Sam Evans and Karin Kirk: climate change

Sam and Karin shared with us approaches and resources to use when talking about climate change with physics students. Sam talked about how he’s used climate as the context for introducing energy, indicating that his students were much more engaged. Karin shared her work with the CLEAN web site, which provides a searchable array of resources for teachers.

Here’s the recording.

We’re taking the next two weeks off. Happy Holidays, or, as my 7 year old has decided we should say: Cock-A-Doodle-Doo!

Bethany Wilcox and Danny Caballero: Math framework

Bethany and Danny talked with us about a framework they’ve developed to help assess how students in upper divisions physics courses use math. We talked about how hard it can be for an expert problem solver to articulate all the steps used, but that for a novice, it’s important to be able to see those. They shared different ways of posing questions to get students to use various tools. An example would be “Use Taylor’s series to . . .” vs “What is an approximation to the result around x= . . .”

Here’s the recording

This week (12/18) we’ll be talking about ways to teach about climate change with Sam Evans and Karin Kirk. Join us!

Student capstones

We spoke with eight different students about five different projects. They were on sliding cups, parallel springs, slingshot trajectories, hockey slap shots, and rotating chains. It was so great to hear them talk not only about their content and what they learned, but also about how a project helps them think about physics and science in general.

Here’s the recording.

This week (12/11 at 9:30pm ET) we’ll be talking with Bethany Wilcox about an upper-division math framework she’s been helping develop for physics major courses. Please join us!

Error Propagation

We talked about ways to teach error propagation, spending a fair amount of time bashing the significant figures approach. John Denker, the author of the article you were encouraged to read, joined us and has since updated the document in response to the great discussion.

Here’s the recording.

We’re now taking a two week break. We’ll be back on 12/4 with student capstone presentations. If you have any students who you think could give a short (5-10) minute presentation on a project of theirs, please let Andy ( know.

Steve Maier: Oklahoma ToPPS program

Steve shared with us the work he’s done to support Oklahoma physics K-12 education. The ToPPS program he works on runs summer institutes and is famous for mailing classroom sets of whiteboards to every public school physics teacher in the state.

Here’s the recording.

This week: CANCELLED! We’ll push the book club conversation about error propagation to next week (11/13). Here’s the link for the reading.

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!

Kris Shaffer: GitHub for academics

Kris showed us how he uses GitHub to work collaboratively with colleagues and students on many different types of documents. He talked about hosting web pages on GitHub and using it as a platform for online texts.

Here’s the recording.

This week:
We don’t have a guest scheduled this week. We have 2 options:
1. Take a week off
2. Talk about a topic of interest to you
