The purpose of this study was to investigate the relationships between the pedagogical content knowledge in science teaching of pre-service early childhood teachers and their attitude toward science and science teaching efficacy belief. A total of 294 pre-service early childhood teachers responded to a questionnaire that examined their pedagogical content knowledge in science teaching, attitude toward science, and science teaching efficacy belief. The results of this study were as follows: First, teachers had average pedagogical content knowledge in science teaching. The groups of 3rd and 4th grades were significantly higher than the 2nd grade group. Second, the teachers' recognition was below average in attitude toward science and science teaching efficacy belief. The groups of 3rd and 4th grades were significantly higher than the 2nd grade group. Third, a meaningful statistical relationship was found between the pedagogical content knowledge in science teaching of pre-service early childhood teachers and their attitude toward science and science teaching efficacy belief. As the score of pre-service early childhood teachers in pedagogical content knowledge in science teaching became higher, the score in attitude toward science and science teaching efficacy belief became higher.

The purpose of this study was to investigate the effects of scientific program for gifted elementary students using metacognition on learning-flow and lingual interaction. For the purpose, the two classes for elementary science of P Institute for Gifted Education located in Pusan were assigned to experimental and control groups, respectively. The experimental and controls groups received eight sessions applying a program for scientifically gifted students using metacognition and same program without using it, respectively. The learning-flow test and the lingual interaction observed among students and between teacher and students pre and post program were compared and analyzed. The results shows that there was no significant difference between pretest and posttest in experimental group, indicating that learning-flow is not a construct obtained by short-term using of metacognition. For the lingual interactions, however, the amounts of conversation and the ratio of high level conversation in experimental group were 1.6 and 1.5 times higher than those in control group. This suggests that the lingual interaction may be varied among classes even with same experiments, by instruction method. The lingual interaction is not active in control group where the experimental results may be obtained easily only with sincere attitude while, in experimental group, questions using metacognition and providing intellectual stimulation is continuously presented, leading to high level of lingual interaction, therefore it is considered that the development of scientific program for gifted elementary students using these advantages is needed.

This study was to analyze the educational objectives of evaluation of practice quizzes and learning objectives of chemistry I textbooks for the 2009 revised curriculum by Klopfer's taxonomy. The result revealed that the objectives of science education indicated in the 2009 revised curriculum were contained the educational meaning of all categories except 'manual skills' of Klopfer's taxonomy of educational objectives. The learning objectives of chemistry I textbooks laid mostly on 'the knowledge and comprehension' and 'the process of scientific inquiry'. It showed that 'the objectives of scientific knowledge and methods', 'manual skills' and 'scientific attitude and interest', 'orientation' seemed to be taken in a relatively careless way. The result on the practice quizzes in textbooks, they also laid stress on 'the knowledge and comprehension' were covered much, even though they were emphasized in the other objectives of the curriculum. It was concluded that the educational objectives of the science textbooks did not reflect much on educational objectives of the 2009 revised curriculum.

Since 2010, in general hospital, they can install western medical post, traditional Korean medical post, and dental post. So the environment is made for the Cooperative medical system between traditional Korean medicine(TKM) and western medicine(WM) to be performed. So we found out about how doctors think about TKM and what is needed for TKM & WM cooperative system to work well. When we found out about how recognition changed about TKM during their medical school years and after they became doctors, positive answer increased from 25.6% to 30%, negative answer decreased from 41.9% to 32.0%, severely negative increased from 9.3% to 16%. They changed to positive about TKM after they became doctors. But severely negative also increased. The element they lose faith in TKM is their doubt about the scientific aspects of TKM. On the other hand, severely negative recognition was also raised. 73.8% of respondents thought the most effective treatment of TKM was for myalgia. 33.3% of them answered the chance to encounter TKM was the mass media, indicating its limitation. 60.5% of them considered major reason for negative evaluation of TKM is its non-scientific aspects and only 30.9% said TKM treatment could be recommended to patients at the hospital. Doctors in WM for recognition on TKM is mostly negative and major reason is its non-scientific aspects. As the solution to this problem, scientification of TKM is suggested through research projects. These connections must be resolved to smoothly work interdisciplinary system of TKM and WM.

Over the past 10 years, STEAM education uprises to address student's low interest in and self-concept in comparison with their academic achievement in science, reacquaintance to enter schools of natural sciences or engineering. However, There is a paucity of empirical evidence revealing values and necessities of STEAM education in school. The purpose of this investigation is to develop steam education program making and using hands on sensor to experience new technology in school, to apply the program to 110 fourth graders, and to study the effect of the program. Pre- and post-test was used to measure level of student's scientific interest and attitude, scientific problem solving ability, scientific creative problem solving ability, personality test for children, satisfaction of school life. In conclusion, the result show that STEAM education improve every domain of the measurements.

Improving of scientific inquiring ability is the major goal of current science curriculum, and the 6th science curriculum. But science educators consider that the existing textbooks and teaching manuals are insufficient to achieve this goal. For science teachers at teaching site to guide students efficiently in research work, development of teaching-learning programs is urgently demanded. Hypothesis Verification Learning Model(HVLM) was applied to classroom situation to improve ability of scientific inquiry in experiment teaching of middle school biology. The effects of the model were analyzed to suggest some approach method to reach the goal of science education in this study. The major results of this study are as following: 1. The students and teachers responded positively on this new learning model. an students were willing to participate in biology experiment and they said that to know what was unknown to them while exchanging ideas and opinions through the discussion, It was hard for teachers to instruct at the first time and it took much time for them to arrange materials ready, but it turned to be easier as time went on. 2. In science process skills, there was no significant difference statistically by new leaning model. Only the formulating a generalization or model showed significant difference statistically between the two groups. 3. For scientific attitude, experimental group did not show significant difference statistically between the two groups, but the experimental group showed statistically more significant positiveness in all areas afterwards than before. 4. In science achievement test, there was significantly higher than the control group. It is also analyzed that they remember the experiments in courses and results they planned and performed by themselves longer than these guided by teachers.

