The purpose of this study was to investigate the elementary school teachers' perception of science writing. In this study, 10 elementary school teachers who have taught in the 3rd or 4th grade science lesson in 2010 were selected. Researchers constructed interview guide in three parts including the teachers' understanding of science writing, the status of science writing teaching and the difficulties of science writing in their classes. For the investigation, semi-structured in-depth interviews with 10 elementary school teachers were conducted individually. The results showed that the elementary school teachers were unfamiliar with the word ‘science writing’ and considered science writing as a writing using science learning contents. Also, they think that teaching science writing in their science lessons was not needed and didn't assess and provide detailed feedback with the students' written works. Most teachers needed teaching materials and assessment tools for science writing. To develop elementary teachers' understanding of the value and use of writing for learning in science, they will need to participate in science writing programs for in-service teachers and various teaching materials and assessment tools should also be developed.

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.

Purpose: The aim of this study was to investigate children's eating behaviors and teachers' feeding practices during mealtime at child-care centers. In addition, it focused on the difference of teachers' feeding practices on children age under 2 years ( ${\leq}2$ years old) and 3 years and older (3~5 years old). Methods: A total of 169 teachers working at childcare centers in Geumcheon-gu, Seoul, Korea, completed self-report questionnaires in December 2013. The questionnaires were composed of questions on children's eating behaviors, feeding practices; 'Explain', 'Praise', 'Modeling', 'Indulgent', 'Insist' and 'Reward', interaction with home, and a range of demographic information (analysis rate: 51.2%). Results: Approximately 59.2% of teachers had not taken a class on feeding practice and the average score for nutrition knowledge was 14.6 out of 30 points. The most undesirable eating behavior of children during mealtime was 'eating while walking around (36.7%)' both ' ${\leq}2$ years old' and '3~5 years old'. Regarding feeding practices according to children's undesirable eating behaviors during mealtime, there were differences between age groups. When children did not eat all of the foods that were served and did not clean up silverware or seats after having food, teachers caring for '3~5 years old' practiced 'Explain'. However, percentages of those who practiced 'Indulgent' and 'Modeling' were significantly higher in teachers caring for ' ${\leq}2$ years old' than '3~5 years old'. Conclusion: These findings indicated that teachers caring for children lack education and knowledge about nutrition and feeding practice. In addition, verbal feeding practices, like explain, were mainly used by teachers. As a result, for teachers, guidelines and programs for learning about age appropriate feeding practice during mealtime at child-care centers may be needed.

일반적으로 자기구성 지도에서는 구조가 초기에 결정되어 학습이 끝날때까지 변하기 않기 때문에 각 문제에 대한 구조를 반복된 실험을 통해서 최적화시켜야 한다. 그러나, 지도의 구조가 학습중에 적절하게 변경된다면, 해당 문제에 가장 알맞은 구조의 지도를 생성할 수 있을 것이다. 이 논문에서는 기존의 적응형 자기 구성 지도의 비교사 학습방법에 LVQ 알고리즘을 이용한 교사 학습방법을 결합한 구조 적응형 자기 구성 지도 모델을 제안한다. 이 방법은 일반적인 자기구성 지도 알고리즘보다 작은 수의 노드를 가지고 높은 성능을 보일 뿐만 아니라, 자기 구성 지도의 특성인 위상 보존도 잘 이루어진다. 오프라인 필기 숫자 데이터로 실험한 결과, 제안한 방법이 유용함을 알 수 있었다.

This study aims to investigate how secondary mathematics teachers use mathematics curriculum materials such as textbooks and teachers' guide in planning lessons and for their learning. 24 in-service mathematics teachers participated in surveys and two among them were interviewed. The findings from the data analysis suggest that: a) the teachers actively engaged in decision-making processes of the transition from written curriculum to intended curriculum; and b) the teachers showed a tendency of consulting to the ideas suggested in the curriculum materials for selecting objectives and contents for lessons and the what to assess, not ideas for selecting teaching methods and how to assess. Also, various factors such as students' achievement, participation, interest in mathematics, family environment, and college entrance were identified to influence the teachers' use of the curriculum materials.

This thesis is to figure out the influences of children's gender, educational level of parents, educational participation of the mother, teaching method of teacher and literacy conditions of home and class on preschool children's school readiness. The objects of this study are 141 preschool children under 5 years old, 141 parents and 42 class teachers. Test for School Readiness, Measure of Mother's Educational Participation, Measure of Teacher's Teaching Method, and Measures of Literacy Condition of Home and Class are used as a studying tool. Collected materials were analyzed by Three-way ANOVA, Correlation analysis of Spearman, product-moment correlation analysis of Pearson, and phased regression analysis. The results are as follows: First, there are meaningful differences between the gender of children and mother's educational level for the school readiness. Second, except for the home's literacy condition, children's gender, educational level of parents, educational participation of mother, teaching method of teacher and literacy conditions of class show the meaningful positive correlation with the children's school readiness. Third, the adaptive zone, which is the subordinated zone, is affected by the gender of children, and the knowledge zone is influenced by the mother's educational level most. These results will be useful for the basic data that can help to promote school readiness for children's parents and teachers.

The 7th curriculum sets a basic direction based on learner centered teaching, with the aim of allowing students to develop their mathematical ability. Teachers' manuals are provided to help teachers fallow the basic direction and achieve the curriculum aims, but in practice they are not always helpful. Therefore, we reconstructed parts of a teachers' manual. This involved analyzing the contents of units 6, 7 and 8 of the elementary mathematics textbook 4 na to identify and outline the problems; introducing more detailed teaching methods and activities; and developing teaching learning materials. We tested the new version in several real classes and analysed the responses 6f teachers and students to examine the possibility of its practical use. The results suggest that the reconstructed version of the teachers' manual for units 6, 7 and 8 of textbook 4 na is of greater practical utility.

수업의 핵심이라고 할 수 있는 교사의 교수법 향상을 위해서는 실제 수업을 잘하는 사람의 수업 장면과 교수 학습 지도안을 보고 동료교사 및 전문가들과 같이 수업에 대해서 같이 토론하는 것이 좋을 것이다. 그러나 현장의 교사들에게는 실제 그러한 참관 기회가 많지 않을뿐만 아니라 참관 및 토론의 환경도 충분히 제공되지 않고 있다. 이러한 문제점을 해결하기 위한 방법으로 실제 교수법이 뛰어나 교사의 수업 장면을 동영상으로 제작하고, 이 동영상과 교수 학습 지도안을 동기화시킨 전자 지도안을 만들어 현장 교사들에게 제공하는 것이 좋을 것이다. 본 연구에서는 교수법 향상을 위해 저자 지도안 재작 도구의 프로토타입을 개발하였다.
