UNIT 29 CATEGORISING LEARNERS MISTAKES

     First all of , it is very remarkable to mention the difference between error and slip. Error a mistake that students do when they trying to use a range of language more than their level of knowledge and Slip a mistake that students that they can solve by themselves.L1 interference influences on the students development. But mistakes result in problems of accuracy. What kinds of mistakes do learnes make?
there are inaccuracy: pronunciation (it means incorrect pronunciation of a word or words),inaccuracy: grammatical (incorrect verb form ),inappropriate style (register), lexical (incorrect adjective),spelling (plural for example), and punctuation (inaccurate use of full stop).
Also, there are oral and writing mistakes, but over here the most important part is to help students to avoid these kind od mistakes. They want to use the correct form of the language to communicate with suitable context and clear message.
As a conclusion, we can categorise learners' mistakes in accuracy and appropriacy.
