Gamig in Language Learning

Attention parents! This entry is especially for you.
Most of the time I hear parents complaining about the amount of time their children spend on the computer, just playing video games, and not studying. Today, I am here to advise you not to do that. Of course it is not healthy for children to spend hours by looking to computer screen but saying it is waste of time is also inaccurate.
Video games are actually quite useful for language learning. First of all, since the children do not see them as lessons, they are motivated to play and learn from them. Those games provide a huge source of vocabulary and besides do that in a context. For instance, in Minecraft they are supposed to build their own land and while doing that they unconsciously  acquire vocabularies like ''build, plant, improve'' and so on. Moreover, most of the online video games have chat rooms. And this gives them an opportunity to interact and communicate with others and thus using the language. To sum up, of course it is not logical that allowing your children to spend 5 or 6 hours on the computer. Yet, it might be better for them to be flexible (1 to 3 hours perhaps) instead of banning to play those games.
