This paper aims to develop a program which cultivates statistical ability for elementary students. For this purpose, I examined the relationship between mathematical thinking and statistical thinking. I developed statistical programs including classification, discussion of data, generating statistical problem and project program. As result, this study suggests implications for further elementary statistical education.

Statistics was not recognized until the early 20th century as an independent science, and statistical education research came to an international milestone in the late 1940s. The purpose of this study is to investigate the historical development of statistics education research, focusing on the activities of the International Statistical Institute (ISI) and the International Association for Statistical Education (IASE). Statistics education in Korea is considered with regard to the history of international research on statistics education in this study. It implies for the direction of statistical education research to domestic mathematics education researchers and statistical researchers related to statistical education research.

통계는 삶의 문제에서 출발하여 주어진 문제를 해결하기 위해 통계문제로 번안되고, 자료가 정의되고 수집되어 적절하게 통계를 활용하여 원문제의 해결을 해야 한다. 그러므로 통계교육은 이러한 연장선상에서 유기적이고 체계적으로 이루어져야 한다. 이 논문에서는 초등 통계 영역이 가지는 문제점들로 교육과정상의 문제점, 교과서 구성 측면에서의 문제점, 수업 운영의 문제점, 실생활과의 연계 부족, 다른 영역과의 연계성의 문제, 통계에 대한 인식의 문제 등을 살펴보았다. 이러한 문제점의 해결방안에 대해 탐구하여 초등통계교육의 개선을 위한 시사점을 제공하는데 그 목적이 있다.

This study aims to investigate the statistical literacy of pre-service mathematics teachers and to discuss the impact of statistical literacy in lesson plan. For the purpose of this study, we analyzed 13 pre-service mathematics teachers' statistical literacy tests and lesson plans. The results of this analysis are as follows: First, pre-service mathematics teachers did not have a high level of statistical literacy, and it was also observed that there was a big level difference between them. Second, pre-service mathematics teachers' lesson plans showed significant difference in the level of the target grade, the characteristics of the target student, and the contents. Based on this study, we seek to find implications for how it is appropriate to educate teachers in charge of statistical education.

The purpose of this study is to analyze whether statistics and statistical education of intensive courses at the teachers college can improve elementary pre-service teacher' statistical attitudes. Findings on this study are as follows: First, there was meaningful difference in the elementary pre-service teacher' attitudes with significant level of 0.05. This proved that statistics and statistical education of intensive courses at the teachers college was effective on improving elementary pre-service teacher' attitudes. Second, there was meaningful difference in the pre-service math teacher' conception in the 2009 reformed curriculum for elementary mathematics.

최근 통계적 소양, 추론, 사고에 중점을 둔 통계 교육의 필요성이 강력하게 제기되었다. 특히 통계 교육의 목적으로서 통계적 소양의 중요성이 주목을 받고 논의되고 있다. 이에 따라 선행연구를 중심으로 통계적 소양에 대해 고찰하고자 한다. 그동안 논의되었던 통계적 소양의 정의, 구성요소를 살펴본다. 그리고 학교 수학교육과정에서 통계교육의 목적을 살펴보고, 통계적 소양의 측면에서 우리나라의 통계 교육을 위한 시사점을 생각해 본다.

Taking samples of data and using samples to make inferences about unknown populations are at the core of statistical investigations. So, an understanding of the nature of sample as statistical thinking is involved in the area of statistical literacy, since the process of a statistical investigation can turn out to be totally useless if we don't appreciate the part sampling plays. However, the conception of sampling is a scheme of interrelated ideas entailing many statistical notions such as repeatability, representativeness, randomness, variability, and distribution. This complexity makes many people, teachers as well as students, reason about statistical inference relying on their incorrect intuitions without understanding sample comprehensively. Some research investigated how the concept of a sample is understood by not only students but also teachers or preservice teachers, but we want to identify preservice secondary mathematics teachers' understanding of sample as the statistical literacy by a qualitative analysis. We designed four items which asked preservice teachers to write their understanding for sampling tasks including representativeness and variability. Then, we categorized the similar responses and compared these categories with Watson's statistical literacy hierarchy. As a result, many preservice teachers turned out to be lie in the low level of statistical literacy as they ignore contexts and critical thinking, expecially about sampling variability rather than sample representativeness. Moreover, the experience of taking statistics courses in university did not seem to make a contribution to development of their statistical literacy. These findings should be considered when design preservice teacher education program to promote statistics education.

초등학교 수학에서 자료와 가능성 영역은 통계적 과정에서 요구되는 기초적인 통계적 내용을 학습하여 통계의 기초 소양을 기르는 단원이다. 학생들은 실제 자료에서 정보를 추출하고, 이를 표와 그래프로 정리하여 결론을 통계적으로 추론하며, 합리적인 의사결정을 내리는 과정을 경험한다. 본 연구에서는 '그림그래프에서 추론하기' 과제에 대한 초등학교 5, 6학년 학생들의 통계적 소양을 분석하여 초등학교에서 추론 학습 가능성과 통계적 소양의 관점에서 그림그래프의 교육적 가치를 살펴본다. 학생들의 통계적 사고를 길러주는 것은 통계교육에서 중요한 목표이며, 비형식적인 통계 추론의 경험은 이후 학습할 형식적 통계적 추론에 도움을 줄 수 있다. 따라서 '그림그래프에서 추론하기' 과제에서 나타나는 초등학생들의 통계적 소양에 대한 논의는 학교 통계 교육에 유의미한 시사점을 제시할 것이다.

There are many statistical information sites as the use of internet is increased quickly in recent years. In this paper, we explore and analyze internet sites for statistical information such as statistical survey system, education, database, and terminology. And then we classify these sites to apply statistical information to some particular spheres easily. In so doing, this study result aims at enhancing our understanding of internet sites for statistical information.

These days, with the emphasis on statistical literacy, the importance of communication is the focus of attention. Communication about statistics is important since it is a way of describing the understanding of concepts and the interpretation of data. However, students usually have trouble with expressing what they understand, especially through writing. In this paper, we examined preservice teachers' difficulties when they wrote about statistical concepts. By comparing preservice teachers' written responses and interview transcripts of the variance concept task, we could find the missing information in their written language compared to their verbal language. From the results, we found that preservice teachers had difficulty in connecting terms contextually and conceptually, presenting various factors of the concepts that they considered, and presenting the problem solving strategies that they used.
