Melanie Jaspers book, Beginning Reflective Practice is a good book to get. It goes through many reflective cycles that you can use and is really easy to understand.
It is my bible when writing reflective essays. I have to admit that I don't find writing them easy, but I have just recieved an essay back and got a good mark with it.
The book shop on here may sell a copy, but I know it isn't an exspensive book to buy.
