Effectiveness or ineffectiveness of learning technology

I defineltly agree with the above statement. the reason being that in order for us as techers to teach a certain topic or lesson, in this case we are dealing with technology so it is very much important that we know all the necessary information about what will be though. because if we do not know and are just teaching from the top of our minds then the end result will be inffectiveness. Because at the end of the day the day the children will be taught the wrong information. But if we are equipted the the necessary information the learing technology will be effective.
