Showing vs. Telling

This week Bill and Janette address the question, what is the difference between showing and telling.  Developing writers are often in the habit of "telling" their readers, meaning they will state their conclusions without effectively demonstrating to their reader how they arrived at that conclusion.  Sometimes this may be an issue with assuming the reader is already familiar with the subject and other times it may be because the writer is unsure of how to explain how they arrived at their conclusions.
