As we have told you in other threads, we do not help with assignments. If you google 'Principles of Foreign Language Teaching', you will find a number of sites that may help you.
The grammar-translation method, the Silent Way, etc, are usually known as 'methods and approaches'.
Context is important. Please provide enough for us to be able to deal effectively with your question.
Your thread title should include all or part of the word/phrase being discussed.
If you just want to know the meaning of a word, try OneLook Dictionary Search first.
