Oh my, I read your first link in its entirety and, "Yikes."
The Public comment #5 section regarding chapter 12 (which covers homework and assessments) was especially shocking.
Chapter 12 in the 2005 version of the CMF was 5 pages long. The same chapter in the current draft is 70 pages long, almost entirely due to a slew of opinions against homework and other testing practices.
The entire CMF draft was (and still is even after corrections) littered with improper citations that at times entirely contradict the opinion it's meant to support.
I find it the height of irony that a group of educators arguing against homework appear to have... not done their homework.
This brings to the forefront a concern I haven't seen mentioned much in this thread: let's put aside how such a policy might affect any particular student's performance in school... what kind of adults will this policy create?
Imo, policy like this will create adults who put in about as much effort into their work as the 20 people employed to oversee this iteration of the CMF. A single professor did their work for them, and even with his help they still haven't fixed it.
"Oh, you got an F on your assignment? No problem! Just turn it in again next week and I'll give you an A."
To be clear, the specific policy I just mentioned really is part of the document - allowing students to always redo work for a better grade.
That reinforces that idea that it's okay to do a half-ass job because you can always "fix it later". In the real world however, poor decisions can have devastating effects the very first time, and there might not be a chance for a "do-over".
Homework also normalizes the idea that things will be expected from you in this world if you are to be employed. It's not only about engaging with the material, it's also about practicing being a hard-working and fastidious human. Our grandparents might have said that doing homework "builds character", and I would agree with them.
Finally, the idea presented by the CMF draft that homework just isn't very useful is absolutely wrong. Case in point, piano practice. The only way to get better at playing the piano is to practice. The difference between someone who pokes around on the keyboard every blue moon and someone who practices daily is stark.
Some might argue that becoming proficient at playing a piano is inherently different than becoming proficient at math, to those folks I would ask: How is training muscle memory and engaging with new material so different between the two?
