In the knowledge-based society, IT literacy and application of a person become a measure of personal competitiveness. As IT industry is of great important nationally, many countries are trying to make an effort to promote IT industry. In this sense, identification and fostering of the gifted children in IT become an important national task since, in IT industry, usually only a few prodigies have led whole IT industry. Currently gifted education aims for convergent gifted education according to government policy. The purpose of this paper is to investigate correlation of information subject and convergent subject for the gifted children in IT. For this purpose, the gifted children in IT who attended a gifted science education center attached to a university at Seoul Metropolitan Area are selected. Their grades during their the period of attendance are collected and analysed. The statistical results show that there is a meaningful correlation between information subject and convergent subject for the gifted children in IT. It means that the higher scores information subject is, the higher scores convergent subject is. The results can be used to make or change gifted curriculum and education contents for gifted IT education.
A Study on Development of Enhancement Guidelines of Smart Application Accessibility for the Disabled
전우천 한국정보교육학회 2015 정보교육학회논문지 Vol.19 No.1
n current information society, there is a barrier called digital divide. Due to this barrier, the disabled have difficulties to communicate with the world. Recently, with advanced smart techniques, smart devices become necessity for the disabled. Currently improvements of smart application accessibility become a great concern for the disabled. The purpose of this paper is to present some guidelines for enhancing smart application accessibility for the disabled. The enhancement guidelines are developed based on the existing mobile accessibility guidelines and modified for better adaptability for the disabled. Our principles are as follows: minimizing blue light emission from smart devices, automatic focus on input window, action trace, font color change, emergency notification by motion, gesture recognition, control location, scrolling avoidance, auditory service for visual warning, and icon literation.

The purpose of this paper is to identify the correlation of entrance score by observation and nomination system and performance assessment score for the gifted children in IT. In other words, the purpose of this paper is to investigate the reliability of observation and nomination system by analyzing and comparing entrance scores and performance assessment score during the period of attendance for the gifted children in IT. For this purpose, the gifted children are selected and analyzed in a gifted science center attached to a university at Seoul Metropolitan Area. The analysis results show that there is meaningful correlation between entrance score and performance assessment score. That is, if high scores in entrance exam means high scores in performance assessment scores. The result will be useful to trust and extend observation and nomination system for the selection of gifted children in IT.

현재 영재교육은 정부방침에 따라 융합형태의 교육을 지향하고 있다. 본 연구의 목적은 정보영재아동에 있어 서 정보과목과 과학과목(물리, 화학, 생물, 지학)의 상관관계를 분석하는 것이다. 이를 위해 서울시내 한 대학부 설 과학영재교육원의 정보영재아동을 대상으로 재학기간의 성적을 바탕으로 분석하였다. 통계분석 결과 정보과 목과 생물과목의 상관관계를 보여주었다. 즉 정보과목을 잘하면 생물과목도 잘하는 것으로 분석되었다. 나머지 물리, 화학 및 지구과학과목에 대해서는 상관관계가 없음을 나타내었다. 본 연구결과는 향후 정보영재교육에 있 어서 과학과목의 비중, 교육내용의 구성 등에 중요한 기초자료로 사용될 것이다. Currently gifted education aims for convergent gifted education according to government policy. The purpose of this paper is to investigate correlation of information subject and science subject(physics, chemistry, biology, and geology) for the gifted children in IT. For this purpose, the gifted children in IT who attended a gifted science education center attached to a university at Seoul Metropolitan Area are selected. Their grades during their the period of attendance are collected and analysed. The statistical results show that there is a meaningful correlation between information subject and biology subject for the gifted children in IT. It means that the higher scores information subject is, the higher scores biology subject is. The results can be used to make or change gifted curriculum and education contents for gifted IT education.

With advances in information and communication technologies, everyone enjoys numerous social and economic benefits in his/her daily life. However, there are such unexpected side effects as internet addiction, infringement of personal information, cyber crime, copyright violation, hacking, and so on, Our society is to detect causes of such side effects and deal with those side effects as early as possible. The purpose of this study is to identify correlations between internet addiction and vocation. In order to achieve this purpose, 5 vocation types were chosen and correlations between vocation types and internet addiction were analyzed. Thorough statistical analysis, it was found that there are different internet addiction rate depending on vocation and that, however, there is no direct correlation between vocation and internet addiction. 정보관련 기술이 발달함에 따라 정보화는 현대인들이 누릴 수 있는 다양한 사회적, 경제적 혜택 뿐 아니라 예기치 못한 문제점을 야기하고 있다. 대표적인 문제점들로는 인터넷 중독, 사이버범죄, 개인정보유출, 저작권 침해 등이 있다. 우리 사회는 이러한 부작용들에 대해 원인을 발견하여 신속하게 대처해야 한다. 본 연구의 목적은 인터넷 중독과 직업별 상관관계를 분석하는 것이다. 구체적으로는 4년간의 인터넷 중독 조사 자료를 통해 5가지의 직업군 중에서 어떤 집단이 인터넷 중독에 더 취약한가를 분석하였다. 통계분석연구결과 직업과 인터넷 중독과는 유의미한 상관관계가 없는 것으로 나타났다. 즉 5가지 직업군 중 직업군 별로 인터넷 중독율의 높고 낮음은 나타났으나, 직업과 인터넷 중독은 통계적 상관관계가 없는 것으로 나타났다.
학습 장애학생의 주의집중향상을 위한 m-ARCS 모형기반 모바일앵커프로그램의 개발과 적용
전우천,김철호 한국정보교육학회 2010 정보교육학회논문지 Vol.14 No.4
장애학생들에게 주의집중은 매우 중요한 교육요소이다. 본 연구에서는 학습 장애학생들의 특성을 분석한 후, keller의 동기유발학습이론인 ARCS (Attention, Relevance, Confidence, Satisfaction)모델의 동기유발 요소와 정착학습이론의 앵커라는 자발적 인지학습을 위한 매개체, 그리고 방법적 측면의 모바일이라는 방법을 적용한 m-ARCS이론을 제시하였다. 또한, m-ARCS이론에 의해 구현한 모바일 앵커프로그램은 학습 장애학생의 특성을 고려하여 설계하여 그들의 주의집중력을 향상시킬 수 있다. 이처럼 m-ARCS이론에 의한 모바일 앵커프로그램을 구현하여 실제 학습장애 학생에게 적용한 결과, 첫째, 학습에 대한 재미와 흥미를 느끼며 동기유발 및 주의집중력이 향상 효과가 있었다. 둘째, 학습과정에서의 성공경험으로 인해 학습에 대해 전보다 자신감이 향상되었다. 셋째, 모바일 앵커프로그램을 통해 활동한 학습내용들을 자연스럽게 습득함으로써 기초․기본 학습능력이 향상되었다. In this paper, in order to improve concentration of learning disorder students, m-ARCS model is proposed. The m-ARCS model is based on the ARCS model that is the existing representative motivation support model. The model is designed on mobile environment, and to provide motivation and concentration to learning disorder students by allowing students to engage in various real-life activities. Based on the proposed m-ARCS model, a mobile anchor program is designed and implemented. The followings are concluded after applying the mobile anchor program to learning disorder students. First, students are highly motivated and concentrated by the program. Second, students gain confidence by feeling of success during their study. Third, their basic study ability is improved via the mobile anchor program activities.
