Writing Summary, Research, and Theory/Comment papers?

I have to write a Summary, Research, and Theory/Comment paper over 3 different articles for my Social Problems (Sociology) class. I did not keep my Intro. to Sociology book, and I am not having any luck searching for how to do these papers. Does anyone have any advice?

I know the format, font size, etc… I am just not positive on how I am supposed to write each paper. Thanks!
