Elementary information education is currently provided in accordance with the 2000 ICT educational guidelines. Although the focus of education has shifted from practical use to computer science since 2005, in which way academic education should be led isn't yet clear. The purpose of this study was to examine the impacts of computer science education(CS education) by an education programming tool on school children's awareness of that education. The selected students received education about unplugged, scratch and robot programming, part of the computer science curriculum, in 12 sessions. As a result, there were significant differences between the experimental and control groups in all the variables that included attitude to computer science, interest in that, satisfaction level, self-efficacy and perception of the value of CS education. The findings of the study suggested that in CS education, the improvement of thinking faculty should take precedence over practical use of what's learned, which is expected to heighten the value of that education.

Developing computational thinking ability is crucial for those living in the 21st century. However, the current computational education system cannot satisfy this need. Current computational education tends to be limited to the teaching of the use of application programs or the teaching of the programming language. This is why the primary puzzle-based learning program was developed. This program promotes the development of the learner's computational thinking ability and understanding of the principles of the computer science as opposed to the fragmented, uniform programing education. In order to prove the effectiveness of this newly developed program, a 35-hour study was conducted to 41 students from grade 3 to 6 classrooms in Jeju Province. It was proved that this program brings positive changes in creativie problem-solving ability and problem-solving abilities in computer science. This paper is to provide the ground for the development of an educational program and to prove the effectiveness of thereof, and finally introduce the Primary Puzzle-Based Learning Program as the alternative computational education.

This method is a new experimental model for a mathematical education in Engineering students. We compare two different classes; one was recorded the lecture with scenario and the other was not. Also we set up the detailed structures in every lecture for mathematical modeling and solving parts. The purpose for a new model is 1) to improve the students's ability to solve the mathematical problem, 2) how to approach to getting a solution for each problem by system and 3) to provide the lectures anytime to students who want to study more mathematics.

In this study we present a new approach for computing the partial atomic charge derived from the wavefunctions of molecules. This charge, which we call the "y_charge", was calculated by taking into account the energy level and orbital populations in each molecular orbital (MO). The charge calculations were performed in the software, which was developed by us, developed using the C# programming language. Partial atomic charges cannot be calculated directly from quantum mechanics. According to a partitioning function, the electron density of constituent molecular atoms depends on the electrostatic attraction field of the nucleus. Taking into account the Boltzmann population of each MO as a function of its energy and temperature we obtain a formula of partial charges.

A minimum terminal path decomposition of a tree is defined as a partition of the tree into edge-disjoint terminal-to-terminal paths that minimizes the weight of the longest path. In this paper, we present an $O({\mid}V{\mid}^2$time algorithm to find a minimum terminal path decomposition of trees. The algorithm reduces the given optimization problem to the binary search using the corresponding decision problem, the problem to decide whether the cost of a minimum terminal path decomposition is at most l. This decision problem is solved by dynamic programing in a single traversal of the tree.

In this research, Integrated program base on heat transfer & numerical analysis was developed. Also, reaction of gifted student and possibility of application of this program was surveyed. This program consist in three parts. The first part is computer programing language, the second part is numerical modeling of physical phenomena, and the third part is numerical analysis. 4 students are selected who belong to mathematic class of CNUE(Cheoungju National Univ. of Edu.)'s Gifted Student Education Center. The Program consists in 15th lessens, and each lessen need 4hr. Application possibility and student's satisfaction of the program are studied through the interview and report of the student. Three of four students are accomplish the goal of the progarm. Computer programing and numerical analysis parts were relatively well understood, but numerical modeling part was difficult to students. The satisfaction of the program is dependent on the characteristics of the student. Most of the student thought that this program was one of the science education program. The student who have interested in only mathematics shows that low satisfaction but the one who have interested in science or information technology shows that high satisfaction.

Digital Game design with educational purposes and User Experience measurement via game analytics has been extensively covered in literature, however non-digital games such as tabletops in education and its corresponding educational impact have limited research. In this paper, we propose a guideline to create non-digital educational games from scratch and evaluate them based on the know-how of developers and the investigation of scholars who have studied the engagement factors related to the digital games and applied their findings to non-digital games. Along with the guideline we provide an actual implementation, a game called HXGN_766, meant to serve as scaffolding of computational thinking and rudimentary Python programing concepts. We believe both, guideline and game, can be a useful reference for those interested on game design, educational content design, game quality control check, and unplugged computer science activities. This is the first in a series of papers where the game design concept, the evaluation methodology and the game itself will be presented with more detail.

Our society is endemic in safety insensitivity, yet we have been concerned for safety education and disaster drill since the Sewol Ferry accident. However, the practical training costs very high, and it has its limit to increase reality. Recently, industry fields put emphasis on virtual reality (VR) as alternatives, so various contents are invented by using advantages of VR. The paper explores crucial application in 3-dimensional simulation for fire drill, suggests novel design, and contemplates about educative result through designing process. In order to construct and materialize the suggested system, practical 3D spatial information model and various disaster-drill scenarios are necessary. Also, to apply game elements for augmentation in users' utility, educations based on computer science and visual art are inevitable, which requires skills in programing and modeling respectively. Thus, this study investigates educational effect of convergence field through the suggested system designing process.
