Behaviourism

According to John B. Watson, Behaviourism is a theory that points out that second language acquisition takes place through the habit formation and it is acquired by means of stimulus and response in the form of mechanical repetition.

USES

• You can use this theory to find out the most effective stimulus to provocate a secod language acquisition.
• The linguistics enviroment plays and important role then you can use many images, tools through repetition.
• You can use  class management through the reinforcement to reward the students efforts or punishment to dicrease undesirable behavior.
• This theory focuses on speaking and pronuntiation more than writing because is based on repeating sentences. 

Drawbacks 

The video shows us how the Behaviourist Theory ignores completely  the inborn aspect of human knowledge because the students only repeat what the teacher says.

The theory puts more  emphasis on the role of imitation and ignores completely the creativity of the child, making him/her somewhat passive viewer than actor in the process of language acquisition.
