Adrienne Traxler: Modeling and C-LASS

Adrienne shared the data and analyses presented in this paper. We talked about the difficulty of achieving positive C-LASS results (from pre- to post-test), and we talked about how the Modeling curriculum seems to help with that.

Here’s the recording.

This week (10/30) we’ll be talking with Steve Maier about work he’s done to support physics teachers in Oklahoma. One cool thing he did to whet your appetite was to mail each public school teacher in OK a classroom set of whiteboards. Very cool.

The week after that, we’ll hold a pseudo book-club on this older article from John Denker about ways to do error propagation. It’s very negative about using “sig figs” and that has been a topic of conversation on twitter lately.

After that we have a lot of openings, so we’re looking for people who want to share for ~15 minutes on a cool teaching tool/issue/topic. Contact Andy ( if you’re interested.

Lynne Raschke: math prep vs conceptual performance

Lynne has researched correlations between students’ math preparation and performance on various types of assessments in a conceptual physics course at St. Scholastica. She talked to us about her methodology and results, which suggested two intriguing but nearly opposite suggestions for changes in the future.

Here’s the recording.

This week (10/23) we’ll be talking with Adrienne Traxler about “Extending positive C-LASS results across multiple instructors and multiple classes of Modeling Instruction.” Join us!

Richard Piccioni: energy focus for modern physics

Richard shared how he has focused on teaching about energy transfer and conservation in his Physics First curriculum. He talked about efforts to better prepare students for chemistry in their next class. He showed us the charts he uses and even had us take a crack at solving some of them. Here are his slides.

Here’s the recording.

This week (10/16) we’ll be talking with Lynne Raschke about student math background success in conceptual physics courses. Join us!

Supporting a physics educator culture

We talked about ways that we could build a more supportive and vibrant community of physics educators. We compared and contrasted ourselves with the Math Twitter Blog-o-sphere (MTBoS) and we talked about ways to re-energize local meetings of aapt groups.

Here’s the recording.

This week (Wednesday 10/9) we’ll be talking with Richard Piccioni about qualitative analysis of energy changes and transfers. Join us!
