This study aims to investigate the disparity between the teacher's perception of student-centered inquiry classes and the actual implementation of such practices. Specifically, we compared an elementary science teacher's self-perception of her science lessons with the observers' evaluation using the Reformed Teaching Observation Protocol (RTOP) of the "Temperature and Heat" unit. Research data were collected through classroom teaching survey, interview, and science lessons video which were analyzed using the RTOP. As a result of the study, the teacher recognized that she was practicing inquiry-oriented/student-centered classes, but the results judged by the RTOP score were found to be transitional/student-affected classes by a slight difference. Teacher H planned and practiced classes based on a high understanding and content knowledge of the curriculum and created a science classroom culture that promotes active interaction among students as well as students and teachers. However, teacher-led aspects were still emphasized in teaching design and implementation, and the project theme and content were inappropriate to improve the quality of students' science inquiry experience. In the end, the slight difference between teacher's perception of inquiry-oriented/student-centered classes and actual implementation is related to how student-centered "lesson design" is and how to plan and implement classes supported by "procedural knowledge" for students' experience in the science inquiry process. These results indicate that the teacher's self-evaluation alone is not enough to determine whether the teacher's intentions and efforts are actually being implemented, and that it is necessary to conduct objective analysis, evaluation, and discuss the results of science classes by the external observers.

In this study, we examined classroom interaction to explore the relationships among teacher questions, turn-taking patterns, and student talks in mathematics classrooms. We analyzed lessons given by three elementary teachers (two first-grade teachers and one second-grade teacher) who worked in the same school using a conversation-analytic approach. We observed individual classrooms three times in a year. The results revealed that when teachers provided open-ended questions, such as "why and how" questions and "agree and disagree" questions, and used a non-IRE pattern (teacher initiation-student response-teacher feedback; Mehan, 1979), students more actively engaged in classroom discourse by justifying their ideas and refuting others' thinking. Conversely, when teachers provided closed-ended questions, such as "what" questions, and used an IRE pattern, students tended to give short answers focusing on only one point. The findings suggested teachers should use open-ended questions and non-IRE turn-taking patterns to create an effective math-talk learning community. In addition, school administrators and mathematics educators should support teachers to acquire practical knowledge regarding this approach.

The purpose of this study is to analyze the characteristics of beginning teachers in elementary school as they experience the lifecycle of teachers, to analyze and comprehend the difficulties of these teachers based on their characteristics, and to propose a resolution strategy. The study is intended to assist beginning teachers in adapting well to their work and profession as teachers in order to contribute to the growth in quality of education; it is also intended to prepare beginning teachers to utilize their time in elementary school as a period of self-improvement to become proficient teachers. The difficulties in human relations that beginning teachers experience in school can be divided into three major categories: relations with administrators and fellow teachers, relations with parents of students, and relations with students. The standardized and uniform culture of a school and the administrators and fellow workers imposing such a culture are the reason for the difficulties that beginning teachers face, and the question of what kind of fellow teachers the beginning teachers will encounter in their first school exerts a serious influence on the growth of these teachers, who have just begun their career in education. Furthermore, the lack of skills to discipline students eventually leads beginning teachers to face difficulties in controlling students in the classroom, and the process of encountering and resolving various classroom problems contributes to the growth of teachers' proficiency. Moreover, the attitude of students' parents who behave toward them as novice teachers serves as the reason for beginning teachers to lose their confidence or face difficulties in their careers, and exerts an influence on student counseling and guidance. The resolution strategy that beginning teachers apply as they encounter such problems with the entities in the educational field is as follows: imitation, listening, and accepting the thoughts and to renounce. To resolve the difficulties that beginning teachers experience, it is necessary to allocate space and time to discuss their difficulties and possible plans for resolution during the beginning teachers' training period and initiate a mentoring system in schools. Lastly, it is necessary that the offices of education continuously conduct qualitative research on beginning teachers and publish casebooks on such studies.

