정보교과는 컴퓨터과학적 지식과 기술의 탐구와 더불어 실생활의 문제 해결을 위해 새로운 지식과 기술을 창출하고 이를 통합적으로 적용하는 능력과 태도를 함양하는 교과이다. 2015 개정 교육과정에서 정보교과의 교과역량 중 하나가 협력적 문제해결력이다. 정보교육을 통하여 배울 수 있는 프로그래밍 분야에서 강조하는 역량 역시 협력이다. 본 연구는 정보교과의 관점에서 협력적 문제해결력 측정 방식을 깃허브, 스택오버플로우의 사례와 PISA, ATC21S의 평가사례를 비교하고자 한다. 협업을 통한 더 나은 결과물을 도출해내는 프로그래밍의 과정을 통하여 협력적 문제해결력을 살펴볼 수 있는 토대를 마련하는데 의의가 있다.

In recent years, parents of students and government have been taking a growing interest in education for the gifted students and there are many research reports about the gifted education. Most of the reports, however, focuses on the conceptional feature of the gifted education program such as organization, operation, management, evaluation, etc,. In other words, there are very few researches on instructional materials for gifted students even though the materials is a critical factor for successful education programs. So, this paper introduces a lecture notes used in a personal education for gifted students to contribute in developing education contents in computer science area. The instructional materials titled as "The Necessity and Application of Matrix in Computer Science" is based on linear equation to usher the students into creative problem recognition and groping for solutions. Also, the instructional materials is useful for students to understand the tight mathematics-computer science relationship and the basic concept of liner algebra.

In this paper, we have selected physical computing as the focused learning elements with the PBL-based programming instruction method. Students experienced physical computing by using Arduino. Development of robot using Arduino can create an effective educational environment and also provide solutions for lack of environmental conditions, such as time or spatial factor restrictions and excessive expense issues; these are major obstacles to developing robot programming education. Finally, we analyzed the effects on growth of student's logical thinking and problem solving abilities by demonstrating the Arduino application courseware to the field of education.

Development of computer and internet has permitted cyber education transcending time and space, which escapes traditional classroom. As a result, the study of learner's own leading in Web-based instruction environment can be possible. In order to perform it effectively, suitable helps and advices, called scaffolding, must be offered. In this pater, we select a principle of computer in information technology basic subject of technical high school, and design and implement the web contents that provide the proper scaffolding for learners.

The curriculum system and documentation for advanced general education, MSC (Mathematics, Basic Science, Computer Science), and engineering-design courses have been developed to improve the education of advanced undergraduate students in engineering and technology at Chosun University. In this paper, to obtain improved quality of engineering courses, we systemized the education of engineering and technology, which could be designed as the education satisfying students and provide awards for high-quality performance, through efficient management of education courses and establishment of basic and professional courses. In addition, by applying evaluation to the engineering courses and using the model of continuous quality improvement, we could achieve a high-quality education system for the engineering and technology courses.

In this paper, we propose a Designed and Developed home router management system. Through the fourth industrial revolution and development of IoT technology, now people can experience a wide range of IoT related services at their workplace or daily lives. At the industrial site, IoT devices are used to improve productivity such as factory automation, and at home, IoT technology is used to control home appliances from a remote distance. Usually IoT device is integrated and controlled by the router. Home router connects different IoT devices together at home, however when security issues arise, it can invade personal privacy. Even though these threats exist, the perception for home router security is still insufficient. In this paper, we have designed and developed home router management system using DEVS methodology to promote the safe use of home router. Through the DEVS methodology, we have designed the system and developed the mobile application. This management system enables users to set up security options for home router easily.

최근 유비쿼터스 컴퓨팅의 관심이 증대되면서, 방대하고 다양한 형태의 데이터에 대한 효율성과 효과성을 고려한 지식 탐사방법연구의 필요성이 제기되었다. 기존의 지식 탐사방법에 대한 연구들은 방대한 비공간 데이터들의 지식을 효율적으로 탐사하고자 하였다. 그러나 기존의 연구는 탐사된 지식의 효율성안을 고려하여 유용한 지식탐사를 보장하지 못하는 문제점을 가진다. 따라서 본 논문은 공간 데이터 타입을 포함하는 대용랑의 데이터들로부터 효과성을 보장하는 특성화 지식 탐사방법을 제안한다. 본 논문에서 제안하는 특성화 지식 탐사기법은 공간 및 비공간 데이터들의 특성을 나타내는 요약된 지식을 제공하며, 밀도 기반의 클러스터링 기법을 적용하여 특성화 지식 탐사의 효과성을 높인다.

Data mining and knowledge discovery techniques have shown to be effective in finding hidden underlying rules inside large database in an automated fashion. On the other hand, analyzing, assessing, and applying students' survey data are very important in science and engineering education because of various reasons such as quality improvement, engineering design process, innovative education, etc. Among those surveys, analyzing the students' views on science-technology-society can be helpful to engineering education. Because, although most researches on the philosophy of science have shown that science is one of the most difficult concepts to define precisely, it is still important to have an eye on science, pseudo-science, and scientific misconducts. In this paper, we report the experimental results of applying decision tree induction algorithms for analyzing the questionnaire results of high school students' views on science-technology-society (HS-VOSTS). Empirical results on various settings of decision tree induction on HS-VOSTS results from one South Korean university students indicate that decision tree induction algorithms can be successfully and effectively applied to automated knowledge discovery from students' survey data.
