영화 <코러스>에서 아이들이 학교에서 쫓겨나는 선생님을 위해 종이비행기에 편지를 써서 창밖으로 날리는 장면은 관객들에게 많은 감동을 주었다. 언제부터인지 알 수는 없지만 종이비행기는 사람들의 희망을 담아 하늘로 전달하는 메신저의 역할을 하고 있다. 그래서 종종 꿈이 실현되기를 바라는 마음에서 종이비행기를 날리는 행사가 진행되기도 한다. 하지만 종이접기가 종이비행기처럼 상징적 의미가 아니라 실제로 세상의 많은 것을 바꿔놓고 있다. 그렇다면 종이접기가 어떻게 세상을 바꿔 놓고 있을까?

전통적인 자동차는 운전자의 판단과 조작에 의해서만 움직여야 하나 최근 자율주행자동차가 선을 보이고 있으며, 미래에는 운전자의 조작 없이 자동차가 스스로 목적지를 찾아가는 완전자율주행자동차 시대가 올 것으로 예견된다. 본 고에서는 자율주행자동차의 출현에 따른 지상파 방송의 역할을 제시한다.

With wide spread of smart devices, the use of children's smart devices were increased. We have performed an exploratory study about children's use of smart devices in the viewpoint of lives of children. The children was encouraged on the school centered learning by their parents. In this study, we wanted to explore the state of life of children's using of smart devices in the view of the children's life at the age of information society. The results show that there was a difference in children's using of smart devices between big and small city. This research shows that the students have the lack of the experiences of learning of desired usages and learning with devices. In the play with the non-electronic media, outside play was more than indoor play. Half of the answers at the amount of time to play the game and to watch the TV were "within an 1 hour". We know that the proportion of children's indoor play portion is more than outdoor play of it.

With the society rapidly changing, children are being asked respond quickly to these changes. Therefore, how children learn and think comes before what to teach, and we need to come up with ways to nurture their ability to proactively control their lives and studies. We attempt to use the technique of Accelerated learning, which focuses on the student's own ability toacquire and use information, to enhance the efficiency of information technology education. We designed the PLAY model based on accelerated learning and Multiple Intelligence Theory, and conducted ten experimental sessions on two groups of 70 second grade elementary school students.

In this paper, we design and implement an educational robot system that can use scratch education with the function of user demanding to perform robot education in actual school site in an embedded environment. It is developed to enable physical education for sensing information processing, software design and programming practice training that is the basis of robotic system. The development environment of the system is Arduino Uno based product using Atmega 328 core, debugging environment based on Arduino Sketch, firmware development language using C language, OS using Windows, Linux, Mac OS X. The system operation process receives the control command of the server using the Bluetooth communication, and drives various sensors of the educational robot. The curriculum includes Scratch program and Bluetooth communication, which enables real-time scratch training. It also provides smartphone apps and is designed to enable education like C and Python through expansion. Teachers at the school site used the developed products and presented performance processing results satisfying the missionary needs of the missionaries.

The need for an environmental monitoring system that obtains and provides environmental information in real time is increasing. In particular, in the case of water quality management in public waters, regular management must be conducted through manual and automatic measurement by law, and air pollution also requires regular measurement and management to reduce fine dust and exhaust gas in connection with the realization of carbon neutrality. In this study, we implemented a system that can measure and monitor water pollution and air pollution information in real time. A hovercraft capable of moving on land and water simultaneously was used as a measurement tool. Water quality measurement and air pollution measurement sensors were installed on the hovercraft body, and a communication module was installed to transmit the information to the monitoring system in real time. The structure of a hovercraft for environmental measurement was designed, and a LoRa module capable of low-power, long-distance communication was applied as a real-time information transmission communication module. The operational performance of the proposed system was confirmed through actual hardware implementation.

