@ThePTSOS @kilroi22 @NCNAAPT Scott was my colleague at Carlmont HS and it's great to see his legacy continuing with PTSOS.

Dan @kilroi22 sharing some history about Scott Chan, local @NCNAAPT member and physics teacher whose memorial fund is reimbursing workshop registration fees for attendees today.

There would be a lot of issues if 1 was prime.

Really interesting survey data. Social media seems to fall into the "everything in moderation" category of risky behaviors, yet it's blamed for so much of the mental health epidemic among teens.

Here's a new glimpse into where EDU is headed. #gpt4 youtu.be/rnIgnS8Susg

@Anna_D12 @DanJRich @DWalkerdine @Inner_Drive @EvidenceInEdu @m_chiles @adamboxer1 I don’t think it’s helpful to think of _a_ formative or _a_ summative assessment, since the same assessment data can be used formatively or summatively. To me, the terms make more sense as descriptions of the conclusions we draw from the assessment outcomes.

women don't want flowers, they want a unified theory of gravity and quantum mechanics

@Dean_of_math It takes a while, but it's kind of amazing when students eventually realize this is your intent (though some never seem to escape feeling victimized by assessment.)

Assessment isn’t something we do to students, it’s something we do with and for students.

@physicsramble This student is applying calculus of a single variable, in one dimension, to a problem that is two dimensional.

@fnoschese @DrDavidBoyce @Desmos @gnuphysics Whoa nPlot is amazing

@DrDavidBoyce @Desmos Desmos is great! Also check out nPlot by @gnuphysics: noragulfa.com/nPlot/ Its a bit more science-friendly for making graphs.

Since I went paperless in my classroom I have found digital graph drawing difficult. Differences with graph drawing software can make a class with BYOD inconsistently successful. Just tried @Desmos. It works the same on every device and the graphs look great. #iteachphysics

If Twitter crashes and you need to find me, the hell you will. I've got a two day head start on you, which is more than I need. I speak a dozen languages, know every local custom, I'll blend in, disappear, you'll never see me again.

Note to self: next year devote an entire day of the circular motion unit to describing and analyzing everything in this video. ⛸️ Sidenote: it's totally ok to show "Christmas Eve on Sesame Street" as long as it is after Halloween 😏 #iteachphysics

Self-care routines and bear encounters both start with setting boundaries

@MsMagaryPhysics @helenrey @SJDJ This is cool! I use her Physics books all the time, didn't know there were Earths science probes too

@helenrey @SJDJ There’s also a Page Keeley book with some probes: uncoveringstudentideas.org/books/formativ…

Interested to hear from people who address climate change in the physics classroom and how you do it. Specifically age/knowledge/what they apply that knowledge to/ how you know they can... theguardian.com/environment/20…

@helenrey I like having 10-12 grade students read and discuss a factsheet on local climate impacts, then play the EPA's "Generate: A Game of Energy Choices" and finally write a position paper applying their knowledge. epa.gov/climate-resear…

@bravesearth If you have the equipment, here's the station rotation lab with intro and follow-up that I just finished today: docs.google.com/document/d/1n8…

@bp_ellis Oh I like that! I have been looking for ways to add in more e&m

Do I want to start my freshman off with constant velocity, balanced forces, or energy? Another decision I can't seem to make today. Anyone have strong opinions one way or the other? #modphys #iteachphysics

@bravesearth The concept that magnetic potential energy can be transferred to electric potential energy and vice versa. HS-PS3-5 using energy bar charts as models. Start simple by modeling magnets attracting, pie tins repelling off Van de Graaf, then move up to generators & electromagnets.

@bp_ellis What electricity and magnetism concepts do you work in?
