this video in which he talks about search strategies. Today, I read another of Dan Russell's blog posts that I think many teachers and students can benefit from reading.
In Internet Search: What makes it simple, difficult, or impossible? Dan Russell explains what can make searches difficult, common search mistakes, and strategies for better searches. I read Dan's article and have to admit that I am sometimes guilty of falling into the trap of the "framing effect" that he describes. Breaking out the "framing effect" will improve my search methods and I'm sure it will for you too.
