The purpose of this research was to investigate science teachers' thoughts about hypotheses and rules related to the contents of ninth grade 'Construction of Matter' and 'Rules of Matter Change' chapters. The changes of their thoughts through experience of the abduction viewpoint were also analyzed. Twenty-two science teachers in the masters course took lessons and discussions related to the abduction viewpoint in the course of three weeks. The changes in thought of four teachers selected among them were investigated through individual interviews and their reports. From the investigation, it was found that the two teachers who had not recognized the problems of textbook content order could distinguish rules and hypotheses after the lessons and discussions. The two teachers who had recognized the problems before the lessons gained the abduction viewpoint through the lessons. They also recognized new opinions related to teaching styles for students and the meaning of the abduction viewpoint on education.

Purpose : This study was done to examine the actual effect of the scapular position in these flexibility tests. The purpose of this study was to examine the differences between the measurement of SRT(Sit-and-Reach Test) without intentional abduction of the scapular (pre-test) and with intentional abduction of the scapular (post-test). The hypothesis is: 1. There is no differences in the SRT result of the pre-test and the post-test. 2. There is no differences in the HJA(Hip Joint Angle) result of the pre-test and the post-test. 3. There is no differences in the Spine Motion Test(SMT) result of the pre-test and the post-test. Method : The total 60 people (30 men, 30 women) were participated in this study. In the pre-test, the subjects were asked to sit on the examination table and try the SRT motion; and then the HJA, SRT and the SMT numerical values were taken. In the post-test. the subjects were instructed to intentionally bring the scapula outward from the midline; and the HJA, SRT and the SMT numerical values were taken. Result : In the pre-test. the SRT result averaged 34.17cm. and in the post-test. the SRT result averaged 36.68cm. The difference was about 2.81cm which showed a significant mean statistically (p<0.01). The measurement increased by 8.22%. The HJA was $85.9^{\circ}$ in pre-test, and it was $85.5^{\circ}$ in post-test. giving the $0.4^{\circ}$ differences. Therefore, it didn't have a statistical mean (p>0.05). The SMT value was 69.56cm in the pre-test. and it was 69.28cm in the post-test, about 0.28cm decreased. Therefore, it didn't have a statistical mean (p>0.05). SRT values and HJA values were correlated (p<0.01). SMT values and SRT values (p<0.01), and SMT values and HJA values(p<0.05) were each in counter correlation. Conclusion : The result of the SRT without intentional scapular abduction (34.17cm) and with intentional scapular abduction (36.68cm) showed a significant increase about 8.22% (p<0.01). In SRT, the effect of the intentional scapular abduction on SMT showed no significant means, the pretest value being 69.56cm and the post-test value being 69.28cm (p>0.05).

The purpose of this study was to analyze abductive reasoning on the inquiry of scientists and elementary school gifted children in science. Subjects for this study were eight scientists and eight elementary school gifted children in science studying in the Academy of Gifted Child Education in Science affiliated with Seoul National University of Education. As a result, abductive reasoning on the scientific inquiry of scientists and gifted children showed the three stages of generating hypotheses, designing the experiments, and interpreting the results. The abductive reasoning in each stage characterized the five types as complex abduction, analogical abduction, observation-based abduction, logic-based abduction, selective abduction. The sub-reasoning process of the abductive reasoning of gifted children in science differed in some ways from that of scientists. First, for most scientists, representing a method or representing a casual explican appeared after searching for the characteristics of variables but for gifted children in science, searching for the characteristics of variables appeared after representing a method. Second, scientists tend to rely on logic-based abduction but gifted children in science tend to rely on observationbased abduction. Third, scientists reason by the similar rate in three steps: generating the hypothesis, designing the experience, interpreting the results. On the other hand, most gifted children in science reason about designing the experience.

Objectives : This study was conducted to understand 4 groups in tentatively named "muscle coordinative manipulation" by Korean medicine. Methods : We researched some articles on meridian-muscle theory and muscle's action that are classified into 4 groups in muscle coordinative manipulation. Results : The outcome of examining the hypothesis is as follows: 1. The 1st hypothesis : 'Elevated shoulder' group mainly consists of muscles that are involved with shoulder elevation, abduction and external rotation. 'Lowered shoulder' group is mainly composed of muscles that acts of shoulder depression, adduction and internal rotation. 'Elevated pelvis' & 'Lowered pelvis' groups didn't show significant features by the movement of the hips. 2. The 2nd hypothesis : Most of muscles in 'elevated & lowered shoulder' groups are classified into 'hand taiyang' meridian-muscle. Most of muscles in 'elevated pelvis' group are included in 'foot jueyin' meridian-muscle. Most of muscles in 'lowered pelvis' group are classified into 'foot taiyang & foot yangming' meridian-muscle. Conclusions : There is no significant classification in muscles that comprise 4 groups in muscle coordinative manipulation when it comes to meridian-muscle theory and muscle function. More studies on chain reaction of muscle and subsequent analysis in Korean medicine are needed.

