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 examined the effects of teachers' DAP beliefs and teacher efficacy on the conflict resolution attitudes of teachers. The study was based on the survey data from 128 early childhood teachers working in day care centers in the Incheon area. The valuables were all measured by teachers. The collected data were analyzed by Manova and Logistic Regression. The main results of this study were as follows. Firstly, there was a significant difference in collaborating and avoiding types of conflict resolution attitudes according to only age among demographic variables. Secondly, teachers' DAP beliefs and teacher efficacy were positively related to the collaborating type but negatively related to avoiding and competing types of conflict resolution attitudes. Finally, teachers' DAP beliefs and teacher efficacy had positive effects on cooperative conflict resolution attitudes after controling for demographic variables. Our findings indicate that teachers' DAP beliefs and teacher efficacy have effects on their conflict resolution attitudes during preschoolers' peer conflicts.

인지적으로 안내된 교수(CGI)는 학생들의 수학적 사고(특히, 비형식적 지식)의 발달; 그러한 발달에 영향을 미치는 교수; 교수 실제에 영향을 미치는 교사의 지식과 신념들; 교사의 지식, 신념들, 실제들이 학생들의 수학적 사고에 대한 이해에 의해 영향을 받는다는 점에 초점을 둔 통합된 연구 프로그램이다. 본 논문에서는 아동의 비형식적인 지식을 중시하는 최근의 연구들을 고찰하고, CGI를 위한 수업을 어떻게 조직하며, 그러한 교수법이 수업을 어떻게 진행할 것인지에 대한 구체적이고 명확한 지침을 제공하지 않으므로 CGI를 적용하는 교실들의 유사점을 살펴본다. 그리고, 마지막으로 최근의 연구들을 고찰함으로써 CGI의 효과를 알아본다.

This study aims to explore mathematical belief system and core belief factors to be found. The mathematical belief system becomes an auto regulation device for students' using mathematical knowledge in mathematical situations and provides them with the context to perceive and understand mathematics. They have individual mathematical beliefs for each of mathematics subject, mathematical problem solving, mathematical teaching and learning and self-concept, and these beliefs of students construct mathematical belief system according to mutual relationships among the mathematical beliefs. Using correlation analysis and multiple regression, mathematical belief system was structuralized and core belief factors were found. Mathematical belief system is structuralized and, as a result the core belief factors that are psychological centrality of high school students' mathematical belief system are found to be persistence, challenge, confidence and enjoyment. These core belief factors are formed on the basis of personal experiences and they are personal primitive beliefs that cannot be changed with ease and cannot be shared with other people but they are related with many other beliefs influencing them.

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.

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.

In this study, instruments were developed to measure of mathematics attitudes by conceptualization of epistemological beliefs as a cognitive dimension, mindfulness as a conative dimension, affect as an affective dimension. Perry's epistemological development scheme and Langer's mindfulness theory was noticed as a theoretical approach. Exploratory factor and confirmatory factor analyses, and a reliability test were assessed. This article suggest a new framework for analysing attitudes toward mathematics and changes in attitudes toward mathematics.

The purpose of this study is to analyze and evaluate the nature, role and development of pedagogical content knowledge in science teaching. Two research questions were considered: 1) What are the nature and the components of the pedagogical content knowledge in science teaching? 2) What is the value of pedagogical content knowledge and are there any routes and paths to developing pedagogical content knowledge for science teachers? In order to answer these questions instead of analyzing empirical data, former research literatures are reviewed. The results indicate that science pedagogical content knowledge is a special amalgam of science content knowledge and science method knowledge in a special context of science teaching that is uniquely the province of teacher based on their own special form of professional understanding. As a part of one's own distinctive bodies of knowledge, science teachers' pedagogical content knowledge is an important basis for professional development and competent teachers. It is knowledge of how to teach specific content in specific contexts, also it depends on each teachers' distinctive knowledge structure. Pedagogical content knowledge for science teaching is composed of five components: orientations toward science teaching, knowledge and beliefs about science curriculum, knowledge and beliefs about students' understanding of specific topics, knowledge and beliefs about assessment for teaching science, knowledge and beliefs about instructional strategies for teaching science. The development of science pedagogical content knowledge does not start until teachers have acquired a deeply principled conceptual knowledge of content, also it is promoted by the constant use of subject matter knowledge in teaching situations.

This study purposed to examine how emotional intelligence affect undergraduate students' personal agency beliefs. For the purpose, this study conducted a questionnaire survey of 446 undergraduate students in metropolitan area. Data were analyzed by t-test, Pearson's correlation, correlation analysis, and linear regression analysis. The results were as follows. The regulation of emotion of emotional intelligence and capability beliefs of personal agency beliefs were significantly different according to sex and others' emotion appraisal of emotional intelligence and capability beliefs of personal agency beliefs were significantly different according to school level. Also, the others' emotion appraisal of emotional intelligence and capability beliefs of personal agency beliefs were significantly different according to religion existence. There was a correlation between the emotional intelligence and personal agency beliefs. The others' emotion appraisal, regulation of emotion and use of emotion of emotional intelligence have an impact on personal agency beliefs including capability beliefs and context beliefs, the explanation concerning capability beliefs(47%) and context beliefs(22%) was persuasive. Therefore, when undergraduate students have to make career decision for their future, in order to encourage personal agency beliefs which are related to motivational factors, the consequence of emotional intelligence was verified. It is necessary to establish many kinds of supporting systems to encourage the emotional intelligence and personal agency beliefs.

This study examined pre-service secondary physics teachers' epistemological beliefs about scientific knowledge, science learning, and science teaching in two different science content topics, Lamarckism and the impetus theory. Two sets of open-ended questionnaires, for each of the topics respectively, were developed in the same format. The pre-service teachers completed the questionnaires at one month intervals. The beliefs were analyzed in two dimensions, knowledge justification and knowledge change for each belief area. The findings show that the majority of pre-service teachers held sophisticated epistemological beliefs about scientific knowledge regardless of content topics. On the other hand, more pre-service teachers exhibited sophisticated beliefs about science learning in the context impetus theory than Lamarckism. In the area of science teaching, the majority of pre-service teachers demonstrated a sophisticated view in knowledge justification but a naive view in knowledge change. When consistency across science topics and belief areas were examined, few pre-service teachers held consistent epistemological beliefs across all topics and areas. The difference in the levels of sophistication in belief areas showed that the pre-service teachers did not connect their epistemological beliefs about science knowledge to their ideas about science teaching and learning. This disconnection seems to make the consistency across topics and areas complicated. The difference in epistemological beliefs about science learning and teaching between two science topics need further inquiry. Implications for teacher education are offered.
