The purpose of this study is to find the correlation between the level of 6th graders' achievement level in Probability and Statistics education, which were proposed in the curriculum, which targeted the 6th graders in the elementary school, and statistical literacy. For this, first, questions asking the achievement level in the probability and statistics(Part A), and questions asking the statistical literacy(Part B), were used to study the achievement level of the students. Second, the achievement level in the probability and statistics, and the statistical literacy were measured. In order to achieve the purpose of this study, questionnaire that consists of 10 questions was invented. The questionnaire was divided into Part 1 and Part 2 under the consideration upon the characteristics of the questions. The results of the questionnaires given to the students were classified into "high, medium, and low" and were separated into 7 categories. Results of comparing category 3 and category 6, which have shown opposing tendencies, we could find that students who are good at school mathematics and students with high statistical literacy have respective and different characteristics. For actually effective statistical education, consideration upon and reflection of core aspects such as intuition and critical thinking in the curriculum are needed.

Water in Soyang River is an essential source for citizens of Chuncheon and Seoul areas. In 2006, turbid water in Soyang River aggravated by the typhoon Ewiniar, sustained for over 280 days unlike conventional years, then which interrupted water supply of Chuncheon and Seoul areas. Soil erosion derived from high cool lands constituting about 55% of Soyang River area is considered one of main causes for the turbid water, including imprudent development of mountainous area, road expansion, and road construction for forestry. According to analysis of turbidity, precipitation and reservoir level in Soyang River region for June 2006${\sim}$August 2008, the turbidity showed a peak correlation (r = 0.28) at a lag time of 49 days and especially did an excellent correlation (r = 0.60) with the reservoir level at a lag of 4 days. In the meantime, a critical turbidity of 31 NTU at Soyanggang Dam was estimated, over which would cause turbid water at Paldang Dam. In addition, a master recession curve was suggested, from which sustaining time of turbid water can be predicted.

Curriculum can represent the identity of University as an important factor, and especially university has sole power to design and manage his curriculum. So, the information literacy curriculum which teach students to create, store, communicate their knowledge is very important position in the liberal arts curriculum. Thus, this study designs the reference model as 3-dimensional cubic model for information literacy curriculum to help curriculum designers design, manage, and evaluate it. For developing this model, I researched many books and web sites about some of domestic and U.S. universities' curriculums, and made up some questionnaires about students' satisfaction and the direction of information literacy education. An information literacy curriculum was designed using this reference model and lots of students are satisfied with this curriculum after activating in this class. Designed cubic reference model which has a characteristic to expose flexible and systematic context representation in the university curriculum can guide researchers to design, manage, and evaluate information literacy curriculum.

This study analyzes how statistical literacy is implemented along with the statistical problem-solving process as described in the Statistical Estimation Unit of the textbook by the 2015 revised mathematics curriculum. The analytical framework was developed from the literature, and consists of 'context', 'variability', 'mathematical and statistical knowledge', 'using of technological instruments', 'critical attitude', and 'communication'. From the perspective of the statistical problem-solving process, the analysis revealed that many tasks equivalent to 'Analyzing Data' but lacked tasks related to 'Interpreting Results' and 'Formulating Questions'. As a result of analyzing the reflection of each element of statistical literacy, 'mathematical and statistical knowledge' was the most common task, but 'critical attitude' and 'using of technological instruments' were rarely dealt with. Based on the results of this textbook analysis, it was intended to provide implications for improving the curriculum and the development of textbooks for the growth of statistical literacy.

In Korea, the software education in elementary and middle school is essential to the 2015 revised curriculum, and various software education policies are being implemented. It is necessary to analyze the effects of these changes on computer and information literacy of students. This study investigates and analyzes the present state of computer and information literacy education in 32 middle schools nationwide. For the 640 students, we surveyed the students' status of coding education, confidence in computational thinking based on coding experience, confidence in computational thinking according to the frequency of computer use for learning purposes, and confidence in computational thinking ability according to the frequency of major ICT activities in class. As a result, there was a lack of Computer and Information literacy educational opportunities through school and relatively lack of educational opportunities for students in the rural area. And the more learning experience showed a positive impact on the confidence in computational thinking.
