We enter the age of "a software revolution. The core competence for people living in these times as based on software competence to tackle the problem in computational thinking. Solve the problem of the basis of computational thinking to cultivate these competences to adopt a programming. As a result, this text to study is raising the computational thinking competencies for software training in recognition of the need to learn. A couple of times to develop content for the purposes of computational thinking competencies, Two based on the opinions of experts across extract the contents of a computational thinking. Further, these studies based on accident, we look forward to develop in the process of computational thinking competences.

There is a hot debate about what the core competencies of future generations, who have to live an uncertain future, should cultivate. The future society is expected to become a Software-oriented Society driven by software. Under these circumstances, interest in software education is exploding around the world, and interest in cultivating computational thinking through software education is also increasing. Also, discussions about what computational thinking is and what competence factors are made up are in progress. However, the research on the relationship between the competence factors of computational thinking is relatively insufficient. In order to solve this problem, this study proceeded as follows. First, five competence factors of computational thinking were selected. Second, we defined a path model to analyze the relationships among the competence factors of computational thinking. Third, we chose a test tool to test computational thinking. Fourth, the computational thinking tests were conducted for 801 students in grades 3 through 6 of elementary school. Fifth, implications were derived by analyzing various viewpoints based on the results of the computational thinking test.

There is a great deal of effort to improve Computational Thinking in education. In this paper, we define the relationship between SW capability and Computational Thinking, and then examine the current status of pre-service teacher's computing thinking. For this purpose, a survey about the attitude toward SW education and computing thinking was administered to prospective teachers who learned Entry software for one semester. The results of the survey showed that the improvement of abstraction, data analysis, and automation among the pre-service teacher's computing thinking is needed. When educating preliminary teachers, we can see that we need an education method that can increase the analysis and design capability beyond the Entry Software development tool.

Wing, J. M. emphasized the importance of computational thinking competency to live in the 21st century. In this study, the abstraction of computational thinking is classified into object abstraction, data abstraction, and procedural abstraction through related studies. In addition, abstraction achievement and assessment standards were developed for the abstractable competency assessment. As a result of applying to the school site, the students showed that the object abstraction and the data abstraction competency which are expressed in writing and drawing, they are excellent in solving the problem. However, students hard to write a computer program. The abstractable competency assessment developed in this study will help teach students to teach software education.

The purpose of this study was to design a competence teaching-learning model that could help college students improve their computational thinking among core competences in SW education. A competence teaching-learning model, UDDPAAP (Unplugged-Demonstration-Decomposition-Pattern Recognition-Abstraction-Algorithm-Programming), was designed by analyzing competences of learners with no experience in software coding, by reconstructing DMM, DDD, and DPAA among the five existing SW-based teaching-learning models, and by analyzing unplugged activity and the Bebras challenge computational thinking scale carefully. The unplugged activity partially adapted to instruction for college students and some items chosen from the Bebras challenge computational thinking scale were applied to the existing teaching-learning model. To determine the effects of the study, pretest was conducted in freshmen for computational thinking and self-confidence on the basis of the experience in SW and computer information literacy education, and posttest following instruction applying the UDDPAAP teaching-learning model. The students provided with SW education based on the UDDPAAP teaching-learning model saw their computational thinking competence improved.

2015 개정 교육과정에서는 컴퓨팅 사고력을 핵심 역량 중 하나로 설정하였으며 역량 함양을 위해 문제해결과 프로그래밍, 컴퓨팅 시스템영역에서 각각 프로그래밍 교육과 피지컬 컴퓨팅을 편성하였다. 또한 선행연구를 통해 효과성을 알 수 있었지만 연구의 편차로 인해 피지컬 컴퓨팅이 가지는 교육적 효과크기에 대한 검증의 필요성이 제기되나 관련연구가 진행되지 않았다. 따라서 본 연구에서는 피지컬 컴퓨팅의 동향 및 효과 분석 연구의 부분으로 피지컬 컴퓨팅 도구 및 프로그래밍 언어의 활용 동향을 분석하고자 한다.

A SW competency based on computational thinking is considered as one of the core competencies in the future society. However, the concept of computational thinking is difficult to be introduced to the class because of the lack of appropriate educational program and the shortage of proper understandings of students and teachers. Thus, we have applied computational thinking based STEAM program and analyzed its effectiveness to explore the educational possibilities of computational thinking. The 49 samples were selected, 23 for the experimental group, and 26 for the control group. Pre-post tests for integrated thinking abilities and computational thinking were done to explore the CT-STEAM program's effectiveness. As a result, the components of integrated thinking abilities, science preference and self-directed learning abilities were enhanced after CT-STEAM instruction. In addition, computational thinking assessment score was statistically significant. We expect new STEAM programs using various computing tools to be developed in the future.

Given the background of so-called 'the 4th industrial revolution', universities practice computing education for non-majors to equip them with computational thinking(CT). Universities apply different courses but researches analyzing effectiveness of the courses based on CT are limited. This research is conducted to understand a computing course for non-majors is effective in terms of CT. A CT based evaluation framework is designed referring to AP Computer Science Principles. Questionnaires are developed based on the framework and applied to the course participants. As results, students' post scores are significantly higher than pre scores. In addition, there are significant differences in pre-test scores by major category while there is no difference in post-test. Humanity & social science group showed the largest difference between pre and post results with science & engineering and computer in order. In sum, it is found that this course is effective to facilitate students abilities in terms of CT, particularly for the non-computer majors.

인공지능 기술의 발달과 함께, 4차 산업 혁명에 관한 사회적 논의가 이슈화됨에 따라 교육 학계도 변화의 목소리를 높이고 있다. 지식기반 사회에서 컴퓨터 활용 역량이 강조되면서, 코딩/소프트웨어 교육 등 테크놀로지 기반 교수학습이 교과목과 관계없이 주목받고 있다. 최근에는 오픈소스를 만드는 사람들에 대한 긍정적 인식이 생겨나면서부터, 그들을 메이커라 지칭하고 메이커를 양성하기 위한 운동이 확산되기 시작하였다. 학계에서도 이 운동을 수용하려고 시도하였으나, 관련 연구에서는 기존 테크놀로지 기반 교수학습과 구분되는 특성을 명백하게 보여주지 못했다. 본 연구는 메이커 교육의 시론적 연구로서, 이재호와 장준형(2017)이 제안한 메이킹 역량을 중심으로 이를 키워줄 수 있는 피지컬 컴퓨팅 교구를 조사하였고, 동시에 활용 가능성을 제안하였다. 초기에 제안된 교구의 활용방안은 현장 교사 3인의 전문가 검토를 받았으며, 그들이 제공한 조언을 참고하여 수정하였다. 보완된 활용방안은 메이킹 역량을 구성하는 분석역량, 설계역량, 구현역량으로 구분하여 제시하였다. 이를 통해 메이커 교육의 이론적 발전과 확산에 기여하고자 하였다.

The KAIE computing system curriculum consists of information equipment, operating systems, and information and communication fields, and covers basic understanding and principles of computer science. The role of the teacher is important to achieve the curriculum achievement standards. Therefore, we examined the factors affecting the teaching capacity of the KAIE computing system curriculum. The results of this study show that the teaching methods of teachers through the literacy of information and communication technology have a statistically significant effect on the teaching competency of the computing system curriculum. Also, male teachers perceived higher perceived factors than female teachers. The differences in teaching competency between teacher groups of less than 5 years and less than 5~10 years were significant. Based on these results, it is necessary to develop collaborate SW teaching strategies and mentor - centered training programs that can strengthen ICT and SW professors' competence and encourage participation of low - career teachers and female teachers.
