In the era of the Fourth Industrial Revolution, improving computational thinking to solve problems by smoothly operating and utilizing software. Therefore, the ministry of education has introduced systematic SW education into public education as a revised 2015 curriculum with the aim of raising computational thinking. In order for SW education to be systematically stabilized at the school site, the teaching ability of the teacher must be supported above all. For this purpose, the government is promoting 'SWEET' for improvement of the elementary pre-service teachers' SW education program. However, even if the policy is pursued, there is a tendency to take measures to improve the teaching and learning methods in the field later, and since the subject of change in education is the teacher, it is necessary to grasp the reco-gnition, experience of teachers. This study analyzed qualitatively perception and experience of elementary pre-service teachers about SW education and suggested design guidelines for pre-service teacher training such as providing various learning examples.

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.

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.

In the near future, as artificial intelligence and computing network technology develop, collaboration with artificial intelligence (AI) will become important. In an AI society, the ability to communicate and collaborate among people is an important element of talent. To do this, it is necessary to understand how artificial intelligence based on computer science works. An algorithmic education focused on problem solving and learning is efficient for computer science education. In this study, the results of an assessment of computational thinking at the beginning of the semester, a satisfaction survey at the end of the semester, and academic performance were compared and analyzed for 28 students who received algorithmic education focused on problem-solving learning. As a result of diagnosing students' computational thinking and problem-solving learning, teaching methods, lecture satisfaction, and other environmental factors, a correlation was found, and regression analysis confirmed that problem-solving learning had an effect on improving lecture satisfaction and computational thinking ability. For algorithmic education, if you pursue a problem-solving learning technique and a way to improve students' satisfaction, it will help students improve their problem-solving skills.

The purpose of this study is to investigate the effects of instructional strategies using the process of procedural thinking in elementary science classes on students' computational thinking and creative problem solving ability. For this purpose, instructional strategies using the process of procedural thinking for science class were developed and applied. The objects of this study were 6th graders from an experimental class (29 students) and a comparative class (29 students) at S elementary school in Gimpo City. The results of the study are as follows: First, as a result of examining the difference in the computational thinking ability between experimental group and comparative group, the experimental group scored higher than the comparative group, but there was no statistically significant difference. Second, the creative problem solving ability of the experimental group after applying this program was higher, and statistically significant differences were observed (p < .05).

2015 개정 교육과정에서는 컴퓨팅 사고력을 핵심 역량 중 하나로 설정하였으며 역량 함양을 위해 문제해결과 프로그래밍, 컴퓨팅 시스템영역에서 각각 프로그래밍 교육과 피지컬 컴퓨팅을 편성하였다. 또한 선행연구를 통해 효과성을 알 수 있었지만 연구의 편차로 인해 피지컬 컴퓨팅이 가지는 교육적 효과크기에 대한 검증의 필요성이 제기되나 관련연구가 진행되지 않았다. 따라서 본 연구에서는 피지컬 컴퓨팅의 동향 및 효과 분석 연구의 부분으로 피지컬 컴퓨팅 도구 및 프로그래밍 언어의 활용 동향을 분석하고자 한다.

이 연구는 초등 교사를 대상으로 한 효율적인 연수 프로그램 구성의 출발점 자료를 확보하고자, 초등 교사 200명을 대상으로 SW 교육 영역(SW 문화, SW 창의, SW활용)의 소양 정도를 파악하고 영역 간의 관계를 분석하였다. 연구의 결과, SW 문화소양의 충족, 특히 SW 윤리 소양의 충족이 SW 창의교육 영역(컴퓨팅 사고력과 SW 제작 소양)에 큰 기여를 하는 것으로 확인되었다. 따라서 SW 교사 연수 효율성 제고를 위해 SW 윤리 영역이 컴퓨팅 사고력 영역 및 SW 제작 영역에 관한 교육 내용과 연계성 있는 배치와 시간 운영이 필요하겠다.

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 attempted to examine the effects of SW education using EPL and coding robots on computing thinking and problem-solving skills among various teaching and learning methods of software education. To this end, a survey was conducted on 350 students from middle schools A and B in Gwangju and Jeollanam-do, and the difference in mean was analyzed through t-verification and one-way analysis of variance in order to investigate the relationship between variables. Based on the research results obtained through this, we will identify the effects, strengths, and weaknesses of SW education using EPL and coding robots, provide basic data and information for efficient teaching and learning methods of SW education, and further suggest better directions in terms of academic and practical aspects.
