This study has been established with two purposes. The first one is to development the learning-teaching model for enhancing students' creative proof capacities in the domain of demonstrative geometry as subject content. The second one is to aim at experimentally testing its effectiveness. First, we develop the learning-teaching model for enhancing students' proof capacities. This model is named the generative-convergent model based instruction. It consists of the following components: warming-up activities, generative activities, convergent activities, reflective discussion, other high quality resources etc. Second, to investigate the effects of the generative-convergent model based instruction, 160 8th-grade students are selected and are assigned to experimental and control groups. We focused that the generative-convergent model based instruction would be more effective than the traditional teaching method for improving middle school students' proof-writing capacities and error remediation. In conclusion, the generative-convergent model based instruction would be useful for improving middle grade students' proof-writing capacities. We suggest the following: first, it is required to refine the generative-convergent model for enhancing proof-problem solving capacities; second, it is also required to develop teaching materials in the generative-convergent model based instruction.

This research was conducted to develop an assessment measure of attitude toward engineering. Based upon related document research and case studies, we came up with operational definition and category of attitude toward engineering as well as questionnaires to assess. After consulting with specialists and studying on relevant documents, we changed some of the 60 questions developed in the first phase or added new ones. One hundred and nine students who major in engineering were questioned by the 40 questions selected in the second phase. Using SPSS 14.0K statistics program, various techniques were used including factor analysis, validity analysis and correlation analysis. And the level of significance of statistical verification was 0.05. The result is as follows: Based on fundamental aspect of the attitude, this research focused on 3 different variables: cognitive variable such as 'attitude toward engineering value', affective available such as 'general attitude toward engineering and attitude toward engineering study', Behavior available such as 'participation in engineering activity'. Therefore, as a subcategory, attitude toward engineering value is classified into value as study and job, social value and personal value, general attitude toward engineering and attitude toward engineering study are divided into self-concept, self-efficacy, awareness, interest and cooperation. Also, participation in engineering activity is classified into attitude toward engineering study. After applying this measurement to the field, we integrated self-concept into self-efficacy, omitting one independent factor in the question. Finally, through Verimax, we developed 'Instrument of Assessment the Attitude toward Engineering(IAAE)' which consists of 3 variables, 9 subcategories and 39 questions.

Recently, there has been a dramatic increase in the number of cases that have formed and operated teachers' learning communities through cross-curricular consulting at the school level. The purpose of this study is to explore cross-curricular instructional consulting as an activity of teachers' learning communities at the school level, and investigate the effect of cross-curricular instructional consulting on middle school science teaching. We analyzed features and limitations of cross-curricular instructional consulting revealed in three case studies in middle school, including open classes and instructional consulting sessions, and conducted additional instructional consulting on the same videotaped science classes with science experts from outside. According to the results, science inquiry experiments are often replaced with text reading and interpreting, students' misconceptions and exact scientific representations are ignored, and the goal setting as well as class coverage has been questionable and disputable in science classes resulted from cross-curricular instructional consulting. Discussed in the conclusion are the necessity of cross-curricular instructional consulting in middle school, and ways to overcome limitations of the method of cross-curricular instructional consulting, including alternatives to a praise-only policy in cross-curricular instructional consulting, ways to use cross-curricular instructional consulting without compromising the subject's essence, and ways to improve the undue authority of consultants.

This study was to explore epistemological features presented in texts of exhibit panels in the science museum located in Gyeonggi Province. Out-of-school or daily experiences allow more properly and potentially students to form informative science image, because the understandings of scientific epistemology were constructed tacitly through various experiences over a long period of time. The target for this study was panel texts of exhibits in a science museum as an of out-of-school context. The analytical framework was adopted from epistemological frameworks by Ryder et al. (1999). The research results were explored in the categories of relationship between scientific knowledge claims and the data, the nature of lines of scientific enquiry, and social dimension of science. It revealed that one exhibit might reflect the characteristics of one epistemological position: relating one data to one knowledge claim; generating knowledge claim from scientists' individual interests or from discipline's internal epistemology; scientists working as a community or an institution. Findings suggested that the exhibits of a science museum including panel texts and medium need to reflect the wide ranges of scientific epistemology.

The purpose of this study is to investigate the challenges of pre-service teachers for good science teaching with focus on the process of imparting meaning of teaching subject. We have detailed research questions such as, 'What the pre-service teachers thought about teaching subject? How they grasped the meaning of the teaching subject? and What kinds of methods they have used to expose the meaning in their classes?'. We had four pre-service teachers who took the class 'Teaching methods in physics teaching' as voluntary participants in the first semester of 2017. The results show that there are common features in the process of imparting meaning of the teaching subject. The participants started to think about fundamental/existential answer to the question, 'Why should we teach science to students?'. In addition, they grasped the meaning of the teaching subject by using the specific key words. And they tried to link the teaching components with the teaching subject as the center. This challenging process led pre-service teachers to form teachers' identity and to enhance teacher professionalism.

