Re: [Phys-L] [**External**] Re: NGSS and kinematics



Frankly I am more concerned that they don’t appreciate the challenge presented by the many misconceptions the students gave about describing motion and role force. I doubt they know about the flu

The NGSS are a disaster, especially considering the huge fraction of people
teaching physics who are supposed to be following these standards (but
basically have the most rudimentary - at best - understanding of physics).
It's so disheartening.

Curious about this NGSS as it is semi-foreign to me since I teach in a
private school. Is it just about motion, forces, energy, and waves? Who
developed/refined these standards?

I just read JD’s analysis of the NGSS and as a high school physics

I have one question: “Did the lights just flicker?”

No kidding, earlier today I was going about an assigned task: identify
the
NGSS standards measured on one of my tests. The topic? Vectors.

I offer my condolences.

and I noted that there is nothing about kinematics in NGSS.

I agree with the sentiment. I would say there is "almost" nothing
about kinematics.

*) Newton's second law is barely mentioned:

-- Mentioned in passing in the middle-school section on page 51:
https://www.nextgenscience.org/sites/default/files/AllDCI.pdf#page=51

-- Mentioned in passing in the preamble to the HS section on page 75:
https://www.nextgenscience.org/sites/default/files/AllDCI.pdf#page=75

-- Mentioned in a nontrivial way on page 79:
https://www.nextgenscience.org/sites/default/files/AllDCI.pdf#page=79

*) Conservation of momentum is mentioned twice (and wrongly expressed
both times).

*) There is a treeeemendous emphasis on "stability". An earlier draft
defined what they meant by that, which was utter nonsense. The final
draft simply removed the definition, leaving us with a heavy emphasis
on a term that is undefined and unexplained.
