This study examines the differences and similarities of mathematics teachers' subject matter knowledge among England, the Chinese mainland and Hong Kong. Data were collected from a ten-item test in the SKIMA subject matter audit instrument [Rowland, T.; Martyn, S.; Barber, P. & Heal, C. (2000). Primary teacher trainees' mathematics subject knowledge and classroom performance. In: T. Rowland & C. Morgan (eds.), Research in Mathematics Education, Volume 2 (pp.3-18). ME 2000e.03066] from over 500 participants. Results showed that participants from England performed consistently better, with those from Hong Kong being next and then followed by those from the Chinese mainland. The qualitative data revealed that participants from Hong Kong and the Chinese mainland were fluent in applying routines to solve problems, but had some difficulties in offering explanations or justifications.

The purposes of this study are to find out differences of the causes of mathematics anxiety in elementary school students according to the Grades and sex, and to find out which causes have more influence on achievement of mathematics and how much it is. For this purposes, the problems of this study are defined as follows: First, are there any differences in the influences of each super-causes and sub-causes of mathematics anxiety according to the Grades? Second, are there any differences in the influences of each super-causes and sub-causes of mathematics anxiety according to the sex? Third, what relation do the super-causes of mathematics anxiety have to the achievement of mathematics? The conclusions of this study are as follows: First, mathematics anxiety is much more affected by the internal cause like the cause of student attitude than the external cause like the causes of circumstance and the cause of teacher. Second. mathematics anxiety is much more affected by a direct experience like the causes of a shortage of time and the causes of student interest than indirect experience like the causes of teacher's authority and the causes of the application of daily life. Third, the causes of circumstance and parent's attitude. its sub-cause, have greater influence on the female group than on the male group. Fourth, in the middle Gradess, the female group is more affected by the cause of student attitude and the cause of circumstance than the male group, but in the higher Grades. the differences disappear and those two become common causes of anxiety. Fifth, As the students go up to the next Grades in school, the cause of teacher, the characteristic of the curriculum and the cause of prejudice have more influence on the mathematics anxiety. Sixth, the causes of teacher, the causes of mathematical curriculum and the causes of student attitude among super-causes of mathematics anxiety have a negative effect on the achievement of mathematics. But the causes of circumstance have a positive effect on it. And also, the causes of mathematical curriculum among super-causes is much related to the causes of teacher and the causes of circumstance.

The purpose of this study is to explore the effect of responsive teaching on students' productive argumentation practice. The participating students predicted the results of an activity to measure in which location on the body (the head, spine, or back of the hand) they would feel a cellphone's vibrations faster. They then engaged in the activity and built an argument to justify it. We interviewed the teacher to understand her thoughts regarding what was expected in the class. We also recorded and transcribed the class and the interview, for use in the analysis of the students' epistemological framing and the teacher's responsive practice in small group argumentation. We discovered that the teacher intervened in the groups with questions that elicited students' thoughts as starting points for her responsive practice. Her eliciting questions led the students to talk about their ideas, supporting their engagement in the argumentation. The teacher's understanding of the argumentation lesson and her behavior to understand the students' ideas reflected her productive framing, which led her to elicit students' ideas and to support their active interaction during the small-group argumentation. She presented rebuttals against students' ideas, engaging in the argumentation as another participant, not as an evaluator. This supported the equality of intellectual authority in the group and showed students how to engage in the argumentation, supporting students' productive framing. As a result of these responsive teaching practices, the students shifted their epistemological framing, resulting in productive argumentation practice. The results of this study will contribute to developing teachers' responsive teaching strategies to support students' productive framing in science classrooms.

Followed by government authorized data that Ministry of Education submitted, safety accident at school has been increased year by year. Safety accident occurred 33,834 in 2005, 29,955 in 2004, and 22,722 in 2003. It shows that it has been increased about 12.9% from 2004 and 48.9% in 2003. Level of student's development, students are at the point of not having enough judgement and ability to adapt at emergency situation. They are learned about safety by education and management by teachers but teachers will get heavy burden and anxiety if government doesn't provide more improved support and restraint. On this situation, educational authority can be attacked and it legally charged by nation, owned property can be loss or prosecution can be occurred. Also school safety accident which occurs in these days is working as an negative insecurity element that teachers cannot concentrate on the education.

This study examined what meaning East Asian women showed in their costume history through a discourse of hair adornments such as wigs and that Gache was not just a luxury decoration. In addition, we examined Gache hair trends with Eonjeun-meori (braid wraps around the entire head) in the Joseon dynasty (Korea), Gigye(旗?) hair in the Quing dynasty (China) and Mage(?) hair in the Edo period (Japan) during the $18^{th}$ and $19^{th}$ centuries. The significance of the phenomenon of East Asian Gache culture in the $18^{th}$ and $19^{th}$ centuries was analyzed from the internal desires of women. The details are as follows. First, the magnification by the hair decoration was identified with self-authority and used as a sign to express self-respect or a desire for self-esteem. The extended Gache was an external body extension to raise self-authority and increase activeness. Second, self-satisfaction through showing off was associated with a women's search for identity. There was excessive consumption to boast status, wealth and femininity, but the mania continued because women obtained psychological satisfaction by feeling that their sacrifices for the Confucian order were compensated. Third, the frenzy of Gache was accepted as a way for women to resist social regulations and find themselves as main participants in social activities. Showing their appearance in East Asian Gache culture was a way of inner self-searching and a process for women to find themselves as a social entity.

