The purpose of this study was to investigate role perception, knowledge, self-confidence of practice, and educational needs of child daycare teachers' infectious disease management and to identify their relationship. A correlation study was conducted. Participants were 180 child daycare teachers. Almost eighty percent(78.9%) of participants did not received infectious disease management education. The mean percent of correct answers for infectious disease management knowledge of participants was 52.3% and their self-confidence of practice of infectious disease management was low. However, their role perception of infectious disease management and educational needs were high. Educational needs on 'hand washing and hygiene to prevent infectious diseases', 'blocking transmission of infectious diseases', 'infectious disease specific management and care', and 'infectious disease specific symptoms' were high. Child daycare teachers' role perception of infectious disease was positively correlated with their knowledge and educational needs. Development and evaluation of educational interventions to improve child daycare teachers' infectious disease prevention and management are recommended. Particularly, efforts are needed to improve child daycare teachers role perceptions as infectious disease manager.

This research aims at investigating science teachers' perception of the refractive index of materials, and thus achieving proper information transmission and teaching of refractive index. Specifically, we have made questionnaires on what physical factors influence the refractive index of a liquid easily available in secondary schools. It was found that 80.0% of science teachers perceived that the density has the greatest influence on the refractive index, among a variety of factors such as molecular structure, the number of molecules per unit volume, mass of each molecule, and the wavelength of light, to mention just a few. This may be due to the fact that current textbooks deal with the refraction of light based on analogy to a mechanical wave. Such a misunderstanding may lead to confusion and misunderstanding for students.

We examined how science teachers in middle schools practiced and perceived using analogies. A survey was administered to obtain 131 teachers' responses from 22 middle schools in Seoul. Most science teachers used analogies frequently in their instructions, and had positive attitudes toward the effect of analogies. They agreed that relevant figures should be presented with analogies, analogy itself should be explained to their students, and something to mislead the students' idea should be mentioned. They also responded that they practiced so in their instructions. However, it was revealed that they neither explained a concept with several analogies nor helped students to make self-generated analogies. Their idea was that proper analogy sources and instructional models were needed for using analogy effectively in science instruction. The teachers with above masters degree explained the analogy itself, and they perceived the needs for supplements and strategies in using analogy more affirmatively. The teachers possessing modern perceptions to science instructions and students' activities rather than classical ones used analogies more frequently and effectively.

The purpose of this study is to assess pre-service elementary teacher's conceptions of environmental issues. 141 pre-service elementary teachers from local college participated in this study. We discovered that most of participants understood the possibility of technological abuse that could lead to environmental destruction. They also well understood the crisis of the Earth's ecosystem. Nevertheless, it seemed most of participants were not ready to take action to save ti. In addition, they also showed stereo-typically biased opinions about science, technology and their relationship with environmental issues. It appeared to come from media-oriented environmental education. Since pre-service teacher's conceptions could directly effect future education, it is necessary to establish a more systematic educational system for environmental education, for both pre-service teachers and students.

Stepping into the beginning of the fourth industrial revolution, we need new mathematics education plans and policies to foster talent in people for future. Investigating the present condition and teachers' perceptions of mathematics education in schools is an essential process in making mathematics education plans and policies that reflect the periodical changes and social needs. Thus, we developed a survey to investigate teachers' perceptions and present condition of mathematics education, conducted the survey for teachers in elementary, middle, and high schools, and analyzed the results of the survey. In this study, focusing on the results of the survey, we interpreted the results and provided implications for mathematics educational policies. Through frequency analysis of individual questionnaires and crosstabulation analysis between questionnaires, we could provide mathematics teachers' overall perceptions of mathematics education and basic information on the conditions of mathematics education in the schools. In addition, the findings of this study suggest that policymakers should consider the followings when developing new mathematics education plans and policies: having the proper number of students per class, reducing non-teaching work, supporting teachers' expertise in evaluation, improving Internet access and technology equipment, supporting the school administrators' change of perceptions of mathematics education, retraining teachers in the active use of ICT or technological tools, and supporting students having difficulty learning mathematics.

The purpose of the present study was to verify the relationship between the nursing teachers' perception of infant rights and infant care service. The scale for infant rights consisted of 40 items based on the U.N. convention on the rights of the child and infant care service was measured with 40 items regarding respect of daily life, respect of autonomy, respect of opinion, respect of individualism, and provision of information. The study participants were 489 nursing teachers working at child care centers. According to the nursing teachers' perception of infant rights, the right of survival was highest, followed by the right of protection, the right of development, and the right of participation. The main study results showed that the rights of development and participation were meaningful in predicting various infant care services, but the right of survival was not. This study implies that the difference of nursing teachers' perception on the various types of different infant rights can affect various infant care services.

We have studied possibilities of Peer Instruction(PI) to train in-service science teachers in elementary and middle schools through both degree of conceptual changes and investigating responses to questionaries. 169 teachers were attended and the subject for training was about light propagation to teach scientific conception about a pin hole camera. 6 conceptests were developed. Degree of conceptual changes was analyzed from results obtained from 24 elementary and 32 middle school teachers among them. On the other hand, answers to questionaries were obtained from 135. Relatively high gain near to about 0.7 in conceptual changes was obtained even though their initial levels were quite low. Interesting point is that elementary teachers have higher initial level and larger gain than middle school teachers. Teachers have very much enjoyed and showed strong support to PI for helping conceptual change, and willing to use PI to their own class. Also they conceived dealing concept in teacher training is very important and evaluated PI very positively for teacher training.

This exploratory study reports how teacher-librarians perceive their roles as practitioners in school library media programs. Conducted within the framework of qualitative research, the study employed a focus group interview (Morgan 1997) with five teacher-librarians at elementary school level in Seoul. The findings suggest: (1) the roles of teacher-librarians are influenced a great deal by many factors in educational systems; (2) there is no consensus on how to define and perform their role as teachers; (3) there seems to be increasing emphasis on their program administrator's role; (4) there is no consensus on prioritizing the five roles suggested by the AASL (2009), but all the participants agreed that the leader's role is most crucial for the success of pursuing the rest of the roles, and (5) there seems to be no clear boundaries as teacher-librarians perform their roles. Putting all the results together, the researcher was able to conclude that teacher-librarians are frequently asked to be flexible and negotiable and have great burden in the affective, cognitive, and physical realm for the roles imposed and expected of them.

We investigated whether and how pre-service teachers took the realistic contexts seriously in the course of solving word problems; additionally, we investigated how pre-service teachers evaluated students' realistic and non-realistic answers to word problems. Many pre-service teachers, similar to students, solved some of the realistic problems unrealistically without taking the realistic contexts seriously. Besides, they evaluated students' non-realistic answers higher than the realistic answers. Whether the pre-service teachers could solve problems realistically or not, they did not appreciate students' realistic considerations for the reasons that those were not fitted to the intentions of the word problems, or those were evidence of the flaws of the problem. Furthermore, the analysis of premises implied in the pre-service teachers' evaluation comments showed the implicit didactic contracts about realistic word problem solving that they accepted and also anticipated students to follow. Our analysis of the pre-service teachers' conceptions of realistic word problems can help teacher educators design the teacher program to challenge and revise pre-service teachers' folk pedagogy.
