학교 수학에서 확률 통계 영역은 자료에서 필요한 정보를 추출하고, 이 정보를 바탕으로 통계적 과정을 통해 타당한 결론을 추론하며 합리적인 의사 결정을 내리는 방법을 학습하는 단원이다. 통계 단원은 연역적 사고를 강조하는 학교 수학의 다른 영역과 달리 교실 수업의 과정에서 실제 자료를 통한 귀납적 추론과 올바른 직관적 사고를 필요로 한다. 따라서 통계 단원의 교수 학습 과정에서 교사들은 학생들에게 실제 자료에 대한 귀납적 추론과 직관적 사고를 바탕으로 하여 정보를 추출하고 타당한 결론을 추론하는 방법을 지도할 수 있어야 한다. 이에 따라 앞으로 일선에서 통계 교육을 담당할 예비 교사들도 통계 교육이 요구하는 통계적 추론 능력을 구성하는 것이 필요하다. 이에 본 연구에서는 예비 교사들이 구성하고 있는 통계적 추론 능력에 대하여 구체적으로 탐색해 보고자 하였다. 이를 위해 첫째, 선행 연구의 검토를 통해 학교 수학에서 요구하는 통계적 추론에 대해서 알아보고, 둘째, 예비 교사를 대상으로 한 통계적 추론 검사를 실시하여 그들의 통계적 추론 능력을 살펴보았다. 그리고 셋째, 예비 교사들의 반응을 토대로 그들이 구성한 통계적 추론 능력에 대한 분석과 함께 오개념을 구체적으로 탐색해 보고, 넷째, 통계 교육에서 예비 교사 교육을 위한 시사점을 제시하였다.

The objective of this study was to follow up changes in knowledge related to the mathematics education field work of preliminary early childhood teachers. The subjects of this research were 28 students who were taking mathematics education courses in early childhood education departments at various universities. This research ran for 15 weeks and was conducted through field work relating to mathematics education. The study collected data from pre-service teachers' knowledge, the diagram of concept, writing journals, interviews, and materials from the internet. Through this procedure, pre-service teachers' knowledge for mathematics education could later be expanded, ordered, and integrated. In addition, pre-service teachers not only understood the importance of contents and levels of lesson plans, but also learned how to utilize educational media to make effective lessons. Furthermore, pre-service teachers realized that the mathematical concepts of students could be expanded depending on the contents and methods of pre-service teachers' lesson plans and students could then apply these concepts into daily situations.

본 연구의 목적은 수학교육적 가치에 대한 예비 초등교사와 현직 초등교사의 인식을 확인하고 비교하는데 있다. 이를 위해 설문지를 활용하여 자료를 수집하고 주성분 분석(PCA)을 실시하여 요인 6개를 도출하였다. 이 요인은 체계적인 라벨링 과정을 거쳐 6가지 수학교육적 가치 즉 '재미', '문제 해결', '표현', '계산', '능력', '설명'으로 명명되었다. 예비 초등교사와 현직 초등교사 모두 '문제 해결'을 가장 중요하게 생각하였으며 이 요인에 대해 통계적으로 집단 간 유의미한 차이는 없었다. '설명'을 제외한 모든 수학교육적 가치에 대해 1학년 예비 초등교사, 4학년 예비 초등교사, 현직 초등교사 순으로 더 중요하게 여기는 경향이 있었다. 특히 예비 초등교사와 현직 초등교사 사이에 각 가치에 대한 인식의 차이가 두드러지는 것으로 나타났다. 이와 같은 연구 결과를 토대로 교사 교육 프로그램에서 수학교육적 가치의 구현과 관련하여 더 중요하고 의미 있게 다뤄야 할 것이 무엇인지 논의의 필요성을 강조하였다.

This study investigated the visual-mental capability of pre-service and in-service mathematics teachers as well as academicians making a career change to mathematics teachers with regard to manipulations of two geometric shapes (from 2- to 3-dimensional). Moreover, it investigated whether there are differences between the visual-mental capability of these participant groups. Findings illustrate that most of the participants demonstrate an adequate visual capability relating to the task dealing with a cube. Conversely, very low percentage of participants manifested a visual-mental capability in a task requiring the identification of a solid resulting from rotation of a square page, whose diagonal serves as the rotation axis. The study indicates that learners' high visual view should be developed in order to enhance their visual-mental capability.

As the recent demand for human resources in science, technology, engineering, and mathematics (STEM), the development of professional STEM teacher is called worldwide. It is becoming a critical need in teacher education in order to educate student teachers, and prepare pre-service and beginning teachers for high quality of teaching competency. To promote the competency for $21^{st}$ century STEM teachers, the epistemology of technological pedagogical content knowledge (TPACK) is currently considered as the essential qualities of knowledge for highly qualified teachers. The aim of this study is explore the effect of case-based learning approach on TPACK competency of pre-service STEM teachers. In order to develop the pre-service teachers' competency regarding effective integration of technologies into teaching specific content areas, a series of innovative case study teaching in science and mathematics was presented to 43 participants of pre-service physics, chemistry, biology, mathematics, and computer teachers during a course of information and communication technology (ICT) in Education at Khon Kaen University, Thailand. After finishing a case presentation, the pre-service teachers were encouraged into a forum of critical open discussion by considering the potential impact of the case and the TPACK framework. They were investigated instructional design competency of using ICT tools into student learning process and their personal beliefs about ICT in educational process both before and after. The participant's reactions and learning was evaluated by using a self-reported questionnaire and an implementation log of content-specific learning process design, respectively. Results showed a change of their beliefs and the transformation of their TPACK competency in STEM teaching. In an effort to better serve the needs of high quality STEM teachers, the results of this study illustrated that the competency of TPACK could be particularly considered as a core attributes for future STEM teachers. By the way, case-based learning approach can play an effective part in preparing and professing the TPACK competency for STEM teachers.

The purpose of this study was to investigate the nature of pre-service elementary teachers' metaphors on mathematics textbooks. Their metaphors describe individual and collective patterns of thinking and action on mathematics teaching and learning. To analyze their metaphors, qualitative analysis method based on Lakoff and Johnson's theory of metaphor (1980) was adopted. Metaphors on mathematics textbooks were elicited from 161 pre-service elementary school teachers through writing prompts. The writing prompt responses revealed three types and thirteen categories: As Type I, there were (1) 'Principles', (2) 'Summary', (3) 'Manual', (4) 'Encyclopedia', (5) 'Code', (6) 'Guidelines', and (7) 'Example'. As TypeII, there were (9) 'Assistant', (10) 'Friend', (11) 'Scale', and (12) 'Ongoing'. As TypeIII, there was (13) 'Trap'. Among these categories, 'Guidelines', 'Assistant', and 'Ongoing' were the most frequently revealed. These results indicate that the relations of mathematics curriculum, textbooks, and classrooms are not a unilateral way but should communicate with each other.
