게임의 스토리텔링 관점에서 보면 사용자가 스토리 라인을 따라 게임을 진행하면 그 게임의 목표를 달성하는데 효과적이지만 오늘날 대부분의 게임들이 사용자의 상호작용을 높게 허용하므로 초기 기획되었던 대로 스토리라인을 따라 진행되기가 어려운 경우가 많다. 이런 게임 환경에서 특별히 교육용 게임은 초기에 의도하였던 학습 목표를 달성하는데 어려움이 있다. 본 논문은 교육용 게임에 미니게임을 삽입한 경우의 스토리텔링 구조를 살펴보고 아동용 게임 속에 포함된 미니게임이 학습 목표 달성에 어떤 역할을 하는지 사례를 통해 분석하였다. 또한 효과적인 학습목표 달성을 위해 미니게임의 활용 방안을 제안하였다.

With the deployment of web-based educational game over the internet, the user's registration becomes a critical element. The user is authenticated by the system using username, password, and unique code. However, it cannot be handled properly because the data is transmitted through insecure channel on the network. Hence, security requirement is needed to avoid identity leakage from malicious user. In this paper, we propose a secure communication approach using SSL protocol for an online game. We also describe the security requirements for our approach. In future work, we intend to configure and implement the SSL protocol by enabling HTTPS in web-based online game.

This study investigated how presence will affect the user's trust in educational serious game. To achieve our research purposes, we divide presence into two parts: virtual presence and social presence and identify the relationship between trust and trustworthiness. and also, we separate out trust such as trust in learning and trust in fun according to users purposes. We conduct the survey using the english serious game for university student. The results show that presence significantly influence on trustworthiness and also trustworthiness effect on trust in learning and fun.

Currently, web-based online games is becoming popular in supporting learning process due to their effective and efficient tool. However, online games have lack of security aspect, in particular due to increase in the number of personal information leakage. Since the data are transmitted over insecure channel, it will be vulnerable of being intercepted by attackers who want to exploit user's identity. This paper aims to propose an online web-based educational game, Vidyanusa which allows the students to register their personal information using a unique code, a user name and a password. It manages the users according to their schools, subject teachers and class levels. In addition, by adopting a unique code, the confidentiality of the user identity can be kept away from attackers. Moreover, in order to provide a secure data communication between client and server, Secure Socket Layer (SSL) protocol is adopted. The performance of the system after implementing SSL protocol is examined by loading a number of requests for various users. From the experiment result, it can be concluded that the SSL protocol can be applied to web-based educational system in order to offer security services and reliable connection.

This study focuses on combining traditional craft lacquer thread sculpture and augmented reality (AR) technology to develop digital educational content. In this way, we not only make it easier and easier for children to learn and understand the traditional craftsmanship of lacquer thread sculpture, but also finds a new direction for traditional craft education. First, through literature research, the production process of traditional craft lacquer thread sculpture is summarized. Through an in-depth understanding of traditional craft lacquer thread sculpture, it provides a theoretical basis for subsequent AR digital content development to achieve educational goals. Next, we used AR technology to design and produce the digital content of the traditional craft lacquer thread sculpture. This study proposes the application of AR technology and the design and production methods of digital content. It is hoped that the methods and experiences we have proposed will not only provide reference for the development of similar digital content in the future, but also provide new educational methods for the inheritance of traditional crafts.

This study aims to investigate the Learning and fun aspects of dance games by examining their instructive values. Dance Central 2 was analysed with a focus on its educational functions by observing dance moves. Therefore this study looked into the game's educational elements that create learning effects and fun elements that attract continuous and voluntary participation. Analysis was implemented based on the physical, cognitive, and emotional aspects for Learning elements and the aspects of graphics, sound, video, rewards, target-setting, difficulty levels, and control for fun elements. As a result, it was found that the practice and performance modes of Dance Central 2 have elements that can improve players dance skills. Of course, there may be difference in players' participation and effects depending on their goals and objectives. Consequently, the continuous use of the dance game supported by player's dance skills and commitment will improve learning.

Recently, a variety of methodologies based on the use of educational coding robots have been proposed and experimented in newly emerging korean educational coding markets. Due to imprecise movement accuracy of the existing coding robots, however, such robots are mainly used as a toy. Inspired by these observations, we developed a simple adjustment method during robot movements, which is based on the observation results of 6 line-tracking sensors: 3 sensors in the center of a robot and other 3 sensors at the front. These sensors help to determine whether the robot is in the right location and whether it rotates as expected. Through the well-designed experiments, we report the effectiveness of our proposed solution: the average distance error of 1.57cm and the average degree error of 2.38 degree before and after complex movements. In near future, we hope our method to be popularly used in various educational coding robot platforms.

As the development of IT technology and Web services have changed recently, education environment combined with high-tech digital content is becoming a new trend with the demands of educational consumers. In Korea, however, there is no systematic discussion on the issue, and there is not enough evidence to verify the effectiveness of the research. Therefore, we will systematically analyze the educational effects of Digital Storytelling to create an educational environment that meets the new horizon of intelligent web and personalized service provision in the Web3.0 era, In this study, 12 domestic experimental studies that verify the educational effects of digital storytelling were systematically analyzed, compared with overseas cases, and proposed development plans in the Web3.0 era.

The purpose of this study is to analyze cases on teaching solutions exploration of Wythoff's game through using the analogy for the gifted elementary students, to suggest useful teaching methods. Students recognized structural similarity among problems on the basis of relevance of conditions of problems. The discovery of structural similarity improves the ability to solve problems. Although 2 groups-NIM game with surface similarity is not helpful in solving Wythoff's game, Queen's move game with structural similarity makes it easier for students to solve Wythoff's game. Useful teaching methods to find solutions of Wythoff's game through using the analogy are as follow. Encoding process helps students make sense of the game. It is significant to help students realize how many stones are remained and how the location of Queen can be expressed by the ordered pair. Inferring process helps students find a solution of 2 groups-NIM game and Queen's move game. It is necessary to find a winning strategy through reversely solving method. Mapping process helps students discover surface similarity and structural similarity through identifying commonalities between the two games. It is crucial to recognize the relationship among the two games based on the teaching in the Encoding process. Application process encourages students to find a solution of Wythoff's game. It is more important to find a solution by using the structural similarity of the Queen's move game rather than reversely solving method.
