I am currently doing an online TEFL course. And one of the questions is about error correction.<br/><br/>I was just wondering if anyone had any advice on how to correct this error -<br/><br/>'Good morning, sir. What's up?' (Intermediate)<br/><br/>I know this is a mix of formal and informal speech but I'm just not sure how you would encourage the student to self-correct immediately.<br/><br/>Any help would be greatly appreciated, thanks.<br/><br/>Grebs