The purpose of this study was to examine whether or not they have been revised corresponding to the purpose of revision by making a comparative analysis of the content and illustration in the 6th and 7th primary science textbooks. The analysis of content was composed of knowledge, inquiry process and attitude. The analysis of illustrations was composed of the kinds of illustrations and the role of illustrations. The findings of this research were as follows: First, as a result of content analysis of the primary science textbooks in the 6th and the 7th national curriculum, the ratio of inquiry process showed the highest frequency, next knowledge and lastly scientific attitude. And the 7th textbooks are greatly emphasized knowledge and science attitude. Second, as a results of the illustration analysis are as follows: There are conspicuous differences in that the illustration number of the 7th science textbooks Is about twice the illustration number of the 6th science textbooks and next, they place more weights on pictures and comics hard to discovery in the 6th science textbooks. Therefore, they have tried to induce the interests of students and heighten their understanding by supplementing the role of illustration presented as picture-centered and increasing its number presented as picture. In the results, although they have improved the problems of the 6th national curriculum a lot through the innovation including the interest induction of pupils through comics, the development of its content presentation method, the gradual change of subject number and the cultivation of curriculum according to the level of enrichment and supplementing types, the 7th science textbooks have fallen short of 6.3%, not around 30% in terms of the reduction in the 7th national curriculum. Accordingly, the 7th science textbooks also can be pointed out to have the problems of too much amount of studying compared to the time per week like the 6th science textbooks.

Since open inquiry of science was formally introduced at the 2007 Revised Science Curriculum Course, the purpose and effect of it has been positively evaluated, and it is underlined continuously until the revised science education course in 2015. However, through many previous studies, there is still a lack of awareness of open inquiry of both students and teachers in the field, and it was revealed they are continually appealing confusion and difficulties. Therefore, in this research, we analyzed the causes that make it difficult to execute open inquiry, and developed differentiated open inquiry guide materials that can contribute to the realization of teachers and students. They were developed by the brain-based evolutionary approach to provide students with authentic science. The brain-based evolutionary approach is reflecting the evolutionary attributes and the brain functions associated activities of scientists. It was revealed that, in the same way as the pilot test results, the usefulness of the differentiated guide materials were very high, and there was a statistically significant difference in the science attitude. It was found that the application of the brain-based evolutionary approach had positively influenced the stage of determining the inquiry themes, and self-confidence that could be able to do as a scientist. Analysis of top and sub group types on the basis of inquiry ability showed that both groups are improved at science attitude by the differentiated guide materials. There was a positive effect on change in the self-perception of scientific creativity. We were able to see a positive change in the post survey for open inquiry-efficacy. The developed differentiated open inquiry guide materials contributed to the improvement of open inquiry-efficacy for both the teacher and student.

The purpose of this study is to develop teaching program which utilizes emotional intelligence elements as a measure to stimulate the motive and scientific attitude of learners and examine the effect of its application. The target unit for this study is 'world of plants' in the fourth grade of elementary school, and the teaching program is composed of 3 stages including I(encounter with myself), S(encounter with science), and U(encounter with friends). The teaching program is organized in the way to reflect 5 emotional intelligence elements including self-awareness, self-regulation, self-motivation, sympathy, and personal relations properly according to each stage of teaching program. The result of applying this program into actual classrooms is as follows. First, it is proven that the teaching program actually helps improving the motive of learners to study science. The emotional intelligence takes a role of positive motive for thinking, and the learners monitor their emotion and behavior patterns by using a mirror notebook to reduce their anxiety about science. Second, it is proven that the teaching program changes the science related attitude of learners positively. The emotional intelligence elements help the learners to create friendly feeling toward science subject and have a friendly attitude toward science and a sense of expectancy to science class. Third, it is proven that the teaching program contributes to the improvement of learners' science study achievement. The emotional intelligence takes an important role in improving the learners' science study achievement through the role of adjusting and controlling the recognition capability. However, emphasizing the emotional intelligence excessively also has a risk to break the balance between emotion and recognition, so it is considered that the balanced approach should be applied.

This study is a survey conducted to explore what art high school students specifically see as nature of science. Third-year students of a high school of arts in Gyeonggi-do participated in the survey. The questionnaire was classified into three categories - the formative arts in the fine arts, the sound arts in music, the performing arts in dance, and drama and play. The study analyzed what they think of as similar aspects of science and art respectively according to their majors, with focus on the extracts. As a result, they mentioned 'creative imagination', 'correlation with technology', 'social and cultural relation', 'subjectivity', 'variability', and 'inquiring attitude' as similarities between science and art. The results are almost the same as the elements of the nature of science as agreed on by scientists. From the result, we can assume that students majoring in art, indeed, need an education on the nature of science. Also, while the fine arts students have more tendency to perceive inquiring attitude than others, music students are more likely to perceive variability than others. Therefore, teaching strategy in experimental inquiring context for the former is more helpful in understanding the nature of science, and teaching strategy in the context of scientific history for the latter.
