We could be in a different world when we play games, or when we are in social networking. But, how about virtual classroom? Is it useful and powerful enough to change the physical interaction between students and their teachers? What is the advantages?

A teacher’s avatar has another power that could not be found in physical space. This technology enable teachers to make face-to-face contact with their students, which is the main rule to conduct a good interaction. In a video game, everything we do must have intention to produce such a behavior, but here they don’t have to. In virtual reality, magnetic sensors and video camera are able to detect what a student do and instruct the computer to redraw avatar performing the same action. So, it feels as if they are still in the same classroom.

Another advatages that we could find is that digital learning helps to increase motivation of the class to be more active in learning. However, there could be a wide range of personality type among students, especially in a large groups of students, for example, introverts and extroverts. Some students might prefer communication accompanied by nonverbal cues, like gestures and smiles, others may prefer a less‐expressive speaker. On some psychological studies, there is this term called chameleon effect, which is defined as when one person nonverbally mimics another, displaying similar posture and gestures, he maximizes his social influence. Some studies result that students more direct their gaze at mimicking teachers than at teachers who are behaving normally. This make class look alive.

In the physical world, every room has a sweet spot. It varies from one room to another, but it is often center or front area. And only some student can sit in the sweet spot. But because virtual rooms are drawn separately for each user, every single student’s avatar can be sitting in the sweet spot . It can increase the level of learning of the students. Moreover, they can be participative verbally and create an active learning atmosphere in the class. And some students are more active in virtual class, they are more confident in giving opinion and arguments.
