The purpose of this study was to examine the relationship between teacher's role and interaction patterns in mathematics classrooms. Teacher's role was divided into usual practices with students, usual practices with content and usual practices with students and contents, and interaction patterns were classified into report, inquiry and discussion. The subjects in this study were teachers and students in three fourth- grade classes in T elementary school located in Seoul. After the classes of every math teacher were observed, three teachers who played distinctively unique roles were selected in accordance with the results of the first-semester autonomous supervision, of open class for parents and of the instructional observation. Thus, there was a close relationship between the teacher roles and interaction patterns. And it's concluded that students are able to have a more discussion on each other's ideas in the student-centered classroom, and that teachers should perform active roles in that process. Given the findings of the study, there are some suggestions: First, the teachers appeared to fulfill consistent roles when their videotaped classes, study aids and performance assessment materials were analyzed, and they should play more active roles in mathematics class. Second, they should try to create the kinds of climate that encourages students to come up with ideas in an active manner. Third, earlier studies had focused on student-teacher interaction patterns, but this study found that the roles of the teachers depended on interaction with not only students but study aids and performance assessment materials, and that the interaction patterns hinged on their roles as well. Therefore more profound research efforts should be directed into this issue.

The purpose of the research is to assure the effect of learner-centered instruction driven from the constructivism. The school in participation of the research is one of them called "achievement increase intensive school". Quasi-experimental design is applied for the research. Some conclusions were drawn from the research. Experimental group' achievements of both "learned contents" and "none learned contents" were more superior than ones gained from comparative group with statistically significant difference. The results implied that learner-centered instruction is effective for students who have low achievements from standards tests.

수학 학습에서 컴퓨터와 계산기의 활용은 시각화의 강화로부터 직관력과 사고력의 향상을 가져왔다. 컴퓨터 대수체계(Computer Algebra System)가 탑재된 수학 학습용 컴퓨터 프로그램과 계산기가 활발히 사용되고 있으며, 교수매체로서의 활용은 지식 정보전달 체계와 학습자의 지식 구성방법에 새로운 패러다임을 형성하였다. 특히 수학학습용 그래픽 계산기(Graphing Calculator)는 휴대형(Hand-held Technology)으로 학습공간의 이동(Mobil Education)이 가능하며, 수학학습 전용기라는데 의미를 둘 수 있다. Symbolic Graphing Calculator를 활용한 수업에서 학습자는 계산기를 가지고, 기호연산 실행 조작을 통해 자신의 사고과정을 표현하고, Symbolic Graphing Calculator는 실행 조작에 즉각적으로 과정과 결과를 제공하며, 다른 표상과 상호작용을 함으로써 학습자 스스로의 규제가 강화된 과정을 통해 지식을 구성하게 된다. 이때 교사는 지식 정보전달 체계인 대화형 실행매체(IMTs)를 작성하여 학습자의 지식 형성에 안내자의 역할을 하게 된다. 이번 워크샵에서는 CASIO fx 2.0을 활용한 교실 수업모형을 그래프 표상과 연계한 방정식의 풀이과정을 통해 알아본다.

The purpose of this study was to understand the structures underlying Korean elementary teachers' attitudinal beliefs toward reform-oriented mathematics instruction and predict their intentions to change traditionally-oriented teaching practice. The theory of planned behavior (TPB) developed by Fishbein and Ajzen provided a conceptual framework for the examination of factors that influence Korean teachers' beliefs, attitudes, subjective norms and perceptions of control factors. Data were gathered through a survey instrument from 281 teachers who teach mathematics in a metropolitan city of Korea. Descriptive statistics and multiple regression analyses were conducted to analyze the data. Findings indicate that Korean elementary teachers' change in Instructional practice is based primarily on their judgements regarding the likelihood of occurrences of certain consequences if they engage in teaching mathematics in a reform-oriented way. Teachers' perceptions of important others regarding the reform-oriented mathematics instruction seem to play a minor role in teachers' instructional change. Teachers' perceptions about control factors that prohibit or help teach mathematics in a reform-oriented way do not seem to make significant improvement in predicting their intentions to change traditionally-oriented teaching practice.