Recently, with the introduction of drones, a core technology of the 4th industrial revolution, various convergence education using drones is being conducted in school education sites. In particular, drone theory and practice education is being conducted in connection with free semester classes and career exploration. The drone convergence education program has higher learner satisfaction than simple demonstration and practice education, and the learning effect is high due to direct practical experience. However, since practical education is being conducted for a large number of learners, it is impossible to restrict and control the flight of a large number of drones in a limited place. In this paper, we propose a monitoring system that allows the instructor to monitor multiple drones in real time and learners to recognize collisions between drones in advance when multiple drones are operated, focusing on education operated in schools. The communication module used in the experiment was equipped with GPS in Murata LoRa, and the server and client were configured to enable monitoring based on the location data received in real time. The performance of the proposed system was evaluated in an open space, and it was confirmed that the communication signal was good up to a distance of about 120m. In other words, it was confirmed that 25 educational drones can be controlled within a range of 240m and the instructor can monitor them.

In this study, a plastic bottle recycling bin system that utilizes an infrared sensor was implemented. The proposed system consists of a recognition unit, a control unit, an alarm unit, and a driving unit. The recognition unit detects the plastic bottle, measures the distance between the plastic bottle and the infrared sensor, extracts the value of the bottle, compares the extracted value with a standard range, and then transmits the control value to the control unit if the extracted value of the bottle is outside the standard range. In this case, the result of the presence or absence of a brand label or bottle cap is transmitted to the controller. The control unit opens the entrance of the recycling bin or alerts the alarm unit according to the result value transmitted from the sensor unit. In order to implement the proposed system, the recognition unit was implemented with an infrared sensor, and the control unit was made with an Arduino IDE controller, based on the C programming language. Additionally, the recognition unit and the control unit are able to communicate using analog signals. The proposed system accurately judges the presence or absence of a brand label and bottle cap of plastic bottles according to a predetermined algorithm. It then blocks the entrance of the recycling bin when a brand label or bottle cap is still attached. As the amount of waste discharged per person is relatively high and the majority of such waste is incinerated rather than recycled, the system proposed in this study is expected to increase the recycling rate of plastic bottles.

초등학교 정보통신기술교육은 정보 사회를 살아가는 학생들에게 학습과 일상 생활에서 필요한 최소한의 컴퓨터 활용 능력을 길러 중학교에서 보다 깊이 있게 다루어질 학습과제를 해결하기 위한 기초 기능을 다지는데 목표가 있다. 그런데 정보통신기술교육을 할 때, 여러 가지 요인으로 인하여 학생들의 개인별 ICT 활용능력 차이가 매우 크게 나타나 있는 실정이다. 따라서 기존의 전통적인 일제식 수업으로는 교수-학습을 하는데 많은 어려움이 있으므로 초등학생의 ICT 활용 능력과 개인차를 고려한 정보통신기술교육의 수준별 교육과정 모델을 개발하고, 개발된 교육과정을 수준별 수업모형에 적용하는 방안을 연구하였다.

제7차 교육과정에서는 세계화 정보화, 다양화를 지향하는 교육체제의 변화이다. 이와 같은 변화에 맞추어 2001학년도부터 재량활동을 통해 ICT 교육을 1,2학년에 한하여 실시하고 2002학년도에는 3,4학년으로 2003년에는 5,6학년까지 그 범위를 확대하여 실시되고 있다. 정보통신기술교육은 지식평가나 능력위주의 평가대신에 실습위주로 이루어지며 컴퓨터를 바르게 이해하고 활용하도록 도와준다. 타 교과에서는 수행평가를 영역별로 실시하지만 정보통신기술교육에서는 영역별 수행평가를 실시하지 않고 전반적인 평가를 하고 있다. 컴퓨터교과도 수행평가를 실시하여야 바람직한 평가가 될 것으로 생각되어 현재 일선학교에서의 컴퓨터 평가실태를 분석하고 그 문제점을 제시해 본다. 정규교과로 되기 위해서는 컴퓨터영역별로 세분화 된 평가준거 및 문항 등이 평가의 밑바탕이 되어야 한다. 따라서 본 연구자는 교육현장에서의 초등 정보통신기술교육에 대한 효율적인 수행평가방안에 대하여 연구하고자 한다.
