이 연구는 우리나라 초등예비교사의 수학의 본질 및 수학 학습에 대한 수학적 신념 및 수학적 신념의 범주별 관련성을 알아보는 데 목적을 두었다. 이를 위해 4개 교육대학교 수학교육과에 재학 중인 1, 2, 3, 4학년 초등예비교사 399명(여학생 283명, 남학생 116명)의 수학적 신념에 대한 자료를 수집하였다. 설문조사에 사용된 문항은 2008년에 실시한 TEDS-M의 신념 관련 연구에 사용하였던 설문지를 국문으로 번역하여 사용하였으며 성별, 학년별, 교육대학교별로 나누어 분석하였다. 또한, 수학의 본질에 대한 신념 사이의 상관 관계를 분석 하였다. 먼저 일원분산분석을 통하여 신념이 각 그룹별로 통계적으로 유의미하게 다른지를 살펴보았으며, 그 후 Duncan의 사후 검증 및 Tukey의 HSD 사후 검증을 실시하여 분석하였다. 연구결과, 예비교사들의 수학의 본질에 대한 신념은 수학이 이미 만들어진 결과인 지식과 절차로 보는 것보다는 탐구의 과정이 수학적 본질에 더 가깝다고 생각하고 있는 것으로 드러났다. 수학학습에 대한 신념 측면에서 연구에 참여한 예비교사들은 '교사지시'에 대해서는 교수 행위로 바람직하지 않다고 보는 반면, 학생들의 주도적 학습에 대해서는 바람직한 것으로 보는 경향이 있었다. 초등 예비교사의 수학적 신념의 범주별 관련성에서 수학을 '탐구의 과정'으로 보는 신념과 수학의 학습이 '주도적 학습'이어야 한다는 신념이 통계적으로 유의미하게 관련되어 있고, 수학을 '규칙과 절차'로 보는 신념과 수학의 학습은 '교사 지시'여야 한다는 신념이 통계적으로 유의미하게 관련이 있는 것으로 나타났다.

The objectives of the current study are first, to compare and analyze the two different teaching methods of elementary mathematics in the traditional method and in the constructivists view, and, second, thereby to reveal possible problems of the present teaching practice and to suggest some guidelines to solve those problems.The results of this research are as follows: First, longer time was spent to reach the target pont of class because the class was a little bit disturbed and noisy due to a large amount of student activities in the beginning of the class in the constructive view. Second, in the class in the constructive view, the teacher should be able to respond appropriately to the situation where the students were cognitively. And the teachers sufficient preparation for the class was found essential to have the students reach the target point by themselves through identifying children`s minds. Third, the class in the constructivists view provide the teaching environment were the teacher could evaluate each students ability accurately and study progress of the class. And fourth, finally, it was not easy for the teacher to pay attention individually to each student in the current situation of large class, The effort to have more concern for students seems to contribute to opening student`s closed minds and to forming positive attitudes toward mathematics.

수학교육은 교육과정과 같은 제도와 그것을 반영하는 교과서 등의 도구로 이루어진다. 그러한 제도나 도구는 인간이 만든다. 그러므로 그것들을 만드는 사람의 수학관은 중요한 요소로 작용한다. 수학관은 수학을 하고, 배우는 동안에 형성되지만, 형성된 수학관은 수학을 하고 가르치는데 영향을 미친다. 따라서 수학교육에 관계된 사람들이 어떠한 수학관을 가지고 있느냐 하는 것은 중요한 요인이다. 이 글은 수학관으로서 변증법적 유물론에 입각한 관점을 제시한다. 수학의 발달과정과 그 결과에 변증법적 유물론이 관철되고 있다. 곧, 수학 지식은 양질전화, 대립물의 통일과 투쟁, 부정의 부정이라는 변증법적 유물론의 기본 법칙에 따라 발전해왔다. 수학에 대한 이러한 관점은 수학을 절대주의적, 상대주의적으로 보는 것과 다른 수학교육의 관점을 제공할 것이다. 이 글은 수학을 유물론의 관점과 변증법의 관점으로 분리하여 살폈다. 분석의 편의를 위해 그렇게 하였을 뿐이다.

