Support in the lesson
Correction is very important in English lessons. It is the main advantage of practising English with the support of a teacher. Error correction does not normally occur when simply chatting outside of English lessons. Correction from one a learner’s friends or colleagues is very rare. It is often unhelpful or incorrect. Most people believe it is rude or inappropriate in a social situation.
Every English course
Correction is the rightful occupation of a language teacher. It helps learners learn faster. Correction helps learners avoid developing fossilised errors that they cannot “unlearn.” All types of English courses, including General English, Conversation and Cambridge exam preparation courses (IELTS, CAE, FCE, etc) require correction.
