Although software education pursues developing learners' computational thinking skills, more studies are needed in terms of designing software education lessons to enhance CT skills and to measure the effects of the lessons. This study aims to investigate the effects of a course designed to enhance pre-service teachers' CT skills by using CT-based teaching materials. Through a literature review the study has selected the five core competencies of CT: algorithmic thinking, evaluation, problem decompositions, abstraction, and generalization. The participants of the study are 47 pre-service teachers who took the one-semester course in a national university of education. A survey was developed and conducted and qualitative analyses on the team projects were performed focusing on the core competencies of CT. The results revealed pre-service teachers' perceived degree of experiencing CT and their competencies represented in their projects. The present study provides important implications to future software education programs in terms of designing and implementing of software education.

이 연구의 목적은 기존 CT 검사 도구를 확인하여 한계를 파악하고, CT 기반 역량의 의미를 밝히고 이를 통해 올바른 CT 검사도구 개발의 방향을 제시하는 것이다. 그래서 이 연구로 CT 기반 스킬을 통해 CT 역량을 검사할 수 있는 방법을 제시하였다. 이 연구의 결론으로 CT 역량을 검사하는 것은 CT 기반 역량을 검사하는 것으로 CT 기반 하드스킬을 밝혀내어 이를 평가 요소로 적용한다면, 기존 검사도구의 한계를 극복하는 묘책이 될 것으로 판단되었다. 이 연구의 후속으로 CT 기반의 하드 스킬을 찾아 CT 기반 역량을 명확히 규명하고, 이를 바탕으로 검사도구를 개발하여 검증하고자 한다.

As computational thinking(CT) is gaining focus as a key 21st century skill much attention has been paid to promoting CT through software education. However, more studies are needed to design and implement effective CT assessment methods. This study aims to investigate the effects of three CT assessment methods in a course designed to enhance CT competencies of 52 pre-service teachers with a non-computer science background during one semester. To analyze pre-service teachers' CT competencies, we used 3 CT assessment methods: (1) pre-and post-testing based on Bebras computational thinking challenge questions, (2) Dr. Scratch to analyze group scratch projects automatically, and (3) scratch exam designed in this study to evaluate the development of CT. Our results show the positive effects of integrating assessment methods for promoting CT competencies. We end this paper with the discussion of advantages and implications of this integration.

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.

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.

Due to increase in software-based new technologies, software developers are being required to creative problem solving. Especially, for a successful business change of software developers into a new industrial field, software analysis phase and design phase are important and it is an important task to strengthen these competences. In this study, two independent researches were conducted. First, a survey with 300 software developers was conducted and it was explored that uniform thinking of software developers caused by application of "standard software development methodology" made it difficult to approach creative problem solving. Based on this finding, the influences of 9 competences of computational thinking on software developers were analyzed after selecting 111 software developers with over 10 years of experience in the IT industry. As a result, it was revealed that abstraction was an important competence. The study finding demonstrates that software developers recognized design phase as the most important thing and abstraction of CT is the basics of other competences.

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.

It is urgent in the context of the Fourth Industrial Revolution that students become creative and integrative thinkers. In this vein, in the last few years, drawing upon constructivism as an innovative learning paradigm, new coding curricula using MIT's Scratch have been introduced in the number of countries to enhance computational thinking (CT). However, constructivism encouraging collaborative and active learning may not be explicitly utilized in instructional design focusing mainly on learning to code as technical skills - some of which exist today in large numbers of school and after-school code activities. To respond to such a misleading way of developing CT through coding, the present study aims to propose the benefits of CT self-assessment rubrics for primary pre-service teachers within a CT course entitled "Problem Solving by Computational Thinking". Our findings show how meaningful collaborative CT self-assessment in a group impacts their learning of CT. We end this paper with the discussion of implications of our findings for CT assessment towards a new paradigm in education.
