Isik & K$_1$l$_1$c (1998: Mathematics Education and its Appraising in the Primary School Teacher Certificate) found that many prospective mathematics teachers for primary schools who attended at newly established certificate programs made significant misconception on mathematics education because they were not graduates of education faculties. The levels of conceptual knowledge and procedural knowledge of students from a secondary school in Erzurum, Turkey were investigated in order to reveal how serious misconception the teachers have been made so far. The conceptual knowledge is very important to students, however in this research, it was found that procedural knowledge was much more important than conceptual knowledge.

This paper is to give a brief introduction to a new discipline called 'conceptual metaphor' and 'mathematical metaphor(Lakoff & Nunez, 2000) from the viewpoint of mathematics education and to analyze the metaphors at 4th graders' mathematics classroom as a case of conceptual metaphors. First, contemporary conception on metaphors is reviewed. Second, it is discussed on the effects and defaults of metaphors in teaching and learning mathematics. Finally, as a case study of mathematical metaphors, conceptual metaphors on the concepts of triangles at 4th graders' mathematics classrooms are analyzed. Students may reason metaphorically to understand mathematical concepts. Conceptual metaphor makes mathematics enormously rich, but it also brings confusion and paradox. Digging out the metaphors may lighten both our spontaneous everyday conceptions and scientific theorizing(Sfard, 1998). Studies of metaphors give us the power of understanding the culture of mathematics classroom and also generate it.

본 연구는 개념적 은유의 분석을 통해 RME 기반 대학 미분방정식 수업에 참여한 학생들의 개념적 모델의 변환을 탐구하였다. 분석 결과 학기초 이산적이고 양적인 개념적 모델이 학생들의 수학적 토의 맥락에서 지배적이었으나 맥락문제탐구에 기반한 수학적 의미의 재조정 과정을 통해 연속적이고 질적인 사고를 반영하는 개념적 모델이 발생하여 기존의 개념적 모델이 확장됨이 밝혀졌다. 이와 같은 개념적 모델의 변환은 본 프로젝트 교실 참여가 학생들의 미분방정식에 대한 문제해결적 사고의 유연성을 증대시키는데 기여하였음을 보여준다. 이와 같은 분석 결과에 기초하여, 본 논문은 학생들의 개념적 모델의 변환을 촉발한 교수학적 요소에 대한 논의를 통해 학생들의 개념적 모델 변환이 가지는 사회문화적 의미를 조명하고 RME 기반 수학 수업 모델의 학교 현장 적용에 유용한 시사점을 제공하였다.

기하학의 기본용어인 점과 선에 대한 유클리드의 사전적 정의에서 힐베르트의 수학적 정의 개념으로의 변화과정을 살펴보았다. 이러한 수학에서의 정의 개념 변화의 인식론적 배경은 바로 수학적 대상의 존재 방식에 대한 실재론, 개념론을 거쳐 유명론에 도달하는 철학적 인식의 변화이다.

Using computer technology in teaching school mathematics creates new instructional environments. The emphases on the use of computer technology in the classrooms and in particular the use of computer-based exploration as a context of mathematics instruction have been reflected in the recommendation of the NCTM (Curriculum and Evaluation Standards for School Mathematics, 1989). Although the power of using computer technology in the exploration of mathematical problems has been recognized and stressed by many educators, we do not have many research studies on mathematics in computer-based explorations. Especially research has failed to clarify how computer technology can contribute to the construction of procedural and conceptual knowledge of mathematics. Up to now most researches on procedural and conceptual knowledge in computer environments have only focused on classifying programming languages which program language has more random access and rich interrelationship characteristic in relation to conceptual knowledge in humans, and which computer language has more characteristic flavor of procedural knowledge. How computer-based explorations affect the knowledge construction of mathematics, therefore, emerges as an issue of research on teacher education program for theoretical framework. This situation leads to do research on the effectiveness of using computer explorations in pre-service teacher education in terms of procedural and conceptual knowledge construction.

