This study was designed to 10 questions as development of GAP program for ninety high school students(each student of 30 with achievement as high, medium, and low categories), it was analyzed the perception of Earth scientist. High school students have a positive perception about a course in Earth science, but they have lack of knowledge about Earth scientist as a career man, and they can't recognize Earth scientist as a career. A failure of learning of Earth science for Students with low level achievement leads to a negative perception about Earth scientist and disconnection to future career. School education should provide an opportunity to encounter Earth scientist for students and it is badly in need of effort to connect to the job training program.

This study investigated that internalized images of earth scientist's work of 110 high school students who complete a course in Earth Science I through drawing. As a result that reflected the character of earth science as a school subject, it is shown that nearly half of the students believe that earth scientist's working place is outside. An object of study is limited to such areas as astronomy and geology, it says that students has little understanding of areas of atmospheric and oceanic sciences. There are lots of answers that tools for working are telescope or microscope, it reveals a huge difference between the results of advanced research that analyzed the typical experimental devices, and students realized that working is not invention but survey. We should try students to recognize earth scientist as a job with relation to their future.

The purpose of this study was to compare the processes of making hypotheses concerning the anomalous path of Wukong, a typhoon that came close to Korea recently, between an earth scientist and undergraduate students. Data were obtained through interviews with a practicing earth scientist as well as five undergraduate students. Inquiry reports of the students were also analysed. The result showed that while the earth scientist conducted a case study with already-established models of typhoon, the students were enabled to work on the specific case of Wukong only after they learned general theories on typhoons. Background knowledge played an important role for the scientist and students to formulate scientific hypotheses. Both the earth scientist and undergraduate students generate multiple working hypotheses, and they considered a couple of conditions to select more plausible hypotheses, including theoretical coherence, causative processes, and consistency with empirical data. Despite these similarities, there were differences in the scope and depth of background knowledge between the scientist and students. In addition, it was not likely that the undergraduate students possessed explicit perceptions of the conditions which could make a hypothesis more probable, except for the empirical consistency. Implications for science education and relevant research were discussed.

Through the systematic analysis on articles about the environment in newspapers, the news reports were considered as effective materials, so after being reconstructed, they were used as learning materials in a lesson on environment contamination which is newly introduced in Earth Science I from the 2009 curriculum revision. To examine students' attitude toward science, before and after NIE application to the students, Test of Science Related Attitudes(TOSRA) as a test tool was carried out which was composed of 7 categories - four optional questionnaires for each category, 28 in total were used. The result was as follows: in a pretest, based upon the average scores by factors the factors ranked from the highest to the lowest as follows: the social meaning of science, the acceptance of the scientific attitude, the commonness of a scientist, the attitude to scientific exploration, the pleasure in science class, the vocational interest in science, the concern over science as a hobby, and in posttest, their ranking as follows: the acceptance of the scientific attitude, the pleasure in science class, the commonness of a scientist, the social meaning of science, the attitude to scientific exploration, the vocational interest in science, the concern over science as a hobby. Also they were all statistically significant at a significant level p<0.05. However, the test revealed that there were some negative effects on the social meaning of science and the attitude to scientific exploration and therefore it is judged that in order to overcome those influences, some bright articles about solving the environment contamination should be applied to the lessons and be complemented effectively by experiments and various media: NIE as well as science magazines, data from Internet search and treatises on science.

The number of students choosing science, technology, engineering, and mathematics (STEM) related careers are declining. Thus it became a worldwide challenge in the $21^{st}$ century. As public images of the engineers are unfavorable and inaccurate, misconceptions and stereotypes about engineers are prevailing. The purpose of this study was to investigate elementary school students' perceived mental and pictorial images of engineers and the nature of engineering work. This study involved 512 fifth and sixth grade students (Boys: 287 and Girls: 225) from four elementary schools at one of metropolitans in South Korea. The Draw An Engineer-Korean version (DAE-K) was developed based on Draw an Engineer (DAE) and Draw a Scientist (DAS), and Song and Kim (1999)'s instruments. A pilot-tested was conducted with 33 elementary students prior to the main study. The students were asked to answer how they think the engineers would be, to draw an engineer at work, and to write the engineer's personal information and the job description. Engineers were perceived as a person fixing, building, manufacturing, working outdoors in labors' clothes such as a robe. Engineers were shown with building tools, robots, airplanes, machines, conveyor belt, etc. Moreover, compared to the scientists, engineers were perceived as less intelligent, less imaginative, and less accurate. The results of this study revealed that elementary school students had a lack of accurate images of engineers. Students' current perceived images of engineers could help educators find the baselines for the future engineering education in elementary schools. In addition, the findings of this study could also contribute to the development of engineering education in terms of gender issues, STEM career choice, and even cultural diversity.

The first accurate estimate of the Earth's circumference was made by the Hellenism scientist Eratosthenes (276-195 B.C.) in about 240 B.C. The simplicity and elegance of Eratosthenes' measurement of the circumference of the Earth by mathematics abstraction strategies were an excellent example of ancient Greek ingenuity. Eratosthenes's success was a triumph of logic and the scientific method, the method required that he assume that Sun was so far away that its light reached Earth along parallel lines. That assumption, however, should be supported by another set of measurements made by the ancient Hellenism, Aristarchus, namely, a rough measurement of the relative diameters and distances of the Sun and Moon. Eratosthenes formulated the simple proportional formula, by mathematic abstraction strategies based on perfect sphere and a simple mathematical rule as well as in the geometry in this world. The Earth must be a sphere by a logical and empirical argument of Aristotle, based on the Greek word symmetry including harmony and beauty of form. We discuss the justification of these three bold assumptions for mathematical abstraction of Eratosthenes's experiment for calculating the circumference of the Earth, and justifying all three assumptions from historical perspective for mathematics and science education. Also it is important that the simplicity about the measurement of the earth's circumstance at the history of science.

The purpose of this study wasto analyze the factors that enhance their learning achievement in a fieldtrip environment. For this academic goal, we analyzed a pattern of fieldtrip-related perception and attitudes of 19 science-talented students who participated in the 2007 KESO winter school. As for the perception type, the result of analysis showed that the science-talented students understood a fieldtrip as an experimental inquiry from an inquiry perspective, and that their understanding about a fieldtrip was based on anthropocentrism, positivism and instrumentalism from a science philosophy perspective. Regarding theattitudes type, the result revealed that the purpose of the winter school was mainly to learn knowledge in earth science, and that there was a significant tendency for the participating students to become a future scientist more eagerly than their parents expected. Students' fieldtrip-related academic self-concept was mostly positive while the participants experienced both positive and negative emotions.

The purpose of this study was to identify the scientists' abductive reasoning in three stages of hypothetical-deductive inquiry process; generating hypothesis, designing, and interpreting data and to suggest new analytic coding frames on abductive reasoning in each of the stages. For this purpose, the interview protocols collected through in-depth interviews with eight scientists were analyzed by the early frame with sub-elements derived from the literature reviews. The need of a new frame of analysis beyond the previously established elements arose from the result of this analysis because the processes of abductive reasoning were found in all three stages. Based on scientists' interview data, this study then designed a new frame of analytic coding frames on the abductive reasoning in each of the stages. The content validity index from four experts was 0.90, and these frames showed a good fit to analyze the scientists' real process of abduction in three stages of hypothetical-deductive inquiry process.
