Dr. Sandra Gibson produced a video a few years ago, based on her study-skills work with thousands of students at Georgia State University. The video was, and is, used by hundreds of colleges across the country.
Recently she has rewritten the accompanying book (to update for the digital world and the issue of digital distraction). It's a practical guide, from someone who knows both students and study skills.
Unfortunately, it's only available as a Kindle book at this time, but the good side of that is that it's less than five dollars.

Good luck. We need more smart liberal-arts students!
