Why use dictations in class

          Using dictations as a language learning device has been neglected in our country in recent years. Though a lot of teachers and students consider dictations dull, time-consuming, non-communicative and pointless, I believe that, when not used too often, they can be beneficial for the students.  
         What are some of the advantages of dictations: they improve listening skills and the ability to distinguish sounds; improve spelling and raise grammatical awareness; improve the ability to guess words from context; improve concentration and develop short-term memory; involve all students in the class and prevent bad discipline; get students acquainted with interesting texts.
