This study was to review the research trends in domestic computing thinking and to suggest future research direction by analyzing 138 papers related to computing thinking published in domestic academic journals from 2015 to 2018. As a result, domestic research on computing thinking has been steadily increasing since 2015, and quantitative research, development research and experimental research were mainly used. Most research were conducted for elementary school students and university students. Research topics are oriented to the curriculum and program as well as the relationship among the variables related with computational thinking. It is necessary to explore empirical studies such as teaching methods, teaching tools, media utilization, and evaluation methods in order to promote learner's computing thinking. Also, it is needed to explore various variables related to enhance computing thinking and the relationship among the variables.

The purpose of this paper is to analyze the elementary school students' level of computational thinking ability by analyzing the domestic question and examination results of Beaver Challenge 2017. Based on the results of the 'Challenge' results of Beaver Challenge 2017, the achievement by element, gender, and grade of elementary school students II (elementary school 3.4) and group III (elementary school 5.6) Respectively. As a result of the analysis, the achievement by the evaluation factors showed difference within each group. In addition, there was no significant difference in achievement according to gender except for one area of group II. The achievement level of each grade was statistically significant in the group III. The results of this study are expected to provide implications for the level of students related to what can be evaluated in elementary school information education and contribute to the follow-up research.

일반 학생과 소외계층 학생은 컴퓨팅 기기에 대한 접근성은 큰 차이가 존재하지 않지만, 컴퓨팅 기기를 활용하는 역량에서는 큰 차이가 존재한다. 이러한 문제는 소외계층과 일반 학생 사이에 컴퓨팅 사고력 차이를 유발하였으며, 공교육에서 이루어지는 소프트웨어 교육의 효과 차이를 초래하였다. 이러한 문제를 해결하기 위하여 본 연구에서는 소외계층의 컴퓨팅 사고력을 분석하는 연구를 진행하였다. 소외계층 학생을 대상으로 설문 조사를 진행하고, 설문 결과를 요인에 따라 분석하는 연구를 진행하였다. 연구 결과, 소외계층 학생은 학교급이나 성별에 따른 컴퓨팅 사고력의 차이는 존재하지 않았다. 반면에 경험한 프로그래밍 언어에 따른 컴퓨팅 사고력의 차이가 나타났다. 특히, 소외계층 학생은 프로그래밍 언어 경험이 많을수록 컴퓨팅 사고력이 높은 것을 확인할 수 있었다.

The purpose of this study is to verify the effect of the design - oriented model (NDIS) for enhancing learner's computing thinking in SW education. NDIS is a project-based learning model in which learners find real-life problems, analyze their needs, and design and implement them. In order to verify the effectiveness of NDIS, we experimented with middle level G education university students who had previously experienced SW education class. The traditional project model was applied to the control group and the NDIS model based on CT was applied to the experimental group. The experimental group showed a higher CT narrative performance evaluation score than the comparative group, which showed a significant difference. In addition, students showed a positive perception of self-confidence and CT improvement in solving real-life problems using computing.

In this paper, we propose to discover the certification items and to study the content system for SW education instructors, including SW education based on basic teaching-learning capabilities and Computational Thinking(CT). To this end, SW education instructor qualification were divided into three classes using methods such as prior case studies, Delphi surveys, and expert meetings, and the certification evaluation areas were divided into large areas of 'Teaching and Learning Method' and 'Software Education' reflecting primary and secondary curriculum. Sub-areas and content elements for each series were set and verified through expert Delphi survey. Such research is expected to contribute to the spread and dissemination of SW education by being used meaningfully when establishing a system that fosters SW education instructors and maintains and manages the quality of instructors.

In the Fourth Industrial Revolution, a super-intelligent and super-connected society has arrived. Software is an important part of the core technologies of the Fourth Industrial Revolution. The ability to solve problems through software requires software education in that it is a core competency that everyone should have. Software education aims to improve Computational Thinking, which is the ability to solve problems through programming. Until now, most problem-solving programming learning models follow the traditional method of development: Waterfall model (Analysis-Design-Development-Test). In this model, if there is a problem in the preceding step, That could be found in the test phase. This takes a considerable amount of time and effort to find a solution to the problem and can be a burden on the programming learning. In this study, we proposed a Test-Driven Problem-Solving learning model using TDD (Test Driven Development) as Agile development method, and reviewed the appropriateness of the model through experts review. The verification results of the model showed positive evaluation results. In particular, the learning phase configuration of the model, helping in programming learning, helping of Computational Thinking improvement showed high rating, it is determined that there will be positive effects on Computational Thinking improvement through problem-solving programming learning when applying future learning.

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.

As creativity and problem-solving ability become core competencies, the main objectives of programming subjects in the elementary and secondary educational curriculum is 'computational thinking'. This goal can not be achieved at the level of understanding the characteristics of the programming language and the simple utilization abilities of the computer. The abilities to write algorithms and solve problems in real life situations using programming languages are required. In order to cultivate these abilities, the curriculum of the programming area was strengthened in the elementary and middle education curriculum, and the criteria for evaluating the achievement level were also prepared. However, the curriculum that can be used in actual education field is not yet established. In this study, we analyzed the researches on the existing programming curriculum and evaluated how well the curriculum meets the achievement criteria. Also, we can suggest the aspects to be considered in the study of programming curriculum and to verify whether the results of curriculum operation are in line with achievement criteria. In addition, future directions in elementary and middle school programming curriculum are suggested.

As SW education has become essential since 2018 due to the revised curriculum in 2015, researches on SW education are actively being carried out. In order to understand the level of pre-service teachers' computational thinking level, we analyzed a correlation of CT element scores with each year and each grade based on the calculated Scratch project by years using the analysis tool Dr. Scratch, which was targeted for 325 students in K National University of Education who passed the scratch course from 2016 to 2018. The result indicated that there is a positive correlation between all the CT related factors and both the year and the grade. Conclusionally, it is crucial to have students undergo revising process by using an automated evaluation tool such as Dr. Scratch and cultivate ability to create and utilize required materials. Furthermore, it is necessary to educate students to utilize logical thinking elements such as complex conditions and logic operations.
