Today's podcast goes deep on the experimental problem from the 2016 exam. Digressions include:
* How many readers we needed to grade this problem
* Why and how this problem promotes creative lab work in your class
* NOT giving your students a lab sheet
* The difference between a "plausible plan" and a "detailed procedure"
* How to write, and to teach students to write, a lab procedure for the AP exam
Here's the link. As always, feedback is welcome. Email me or post a comment, and I'll address it in the next episode.
Tech pointer: someone mentioned having difficulty downloading a previous episode. These are all shared via google drive. They seem to work fine for me on either an iphone, an ipad, or a computer. (I haven't tested on a non-apple mobile device.) I did once have my phone say "file not found"; but if I told it to "open link in new window", everything worked fine. It worked so fine that it wouldn't shut up when I opened my music app, and I had to pause the podcast manually. :-)
