In this study, we conduct SW education using robot in elementary school, to examine the effects of SW education using robot on CT and gender differences. In order to achieve the purpose of this study, SW education using robot was conducted to 143 students in 5, 6 grade in GyeongGi. After collecting data, we examined mean difference using matched pair t-test and ANCOVA. The results of this study were as follows: The SW education using robot is associated with significant improvements in CT, however, computational concepts is not associated with significant improvement in high initial score sub sample. And CT is not associated with gender. This study was investigated effects of the SW education using robot and identify gender differences. And expanded the understanding of the SW education using robot.

In the previous study on the effectiveness of SW education, the educational goals were mainly focused on developing computational thinking ability and researching changes in computational thinking ability. But the word "computational thinking" is difficult to the public. Also the definition of computational thinking is varies from scholar to scholar. Therefore, this study aims to inform the public of the excellence and effectiveness of SW education through the change of "writing ability" which is more familiar to us. To achieve this goal, 10 lectures of SW training materials were produced and conducted in elementary science gifted class. As a result, significant changes have been made in the fluency and quality of writing skills, proving that SW training improves students' writing skills. Through this, we confirmed the visible results through SW education, which can be called justification of SW education. Furthermore, it is expected that various educational attempts will be developed using SW in other subjects.

본 논문은 매우 크고 복잡한 실시간 소프트웨어(SW)의 성질들을 이해하기 위한 방법론을 제시한다. 실시간 SW는 일반적으로 상호작용이 많은 프로세스들을 대량으로 가진 수십만에서 수백만 줄의 코드로 구성되어 있다. 이런 SW는 일반적으로 이해하기가 매우 어렵다. 이런 문제를 해결하기 위하여 본 논문에서는 SW를 체계적으로 이해하기 위한 scalable하고 modular한 접근 방법으로서 architecture에 기반을 둔 SW understanding model, 즉 SUMarchitecture을 제시한다. 이 모델은 SW로부터 architecture를 추출하여 SW를 상하계층적 구조로 구성하고 이 architecture의 복잡계층축을 토대로 SW의 구조, 기능 행위의 3차원적인 정보를 추상화 단계와 상세 단계에서 이해할 수 있게 한다. 즉, 이 모델은 복잡계층성, 구조성, 기능성, 행위성, 명세-상세 이원성 등의 5차원 세계에 토대를 둔 SW 역공학 종합 모델이다.

본 연구는 SW교육 기초연수를 수강하는 SW교육 초급교사의 SW교육 교수효능감을 측정하고, 그 현황을 파악하여 이를 바탕으로 수강자의 SW교육 교수효능감을 신장시킬 수 있는 연수를 기획 및 수행하는 기초자료를 마련하고자 수행되었다. 연구 결과 SW교육 기초연수에 참가한 교사의 SW교육 교수효능감 중에서 교사 자신의 교수능력에 대한 개인적 판단인 개인효능 영역에서 연령, SW교육 경험에 따라 큰 차이가 존재함을 확인할 수 있었다. 따라서 SW교육 기초연수에서 5년 미만의 저경력 또는 20년 이상의 고경력 교사와 SW교육 경험이 전혀 없는 교사의 개인효능을 향상할 수 있는 방법을 고민하고 이를 연수에 반영할 필요가 있다는 시사점을 도출하였다.

The purpose of this study is to find out the perception of parents in order to develop a software education program for elementary students convergence with English. A survey was administered to 120 parents asking perceptions about SW education in schools and preferences about English-SW convergence programs for their elementary school children. The results shows that the parents think the current 17 hours of SW education provided at elementary schools is not enough and also they hoped the education started at an earlier grade than the current 5th·6th graders. Most parents perceived English is helpful in SW education and answered strongly for the need of English-SW convergence programs. A two-week program with the ratio of 6(SW):4(English) was the most preferred according to the study. As for regional differences, the parents in Seoul and Gyeonggi Province wanted SW education as after-school programs in elementary schools whereas, parents in Chungcheong Province expected SW education programs be provided from near-by universities. It is hoped that with the results of this study various English-SW education programs are developed and operated.

The purpose of this study is to examine the effects of SW education using robots on Computational Thinking, Creativity, Academic Interest and Collaborative skill. In order to achieve the purpose, SW education using robots was conducted to 88 students in 5th grade in Seoul. After collecting data, we examined mean differences using matched pair t-test. The results indicated that the SW education using robots is associated with significant improvements in Computational Thinking, Creativity and Academic Interest while Collaborative skill is not associated with significant improvement. This research investigated the effects of the SW education using robots and expanded the understanding of the SW education using robots. In addition, this study provides several implications with regard to suggesting the direction to go further of SW education using robots.

LVC-G COTS SW are widely used for the military training due to several advantages. Accordingly, LVC-G COTS SW domestic developments are in demand. In this study, there are the four hypotheses in the gap between users and developers and establish the hypotheses are all correct. The first hypothesis "LVC-G associated with the COTS SW between users and developers about the requirements for the performance gap is expected.", the second hypothesis, "LVC-G associated with between users and developers for COTS SW technology gap is expected for the elements. ", the third hypothesis" LVC-G associated with the COTS SW development costs between users and developers about the expectations gap is about. ", the fourth hypothesis" LVC for COTS SW-G and related skill levels between users and developers are excited about the gap ". Every hypothesis were confirmed to be valid by interview and survey.

The purpose of this study is to statistically analyze the correlation between unplugged activities using SW educational board games and computational thinking ability of elementary school students, and then find a method of SW education through the results. The study was conducted with 40 students in the 5th grade at an Elementary School in Incheon. Students participated at unplugged activities using a board game for SW education with 12 hours of teacher guidance and 10 hours of free activities. After that, a post-test was conducted to analyze the degree of improvement in computational thinking ability. As the results, it was confirmed that the comprehensive computational thinking ability was improved, and that the four areas of the sub-domains of computational thinking ability were improved to a significant level. These results suggest that providing a basic SW education experience by utilizing a board game for SW education helps to improve students' computational thinking ability.
