SW which controls IoT devices using wireless communication technology must operate without errors. In order for IoT devices to be widely used, the technical skills of engineers who design such software must be improved. Compared to designing the input / output SW of a single device, the SW Flowchart design and Java SW programming process that clearly define various input / output relations between the transmitter and the receiver are complicated. In this paper, we proposed a SW Flowchart design method for controlling IoT devices based on wireless communication. In this process, it is explained that the entire control algorithm is implemented through a problem division process. In addition, we proposed an educational method for programming the designed SW Flowchart into Java SW using Microbits, which are educational IoT devices. In the course to which this education method was applied, the results of satisfaction evaluation of students were analyzed, and the effectiveness of the IoT device control SW education method using Microbits was analyzed.

Through the fourth industrial revolution and coronavirus pandemic situation, the necessity and importance of SW education are being emphasized more. However, it is difficult to achieve the effect of improving students' computational thinking skills by just 17th hour, which is organized in the 2015 revised curriculum. Moreover, due to the coronavirus pandemic situation that has continued since last year, there are environmental restrictions on the equal SW education for students at the educational site. In this study, the unplugged class using a completion robot was designed to reflect the current situation at the educational site and experience of SW education was provided to the 6th graders of J elementary school. Through the application of a class, we checked whether the unplugged class using robots affect students' perception of SW education and the use of computational thinking skills. As a result, the unplugged class using a completion robot showed that students used computational thinking to solve given problems and had a positive impact on changes in perception of SW education.

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 this paper, I developed a assesment indicator to evaluate SW program developed by students in SW education. The SW education carry out in elementary school, middle school and high school from 2016. But the assesment indicator to evaluate SW program had not been developed until now. Therefore, I tried to develop the assesment indicator that have harmoniously educational characteristic and SW qualitative characteristic. First of all, I had set the 15 attributes for assesment and developed the 36 criteria for 15 attributes. And the validity of 15 attributes and 36 criteria for assesment had been reviewed by 39 SW educational experts. As a result, the 15 attributes and 36 criteria for assesment were determined to which that have validity. I expect that the assesment indicator developed in this paper will raise the reliability of evaluation in SW education. And the assesment indicator may be used at SW competition conference for teenagers.

This study was conducted as a study on the SW career education of students from underprivileged areas, which is a necessary condition for SW education to become a universal education or where research has not been conducted. Therefore, this study conducted a SW career selection model using structural equations for 2,231 students in grades 3 to 6 in 6 schools located in the marginalized areas of eup/myeon. As a result of the study, it was analyzed that the intrinsic SW learning motive of students from underprivileged areas did not affect their SW career choice, whereas the external SW learning motive was analyzed to affect their SW career choice. This is inferred that the intrinsic SW learning motive does not affect the SW career choice due to the lack of SW experience of students in underprivileged areas. The correlation between internal and external SW learning motivation was analyzed to be significant. In the future, as students from the underprivileged class have more SW education experiences, research should be conducted on how internal SW learning motives affect SW career choice and how external SW learning motives support internal SW learning motives.

4차 산업혁명이 도래하여 사회 전반에서 혁신적인 변화가 일어났다. 이에 따라 2022 개정 교육과정에서는 미래 사회가 요구하는 소양 및 역량 강화를 위하여 인공지능(Artificial Intelligence, AI)·소프트웨어(Software, SW)교육을 비롯한 디지털 기초 소양을 강화하는 것을 개정의 중점으로 설정하였다. 이처럼 SW교육은 정보 관련 교과를 비롯한 타 교과에서도 중요하며 따라서 비 정보과 교사도 SW관련 교육 내용을 이해해야 할 필요가 있다. 본 연구에서는 비 정보과 교사에게 SW연수를 실시하였고, SW교육 수업 전문성의 변화를 살펴보았다. 그 결과 사전 검사에 비해 사후 검사 결과에서 통계적으로 유의한 상승을 확인하였다. 이는 SW연수가 비 정보과 교사의 SW교육 수업 전문성 함양에 긍정적인 영향을 준다는 것을 의미한다. 그러나 본 연구는 단일집단으로 이루어진 실험을 설계하여 실시하였으므로, 이러한 변화가 처치로 인한 것인지 확인할 수 없다는 한계점이 있다. 그러므로 통제 집단 및 실험 집단 선별 과정을 거친 후속 연구 설계가 요구된다.

SNS data was collected and analyzed by topic modeling techniques to examine recent trends in information education. By deriving keywords and topics for SW education and AI education, we not only attempted to discover insights ahead of the next revised curriculum but also suggested directions. According to the SNS data analysis, the contents of human resource development for software and the instructional method in schools are indicated as a high requirement. Meanwhile, SW education should be conducted through a separate curriculum from elementary school, and this was consistent with the opinion that it is necessary to be organized as a required subject. There was an opinion to support the schools since AI education is newly introduced in next revised national curriculum. The trends in SW education and AI education which are observed through SNS data analysis could be concluded to conduct the substantial operation of information education and curriculum organization.

The purpose of this study is to analyze the effect of SW education applying design thinking on the creativity of elementary school pre-service teachers. We conducted research on 22 elementary school pre-service teachers who applied for a lecture on elementary computer education at a university in Jeju city. The pre-service teachers who did not have basic understanding of SW education and basic knowledge about scratch program which is an EPL tool for research. Therefore, we had time to learn the basic education of SW education and the basic functions of the scratch program over 18 periods before the pre-test of creativity. After conducting pre-test of creativity and conducting SW education applying design thinking over 21 hours, we conducted post-test of creativity. As a creativity test tool, TTCT pattern test forms A and B of Torrance were used. As a result of the verification, it was found that SW education applying design thinking was effective in improving creativity of elementary school pre-service teachers.
