Software education is required from elementary schools to prepare students for the fourth industrial revolution, which aims to improve algorithmic thinking. In general, teaching is divided into two stages: using a flowchart to design algorithms and implementing them through programming. However, converting a flowchart into code and checking the results in an educational programming tool is time consuming and requires additional programming activities. This study proposes a tangible coding tool that enables elementary students to convert algorithms designed at the unplugged activity into educational programming tool codes. This tool was developed in order for students to design algorithms at the level of assembling paper blocks and input them into a programming tool by taking a picture. Sixth graders were participated in this activity to evaluate its usability.

Unplugged computing, the teaching and learning method, helps you learn the principles and concepts of computer science, and its advantage is that even elementary school students can easily understand it. Most of the North Korean Defector specialized alternative schools in the country have the purpose of having their students pass the qualification exam and be admitted to college. Therefore, the data, or information courses, are comprised of simple typing practices and basic office program handling. The purpose of the present study is to offer a teaching plan for these North Korean refugee adolescents, and we had assessed the courses in terms of its effectivity through a verification process. As a result, during the stage where we analyzed the answers from surveys, that they considered suggested curriculum for these specialized North Korean refugee alternative school was appropriate and have the potential to increase the student's satisfaction and interest.

In this study, We made Computing Stories as a part of the new method of SW education. Also, we have developed unplugged activities using coding stories. We analyzed changes in learning motivation and academic achievement in the core concepts of CT by applying classes to elementary school students. For the development of coding stories, we conducted a questionnaire analysis of 11 expert groups to derive the core concepts of computational Thinking. Using the core concept of Computational Thinking, we developed a coding stories and unplugged activities linked with coding stories. It was confirmed that the score of the core concept of CT before and after class increased from 54.44 to 83.10 and the learning motive was also improved from the average score of 103.48 to 110.44. The results showed that the Coding Stories were effective in the students' Computational thinking achievement and SW learning motives.

Unplugged has been widely used as an instrument for teaching the basic principles of Computer Science. We'll present 'the binary system teaching contents for the characters' developed for the elementary. And they will successfully guide the student to understand the characters using in computer system. The activity-based learning is provided for describing characters with coding and decoding rules, and the using will be found out in everyday life. To check the adequacy of these materials they were tested to the elementary classroom, and the results showed effectively at Knowledge, Attitude, Generalization levels.

Currently computer education has been emphasized improving thinking skill instead of practical education of applied software. There are various studies that are to teach algorithm with visualization learning materials or activitives-centered unplugged class. However, algorithm classes for elementary school have various difficulties. One of the reasons is insufficient learning materials and teaching methods. Therefore we designed a activities-centered algorithm class for elementary school students. We hope this study will contribute to the study of algorithm classes for improving kids' thinking skill.

Unplugged has been widely used as an instrument for teaching the basic principles of Computer Science. This study presents the teaching contents developed for the children without any knowledge of binary numbers. which successfully guided them to understand the natural number binary system. The level of the pre-lesson for this learning requires counting numbers, matching numbers with cards, and arranging numbers. The activity-based learning is provided for describing natural numbers with the binary system and finding out them in everyday life. To check the adequacy of these materials on their organization and assessment they were tested at the classroom, which showed effective about the knowledge, the attitude and the generalization.

In this study, teaching-learning activities were developed based on computational thinking (CT) in high school Earth Science I Solid Earth domain. And their effects and implications were examined. To this end, 8 sessions unplugged activities based on problem solving were developed, and applied it to 65 high school students. As a results, significant changes have been were confirmed in both student's perception about CT and CT. After that, based on student's responses to self-reports and interview, the affecting factors for perception about CT and CT in the earth science problem solving process were investigated. In addition, implication that should be considered in terms of design and progress of teaching-learning based on CT were derived. Based on these results, the necessity and operation of teaching-learning activities was suggested for developing CT through various subjects including earth science.

CS Unplugged education is emphasized as the component of the basic principles of Elementary SW education. This document produced by two other Timbell presents the contents in a variety of topics about computer science. One of the main components is the finite Automata, and this requires the development of educational materials for teaching our situation. So We'll present the finite Automata learning materials for elementary school classes. Learning model that we have presented is a process of self-directed and activity-based learning. For verification of this experiment was the validation of the expert group and was concluded that adequate through the analysis of the diagnostic tests.

In order to cultivate AI(artificial intelligence) manpower, major countries are making efforts to apply AI education from elementary school. In order to introduce AI education in elementary school, it is necessary to have a curriculum and educational content for elementary school level. This study developed educational contents to experience the principle of AI learning at the unplugged level for the purpose of AI education for elementary school students. The educational content developed was selected as an AI that evaluates the emotion of sentences. In addition, to solve the problem, data attributes were derived and collected, and the process of AI learning was simulated to solve the problem. As a result of the study, the attitude of elementary school students to AI increased post than before. In addition, the task performance rate was averaged at 85%, showing that the proposed AI education content has educational significance.

The purpose of this study is to explore the educational effect by developing and applying a decision tree-based artificial intelligence convergence education program. To achieve the purpose of this study, the study was conducted through a three-step process of preparation, development, and improvement. In addition, it consisted of four stages of the creative problem-solving process: 'Understanding the problem', 'Idea search and development', 'realization' and 'evaluation'. In particular, the artificial intelligence convergence education program developed in this study is an unplugged activity that does not include programming. Therefore, it is very noteworthy that artificial intelligence convergence education was implemented in subjects other than technology and home economics education, and information education, which are part of junior engineering education, and practical arts education in elementary education, which is a subject that learns Artificial Intelligence technology including programming during class time. In other words, it shows that AI technology can be integrated and taught in most subjects, not specific subjects and has great significance in that it can utilize the concepts and principles of artificial intelligence technology when teaching the concept of classification, which is included in the curriculum.
