This attitudes scale for prediction of mathematics achievement by elementary school students was developed from 50 initial items from the literature rated for content validity by 30 experts. The ratings rendered 31 revised items used for exploratory factor analysis and reliability tests. The 31 items were administered to 183 elementary students in 4th, 5th, and 6th grades, yielding 4 factors : enjoyment, confidence, value, and motivation with high inter-items consistency. To confirm appropriateness of the constructed model and to test its predictability in mathematics achievements, confirmative factor analysis and discriminant analysis were performed on 693 cases. Results showed that the attitude scale model of 4 factors can be recommended for use in the measurement of elementary school students' attitudes toward mathematics.

본 연구는 4D프레임 교구를 활용한 유아수학활동이 만 5세 유아의 수학적 능력과 태도에 미치는 영향을 알아보기 위해 수행되었다. 이를 위해 S시에 위치한 E, K, Y유치원의 만 5세 유아 56명을 실험집단(I: n=14, II: n=14)과 비교집단(III, n=14, IV, n=14)으로 나눈 후 8주 동안 실험집단에서 4D프레임 교구를 활용한 유아수학활동을 실시하였고 비교집단은 각각 누리과정에서 제시하는 수학활동과 수 과학 통합프로그램을 실시하였다. 실험집단(I, II)과 비교집단(III, IV)의 사전검사 점수를 공변인으로 하여 공변량분석(ANCOVA)을 실시한 결과, 4D프레임 교구를 활용한 유아수학활동이 실험집단과 비교집단 간 통계적으로 유의미한 차이가 있는 것으로 나타났고 이는 4D프레임 교구를 활용한 유아수학활동이 유아의 수학적 능력과 수학적 태도의 향상에 긍정적인 영향을 준 것으로 해석할 수 있다. 본 연구를 통해 유아교육 현장에서 4D프레임 교구를 활용한 유아수학활동의 효율성을 이해함으로써 유아들의 수학적 능력 및 태도의 향상을 위한 현장 적용 가능한 교육적 방안을 위한 기초자료를 제공하고자 한다.

This study was designed to examine the effect of five years old boys' and girls' self-concept and leadership on the teacher-child relationship. The participants were 51 boys and 64 girls who were five years old in Jeonrabukdo. The results were as follows. First, in the case of the boys, there was significant relationship between their self concept of language, the parent relationship and an intimate teacher-child relationship. The self-concept of body and the teacher-child relationship of conflict were positively correlated. In the case of the girls, there were significant relationships between the self concept of body, language, the parent relationship, friends' relationship and the general and intimate teacher-child self-concept. The self-concept of mathematics and conflictive teacher-child relation were positively correlated. Second, there were significant relationships among the sub variable of leadership and an intimate teacher-child relationship. However, prosocial leadership, directedness and a conflictive teacher-child relationship were negatively correlated in the case of the boys. Third, the teacher-child relationship was affected by leadership more than the self concept, and prosocial leadership was highly related in boys and girls.

Thomas Harriot has been introduced in middle school textbooks as a great mathematician who created the sign of inequality. This study is about Harriot's symbolism and the theory of equation. Harriot made symbols of mathematical concepts and operations and used the algebraic visual representation which were combinations of symbols. He also stated solving equations in numbers, canonical, and by reduction. His epoch-making inventions of algebraic equation using notation of operation and letters are similar to recent mathematical representation. This study which reveals Harriot's contribution to general and structural approach of mathematical solution shows many developments of algebra in 16th and 17th centuries from Viete to Harriot and from Harriot to Descartes.

