학생들의 수업 중 몰입에 영향을 미칠 수 있는 요인으로는 학습자의 흥미, 교사의 칭찬 등 여러 가지가 있을 수 있으나 가장 중요한 요인은 학습자의 사고를 존중하고 가치롭게 여기는 교사의 태도 및 교실 분위기이다. 학습자의 사고를 존중하고 가치롭게 여진 수 있는 교실 풍토는 수업 내내 이루어져야 하는 것이지 수업의 동기 유발 측면에서 수업 도입부에 일시적으로 행해지는 수업 행위가 아니다 이를 이끌어 낼 수 있는 요인들 중에서도 본 고에서는 아동관, 수업자료, 교사의 발문에 대한 논의를 하였다. 이 모든 논의의 중심에는 학습자 중심 수업의 기본 전제인 '학습자는 스스로 지식을 구성할 수 있는 능력을 소유한 인격체'란 점이 반영되어 있다.

본 연구는 고등학교 진학을 위한 입시라는 독특한 수학 교실 배경이 있는 중국 중학교 수학 교실에서 일어나는 교실 담화를 분석하는데 목적이 있다. 이를 위하여 본 연구에서는 수학 교실 담화를 시작 발화로서 교사 발문 통계와 교사 발문 유형별 에피소드를 분석하였고, 교실 담화 구조 분석으로는 특히 다섯 가지 IRF 하위 유형을 밝혀낼 수 있었다. 중국 귀주성 귀양시에 위치한 H학교에 재직 중인 세 명의 수학 교사가 녹화했던 수학 수업 총 15개의 녹취록과 교사 서면 인터뷰 내용을 중심으로 자료를 분석하였다. 본 연구 결과를 보면, 차시별로 평균 20개 교사 발문이 관찰되었고 교사 발문의 사회적 스케폴딩 역할이 있었으며, 교사 발문 유형은 확인형 발문(이해확인 발문, 설명요구 발문, 상세요구 발문, 재확인 발문)과 정보형 발문(정보제시 발문)으로 분류되었다. 그리고 교실 담화 분석에 따르면 IR형 담화 구조는 거의 관찰되지 않았으며, IRF형 담화 구조의 경우는 단편적인 평가, 평가 및 이유, 근거 설명, 평가 및 학생 반응 재진술, 다른 사고나 해법 안내, 그리고 학생 답 수정이나 교사 의견 제시로 구분되었다.

The purpose of this study was to examine the effect of the manipulative materials in the Australian Maths 300 program by applying it to Korean Elementary Mathematics Education - based on parts of 'Probability and Statistics', and 'Symbol and Expression'. In order to this purpose, we select appropriate Maths 300's manipulate materials that could be used to obtain learning objectives within class time for each part, four lessons with the materials were taught at to third, fourth, and fifth grade students of elementary School. The effect of the teaching was analyzed by videotape and student opinion. The results of this study are the following: First, the manipulative tools were almost entirely lacking for the 'Probability and Statistics' section without a 'number of cases' unit. The tools presented in the 'Symbol and Expression' section were helpful in the games that were used for checking preceding learning. Second, the results of using the Math 300 manipulative materials in class showed that the students were eager to be involved in the activities using those materials and to find their own solutions in problem-solving questions that were suited to them; these led to them making their own questions. In response to questioning about the use of the manipulative materials, the students stated that it was easy and fun for them to use the manipulative materials, to solve the problems for themselves, and that they would like to continue practicing the activities in the future. Finally, Studies on the presentation of a variety of manipulative materials including those in this study that can used in problem-solving learning and other learning fields, and the methodology for the use of manipulative materials can be enhanced through further studies.

본 연구는 영재학급에서 수업 중 교사가 강조하는 지도 목표와 학생들이 인식하는 학습 목표 도달 정도의 차이를 분석해 봄으로써 영재학급에서의 학습 목표 제시 방식을 개선하는 데 목적이 있다. 이를 위해 초등학교 6학년 2개 학급(각 20명씩 총 40명) 학생들의 활동지를 양적으로 분석하였으며, 각 학급 내 성취 수준이 상, 중, 하위권에서 각 1명씩을 대상으로 수업 중 연구자 참여 관찰과 수업 후 개별 면담을 통해 그들의 학습 목표 인식 사례를 질적으로 분석하였다. 학습 목표는 내용면, 과정면, 태도면에서 각각의 하위 요소별로 교사가 사전에 기술해 놓은 것에 대해 교사 자신이 강조한 정도와 학생이 인식한 정도의 간극을 항목별로 차이를 수치화하여 비교하였다. 연구 결과 영재학급 학생들은 내용면보다는 상대적으로 과정면에서 학습 목표에 대한 인식이 낮음을 알 수 있었는데, 전반적으로 연역적 사고, 유추적 사고, 발전적 사고에 있어서 교사의 강조 정도와 인식 정도의 차이를 보였고 특히 유추적 사고에서 학습 목표에 대한 그 인식 정도가 가장 큰 차이를 보였다. 이를 통해 얻게 된 몇 가지 교육적 시사점을 제시하였다.

