WHO?
Who stands behind the information? Your entry should identify (quickly and concisely) the background/credentials that connect the article’s author/s to the
WHAT?
Identify a claim (or claims) presented in the article that is relevant to your inquiry. (Remember, your task is not to summarize the entire article, but to summarize the article content that is relevant for your own inquiry. In some cases, of course, the entire article may be directly relevant to your project.)
HOW?
How is the claim supported? How do the authors back up the claim? (Don’t go nuts here and summarize every detail of the methodology. Instead, strive for the kind of concise, general summary one might find in a news account of recent research findings.)
SO WHAT?
What is the relevance of the claim for your inquiry? (Sometimes you’ll be able to express the “what” and “so what” at the same time, in which case you shouldn’t try to artificially separate them. Just make sure that your paragraph addresses all of the categories–WHO, WHAT, HOW, and SO WHAT? And remember that your answer to the “so what?” question should point to your own research inquiry.)
