ICT education guidelines revised in 2005 reinforce computer science elements such as algorithm, data structure, and programming covering all schools. And Ministry of Education emphasizes STEAM education. Most important is that "How instruct them". This means necessity of contents. So this paper suggests learning method of Stack and Queue using LEGO MINDSTORMS NXT. The main purpose is that how stack and queue are used, when robot explore realistic maze. Teaching and learning strategies are algorithm, flowchart, and NXT-G programming. Simple maze has path in left or right, but complex maze has three-way intersection. These are developed by authors. Master robot explores maze and push stack, and then return to entrance using stack. Master robot explores maze and transmits path to slave's queue. And then slave robot drives without exploration. Students can naturally learn principles and applications of them. Through these studies, it can improves ability of logical and creative thinking. Furthermore it can apply to ICT and STEAM education.

Much research has been conducted in educational robot, a new instructional technology, for K- 12 education. Several studies have shown that educational robot provides effective learning opportunities for students in both content areas of STEM(science, technology, engineering, and mathematics) and critical academic skills, such as collaboration, problem solving and communication skills. However, most studies to date on applications of educational robots have been conducted outside the formal education setting. This study analyzed the influence of using robots in an elementary school science class in Korea with regard to science learning motivation. A total of 121 students in fourth and fifth grades participated in the study. The experimental group was taught using robots in the science class, while the control group was taught using traditional methods. Analysis of covariance (ANCOVA) was conducted to compare the between-group differences in learning motivation before and after the experiment; an interview was also conducted for the experimental group. The study results showed a significant improvement (p<.05) in both learning motivation in the experimental compared with the control group. There was also positive response to learning with a robot. This study will play an important role in research on the use of educational robot in formal education in the future.

Radial distance sensors are widely used for surveying and autonomous navigation. It is necessary to train the operation principle of these sensors and how to apply them. Although commercialization of radial distance sensor continues to be cost-effective through lower performance, but it is still expensive for educational purposes. In this paper, we propose a distance sensor module with object tracking using radial array of low cost phototransistor which can be used for educational robot. The proposed method is able to detect the position of a fast moving object immediately by arranging the phototransistor in the range of 180 degrees and improve the sensing angle range and track the object by the sensor rotation using the servo motor. The scan speed of the proposed sensor is 50~200 times faster than the commercial distance sensor, thus it can be applied to a high performance educational mobile robot with 1ms control loop.

This study uses the identification which is one of the critical components of psychological mechanism and enables replacing one's own self because of the needs of self-expression(disclosure) and creation. The study aims to improve educational effects using the realistic by increasing sense of the virtual reality and the attention. After the computer-based contents were developed and converted to be applied into robot, and then the contents were combined the student's photo and the avatar using automatic loading. Finally each one of the contents was applied to the students. The results of the investigation indicated that there were significant effects of the contents based on identification. In other words, the contents effect on student's attention, but not their academic achievement. The study could find the effect of the identification's application using the educational robot. We suggested that improving technical ability of the augmented virtuality as a face-detection and sensitive interaction may lead to the specific suggestions for educational effects for further research.

In the recently our 21C, it is a necessary to provide the VLSI design education methods based on the electronic information systems. In this paper, we will show a education model of the venture study programs concern with Micro-Robot making. The development education systems apply into the industrial fields from the specification major module instruction including improve the VLSI design capability using the Micro-Robot making for information communication techniques. Also, the development instruction model provides one in the field system to the industrial applications specification technical staffs and VLSI design for the venture education programs. We expect the proposed education systems extended into a new venture instruction program sets for technical major members.

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.

The revised 7th education course of information implies that students use variety of information devices to solve the common problems and it also includes the programming education for improving problem-solving abilities. Not only improving problem-solving abilities but also developing thinking skill is expected in programming education. However, traditional programming education is teacher-oriented and focused on language syntax. Accordingly, students have heavy cognitive load and it decrease students' interest of programming. Therefore, in this paper, a instructional method of programming using educational robot is proposed to improve interest of elementary students in concretive operation stage for effectiveness of programming education. Additionally, results of experiments show that proposed robot programming instructional method can be applied in elementary education.

본 연구는 인간의 자아표현 욕구와 창조적 욕구로 인해 자신을 대체할 산물들을 끊임없이 만들어 내는 과정에서 중요하게 작용되는 자기노출라는 심리를 이용하여 아바타와 학습자의 얼굴을 합성하는 증강가상을 통하여 가상세계에서의 현실감을 부여함으로써 학습자의 몰입을 유도하여 그 교육적 효과를 증대하고자 하였다. 이를 실증하기 위하여 컴퓨터기반으로 컨텐츠를 개발한 후, 로봇 컨텐츠로써의 활용을 위해 컨버팅하고 자동 로딩을 통한 학습자의 사진을 아바타와 합성시켰다. 실험 결과 자기노출기반 컨텐츠의 효과는 모든 집단의 경우에서 학습에 대한 집중도에는 긍정적인 영향을 주었으며, 학업성취도에는 유의미하지는 않지만 긍정적 효과를 가지는 것으로 나타났다. 이는 교육용 로봇을 활용한 자기노출 개념 적용에 대하여 긍정적인 결과라고 보여지는데, 보다 유의미한 결과를 얻기 위해서는 단순히 사진을 찍어 로딩시키는 증강가상보다는 얼굴검출을 통한 실시간 증강가상과 같이 증강가상 효과의 증대가 필요하다고 하겠다.
