Why student evaluations of teaching are worthless “The paper compared the student evaluations of a particular professor to another measure of teacher quality: how those students performed in a subsequent course. In other words, if I have Dr. Muccio in Microeconomics I, what’s my grade next year in Macroeconomics II?Here’s what he found. The better the professors were, as measured by their students’ grades in later classes, the lower their ratings from students.” “This class should start an hour later in the morning. Also, theteacher shouldn’t wear sandals.” This NPR article summarizes a new study that tackles a problem that […]
As if he were making art just for my interests, Nate Milton presents this animated short film, “TANK”.

Whew, I’ve been away from the blog for a bit while I finished my PhD candidacy. Now that I’ve been deemed a competent scientist by my senior colleagues, I have a backlog of blog posts to get to. I’m going to start by pointing you towards Science Studio, a collection of the best science multimedia on the web. This idea comes from Rose Eveleth and Ben Lillie, who are two people behind the equally excellent podcast Story Collider. So, why is Science Studio cool? Well, finding really good science media isn’t easy. Unfortunately, the best and most effective science multimedia isn’t […]
Charismatic animal? Check.Neat gadgets? Check.A revealing look into something previously un-observable? Check.Oh boy, we’ve got ourselves a Nature paper brewing. Credit to Martin Heigan (left) and Richard Ashurst (right) A study published in the journal Nature led by Dr. Alan Wilson shines a light on why the way cheetahs move is so interesting. By using collars with some very fancy devices that measure how the animals change speed and direction, the research team showed that even though cheetahs are the fastest land animal on Earth, their ability to stop is what really catches dinner.The collared cheetahs displayed some of the […]
Check out this great video from MinuteEarth that compares the dynamics of plant communities to the economics of beer. Sounds strange at first, but ends up being a great way to explain the importance of biodiversity to an economics major who is taking there required biology course. Check it out: Make sure to take a look at MinuteEarth’s other videos on youtube and connect with them on Facebook and Twitter.
