Recently, artificial intelligence(AI) has been used throughout society, and social interest in it is increasing. Accordingly, the necessity of AI education is becoming a big topic in the education field. As a response to this trend, the Korean education authorities have also announced plans for AI education, and various studies have been performed in academic field to revitalize AI education in the future. However, the curriculum research on what differentiates AI education from existing SW education and what and how to train AI is still in its infancy. In this paper, Therefore, we focused on the experiences of elementary school students in solving problems in their own lives, and developed a teaching-learning model based on design-based research so that students can design a problem-solving process and experience the process of feedback. We applied the developed teaching-learning model to the problem-solving process and confirmed that it increased students' understanding and satisfaction with AI education.

The present study is devoted to the development of a simplified teaching method whereby the control data of the 3-dimensional operations of a playback-type trial robot can be stored in a personal computer. The control data of the 3-dimensional operations are given using an instruction wand handled by an operator. The operator's task is only to track a desired robot path with the wand. The 3-dimensional position of the wand are measured by ultrasonic devices, the principle of which was developed for this study and is introduced in detail. In order to clarify the applicability of this method, experts were performed with respect to a continuous-path teaching and a pick-and-place task teaching which are typical jobs of robot operators.

In this paper, we analyze the course 'computer' on middle and high schools. and propose new organization of the course to enhance the ability of self-directed learning. We also develop a learning system for new organization, based on self-directed teaching and learning principles. The developed learning system makes students choose the topics according to their interest and advance learning by the schedule they set by themselves. To promote students' participation, the teacher also gives students various learning tasks. Through e-board and Q&A, we also accelerate mutual communication among teachers and students, to do teaching-learning activities vigorously.

In the existing curriculum of the Elementary computer Education emphasizes students' problem-solving ability and knowledge of informatics. However, current computer education focus on using application program. In order to raise students' problem-solving ability and logical thinking ability, it is necessary to learning about computer science education. Thereupon, this study applied unplugged learning method to the elementary student. To apply the play-based unplugged learning method to the area of information representation. As a result, unplugged learning method produced higher academic achievement than the lecture model. Also it was more positive in the affective area than the lecture model.

In this study, we proposed a pre-service teacher training program that assists efficiently the conceptual comprehension and teaching skill development of computer science education. The program is integrated with Protype Theory and Example Theory based on cognitive psychology. And also the real teaching activities based on Unplugged Learning are provided for conceptual comprehension of computer science education as well as for learning computer science. This program was applied to 31 pre-service teachers for one semester. The results show that this program is very effective for pre-service teacher training of computer science education.

사회 패러다임의 변화는 교육 패러다임의 변화를 요구하며, 교육 패러다임의 변화는 교사의 역할도 함께 변화할 것을 요구한다. 현대 사회는 많은 지식을 습득한 인재를 양성하는 것보다, 지식을 습득하는 방법과 습득한 지식을 활용하여 문제를 효과적으로 해결하는 인재를 양성할 것을 요구하고 있다. 따라서 교사는 현대 사회가 요구하는 학습자를 양성하기 위하여 지식 전달자의 역할에서 문제 해결자를 양성하는 역할로 탈바꿈해야 한다. 이를 위해서는 교사는 학습자가 교과에서 반드시 학습해야 하는 개념과 원리를 깊이 있게 이해하고 이를 활용하여 문제를 해결할 수 있도록 안내하는 역할을 해야 한다. 이러한 점에서 볼 때 프로그래밍은 교사의 수업 전문성 향상을 위한 훌륭한 도구이다. 프로그래밍은 교사가 원하는 교수 학습 자료나 추상적인 내용을 시각적으로 확인하는 자료, 혹은 사람의 사고 능력으로 해결하기 어렵거나 시간이 오래 걸리는 문제들을 해결하는 자료 제작을 지원함으로써 학습자의 깊은 이해를 유도할 수 있다. 따라서 수업 전문성 향상을 위한 프로그래밍 교육 실천함으로써 교사가 사회에서 요구하는 인재를 양성하는 임무를 충실히 수행할 수 있도록 해야 할 필요가 있다.

Images in the textbooks influence the learning process. Students often see pictures before reading the text and these pictures can enhance the power of imagination of the students. The findings of some researches show that the images in textbooks can increase students' creativity. However, when learning major subjects, reading a textbook or looking at a picture alone may not be enough to understand the topics and completely realize the concepts. Studies show that viewers remember 95% of a message when watching a video than reading a text. If we can combine textbooks and videos, this teaching method is fantastic. The "TEXT + IMAGE + VIDEO (Animation)" concept could be more beneficial than ordinary ones. We tried to give our solution by using machine learning Image Classification. This paper covers the features, approaches and detailed objectives of our project. For now, we have developed the prototype of this project as a web app and it only works when accessed via smartphone. Once you have accessed the web app through your smartphone, the web app asks for access to use the camera. Suppose you bring your smartphone's camera closer to the picture in the textbook. It will then display the video related to the photo below.

There are making epoch changes of a teaching method and educational contents as information communication technology (ICT) introduced to school education. The 7th curriculum induces that teaching hours should be assigned to education using ICT more than 10% of all classroom work hours. In this study, we established basic course of courseware design for applying ICT to physical education effectively in the 7th curriculum. We developed distance-learning program for motion of short-distance race and the entire his power race in middle school using Web. Flash and Database. And we evaluated efficiency by students that are 4 classrooms (140 persons) after teaching using the WBI. According to results of questions and a test, the students expressed that education using ICT make understanding of instruction substance effectively. concentrating their attention on teaching and concerning in teaching actively.

The purpose of this study is to develop and apply the algorithm teaching materials centered on plays(ATMCP) to improve problem-solving abilities of elementary students. For this goal, the ATMCP were reviewed by the expert group and tested them out on 71 fifth-grade elementary students in Daegu, Korea during the 6 weeks. We divided students into two groups: one is the group of the ATMCP and the other is the group of conventional algorithm teaching materials(ATM). And we analyzed the change of the problem-solving ability of each group between before and after using two types of teaching materials with the Mixed ANOVA. The result showed that there was a significant difference in students' problem-solving abilities between before and after using them and the group of the ATMCP was greater improvement than the group of the conventional ATM in a problem-solving ability.

The purpose of this study was to develop and apply the elementary teacher training course for educational programming language based on TPACK in order to make elementary school teachers fully equipped with teaching efficacy for SW education. As a result, the informatics teaching efficacy of the teachers in the experimental group who participated in EPL training course developed based on TPACK was statistically more significant than the teachers in the control group(t=4.13, p<.001). The dependent sample t-test of the experimental group showed a statistically significant increase with t=4.57 (p< .001). It proved that TPACK-based teachers' training course is effective to improve teachers' informatics teaching efficacy. It is suggested that the development of SW education teacher training course should be systematically structured considering TPACK framework.
