Problem posing activity of which a learner reinterprets an original problem via a new problem suggested, is a learning method which encourages an active participation and approves self-directed learning ability of the learner. Especially gifted students need to get used to a creative attitude to modify or reinterpret various mathematical materials found in everyday usual lives creatively in steady manner via such empirical experience beyond the question making level of the textbook. This paper verifies the possibility of lesson on question making strategy utilization for creativity development of gifted class, and analyzes various cases of students' trials to modify the rules of a board game called Rummikub in application of their own mathematics after learning What-If-Not strategy.

This study was planned to investigate the effects of mathematical games with motion on young children's development. The study was performed to compose mathematical games with motion and just mathematical games for young children. The games were set up to be executed 16 times for 8 weeks. The results of this study were as follows: Mathematical games with motion had a significant effect on young children's mathematical problem-solving ability. Mathematical games with motion had a significant effect in every category on young children's ability for motion competence and mathematical games with motion had a significant effect on young children's socio-emotional development. There were significant differences between the control group and the experimental group except for the independence from teachers and peer interaction. Mathematical games with motion had a significant effect on young children's language ability.

The purpose of this paper is to analyze a positive educational effect of G learning(online game based learning). G learning has become an effective learning tool for constructivism based learning. Therefore, the paper developed G learning 'SKY math' and applied it to the elementary students. Through the analysis, the fact has been found that students' attitude and confidence for Math changed positively.

게임에서 캐릭터가 점프 하는 중 플레이어가 스킬을 사용하면, 모든 물체가 정지 되는 기능을 구현해야 하는 상황에 놓이게 된다. Unity Engine에 내장 된 중력을 사용하면, 플레이어가 스킬을 사용 할 때 Rigid Body 속성을 사용하여 움직임을 제한할 수 있다. 그러나, 스킬 사용으로 인한 움직임정지를 해제 할 때 물체의 이전 속력이 사라져 움직임이 부자연스럽게 된다. 이를 해결하기 위해 수학 계산을 통해 시간 값에 따른 중력 값을 대입 하는 방법을 사용하면, 속력이 매우 커 타일을 통과해서 지나가는 현상이 나타난다. 본 논문에서는 다음 프레임 위치 계산을 통해 이러한 문제를 보정하는 방법과 수학 계산식을 통해 속력을 계산했을 때의 문제점 보완 방법 등에 대하여 연구하였다.

The computer game industry has been developed gradually because of development of graphics and communication industry, Games have an important role to peoples in various ages in their leisure life. Game has been changed into various forms with its development. With this movement, it is not only for simple amusement, but starts trying to use them for educational object. It is called Serious Game that intends to particular object and effect. Serious game has the important meaning to get some new useful things through its enjoyment which is the essence of games. Many people in various field have tried many categories of contents. Especially, education stands out among the other fields. Fields related with education have been studied extensively. This paper would suggest mathematics education game based on Augmented Reality. It is a board game for infants and young students. Augmented Reality is used to extend user's experience and multiplicity of the game. We also offer users a tool that helps them to create their own board for their active game participation.

This study is a study on the coding mathematics curriculum that converges elementary and middle school mathematics and information subjects and a minimum coding game-based education method for this. For the past 3 years, the coding mathematics curriculum and educational methods to effectively operate the curriculum were studied by applying them to 6th graders of elementary school and 1st graders of middle school. As a result of the first year of research, the coding mathematics curriculum was modified to a coding environment including the mathematical concept of a three-dimensional coordinate space, and the three-dimensional object was improved to be output as a real 3D print. As a result of the 2nd year study, it was improved so that even low-level students can build buildings by introducing different level commands for each component of the building so that self-directed learning is possible. As a result of the 3rd year study, a teaching-learning strategy based on a minimal coding game was designed to induce an increase in the level of computational thinking, and evaluation and feedback for diagnosing computational thinking were developed. Educational methods to promote self-directed learning and computing thinking ability, and researched coding mathematics curriculum are meaningful for the research and practice of the convergence education of school mathematics and informatics.

지능형 게임 개발을 위하여 게임 이론의 정의, 게임의 구성요소, 전략적 게임의 분석을 통해 게임에 대한 배경 환경을 살펴보고, 보다 사실적 느낌 전달을 위한 게임 애니메이션과 게임에 적용되는 인공지능 기술을 퍼지 이론, 뉴럴네트웍으로 분류하여 적용 현황을 살펴보았다. 즉 게임처럼 수학적 표현이 어려운 경우 해결점을 퍼지 이론에서, 캐릭터의 움직임을 제어하는 퍼지 Rule Base를 찾아내는 연구를 신경망 인공지능을 통해 해결하는 과정을 살펴보고 국부해의 단점을 갖는 신경망 인공지능의 불투명성 해결 방법을 유전자 알고리즘에서 찾았다. 결론적으로 게임에서 이루어지는 물리적 특성인 충돌에 대한 충돌검사 알고리즘, 충돌반응에 대한 최적화를 유전자 알고리즘을 적용하여 해결하였다.

We performed the research and education programs using engineering tools such as Mathematica, Microsoft Excel and GeoGebra for the students in mathematics mentorship program of the institute of science education for the gifted. We used the engineering tools to solve the problems and found the rules by observing the solutions. Then we generalized the rules to theorems by proving the rules. Mathematica, the professional mathematical computation program, was used to calculate and find the length of the repeating portion of the repeating decimal. Microsoft Excel, the spreadsheet software, was used to investigate the Beatty sequences. Also GeoGebra, the dynamic geometric software, was used to investigate the Voronoi diagram and develop the Voronoi game. Using GeoGebra, we designed the Voronoi game plate for the game. In this program, using engineering tools improved the mathematical creativity and the logical thinking of the gifted students in mathematics mentorship program.

This article tried to review the meaning and implication of six stages theory of learning mathematics suggested by Zoltan Dienes in "Building up Mathematics" in 1971. It was not much concretely known to Korean mathematics education society. In particular, there is no mathematical example which could cover all the stages to know what the theory tells. So this article focused on the example which Dienes developed for learning integers in 2000 to dig the theory. As a result, some critical aspects and problems of six stages theory were found. And finally educational implication was described.
