This study analyzed the inquiry activities appearing in the astronomy sections of elementary, middle and highschool level science textbooks according to the five essential features of inquiry in the classroom as proposed by the National Science Education Standards (NRC, 2000), and SAPA (Science-A Process Approach). On the basis of this analysis, it is clear that the science textbook inquiry activities released the limitation to meet the goal of science education, namely scientific literacy, as it has been laid out by the 7th Science Educational Curriculum. This study revealed that the features of scientific inquiry which are most frequently used in the astronomy sections of science textbooks are 'data collection' and 'form explanation', whereas the features of 'oriented-question', 'evaluate explanations' and 'communicate and justify' rarely appeared. The analysis of inquiry activities by SAPA showed that the basic inquiry skills of 'observing', 'communicating' and 'manipulating materials' were used with increasing frequency according to grade level, and the integrated skills of 'investigating', 'creating models', 'interpreting data' and 'experimenting' were more emphasized in the textbooks. Therefore, it is suggested that students be provided with more opportunities to experience all the features of scientific inquiry and scientific processes as envisioned by the 7th Science Educational Curriculum in order to achieve the stated goal of scientific literacy. Science educators should be required to develop new lesson modules which will allow students to experience authentic scientific inquiry. It is crucial for science teachers to reflect upon and develop their understanding and teaching strategies regarding scientific inquiry through professional development programs in teacher education.

The purpose of this study is to investigate the educational validity of EBS education broadcasting. The purpose of science education is not only to improve metacognition, but also to make student acquire scientific knowledge. So, this study present the question of whether EBS education broadcasting could raise students' metacognition or not. At ㅂ highschool, the VOD texts provided by EBS education broadcasting was used for all curriculums including science in 2002 and 2003. It was accepted that the model wpuld be using considered VOD texts as materials and focusing on students' voluntary acting. But the students couldn't be given a stimulus raising metacognition by these models. The metacognition such as metaknowledge, metaexperience, and monitoring must be mediated during school hours for valuable science lessons. First, the manipulation such as teacher's pertinent question or comment reminding students about the materials was connected with teaming subject. Second, it is important for students to do an analogical experiment in odor to experience the reality. Third, feedback and the scripts of students' conversation must be given to students to monitor their own learning process.

This study is the analysis of interview with science major student about the effect of science club experience on career decision. The special interview was planned and arranged to meet students as well as their teacher. Both of the student whose background had experience in the science club activity, field science education during their high school days are majoring in physics and biology. In Summary: 1) science teacher's guidance deeply impressed the student that they respect the teacher as a occupational role model. 2) they really enjoyed the hands-on activities joyful. 3) their experience lasted so long time to keep them to stay in science field. 4) they had an experience of speaking before peer science club students who had similar interest and talent. We found the above four factors were really influential to encourage the subject to major in science career.

This research was executed in order to analyze the factors and strengths of learning difficulties that science-gifted high-school students experienced in Korea Science Academy. The subjects are 284 gifted high-school students from Korea Science Academy who responded to a paper-and-pencil questionnaire survey. The questionnaire used in this research was developed by focusing on the difficulties in the learning situations of science-gifted highschool students based on Rhodes' 4P theory of creative achievement. The data was analyzed using cross-tabulation analysis, frequency analysis, MANOVA by the SPSS 12.0 program. The analysis of the questionnaire survey on the learning difficulties showed (i) a grade difference in interpersonal relationship and (ii) gender differences in learning ability and learning strategies. Also, it was observed that the students tried to solve their learning difficulties most frequently by meeting their school peers except for methods of 'the others' such as relying on religious power.