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.

This research is a survey study on students' attitude toward a class employing small group discussion and presentation by the method of free-listing. Participants in this study were students who registered in the course of Mathematical Logics and Writing during 2011 and 2014. Senior students who took the course of theory of mathematics education previously usually registered the course. The class for this course used to be designed as a class adopting group discussion and presentation. Main theme of this research is not to demonstrate some theories or hypothesis on teaching and learning, but rather to inquire students' attitude toward a class employing the constituents first and then through analyzing the results of this study to find practical ideas and strategy for design and implementation of a class which brings cultivation of students' understanding, communication and moreover writing in mathematics. Since the survey was given in the $8^{th}$ week of this class, participants of this research could be expected to have more concrete idea for positive or negative aspects of the classes employing these constituents. We compared both research results of 2011 and 2014 to view any changes in students' attitude. Research results are follows. Students began to think that group discussions and presentation bring out better learning to them. Not to give students psychological burden of discussion and presentation, instructors need to provide comfortable atmosphere through arranging suitable grouping and enough time for discussion. Moreover, simple evaluations criteria for group discussions and presentation should be well structured and more concrete guides for them are required to make students to feel comfortable and to concentrate on the given subject for discussion.

Practice of proof is considered in, the view of language and meta-mathematics, recognizing the role of proof that is the means of communication and development of mathematical understanding. Linguistic components in proof texts are symbol, verbal language and visual text, and contain the implicit knowledge in the meta-mathematics view. This study investigates the functions of linguistic elements according to Halliday's functional grammar and the rhetoric skills in proof texts in math textbook, teacher's note, and student's written text. We need to inquire into the aspects of language for mathematics learning process and the understanding and use of students' language.

Measurement has been an important part of mathematics content students must learn through their schooling. Many studies suggest students' weak measurement learning, particularly related to length measurement, on the part of lower grade students. This difficulty has been attributed to mathematics curriculum as well as instruction. Building on a view of teaching as an interactive activity, this paper explores how a first grade teacher interacted with her students in small groups in a length measurement lesson to promote conceptual understanding as well as procedural fluency. I found that even though the teacher supported students to explain and justify what they understood, the ways the teacher interacted with students were not effective to promote students' understanding. Even though this finding is based on an analysis of a single mathematics lesson, it provides an example of challenges in promoting students' understanding through interaction with students in the context of teaching length measurement.

Spatial ability has been valued as a talent domain and important skill in mathematics education because it enhanced an intuitive view and an understanding in many areas of mathematic. In addition, spatial ability highly correlates with mathematics achievement, indicating its crucial role in success in mathematics education. Some researchers founded gender differences in mathematics and spatial ability, and indicated that spatial ability served as a mediator of gender difference in mathematics. This study explored the spatial ability of 349 Korean middle school students (Grade 7-9), and investigated the association among students' spatial ability and their mathematics achievement, gender, and grade. The result of this study shows that spatial ability correlates positively with mathematics achievement. While gender difference did not exist in mathematics, significant gender difference existed in spatial ability favoring male students.

Anecdotes can produce an emotional and simple response that decreases stress and anxiety in a classroom. The use of anecdotes in building concepts of statistics can support an effective way of teaching and learning statistics. Particularly, we demonstrate several anecdotes including pictures as the medium of image that are designed to motivate statistical ideas by placing them at the beginning of a lecture and by appealing to prospective teachers weighed down. Our purpose is that under the constructivist view, prospective teachers have an opportunity effectively to teach statistical concepts using humorous anecdotes and to experience significant beliefs on identifying some frequent misconceptions in statistics. At this procedure, the anecdotal teaching practice is concerned with describing and evaluating many humorous anecdotes we have found useful in teaching introductory statistics. We hope that this paper can be helpful to prospective teachers who will teach students such topics as descriptive statistics, sampling, and hypothesis testing.
