The purpose of this study was to investigate teaching anxiety and the professional development of beginning secondary science teachers. For this study, a survey was conducted among beginning science teachers (N=83) with under five years of experience, and in-depth interviews with these five teachers were carried out. The survey tackled beginning secondary science teachers' anxiety levels by asking about their difficulties in teaching science classes, and results showed that the teachers' levels of teaching anxiety marked high. Levels of teaching anxiety in physics among subjects and in chemistry among experiments marked highest. To overcome teaching anxiety, teachers searched for information on the Internet or received help from their colleagues and veteran teachers. They revealed that plans for professional development as science teachers included receiving in-service training and joining teacher communities. In addition, the best type of required training program for professional development appeared to be lectures about teaching know-how from veteran teachers.

The purpose of this study was to develop elementary students' ability to generate hypothesis knowledge through knowledge generation learning in science. The learning program consisted of a series of 28 activities to generate hypotheses in science. Eighty 6th grade students participated in the study and were divided into experimental and control groups. The experimental group was administered a program geared towards hypothesis generation learning and the control group was administered a program aimed at hypothesis expository learning in elementary science. After using the respective programs, subjects in both groups were tested in terms of their abilities in abductive knowledge generation and administered a descriptive self-report regarding their generation of hypotheses. Two of the 28 activity program worksheets in the experimental group were analyzed in terms of the quality and process of students' hypothesis generation. The results were as follows: 1) The experimental group showed significantly higher scores in terms of scientific knowledge generation (i.e. abductive knowledge generation) than the control group. 2) The degree of hypothesis explanation in the experimental group was significantly higher than in the control group in terms of the quality of the generated hypotheses. In addition, students in the experimental group generated more varied and valid knowledge than the control group in terms of sub-knowledge of hypothesis generation. Therefore, it can be argued that this program for hypothesis knowledge generation in elementary science students was effective in the generation of hypothesis knowledge.

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.

The lecture is the main method of teaching, and the most common activity of students is 'listening.' Therefore, efficient and positive changes are expected if the researcher analyzes and uses students' listening styles to educate them. In addition, as the learner-centered education is emphasized, the learner's characteristics are becoming more important, and this flow increases the value of the listening styles of the student and that of the learning strategy, which is the student's self-directed learning. Therefore, this study examined whether there are differences in science achievement according to the listening styles and learning strategies by statistical analysis of the data obtained by conducting surveys for students in 5th, 7th, and 10th grades. The results of this study are as follows: First, students' listening styles and learning strategies show significant differences between men and women. Second, students' listening styles and learning strategies show significant differences between grade levels. Third, the level of task-oriented and critical listening types among listening styles produce meaningful differences in science achievement. Fourth, listening style, learning strategy, and science achievement have a significant correlation with each other. Finally, in terms of learning strategy-science achievement, it was shown that basic and complex cognitive strategy had a positive correlation with science achievement.

This study suggests the direction of management theory education in business administration under the university-linked program of Korean work and study in parallel policy. As a social science, business education is essentially to cultivate people of talent capable of making the right decisions in the social phenomenon (business practices) rather than educate skills for solving a specific issue. At the same time, the parallel system is aimed at cultivating talented people who can work practically in the real field. Therefore, practical education and theoretical education should be linked organically, and the theoretical education should be layered. Also, management education should be guaranteed to be timely and cultivate fusion thinking. Based on this background, this study is expected to contribute to the upgrading of the parallel system and education level in the future by reviewing the curriculum of the business administration department of domestic universities.

This study developed an MEA program to which the invention technique was applied and analyzed the conceptual change of students. The MEA activity applying the invention technique (TRIZ) was composed of the topic of making a paper electric circuit in the section 'Using electricity' presented in the 6th grade textbook. As a way to materialize ideas for problem solving, among the TRIZ techniques, division, integration, multi-purpose, overlapping, subtraction, and converse techniques were extracted and applied. The devised program consists of examining invention techniques (1st session), problem-solving (2nd and 3rd sessions), and expressing the problem-solving process (4th session). As a result of applying to 6th grade elementary school students, it was confirmed that the scientific concept of the experimental group participating in the MEA class to which the invention technique was applied was improved compared to the control group participating in the general class. As a result of calculating the scientific concept improvement index, the control group showed a low educational effect of 0.15, and the experimental group showed an intermediate educational effect of 0.69. This study is meaningful in that it suggests a specific way to graft invention education into science subjects.

For secondary school teachers who attended 'A Social Constructionism Science Teacher Training Program', we analyzed their processes of cognizance change as well as whether they put its results into practice in the field of education, so as to find out the efficacy of the program. 'A Social Constructionism Science Teacher Training Program' consists of three phases based on La main ${\grave{a}}$ la $p{\hat{a}}te$, a French experience-oriented science education program. In its first phase, a study of the philosophy of La main ${\grave{a}}$ la $p{\hat{a}}te$ was made, together with a search for examples of creativity education. In its second and third stages, real education programs were developed for designated themes and free themes, respectively, and then discussions were made. It was a ten-session program, with each session comprising a four-hour sub-program. All activities were both visually and orally recorded, while the participants were asked to write reflective journals for each class. An additional survey and interview were conducted six months later to check if the seven selected secondary school teachers put the results of the program into practice. It was found that changes may be made in the beliefs of teachers with the introduction of theories in teacher indoctrination, but the acquisition of practical knowledge that can be implemented in actual classes may be effectively secured by demonstrations and practice sessions. It was concluded that indoctrination should be conducted to lead participants to the level of practical planning from the level of mere belief so that the theories might actually be put into practice in the education field.
