  • 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 objective of this study was to review the meaning and problems of Scientific Knowledge and Ethical Value in Environmental Education. The ultimate goal of environmental education is shaping proenvironmental human behavior. The factors of human behavioral decision making are ideology, value, attitude and behavioral intentions. Ideology is a kind of belief system used by social groups to interpret their social world. The main elements of belief system are knowledge and value. The traditional thinking in education has been that we can change behavior by making human beings more knowledgeable and more valuable. In environmental education, the aim of scientific inquiry is to analysis cause-effect relation of human beings behavior and environmental phenomenon, and ethical education is to change the mind of human beings from zero-sum to positive-sum about the relations between human beings and natural environments. But, there are many problems of knowledge education and value education in environmental education. For example scientific knowledge without ethical value is dangerous to environment protection, and ethical value without scientific knowledge is vague. Therefore, we must recognize that the relationship of ethical value and scientific knowledge is not substitutional but complementary. The teaching-learning methods which can integrate knowledge and value in environmental education are rational decision making model. For this model, we can construct teaching contents with inquiry materials. To earn the benefits of specialization among several subjects in environmental education, social studies can focus on social science knowledge and decision making, science education can focus on pure natural science knowledge and scientific investigation, moral education can focus on problems of ethical value system, home economics can focus on practical action and environmental education(Environments in middle school, Ecology and Environments in high school) can integrate social-national science knowledge and ethical value in broad perspective about human beings and ecosystem. That is the method to protect from law of diminishing marginal utility of learning in environmental education.

  • Prior research has reported that student epistemological beliefs might affect their participation in learning and the process of conceptual change. The purposes of this study were to investigate the characteristics of sixth grade students epistemological beliefs about science and the relation between their epistemological beliefs about science and factors related their learning. For this research questions, 245 sixth grade students participated and various test instruments were used in this study. Students answered two types of questionnaires on epistemological beliefs about science and three test instruments on factors related students' learning(achievement in science, science inquiry skills, and cognitive levels). The results of this study were as follows. First, a large number of elementary school students believed that the purpose of science to perform activities like simple experiments. A lot of students believed that scientific knowledge was changeable according to the nature of scientific knowledge and that scientific knowledge could be learnt on their own. Also, many students believed experiment results to be basis on which to form personal scientific conceptions. Second, students who believed in more modern epistemology about science represented higher levels of science learning achievement, science inquiry skills, and cognitive levels. Therefore, when developing science curriculum, science educators need to consider how to develop student modern epistemological beliefs about science.

  • The purpose of this study was to develop 'Science History Based Chemist Inquiry Program' for the science-gifted in high school and investigated the application effects on the understanding toward the nature of science, scientific attitudes, and science career orientation. This study was conducted with one class of 17 scientifically gifted high school students, and the 'Science History Based Chemist Inquiry Program' was applied during 22 class hours. The results of this study were as follows: First, the science gifted students' understanding toward the nature of science showed a statistically significant improvement (approximate significance probability .005). Property of the scientific model, sub-domain of the nature of science, is significantly improved (approximate significance probability .029). This result show that 'Science History Based Chemist Inquiry Program' can improve the scientifically gifted high school students' perception about nature of science. Second, the scientifically gifted students' scientific attitude wasn't changed significantly. However, the openness and creativity in the sub-domains of the scientific attitude showed a statistically significant improvement (p<.05). Third, science career orientation of science-gifted did not show a statistically significant change. But the value of the level of awareness about the science career has been significantly improved (p<.05).

  • In this study, we investigated how 'Scientific Inquiry Experiment,' a newly introduced subject under the 2015 revised curriculum, was implemented to identify the difficulties that science teachers face in the process of teaching the subject and to explore how to support them through online survey and interview methods. A questionnaire of the survey, which consisted of environmental factors of class, preparation and execution of class, teacher self-evaluation of class, and direction for the subject, was developed, and the online survey was requested with a response from one teacher per school from 1674 high schools nationwide. We analyzed the results from 814 teachers who answered all required questions, and we also conducted interviews and online advisory discussions to ensure the validity of our analysis. In the results of the study, teachers complained of lack of time for preparation and execution of the subject, and they demanded laboratory assistants and quality teaching materials. In addition, in order to achieve the goal of the subject, they agreed the necessity of using the 'block scheduling' though they also agreed the difficulties of its implementation. Meanwhile, the alteration of guidelines for evaluation, which was changed from 9-grade system to 3-grade system, was positively recognized by teachers. As a result of this change, the percentage of performance assessment increased in 2019 compared to 2018, but there were no significant changes in the number of 'hands-on activity.' Finally, we proposed ways to support 'scientific inquiry experiment'.

