This poster introduces a case study of redesigning an introductory CS course into fully online and its evaluation. The course redesigned is an introductory computer science course aiming to enhance non-CS major students' engagement. We applied flipped learning and active learning approach to the course design, utilizing interactive learning platforms. The proposed course offered a more immersive and satisfactory experience, even in a fully online course. The questionnaire results after the practice in the 2020 term showed that students rated significantly higher than that of 2019 in terms of difficulty level, amount of content, manner of delivery, course materials, consideration of course design, the structure according to the syllabus, learning outcomes, and satisfaction.

Large-scale online discussion platforms are receiving great attention as potential next-generation methods for smart democratic citizen platforms. One of the studies clarified the critical problem faced by human facilitators caused by the difficulty of facilitating large-scale online discussions. In this demonstration, we present our current implementation of D-agree, a crowd-scale discussion support system based on an automated facilitation agent. We conducted a large-scale social experiment with Nagoya local government. The results demonstrate that the agent worked well compared with human facilitators.

"Computer Science (CS) Unplugged" is an educational method for introducing non-specialists to concepts of CS through hands-on activities that don't require the use of a computer. Often the deeper concepts of CS have been considered as being too difficult for elementary and middle school students, and many educators teaching "IT" are not even aware of the richness of the topic. CS Unplugged methods have been used successfully with students of a wide range of ages. In this paper, we analyze the structure of CS Unplugged activities to identify the elements that make them work well. Based on the analysis, we propose a design pattern which will be useful as a guideline for developing new activities, and to revise existing ones. We also describe our experience developing original teaching material, using the pattern as a benchmark for evaluation.

It is expected that vehicles have on-board terminals to communicate with the fixed network and also with surrounding vehicles in the near future. This paper explains our developed inter-vehicle P2P (peer-to-peer) communication experimental on-board terminal, we nicknamed it "V-ant", which has the feature of adopting AODV (ad-hoc on-demand distance vector) protocol, control of AODV packets transmission direction using GPS data, and adaptive media switching between vehicle-to-vehicle ad-hoc communication, communication through access points, and PHS (personal handy-phone system in Japan).

Vehicle-to-vehicle (peer-to-peer) communication is expected to play an important role in ITS (intelligent transport systems). This paper proposes an adaptive media switching method for future vehicle-to-vehicle communication. Our method adopts an approach to select the most suitable radio communication media from several possible types based on the vehicle locations, available media and communication quality. Before the network configuration of inter-vehicle and roadside-vehicle communication changes, the vehicle detects it and then initiates the media reselection. During such media switching, our proposed HTTP-based session layer mobility avoids any interruption of communication. We conducted field tests using several experimental vehicles. The results verify that our proposed method is effective in selecting the most suitable media, and disconnection of communication during the media switching is also avoided

This paper presents novel broadcast methods for an inter-vehicle communications system for ITS. During inter-vehicle communications, it is essential that emergency information be broadcast to surrounding vehicles. Emergency information such as emergency-vehicle-approach information and traffic accident information are needed by vehicles in a particular area. By limiting the broadcast direction, the proposed methods can provide broadcasts to a particular area and avoid mistakenly notifying other areas where the information is not needed. We developed a simulation and experimental system for the proposed method and confirmed that the information is broadcast to the desired area.

we have developed a system to support communication between students and teachers on the computer network.By using e-mail, they can exchange information, e.g., questions and reports whenever and wherever they can access the Internet.And by using W'orld lk7ide Web, the teacher can provide impressive teaching material for the student.Moreover the system provides "easy maintenance" facilities.So the teachers who use it don't have to master the details of the system.They can use it easily by following various navigational information instructions.And to use the system for many years, it can reuse information and setups which were made previously.1
