If you're looking for a book to get you into the wonderful world of TEFL teaching, this is a very good place to start. It covers all the basics, and has enough detail that seasoned teachers can still get use from it. For years, along with Jeremy Harmer's book, it has been well known as an authoritative text on teaching English, and for good reason. However, unlike Harmer's book, it is surprisingly difficult to find in High Street bookshops. So without being able to see inside both, how do you choose which one to buy?
Personally, I prefer Scrivener because the page layout isn't as dense as in Harmer. The font is a little lighter/thinner, and the paragraphs seem shorter, and to me, this makes the information in the book seem easier to absorb. I feel able to dip into Scrivener and pick out information quickly. I realise this is a bit of a flimsy reason to recommend this book, but when you're faced with having to choose one of the TEFL methodology staples and you can't see inside (unless the publishers enable this on Amazon, or you're lucky enough to find a High Street bookshop that has both Scrivener and Harmer in stock), I think this is worth knowing. Both books have excellent content, but I found Scrivener a pleasure to read. And that's basically what you want in a book, isn't it?
