This study explored the heterogeneous latent group on the influence of the learner's perceived math teaching method(instructor-centered, learner-centered) on math self-efficacy. In order to profile the characteristics of the detected latent group, the distribution of variables was confirmed, and multi-group analysis was conducted by SEM. According to the analysis results, two latent groups were detected, and the instructor-type group and the learner-type group were named. As a result of post-hoc analysis, the perception of instructor-centered classes and learner-centered classes, and the perception of math teaching ability were similar between the instructor-type and the learner-type group. But the instructor-type group had higher math self-efficacy, math interest, and math class engagement than the learner-type group. Also, in the instructor-type group, the effect of perception of math teaching ability on math self-efficacy and math class engagement was greater than that of the learner-type group. Whereas, in the learner-type group, the effect of math interest on math self-efficacy and math class engagement was greater than that of the instructor-type group. This study presented a new research method on the influence of math teaching methods on learners by applying the REBUS-PLS method.

The purposes of this study were to explore in depth about 5th graders' mathematical speaking and writing abilities and to investigate differences on those abilities. The study involved three-5th graders and their speaking and writing abilities in geometry area were analyzed. According to the results of the study. the children had difficulties in selecting and using appropriate mathematical languages to explain mathematical concepts, mathematical ideas, and problem solving steps. The children who participated in the study showed higher ability in speaking than writing.

This study investigated three pre-service teachers' mathematical problem solving among hand-in-write-ups and final projects for each subject. All participants' activities and computer explorations were observed and video taped. If it was possible, an open-ended individual interview was performed before, during, and after each exploration. The method of data collection was observation, interviewing, field notes, students' written assignments, computer works, and audio and videotapes of pre- service teachers' mathematical problem solving activities. At the beginning of the mathematical problem solving activities, all participants did not have strong procedural and conceptual knowledge of the graph, making a model by using data, and general concept of a sine function, but they built strong procedural and conceptual knowledge and connected them appropriately through mathematical problem solving activities by using the computer technology.

The purpose of this study is to scrutinize the characteristics of a teacher's discursive competence on the basis of mathematical competencies. For this purpose, we observed all semester-long classes of a middle school teacher, who changed her own teaching methods for the last 20 years, collected video clips on them, and analyzed classroom discourse. Data analysis shows that in problem solving competency, she helped students focus on mathematically important components for problem understanding, and in reasoning competency, there was a discursive competence which articulated thinking processes for understanding the needs of mathematical justification. And in creativity and confluence competency, there was a discursive competence which developed class discussions by sharing peers' problem solving methods and encouraging students to apply alternative problem solving methods, whereas in communication competency, there was a discursive competency which explored mathematical relationships through the need for multiple mathematical representations and discussions about their differences. These results can provide concrete directions to developing curricula for future teacher education by suggesting ideas about how to combine practices with PCK needed for mathematics teaching.

The purpose of this study is to analyze the discourse structure of teachers that can help students participate in class by using mathematical metaphors that can arouse students' interest and motivation. In order to achieve this goal, we observed a semester class of a career teacher who practiced pedagogy that connects students' experiences with mathematical concepts to motivate students to learn and promote participation. Among the metaphors that the study target teachers used in a variety of mathematical concepts and problem-solving processes during the semester, we extracted the two class examples that can help develop teaching methods using metaphors. Representatively selected two classes are one class example using metaphors and, the other class example using metaphors and expanding and applying problems. As a result of analysis, the structure of teacher discourse that uses metaphors and expands and applies problems by linking students' experiences with mathematical content was found to help solve a given problem and elaborate mathematical concepts. As a result of the analysis, the discourse structure of teachers using mathematical metaphors based on communication with students could provide implications for the development of teaching methods for the recovery of mathematics education.

