The purpose of this study is to identify the types and characteristics of the integrative thinking that learners with diverse learning backgrounds use in solving earth science problems. Four students in middle school were surveyed using questionnaires to know students' science learning background and test items with integrated content. A total of 200 items, 40 integrated items and 160 general items, were administered ten times. The students did not show a consistent relationship in terms of correct answer percentage in general items and that of in integrated items. In order to understand the type of integrative thinking of each student, after students solve an item, we analyzed the percentage of correct answers by types and interviewed them and analyzed the contents to identify the characteristics of the thinking used in solving each item. As a result, the types of integrative thinking used in problem solving were classified into three types, knowledge-based, real life-based, and integrated inquiry-based types. It is necessary to study various ways to improve the integrative thinking ability considering the characteristics of students in science teaching and learning.

The purpose of this study is to develop an astronomical observing education program that enables high school students to inquire the distance of astronomical bodies based on the research methods (observing open clusters and exploring collected big data) using small telescopes and DSLR cameras. After analyzing the 2015 revised science curriculum, we developed science club activity materials and teacher-student learning contents suitable for high school earth science education. A panel of six teachers and researchers of earth science education and astronomy, participated in developing the educational materials. The validity of the program was verified through establishing the agreement among the panels after in-depth discussions and clarifications. The program, developed with 10 lessons in total, showed high satisfactory content validity (CVI, .89) and conformity of school class (Likert's 5 point scales, 4.17). The feedback of the panels and the Delphi analysis continued to improve the quality of the program. The pilot testing result with high school students (N=9) showed that the students' satisfaction rate was high as 4.48. Using the astronomical observational education program of this study is expected to contribute in improving the convergence educational activity, interest, curiosity, and inquiry ability of students in the universe and the astronomical bodies.

The purpose of the study was to compare science curriculum documents of the several countries including Korea, the United States, the United Kingdom, Japan, and Singapore. The comparison focused on goals and contents in science education of each country. The goals for science education in each country were very similar. They included understanding knowledge, acquiring inquiry skills, developing positive attitudes towards science, and appreciating S-T-S in most countries. But each country's goal setting level was different; some countries set the same goals for several grades and other countries set different goals for each grade. Goals provided for each grade were more specific and elaborated. Science contents were categorized differently in each country. In Korea, science contents were categorized in energy, matter, living things, and earth. On the other hand, science contents were composed of 8 categories including unifying concepts and processes in science, science as inquiry, physical science, life science, earth and space science, science and technology, science in personal and social perspectives, and history and nature of science in the United States. In the United Kingdom, science enquiry, life processes and living things, materials and their properties, and physical process were categories for science contents. In Singapore, science contents were organized by themes relevant to students' everyday experience. Implications for goals and contents in science education to prepare students to live and work in a future society were suggested based on the results of the study.

The purpose of this study is to investigate the effect of science classes using elementary school distance science classes on science academic achievement and creative personality. The research group and non-research group were selected for 6th grade elementary school students. After 10 weeks of experimental treatment, science classes were conducted with the contents of the elementary school science section, 'Changes of the seasons'. In the three domains of 'knowledge', 'inquiry', and 'attitude', which are sub-domains of science academic achievement, as a result of the pre-post test, there was a positive effect in 'inquiry' and 'attitude', which are sub-domains of science academic achievement. However, it was found that there was no positive effect in 'knowledge', a sub-domain of academic achievement. However, it was found that there was a positive effect in the overall test result of academic achievement. Therefore, it is interpreted that science classes using elementary school distance science classes had an effect on academic achievement. There was a significant effect in the sub-domains of the creative personality test, 'persistence/obsession', 'self-confidence', 'humor', 'imagination', 'openness', 'adventure', and 'independence'. However, it was found that there was no effect in the sub-domain 'curiosity'. The overall test results of the creative personality test showed a significant effect. Therefore, it is interpreted that science classes using elementary school distance science classes are effective in cultivating creative personality. Students' perceptions of science classes using elementary school distance science classes also showed positive responses.

In this study, we investigated and compared the standard of the present teaching tools & facilities in 16 cities and provinces. On the basis of this data, we suggested the standard of teaching tools & facilities according to the new curriculum. In the analysis of the present teaching tools & facilities, we divided the scope of facilities into 'the common one' and 'lab & practical room[common].' This study made it possible to easily recognize a facility by deleting a prep room from the names of facilities. Also, we prepared the standard plan for teaching tools by putting its focus on how to desirably manage the curriculum while giving the independence of a school to the maximum because of all sorts & great numbers of teaching tools.

The International Astronomy Olympiad (IAO) was established by the Euro-Asian Astronomical Society in order to disseminate astronomical knowledge, promote international cooperation in astronomical education area and recognize the importance of astronomy in far-reaching field of science and human culture. The first IAO competition was held at the Special Astrophysical Observatory of the Russian Academy of Sciences located in the north Caucasus of Russia in 1996. Since then, it has been held every year. This paper describes the present status of the IAO main regulations regarding its operation and major results by year, related institutions, and organizations. We created a scientific inquiry framework to analyze past IAO problems in the recognitive aspect in order to measure levels of the scientific knowledges and the scientific thinking abilities. Through this analysis, we can understand the current status of the IAO, and examine the future direction of Korea Astronomy Olympiad. Also, we can make preparation for the IAO competition and the education of delegates.

The Ministry of Education established the plan to adopt a new college enterance examination system, so called Scholastic Ability Test for college, from 1994. The National Board of Educational Evaluation had carried out 7 experimental trials for the new examination system. Eventhough, the governmental officials advertised the purpose and characteristics of the new examination system, many students and parents did not understand the essential point very well. In this study the researcher tried to analyze the 7 trial examination items and the first Scholastic Ability Test for college carried out 1993. In this study, the researcher tried to find out all the items appeared in the 7 trials. In the analysis, all the individual items from the 1st trial to the 7th trial were used. The research results showed that the items were evenly distributed in all the four areas(Physics, Chemistry, Biology and Earth Science) of science content; however, they were heavily concentrated on data or information analysis categoris in the inquiry domain. In the domain of context, laboratory context was the major item context. The scores were also analyzed. The results showed that no significant difference between male and female students. However, science track students showed higher achievement scores than the non-science track student. The examination result showed high correlation with the tests routinely have carried out in schools. The over all analysis showed the new examination system showed very different characteristics to the conventional tests. Therefore, for the student to get successful result in the Scholastic Ability Test, they should change the way of study. They should try to understand scientific concepts rather than to memorize them. They should invest their time to carry out real experiments rather than to focus on the princples and laws of science. One of the most important thing would be for the student to apply what they learned to real life situations.

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 study was to investigate the characteristics of evidence-based reasoning practiced by middle school gifted students. Data were collected through an online task in which middle school students in gifted education institutes of a university located in the metropolitan area, Korea, performed inquiry about the shape of a planet's orbit. The students were given data of Mercury's greatest elongations and asked to draw the planet's orbit with the data. Each of the students was also asked to provide his or her hypothesis of Mercury's orbit before the drawing and to reason about the orbit again using his or her own drawing as evidence. The content analysis of the students' reports revealed 5 different types of judgement about the shape of Mercury's orbit, 4 types of reasoning about the hypothesis and evidence, and the characteristics of evidence-based reasoning within the judgement types. Based upon the analysis results, the importance of proper interpretations of evidence in evidence-based reasoning, the core role of the theory-evidence coordination, and the usefulness of working with multiple hypotheses were discussed. In addition, implications for earth science education were suggested.
