A English learner need not only to learn new words, but to remember them.  As a matter of fact, learning is remembering.  However, simply repeating newly learned words is not a good way to move thoese new words to the permanent memory.  A good method to remember words is to integrate new knowledge into old–”practice makes perfect.”  A good method I want to share is “mnemonics.”  The best-know mnemonics is that we can associate an image that connects the pronunciation of the second language word with the meaning of a first language word.  For example the word “pencil” sounds like the Chinese word “拍手,” so we can draw a picture of a pencil clapping his hand.  I think mnemonics is fun for learning words and it may be a good idea to allow students a few minutes to try to find those keywords for mnemonics.
