We have developed a UMC (Use-Modify-Create) strategy for the improvement of computational thinking in SW education. UMC model is an instructional strategy that students analyze examples of algorithms, modify-expand it and to develop new SW. First, we applied the UMC classes during 1 semester targeting pre-service teachers. To explore the effectiveness of the proposed model, we conducted a t-test for improving students' self-CT. Through a result, we found that is the UMC teaching-learning strategy helped the CT concepts and practice skills. In addition, we could see the Use and Create steps help to improve the ability of students' CT than directly teaching and Modify steps.

The purpose of this study is to verify the effect of the design - oriented model (NDIS) for enhancing learner's computing thinking in SW education. NDIS is a project-based learning model in which learners find real-life problems, analyze their needs, and design and implement them. In order to verify the effectiveness of NDIS, we experimented with middle level G education university students who had previously experienced SW education class. The traditional project model was applied to the control group and the NDIS model based on CT was applied to the experimental group. The experimental group showed a higher CT narrative performance evaluation score than the comparative group, which showed a significant difference. In addition, students showed a positive perception of self-confidence and CT improvement in solving real-life problems using computing.

The researches on the concept of justice and utilization for Computational Thinking with SW education are being actively discussed. However, a program has developed in conjunction with the actual elementary curriculum is not much. In this study, we have developed an educational program in applied mathematics based on CT. First, a separated view for a CT Application of mathematical concepts and objectives are set in three different application models. In order to achieve the CT-based math lessons, we also have developed a teaching and learning materials. We applied the developed materials in class, and to evaluate the satisfaction of learners. In addition to the validation of school application, we conducted a survey of professionals and teachers. The results of the analysis, the data showed that are helpful in the development of the student' CT ability as well as the ability to be helpful teaching and learning in school.

Computational Thinking is one of the biggest issues in the era of the Fourth Industrial Revolution. It is a core literacy required not only for SW major but also for all students including them. It is not a simple computer software education, but a coding education based on Computational Thinking, and it should be able to solve the problems in everyday life and to express the process and solutions. However, in the case of students who lack background knowledge on SW and programming languages for development, it is hard to know how to algorithmize problems and express them using computer devices. In this study, we proposed a education course model to improve the students' thinking skills and to express them effectively. In addition, we confirmed whether the non-major students who learned through this education course model can express various problems related to the major field by integrating them with computing accidents and improve the problem solving ability.

The purpose of this study is to design and develop of digital contents to improve computational thinking in the online education environment. First, we planned the design and development of contents with 19 experts of Software education. Digital content was designed from the point of view of improving the educational quality and the quality of contents for the improve of computing thinking. The content type is classified into the SW education area; computer science, programming, physical computing, convergent computing, computing thinking, and software education that improves the computing thinking. And we designed 45 learning programs for each SW education area. Designed learning contents were developed in 464 lessons to suit the online education environment. The content validity of the proposed content was verified by the expert group and the average CVI value was over .83. Through this, we could analyze that the developed contents will help learners to expand their computing thinking.

Through the fourth industrial revolution and coronavirus pandemic situation, the necessity and importance of SW education are being emphasized more. However, it is difficult to achieve the effect of improving students' computational thinking skills by just 17th hour, which is organized in the 2015 revised curriculum. Moreover, due to the coronavirus pandemic situation that has continued since last year, there are environmental restrictions on the equal SW education for students at the educational site. In this study, the unplugged class using a completion robot was designed to reflect the current situation at the educational site and experience of SW education was provided to the 6th graders of J elementary school. Through the application of a class, we checked whether the unplugged class using robots affect students' perception of SW education and the use of computational thinking skills. As a result, the unplugged class using a completion robot showed that students used computational thinking to solve given problems and had a positive impact on changes in perception of SW education.

In this paper, we propose to discover the certification items and to study the content system for SW education instructors, including SW education based on basic teaching-learning capabilities and Computational Thinking(CT). To this end, SW education instructor qualification were divided into three classes using methods such as prior case studies, Delphi surveys, and expert meetings, and the certification evaluation areas were divided into large areas of 'Teaching and Learning Method' and 'Software Education' reflecting primary and secondary curriculum. Sub-areas and content elements for each series were set and verified through expert Delphi survey. Such research is expected to contribute to the spread and dissemination of SW education by being used meaningfully when establishing a system that fosters SW education instructors and maintains and manages the quality of instructors.

The purpose of this study is to analyze the teachers' perceptions about the various evaluation methods used in SW education and to find ways to improve the usefulness of the field. To do this, we surveyed the teachers who were educated about SW education evaluation. As a result of the study, it was recognized that the use of output, portfolio, and observation evaluation in SW education class is suitable for evaluating Computational Thinking(CT) and useful for field application. On the other hand, paper and self-evaluation are useful for field application, but they are relatively inadequate to evaluate CT. Portfolio, design, and interview evaluations are good for measuring CT, but they are difficult to apply to the field. Also, evaluation criteria, evaluation factors, and strategies were found to be difficult to apply. Therefore, we suggest the necessary measures to apply SW education evaluation method more effectively.

Maker Activity based Design-Thinking 5 Step is a better experience for providing the public with a better approach to design by sympathizing with human needs and exploring the public's potential desires. This paper studied the teaching method by applying the value of the Maker Training that emphasizes the importance of sharing and opening results with others after creating them based on the ideas of the learners using different tools, the basic mind of Design-Thinking with the observation and empathy about human beings and the derivation of user-centric results to the SW coding curriculum. For this purpose, we studied teaching methods by Design-thinking based on sections that require coding in the information classes of the secondary school curriculum. We demonstrated the class to a group of education experts by applying the syllabus of instruction. Then we collected evaluations and opinions of the experts and we modified the syllabus to reflect the collected assessment. Under the Design-thinking 5 step foundation, classes were demonstrated with a group of education experts, opinions collected, and suggestions collected were reflected on the assessment outcome. I think that It is an effective training opportunity to practice a widespread idea that enables infinite thinking and a convergence of thinking that brings out the best decision from a widespread idea.
