One aspect that I got pulled up on after my first LSA on the DELTA was my drilling ability. I suppose it was fair enough considering that I just wasn't doing any before. I used to think drilling was a waste of time and I felt silly getting my students to repeat the same sentences or phrases over and over again. I know now that it is a vital part of teaching English. Students need to practise their pronunciation repeatedly so that they can transfer the language to memory.
Okay, that might be a bit extreme, but I love doing drilling now and have a lot of fun doing it. I also feel a lot less self conscious, especially in front of the older teenagers and adults. If you're looking to improve your drilling techniques then check out this list of resources below:
There's a good article on An ELT notebook by Lee Shutler as he covers various aspects of drilling. Lee covers the benefits and variations which include the direct approach, silent drill, and communicative drilling. 3)Teaching Techniques - Drilling
