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.

The purpose of this study was to investigate characteristics of interaction in mentoring conversations and to examine how the interaction features change as mentor teachers have more mentoring experiences. Participants of this study were three mentor who have over 17 years' teaching experience and six beginning science teachers. For this study, one-to-one mentoring dialogue recordings and transcripts were collected and the dialogues were analyzed by utilizing an analytical framework of interaction. the result of analyzing characteristics of mentors' interaction shows that mentors used simple questions and support the most when they started mentoring conversation. the change of characteristics of mentor's interactions indicates three mentors tended to use more thought-provoking questions in the $2^{nd}$ year mentoring than in the $1^{st}$ year and as a result of it mentee's reflection and reflective practices were increased. Through mentors' interview, the mentors could have the opportunity to reflect their own mentoring and this means mentors' self reflection was provoked by means of the mentoring program.

In effort to help vitalize environmental education which is the most efficient way to preserve environment and solve environmental problems and also to provide necessary basic data, this research was conducted on the primary and secondary school teachers in Daegu for their awareness of the elements of environmental education, for their interests in environment and environmental issues, for their sensitivity on the seriousness of the environmental issues and for their knowledge of environmental vocabulary. Followings are the results: 1. 96% of the teachers supported the necessity of school education on environment, but only 51% went for adopting environment as an independent subject. 2. The majority of 57% said that they came to recognize environment and environmental issues 'through media such as TV and radio'. For the desirable form of environmental education, 64% supported 'field study or experience activity'. As for the undermining factors, the majority of 50% cited 'excessive focus of school education on college entrance' and 29% 'limitations of class hours'. 3. With regard to their interests in environment and environmental issues, they were between 3.43～4.08 point range out of 5 points. For their sensitivity about the seriousness of environment and environmental problems, the survey showed the range of 3.49～4.28 points out of 5 points. 4. There was no remarkable difference in the level of recognition between male and female teacher. But, according to disparity of age, teachers who are in their forties and fifties recognized better than teachers in twenties and thirties. Also, there was a striking difference among primary school, middle school, and high school teachers. High school teachers had the highest recognition level, while, middle school teachers had the lowest recognition level.

This study examines effects of small group cooperative learning on areas of mathematics such as number and calculation, figure, and measurement, and changes of attitude-interest in math in elementary schools. Seventy eight second graders from Jinhae City were divided into the experimental group and the control group. The experimental group was subdivided into small groups of four students who belonged in different levels of math performance. The subdivision was renewed whenever each area was covered. An examination paper which had been developed by Ministry of Education & Human Resources Development and Kyeongsangnamdo Office of Education was given to the subjects. Also, a questionnaire was developed and given to the participants. The results show that, in general, the small group cooperative learning had good effects on the students' ability to solve math problems and, in articular, greater effects on the ability of low-level students. It is revealed that the interaction between the students in small groups affected their attitudes toward and interest in mathematics in a positive way, but did not make perceivable changes in self-confidence of the young Learners.

The purpose of this study was to analyze the extendibility of division algorithm and Euclid algorithm for integers to algorithms for rational numbers based on word problems of fraction division. This study serviced to upgrade professional development of elementary and secondary mathematics teachers. In this paper, fractions were used as expressions of rational numbers, and they also represent rational numbers. According to discrete context and continuous context, and measurement division and partition division etc, divisibility was classified into two types; one is an abstract algebraic point of view and the other is a generalizing view which preserves division algorithms for integers. In the second view, we raised some contextual problems that can be used in school mathematics and then we discussed division algorithm, the greatest common divisor and the least common multiple, and Euclid algorithm for fractions.

Elementary schools and middle schools currently manage their student data by using the education administration system. One of its sub-systems called 'the academic affairs support system' is especially dedicated to handle school and academic affairs data. By allowing simple data search and statistical data calculations, it helps teachers easily integrate and manage education information resources. However, it is not easy for teachers to analyze the correlations among student data. In this paper, we showed by examples that a lot of meaningful information can be extracted by analyzing the relations among student data. Based on the results, we designed and implemented SIMS as a tool to provide teachers with such services. SIMS makes use of Association Rules for data correlation analyses. SIMS can be used in connection with the academic affairs support system, and is much easier to use than previously developed commercial products for similar services.

The goal of the education of Information Communication Ethics(ICE) is to improve the consciousness level of adolescents so that they themselves are able to judge between what's ethically right and wrong and, as a result, to take the right behavior. For this, we need to preferentially identify the primary factors in understanding and diagnosing the consciousness level of adolescents on the ICE. To solve this problem, in this paper, we identified four major indices that consist of the ICE consciousness through the meta analysis of the both domestic and international researches from the past 5 years in the related area and then, they are validated by experts. We also analyzed the factors in assessing the ICE consciousness level of adolescents by using the Delphi technique, which, during its analysis, even considers elements that are qualitative or cannot be objectified. Finally we deduced 22 ICE factors given the weight through the AHP of an expert group that consists of experienced teachers and professors in the related area.
