Michael Lerner

@cossettej I am printing this out and putting it on my desk.

@lernerphysics I could say the same thing about meeting @lernerphysics 😀 You are such an excellent model of how to use inclusive humor to push norms and challenge others to explore outside of their comfort zone. Many memorable quotes from this conference but among them is "normalize leaving!!"

It was an amazing opportunity to speak at #AAPTSM24 and one that I won't soon forget 😊 What an incredible week of talking physics and turning online friends into real-world friends!

This camp helped me meet so many great physics teachers and made me feel like I had something worthwhile to share. Incredible professional development. #modphys #iteachphysics

If you want to join a community of physics teachers & realize how much you can contribute, sign up. Presenting at AAPT made me *feel* like a physics teacher who belongs & is valued. Even if you're not sure what you'd present, sign up. Mentors can help you think through it.

This is such a good idea, @Jleescience! I think if you want to know what you can learn at something like #AAPTSM23, this is the thread to read.

@msruggerio @BarnettDreyfuss @NCNAAPT It's a my-fault thing mostly. I suggested it as a topic for a session. I'm now just crawling out of my shell to publicize it.

@msruggerio @BarnettDreyfuss @NCNAAPT Tell them to contact me! I'm running a "Long Time Listener, First Time Caller" Session that designed for 4 new HIGH SCHOOL presenters to have coaching and encouragement to present at AAPT. I can get them in after the deadline!

@maalmeida85 @TeachWright @MrJoeMilliano In the "Arrange" menu for GraphSketcher, there's an "Add Jitter" command. You can plot the ideal points and have the computer make them a little bit off--or a lot more, if you add jitter more than once.

Today I'm advocating for you to include data points w/ scatter when creating graphs for student worksheets and assessments, especially early in the school year #iteachphysics

@SecaurPhysics @MartaStoeckel @hoffmanscience @maalmeida85 Using energy to solve projectiles problems is AMAZING and allows students to see connections. Using projectiles to practice kinematics is falling into the trap of doing too much kinematics in physics class.

Do any #modphys teachers cover free fall later on w/ 2DM or different models? I've been doing it with CAPM for years and may switch it up this year. Just wondering what others have done? Go physics!

@mrmalvikscience Since I have some students who take AP1 and AP2 concurrently, I do ray optics->wave optics then heat-> gases->fluids, then electric circuits->electrostatics->capacitors->magnetism->photons->modern physics. DM if you want some packets.

I’m teaching AP 2 for the first time. #iteachphysics #modphys I’m looking for any help you can provide with scope and sequence or resources you use often. TIA

@TigerPhysics @PickPhysics Do you have an editable version for people who like it but want to tweak it?

@helenrey @DeltaGPhys @PickPhysics and I typed up this mindset reading to discuss with students at the start of the year drive.google.com/file/d/156Wy9f…

Always relevant. Might include this at the start of the year...

@MissStrunk In 1997, I was actively recruited to be a physics teacher in a large school district. In a second-round interview, I came out. All communication from them stopped. I called back, made the head of HR very uncomfortable by asking questions, but didn't get the job.

Have you personally ever declined a job or chose not to apply for a job because you felt some part of your identity (race, ethnicity, sexual orientation...) made the location of the job unsafe for you?

Great difference in students’ descriptions of HS and college instructors. #AAPTSM22

@RealMrSkyWalker My go-to, which may not be the best: an *unbalanced* force causes a change in momentum. If you get hit from both sides at the same time with the same strength, your momentum won't change. Same for Fg & Fn in this case. (Also--N2L is just conservation of momentum.)

Reasoning around mv conservation in a standard physics class for the first time in a while. How do you help them work out when an interaction diagram shows a system interacting externally, yet its momentum doesn't change? @lernerphysics #iteachphysics #modphys

@elana_gloger C'mon now--you weren't in high school that long ago.

Interviewing participants for a longitudinal NIH study sometimes leaves me speechless. A participant recently chose to drop out b/c of their health. When recording this, I noticed their start date was when I was still in high school. I am a 5th year PhD candidate now. Wild.

I like playing with Web VPython. I think this simulation will help answer the question "When is the wire long enough to call it infinite? trinket.io/glowscript/210…

@MCDphysteach So thank you for helping me make my first step into Google Apps Scripts. I'm a newbie too, but your question helped me make my first step. I hope my answer helps! 5/n

@MCDphysteach And then, I went to the original spreadsheet, and now I can use =percentdiff(a1,b1)! It was simple, but it was also magic. 4/5

Who do I need to bribe at Google to convince them to include percent error and percent difference as functions in excel so I don't have to type =to_percent(abs(x-y)/average(x,y)) a million times?
