From the article:
No assignment can be docked points for lateness as long as it's turned in by the last day of the quarter...
Yes, that will prepare them for the real world, where everyone is free to ignore deadlines...in fact, I hear they're been renamed "alivelines" to better represent the fact they're of no importance.
This is also grossly unfair to teachers; as it is I'm always rushed by students asking if they can turn in missed/late work in the last week or two of a grading period. And those grades are DUE at a specific time and place, the teachers won't have this "deadlines don't really mean anything" fantasy-world they're putting these kids in.
...and any quiz or test can be retaken for a better grade throughout the term.
There will be no way to know if that "D" was just a fluke from a good student or if it's some low-level kid who kept guessing at the answers until they got a passing grade. Grade inflation is already rampant in this country; if this is the path we're going, why even bother with grades at this point? This is going to take them from "inflated" to "meaningless" in no time.
Changes in education are proof that there's a sucker born every minute.
