This study aims to apply a teaching-learning model using science oriented UCC created by students themselves(4C model) in a gifted students' project learning and investigate its effects in science-related affective property by gender in order to use UCC systematically in a gifted students' project learning course. After conducting of gifted students' using UCC project learning, We surveyed gifted students' recognition about it. Nonparametric test has done with the results of before and after science-related affective property tests of them. As results, gifted students took an active part in 'using UCC project learning'. Girls are more active and interested than boys whereas more boys felt a difficulty in creating UCC than girls. Girls' creativity was improved and anxiety about science was decreased whereas the results of boys were not statistically significant. Therefore, 'using UCC project learning' is more effective than tha of boys to girls.

This study investigated the definition and characteristics of computer science problem to be solved through computational thinking. It also explored types and cases of both computer science problems and teaching learning methods to solve computer science problems. Before studying computer science problems, I examined the definition, type, and the importance of problem solving in other subjects. Based on this research, We found that informatics can solve ill-structured problems through computational thinking and the power of computing. This includes counting, decision, retrieval, and optimization problems. Teachers can improve their students' skills in computational thinking, particularly as related to abstraction, automation, and generalization, by choosing the appropriate teaching and learning method or based on the characteristics of the problem.

The purpose of this study was to analyze STEAM learning/teaching program that relates robots and to develop and redesign STEAM teaching/learning program with a robot for elementary and secondary schools. 'Learning with a robot' is considered as one of the best candidates for STEAM education. This article mainly concerns a robot that can be helpful to improve students' interests in learning science and mathematics in schools. As the results of the STEAM learning/teaching program analyzing, the program for elementary schools contained more contents of liberal arts and fine arts, and the program for secondary schools contained more contents of science, technology, and math. In the middle school program, context for learning, class activities of creative design and emotional touch, evaluation, and job and career information were evenly implemented. In the elementary and high school program, there were few information about robotics career. We extracted all robot utilizable subjects and units from school curriculums, and redesigned contents which can be applicable to regular classes for schools. As the result of this study, we conclude that 'learning with a robot' can encourage students' interests in STEM area.

The recent advances of the information technology have motivated lots of research efforts to develop new computer-aided teaching and learning methodologies on various computer science topics, such as data structures, operating system, computer networks, and computer architecture. However, there have been only few studies to educate the database subject although it is one of the most important topics in the computer science. Specifically, among the various issues in the database subject, a learner often suffers to understand the mechanism of the concurrency control and recovery of database transaction in the database because it highly interacts with other functions in the database. Obviously, an intelligent visualization tool can help a learner to understand the process of the concurrency control and the recovery of database transaction. The purpose of this study is to develop an efficient visualization tool which can help users understand the two phase locking protocol (2PLP)-based concurrency control. Specifically, this visualization tool is designed to encourage a users' participation and raise their interest by visualizing the process of transactions and allowing users to specify and manipulate their own transactions.

The purpose of this study is to extract the factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction and analyze the structural associations between them. Factors that compose the image of science teacher desired by elementary school students in inquiry-based instruction were extracted through exploratory factor analysis (EFA). Based on the findings of EFA, the questionnaire has been further analyzed using confirmatory factor analysis (CFA). In addition, based on the factor structure identified through factor analysis, we comprehensively analyzed the image of science teacher desired by elementary school students in inquiry-based instruction. As a result of EFA, five factors were identified which compose the image of science teacher desired by elementary school students in inquiry-based instruction: namely, teaching strategy, assessment strategy, prior guidance, understanding students, learning development. The CFA results showed a relatively strong correlation between teaching strategy and learning development, teaching strategy and understanding students. As a result of a comprehensive review of students' perception of the image of science teachers in inquiry-based instruction based on the extracted factor structure, students perceived that it is important for science teachers to run inquiry-based instruction by reflecting their understanding of students. Students also perceived importantly that science teachers run inquiry-based instruction using effective teaching strategies and proper evaluation strategies.

In order to suggest instructional strategy and learning guidance in science education, the purpose of this study was to classify middle school students by learning style and then examine student's science process skills via those learning styles. The Student Learning Style Questionnaire (SLSQ) and the Test of Science Process Skills (TSPS) were given to 340 ninth graders. Their learning styles were classified into three categories, that were divided into two opposing types: independent/ dependent, collaborative/ competitive, and participant/ avoidant. The results showed the following : 1) Students of the dependent, collaborative, and participant type out numbered ones of the independent, competitive, and avoidant type. 2) Gender differences showed that male students of the competitive, participant, dominant type totalled more than the female students of the collaborative, avoidant type. Furthermore, 3) For students of the independent, competitive, participant type, science process skills were higher than those of the dependent, collaborative, avoidant type.

Archival contents service for education is now a major service program in a foreign National Archives. Therefore We need to study their archival contents services in more depth-analysis methods for the development of our contents. My study is based on the summary of the Homepage Sites for Education of the TNA of UK and the NARA of USA. And also a depth-case study on structures of the samples, 'Coldwar' contents of the TNA and the 'McCarthy' contents of the NARA. As a results, first, the formats of archival contents for teaching-learning materials should be in consistent contents structures like a standard textbooks. Second, archival contents service for teaching-learning materials certainly have to support original images of primary resources and educational kits in order to read easily primary sources. Third, given the costs of development, it's desirable for archive to develop archival contents for teaching-learning materials in the way of cross-use by age and curriculum. Forth, when selecting primary sources for teaching-learning materials, priorities have to be given to the text-sources in the light of learning purposes for history education. Fifth, National archives must develop archival contents for teaching-learning materials in connection with standard curriculums in order to promote a nation-wide use.

The wave of a knowledge and information society led by AI, Big Data, and so on is having an all-round impact on our way of life. Therefore the Ministry of Education is in a hurry to strengthen Digital Literacy, including AI and SW Education, by improving the curriculum that can cultivate basic knowledge and capabilities to respond to changes in the future society. It can be seen that establishing a foundation for cultivating Digital Literacy through all subjects and improving basic and in-depth learning in new technology fields such as AI linked to the information curriculum is an essential part for future society. However, research on each content for cultivating Digital and AI literacy is relatively active, while research on teaching and learning strategies is insufficient. Therefore in this study, a CT-based Digital and AI teaching and learning strategy that can foster that was developed and Delphi expert verification was conducted, and the final teaching and learning strategy was completed after evaluating instructor usability and analyzing learner effectiveness.
