tough to say for most of us. i know talking to people who i know who teach they talk about the amount of time during a period, a semester, a year that gets eaten up by a variety for a variety of reasons and not just teaching something such as crt
the other challenge that has gotten bigger and bigger i am told is the lack of help from home in terms of making sure kids are getting their work done, parents being involved, etc...
Obviously the issue is complex, but there's definitely a culture problem.
I taught at an after school program for a bit at a middle school in Fort Worth, and you knew which kids you couldn't discipline because the parents were a bigger problem than the kids.
There was a 7th grader that I'm almost positive was dealing drugs (and I know stole my wallet), and the parents attitude when you called was always, "Why are you wasting my time?"
I went to a poorer public school (I believe 50% were on free or reduced lunch), but we had IB and AP classes. Even though those classes were open to everyone, the vast majority of my classmates were white. When I took non-AP classes that everyone had to take, a good portion of the regular students never paid attention.
I don't know what the answer is, but it's hard to help someone who won't help themselves.
