Because the success of SW education depends on teachers' competences and understanding, many universities of education are carrying out SW education for pre-service teachers. The purpose of this research is to analyze the current status of pre-service teachers' programming learning experiences and understanding of curriculum and educational effects related to SW education. The participants were 294 junior and senior students enrolled in a university of education. In relation to 'programming learning experiences', many responded positively in terms of interest, usefulness and willingness to learn. However, many were not satisfied with their programming experiences, felt difficulty in programming, and evaluated their programming abilities as low. For the 'understanding of SW education curriculum', many recognized the necessity of SW education and understood that the allocated time was insufficient. Both positive and negative opinions were reported concerning the fact that SW education is conducted in practical arts. In comparison, many did not understand well about the concept and characteristics of SW education and the details of the curriculum. In relation to the 'understanding of SW education effects', many understood positively about all the effects presented in the questionnaire including problem solving abilities and creativity. In addition, significant differences were found among pre-service teachers' major categories regarding the programming learning experiences and the understanding of SW education curriculum and effects. Based on the results of the research, suggestions were made for the improvement of the pre-service teachers' SW education program.

In this paper, We evaluated students' computational thinking in elementary school for SW education. Also, we analyzed on the difference of students' computational thinking according to the level of school's educational information. As a result, We confirmed that students' computational thinking were deferent according to the experience of schoolmaster's SW education and the ICT infra of school. In particular, students' computational thinking were meaningfully deferent according to the SW education experience of schoolmaster, the number of mobile devices for education and the speed of school network. Accordingly, we proposed the policy to heighten the effect of SW education. The policy were the extension of SW education for teacher, school network infra and mobile device for education.

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.

In the SW education of non-majors who encounter liberal arts education experience difficulties in the SW development environment and understanding they encounter for the first time, relevance to their major, and convergence thinking ability. In order to compensate for the difficulties of non-major learners in liberal arts education, a relatively easily accessible software was used to utilize a demonstration-oriented model that can be applied to beginners in SW education. In order to understand the logical flow of applications and problem solving used in real life, we proposed a convergence SW teaching method that combines repeated implementation through demonstration by the instructor and imitation of the learner, and learning indicators to increase the learning satisfaction and achievement of the learner. In the experiment applying the teaching and learning method proposed in this paper, meaningful results were shown when evaluating the learning effect, academic achievement, learning satisfaction, and teaching and learning method aspects of SW education.

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.

The purpose of this study is to explore non-major students' perception and experiences in college software education. For this, we analyzed the reflection journals of 36 non-major students in D University based on the Consensual Qualitative Research(CQR). As a result, there was not general core concept to all students nor a typical core concept that appeared to more than 50% students. However, various variable core concepts could be derived. Overall, 57 variable concepts were derived from experience in SW education and 7 variable concepts for perception of SW education. Based on this result, we found many of non-major students feel difficulty from unfamiliarity to SW education. Also, many students have satisfaction in their perception to SW education about personalized learning that their professor provided in the class. Lastly, we conclude that a methodology for SW education needs to have a careful operation strategy and interactive design. Although this study has not been able to elucidate general core concepts that appear to all learners, it has significant implication in terms of providing various implicit core concepts and suggestions for effective software education for non-major students.

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.