In this study, we propose research methods to explore the nature of earth science by applying the phenomenological approach and NOS-family resemblance approach based on literature review. The phenomenological approach exploring the nature of earth science is a method of collecting, analyzing and synthesizing multifaceted features of earth science from intuitive sensory phenomena without prejudice. As a way of exploring the nature of earth science from a phenomenological point of view, we propose the NOS-family resemblance approach to the NOS. This approach provides a comprehensive explanation of NOS by combining the characteristics shared by different areas of science with distinct differences. Applying this method to exploring the nature of earth science, we can identify both domain-general and domain-specific characteristics that make sub-areas of earth science a 'family.' For example, through the networking of features shared by such sub-areas as geology, atmospheric science, oceanography, astronomy, earth system science, etc., we can extract the family-resemblance characteristics that make these sub-areas a family called earth science. Through these approaches to the nature of earth science, the richness, complexity, and dynamic nature of earth science can be revealed as a whole. In addition, we will be able to grasp the change in the sub-areas that constitute the earth science, which in turn changes the nature of earth science, and to contribute to establishing the status and development system of earth science as a school subject.

In the current classrooms a teacher has been merely able to inculcate the procedural knowledge of how-and-what. In doing so, however, we lose sight of the essence of "doing science."Though desire of the gifted children is qualitatively different from that of normal children, it is an undesirable reality that we have not developed sufficient researches and programs in conformity with the necessary desire and demand of the gifted children. Curriculum for gifted children in the domain of science necessitates markedly the specializations for the specific areas of the contents, the processes, and the products of studies. In an effort to provide the optimum learning experience for the gifted, this paper deals with the development of project-and-discovery-based science program, its method of application to the real field of education, and its effect, however limited and partial that effect may be. What this study has found are the following: on the one hand, the students acquired and developed the higher levels of thinking when they were under the influence of project-and-discovery-based science program that dealt with concrete real-world problems and issues; on the other, the students were capable of solving creatively the complex and real problems through small group activities. This study also suggests the possible implications of project-and-discovery-based science program: the students can not only learn the contents of study but also apply them creatively; the students can cultivate critical thinking skills that can be a fundamental base for a life-time leaner; the students can naturally acquire the abilities of communication and coordination. Project-and-discovery-based program is currently used in the various disciplines. However, the field of gifted education does not yet implement this type of program. So the overall contribution of this study is to show the successful implementation of project-and-discovery-based science program in developing optimal teaming experience for gifted children in the domain of science, since this type of study is most compatible with the characteristic of the gifted children. children.

Controversy and legal disputes over counterfeit fashion designs have recently arisen in the fashion industry. The purpose of this study is to examine cases of counterfeiting disputes over fashion designs, and how the perception of counterfeit fashion designs is fostered from the learner's point of view, suggesting implications for the counterfeiting problem. As a result of this study, first, counterfeiting disputes over fashion design started from a lack of utilization of the Design Protection Act and the ambiguity in counterfeit design criteria. Second, the negative perceptions of counterfeit designs were mainly about unethical behavior, inhibiting the growth of the fashion industry, and reducing consumers' willingness to buy the genuine article. Positive perceptions were mainly about the process of creation, the promotion of a developmental environment for the fashion industry, and the expansion of opportunities to promote new designs. The most common perception was the absence of clear criteria for judgments about counterfeiting. Third, the implications of the counterfeiting problem in fashion design require effective institutional improvement in the fashion industry, the establishment of standards to deal with counterfeiting, the development and practical introduction of education proposals regarding intellectual property rights, and changing the perception of counterfeiting in the fashion industry.

The Purpose of this study was an analysis of high school student's understanding level about concepts of special relativity through in-depth interview. The 8 participants were 10th grade students in H high school in Ulsan city, who were interviewed and analyzed in the results of the interview about basic concepts of special relativity using achievement checklist in 6 situations(principle of constancy of light velocity, principle of relativity, relativity of simultaneity, garage paradox, rocket paradox). As results of the checklist, the participants showed high achievement in the content level of simple phenomena and simple concepts related to special relativity. But they showed low achievement in the concept level for fundamental understanding of special relativity. As results of the interview, it was found that the participants decided the order of events depending on their intuition and had a difficulty to apply the coordinate system to real situation, even though they mathematically understood it. In addition, some participants who could not understand the inertial coordinate system explained paradoxes of relativity depending on their intuition and had learner's chaos. Finally, though high school students usually being in formal operational stage, some students had difficulty to draw phenomena of space and time in two dimensional plane.