The 7th national curriculum requires the paradigmatic shift in education from teacher-centered to student-centered instruction. But, teachers beliefs on instruction have not been changed during implementing of the mathematics textbooks based on the curriculum. More exactly speaking, they are changed very slowly. Therefore, some beliefs they should establish in order for them to implement it were discussed: Perspectives of students' intelligent ability, learning goal for the every lesson, the passibility of teaching contents involved in the national curriculum, the size of classroom, and students' achievements.

The 7th national curriculum shifts the fundamental spirit from teachercentered to learner-centered instruction. According to the shift, performance assessment has been emphasized in schools rather than using a variety of standardized tests. However, some researchers and educational policy-makers recently asserted that we need to return to the kind of standardized tests used in the past, giving up performance assessment, for it can actually not be implemented in classroom. This paper is written to refute their assertion. Performance assessment prove one's real worth when it is implemented in learner-centered instruction. Therefore, some assessment methods are discussed which can be used during learner-centered instruction.

Learners who have taken learner-centered instruction is expected to construct conceptually mathematical knowledge which is. If so, they can have some ability to solve problems they are confronted with in the first time. To know this, First graders who have been in learner-centered instruction during 1 school year was given 7+52+186 which usually appears in the national curriculum for 3rd grade. According to the results, most of them have constructed the logic necessary to solve the given problem to them, and actually solve it. From this, it can be concluded that first, even though learners are 1st graders they can construct mathematical knowledge abstractly, second, they can apply it to the new problem, and third consequently they can got a good score in a achievement test.

본 연구의 목적은 예비 초등교사의 수학 수업에 대한 자기효능감을 조사함으로써 예비 교사를 위한 수학 교육프로그램 개선에 도움이 되고자 하는데 있다. 기존의 문헌 분석에 의하면 수업에 대한 교사들의 자기효능감은 수업 수행 능력과 학생들의 학습에 크게 영향을 미치는 것으로 알려졌다. 뿐만 아니라 최근 우리가 지향하고 있는 교사들에 대한 학습자 중심 수학 수업으로의 개선과 변화된 수업 방식의 지속성에 매우 유효한 요인이 된다. 예비 초등교사들을 대상으로 한 본 연구 결과에 의하면 이들의 수학 수업에 대한 자기효능감은 보통의 수준에 머물러 있으며, 특히 상당수의 예비 교사들은 자신의 수학 수업에 대한 자신감이 매우 부족한 것으로 들어났다. 이러한 결과는 아마도 현재 교육대학교에서 예비 교사들에게 제공하는 수학 교육과 관련된 과목을 수강할 수 있는 기회가 매우 제한적인 데서 그 원인을 찾을 수 있으며, 이는 또한 수학 교육 프로그램의 초점이 예비 교사들의 수학 수업 능력의 측면에 초점이 맞추어져야 한다는 것을 시사한다. 예비 교사들의 수학 수업에 대한 자기 효능감은 그들이 이해하고 있는 수학 교수법적 지식과 매우 관련이 깊은 것으로 나타났다.

The 7th curriculum sets a basic direction based on learner centered teaching. To this end, the curriculum puts a focus on activity centered classes using teaching tools. In reality, however, elementary school teachers find using the teaching tools in their classes difficult, although there are various studies going on to improve the practical use of the teaching tools in the classroom. In this paper, we present an effective approach to utilize those prior studies on using the teaching tools in classes for 4th, 5th and 6th graders.

Problem-Based Learning has many implications on teaching and learning. Through the problem-Based Learning, students device their plans to solve the given problems and discuss with workers to find and share some ideas or mathematical contents needed to solve those problems. In this paper we studied characteristics of Problem-Based Learning problem and tried o find out the standard criterion of problem analysis that were appropriate to Problem-Based Learning. We applied them to analyze problems in textbooks and problems that were developed for Problem-Based Learning. Using he result, the further research questions and implications were suggested.
