PPP: this stand for presentation, practice and production and is similar to the straight arrows kind of described above. In PPP classes or sequences , the teacher presents the context and situation for the language ( e.g. describing a robot) ,and both explains and demonstrates the meaning and form of the new language.The students then practice making sentences with can and can’t before going on to the production stage in which they talk more freely about themselves or other people in the real world. As with straight arrows lessons, PPP is extremely effective for teaching simple language at lower levels. It becomes less appropriate when students already know a lot of language , and therefore don’t need the same kind of marked presentation. A typical example of a basic PPP procedure is given in chapter 6.
