This study identifies elements involved in designing rehearsals for improving preservice teachers' capacity to teach mathematics. Observation of a secondary mathematics methods course and regular interviews with the teacher educator following each class were used in this research. After characterizing what is considered and enacted in rehearsals as a way to help preservice teachers practice the work of teaching mathematics, I illustrate them with examples from the observations and interviews. I then discuss the challenge of dual contexts-the teacher education classroom and the secondary mathematics classroom-and dual perspectives-the mathematical and pedagogical-in designing and enacting rehearsals. I conclude with implications for mathematics teacher education.

본 연구는 5, 6학년 수학 교사용 지도서의 도전 수학에 나타난 수학적 사고의 유형을 분석하여 교육적 시사점을 논하기 위하여 수행되었다. 이를 위하여 교수·학습 내용을 바탕으로 평가 및 육성이 가능한 수학적 사고의 유형을 정리하고, 수학적 사고를 분석하기 위한 틀을 구상한 뒤, 초등학교 5, 6학년 수학 교사용 지도서의 '도전 수학'에 나타나는 수학적 사고를 분석하였다. 분석 결과, 첫째, 우리나라 초등학교 5, 6학년 수학 교사용 지도서의 '도전 수학'은 계획 수립, 실행의 단계에서는 다양한 수학적 사고를 지도할 수 있는 여러 가지 유형의 문제로 구성이 되어있다. 다만 자세한 보조문항으로 인하여 의도된 수학적 사고만이 발현될 것이 우려되며, 스스로 수학적 사고를 유발할 수 있는지는 불분명한 경우가 많았다. 둘째, 교사용 지도서의 문제 이해 단계와 반성 단계의 발문이 매우 전형적으로 제시됨으로써 해당 단계에서는 다양한 수학적 사고를 유발하기 어렵다. 셋째, 교사용 지도서에는 수학적 사고에 대한 명시적 설명이 부족하며 추후 개발될 교사용 지도서에서는 수학적 사고에 대한 명시적 설명을 보완해 주는 것이 필요할 것이다.

The mathematics education community is seeking to change a teacher-centered class-room culture to a student-centered culture. However, the real transition is not easy, even for teachers who are eager and willing to teach differently. The challenge for teachers is to use the social structure of the classrooms to nurture students' development toward mathematical ways of thinking and communicating as well as their under-standing of mathematical concepts and processes. By introducing an elementary teacher's teaching practice and professional develop-ment along with her classroom episodes, this paper is to make strides toward an enriched understanding of the culture of the elementary mathematics classrooms in which students may have a lot of opportunities to develop conceptual under standing and math-ematical disposition. This paper first provides a detailed description of the classroom flow in terms of general social norms and sociomathematical norms in order to explore how the teacher and the students have established such a student-centered math-ematics microculture. This paper then analyzes the teacher's teaching approach and professional development.

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.

This study was conducted to examine the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness. The sample included 308 early childhood education major students, and the data were collected using the Modified Orientation to Teach Survey (MOTS), Teaching-belief type scale, and self-directed learning readiness scale. A statistical analysis included correlation analysis and stepwise multiple regression analysis. The results were as follows: 1) analysis of the relationship between pre-service early childhood teacher's motivations of choosing a teaching profession, educational belief, and self-directed learning readiness conveys that intellectual stimulation and self-directed learning had the strongest relationships while nature of work had the weakest. For educational belief and self-directed learning readiness, maturationism and interactionism showed significantly positive correlations while behaviorism displayed a negative correlation. Behaviorism had a significantly negative correlation with openness for challenge, a sub-factor of self-directed learning. 2) Analysis of the effect of pre-service early childhood teacher's motivations of choosing a teaching profession and educational belief on self-directed learning readiness indicates that pre-service early childhood teacher's motivations of choosing a teaching profession had a stronger effect on self-directed learning. These results suggest the following: successful performance as an early childhood teacher not only requires receiving institutionalized education but also self-directed learning while working as an early childhood teacher.

학습자 중심 교육과정을 기본정신으로 하는 제7차 수학과 교육과정이 실시되고 있지만, 여전히 일선 현장에서 실천되고 있는 수업은 전통적인 교사중심 수업의 아류에 지나지 않는다. 다시 말해서 전통적인 수업에 익숙하던 교사가 학습자 중심 수업을 충실하게 실천한다는 것은 대단한 도전이다. 본 논문은 전통적인 수업을 하던 교사가 학습자 중심 수업을 실천하면서 자신이 형성하고 있던 아동관, 교과서관, 교사관 등에서 새로운 인식의 변화를 진술하고 있다.

It is noted that although the current state of development of web-based English education (hereafter referred to as WBEE) might not meet the criteria some educators have set for themselves in the field, students certainly seem to prefer studying in a web-based and computer-assisted learning environment. This kind of demand is fueling the drive to develop more suitable variations of WBEE. In order for WBEE to work out, a teacher should be a multifunctional type of instructor handling responsibilities such as the role of scriptwriter to create text, act as technician for the sound mixing and recording, preside over online chat rooms and discussion boards, and finally, as webmaster to maintain the site and supervise all academic/ clerical work related to the course. Therefore, it is suggested that WBEE be accompanied by a small personnel to divide the labor and lessen the burden on the actual teacher. Finally, it is noted that the traditional relationship between students and teacher may no longer be sustainable since WBEE does not provide the face-to-face style of class discussion and office hours in its current form. Until the technology is fully developed to compensate for these kinds of differences, it is an immediate challenge to provide other more compelling reasons for students to participate in WBEE.