The purpose of this study was to investigate the effects of using graphing calculators on students' understanding of the linear and quadratic function concepts. The populators of this study are tenth graders at high school in Seoul, one class for the treatment group and another class for the comparison group, and experiment period is 14 weeks including two weeks for school regular exams.Function tests used in the study was proposed which described a conceptual knowledge of functions in terms of the following components: a) Conceptual understanding, b) Interpreting a function in terms of a verbal experission, c) Translating between different representations of functions, and d) Mathematical modeling a real-world situation using functions. Even though the group test means of the individual components of conceptual understanding, interpreting, translating, mathematical modeling did not differ significantly, there is evidence that the two groups differed in their performance on conceptual understanding. It was shown that students learned algebra using graphing calculators view graphs more globally. The attitude survey assessed students' attitudes and perceptions about the value of mathematics, the usefulness of graphs in mathematics, mathematical confidence, mathematics anxiety, and their feelings about calculators. The overall t-test was not statistically significant, but the students in the treatment group showed significantly different levels of anxiety toward mathematics.

This paper introduces a search method based on conceptual graph. A hyperlink information is essential to construct conceptual graph in web. The information is very useful as it provides summary and further linkage to construct conceptual graph that has been provided by human. It also has a property which shows review, relation, hierarchy, generality, and visibility. Using this property, we extracted the keywords of web documents and made up of the conceptual graph among the keywords sampled from web pages. This paper extracts the keywords of web pages using anchor text one out of hyperlink information and makes hyperlink of web pages abstract as the link relation between keywords of each web page. 1 suggest this useful search method providing querying word extension or domain knowledge by conceptual graph of keywords. Domain knowledge was conceptualized knowledged as the conceptual graph. Then it is not listing web documents which is the defect of previous search system. And it gives the index of concept associating with querying word.

Students' participation in epistemic practices, which are related to knowledge construction on the part of students, is becoming a crucial part of learning (Goizueta, 2019). Research on epistemic practices in science education draws attention to teachers' support of students to engage in epistemic practices in mathematics instruction. The research highlights a need for incorporating epistemic goals, along with conceptual and social goals, into instruction to promote students' epistemic practices. In this paper, I investigate how teachers interact with students to integrate epistemic goals. I examined 24 interaction excerpts that I identified from six interview transcripts of two beginning teachers' mathematics instruction. Each excerpt was related to the teachers' talk about their specific interaction(s) in a small group. I explored how each teacher's discursive moves and goals were conceptual, social, and epistemic-related as they intervened in small groups. I found that both teachers used conceptual, social, and epistemic discursive move but their discursive moves were related only to social and social goals. This paper suggests supporting teachers to develop epistemic goals in mathematics instruction, particularly in relation to small groups.

The purpose of this study is to investigate how to teach algorithms in mathematics class. Until recently, traditional school mathematics was primarily treated as drill and practice or memorizing of algorithmic skills. In an attempt to shift the focus and energies of mathematics teachers toward problem solving, conceptual understanding and the development of number sense, the recent reform recommendations do-emphasize algorithmic skills, in particular, paper-pencil algorithms. But the development of algorithmic thinking provides the foundation for student's mathematical power and confidence in their ability to do mathematics. Hence, for learning algorithms meaningfully, they should be taught with problem solving and conceptual understanding.

본 연구는 수학 학습에서 긍정적이거나 부정적으로 발현되는 학습자의 감정이나 학습자가 보유한 수학에 대한 신념, 태도가 수학 학습 결과에 영향을 미친다는 연구에 기반하여 학습자 감정이나 정의적 요소들을 학습자 자신의 학습 목표나 목적에 맞게 조절할 수 있는 요소를 강구하고자 하였다. 이를 위하여 메타 정의에 관련된 연구들을 연결망 분석을 통하여 종합적으로 분석함으로써 메타 정의의 정의적 요소를 추출하고 이에 대한 개념을 분류, 그 의미를 탐색하였다. 그 결과 메타 정의의 정의적 요소로서 감정, 태도, 신념, 메타 정의의 개념 요소는 알아차리기(자각), 평가, 조절, 활용, 모니터링으로 도출할 수 있으며, 각 개념 요소에 대한 의미를 정의하였다. 본 연구 결과는 수학교육 분야에서 의미 있게 다뤄지는 정의적 영역과 관련하여 정의적 요소의 규명이나 특성에 대한 고찰을 넘어, 수학 학습에서 감정적 영역을 조절하고 이를 활용하기 위한 방안으로의 메타 정의의 개념 요소와 의미를 탐색하였다는데 그 의의가 있다.