This study analyzed student noticing in a lesson that emphasized relational understanding of equal signs for first graders from four aspects: centers of focus, focusing interactions, mathematical tasks, and nature of the mathematical activity. Specifically, the instructional factors that emphasize the relational understanding of equal signs derived from previous research were applied to a first-grade addition and subtraction unit, and then lessons emphasizing the relational understanding of equal signs were conducted. Students' noticing in this lesson was comprehensively analyzed using the focusing framework proposed in the previous study. The results showed that in real classroom contexts centers of focus is affected by the structure of the equation and the form of the task, teacher-student interactions, and normed practices. In particular, we found specific teacher-student interactions, such as emphasizing the meaning of the equals sign or using examples, that helped students recognize the equals sign relationally. We also found that students' noticing of the equation affects reasoning about equation, such as being able to reason about the equation relationally if they focuse on two quantities of the same size or the relationship between both sides. These findings have implications for teaching methods of equal sign.

This research is how students and teacher apprehend mathematics education, pointing out problem areas as a basis on how to improve students understanding of mathematics through improved guidance by teachers in the future. 1107 high school students and 105 teachers from around Daejeon and Choongnam province were surveyed and the results were as follows. 1. 77 %( 852) of students viewed the "application of problem solving methods" as understanding mathematic problems. 2. Replies to the question on understanding the study of mathematics resulted in 85.7% of teachers saying "it is the understanding of the basic concept to which you solve the problems" 3. For questions relating to the large difference in-class mathematics achievements and mock University entrance exam achievements, students' response that "for in-class tests you only have to learn problems with similar form but the mock tests are not like that" pointed out the problem in the area of mathematics education. 4. For future mathematic education teachers will have to "explain better and more completely the basic principles and concepts before solving problems" , and make an effort to stimulate students by "creating a more fun atmosphere" . There will also be the need to prevent as much as possible, the use of "formula or memory driven problems" and encourage students to initiate problem solving for themselves.; and encourage students to initiate problem solving for themselves.

This study examined the relationship between homeroom teachers' transformational leadership, high school students' satisfaction in school life, and learning motivation. The researchers selected boys and girls' general high school as the target population and gathered survey data. The number of participants was 606; these were students from first and second grades. Questionnaires on teachers' transformational leadership, students' learning motivation, and satisfaction in school life were measured. T-tests showed the following: As a result of the analysis of the difference of transformational leadership, the average of the teachers with careers spanning over 15 years was statistically significantly higher than those whose career spanned over less than 5 years. The group which perceived the transformational leadership of the homeroom teacher as high showed higher motivation scores than the group with lower perception. The means were statistically significant in all the sub-variables. In school - life satisfaction, the average of the former group which perceived the transformative leadership of the homeroom teacher as high was significantly higher than that of the other group.

In this study, we analyzed the characteristics of Pedagogical Content knowledge(PCK)'s components through actual course of teachers of science gifted students in the middle school. For this study, four middle school science teachers of gifted students belonging to the gifted education professional organizations in a metropolis were selected, each of them was physics, chemistry, biology, and earth science teacher. Two of them were full-time teachers to teach only gifted students and two were part-time teachers who had taught general students in ordinary time and specially had taught the gifted students once a week. Qualitative data were collected through classroom observations, interviews, and documents. As a result, some unique characteristics of PCK's components were identified. The teachers' orientations to teaching science were closely correlated with PCK's components. The teachers' knowledges of science curriculum were different individually. But the decisions about type of teaching(acceleration or enrichment) were connected with the objectives of gifted education and lesson objectives. Also, the teachers' knowledges of science curriculum were influenced by the knowledge of students' understanding. Teachers used different instructional strategies according to the knowledge of science curriculum and the knowledge of students' understanding. We found that PCK's components were so closely connected and could show the direction of relationships among those PCK's components. We suggested teachers' PCK model which was named "Tetrahedron Model of PCK", to explain the characteristics and relationships of PCK's components.
