Jekyll for clicker questions

For a few years, I’ve been a fan of clickers (aka personal response systems) for large lecture sections. Clickers are a simple–and scalable–way to incorporate a little widespread active learning in the classroom. They can’t work miracles, but they do allow me to reward attendance, rouse the students once in a while, and give good feedback to all of us about how well the latest concepts are sinking in. I like the accountability: If you got the question wrong when 80% of the class got it right, that’s on you, but if 20% of the class got it right, that’s on me.

Length of papers

Nick Trefethen has posted a wonderful graph showing how the average length of papers published in several SIAM journals has doubled over the last 40 years.
