This study proposed a new education program for the information science gifted talent using unplugged computing and EPL that are new teaching approach of computer science. We analyzed unplugged computing contents and developed the advanced educational program for the information science gifted talent. We also made up a curriculum and teaching strategy and applied the elementary information science gifted talents the developed program with unplugged computing. In order to verify an effectiveness of new program, we tested t-test and found the positive results between before and after the program as well as an experimental group and the comparison group. In interview and observation about the gifted talents, we also saw that the students evaluated an unplugged computing lesson to the positive responses. We expect the proposed unplugged computing program will give many help for teaching the information science gifted talent.

The purpose of this study is to statistically analyze the correlation between CS Unplugged education and the computational thinking of gifted and talented students. In this study, qualitative research was conducted for 17 students in 5th grade gifted class at an elementary school in the city of Yongin. Students participated in 10 hours of CS unplugged classes. Student questionnaire, class journals, student activity sheets, and student interview records were collected and qualitatively analyzed. In order to supplement the qualitative data, computational thinking ability tests were also administered. The results of the study are as follows. First, CS unplugged education plays an effective role in improving CT of gifted and talented students. Second, it was not every sub-area of CT that CS unplugged education brought statistically significant improvements in. Third, CS unplugged education is suitable to be presented as the first step of the SW curriculum for gifted and talented students.

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.

현재 우리나라는 소프트웨어(SW)에 대한 관심 증가에도 불구하고 초등 소프트웨어 교육을 위한 표준 교육 계획이 마련되지 않아 체계적인 교육을 통한 컴퓨팅 사고력 배양이 어려운 상황이다. 따라서 본 논문에서는 언플러그드 활동을 통해 컴퓨팅 사고력을 증진시킨 후 이를 바탕으로 코딩 문제해결능력을 향상시킬 수 있는 교육 콘텐츠의 필요성에 대해 인식하였고, 언플러그드와 블록 코딩을 연계한 초등 소프트웨어 교육 계획을 제안한다. 교육 계획은 소프트웨어에 대한 접근, 언플러그드 교육을 통한 컴퓨팅 사고력 향상, 코딩 교육을 통한 문제 해결 능력 향상 과정 등 총 3단계로 구성되었다. 개발된 콘텐츠의 매 주제는 언플러그드 교육과 코딩 교육이 서로 연계되도록 구성하여, 코딩 개념 학습 및 이와 연관된 컴퓨팅 사고력 향상 후, 학습된 내용을 코딩 과정에서 실체화 하도록 하여 응용력이 배양될 수 있도록 하였다.

SW education is being implemented in all the school due to the application of the 2015 Curriculum. The purpose of SW education is to improve Computational Thinking by using Unplugged Activities, Educational Programming Language, and Physical Computing. Among them, 73 domestic and 85 overseas researches related to 'Unplugged Activities' were compared and analyzed using semantic network analysis techniques. As a result, the research on 'Unplugged Activities' has been started from 1998, and the research has started in Korea since 2006. As the CT is recognized as a core competence for the future society in line with the 4th Industrial Revolution, researches have been rapidly increasing in both the domestic and overseas countries since 2016. In Korean studies, it was analyzed that many main words related to the elemental factors such as 'unplugged activity', 'robot utilization', 'educational programming language' were found. This suggests that future research should move toward research for the promotion of 'CT' which is the purpose of computer science.

This study aims to investigate the characteristics, concepts, types, and strategies of unplugged coding for young children based on computing thinking. The key to unplugged coding for young children is computing thinking. Unplugged coding based on computing thinking for young children can be used to solve problems that can be encountered in everyday life through playing games based on logical thinking by positively utilizing algorithm boards, s-blocks, coding robots, and smart devices without using programs And find new ways to play. Types of unplugged coding for young children include direct input to smart devices, using coding robots with dedicated apps, practicing coding procedures using algorithms, and using hybrid methods. Strategies include understanding algorithms, drawing flowcharts, dividing into smaller parts, finding patterns, inserting, and predicting outcomes.

The purpose of this paper is to study the unplugged educational program for the lower grades of elementary school. For this, the study was conducted as follows. First, a play-learning-based unplugged education method was discovered, focusing on play activities according to the level of development of elementary school students. Secondly, unplugged educational programs to develop Computational Thinking were designed according to the discovered topics. each class is conducted by storytelling, and the content of the storytelling is related to the integrated curriculum 'Winter'. In addition, each class was analyzed based on the core elements of Computational Thinking ability. And, we developed educational materials that can be used in the designed unplugged educational program. Finally, the educational program was applied to the lower grades of elementary school, and the educational program was analyzed through case studies. As a result of the analysis, the educational program was organized according to the level of the students, and it was confirmed that this educational program is helpful in improving the Computational Thinking of lower grade students of elementary school.

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.

This study analyzed the effect of an unplugged educational program which focuses on the algorithm execution time analysis on enhancing the computational thinking of the third grade students. An unplugged educational program was developed by following the procedures of the ADDIE model based on the result of the demand analysis conducted with 70 incumbent elementary school teachers and 120 third grade students. The developed program was applied to 24 third grade students for 36 classes in six days and a comparison was made through pre-post comparison tests with 24 students who were taught with a board game program for the same period of time. As a result, the unplugged education program which focuses on the algorithm execution time analysis is deemed to have positive effect on the computational thinking of the third grade students.