본 연구는 TV 애니메이션 '똑똑박사 에디'의 스토리텔링 요소와 수학내용을 분석하는데 목적이 있다. 선행 연구와 문헌을 토대로 설정한 분석기준에 따라 시나리오와 애니메이션을 보면서 내용분석과 빈도분석을 실시하였다. 연구결과를 제시하면 첫째, 의인화된 11명의 동물이 등장인물로 나오며, 에디는 주인공으로서 문제해결자의 역할을 담당한다. 등장인물의 말, 행동, 사고양식은 전조작기 유아의 수준으로 묘사된다. 눈 덮인 숲 속 마을을 배경으로 일상적이고 평범한 스토리가 진행되며, 중심서사는 있으나 이야기는 플롯의 형식으로 구성되어 있지 않다. 이야기의 주 내용은 수학내용을 다루고 있으며, 에피소드는 대화, 노래, 나레이션을 통해 진행된다. 둘째, 애니메이션에서는 1회당 평균 23회의 수학내용을 다루고 있으며, 수감각, 기하, 측정, 자료분석과 확률, 규칙성의 순으로 나타났다. 이로서 '똑똑박사 에디'는 에듀테인먼트로서의 가치가 있는 작품으로 평가할 수 있다.

The radical development of modern mathematics is due to the appearance of Collection Theory by George Cantor. The Set Theory is independent as an area and also closely interrelated with other areas. So its content becomes a common sense and a basic part across the whole area of modern mathematics. Accordingly, the basic element of modern mathematics is helping young children get familiar with set as early as possible. The thinking of set by which children can categorize, make partial sets and correspondences, understand the general characteristic, and conceptualize the discovered relationships is very important for young children. At this point where the Math education for young children is emphasized under the influence of the modernization movement of Math education, the systematic education for building up the set concept as the basic background of number concept during the early childhood is required. On current mathematics education for young children, graphs, the foundation of geometry, time, and patterns have been included in the traditional and practical content related to numbers. However, the education on collection which is the foundation of number concept is insufficient. A study shows that the level of young children's understanding on set is quite high, but the set concept isn't reflected in current Math curriculum for young children. And basic activities neccesary on building up the set concept, such as categorization, comparison, etc. are conducted in kindergardens but unsatisfactory because of those kindergarden teachers' premature understanding on the set concept. In conclusion, the curriculum for young children should be reorganized based on the set concept as the kernel concept. Also, the reappraisal of the training curriculum and the supplementary efucation for kindergarden teachers are urgent for raising the teaching ability of those kindergarden teachers.

The purpose of this study was to better understand the tendencies and general distributive features of mathematical educational activities which are presented in the Nuri Curriculum Teaching Guidebooks. This was done by analysis of 628 mathematical activities suggested in those guidebooks, the total number of which was thirty-two. The results of this study can be summarized as follows: First, the number of activities for mathematical education was 204 for the age of three, 223 for the age of four, and 201 for the age of five. Second, these mathematical educational activities are aimed mainly for developing positive attitudes toward mathematics rather than the delivery of mathematical knowledge and skills. Third, the number of activities for developing mathematical inquiry skills was greater than that of activities for developing of inquiry attitudes. Furthermore, the characteristic of understanding the basic concepts of space and figures can be found most frequently in five kinds of activities for mathematical inquiry. Last, the activities for mathematical education are more frequently found in free choice activities rather than group activities. The results of this study also suggest that checking the current status of mathematical education for young children and the Nuri Curriculum Teaching Guidebooks can be utilized for creating teachers' manuals.

고대 그리스에서 발현된 수학의 무한 개념은 헤브라이인의 유대교 전통인 카발라의 영향을 받아 중세 기독교 교부 철학자들에 의해 보다 성숙되어져 갔으며, 그 후 기독교의 무한사상이 르네상스 시대에는 화가들에 의해 원근법으로 구체화되었다. 본 논문에서는 그리스 시대부터 발전된 무한 개념의 경로를 살펴보고, 근대와 19세기 이후 무한수학이 발달될 때 당시 미술에서는 무한 개념이 어떻게 표현되었는지 그 시대정신을 고찰한다.

This study examined the effects of estimation activities on children's operation and measurement abilities. Subjects were 60 five-year-old children. This experiment used the untreated control group design with pretest and posttest. Instruments used to collect data were the Number and Operation and Measurement tests part of the Test of Mathematics Ability for Young Children (TMAYC) developed by Hong, Lee and Chung (2006). ANCOVA was employed for statistical analysis. Results of the posttest showed that children in the experimental group scored significantly higher on children's operation and measurement abilities than the control group. Results imply that an estimation program can be an effective teaching model for improving children's operation and measurement abilities.
