This study explored the beliefs and practices of Developmentally Appropriate Practice (DAP) in 83 principals and 83 teachers of public and private kindergartens in Pusan and Ulsan. The research instruments was a teacher questionnaire by Kang(2000). Data were analyzed by t-test and ANOVA. Results showed that educational and career variables were unrelated to the DAP beliefs of principals, but there were differences in DAP beliefs by career variables of teachers. Teachers' use of DAP varied as a function of children's age and of combined levels of beliefs of principals and teachers.

The purpose of the present study is to develop instrument of mathematical belief of middle school and high school students and to analysis results of test using the instrument. Based on the results of literature review, mathematical belief is the cumulative effects of self-assessment and self-concept in mathematical learning and achievement experience. Four sub-components of mathematical belief is identified belief of school mathematics, belief of mathematical problem solving, mathematical self-concept, belief of mathematical teaching and learning. The instrument was developed to investigate mathematical belief by reflecting Korean middle school and high school students' psychological characters. To develop the appropriate items for the mathematical belief, after reviewing literature thoroughly, first version of the instrument was developed and exploratory factor analysis and confirmatory factor analysis were conducted. Then, to reduce the effect of the gender difference and achievement level difference, Correlation Analysis and 1-way ANOVA was performed. Also, using multiple group confirmatory factor analysis, this instrument was investigated to see whether this can be used for both middle school and high school. The final items for middle school students is consisted 7 items of belief of school mathematics, 9 items of belief of mathematical problem solving, 11 items of mathematical self-concept, 10 items of belief of mathematical teaching and learning. Instrument of mathematical belief for high school students is consisted 9 items of belief of school mathematics, 9 items of belief of mathematical problem solving, 11 items of mathematical self-concept, 11 items of belief of mathematical teaching and learning. This study examined the differences about mathematical belief's sub-factors shown by three groups of mathematics achievement level. Students of higher achievement level showed that the degree of most factors ware the highest excepting stereotype of belief of school mathematics. Also, Male students preferred more positive in mathematics belief than female students.

For secondary school teachers who attended 'A Social Constructionism Science Teacher Training Program', we analyzed their processes of cognizance change as well as whether they put its results into practice in the field of education, so as to find out the efficacy of the program. 'A Social Constructionism Science Teacher Training Program' consists of three phases based on La main ${\grave{a}}$ la $p{\hat{a}}te$, a French experience-oriented science education program. In its first phase, a study of the philosophy of La main ${\grave{a}}$ la $p{\hat{a}}te$ was made, together with a search for examples of creativity education. In its second and third stages, real education programs were developed for designated themes and free themes, respectively, and then discussions were made. It was a ten-session program, with each session comprising a four-hour sub-program. All activities were both visually and orally recorded, while the participants were asked to write reflective journals for each class. An additional survey and interview were conducted six months later to check if the seven selected secondary school teachers put the results of the program into practice. It was found that changes may be made in the beliefs of teachers with the introduction of theories in teacher indoctrination, but the acquisition of practical knowledge that can be implemented in actual classes may be effectively secured by demonstrations and practice sessions. It was concluded that indoctrination should be conducted to lead participants to the level of practical planning from the level of mere belief so that the theories might actually be put into practice in the education field.

The purpose of this research is to find factors that affect high school science teachers' class compositions. In this research, we developed the class composing factor analysis framework and we observed teachers' class to figure out the class composing factors. The results from this research were as follows: First, the class composing factor was classified with 'positive motive factor' and 'negative motive factor'. It is the positive motive factor that teachers' voluntary motives operate to teacher for class compositions. It is the negative motive factor that outer demands operate to teacher for class compositions. Second, both positive and negative motive factors were shown in all the steps, which included preparing a class, progressing a class, and after a class. Also, according to the circumstances, each factor changed. Minimizing and overcoming negative motive factors will lead to positive interaction between the teacher and students. It will also increase a teachers' achievements in class and maximize the effectiveness of class. Therefore, it is expected that this will be a great help for teachers to enhance their teaching professionalism.

Many students have dualistic beliefs about mathematics and its learning- for example, there is always just one right answer in mathematics and their role in the classroom is receiving and absorbing knowledge from teacher and textbook. This article investigated some epistemic implications and limitations of common mathematics teaching practices, which often present mathematical facts(or procedures) and treat students' errors in a certain and absolute way. Langer and Piper's (1987) experiment and Oliveira et al.'s (2012) study suggested that presenting knowledge in conditional language which allows uncertainty can foster students' productive epistemological beliefs. Changing the focus and patterns of classroom communication about students' errors could help students to overcome their dualistic beliefs. This discussion will contribute to analyze the implicit epistemic messages conveyed by mathematics instructions and to investigate teaching strategies for stimulating students' epistemic development in mathematics.

The study was designed to explore mothers' and teachers' beliefs on children's literacy development by comparing their beliefs with the whole language approach. Also, their literacy practices at home and in the classroom were compared and how their literacy beliefs and practices were related was investigated. 176 mothers and 72 daycare teachers participated in this study in Kyunggi-do. Mean, standard deviation, frequency, t-test, and multiple regression were employed to analyze the data. The results showed that the mothers' age, mothers' education, fathers' education and family income mostly predict the mothers' literacy beliefs. Also the teachers' age, education, and their learning experiences with the whole language approach are the main predicting variables in the teachers' beliefs. In practices, the mothers' age, number of children, and fathers' education are independent variables predicting the mothers' practices. The teachers' age, education, interest about the whole language approach, learning experience, and number of children in the classroom are independent variables into the teachers' practices. Overall, teachers showed a higher level of beliefs on the whole language approach and did more literacy practices than the mothers.

The traditional teaching-learning in mathematics, which pursue only one correct answer, should be reexamined to cope with an age of uncertainty. In this research, Perry's epistemological development scheme was noticed as a theoretical approach to diagnose problems of dualistic mathematics lessons and to search solutions of the problems. And Design-Based Research method was adopted, We developed the epistemological development scheme through considering Perry's theory and related studies, scaffoldings and teaching-learning to enhance students' epistemological positions in mathematics. Based on these discussions we designed teaching experiment about operations with negative numbers, and analyzed its didactic implications.

This study investigated how the unique educational contexts in the Republic of Korea (RK) impacted two science teachers' teaching practices in a public middle school and what the science teaching experience means to them. In particular, we explored how the middle school science teachers decide pedagogical approaches to use in their teaching based on classroom climate, students' attitude toward learning science, school curriculum and classroom culture. Using a phenomenological research approach, we analyzed classroom observation data and interview data to interpret the teachers' science teaching experience. Results of the study showed that the teachers' practice was dominantly affected by two external factors. First, the teachers' teaching practice was affected by the amount of science content knowledge they need to cover within a given class time. Second, the teachers' teaching practice was affected by students' attitudes toward science learning and their science preparedness in private tutoring centers. Implications of the study results are discussed in the paper.

This study identified and explained the prototypes of teacher's belief about children's play with the use of Stephenson's Q-methodology. The sample consisted of 35 kindergarten teachers. A Q-deck composed of 48 cards, derived in part from a review of related literature and was developed by the researchers and sorted by the subjects. The obtained Q-sort scores were analyzed by factor analysis. The findings revealed that the subjects were divided into 3 belief types : "life-experienced", "developmental-disciplinary", "cultural-environmental". Likely explanations for these results are considered, and implications are discussed.