This paper explores students' question generation process and their study in small group discussion. The research is based on Anthropological Theory of the Didactic developed by Chevallard. He argues that the savior (knowledge) we are dealing with at school is based on a paradigm that we prevail over whether we 'learn' or 'study' socially. In other words, we haven't provided students with autonomous research and learning opportunities under 'the dominant paradigm of visiting works'. As an alternative, he suggests that we should move on to a new didactic paradigm for 'questioning the world a question', and proposes the Study and Research Courses (SRC) as its pedagogical structure. This study explores the SRC structure of small group activities in solving ill-structured problems. In order to explore the SRC structure generated in the small group discussion, one middle school teacher and 7 middle school students participated in this study. The students were divided into two groups with 4 students and 3 students. The teacher conducted the lesson with ill-structured problems provided by researchers. We collected students' presentation materials and classroom video records, and then analyzed based on SRC structure. As a result, we have identified that students were able to focus on the valuable information they needed to explore. We found that the nature of the questions generated by students focused on details more than the whole of the problem. In the SRC course, we also found pattern of a small group discussion. In other words, they generated questions relatively personally, but sought answer cooperatively. This study identified the possibility of SRC as a tool to provide a holistic learning mode of small group discussions in small class, which bring about future mathematics classrooms. This study is meaningful to investigate how students develop their own mathematical inquiry process through self-directed learning, learner-specific curriculum are emphasized and the paradigm shift is required.

This paper presents cross-national perspectives on challenges in implementing current mathematics education reform ideals. This paper includes detailed qualitative descriptions of mathematics instruction from unevenly successful second-grade classrooms both in Koran and in the U. S with regared to reform recommendations. Despits dramatic differences in mathematics achivement between Korean and the U.S student. problems in both countries with regard to mathematics education are perceived to be very similar. The shared problems have a common origin in teacher-centered instruction. Educational leaders in both countries have persistently attempted to change the teacher-centered pedagogy to a student-centered approach. Many teachers report familiarity with and adherence to reform ideas, but their actual classroom teaching practices do not reflect the full implications of the reform ideals. Given the challenges in implementing reform, this study explored the breakdown that may occur between teachers adoption of reform objectives and their successful incorporation of reform ideals by comparing and contrasting two reform-oriented classrooms in both countries. This comparison and contrast provided a unique opportunity to reflect on possible subtle but crucial issues with regard to reform implementation. Thus, this study departed from past international comparisons in which the common objective has been to compare general social norma of typical mathematics classes across countries. This study was and exploratory, qualitative, comparative case study using grounded theory methodology based on constant comparative analysis for which the primary data sources were classroom video recordings and transcripts. The Korean portion of this study was conducted by the team of four researchers, including the author. The U.S portion of this study and a brief joint analysis were conducted by the author. This study compared and contrasted the classroom general social norms and sociomathematical norms of two Korean and two U.S second-grade teachers who aspired to implement reform. The two classrooms in each country were chosen because of their unequal success in activating the reform recommendation. Four mathematics lessons were videotaped from Korean classes, whereas fourteen lessons were videotaped from the U.S. classes. Intensive interviews were conducted with each teacher. The two classes within each country established similar participation patterns but very different sociomathematical norms. In both classes open-ended questioning, collaborative group work, and students own problem solving constituted the primary modes of classroom participation. However in one class mathematical significance was constituted as using standard algorithm with accuracy, whereas the other established a focus on providing reasonable and convincing arguments. Given these different mathematical foci, the students in the latter class had more opportunities to develop conceptual understanding than their counterparts. The similarities and differences to between the two teaching practices within each country clearly show that students learning opportunities do not arise social norms of a classroom community. Instead, they are closely related to its sociomathematical norms. Thus this study suggests that reform efforts highlight the importance of sociomathematical norms that established in the classroom microculture. This study also provides a more caution for the Korean reform movement than for its U.S. counterpart.
