Finally, talking about all the technologies which are potential tools for language teaching, one thing stayed unanswered for me; which of the techs i will use for my teaching. The answer for me is obvious, Google products which are just created for education. At present i am trying at least to use one of theGoogle products for making my teaching or better say tutoring more effective, which is Google mail and Google Drive.
So, Reviewing all the very important technologies, gave me more understanding of choosing the right thing for my teaching.
This is not the End, everything is just began.
