In this study, to disseminate the Practical On-site Cooperation Model (POCoM) for practical improvement of science teaching and learning through cooperation between researcher and teacher, an in-service program has been developed, applied and evaluated. The in-service program emphasizes the following three aspects; (1) video-recording of actual science teaching has been used as a primary resource, (2) communication between teacher and researcher and among teachers have been emphasized, (3) activities have been mainly included. The in-service program has been implemented for nine hours, and 17 science teachers have been recruited as volunteers. The result shows that, by checking the agreements between raters, we found that teachers' expertise in analyzing the science class using the Korean Teaching Observation Protocol (KTOP) has improved, and we have confirmed that teachers are able to judge whether the science class has improved or not. Through the questionnaire, various highly positive responses could be obtained from teachers. And through the observation of teachers' activities during the in-service program, teachers' questions, their difficulties in doing activities, and their comments for improving the program has also been analyzed. Finally, based on the results, a list of recommendations for a more effective in-service program have been suggested. It is expected that this list can be utilized for more effective and meaningful design and implementation of in-service course.

The purpose of this research was to examine the problems, confidence and satisfaction of teachers on the subject ${\ulcorner}technology and home economics{\lrcorner}$ in the 7th national curriculm. For this research, questionnaires were sent by post to teachers who teach technology and home economics in middle schools and high schools. The collected questionnaires were technically analyzed by SPSS/WIN 10.0 program, which measured frequency, percentage, average, standard deviation. According to the types of data, they were also analyzed by t-test and cross tabulation analyses. The results of this research were summarized as follows. 1) There were two teaching types of technology and home economics: the partial charge and the whole charge teaching according to teachers' majors, and both types occurred in similar percentage. The partial charge teaching means that teachers majoring in technology teach only the technology part and teachers majoring in home economics teach only the home economics part when they teach the same subject, technology and home economics. These days the partial charge teaching more often occurs in national or public schools than in private schools, and in coeducational schools than in girls' or boys' schools. 2) The major problems of teaching technology and home economics were caused in order by teachers' lack of skills and knowledge which we not their own major, the lack of students' interests and teaching materials, and burden of tests. 3) Teachers' confidence in teaching the contents of the subject, technology and home economics, made a significant difference according to their majors. Teachers whose major was technology felt more confident when they taught the chapters of the textbooks related to their major, technology, while teachers whose major was home economics felt more confident when they taught the chapters of the textbooks related to their major, home economics. According to implementation types, the partial charge teaching gave higher confidence to the teachers than the whole charge one in teaching almost all the chapters of the textbook. 4) According to implementation types, teachers' satisfaction was showed to be higher in the partial charge teaching than in the whole charge one.

The purpose of this study was to examine the relationship among child care teachers' role performance and burnout, and supervisors' support. The subjects in this study were 171 child care teachers working in Gyeonggi province. Role performance questionnaire, the perceived supervisor's support scale, and the perceived burnout scale were used for this study. For the research analysis, frequency, Cronbach's ${\alpha}$ coefficient, and Pearson's correlation were calculated and regression analysis were conducted. The results are as follows. Firstly, it was revealed that both child care teachers' role performance and the perceived supervisors' support had statistically negative significant correlations with child care teachers' burnout. Secondly, role performance had statistically meaningful negative influences on child care teachers' overall burnout. Training and teaching activities as a sub-variable of child care teachers' role performance had statistically meaningful negative influences on emotional exhaustion, a lack of feeling of personal accomplishment, and overall job burnout. Thirdly, supervisors' support also had statistically meaningful negative influences on burnout. Material support as the sub-variable had statistically meaningful negative influences on emotional exhaustion, dehumanization, a lack of feeling of personal accomplishment, and overall job burnout. Evaluative support had statistically meaningful and negative influences on dehumanization and a lack of feeling of personal accomplishment. Through the results of this study, it must be indicated that it needs to promote the support of the supervisor in the various aspects and to provide a way which child care teachers efficiently perform the role in order to reduce their burnout.

The purpose of this study is to investigate the development of scientific conceptual understanding through a process-centered assessment that visualizes the process of scientific argumentation. In this study, 353 high school students and five teachers participated in the scientific argumentation. As a result of analyzing students' utterances on the elements of argumentation, scientific concepts in intragroup were embodied through query and clarification of meaning, and organized through agreement and rebuttal. In intergroup argumentation, scientific concepts were elaborated through query, clarification of meaning, and change of claim. Teachers were able to understand the process of argumentation through small-group activity sheets where the process was visualized, thereby providing feedback and improving the class. Based on the results, the scientific argumentation of visualizing the process was found not only to allow students to perform self-assessment and peer-assessment but also to help teachers understand the argumentation process. The findings of this study guide process-centered assessment in the science curriculum and are expected to contribute to the promotion of scientific argumentation in classrooms.

