The struggle is real! 4/€1,00 grocery store croissants in Netherlands this summer confused me for a solid minute.

My grading is a weird mix of in and out of Canvas, digital and not. This “spreadsheet” is saving my tuchus.

When the globe is removed, will the scale reading, go up, down, or stay the same? Great test of Newton’s 3rd. #ITeachPhysics #teach180 days 34 & 37
This was part of the balanced forces lab practical on Tues. We revisited it on Fri for families-visit-class day.

#ITeachPhysics After too many hours of troubleshooting, I give you The Monkey and the Zookeeper...with a Twist: our monkey has a parachute. The zookeeper needs to deliver a banana to feed the monkey on the fall.

Oh interesting. I was trying to get the forces to balance. Would you draw the force diagram on the right?

#ITeachPhysics, do you use interaction diagrams (aka system schema) to help students identify interaction pairs? They've never sat well with me because students mistakenly try to apply directional meaning. I give you my modification: the Interaction List. How else are we formalizing ID'ing forces?

Doing the hover puck lab, I finally hit upon language that improves student outcomes, "as smoothly as possible." I still need to work on directions for making a sharp left turn because I want them to see that they need to hit at ~45° to the direction of travel.

Day 3: Accel Algebra and Precalc is 2 courses in 1, meant to propel a select batch of juniors into calculus for senior year. We use cognitive science, explicit practice on study skills, and standards based grading to get them there. Stus take a quiz every. single. day, starting now. #teach180

Day 2: Physics 2 solved Ramp vs. Turntable as an introduction to circular motion. I wanted to see them working on a problem, reviewing their physics, and working with lab equipment. These observations help me set an initial level for this new course. #teach180

Aug 27 was year 22, day 1. Intro classes for Physics 1 (9th gr), Physics 2 (new course), and accelerated Precalc.
Physics 2 opened class by trying to time releasing a marble down a track to hit an X on a rotating disk. #teach180 #iTeachPhysics

Teaching a new course this year that stretches my content knowledge and pedagogical expertise. I’m honored for the opportunity and nervous about the many opportunities to have either exposed.
This is my 22nd year teaching; it’s been a decade since I felt this raw. Tell me something to help?

The Design of Everyday Things by Don Norman may be the design bible for human computer interaction but teachers can take an important lesson from it on errors. Norman says there are 2 types of error, how & when they happen, and how to prevent them. 1/

Grrr, my least favorite verb! Friends don't let friends use a more complicated word when a simpler one will do. I can't think of a case where "utilize" gives more detail than "use."

Which I notice is sqrt(2), exactly what the mathematicians would say! I didn't know that exactly 1 cm has infinite sig figs. Cool!
My lack of respect for sig figs ruined my cheeky question. How about this?

Aha, yes I do recall that! So, if I'm measuring 3.05cm on that one ruler, I'd write x=3.05cm? As in, the value is exact, not approximate.
Follow up question: How would you express the length of the diagonal of this square?

Fair! I've taught a lot of 9th grade physics where we avoid math complexity, so I'm out of practice. But, many of my former math stus will be physics 2 stus next yr, so when writing a solution to generate problem-solving tips, I had to confront the issue.
Constants are definitely coming!

Mostly meant tongue-in-cheek.
In math, I teach that approximation requires ≈
In physics: Nearly all solutions are =
This problem I just wrote is making me question how we think about equality in science vs math. I hear you on using sig figs -- this may be just the nuance I needed. Thanks!

So much to unpack is right!
Only now that I'm seeing the same students in both contexts do I have to actually confront it.
My specific context is this problem where the final answer is an approximation. In physics context, I've always written F_f=0.003 N. In math, I'd use ≈. What would you use?

You using MacGyvered is 🤌!
If I thought I could aim the ball well, I'd use the magnet "plate" type accessory to get a flat surface.
I believe the force probe end of your Go Direct cart accepts a 4-40 screw. What about a plate with a countersunk hole and a 4-40 countersunk flat screw?
