Computer and Information Literacy(CIL) is one of Key Competences in 21st century. Many countries, including Korea, have adopted related contents in their national curriculum for conducting software education. With this movement, many book-type instruction materials for software education have been developed in Korea. However, it is scarce to find researches that evaluate the instruction materials from the perspective of CIL. In this study, we selected 4 instruction materials which were distributed by government with 'SW centered society' web site as well as were developed to teach physical computing for elementary students. Also, we analyzed if they can foster students' CIL. First of all, the evaluation framework was developed based on 'The Manual for Authorized and Approved Textbook' and 'The 2018 ICILS(International Computer and Information Literacy Study) Assessment Framework'. Then, 12 school teachers who have professional insight of software education evaluated the 4 instruction materials with the framework. Averaging the score given by evaluators, we determined that which instruction materials were superior or not. Finally, we figured out the characteristics of superior and inferior instructional materials. Based on the results of this study, we suggested implications for developing instruction materials for physical computing education to build students' CIL.

Across the world, there is a movement to incorporate computational thinking(CT) into school curricula, and math is at the heart of this movement. This paper reviewed the meanings of CT based on the point of view of Jeanette Wing, and the trend of domestic and international studies that incorporated CT into the field of mathematics education was analyzed to provide implications for mathematics education and future research. Results indicated that the meaning of CT, defined by mainly computer educators, varied in their operationalization of CT. Although CT and mathematical thinking generally have common points that are oriented toward problem solving, there were differences in the way of abstraction that is central to the two thinking processes. The experimental studies on CT in the field of mathematics education focused mainly on the development of students' cognitive capacities and affective domains through programming(coding). Furthermore, the previous studies were mainly conducted on students in school, and the studies conducted in the context of higher education, including pre-service and in-service teachers, were insufficient. Implications for mathematics teacher educators and teacher education as well as the relationship between CT and mathematical thinking are discussed.

Purpose This study explores the development direction of the artificial intelligence curriculum as a universal education that enhances the ability of college students to flexibly use artificial intelligence these days, where artificial intelligence education is spreading, and the educational components based on this are subdivided according to the characteristics of each major. Design/methodology/approach In order to develop the educational purpose of the subject and the detailed educational curriculum suitable for the subject of education, we first analyzed domestic and foreign prior research related to artificial intelligence liberal arts education. As the main components derived by experts, the basic concept of artificial intelligence converges to literacy to read and write for everyday problem solving, as well as problem-solving ability to manipulate real data and software. Findings The results showed that In the artificial intelligence literacy module, trends and prospects of artificial intelligence and necessary competencies were checked, and cases applied to major fields were examined. In the AI utilization and application part, basic data analysis items and content composition were composed through creative thinking, logical thinking, and intelligence. In order to design the curriculum, a software development language suitable for each major area was first selected, and AI education content areas, elements, and packages were defined and designed for each major area to meet the objectives of the subject.

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.

As the online education market expands, educational contents with various presentation methods are being developed and released. In addition, it is imperative to develop content that reflects the usability and user environment of users who use this educational content. However, for qualitative growth of contents that will support quantitative expansion of markets, existing model analysis methods are urgently needed at a time when development direction of newly developed contents is secured. In this process of content development, a typical model for setting development goals is needed, as the rules of the prototype affect the entire development process and the final development outcome. It can also provide a positive benefit that screens the issue of performance dualization between processes due to the absence of communication between a single entity or between a number of entities. In the case of AR-based educational content which is effective to secure data necessary for development by securing samples of similar categories because there are not enough ready-made samples released. Therefore, a big data statistical analysis service is needed that can easily collect data and make decisions using big data. In this paper, we would like to design analysis services that enable the selection and detection of intuitive multidimensional factors and attributes, and propose big data-based statistical analysis services that can assist cooperative activities within an organization or among many companies.

The objective of this research is to compare the teacher education system in countries that have reformed, or are in the process of reforming, their informatics education by reflecting ongoing social changes and developments in IT. The teacher education systems in Finland, Germany, Japan, the UK and US were compared. As a result of the study it was found that (1) the results did not differ according to the teacher education institution, (2) there was a focus on a minor subject, and (3) there were various routes for teacher training. The systems for special graduate schools were found to be developed, probation period after graduation was more than one year, and license renewal systems were being enforced. Based on these results, it was proposed that (1) more teachers be recruited to attend graduate schools and (2) that software training be given to all teachers as a minor. Finally, a license renewal system for revaluating teachers' qualifications was also proposed. This research is meaningful in that it compared the teacher training system in Korea with five major developed countries.

Computer education is gradually focusing on a wide variety of areas of expertise such as production of visual media and software development, instead of on the use of ICT like before. Particularly, computer courses related to production of image media require a complex practice procedure and repeated practice, making the future hands-on work difficult. Therefore, this study tried to verify the effect of the change in running methods of the "computer graphic" course from offline to blended learning. This analyzed the students' lecture satisfaction survey results of before and after the change. As a result, blended learning was well received and led to the small variations in the scores of the satisfaction surveys between the lecturers. Additionally, many students responded that the blended learning was more effective in their satisfaction surveys.

This study examined student- and school-level background and ICT factors that affected PISA 2015 Collaborative Problem Solving (CPS) for Korean students (4863 students from 142 high schools). A two-level hierarchical linear model (HLM) was analyzed from the basic model (model 1) with no predictors to the final model (model 5) with all predictors. Results showed that first, gender, socioeconomic/cultural backgrounds, cooperation level positively predicted CPS scores while perceived unfairness of teacher negatively predicted the outcome. Second, the more frequently ICT was used for out-of-school learning purposes, the less frequently ICT was used for entertainment purposes, and the less frequently ICT was used in schools, the higher CPS scores were. Considering ICT autonomy and social interaction variables measured for the first time in PISA 2015, students who were more interested in ICT and more autonomous in using ICT devices achieved higher CPS scores. On the other hand, the more students considered ICT important as social interaction, the less they gained CPS scores. Third, in terms of school-level characteristics, the smaller the students behavior detrimental to learning, the higher the teachers perceived positive working environment, and the fewer the number of computers available per student, the higher CPS scores were. To facilitate computer-based collaborative problem-solving competence, it is important for students to have interest and autonomy in using ICT. In addition, the guidelines of ICT use and SW curriculum need to be established in order to increase the effectiveness of using ICT device in school.
