IANA educator in any sense of the word. My nearby niece/daughter-in-law is an elementary teacher in a fancy-pants suburb. She’s a young, professional, enthusiastic, and idealistic kid-centric teacher. IOW, part of the solution, not part of the problem.
In the 2 previous school years she taught Kindergarten in a well-endowed public school. Online, and half in person / half online. Which was an unholy mess. When half of what you’re teaching in the first 5 months is simply how to attend school, sit still, hold a pencil, and behave in a group, well, … that’s damn hard over Zoom.
The current school year she’s teaching first grade at a fatcat Christian but non-Catholic parochial school in the same city, but some miles distant from her old school. So her current charges are the output of last year’s kindergarten when she was teaching that grade. Not the same kids, but kids from the same SES, scholastic, & COVID environment
Her anecodotal report is the first 3 months of first grade are basically redoing what didn’t happen in kindergarten because the total curriculum & testing demands on progress to be made simply were unobtainable versus the COVID-driven obstacles.
So now at the end of first grade the kids are less behind than they were at the start of first grade, but still well behind where they “belong” at the end of first grade. Setting aside the kids who get discouraged and spiral in, she figures by 4th grade we might have caught the typical kids up to pre-COVID normality. If nothing else goes wrong in the next 3 years.
FWIW, she also supports @Left_Hand_of_Dorkness’s contention that standardized tests, and the inevitable bureaucratic reaction to them (“teach the test; nothing else matters! (to our budget and management promotions).”) is more harmful than helpful.
I personally have no useful opinion, but I can share what I’ve been told by somebody whose expertise and POV I trust. It’s anecdote, but IMO it’s worthwhile anecdote.
If this is what happens when Dad’s a lawyer or exec & Mom is a SAHM with a Master’s degree, I have to imagine the situation is orders of magnitude worse where Dad drives a truck plus Uber & Mom works a cash register and waits tables.
