Transcriptions

For advanced students or those of you who feel your English is pretty good but you just need a little bit of 'touching up'. transcribing a recording, exactly word for word, mistake for mistake is a very good way of finding out what type of grammar and pronunciation errors you are making.
It goes without saying that you must be exact in your transcriptions otherwise the exercise is useless.

1. Record yourself or your student talking about their research or a project at work.
2.  Listen bit by bit and transcribe exactly how it is spoken. 
3. Listen again 2 or three times to make sure you have everything exact.
4. Go through together and do an error analysis and offer suggestions or invite the student to correct.
5. Write out the passage corrrectly and the student or you read and record again

The following text is writtten word for word with pronunciation errors as well.
