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.

The evaluation of programs related to SW development often only provides the right answer of the student's program. The purpose of this study was to provide the baseline data about the contents of the program evaluation support the teacher's class and which part should be considered important in partial scoring. To accomplish the goal, we had two months of Python lessons for 90 middle school students in free-semester and analyzed 1185 source codes collected during the lessons. Result of analysis, many students made mistakes about syntax errors and teachers considered logic errors as important. Based on the result, it is necessary to reduce the student's syntax errors and teachers need to evaluate student's program with considering the importance of logical aspects and necessary to devise a partial scoring. This study has significance about consideration of program evaluation from the perspective of learning support and evaluation.

스크래치박스를 이용한 임베디드 응용 소프트웨어 통합개발환경은 응용 프로그램 개발자들에게 타겟종류에 관계없이 일관된 개발 환경을 제공하는 것을 목적으로 하고 있다. 응용 프로그램 개발자들은 개발하고자하는 응용 프로그램의 실행환경(타겟)에 따라 개발 및 실행 환경 구축에 많은 시간을 소비한다. 따라서 이러한 개발 및 실행 환경 구축을 용이하게 해주는 통합개발환경을 응용 프로그램 개발자들에게 제공함으로써 응용 프로그램 개발 기간을 단축시킬 수 있다. 또한 다양한 실행 환경을 제공함으로써 응용 프로그램 개발자들이 자신이 개발한 응용 프로그램을 적절히 테스트 해 볼 수도 있다.

The researches on the concept of justice and utilization for Computational Thinking with SW education are being actively discussed. However, a program has developed in conjunction with the actual elementary curriculum is not much. In this study, we have developed an educational program in applied mathematics based on CT. First, a separated view for a CT Application of mathematical concepts and objectives are set in three different application models. In order to achieve the CT-based math lessons, we also have developed a teaching and learning materials. We applied the developed materials in class, and to evaluate the satisfaction of learners. In addition to the validation of school application, we conducted a survey of professionals and teachers. The results of the analysis, the data showed that are helpful in the development of the student' CT ability as well as the ability to be helpful teaching and learning in school.

The goal of this study is to introduce the SW Edu-thon program designed to strengthen pre-service teachers' software teaching competencies and to report its outcomes. In order to achieve the goal, we have conducted a survey for twenty-two teams of two pre-service teachers who have participated in the regional pre-contest and selected for the best lesson plans. The survey consists of several sections including the level of SW competencies, learning motivations, educational outcomes, satisfaction toward the lecturers, mentors, educational programs, and management and operations. In addition, we have analyzed the mentors' progression reports written by the participating in-service teachers who have helped the pre-service teachers to develop and implement their SW lesson plans. The results of this study provide with the outcomes of the program and the future directions for operating the SW Edu-thon program.

The purpose of this study was to develop a stuttering therapy device to aid in stutter therapy. The research method used for this study was as follows: First, the stuttering therapy device based on analysis of the prolonged speech method used at home and abroad was designed to achieve the goal of research. Second, the stuttering therapy device was to be developed to maintain a vocalization state, to use bio-feedback visualization, to have enough inspiration, to use Korean language in this device, and to use transfer and maintenance training in daily life. Third, the stuttering therapy device effectiveness was to be verified through use in clinical cases. The results of subjects receiving speech therapy and using the breathing control prolonged speech device and SI(stuttering Interview) evaluation programs for 3 months were as follows: For subject A, the stuttered word rate was reduced from 3.20 SW/M to 0.5 SW/M. For subject B, the stuttered word rate was reduced from 1.90 SW/M to 0.75 SW/M. For subject C, the stuttered word rate was reduced from 3.37 SW/M to 0.34 SW/M. For Subject D, the stuttered word rate was reduced from 0.51 SW/M to 0 SW/M. Follow-up evaluations verified the effectiveness of how the stuttering therapy device can reduce subjects' SW/M.

In this paper, to find out the direction of interest related to the SW education, SW education news data were gathered and its contents were analyzed. The topic analysis of SW education news was performed by collecting the data of July 23, 2013 to October 19, 2015. By analyzing the relationship among the most mentioned top 20 words with the web crawling using R, the result indicated that the 20 words are the closely relevant data as the thickness of the node size of the 20 words was balancing each other in the co-occurrence matrix graph focusing on the 'SW education' word. Moreover, our analysis revealed that the data were mainly composed of the topics about SW talent, SW support Program, SW educational mandate, SW camp, SW industry and the job creation. This could be used for big data analysis to find out the thoughts and interests of such people in the SW education.