This study focused on research that illustrates the important interplay between learners' epistemological beliefs about science knowledge, physics textbook knowledge and knowing physics in the classroom. Also this study investigated learners' conceptual changes on the value of mechanical energy. To explore these topics, six sophomores were chosen as participants. Three categories were introduced to classify how participants' understanding of the nature of science knowledge, physics textbook knowledge has been linked with epistemological beliefs of knowing physics. The three categories were (1)receiving physics knowledge as authority, (2)receiving physics knowledge as the perception of teacher's role and (3)understanding physics knowledge as the perception that science knowledge is a product of a variety of human ideas. These categories were also concerned with construction of individual conceptions of mechanical energy. The participants who understood physics knowledge as the perception that science knowledge is a product of a variety of human ideas naturally used metacognitive strategy in classroom compared to other participants. And they had scientific conceptions about the value of mechanical energy. Others who were passive in classroom had unscientific conceptions about the value of mechanical energy due to definition of energy and epistemological beliefs about the nature of science knowledge. In the process of their conceptual changes on the value of mechanical energy, it was important to understand an instrumental aspect of scientific knowledge and to think about the relation between formulae and physical phenomena.

The purpose of this study is to examine the influence of the distributed leadership upon kindergarten teachers' commitment of teachers. As a result of the analysis, first, the teachers' recognition on the distributed leadership at a kindergarten was confirmed to have a significant difference depending on the teaching career and the academic background. And the commitment of teachers perceived by the kindergarten teachers was identified to have a statistically significant difference according to the teaching career, academic background, and scale. Second, the kindergarten situation and the teacher leadership among sub-factors of the distributed leadership were indicated to have a positive effect on the commitment of teachers. Especially, the teacher leadership was confirmed to have a positive impact on the whole of professional consciousness, educational love, and passion, which are sub-factors in the commitment of teachers. What the distributed leadership has a positive influence upon the commitment of teachers at a kindergarten can be known to be ultimately the time when a teacher oneself fully recognizes responsibility, influence, and authority with thinking that a teacher oneself is a leader, rather than a director's leadership. Accordingly, a director's many responsibilities and authorities need to be properly entrusted so that the kindergarten teachers can display much more leadership.

Knowledge is composed through the interaction between the concept structure already held by students and their experience, and learning can be said to be the active process of solving the cognitive conflict caused by this interaction. Therefore, this study consists in showing the effective learning method and finding out the elements which the teacher has to own, through examining several forms of pre-conception or mis-conception of the inertia, the force-equilibrium, the action and reaction, the heat, and the electric current, and then finding out their solution and studying student's change in science concepts. For this study, the types of concept on the five above-mentioned materials which students have were examined through the concept-classifying question paper, and the classes to which the class mode for the change of concepts applied, were practised in each different classroom by each different instructor - a professor, a scientist, a teacher, and two students, respectively. And the effect of the teaching strategy based on these classes, and each different instructor' influence on the change of concept in students. were examined. The result of my study is as follows; 1. Students have various types of pre-conception which are different from science concept, and these types of pre-conception tend to last even after learning in class. 2. The thoughts on the correct science concept of the high school third-grade students who learned the physics in the traditional teaching method, and the second grade students who don't learn the physics yet, were nearly equal those of the second grade students by receiving the physics class through the cognitive conflict course were greatly changed especially that students showed the distinct change on mechanics and electric current. 3. Students didn't show the remarkable change of the science concept on the five materials in the four kinds of experimental classes by each different instructor but in the part of mechanics, there was the distinct change between the class by professor and those by the students. This was due to the difference of the authority and the attitude of the concept demonstrator. 1) The authority, the kind attitude, and the responsibility of the expert played an important role in the correct concept-formation of mechanics part - especially in the case of the mis-conception caused by the intuitive belief. 2) In the class by instructor with the democratic teaching method, the change of concept took place more easily, because in his class students could discuss the subject freely, so that they might experience the thought course to give them the confidence on the science concept.

The purpose of this research is to investigate the characteristics of beginning science teachers' subject matter knowledge (SMK) as revealed in their classroom teaching methods. In this research, we explored six beginning teachers' classroom teaching episodes on the 'work and energy' unit. Using open-ended interviews with the teachers and group discussions taking place on a regular basis to analyze and compare the classes of six beginning teachers, we extracted the features of beginning science teachers' SMK. Using grounded theory methods, the characteristics of beginning science teachers' SMK drawn from this research are: (1) beginning teachers' positivistic epistemology on science, (2) claiming the teacher's authority based on rich subject content knowledge, and (3) beginning teachers' science elitism. These epistemological characteristics are realized such PCK as (1) representational errors caused by the teacher's own science misconception, (2) doing harm to students with too much content knowledge, (3) sporadic content presentation lacking a focus, and (4) surplus class hours with lack of effective science teaching explanations. Suggestions for alternative perspectives on science SMK are presented by experienced teachers. In conclusion, science teachers' SMK is necessary, but not sufficient, for effective teaching. Science teachers' SMK does have an effect on science teaching, mediated by other types of teacher knowledge. The beginning teachers need a systematic support to transform their SMK into a viable PCK.

Purpose: This study aims to examine how elementary, middle and high school health teachers in Gyeonggi province react to infectious disease like MERS. Methods: This is a descriptive study using a convenience sample of 1,267 school health teachers. Results: When MERS was an epidemic, school health teachers who took the 'leading' role were 92.4%. A school heath teacher's countermeasures against infectious diseases showed a high score during MERS outbreak (3.81) compared to regular days (3.59). Conclusion: Based on such results, it has been determined that schools need to keep two types of procedures manual, such as 'countermeasures on a regular basis' and 'countermeasures in the event of a pandemic disease outbreak' manual in the staff offices so that anyone can view them at any time. It is necessary to prepare regulations to strengthen their authority so that school health teachers can take the role of control tower, in a professional capacity, when communicable disease is spreading. In order to prevent any confusion and chaos, there should be a unitary reporting system at each school when dealing with an epidemic. School health teachers need to get continuous training to reinforce their abilities to react to communicable diseases.
