The thing fundamentally wrong about this is that it gives the kid all the power and forces the teacher to work around misbehaving and deliberately abusing-the-system students.
Part of the grade is getting assignments done when they are due. Learning certain things in a certain amount of time. Because these are skills that you need to do work and get tasks done in certain periods of time. Showing up to class or work on time when expected. Doing work or studying during designated times.
It’s putting the insane in charge of the asylum. Kids needs an external authority that gives structure. Not this crap.
Any math experts out here? If so, I need help understanding this.
SBG and Marzano depend on the “Power Law” as a non-linear function that emphasizes trending versus averaging because averaging isn’t fair. “The average of scores penalizes the student for not knowing anything at the beginning of a unit. The average score will artificially drag down a student’s score.”
Power function:
RT = aP-b + c Exponential function:
RT = ae-b(P-1) + c Where
RT = Trial Completion TimeP = Trial Number, starting from 1 (for exponential functions the P-1 argument is used)a, b, and c, are constants
I find it very interesting that the “Power Law” (law… as in a proven constant i.e. Newton’s law…) itself is called into question due to the use of AVERAGING.

“However, subsequent research by Heathcote, Brown, and Mewhort (2000) suggests that the power function observed in learning curves that are averaged across participants is an artifact of aggregation. Heathcote et al. suggest that individual-level data is better fit by an exponential function and the authors demonstrate that the multiple exponential curves will average to produce a curve that is misleadingly well fit by a power function.”

“The power function is treated as the law relating response time to practice trials. However, the evidence for a power law is flawed, because it is based on averaged data.”
