to explore the operational definition of PCK and to suggest another form by re-conceptualizing PCK, with the newly defined and conceptualized PCK capable of being used as standards and/or criteria in selecting the curricular content of and deciding the subject area of science teacher education. In this research, the science teachers' PCK was defined as the "practical knowledge and skills that are acquired through the curriculum of science education and in the course of teaching experiences, and which are used in their teaching of secondary school science." The science teachers' PCK was further defined as consisting of two integrated and/or combined dimensions: subject matter and pedagogy, each of which comprises several components. In this paper, the PCK is called science education literacy. The paper also presents the ways to apply the operational definition of PCK and re-conceptualized PCK and a few suggestions for the research on science teachers' PCK.

We developed $21^{st}$ century scientific literacy assessment instrument and applied it to explore the contents of seven Korean science textbooks. The $21^{st}$ century scientific literacy assessment instrument involved three dimensions (habits of mind, character and values, science as human endeavor). Each dimension consists of three sub-dimensions. Five science education experts assessed the content of textbook using criteria. We discussed issues in which the examiners responses did not match and reached an agreement on initial disagreement. As a result, we found that most Korean textbook contained contents on habits of mind, especially, communication, collaboration, and information management. We also found that most materials lacked information about character and values and science as human endeavor. Based on the result, we suggest that researchers and science educators need to consider all dimensions of the $21^{st}$ century scientific literacy when they develop curriculum and teaching materials. In addition, the rubric for $21^{st}$ century scientific literacy can be adopted as an assessment tool for examining curriculum, teaching materials.

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.

The secondary science teachers' professional needs and their preference for training method between off-line and on-line education were investigated. A nation-wide survey was administered to 145 science teachers from 106 secondary schools. The respondents showed high demands on all items. The prominent need was to motivate students learning science. To the contrary. their need for learning more about history and philosophy of science was the lowest. Veteran teachers and high school teachers had higher demands on designing evaluation items, but nonveteran teachers on evaluating the effectiveness of their instruction and updating their scientific knowledge. Teachers preferred the online education as a training method for most items except laboratory activities.

현재의 정보통신기술교육은 정보 활용적인 측면과 다른 교과에 대한 도구적인 성격이 짙다. 정보통신기술교육에 새로운 활력을 불어넣기 위하여 ACM과 IEEE의 공동보고서인 Computing Curricula 2003을 통하여 컴퓨터 교과에 대한 관점을 조명해 볼 필요가 있다. 컴퓨터 과학에 대한 내용학적인 접근을 통하여 교과에 대한 정체성이 확립되는 밑거름이 될 수 있다. 미래 사회의 주역인 학생들의 정보화 마인드 형성을 위하여 정보교육은 내용선정부터 체계적으로 시도되어져야 한다. 여러 분야 중에서도 컴퓨터 구조교육의 내용을 단순화, 정교화시키는 과정을 통해 정보에 쉽게 접근할 수 있고, 정보적인 사고가 가능할 수 있도록 프로토타입(Prototype)을 구성하고자 한다. 기존의 구조교육의 형태와 내용을 분석하여 학습 내용을 선정하여 요소를 추출하는데 그 목적이 있다.

This study is to distribute 5-year-old nuri curriculum science education contents in child picture books, and to investigate the categorical difference of science education contents between domestic and foreign picture books and among genres. The subjects were 219 picture books for children from 4 to 7, listed in which is published by Children's Book Study Group in 2012 and 2013. The research tool was from the article of 5-year-old nuri curriculum nature study, to analyze the contents of young children science education in the child picture books. Content analysis categories was set to two upper-categories and seven sub-categories. Research data were calculated in the analysis of the frequency and percentage of each item's category by the method of analysis conformity. In conclusion, first, in the analyzed result of the upper categories of young children science education contents in 219 picture books, the frequency appeared in order of 'Curious to maintain and expand', 'Learn living things and the natural environment', 'To explore the investigation technique', 'To enjoy the investigation technique', 'Utilize simple tools and machines', 'To search objects and materials', 'Learn natural phenomena'. Second, in the compared result between the domestic and foreign picture books and among genres, "scientific inquiry" is appeared more than "fostering an attitude of exploration".

The purpose of this study is to examine how online knowledge-based search service is being used by students in science education. Reviewing information and summarizing data are important parts in scientific inquiry. As more and more information is available online, how to review and summarize online information for scientific inquiry also becomes an issue. In this study, we examined one of the popular online knowledge-based search services to see what kinds of information in secondary school chemistry are mostly sought and how reliable those information could be. The result indicated that users mostly seek scientific explanations and problem solving but about 30% of provided information appeared to be incorrect. It implicates that it is necessary to pay attention for teaching students how to obtain, evaluate, and communicate online information in science education to enhance students' ability for scientific inquiry.

The purpose of this study is to analyze STS contents in the elementary school science textbooks developed under the 7th national curriculum. Major findings from the analyses are as follows: (1) The Percentage of STS contents included is 26% by the number of pages, and 40% by the lesson hour, Higher proportions of the STS contents are found in the domains of ‘energy’ and ‘material’. By grade level, the coverage of 5th grade textbooks is relatively low. (2) Most STS topics are related to science rather than technology or society. (3) In many cases, STS contents are used in the whole processes of a lesson. (4) Most activities are 'group activity' or 'experiment.observation'. There are few activities of 'role playing', 'spot study' or 'interview'. These results indicate that recent STS education trends are reflected on the revised textbooks well. However, it is suggested that some improvement is needed, such as diversification of topic or activity.
