This paper proposes elementary robot programming problems using the algorithmic thinking-based problem model with material factors in the elementary robot programming. And this paper proves the validity of developed robot programming problems in defining them as algorithmic thinking-based problems through experiments. The experimental results are analyzed in views of variety and effectiveness evaluation of answer algorithms and suitability of allocating degrees of difficulties to the developed robot programming problems. As a result of the experiment, we find that the developed problems has various answer algorithms and suitable degrees of difficulties for elementary school students.

This study is aimed at providing the theoretical framework of characteristics of mathematical thinking processes and structuring the thinking process patterns of the mathematical gifted students through the analysis of their cognitive thinking processes. For this purpose, this study is trying to analyze characteristics of mathematical thinking processes of the mathematical gifted students in an objective and a systematic way, by using think-aloud method. For comparative study, the analysis framework with the use of the thinking characteristic code as a content-oriented method and the problem-solving processes code as a process-oriented method was developed, and the differences of thinking characteristics between the two groups chosen by the coding system which represented the subjects' thinking processes in the form of the language protocol through thinking-aloud method were compared and analyzed.

Computer applications for engineering design evolve rapidly. Many design frameworks were developed by the simulation based systems so that organizations could achieve significant benefits due to cost reduction in designing. However, today’s transient design issue requires being adaptable to more complicated and atypical problems. In this paper the Multidisciplinary Language Runtime (MLR) design framework is developed. The MLR provides flexible and extensible interface between analysis modules and numerical analysis codes. It also supports Meta Modeling, Meta Variable, and XML script for atypical design formulation. By applying object-oriented design scheme to implement abstractions of the key components required for iterative systems analyses, the MLR provides flexible and extensible problem-solving environment.

The paper provides an efficient method for generating water crown animation. Compared to general liquid simulation, water crown animation requires tremendous computational loads. Tackling the problem, we propose a novel geometry based approach with procedural texture. Unreal engine is utilized to construct material and handle the geometric mesh combined with water texture. The experimental results demonstrate our method achieves effective performance for realistic water crown animation.

영재교육진흥법과 그 시행령이 발표된 이래 2003년 현재 초등의 경우 91개의 영재교육원과 101개의 영재학급에서 전체 학생의 약 0.22%가 교육을 받고 있으며, 점차 그 대상이 확대 운영될 예정이다. 영재교육을 실시함에 있어서 우선적으로 해결할 문제는 '어떤 사람이 영재이며, 영재를 어떻게 판별할 것인가?' 그리고 '그들에게는 어떤 교수 ${\cdot}$ 학습 프로그램을 제공할 것인가?'이다. 그러나, 현재 영재에 대한완전한 정의가 내려지지 못했으므로 표준화 될 수 있는 판별 모델도 없다. 본 연구에서는 영재 판별에 관한 문헌 연구 및 현재 실시중인 영재교육원 중 몇 곳의 영재 선발 과정 비교 ${\cdot}$ 분석을 통하여 우리 실정에서 실현 가능한 영재 판별 방법 및 절차에 관한 모델, 판별 시 고려사항 등을 알아본다.

Companies are attempting application of open source software development approach method as new alternatives to solve roiling pints of the existing software developments such as quality of software, development speeds and cost. On the other hand, various analyses about open source software were performed, but concrete procedures or the results of suitable study about a way to utilize open source for a software development in actual industry are not yet. This study presented process model for identification, valuation selection of suitable open source, and modification application or commercializing.

As the contents of information were reinforced the rules of computer science, it was necessary to develop the new teaching and learning plans and various education materials that encourage students and easy to access. So, in this study developed a wide ran of play activities and educational materials without using a computer for the area of information representation and applied to 68 students, second grade of middle school for 4 weeks. After the class, the effect on the learning achievement was verified by the t-test. As a result, it was shown that there was a significant difference between learning with play activities materials and the traditional lecture-type. It means that learning with play activities materials in the information representation influences a positive effect to the learning achievement.

Data collection is crucial to the process of statistical problem solving since it influences the quality of statistical data. However, there is little instruction on data collection in the Korean mathematics curriculum. In this study, we examined how the data were collected and how the data collection method was taught in the Korean mathematics textbooks for 3rd and 4th grades. As a result, the data appeared in these textbooks were collected by using a variety of methods, including surveys, experiments, observations, and secondary data collections. There were not enough instructions on experiments and observations, compared to surveys and secondary data collection. Additionally, as each textbook works with a distinct contents while teaching data collection, it is expected that there would be variations in the levels that students learn in relation to data collection. Based on these findings, we draw some discussion points to determine how to improve the mathematics curriculum in order to effectively teach data collection in the elementary school.

최근의 개정된 7차교육과정의 '정보' 교과에서는 기존의 컴퓨터활용위주 교육대신에 컴퓨터과학과 문제해결능력을 강조하는 내용으로 개편되었다. 이 교육 과정은 2010년 중학교 1학년부터 적용하여 2013년 고등학교 3학년까지 단계적으로 적용할 계획에 있다. 이에 본 연구에서는 개정된 '정보' 교육과정의 내용에 관련 있는 '초 중등학교 정보통신기술 교육 운영지침'의 내용을 중등학생이 어느 정도 파악하고 있으며, 4단계의 영역('정보사회의 생활', '정보기기의 이해', '정보처리의 이해', '정보가공과 공유')과 '종합 활동'의 학습 내용간에 인지도의 차이를 분석한다. 이 분석 결과를 바탕으로 현재 일선학교에서 시행되고 있는 '초 중등학교 정보통신기술 교육 운영지침'의 운영상의 문제점을 학생인지도 측면에서 지적하고 이의 개선점을 제시하고자 한다.