In this study, we analyzed the relationship between the physical science domain of TIMSS 2019 and the Korean science curriculum. Twelve subjects are presented in the physical science domain of the TIMSS 2019 4th grade evaluation framework. Research group consisting of elementary and middle school teachers and science education experts, a total of 12, participated to analyze in which grade these subjects were included in the Korea 2009 revised and 2015 revised science curriculum. As a results of analyzing whether the achievement standards of the TIMSS 2019 evaluation framework and Korean science curriculum are consistent, the subjects pertinent to chemistry like 'chemical changes in everyday life,' 'heat transfer,' and 'electricity and simple electrical circuits' appeared not covered at all until the 4th grade curriculum in Korea. Given that the TIMSS 2019 evaluation framework is an international achievement standard, we are proposing to improve the Korean curriculum as follows: first, for the development of the next science curriculum, there is a need for science curriculum organized from the 1st grade of elementary school to connect the content and scope of chemistry in elementary, middle, and high schools as a whole including the Nuri curriculum. Second, as an alternative to the problem of suitability of learning volume and level of learning, it is possible to think of a method to readjust the grade of dealing with related concepts by lowering the difficulty or simplifying the concept. Third, it is necessary to discuss about introducing essential concepts and standard terms into Korea science curriculum according to international trends.

This study aimed to explore the saliences of formal school science and their influences on the attitude toward science communication through mass media. Saliences of school science are salient memories of school science which a perciever attends to selectively among various aspects of formal school science. Among saliences. external saliences refer to the sensory aspects of formal school science. and internal saliences refer to the observers' cognition. Attitude toward science communication through mass media constitute six scales; exposure. cognition. focus. belief. self perception of understanding. application. The questionnaire were developed and sample was selected by multi-stage stratified clustering. The sample size was 1,825. The data was analysed by correlation and multiple stepwise regression. Positive saliences were lab work and science teacher and negative saliences were lecture and exam/grade. According to the correlation and multiple stepwise regression analysis. saliences of the formal school science could account only a small part of the attitude toward science communication through mass media. Internal salieces could account the attitude toward science communication than external salience. Further studies on new models including attitude towards science are needed.

In this study, we analyzed science teachers' NOS-PCK in Science Inquiry Experiment lessons. Four science teachers in charge of Science Inquiry Experiment in high schools located in the Seoul metropolitan area participated in the study. NOS Lessons were observed, all of the teaching-learning materials were collected, and semi-structured interviews were conducted. All the collected data were analyzed according to five factors of NOS-PCK. As a result of the study, their understanding and consideration of the curriculum related to NOS were insufficient in some cases. They thought that given inquiry activities or textbook composition was not effective for NOS teaching so that they actively reconstructed the curriculum. In terms of teaching strategies, their lessons were close to explicit approaches. However reflective approaches were generally lacking. They were neglected in evaluating NOS for reasons that views of NOS are individually subjective or that NOS is not an area of cognitive learning. They guessed the state of students by relying on their own experiences rather than based on evaluation results. They recognized a specific aspect of values of NOS learning. And intention to teach NOS played an important role throughout their classes. Based on the above results, we discuss some ways to improve the professionalism of science teachers for NOS teaching.

Curriculum content interest has been studied in terms of teachers rather than students in ways that help revise curriculum and develop textbooks. In this study, 227 first-year high school students were interested in what they learned in middle school and what they learned in high school, focusing on meaningful assumptions and contents for middle school and high school students. We analyze this difference in interest by gender and achievement level. According to the research results, first-year high school students, who are in the middle and high school transition period, have relatively high interest in themselves, such as youth development, compared to family needs or interest in family life. There were no gender differences, but there were differences in content interest depending on the level of achievement. This means that the content interest should be interpreted by considering various variables such as the development of learners, the situation of learners in the school-level transition period, and the entrance examination of universities. The results of this study will provide implications for future curriculum revisions, textbook development, and curriculum considerations, and will need to be carefully analyzed and utilized based on a learner-centered perspective.

Research-based professional development is essential for in-service and pre-service science teachers across the nation. The purpose of this study was to examine in-service science teachers' and pre-service teachers' perception of the training program for professional development using advanced science laboratory equipment and experiments. Science teachers (N= 43) in science high schools and pre-service science teachers (N=189) were selected as research subjects. As a result of this study, in-service teachers and pre-service teachers recognized that they lacked understanding and experience in advanced science laboratory equipment, although they perceived the importance of its use. They wanted to attend training programs during vacation if they would have the opportunity. Both groups felt that they needed to improve their ability to operate the advanced science lab equipment, preferring to practice these instruments in the training programs. In-service teachers preferred the development of teaching and learning programs for use of the advanced science laboratory equipment. However, pre-service teachers preferred using the advanced science laboratory equipment. The study gives implications for teachers' professional development.
