본 연구의 목적은 예비 지구과학교사들이 학생에 의해 구성된 기후변화 모델을 평가하는 기준을 탐색하는 것이다. 대도시 소재 대학 지구과학교육과 전공 수업에서 3주간 모델링 기반 과학 학습에 대한 강의를 수강한 예비 지구과학교사 25명이 연구에 참여하였다. 예비 지구과학교사들이 작성한 고등학생들이 구성한 7개의 기후변화 모델을 평가하는 보고서와 사후 인터뷰 자료를 수집하여 기후변화 모델 평가 기준을 귀납적으로 범주화하였다. 연구 결과 예비 지구과학교사들이 기후변화 모델을 평가할 때 다양한 인식론적 기준과 의사소통 기준을 동원하였음을 확인하였다. 연구 결과를 바탕으로 모델링 기반 기후변화 학습에 대한 시사점을 도출하였다.

본 연구에서는 예비 초등 교사들을 대상으로 천문현상(계절 변화와 달의 위상변화)에 대한 정신모형과 그 모형에 영향을 주는 요소들을 조사하였다. 본 연구에 참여한 예비교사는 교육대학교에 재학 중인 학생이다. 자료 수집은 지필 검사와 개별 면담을 통해 이루어졌다. 연구 결과, 예비 초등 교사들은 천문현상의 설명들이 과학적 모형과는 다른 합성 정신모형들을 가지고 있었으며, '거리 이론' 과 '가리기 이론'이 그들의 정신 모형에 가장 큰 영향을 미치는 것으로 나타났다. 또한 예비 초등 교사들이 갖는 천문현상의 합성 정신모형의 구조와 근원을 알아보기 위하여 그들의 정신 모형들을 형성하는 틀 이론과 특정 이론을 집중적으로 탐색하였다. 끝으로 연구 결과와 관련된 예비 교사교육에의 시사점을 논하였다.

This study investigated relationship between preservice kindergarten teachers' cognitive strategies and self-determination motivation types. Cognitive strategies were measured by 3 variables surface, deep, and metacognitive strategies; motivation for self-determination was measured by 7 variables; intrinsic motivation(IM) to know, IM to accomplish, IM to experience stimulation, external regulation, introjected regulation, identified regulation, and amotivation. The Motivated Strategies for Learning Questionnaire(Pintirch & DeGroot, 1990) and the Academic Motivation Scale(Vallerand et al., 1992, 1993) were administered to 82 subjects. Data were analyzed by Pearson's correlation, multiple regression analysis, and canonical correlation analysis. Finding were a positive correlation between IM to know and IM to accomplish. IM to accomplish positively predicted surface, deep, and metacognitive strategies, and identified regulation positively predicted deep cognitive strategy. Amotivation negatively predicted deep and metacognitive strategies.

What constitutes a good mathematics lesson plan? In their teacher education program, preservice teachers (PSTs) are trained for planning mathematics instruction but often have difficulty in evaluating existing lesson plans and creating their own lesson plans. The purpose of this narrative inquiry is to understand PSTs' experiences of evaluating or designing mathematics lessons that they perceive as being good. The narratives of three PSTs who pursue high school mathematics teaching certification will inform us not only of their perceptions of a good mathematics lesson and lesson plan but also their process of finding the one that exists or creating their own.

This study investigated three preservice 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 preservice 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.

초등학교에서 교사는 그들이 가르쳐야 하는 수학에 관한 지식 뿐 아니라 그들의 학생들이 미래에 배워야하는 수학에 관한 지식도 풍부하여야 한다. 초등수학의 수와 연산 영역 중에서 초등학교 학생들이 매우 어려워하는 개념 중 하나가 나눗셈 개념이다. 이에 본 연구는 우리나라 초등예비교사 178명을 대상으로, 그들이 실제 교사로서 교육현장에 나서기 바로 이전 시기에 나눗셈 개념에 있어서 적절하게 개념적 지식과 절차적 지식을 관련지어 이해하고 있는지, 나눗셈에서 나누는 수와 나머지와의 관계에 대해 올바르게 이해하고 있는지 등에 관해 알아봄으로써 그들의 수학적 지식의 이해 정도를 살펴보았다. 그 결과, 대부분의 초등예비교사들이 나눗셈에 있어 개념간의 관련성과 단위에 대한 이해가 충분하지 않은 것으로 나타났다.

This study is to understand preservice science teachers' previous experience, beliefs about teaching and learning, and visions of themselves as future teachers. The data were collected from two individual interviews with 7 voluntary students and analyzed qualitatively for category construction. As the results of this study, we presented two cases, which showed that their different views of teaching science are strongly related to their previous experiences as learners and observers in schools, and that there is the apparent consistency between each participant's beliefs about science teaching and learning and their own visions of teaching in a science classroom. Implications for preservice science teacher education related to the results were discussed.

The enhancement of the quality of the teaching practice is a major factor in securing better schooling opportunities for students. In this article, initial teacher preparation of secondary school Earth science teachers, in-service science teacher education, and improving teacher policy are discussed. Data from in-depth interviews with exemplary science teachers were used to explore how to improve the quality of science teacher education in Korea. In terms of preservice teacher education, most exemplary teachers contended that teacher education programs should provide preservice teachers with practical knowledge by translating theory into practice. Their suggestions for how to improve in-service education are also discussed. Regarding directions of improving teacher policy in Korea, the teachers proposed an alternative teacher-promotion structure that incorporates the master-teacher position. Implications for introducing action research courses into teacher (re)education programs are also discussed.

This study sought to examine preservice teachers' beliefs about their intent to use computers and Internet resources in mathematics classrooms. Also, web-based instruction on topics in elementary school mathematics was used to foster teachers' confidence and competence in using instructional technology, thereby promoting positive attitudes toward use of computers and Internet resources in the mathematics classroom. The results indicated that students who participated in the web-based instructions exhibited a significantly (p < 0.05) better attitude toward using computers and web-based resources in teaching mathematics than did students in the control group.

A case study was conducted to investigate the understandings of the subject matter knowledge and pedagogical content knowledge held by 63 elementary preservice teachers in dealing with the division by a fraction. The study results showed that, in terms of the subject matter knowledge, the preservice teachers did not have a conceptual understanding of the division by a fraction and, in terms of the pedagogical content knowledge, they depended heavily on algorithms without a conceptual understanding of the meaning of the division by a fraction.
