Don’t know how many of the fellow associates who were in the tutorial the other day will actually find this, but the conversation came up about finding useful pictures and graphs for demonstrating how to read graphs, etc to students. You might want to be a bit careful about some of these, because some of them are a little bit looser than others on the conventions of graph writing, and the majority of the sites flit between being “acceptable” for the classroom and decidedly unacceptable, so I’d also be careful of not recommending too many of these sites to your students.
With the disclaimers out of the way though: here’s some of the best places I’ve found:
Be very careful not to recommend this one to your students, but it’s got some fantastic stuff mixed in with some very very nerdy stuff and some jokes that are downright crass. Don’t worry if you don’t understand lots of the jokes there: it just means you have a life.
This is a much safer site to recommend: though at times it can get slightly political (can’t we all), Information is Beautiful has an incredible collection of infographics which can communicate complex information usually in simple, easy to understand ways. My wife is a graphic designer and she is in love with this site.
This is a much less definitive recommendation: graphjam’s stuff is all about user-contribution so the quality varies from putrid to fantastic. But if you do manage to get a hold of the good ones, they are usually pretty cool/funny. The whole thing is graphs and Venn diagrams, so you should at least be able to find something useful if you look long enough. They’re certainly not as pretty though.
Indexed is a fantastic little blog I’ve been following for ages: the cute hand-drawn Venn diagrams and graphs are always good for a laugh.
Hope these have been helpful. If nothing else they’ve helped me to procrastinate a little more rather than working properly on my lesson planning assignments.
