IMO a part of it is the parents wanting change and something “better”. The basic ways of teaching math, reading etc shouldn’t need to change. It worked for generation upon generation. Now they need to come up with “new” ways to teach it because it needs to be “better”.
I’m also of the belief that open enrollment has been a huge detriment to our education system. Schools are now more worried about having lots of shiny new toys and college level athletic facilities to draw in kids/parents fro.. outside their district because more kids equals more money. Schools need to go back to being block buildings with basic classrooms. They don’t need top flight weight rooms, padded indoor tracks, flat screen tvs every 20 feet etc.
I also would like to see numbers from pre COVID for these same districts.
