Tool: Citation Murder Board

One of the things I'm glad of in the UCCS library classrooms is the whiteboard wall. While it occasionally bothers me when an arrow I've drawn on one slide that then gets in the way of the next one, but the sheer amount of whiteboard space is great for getting students involved in library instruction.
In particular, the whiteboard wall really works for teaching citation mapping (or ancestry searching or citation chaining...). One way I've seen this done in the past is to work it into the Google Form library worksheet, but one of my colleagues here does something different that I like a lot. She hands out slips of paper with bitlys to various articles and has students work in groups to skim the article and put up a few pieces of key information on the board. She then has them literally draw connections between the articles to show how they live in conversation. This requires a lot of prep work, but it leads to some great discussions about how scholarly conversations evolve. 
In one of my first solo ENGL 1410 (think freshman writing), I opted to rework this slightly to eliminate the slips of paper. The class had a sound studies focus, so I chose articles about the impact of noise on the body:

What Worked: 
Students got really excited about showing which articles dealt with similar topics and which dealt with very different topics. They started to think about how they might group them in an argument, which wasn't on my agenda but which was great conversation.
What Didn't: 
The class had a bit of trouble seeing the links between who cited whom in our array of articles.
What I Want to Do Differently Next Time: 
I might cut down on the number of articles used. I definitely want two examples by the same author, one example that's cited by more than one other example, and one example that is cited by another and cites another. 
I also want to have the students tell the class their article title, author, and publication date before putting them up on the board. I think that will address some of the issues around seeing who cites whom and organizing the articles by date to spark conversation about currency.
