Using Language appropriately for a range of classroom functions

Learning a new language can be difficult  if we don't know the purpose of the language. So, for that 

it's really important to know the classroom functions.

When talking about functions, these are varied and they can be useful by instructing. Furthermore, 

functions have different exponents which can be used in the classroom. Of course, the use of the 

exponents will depend on the purpose and the context. The content, the teacher should include will 

be based on getting learner's attention. The topics should be according to students' needs in order to

 make students gain confidence about their abilities. So, for that teachers should be clear at the 

moment to give instructions (instructing).

What's more, modeling language orally can be really helpful because students can repeat only what

 the teacher wants them to learn.
