Language power is about really communicating. It is not about getting a high grade in a language course. Millions of people around the world have experienced formal language training and received high marks in schools and universities. However, far too many of these people with formal language and high marks to show for it, are unable to really communicate in the language. This disappointment is often first experienced when the language learner is able to turn on a television program in the language. The depression sets in when the learner realizes that after so many years of study he/she is not able to understand what is happening on the television.  In this scenario we see that judging by the high marks at school, the speaker has high academic knowledge. However, because of their inability to understand what they see and hear on the television, they have low language power.
