What are the main principles of structural linguistics?

1) language is not learned by repeating after a model

2) the teacher takes what they say into consideration and works with the students to help them overcome negative feelings which might otherwise interfere with their learning

3) the original and principal reality is not an isolated fact of a given language, but rather the language as a system

4) students must give the teacher their attention in order not to miss what he says.

5) students  should be  engaged in a great deal of meaningful practice without repetition
