This study examined the relationships between the cognitions and strategies of child's problem behaviors depending on the level of preschool teacher's professional development. Participants were 176 preschool teachers in B Metropolitan city. The teachers completed rating scales to measure teacher's professional development, the perception of child's problem behaviors, and teacher's guiding strategies for child's problem behaviors. The collected data were analyzed using descriptive statistics, one-way ANOVA, and Pearson correlations. Results showed that there were different cognitions of child's problem behaviors depending on the level of teacher's professional development. Secondly, child's problem behavior guiding strategies by the level of teacher's professional development were significant differences in the positive prevention strategy I, II, and the positive reaction strategy. Finally, there were somewhat different relationship between the cognition of child's problem behaviors and the problem behavior guiding strategies according to the level of teacher's professional development. Findings are discussed in terms of the importance of teacher's professional development in the context of teacher's education planning for teacher's guiding strategy about preschooler's problem behavior.

The purpose of this study was to examine the effects of young children's stay hours on kindergartens or child care centers on their language, cognition, and social development with teacher-child interactions as a mediator. For this purpose, the data from the 2013 Panel Study on Korean Children were analyzed using the GLM and pattern analysis. The results of the GLM analysis were as follows. First, the main effects of the stay hours on child development were statistically significant Second, the main effects of the level of teacher-child interaction were also statistically significant on the results of child development. Third, the moderating effect of teacher-child interaction level between the stay hours and child development were also significant. The results showed that young children's stay hours effected their language, cognitive, and social development and teacher-child interactions mediated these effects.

Cognitively Guided Instruction (CGI) is one of the most successful professional development programs for elementary mathematics teachers in US. This article introduces its theoretical background, research-based framework of addition and subtraction work, and how the program has been disseminated. Carpenter and Fennema started CGI aiming to develop a professional development program that focused on research knowledge of children"s thinking. Their goal was. to bring a significant change in teaching by helping teachers understand how children think mathematically. This 3-year NSF funded project grew to be 11-year long, and a number of publications have reported consistent successful learning and teaching by CGI students and teachers compared to counterparts throughout US. CGI′s success by focusing on improving teachers′ knowledge of children′s thinking offers possible opportunities for teacher educators to re-conceptualize teacher education in Korea.

The purpose of this study is to examine not only students' cognition in the mathematical error-finding activity of the concept of irrational numbers, but also the students' learning stance regarding the use of errors and a teacher's questioning strategies that lead to changes in the level of mathematical discourse. To this end, error-finding individual activities, group activities, and additional interviews were conducted with 133 middle school students, and students' cognition and the teacher's questioning strategies for changes in students' learning stance and levels of mathematical discourse were analyzed. As a result of the study, students' cognition focuses on the symbolic representation of irrational numbers and the representation of decimal numbers, and they recognize the existence of irrational numbers on a number line, but tend to have difficulty expressing a number line using figures. In addition, the importance of the teacher's leading and exploring questioning strategy was observed to promote changes in students' learning stance and levels of mathematical discourse. This study is valuable in that it specified the method of using errors in mathematics teaching and learning and elaborated the teacher's questioning strategies in finding mathematical errors.

The purpose of the study was to examine the effects of preschool teachers' qualification (education level, teaching experience, major, and certification) and competency variables (teaching efficacy and teacher-child interaction) on young children's development (cognition, language, and social development). The data came from $5^{th}$ Wave of Panel Study on Korean Children (PSKC) from the Korea Institute of Child Care and Education, and the multiple regression analyses as well as Pearson's correlation analyses were used. The results showed the positive associations between teachers' competency (teaching efficacy and teacher-child interaction) and child development. However, we did not find significant effects of teachers' qualification on young children's development. Based on the results, we proposed a policy implication that teacher qualification needed to be discussed with teacher competency to improve teacher quality.

The purpose of this study is to survey mathematics teacher's cognition of proof along with their proof forms of expression and proof ability, and to explore the relationship between their proof scheme and teaching practice. This study shows that mathematics teachers tend to regard proof as a deduction from assumption to conclusion and that they prefer formal proof with mathematical symbols. Mathematics teachers also recognize that prof is an important area in school mathematics but they reveal poor understanding of teaching methods of proof. Teachers tend to depend on the proof style employed in mathematics textbooks. This study demonstrates that a proof scheme is a major factor of determining the teaching method of proof.

The purpose of this research is to examine childcare teacher's cognition of human right awareness for handicapped children and consciousness of social integration. The subjects were 209 kindergarten teachers in G city. The collected data were analyzed by descriptive statistics, correlation, and regression analysis with SPSS ver. 14.0. The results are as follows: Among the childcare teacher's awareness about children with disabilities human right, awareness of right to survive, right to be protected, right to participate, and right to development had direct effects on their consciousness of social integration. Among the social supports influenced by childcare teacher's awareness of human right, informational support and material support had both direct and indirect effects on their consciousness of social integration. Therefore, as childcare teachers' awareness of human right is an important factor for their consciousness of social integration, a systemic human right education for human right awareness should be provided, the necessity of establishing various social support system should be recognized to foster the social environment of respecting young children's human right, and human right awareness should be practiced into action in daily life, in order to help childcare teachers to develop as the main agents of children's human right.

Prospective teachers need to have an opportunity to critically examine their initial perception with regard to effective mathematics instruction during the teacher education period. This study analyzed the perception in relation to good mathematics instruction by a total of 265 prospective teachers from four institutes for elementary teacher education using a survey. The results of this study showed that the pre-service teachers regarded learner, teaching and learning method, selection of content, and construction of curriculum as important for high-quality mathematics instruction. However, they revealed relatively low levels of agreement against the importance of instructional materials, classroom environment and atmosphere, and assessment. On the basis of teachers' perception on each element of effective mathematics instruction, this paper raises issues for discussion and includes some implications for teacher education.
