With the development of information and communication technology, information literacy and utilization are emerging as basic skills necessary for modern people. Accordingly, information education is becoming a basic literacy education for a nation. Unplugged computing is in the spotlight as a major educational method of information education. The main advantage of unplugged computing is that it is easy to convey basic theories or principles of computer science to students through play activities without the help of special information devices such as computers and tablet PCs. However, studies on student evaluation on unplugged computing have been very insufficient. In this study, students' evaluation standards are developed to maximize the educational effect of unplugged computing. The evaluation standards consist of four areas: participation, interest, satisfaction, and understanding of concepts. The results of this study can be used as a basic study for student evaluation of unplugged computing in the future.

The purpose of this paper is to develop an unplugged education program that develops the 4C (Creativity, Critical thinking, Communication ability, Collaboration) and CT (Computational Thinking) competencies required in modern society. This study discovered "Fine Dust Robot" as a theme suitable for the unplugged education program, and designed the Unplugged 4-hour education program which can develop 4C and CT competencies. The first stage motivates learning, and the second and third stages develop unplugged activity to develop CT. In the fourth stage, the algorithms created through unplugged activities were programmed through the natural language instruction card and produced the output. We developed educational materials that can be utilized in the unplugged education program. Finally, education programs were conducted for elementary school students, and pre- and post-tests of computational thinking were conducted for general students and gifted students. Educational effective was found in both groups.

In this paper, we conducted a case study for lower grade elementary school students by modifying and applying lesson plan of CS Unplugged v4.1. Software education was introduced in the 2015 revised national curriculum in Korea, but the starting age is later than the other countries. Also most projects and researches are concentrated in higher grade elementary school students. It is necessary to lower the entry age of software education in order to nurture human resources leading the fourth industrial revolution era. In this study, we modified the lesson plan of CS Unplugged v4.1 to be suitable for lower grade elementary school students in Korea. The participants were 18 students in the first grade of elementary school, pre&post-test on understanding of computer science principles were conducted for examining the effectiveness. As a result, the average was significantly higher in the post-test than in the pre-test, with t=-2.222, p=0.040(p < .05).

With the introduction of the 2015 revised curriculum, software education became mandatory in elementary school. The practical subject in the content for the software education consists of information ethics, algorithms, programming, and computer science. Especially, elementary school encourages the unplugged activities. Unplugged activities are preferred among the teachers in the education field as a teaching-learning method. However, those teachers pointed out that the lack of suitable unplugged activity materials was the biggest challenge. In addition, it was pointed out that the existing materials were not suitable for achievement standards, and there are many simple playing-oriented educations that are not linked to computing activities. In this study, we developed an unplugged activity-oriented robot that can be used for the elementary students to learn the basic control structure suggested in the achievement criteria SW education and to develop creative problem solving ability through various activities using sensors. The effectiveness was verified through the software class using the developed robot in this study.

Recent interest in software education has naturally led to interest in computer science. Computer science is the study of theory and principle of computer and computational systems. This knowledge and concept of computer science is fundamental to software education. Recently, "Computer Science (CS) Unplugged", which is an educational method for introducing students to concepts of computer science without using a computer, has been widely used in classes around the world. CS Unplugged is a method for learning the basic principles of computer science through diverse playing activities. The problem, however, is that these CS unplugged activities take place in class without an analysis of how closely they relate to the core subjects learned in real computer science. Therefore, in this study, we will study on the comparison between the core contents of computer science and the core contents of computer science contained in the various activities of CS Unplugged.