Hypothesis is defined as a single proposition proposed as a possible explanation for the occurrence of some observed phenomena. The purpose of this study was to analyze and categorize hypotheses generated by students on the cause of difference between the structures of muscles of the fishes and the terrestrial animals. A hypothesis-generating test was administered to 23 three college students who were majoring in science education. The study showed that college students generated manipulative and theoretical hypotheses as proposed explanations for the structural difference between muscles of the fishes and the terrestrial animals. Furthermore, students generated several hypotheses which were categorized by the quality of abductive process based on the degree of likeness between experienced knowledge and current phenomena. This study also discusses the implications of these findings for teaching and research in science education.

This study aimed at public officials who are most strongly demanded to tear up the corruption and diagnosed what they really think about 'the corruption'. So, a qualitative research method called 'subjectivity study' or 'Q methodology' was used to typing on the perception of corruption. In other words, 30 Q-samples related to corruption and P-samples composed of 30 public officials were investigated to derive the analysis results. As a result of the analysis, three types of perceptions of corruption were defined. That is, showed a high distribution of civil servants such as 'educational administration' and 'teacher', and and showed a high distribution of 'general administrative positions' civil servants. Also, among the respondents of , it was found that the distribution of 'high' was higher for the level of corruption in our society, and the distribution of 'medium' for and was found in the case of the respondents with high factor weight. The overall explanatory power was high at 62.11%, and based on the series of results, a hypothesis could be found that 'the perception of corruption differs according to the characteristics of the work of public officials'. By the results, the commonly recognized terms for 'corruption' were 'politician/politician' and 'solicitation'. Therefore, based on a series of results, this study is expected to be the 'Priming' for finding ways to move toward a more transparent society by diagnosing and reflecting on the thoughts of corruption in our society once again.

The purpose of this study was to test the hypotheses that student's abductive reasoning ability plays an important role in hypothesis-generating about vapor condensation, and student's hypothesis-generating requires their causal explicans as well as experience. To test the hypotheses, the instruments of hypothesis-generation, prior knowledge, and experience with vapor condensation were developed and administered to 6th grade students. This study found that 72 subjects among 89 students who had prior knowledge about vapor condensation failed to apply their prior knowledge to hypothesis-generating about the vapor condensation. This result showed that the students' failure in hypothesis-generating was related to their deficiency in abductive reasoning ability. In addition, this study showed that 54 subjects among 56 students who had experience with vapor condensation also failed to generate hypotheses. This result supported that student's causal explanations were separated from their experience. Therefore, this study suggests that science education should include the teaching of abductive reasoning skills for developing student's hypothesis-generating skills.

Various research methods have been used in science depending on the various contexts. This implies that certain methods or inferences may be more frequently used in earth science. The purpose of the study are to explore the contexts of earth science, and the inferences frequently used in earth science. The context earth science research is quite different from that of other areas of natural science in terms of its time scale, space scale, accessibility, complexity, and controllability. The purpose of earth science research is twofold: historical and causal. The inferences frequently used in earth science are abduction and prediction. Abductive inferences go from the resulting state to controlling state. Predictive inferences go from hypothesis to expected data.

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.

The purpose of this study was to verify the effects of science classes using abductive strategies on the scientific concept understanding and meta-cognition. The subjects included two classes of sixth graders from K Elementary School in B Metropolitan City and they divided into two groups. Research group was composed of 21 students(10 boys, 11 girls) and comparative group was composed of 21 students(11 boys, 10 girls). In order to achieve aims of this study, proper contents to apply abductive strategies were selected from the first semester science curriculum for sixth graders. Also five-steps study papers were designed to elicit abductive reasoning. While the research group received 20 times of reframed science lessons using abductive strategies, the comparative group received common science lessons according to the teachers' manual. The results of this study are as follows. First, science classes using abductive strategies were effective for the scientific concept understanding. Also there were statistically significant differences between the research group and the comparative group in overall science sub-domain. In the process of hypothesis formulating, students tried to find out scientific causes thoroughly to present the optimal explanation and they concentrated on the analysis of each scientific concept. It is thought that this process contributed to better understanding in scientific concepts. Second, science classes using abductive strategies were effective for improving meta-cognition. There were statistically significant differences between the two groups and especially in monitoring that is one of sub-factors of meta-cognition. It indicates that hypothesis formulating process gave positive effect on meta-cognition by stimulating critical thinking and manifesting elaboration.
