The development of IT technology emphasizes the importance of training IT professionals, and the need for education for elementary and secondary education as well as adult education for training technical talent is expanding. In particular, information curriculum will be added as an essential course from the 2015 revised curriculum, and IT technology will be understood in the curriculum for elementary and secondary schools and will be required to develop applicability to solve problems based on understanding. Currently, research is under way to integrate IT technologies to provide new services, and if the use of personal information is required in the process, thorough security for the leakage of personal information is pre-empted. It also prevents the identification of personal information in the process of transmitting data to the outside world. In this paper, we propose a training method for elementary school subjects to understand the non-identification process that occurs in the process of transferring data using pipe games so that they can understand the principles of non-identification and develop applications to solve real-life problems.

In this paper, we propseded the Youngwoo keyboard to help the communication disorders experienced by patients with dysarthria. Existing methods for communication by patients with dysarthria include a letter board with consonants and vowels, a mouse using eye tracking, and communication assistance applications. However, there was a delay of more than 5 minutes per sentence, so there were many difficulties in communication. However, unlike the existing method, the proposed method has been improved so that the patient with dysarthria can communicate by completing the sentences with eye movements. In the conclusion and future work of this paper, the educational use value for Yeongwoo keyboard was analyzed, and it was shown that this training can be of great help to families with ALS patients. The proposed keyboard will be able to improve the difficulties of families by facilitating communication of patients with dysarthria.

This study was to examine the needs among elementary school dietitians (n = 115) for developing a nutrition information internet site for children. A survey questionnaire included general characteristics, internet use regarding health and nutrition information, and needs for developing a nutrition information site. The mean age of the subjects was 36.2 years. The higher working experience group (> 10 years of working as dieticians) had higher mean age (p < 0.001), had a larger number of enrolled students at school (p < 0.01) and the number of those receiving school lunch (p < 0.01) than the counterparts (${\le}10$ years group). Sources of health and nutrition information were mainly PC/internet (60.4%) and seminar (14.4%). About 95% used health or nutrition information using the internet, however, the majority of users (71.6%) used internet information only when they needed it. Major reasons for using internet information was 'to get nutrition education materials' (63.8%) and 'to obtain general nutrition information' (21%). One third of the subjects were satisfied with nutrition information internet sites; major problems with internet sites were 'lack of content' (38.9%) and 'lack of practical information' (33%). These characteristics regarding internet use were not different between work experience groups. Major problems with nutrition education were 'lack of nutrition educational materials' (41.1 %) and 'lack of nutrition education skills' (32.1%). These were significantly different between the work experience groups (p < 0.01). Subjects preferred CD/internet to leaflet/booklet as nutrition educational materials. In developing nutrition sites for children, subjects wanted topics such as obesity assessment, dietary assessment, and obesity. Subjects responded that contents of nutrition information should be 'suitable to the children's knowledge levels' (31.1%), 'interesting enough by including quizzes, games and songs' (27.8%), 'inserting many illustrations/icons' (16.3%). In terms of designing internet sites for children, they wanted that internet sites should 'be easy enough to find the sites' (29.2%), 'use illustrations and characters' (24.8%), 'use communication channels such as Q&A' (18.7%). Needs for developing internet sites for children were not different by the work experience group. This study suggests that web sites for children should be carefully developed considering the contents and design, have less information with more illustrations, designed to induce the interest of children, as well as including sections such as eating habit assessment and games.

The purpose of this study is to analyze cases on teaching solutions exploration of Wythoff's game through using the analogy for the gifted elementary students, to suggest useful teaching methods. Students recognized structural similarity among problems on the basis of relevance of conditions of problems. The discovery of structural similarity improves the ability to solve problems. Although 2 groups-NIM game with surface similarity is not helpful in solving Wythoff's game, Queen's move game with structural similarity makes it easier for students to solve Wythoff's game. Useful teaching methods to find solutions of Wythoff's game through using the analogy are as follow. Encoding process helps students make sense of the game. It is significant to help students realize how many stones are remained and how the location of Queen can be expressed by the ordered pair. Inferring process helps students find a solution of 2 groups-NIM game and Queen's move game. It is necessary to find a winning strategy through reversely solving method. Mapping process helps students discover surface similarity and structural similarity through identifying commonalities between the two games. It is crucial to recognize the relationship among the two games based on the teaching in the Encoding process. Application process encourages students to find a solution of Wythoff's game. It is more important to find a solution by using the structural similarity of the Queen's move game rather than reversely solving method.

