Kevin Boehnke from the University of Michigan explains how he approaches scientific papers:
"I always start with title and abstract. That tells me whether or not it’s an article I’m interested in and whether I’ll actually be able to understand it—both scientifically and linguistically. I then read the introduction so that I can understand the question being framed, and jump right to the figures and tables so I can get a feel for the data. I then read the discussion to get an idea of how the paper fits into the general body of knowledge."
