The purpose of this study is to develop a board game design activity for environmental education and to investigate how it affects high school students' environmental knowledge, environmental literacy, and creative engineering problem solving propensity. Twenty-five freshman and sophomore students belonging to the environmental club participated in this study. The board game activity was designed as 10 class hours lessons based on the engineering design process. The main data source of this study was pre-post students' conceptual maps of the environmental topics (global warming or ecosystem destruction) to measure the background knowledge on the topic. In addition, the environmental literacy measurement questionnaire and the creative engineering problem solving propensity questionnaire were collected before and after the activity. The result shows that the number of environment-related words described by the students on the post-concept map increased compared to the pre-concept map. In addition, the environmental literacy score and the creative engineering problem-solving propensity score increased significantly after performing the board game design activity. The results show that environmental lessons using board game design activities can help student develop various competencies in a good way. As above, research that combines board games and secondary education must be activated, and a new educational method and systemic support for in-service teachers who want to apply it to science classroom is required.

강원도 춘천시에 위치한 소양호는 북한강 상류수계로서 1973년에 준공된 우리나라 최대의 인공호이다. 소양호는 준공 이후 주변 유역의 인구밀집도가 낮고 오염물질 유입원이 적어 빈영양호의 수질을 보였다. 준공 후 소양호 수질에 영향을 미친 주요 환경요인으로는 1980-90년대 가두리 양식, 1990년대 후반부터 현재까지 지속되는 문제는 상류에서 강우시 발생된 탁수유입이 있다. 이러한 환경 문제로, 소양호에서는 식물플랑크톤 일차생산력, 동물플랑크톤 및 식물플랑크톤 장기변동, 용존산소 일주기 변동, 호수 내 유기물 분포 등의 연구가 이루어져 왔다. 그러나 가두리 양식장의 철거로 한 가지 요인은 해결되었으나 상류 탁수 유입 문제는 현재까지 진행 중이다. 소양호에서는 매해 여름철 탁수 유입이 지속적으로 발생하고 있으며 부영양화를 초래할 수 있는 주요한 문제이다. 이에 본 연구는 소양호에서의 장기적인 생태계 변동성 연구를 위해 1982년부터 현재까지 월 1-4회 수질 모니터링을 실시 중이며, 수질항목은 SS(Suspended Solids), TN(Total Nitrogen), TP(Total Phosphorus), BOD(Biochemical Oxygen Demands), TOC(Total Organic Carbon), Chl-a(Chlorophyll-a)에 대해 분석을 진행하고 있다. 기존 연구에서는 주-월 단위로 모니터링을 실시하여 강우에 의한 탁수 유입, 타 오염원에 의한 오염물질 및 유기물 유입으로 인한 실시간 수질 변동을 파악할 수 없었으며, 이벤트 발생 이후의 경과만 관찰할 수 있는 한계점이 있었다. 그러나 앞으로의 진행될 연구는 고빈도 센서를 이용하여 실시간 짧은 간격으로 모니터링하여 소양호 수질의 일주기 변동 분석과 오염원 유입과 같은 이벤트 발생 전·후 비교 및 실시간 수질변동에 대해 연구하는 것이며, 기존 데이터와 함께 진행될 연구의 데이터를 활용하게 된다면 소양호에서의 장기적인 수질 변화를 분석하는 데 효과적일 것으로 예상된다.

This study was carried out in order to identify the error types of statistical graphs for statistical literacy education. We analyze the meaning of using graphs in statistical problem solving, and identify categories, frequencies, and contexts as the components of statistical graphs. Error types of representing categories and frequencies make statistics consumers see incorrect distributions of data by subjective point of view of statistics producers and visual illusion. Error types of providing contexts hinder the interpretation of statistical information by concealing or twisting the contexts of data. Moreover, the findings show that tasks provide standardized frame already for drawing graphs in order to avoid errors and pay attention to the process of drawing the graph rather than statistical literacy for analyzing data. We suggest some implications about statistical literacy education, ethical problems, and knowledge for teaching to be considered when teaching the statistical graph in elementary mathematics classes.

This study is an attempt to analyze the information problem and the informational education in information society through the two cultural paradigms of ‘system‘ and ‘life world’, which are used to interpret the social problems in modern age. Information problem concerns the individual problems such as reference and validity problem of information and social problems like paradox of information, information technology, and equal opportunity. From the discussion was deduced the fact that the informational education is the cultural media to arbitrate the conflict between the reasonable solution of the individual information problem in ‘life world’ and the control attempt by ‘system’ to cope with the social information problem. It is also indicated that the aim of the informational education is the information autonomy which can be built through the information literacy.

The purpose of this study was to develop a test tool for convergence problem solving skill. To this end, constructs of convergence problem solving skill were defined in three domains: convergence attributes, convergence thinking, and convergence literacy domains. Thirty-seven pilot items were developed on the basis of the sub-categories for each domain that was defined through intensive literature review; problem solving & convergent thinking and creative thinking for convergence thinking domain, individual and social propensity for the convergence attributes domain, and convergence literacy as convergence literacy domain. Through an exploratory factor analysis, 30 items in the constructs of the test tool were confirmed. A confirmatory factor analysis result showed that the five construct models well captured the covariance between all the items well. Finally a statistical result shows that the reliability of the items and constructs were well established (Cronbach's α value= .963). Thus, the test tool for convergence problem solving skill developed in this study was statistically reliable.

The purpose of this paper is to propose the policy change of teachers education in Korea with an analysis of America statistical literacy education. we found the difference of statistical literacy education between Korea and America with each nation's social and educational environment. We can get the need of new change for statistic teacher's education in Korea. We think of Mathematics teachers should know about the difference between statistics and mathematics at school mathematics. And they should know the new change thinking about teaching method and process assesment methods. Second, Teachers should focused on teaching of problem solving and statistical thinking ability based on data analysis than the teaching of probability and mathematical theory.

To grow as talents with future oriented knowledge and creativity, students need imaginative power and creativeness, and to that end, mathematics and science subjects may help. Students need activities that help gain explorative mind for new things, concentrating ability, researching ability and creativeness, and such attributes can be improved through the activities of making various shapes utilizing space geometry in 4D-frame. Such activities not only contribute to defining ability in mathematics but also cherish the qualifications required as architects and space scientists.

This study investigated middle and high school students' perceptions of scientific literacy in the $21^{st}$ century through the survey. Subjects were 952 students from 13 participating schools. 482 middle school students and 470 high school students, 471 male students and 481 female were involved. The survey questionnaire asked which elements they thought would be important to be scientifically literate in the $21^{st}$ century and why they chose the elements. The results showed that most of the students tended to focus on orientation, content knowledge, and mindset. A large portion of female students showed orientation was the most important element. On the other hand, male students showed that scientific knowledge as well as orientation was important.

디자인은 일반적으로 목적지향의 창의적인 문제해결 과정으로 볼 수 있으며, 그 결과로 구체적인 대상이 세상에 존재하게 되는 것이다. 즉 무형적인 컨셉트를 가시적인 대상으로 전환시키는 산업 디자인분야에서 시각심상의 표현을 통한 조형성과 창의성은 디자이너의 중요한 소양중의 하나가 된다. (중략)
