Creswell has a very straightforward and easy to understand style. He takes different aspects of research and looks at them from the perspective of the five methodologies, making it very easy to determine which ones seem most appropriate for the research being considered, and why. I found it very readable, which meant I learned more about methodologies I am not currently considering, just because it was interesting and I kept on reading. His presentation of published papers and then discussion also helps to put things in context, in a way theory just can't! For those starting to explore the differences in approach, as I was, this is a very good and helpful book.
