Although programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, as it requires logical thinking skills, it is recognized as a difficult subject even for SW major students. This difficulty occasionally causes SW major students to lose interest and confidence in their major during the introductory course of a programming language; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C language, and developed the examples of Scratch for exercising the concepts. The instructional model supports the progress model of learning first the programming concepts through Scratch and then expand the learning content into C language. We also conducted an experiment on the SW major freshman students of a local private university to verify the effectiveness of the model.

The purpose of this study is to describe the SW Convergence education class applying the Novel Engineering teaching method during the creative experiential activity time. We developed a SW convergence education program for a patriotism class applying Novel Engineering, a new educational method instead of writing and drawing. Through this lesson program, students can improve their problem-solving ability based on their computational thinking and enhance their love spirit about country. Students read a book that tells the story of patriot, writes the historical scene presented in the book through scenarios through Re-enactment, and implements the simulation situation using Lego WeDo 2.0. The results of this study based on the analysis of the data on the questionnaire showed that there is a significant students' change through the SW convergence education program for patriotism class. In the future, we will expand the scope to more various grades and subjects so that we can generalize the effectiveness of SW convergence education applying Novel Engineering.

This article discusses the possibilities and limitations of ICT education by reviewing the previous research on its various aspects including educational goals, contents, methods, and evaluation. First, when it comes to its educational goal, the prior studies suggest that ICT education aims to nurture digital citizenship among students and to enable them to participate in different sectors of our society. ICT education characterizes the core capacities of its future learners as 'lifelong learners,' 'information producers/consumers,' and 'local/global citizens.' Second, in regard to the educational content of ICT education, researchers investigate SW education importantly: They develop the educational programs and examine the effectiveness of those programs. However, to ensure the relevancy of the educational contents to the future society, institutional support is imperative including facilitating educators' capacities and synchronizing ICT education with subject education. Third, as the educational methods, various ICTs such as flipped learning and augmented reality (AR) are being applied to actual classroom teaching. Research on the educational methods, which is the most vibrant area in the ICT education scholarship, is expected to improve the previous educational methods and to lead the qualitative development of ICT education. Fourth, the previous discussion on the educational evaluation focuses on computer-based evaluations. Educational evaluation using ICT will enable educators to assess the characteristics and achievement of an individual learner accurately and to lead them to apply a teaching-learning process effectively, which will ultimately enhance the effectiveness of educational evaluation. Along with the overall review on the possibilities of ICT education, this article discusses the limitations of the current ICT education and its implications for educational inequalities.

The purpose of this study is to develop a Goldberg device-based software(SW) convergence Education tool. The 2015 revised curriculum emphasizes convergence with various subjects for effective SW education. In particular, physics is often used as a material for SW convergence education because it is closely related to computational thinking such as sequential movement, quantification of energy and simulation. In this study, we developed an educational program based on the Goldberg device that utilizes physical knowledge, concepts and manipulation. In order to verify the effectiveness of the program, the survey questions were developed through Delphi verification and a basic satisfaction survey was conducted based on this. As a result, the developed program can be effectively used as a program for SW convergence education.

Since the problem-based learning (PBL) shows the effectiveness of self-directed learning ability and internalization of learning motivation in the process of solving real problems, studies on PBL and application cases are actively pursued in the university education. This study analyzed the effects of PBL on the academic achievement and computational thinking in a non-SW major students' programming course. The programing course was divided into the PBL class and non-PBL class, and at the end of the classes, the scores of the exams and the results of questionnaires about the educational effectiveness and computational thinking were analyzed. As a result, the students in the PBL class, compared to those in the non-PBL class, showed significantly higher scores in the areas of the algorithm implementing skill, self-directed learning, problem solving ability, and continuous learning motivation.

In the case of Java programming education for non-major undergraduates, there are no examples of applying the physical computing education method. The advantage of physical computing education is that you can directly check the SW processing output result according to the input value of digital and analog sensor, so that you can quickly correct programming errors and improve learner's learning interest and satisfaction. In this paper, we use the microbits to combine physical computing education with basic Java programming education. In addition, according to the computational thinking process, we proposed an educational method for creating Java programs using microbits. Through block programming to control the microbits, we designed an algorithm and applied a training method to convert it into a Java program. In addition, the results of students' evaluations were analyzed in the course applying the education method, and the effectiveness of the education method using the microbit was analyzed.
