WebRTC ile gerçek zamanlı sanal sınıf uygulaması

Öz

WebRTC (Web-based real time communication) web tabanlı gerçek zamanlı ses, video ve veri iletişimine olanak sağlayan açık kaynak iletişim projesidir. Bu çalışmada WebRTC teknolojisi kullanılarak geliştirilen Sanal Ders uygulaması ile sanal sınıf ortamlarının getirdiği etkileşim eksikliği, öğrencinin çevrimdışı takip ettiği derslerde sorularına karşılık bulmada yaşadığı zorluklar, uygulama için eklenti ve benzeri program kurulumu ihtiyaçları, platform ve sistem bağımlılığı gibi olumsuzlukların giderilmesi hedeflenmiştir. Bu uygulamada; tek bir HTML5 uygulaması ile belirlenen bir zamanda internet bağlantısının olduğu herhangi bir yer ve cihazda hiçbir ek yazılım veya eklentiye gerek duyulmadan kesintisiz anlık sesli ve görüntülü iletişim kurabilecek bir sanal sınıf ortamı sağlanabilmektedir. Ayrıca eğitmen ve katılımcılar arasındaki etkileşimin arttırılması amacıyla anlık mesajlaşma, doküman paylaşım ve sunumu ile beyaz tahta uygulaması da eklenmiştir. Sanal Ders ile eğitiminde mekâna ve cihaza bağlı kalmadan özgür bir ortam sağlanabilmektedir. Böylece hem eğitimde eşitlik hem de zaman ve maliyet tasarrufu sağlanabilmektedir.

A real time virtual classroom implementation with WebRTC

Öz

WebRTC is an open source communication project which provides the communication of web based real time sound, video, and data. In this study, some difficulties are analyzed and eliminated with the application of Sanal Ders developed by using WebRTC technology. These difficulties can be listed as follows: the lack of real communication in virtual classroom environments, the issues that the students studying offline face while they get no responses to their questions, the requirement for new plug-ins or the program installations, the dependency to the system and platform. This application provides the virtual classroom environment that has an instant and continuous voice and visual communication with only an HTML5 application during the specified time period and place. The device connected to the internet is sufficient and no additional software and plug-ins are required. Instant messaging, document sharing and presenting, and white board application are also added to increase the communication facilites between the instructor and participants. Use of Sanal Ders enables to create free environments from place and device in educational process. This framework improves the education by both creating equality and providing efficiency in time and cost.
