Due to recent various online problems, the necessity of information security education has increased. The information security education was strengthened thanks to the informatics curriculum of middle school in 2007, but the educational fields lacked detailed educational materials that could be utilized. Thus to give appropriate information security education for elementary and middle school students, this research developed an unplugged activity for them. The activity was designed by applying Lickona's integrated ethical model and design patterns of unplugged activities, and developed through expert's review and pilot tests targeted to elementary school students. Developed activity was applied to 21 middle school students and the usability was evaluated. As results, first, the activity showed similar expectations from the previous activities. Second, persistence was also similar or higher compared to the previous activities, so the activity developed from this research secured the minimum usability. The unplugged activity developed from this research would give implications in producing various educational contents for information security education.

The use of Unplugged Classes to easily teach the contents of Computer Science has recently become increasingly widespread. However, there has been a lack of research to discover which learner groups would benefit most from this method. Therefore, the intention of this research is to analyze learner's traits by examining score levels of post-class assessments made after Unplugged Classes. For this research, the learner's trait data has been divided into two groups: students' propensity towards computer comprehension and students' natural disposition. In addition to the verification of the relation between a learner's accomplishment level and the aforementioned data groups, meaningful applications of the data will also be recognized for practical use in elementary school classrooms. The results of this research will be valuable for elementary school teachers who utilize the Unplugged Class.

The 2015 revised curriculum offers elementary students an unplugged computing education as a way to learn the concepts and principles of computer science in an easy and fun way and to improve their computational thinking. Yutnori is a traditional board game unique to Korea, which contains various contents such as history, culture, and science of our people, which helps to cultivate cultural identity of learners, and can effectively promote cooperation and communication among members. In this paper, we examined the possibility that Yutnori could be used as an unplugged computing tool in elementary school software education and convergence education. Korean traditional board game Yutnori has elements that can learn the sun and movements of heavenly bodies as well as sequential, selection, and repetitive algorithm elements. Unplugged activities that apply Korean traditional culture Yutnori is expected to help foster creative convergence talents by improving elementary school students' computational thinking, communication and community.

Recently, the awareness of S/W education, which was confined to the profession, is changing due to the changing industrial environment based on ICT technology World main countries invest competitively in S/W education and the target age group is getting lower Among them, the unplugged coding method using the robot platform is known as one of the most effective S/W training methods targeting the elementary age by the intuitive coding method and the robot platform feedback. However, the unplugged coding method using the robot platform has a disadvantage that it can not configure various interfaces for complicated coding due to limitations of H/W. In this paper, we have proposed an unplugged coding system which can input various commands for robot control by IR remote control as an interface and minute signals using robot sensor.

In elementary school software education, a programming process is experienced through a simple problem solving process. And even this experience emphasizes that the problem-solving process is a CS Unplugged activity. However, CS Unplugged has a disadvantage in that it only learns the principles of computing, and the learner cannot experience real problem solving. In this study, a learning program using artificial intelligence robots was developed with the goal of cultivating the ability to solve problems encountered in the real life of elementary school students. Students could solve complex problems in real life from the point of view of artificial intelligence through the developed program, and increase their interest and understanding of artificial intelligence education through robot control.
