The purpose of this study was to develop a scientific inquiry model that makes scientific inquiry accessible to science teachers as well as students. To develop a scientific inquiry model, we investigated the research process demonstrated by ten scientists who were working at academic research institutions or industrial research institutions. We collected data through scientists' journal articles, lab meetings and seminars, and observation of their inquiry process. After we analyzed the scientists' inquiry strategies and processes of inquiry, we finally developed the Scientist's Methodology of Investigation Process model named SMIP. The SMIP model consists of four domains, 15 stages, and link questions, such as "if, why", and "how". The SMIP model stressed that inquiry process is a selective process rather than a linear or a circular process. Overall, these findings can have implication science educators in their attempt to design instruction to improve the scientific inquiry process.

This study aimed to develop and apply the process-focused assessment, and verify the assessment's effectiveness for improving scientific communication skills in elementary science learning. To achieve the aims of this study, the unit "Action of Electricity" in elementary science text book for 5-6th students was selected, and then 13 process-focused assessments were developed to improve scientific communication skills. 119 elementary school students in 6th grade participated in this research. it was performed to compare between 60 students on the general assessment and 59 students on the process-focused assessment in the results of achievement levels on scientific concept and scientific communication skills. The results were as follows: First, this study showed that process-focused assessment had higher educational effectiveness in specific area of scientific communication skills than the general assessment. Second, the process-focused assessment can help to form students' scientific concepts as the general assessment. Furthermore, the process-focused assessment group was more effective at reducing the non-scientific concept than the general assessment.

The purpose of this study is to examine the effect of PBL-based astronomical observation on the science process skills and scientific attitudes in elementary science-gifted students. To verify research problems, the subjects of this study were forth-grade students selected from one classes of an elementary science-gifted class in Busan National University of education : the research group is composed of twenty students who were participated in PBL-based astronomical observation program. During four weeks, the PBL-based astronomical observation program instruction was executed in the reasearch group. Post-test showed following results: First, the research group showed a significant improvement in the science process skill. We look into detailly this, the research group showed a significant improvement in the basis science skill. The sub-factor 'expectation' of the science process skill effects a significant improvement. Second, the research group showed a significant improvement in the scientific attitudes. In conclusion, PBL-based astronomical observation program was more effective on science process skill and scientific attitudes. However, since the study has a limit on an object of the study and the applied program, the additional studies need to be conducted with an extended comparative group and program.

The purpose of this study was to examine the effect of scientific discussion classes focusing problem finding on the primary school students' scientific creative problem solving ability, science process skills and attitude toward science class. To verify this research problem, the subject of this study was fifth-grade students selected from four classes of M elementary school located in Busan city. For four months, the experimental group of 51 students was taught using the "scientific discussion classes focusing problem finding". The control group also of 53 students was taught in normal classes which used a text-book. All students were given pre and post test to verify the effects of scientific discussion classes focusing problem finding on the primary school students' scientific creative problem solving ability, science process skills and attitude toward science class. The results from this study are as the following. First, the scientific discussion classes focusing problem finding were effective in scientific creative problem solving ability among the primary school students. It is possibly because in the process where one student compare his/her own thoughts with the others' ones and discuss them. Second, the scientific discussion classes focusing problem finding were effective in science process skills among the primary school students. Third, the scientific discussion classes focusing problem finding were effective in attitude toward science class. In conclusion, the scientific discussion classes focusing problem finding had positive effects on improvement of primary school students' scientific creative problem solving ability, science process skills and also could lead to a change in students' cognition about science class to a positive way. Therefore, the scientific discussion class focusing problem finding is hopefully to be provided as an effective instructive strategy of science class in school in the future.

This research examined age differences in the way 3-, 4-, 5-year-old children solve scientific problems involving magnetic and nonmagnetic objects. Their scientific process skills and scientific concepts were examined in 1) hypothesis setting, 2) hypothesis verification and 3) hypothesis application. Data was analyzed by one-way and two-way ANOVA and Scheffe. Children's scientific process skill presented differences by age in each phase of problem solving. That is, the scientific concept level demonstrated by 4-year-olds was higher than that of the 3-year-olds. That of the 5-year-olds was higher than the 4-year-olds. In addition, in all age groups, the children showed a higher level of understanding about magnetic and non-magnetic objects in the hypothesis application phase than in the hypothesis setting phase.

Micro-cell LC film and polymer network liquid crystal (PNLC) film by using continuous compatible process have been developed . A high-contrast micro-cell LC film has a strong potential as a high-performance flexible device. PNLC film has the low driving voltage. Both films show the characteristics of lightness, thinness and mechanical stability.

본 연구는 IIM을 적용한 천문학습 프로그램 개발 적용이 초등과학영재학생의 과학탐구능력 및 과학적 태도에 미치는 효과를 알아보기 위해 수행되었다. IIM이란 독자적 탐구방법으로 학생들 스스로 탐구하고 연구하는 수업형태로 7단계의 학습단계를 가지고 있다. 본 연구의 실행을 위해서 초등학교 과학교과 5학년 천문영역의 내용을 바탕으로 IIM의 탐구단계를 적용하여 총 7차시(6주간)로 천문학습 프로그램을 구성하였으며, 주제 선정하기(1차시), 목표 설정하기(2차시), 자료 조사하기(3차시), 탐구 활동하기(4차시), 목표 평가하기(5차시), 보고서 작성하기(6차시), 발표하기(7차시) 등으로 구성하여 적용하였다. 본 연구의 효과를 검증하기 위해 연구반은 울산광역시 소재 G 초등학교 과학영재반(초등 3학년) 20명을 선정하였다. 검사도구는 과학탐구능력 검사와 과학적 태도 검사지를 사용하였고, 통계해석 프로그램은 SPSS WIN 18.0을 사용하여 결과를 분석하였다. 연구의 결과는 IIM을 적용한 천문학습 프로그램은 초등과학영재학생의 과학탐구능력(F=4.920, p=.021)에 긍정적인 효과가 있었고, 초등과학영재학생의 과학적 태도(F=11.224, p=.001)에도 긍정적인 효과가 있었다. 본 연구를 통해 IIM을 적용한 천문학습 프로그램은 초등과학영재학생들의 과학탐구능력 신장과 과학적 태도 함양에 도움이 된다는 것을 알 수 있으며 나아가 과학영재원이나 과학영재학급 교육과정에 기여할 수 있을 것이다.

While most previous studies have developed educational programs for science gifted children and have analyzed the differences between science gifted children and ordinary children using quantitative research methods, few have investigated the differences among the science gifted, especially in terms of the scientific thinking process. The present study was conducted to explore the thinking characteristics of the elementary science gifted according to the three scientific thinking process types during the scientific problem solving process. The study resulted in the collected of quantitative and qualitative data through tests and an interview with questions and scientific problems which required the use of one of the three scientific thinking processes. Ten elementary science gifted children served as interviewees. Two types as an opistemological basis for solving the problems are revealed on inductive thinking problems. Three types are on abductive thinking, and Three or Four types are on deductive. The results are expected to have an influence on the teaching and the evaluation of the elementary science gifted.
