Future of Virtual classrooms
Ever since virtual reality (VR) has entered the classrooms, it has transformed the way students used to learn. A few years ago, who would have imagined that sitting in a class, virtual field trips will be possible? Companies like Google have made this possible through their virtual field trip systems that give an immersive experience to the students by making far-flung places more discoverable.
VR has the ability to grab the attention of students and because of the 3D interacting environment, it encourages students to develop their own objects. And this in turn makes them creative.
3D hologram: The future
3D hologram is an innovation that will transform electronic modes of teaching. With this technology it is possible to create a classroom environment even when the teachers and students are at home or anywhere else. The 3D technology operates by creating the illusion of three-dimensional imagery. A light source is projected onto the surface of an object and scattered. A second light illuminates the object to create interference between both sources. Essentially, the two light sources interact with each other and cause diffraction, which appears as a 3D image.
It’s one of the most promising form of mobile learning which is believed to take over the classrooms in the future. It allows teachers to provide instruction from home with holographic images of students via an electronic multimedia device. The experience created by 3D hologram is as close as it gets to being real. The students are able to see the teacher and fellow learners using mobile devices. This also gives teachers and students the impression that they are in the same physical space. However, as compared to other mobile learning technologies, this one comes at a high cost. Another concern which can hamper its smooth execution is slow internet speed.
Various advancements in technology have replaced traditional chalkboard teaching to a digitally-enabled one which is more interactive. The network–based methods are used to complement classroom education to reduce the effects of distance, making it independent of time and physical location.
The 3D hologram technology is a step ahead of these because of the near real experience it gives. And that’s the future. It will help in creating a physical classroom scenario in an e-learning framework with so much accuracy that the students will forget about the distance between them and the teacher. So far we have seen e-learning being practiced mainly through interactive forums, messaging, chat, wiki. However, smartphones and tablets are slowly taking over the e-learning market, boosting audio-visual communication.
All these technological developments are paving the way for a future where learners can pursue education and work simultaneously. Also, studies have indicated that virtual learning results in better retention and understanding of a given topic.
