평가는 수학 교실에서 의미 있게 활용된다. 최근 대부분의 수학교실에는 교수 학습이 결합된 수행평가가 도입되고, 또 평가는 많은 사람들(학생, 교사, 학부모, 행정가)의 관심을 받고 있다. 그러나 수학교실의 수행평가에도 불구하고 일부 교대생은 임용시험에 대한 불안 때문에 학원을 찾고, 또 일부 강좌에는 그러한 학생들의 불안을 외면할 수 없게 되었다. 왜냐하면 학생의 불안을 외면한 수행평가는 자칫 공허해지고, 또 그들의 수학적 힘을 효율적으로 증진할 수 없기 때문이다. 본고는 초등교원 임용시험(2010)을 수학 심화과정 관점에서 접근하고자 한다. 본 연구 결과는, (1) 초등교원 임용시험 기간은 단축되어야 한다. (2) '어법 원고지 사용법'은 수학적 관점에서 접근되어야 한다. (3) 교대생 시험불안은 임용시험보다는 합격자 수감축에서 비롯된다. (4) 영어 교과의 비중은 재고되어야 한다.

The purpose of this study is to investigate how fifth and sixth graders recognize average and to find out suggestions for teaching/learning methods of average by examining which difference there is depending on the way of the word problem presentation. To solve these study questions, With the way of the word problem presentation set up as experimental treatment experiment was conducted to analyze these. In conclusion, since students who did not learn the regular course of average values had various informal concepts already, it is needed to consider handling more various concepts of average in order to enable students to expand flexible thoughts. And informal concepts of average students showed were the same or similar to types of formalized concepts and had logicality and propriety in their own way. Compared with fifth graders, sixth graders showed a wide difference in informal concepts of average depending on the way of the word problem presentation.

The purpose of this study is to find oui the effects of teaching mathematical concepts by designing and applying teaching and learning programs that takes into consideration the students' strong intelligence, through the teaching and learning strategies based on the multiple intelligences theory. For this study, developmental and experimental research was conducted. In the developmental research part of the study, teaching and learning programs for teaching the concept of multiplication were designed and the activities based on the multiple intelligences were chosen. On the other hand, in the experimental research part, the data acquired from the application of nonequivalent control group pretest-posttest design in the actual classes was processed and analyzed. The results above indicate that the teaching and learning program based on the multiple intelligences theory improved the students' overall understanding of mathematical concepts by providing various types of activities. In addition, this program helped students to increase their confidence and generate a positive attitude towards learning math.

수학적 모델링 활동은 실생활에서 마주할 수 있는 상황을 수학적 모델로 변환하여 문제를 해결하는 과정으로 다양한 측면의 활용이 기대되고 있다. 수학적 모델링 활동에 대한 학생들의 인지적, 정의적 및 사회적 측면을 분석하기 위하여 초등학교 5학년 학생 10개 모둠을 대상으로 수학적 모델링 활동을 진행하고 과정 및 결과를 분석하였다. 활동 결과, 각 모둠은 실생활과 관련된 과제를 해결하기 위해 수학적인 모델을 만들고 필요한 정보를 수집하는 과정에서 수학적 개념과 원리를 적용하였다. 흥미, 수학적인 성취감 및 수학에 대한 태도에 대한 변화가 관찰되었으며 모둠원 간 협업, 의사소통을 경험하였다. 분석 결과를 바탕으로 효과적인 수학적 모델링 활동을 위한 교수학적 시사점 및 지도시 유의점을 제시하였다.

Whole number concept is an important part of mathematics learning. Elementary school students should understand and master whole number concept. Models can help students learn whole number concepts. Realistic Mathematics Education in Netherlands had investigated and developed three different structural models: line model, group model, combination model. These models are related whole number concepts and structures closely and compatible. The purpose of this study is to investigate models related with whole numbers in 7th elementary textbooks. As a result of analyses, we found out some pattern and several problems. On the foundation of the analyses, we discussed the better ways of using models in teaching whole number and the research issues concerning these.