As software transforms the structure of industry, it becomes a key measure in determining market competitiveness. Therefore, various educational efforts have been attempted in Korea to cultivate software professionals to secure software competitiveness. While previous studies had focused mainly on the cognitive effectiveness of software education, the authors tried to focus on affective perspectives. The authors, therefore, aimed to analyze the predictive power of the recognition of software importance and learning flow on affective outcomes, such as efficacy of computational thinking skills, and attitude toward, and satisfaction with, software education. The data were collected from 103 sixth grade students who participated in a software education. Results show that software importance and learning flow had significant predictive power on affective outcomes; Learning flow mediated the relationship between software importance and affective outcomes. This study provides practical implications for improving affective outcomes in the design and implementation of software education.

In 2021, AI basics were introduced in the high school curriculum. There are many worries that the problem of utilization-oriented education will be repeated with the introduction of artificial intelligence education rather than the principles that occurred when ICT was applied to education in the past. Most of the existing AI education platforms focus only on the use of AI. For artificial intelligence education of middle school students, there are difficulties in learning about the process by which artificial intelligence derives results and learning the principles of artificial intelligence algorithms. Recently, as the educational application of metaverse has become a hot topic, research has been started to improve learning achievement by arousing students' immersion and interest. This research developed educational game contents about decision tree algorithm using metaverse as educational contents that can be used in middle school AI education. By applying games to education, it was intended to increase students' interest and immersion in artificial intelligence, and to increase educational effectiveness. In this paper, the educational effectiveness, difficulty, and level of interest were analyzed for pre-service teachers regarding the developed game content. Based on this, a future principle-oriented artificial intelligence education method was suggested.

This study aimed to evaluate the effects of utilizing educational game content for science learning on science-related attitudes. The content was applied to 24 students in an after-school science club at an elementary school in Gyeongsangbuk-do Province followed by a pre and posttest analysis using the Attitude About the Relevance of Science Test and the Creative Personality Test. This study used Tino's Journey, which was developed by the Korea Creative Content Agency and is currently distributed for free through the Ministry of Education to develop nine lessons that include scientific scenarios and concepts presented in the game. The results demonstrated that science lessons utilizing educational game content significantly influenced the science-related attitudes of the students. Among the subdomains, enjoyment of science lessons increased the most followed by the attitude toward scientific inquiry, social meaning of science, and hobby of science. However, the commonness of scientists, acceptance of scientific attitudes, and career in science did not reveal significant differences. This study classified the students into two groups (i.e., high and low, n=12 each) using the Creative Personality Test in advance. This study performed covariate analysis with the score for pre-science-related attitude as the covariate. Result revealed that the scores for science-related attitude significantly differed between the high and low groups. Specifically, the increase in the scores of the low group was larger than that of the high group. Lastly, the study presented implications for the utilization of educational game content in science learning.

The domestic game industry has constantly developed in a short time by concentrating on online games, and keeps growing as a highly added value industry. Also, in the social aspect, it has been seeking various alternatives to place online games as positive and new play culture in the digital era by avoiding negative criticism on game addictiveness. One of important factors in expanding the infrastructure of the game industry and developing it as a type of culture is not simply to develop the existing core genres (on the basis of profits), but to promote the approach of mixture with various contents and of positive functions and thereby enlarge users through various game genres. That is, it is to design games with positive themes and easy immersion by targeting a variety of game users. Such expansion of game design approach is a starting point to develop the infrastructure of the game industry. In the aspect, training professional human resources on the basis of academic and educational process is of significance. Therefore, this work was intended to suggest examples of design approach education based on creativity subject among various subjects with positive functions, and then propose an education process to which Capstone design education contents were applied.

The purpose of this paper is to develop RPG based learning content for English low-achievers at elementary school and to verify the educational effectiveness of this content. Design strategies were elicited by reviewing curriculum and literature. Educational RPG was developed based on ADDIE model. The researchers implemented them in four 5th-grade English low-achievers for two months. Free writing, interviews and observations of the homeroom teacher were conducted to verify the effectiveness of the content. As a result, English low-achieving students became interested in RPG itself, raised their expectations and became more satisfied in learning. When students completed missions while playing games, they gained satisfaction and were challenged by the new missions. This had a positive effect on learning motivation, or "continuing motivation" as mentioned by Keller.

Since the entering SW-centered society in which people make the best use of SW in order to express their own personal ideas or to solve problems, the significance of SW education has been emphasized. It is generally known that storytelling provides motivational and contextual environments. This study conducted an experimental research to find out how Aesop's fables-applied SW educational program would influence computational thinking. Of these students who had participated in an SW educational camp on every Saturday for a total of 6 weeks, the experimental group learned on basic concepts of Scratch programming as working on Aesop's fables and they were led to diverse SW activities such as stories, games, simulations arts, and others. After that, the study carried out a comparison research in relation to the groups' SW concepts, SW implementation and attitudes toward SW education. The result shows that the experimental group came up with higher levels of SW concepts, implementation and positive attitude toward SW education.
