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.

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.

Arduino makes it easy to connect objects and computers. As a result, programming learning using physical computing has been proposed as an effective alternative to SW training for beginners. In this paper, we propose an Arduino-based physical computing education method that can be applied to basic programming subjects. To this end, we propose a basic programming training method based on Arduino analog signals. Currently, physical computing courses focus on digital control when connecting input sensors and output devices in Arduino. However, the contents of programming education using analog signals of Arduino boards are insufficient. In this paper, we proposed and tested the teaching method used for programming education using low-cost materials used for Arduino analog signal-based computing.

사물과 컴퓨터의 연결이 쉬워지면서 피지컬 컴퓨팅을 활용한 학습은 초보자들을 대상으로 하는 프로그래밍 교육에 있어 제기되는 문제점들을 보완하기 위한 좋은 대안으로 제시되고 있다. 본 논문에서는 초보자들을 위한 기초 프로그래밍 강좌에 적용할 수 있는 교육방법을 제안한다. 이를 위해, 피지컬 컴퓨팅 방식으로 기초 프로그래밍 강의를 진행한다. 현재 피지컬 컴퓨팅 강좌들은 대부분 다양한 입력 센서 연결방법과 출력장치 제어에 초점이 맞추어져 있다. 그러나, 피지컬 컴퓨팅 재료들을 이용한 프로그래밍 교육 내용은 그 사례가 부족하다. 이에 본 논문에서는 피지컬 컴퓨팅에 사용되는 저가의 재료들을 이용하여, 프로그래밍 교육에 활용한 교육 방법을 제안하고 시험하였다.

This study examined three elementary school computing curriculum - the CSTA K-12 computer science standards, the computing programme of the national curriculum in England, and the 2015 national curriculum in Korea - focusing on the educational objectives with the perspective of the revision of Bloom's Taxonomy of Educational Objectives. The CSTA K-12 computer science standards mainly addressed applying procedural knowledge and using digital technology is the main theme. The computing programme in England concentrated on understanding factual and conceptual knowledge of computer science, such as algorithms. The 2015 national curriculum also addressed applying procedural knowledge, but the main focus is making softwares and robots. The findings of this comparative analysis suggest that it is needed to set up concrete educational objectives for lower grade and make them related to the secondary education to make more coherent elementary-level learning objectives. And elementary-level computing learning objectives are needed to be organized with the perspective of knowledge and cognitive process level.

Along with a variety of coding education, physical computing education for controlling various sensors is being actively conducted for elementary, middle, and high school students in line with the era of the fourth industrial revolution. A problem with physical computing education using Arduino is pin connection errors between Arduino and various sensors. Most of the students who come into contact with the Arduino for the first time often do not know the purpose of the Arduino pin and the connection position of the pin. Also, hardware built with incorrect pin connections to the Arduino board often does not work properly. If this case continues, students will lose interest in coding education. Therefore, in this paper, we implemented an augmented reality application that informs the connection process of the Arduino board and the sensor during physical computing coding education using Arduino, and designed and implemented educational content for the Arduino pin position and connection process. First, we explain the role of the Arduino board and the sensor and the location of the pins. After that, the students run the educational augmented reality educational content using their smartphones and check the correct pin connection process between the Arduino and the sensor. In the physical computing education, augmented reality content is used to increase the understanding and immersion of the class. It is expected that the educational effect will also increase by inducing fun and interest in physical computing coding education.

Recently, the Internet of Things is attracting attention as an important key technology of the 4th Industrial Revolution, and SW education using physical computing is suggested as a good alternative to supplement the problems raised by beginners in programming education. Among the many teaching tools that can be used for physical computing education, MODI is a modular manufacturing tool that anyone can easily assemble like Lego. MODI is a teaching tool that can improve learners' achievement by linking a self-linked block-type code editor called MODI Studio to lay the foundation for programming in a relatively small amount of time and immediately check the results in person. In this paper, a physical computing education method using MODI was designed to be applied to basic programming courses for programming beginners and applied to after-school classes for middle school students. As a result, it was found that students' interest and satisfaction were much higher in physical computing classes using MODI than in text-based programming classes. It can be seen that physical computing education that allows beginners to see and feel the results in person is more effective than grammar-oriented text programming, and it can have a positive effect on improving basic programming skills by increasing students' participation.