The purpose of this paper is to present a specific set of home teaching methods in hopes to prevent slow learner of the elementary mathematics. This paper deals with the number and operations, one of five topics in the elementary mathematics A survey of two hundred elementary school teachers was made to see the teacher's opinions of the role of home studying and to concretize the contents of the research topics. There were asked which is the most essential contents for the concrete loaming and which is the most difficult monad that might cause slow leaner. And those were found to be; counting, and arithmetic operations(addition and subtraction) of one or two-digit numbers and multiplication and their concepts representations and operations(addition and subtraction) of fractions. The home teaching methods are based on the situated learning about problem solving in real life situations and on the active teaming which induces children's participation in the process of teaching and learning. Those activities in teaching each contents are designed to deal with real objects and situations. Most teaching methods are presented in the order of school curriculum. To teach the concepts of numbers and the place value, useful activities using manipulative materials (Base ten blocks, Unifix, etc.) or real objects are also proposed. Natural number's operations such as addition, subtraction and multiplication are subdivided into small steps depending upon current curriculum, then for understanding of operational meaning and generalization, games and activities related to the calculation of changes are suggested. For fractions, this paper suggest 10 learning steps, say equivalent partition, fractional pattern, fractional size, relationship between the mixed fractions and the improper fraction, identifying fractions on the number line, 1 as a unit, discrete view point of fractions, comparison of fractional sizes, addition and subtraction, quantitative concepts. This research basically centers on the informal activities of kids under the real-life situation because such experiences are believed to be useful to prevent slow learner. All activities and learnings in this paper assume children's active participation and we believe that such active and informal learning would be more effective for learning transfer and generalization.

The purpose of this study is to analyze the 6th graders' understanding of the concepts of variable on various aspects of school algebra. For this purpose, the test of concepts of variable targeting a sixth-grade class was conducted and then two students were selected for in-depth interview. The level of mathematics achievement of the two students was not significantly different but there were differences between them in terms of understanding about the concepts of variable. The results obtained in this study are as follows: First, the students had little basic understanding of the variables and they had many cognitive difficulties with respect to the variables. Second, the students were familiar with only the symbol '${\Box}$' not the other letters nor symbols. Third, students comprehended the variable as generalizers imperfectly. Fourth, the students' skill of operations between letters was below expectations and there was the student who omitted the mathematical sign in letter expressions including the mathematical sign such as x+3. Fifth, the students lacked the ability to reason the patterns inductively and symbolize them using variables. Sixth, in connection with the variables in functional relationships, the students were more familiar with the potential and discrete variation than practical and continuous variation. On the basis of the results, this study gives several implications related to the early algebra education, especially the teaching methods of variables.

본 연구는 수학적 연결성 구현에 대한 초등 교사들의 인식과 실태를 살펴보고자 지역별 학교 수에 비례하여 층화 군집 표집을 실시하여 28개 학교, 567명의 교사들의 설문지를 분석하였다. 그 결과 수업에서 구현할 수학적 연결성으로 사회적 연결성에 비해 지적 연결성에 대한 인식이 높았으며, 지적 연결성 하위 내용 중에는 실생활과의 연결에 대한 인식이 높았고 실제 수업에서도 가장 많이 구현한다고 응답하였다. 연결의 방법으로는 다양한 연결을 사용하였으나 추론, 학생들의 활동 결과 반영 등의 방법에 활용도가 낮았고 지원을 필요로 하는 자원으로는 실제 수업 사례에 대한 요구가 많았다. 이러한 교사들의 인식을 바탕으로 수업에서 수학적 연결성을 구현하는 방안에 대한 시사점을 제공하고자 한다.

Fairy-tales give students opportunities to build connections between a problem-solving situation and mathematics as well as to communicate solutions through writing, symbols, and diagrams. Therefore, the purpose of this paper is to introduce how to use fairy-tales in elementary mathematics classroom in order to develope student's mathematical concepts and process in terms of the following areas: ⑴ reconstructing literature ⑵ understanding concepts ⑶ problem posing activity. To be useful, mathematics should be taught in contexts that are meaningful and relevant to learners. Therefore using fairy-tales as a vehicle to teach mathematics gives students a chance to develope mathematics understanding in a natural, meaningful way, and to enhance problem posing and problem solving ability. Further, future study will continue to foster how fairy-tales literatures will enhance children's mathematics knowledge and influence on their mathematics performance.
