It is still a mystery why, as Robert C. Gardner puts it “that some people can learn a second or foreign language so easily and so well and while others, given what seem to be the same opportunities to learn find it almost impossible?” [1] No audio-visual suite, no matter how high tech and expensive, will be able to raise the grades of students who find it impossible to hold the complexity of grammar rules in their heads.
