Computational thinking is generally defined as the mental skills that facilitate the design of automated processes. Computational Thinking is being considered as a critical skill for students in the 21st century. It involves many skills, but programming abilities seem to be a core aspect since they foster the development of a new way of thinking that is key to the solution of problems that require a combination of human mental power and computing power capacity. In this paper, we explore how computational thinking conception are changing. We also explore how to identify the psychological and behavioral nature of learners through SW education.

The purpose of this research is to suggest the method of code analysis for evaluating learners' projects in computational thinking(CT) education. Recently, block programming tools are applied to K-12 SW education, this study considered the assessment method for evaluating students' levels and learning about CT concepts through analyzing codes of the Scratch projects that students created. As a result from the analysis of 45 projects of novices, it showed the bad coding patterns of novices and verified that it is possible to evaluate students' learning about CT concepts through the analysis of their codes. The higher learner's level, the greater scores of logical thinking, synchronization, flow control, and data representation. This result is able to apply to student assessment of CT concepts in K-12 SW education.

In this paper, we propose the effect of project-based robot education program on the interest toward robots and the computational thinking of elementary school students. Software education is being actively carried out around the world in order to cultivate software talents in accordance with the 4th industrial revolution. As a result, the importance of robots in education has increased, and education using robots has been actively introduced. However, the activities of simply assembling and repeating robots in schools were not effective in enhancing elementary school students' interest toward robots and computational thinking. Therefore, it is necessary to overcome traditional teaching-learning methods and to develop robot education. So, in this study, the robot education program that introduces project-based learning was developed for improvement of interest toward robots and computational thinking of elementary school students. In order to verify the developed education program, 114 elementary six grade students were selected as research subjects and the traditional teaching-learning method and project-based learning were applied to the experimental and control group. As a result, project-based learning was more effective for elementary school students' interest toward robot than traditional teaching-learning method. In computing thinking, the experimental group showed a significant improvement, but there was no statistically significant difference in the post-test.

This study aims to suggest lesson plans and evaluation methods for primary pre-service teachers by reviewing the concept of computational thinking(CT) skills and its sub components. To pursue this goal, a literature review has been conducted in regards to CT and the effectiveness of programming courses. In addition, the Scratch educational programming functions were analyzed yielding six CT elements(data representation, problem decomposition, abstraction, algorithm & procedures, parallelization, simulation). With these six elements, one semester lesson plans for 15 weeks that represent the connections with six CT elements were designed. Based on the PECT(Progression of Early Computational Thinking) model and the CT framework a rubric to evaluate learners' proficiency levels(basic, developing, proficient) revealed in their final projects was developed as well. Upon a follow-up empirical study, the lesson plans and the rubric suggested in the current study are expected to be utilized in teachers' colleges.

Today, a computational thinking course is being introduced in elementary, secondary and higher education curriculums. It is important to encourage a creative talent built on convergence of computational thinking and various major fields. However, proper analysis and evaluation of computational thinking assessment tools in higher education are currently not sufficient. In this study, we developed a rubric to evaluate computational thinking skills in university class from two perspectives: conceptual learning and practical programming training. Moreover, learning achievement and relevance between theory and practice were assessed. The proposed rubric is based on Computational Thinking Practices for assessing the higher education curriculum, and it is defined as a two-level structure which consists of four categories and eight items. The proposed rubric has been applied to a liberal art class in university, and the results were discussed to make future improvements.

Computational thinking has been a powerful key recently to open a new paradigm era in the curriculum of Informatics subject and the community of computer science education. But the quality and quantity of domestic research about it has been very poor in comparison with other countries. Therefore, this study focuses on the definition, learning steps and learning contexts about computational thinking education using some professional questionnaires and analyses of related other countries' literatures. The learning contexts that were extracted by several previous works could be used as the factor to analyze the curriculum of Informatics subject and textbooks in middle school; these could be helpful to teach the ability of computational thinking in middle school. Results of these questionnaires show that the three steps and 13 learning contexts of computational thinking education are properly well-formulated. The 5 of 13 learning contexts, such as data collection, are missing in 2009 revised-Informatics curriculum in middle school as well as the seven Informatics textbooks that used in middle school contained 10 of 13 learning contexts for computational thinking education.

Society is operating with software and a new digital era through the Internet of Things started. A variety of fields are being in conjunction with each other based on computing. As problems in real life become more complicated and communication based on various knowledge and problem solving skills are emphasized, these changes are reflected in the curriculum. These changes started from overseas in advance then Korea includes SW education in elementary and secondary education through curriculum revision of 2015. On the other hand, SW education for university students just started after the curriculum revision of elementary and secondary education. The new SW education highlights and develops Computational Thinking beyond programming and it will be a key for the future. Therefore, this study analyzed trends of Computational Thinking and examples of CT courses in Universities. Suggestions and ideas for instructional model to develop Computational Thinking were discussed.

In order to cultivate talented people who have problem solving ability due to computational thinking according to the trend of the fourth industrial revolution, each university is actively promoting software education. This study suggests that understanding-oriented SW curriculum is needed for non-majors students to improve computational thinking. In order to achieve the purpose of the study, this study designed the basic education program based on the understanding of the SW with the backward design model. The SW Basic Education Program was applied to 15 weeks of instruction and conducted three surveys. The positive effects of the understanding-oriented SW basic education on the computational thinking efficacy and the computer perception were verified. In addition, it was found that the understanding-oriented computational thinking and programming education are effective when they are linked to one process. It is expected that understanding-based SW based education, which uses the backward design model, can be applied as one of the efficient ways to improve computational thinking in the education field.