  • This study was to analyze science process skills related to 'state of matter' and 'state change of matter' in the kindergarten, elementary and middle school science textbooks. On the base of articulation, we analyzed science textbooks of the 5th kindergarten curriculum, the 6th elementary school science curriculum and the 6th middle school science curriculum. The findings indicated that the scientific inquiry abilities of predicting, classifying, hypothesizing and designing investigations are not enough in all grade science textbooks. Also, while young children have measuring ability theoretically, it was represented only in high grade textbooks. We concluded that these were inappropriate from the viewpoint of articulation which is related to scientific inquiry ability.

  • The purpose of this study is to develop cognitive scaffolding tools and to explore their effects on integrated science process skills of high school students. For this purpose, we developed cognitive scaffolding tools including one kind of classroom instruction for training integrated process skills and two kinds of individual learning materials that students can selectively study according to their level of inquiry ability. In addition, we developed hypothetico-deductive inquiry tasks as a tool to investigate the level of students on the integrated process skills for pre-test and post-test respectively. In order to verify the effectiveness of the cognitive scaffolding tools, we conducted inferential statistics on the pre-and post-tests of the experimental group and control group to examine statistical significance of students' inquiry level change depending on the usage of the cognitive scaffolding tools. We also produced Wrightmaps based on Rasch model to compare the change of inquiry ability depending on usage of the cognitive scaffolding tools. As a result, the experimental group using the cognitive scaffolding tools showed a significantly higher scores in all the components of integrated process skills namely, designing inquiry, collecting data, analyzing data, and forming conclusion than the control group. In addition, students who used cognitive scaffolding tools improved their inquiry ability and showed a distinct transition to higher level in each component of the integrated process skills. The results of this study suggest that high school students need cognitive scaffolding to alleviate or eliminate the functional barriers they face in conducting scientific inquiries.

  • The purpose of this study is to quantitatively and qualitatively analyze the science journals written by pre-service elementary school teachers, and to categorize the view on the nature of science and the process of their change. For this purpose, 112 science journals written by 13 pre-service elementary school teachers were analyzed. The frequency of each area was analyzed using the research framework of the four areas of the nature of science, and the pattern of change in perspective on the nature of science was inductively derived and classified using the VNOS-C test analysis framework. As a result, The nature of scientific thinking, nature of scientific knowledge, nature of STS, and nature of scientific inquiry were described in relatively similar proportions, but among them, The nature of scientific thinking appeared in the largest percentage, and the nature of scientific inquiry was described in the smallest percentage. The variability of scientific knowledge, the importance of empirical evidence, and the positive and negative effects of science were especially intensively addressed. In addition, the changing aspects of pre-service elementary school teachers' perspectives on the nature of science could be categorized into 'naive view maintenance type', 'informed view maintenance type', 'regression type', 'development type', and 'mixed type'. The element of 'the empirical nature of scientific knowledge' showed various patterns of change depending on the students, and most of the students maintained a informed view on the tentativeness of scientific knowledge for several sessions.

  • The purpose of this research is to find the effect of the lesson using open-inquiry report Lubric on open-inquiry standard and science process skill; to find the change of cognition on open-inquiry for elementary school 5th grade students. Two classes (elementary school 5th grade) were selected which located in a small and medium-sized city for this research and they were separated as an experimental group and a comparative group. Open-inquiry lesson was done by referring teaching method which introduced through the curriculum. The procedure was understanding about open-inquiry, making open-inquiry subject, planning, and performing inquiry, mid-term, performing inquiry, making a report, presentation, and evaluation. Open-inquiry report Lubric which developed by Sook-Kyung Kim et al. (2010) was provided to the experimental group. Comparative group was instructed by using open-inquiry report which introduced to the elementary school 5th grade science text book. Interview paper was developed in order to check out the effect of the research by using a test paper of science process skill. The following could be found out through the research. After open-inquiry lesson, 10 open-inquiry reports(5 reports from experimental group, 5 reports from comparative group) have been drawn at random as samples from the total 62 sets (30 reports from experimental group, 32 reports from comparative group) and evaluated by a researcher and two elementary school teachers who have master degree. The reliability of the 3 scorers was 0.923 of mean correlation coefficient. And then the researcher evaluated all open-inquiry reports. The average score of open-inquiry report was 66.78 for experimental group, 54.27 for comparative group, respectively. And there was a significant difference at p<0.05 level as a result of the t-test. The experimental group rated high at p<0.05 level according to the analysis of post-science process skill test. According to the result of survey, both experimental group and comparative group had understood open-inquiry activity. It was especially rated high for experimental group on understanding scientific inquiry process, interest and satisfaction in open-inquiry and re-participation rate. By interviewing experimental group, it is recognized that the students utilized Lubric very well through the overall process. Finally, self-evaluation was done during open-inquiry activity and it was reported that the students gained more knowledge about science and changed to positive about science. As a result, the lesson using open-inquiry report Lubric was effective for students to improve writing skill of an open-inquiry report and science process skill and finally changed the cognition to positive about open-inquiry lesson.