본 연구는 초등학교 수학에 적용 가능한 수학사를 추출하고 이를 효과적으로 활용할 수 있는 수업 모형을 개발하여, 수학사를 활용하는 수업이 학생들의 수학적 의사소통과 수학적 태도에 어떠한 영향을 미치는지 알아보았다. 이를 위해 실험집단에는 수학사를 활용한 수업을, 비교집단에는 교과서를 활용한 강의식 수업을 실시하였으며, 연구 중에 수집된 자료는 양적 분석과 질적 분석 방법을 병행하여 분석하였다. 그 결과 첫째, 수학사를 활용한 수학수업은 학생들의 의사소통 참여도를 향상시키는 데에 도움을 주었으며, 둘째, 학생들이 수학적 논리를 가지고 자신의 의견을 상대방에게 정당화하게 하였다. 또한 셋째, 수학사를 활용한 수학 수업이 학생들의 수학적 태도를 긍정적으로 변화시키는 데에 효과가 있음을 알 수 있었다.

본 논문은 학생중심 수학교실문화를 구현하려고 노력하는 3명의 초등학교 교사들이 공동으로 1년간의 프로젝트에 참여하면서 경험하게 되는 교수법 개발 과정에 관한 사례를 소개한다. 이를 바탕으로, 수학 교사 학습 및 교수법 개발에 있어서의 성공과 난제가 무엇인지 살펴보고, 본 프로젝트에서 새롭게 적용해 본 교사 중심의 정기적인 수업 논의 모임을 통한 탐구 공동체 형성과정과 이를 통한 교사 학습에 관한 쟁점을 논의한다.

본 연구는 중학교 1학년 함수 학습을 위해 패턴 활동으로 구성된 함수 지도 프로그램을 개발하고, 개발한 프로그램을 적용한 실험 집단(85명)과 교과서를 적용한 비교 집단(85명)간의 함수 학습에서의 효과를 분석하였다. 함수 지도 프로그램은 학생들이 패턴 활동을 동해 함수적 사고를 기르며, 활동적으로 수업에 참여하여 수학에 대한 자신감과 실생활의 연계성을 가질 수 있도록 구성하였으며, 적용 결과, 수학 수준별 수업을 하는 상반에서는 유의미한 차이를 보였고, 중반에서는 유의미한 차이는 없었으나 수업 시간에 흥미가 매우 높았다는 긍정적 평가를 할 수 있다.

The purpose of this research is to seek for principles and methods of multicultural mathematics teacher education. It began with an overview of theories of multicultural education and of multicultural teacher education in order to address the questions of what is the goal of multicultural education and what constitutes the competence of multicultural teachers. Then, cases of multicultural mathematics teacher education were reviewed. Based on that, this research identified three domains of teacher competence: domains of affect, of cognition, and of behavior. This paper also presented what constitutes each domains of competence and how to promote the development of each type of teachers' multicultural competence. This paper discussed implications to multicultural teacher education in Korean society.

대부분의 수학 수업이 알고리즘을 숙달시키고, 기계적으로 익힌 절차에 의해 정답을 맞추는 것에 중점을 두어 왔기 때문에, 학생들은 수학은 딱딱하고 어렵고 재미없는 과목이라는 인식을 많이 하고 있다. 그러나, 수학 수업에서 수학 교구의 조작 활동을 한다면 수학적인 흥미를 유발할 수 있을 뿐만 아니라 추상과 형식적인 수학으로의 발달을 돕고 학생들이 활동적으로 수업에 참여할 수 있게 된다. 이러한 맥락에서 제 7차 교육과정의 '도형'영역에서는 조작 활동을 통한 자기 학습능력 개발에 중점을 두고 주위의 실제 생활에서 볼 수 있는 사물을 관찰하여 그 성질을 추상해 낼 수 있도록 구체적인 교구를 이용하는 조작 활동을 강조하고 있다. 본 연구에서는 이러한 관점에서 정규 수학 수업이 아닌 일선학교의 클럽 활동 시간을 이용하여 학생들이 수학 교구를 충분히 조작하고 활용할 시간을 제공하며, 학생들이 수학 교구의 조작 활동을 통한 클럽활동이 학생들의 수학적 성향 및 능력 수준에 따른 도형 학습능력에 어떠한 변화를 미치는 지를 사례를 중심으로 논의하고자 한다.
