Software courses required for all students regardless of their major in many universities. SW educational effectiveness model needs to be developed to enable effective communication among students, professors, and SW educators, and to identify the responsibilities of SW educators. SW educational effectiveness model based on literature review is composed of computational thinking, SW literacy, SW awareness, and SW attitude. Computational thinking, focused on analysis and design of problem solving processes, consists of decomposition, pattern recognition, abstraction, and algorithms. SW literacy involves viewing social development based on SW beyond information literacy in the digital age. The SW awareness and attitude were organized by considering the collegiate contexts. The SW educational effectiveness model will be used as the basis for diagnosis tools as further studies.

The purpose of this study is to compare and analyze the effects of physical manipulative and exploratory geometry software on the spatial sense for 5^th grade elementary school students in learning nets. For this purpose, ton experimental group used Geofix, an operational learning tool, and the experimental group used Cabri 3D, an exploratory geometry software to learn the nets of solids. The comparison group was learned by worksheet only without any manipulative or software. Spatial sense tests were conducted before and after to determine the level, and eye tracking were used to analyze the strategies of students in solving nets problems. As a result, it was confirmed that the using Geofix group was the most effective for the spatial sense, and Cabri 3D could also be a good tool for learning the nets of solids. In addition, after learning the nets of solids, the analytical strategy, which was the most effective strategy for students' solving strategies, increased. In the process of solving spatial tasks such as the spatial sense tasks, eye tracking technology become a very useful tool for exploring students' strategies, so it is expected that objective and useful data will be collected through more active use in the future.

Lately, as the importance of software and the software education has been emphasized, the studies on ways of teaching programming to elementary students have been actively progressed. However, most of undergraduates as prospective elementary teachers who will be in charge of teaching programming at the elementary schools have a lack of interest in programming education as well as of the understanding of basic programming principles. Therefore, this study investigated how programming education using hands-on robot and scratch affected learning motivation and academic achievement of preliminary teachers. The comparison of results of two programming educations shows that the programming education using hands-on robot revealed statistically significant difference in learning motivation and academic achievement.

A variety of educational policies have been implemented to educate outstanding individuals who will lead the future and to adopt supporting systems. For the successful implementation of educational policies, it is crucial to identify the perception of teachers as main agents of education. This study conducted a survey with elementary teachers in Chungcheongbuk-do. The purpose of this study was to investigate teachers' perception on the major policies related to ICT(i.e., STEAM, Smart Education, Software Education, e-textbook, and EdudataSystem). This study also compared the distribution of teachers' perception on the policies. The results of the study indicated that teachers had relatively positive perception on the importance and the necessity of the policies. On the other hand, it was found that the levels of teachers' training experiences and readiness for teaching related to ICT were relatively low. In addition, the patterns of teachers' perception on STEAM, Smart Education and Software Education were similar. Based on the results, the study suggested that appropriate support and educational strategies for effective implementation of policies should be established.

In elementary school software education, a programming process is experienced through a simple problem solving process. And even this experience emphasizes that the problem-solving process is a CS Unplugged activity. However, CS Unplugged has a disadvantage in that it only learns the principles of computing, and the learner cannot experience real problem solving. In this study, a learning program using artificial intelligence robots was developed with the goal of cultivating the ability to solve problems encountered in the real life of elementary school students. Students could solve complex problems in real life from the point of view of artificial intelligence through the developed program, and increase their interest and understanding of artificial intelligence education through robot control.

In the 2022 revised curriculum general study released by the Ministry of Education in September 2021, environmental issues are emerging as a socially important topic, with climate and environmental education appearing at the forefront along with software education. In this study, by applying Python Monte Carlo simulation, a program for high school students was developed that combines environmental education and software education emphasized in the 2022 revised curriculum. The developed program verified the validity of the program with Lawshe's Content Validity Ratio for science, environment, and information subject education experts, and the verification results showed that the program meets the development purpose, environment, and information subject achievement standards.

According to the 2015 revised curriculum, the software education was provided to elementary school education in Korea. In Korea, information education became a necessary education. However, in Korea elementary school, information education is still not operated as an independent subject. This study examines the information education curriculum and information education textbook contents at the national level of Korea and China. The implications of this study can help establish the direction of information education in Korea.

This study firstly examined 18 prospective secondary mathematics teachers' understanding of the nature of definitions and the use of the dynamic geometry software Sketchpad to not only improve their understanding of definitions, but also their ability to define geometric concepts themselves. Results indicated that the evaluation of definitions by accurate construction and measurement enabled students to achieve a better understanding of necessary and sufficient conditions, as well as the ability to more readily find counter-examples, and to recognize uneconomical definitions, and improve them.