This study recruited 11 teachers with experience in guiding science exhibitions nationwide to investigate the perception and necessity of teachers as educational consumers of science exhibitions, one of the out-of-school science education activities, and conducted an in-depth written survey. An average of more than 3,600 characters answered a total of seven questions in writing, and through qualitative analysis, the growth of students and teachers due to participation in science exhibitions, difficulties in participating in competitions, and teachers' voices for revitalization were recognized. Teachers offered positive opinions in that participation in science exhibitions improves students' knowledge and attitudes related to science and experiences an open inquiry process linked to career advancement in science and engineering. However, the students who participated in the competition failed to record the contents of the inquiry in their school records, and instructors pointed out the obsession with discovering novel topics, the burden of guiding the inquiry process, and the limitations of their expertise in major knowledge. In order to revitalize science exhibitions, 17 city and provincial education offices called for measures to strengthen the capabilities of instructors and students, improve the promotion and screening methods of the National Science Museum, and improve the Ministry of Education's school records.

This study intends to investigate the features and the difference between traditional instruction and flipped learning through a comparative analysis of verbal interaction on those learning method. The videos of traditional instruction and flipped learning of 5th graders social class were recorded and transcribed, which were analyzed in Flanders verbal interaction model. The results were as follows: First, the flipped learning is composed of students' learning activity and a teacher's statement properly, while the traditional instruction consists of a teacher's statement mostly. Second, the traditional instruction tends to be directive classes that full of dominant, despotic, restrictive communication of teacher oriented. In contrast, the flipped learning is inclined to be nondirective with integrated, democratic, comprehensive, permissive communication of students oriented. Third, the flipped learning emphasizes students' activities and statement and reduces delivery of knowledge, meanwhile, the traditional instruction stresses delivery of content that the teacher centrally located. Lastly, the type of verbal interaction in traditional instruction is a one-way communication, students responding simply in teacher's lectures and questions. On the other hand, in flipped learning lessons, more interactive communication occurs, teachers complimenting students and accepting their comments.

Robot programming allows students to plan an algorithm in order to solve a task, implement the algorithm, easily confirm the results of the implementation with a robot, and correct errors. Thus, robot programming is a problem solving process based on reflective thinking, and is closely related to students' metacognition. On this point, this research is conducted to develop a robot programming instructional model for tile enhancement of students' metacognition. The instructional processes of robot programming are divided into 5 stages (i.e., 'exploration of learning tasks', 'a teacher's modeling', 'preparation of a plan for task performance along with the visualization of the plan', 'task performance', and 'self-evaluation and self-reinforcement'), and core strategies of metacognition (i.e., planning, monitering, regulating, and evaluating) are suggested for students' activities in each stage. Also, in order to support students' programming activities and the use of metacognition, instructional strategies based on cognitive apprenticeship (i.e. modeling, coaching and scaffolding) are suggested in relation to the instructional model. In addition, in order to support students' metacognitive activities. the model is designed to use self-questioning, and questions that students can use at each stage of the model are presented.

The purpose of this study is to qualitatively examine the effects of graphics representation of trigonometry modelling concerning question generating and idea sharing. The experimental setting(Experiment Group) was one class (N=26) at a public high school. The modelling process was designed as a process-oriented conceptualization divided into three steps i.e., (1) game with idea sharing and question generating, (2) graphic representation, and (3) symbolization in the mathematical applied tasks related to trigonometry function. The result indicates that Graphic Representation with Game Activity increases the opportunity of question generating and idea sharing during experimental work. Also, the results show that the introduction of computer graphics enhances the teaching of mathematical quantity in highschool classrooms.

Science inquiry has long been emphasized in Korean science education. Scientific modeling is one of key practices in science inquiry with a potential to provide students with opportunities to develop their own explanations and knowledge thereafter. The purpose of this study is to investigate teacher's understanding of models in science and science teaching. A professional development program on Models (PDM) was developed and refined through three times of implementation while teachers' conceptions of models and modeling were examined. A total of 29 elementary and secondary teachers participated in this study. A survey based on model use of scientists in the history of science was developed and used to collect data and audio recordings of discussions among teachers and artifacts produced by the teachers during PDM were also collected. Three ways of ontological and two ways of epistemological understanding of models and modeling were found in teachers' ideas. After PDM, a quarter of the teachers changed their ontological understanding whereas very few changed their epistemological understanding. In contrast, more than two thirds of the teachers deepened and extended their ideas about using models and modeling in teaching. There were no clear relationships between teachers' understanding of models and ways and ideas about using models in science teaching. However, teachers' perceptions of school conditions were found to mediate their intention to use models in science teaching. The findings indicate possible approaches to professional development program content design and further research.
