It’s a waste of time to retake pre-algebra many times until all the kids in the class can get it (and many never do). 30 math problems 2 years below you would take about 10 minutes. So, I am not sure if I mind the wasted time doing easy problems, it is more that many kids can and SHOULD take calculus in high school. Skilled math students can start thinking in math terms which opens up physics and other math based ideas to them.
It’s a waste of time to not learn critical reading, thinking and writing skills because you are in a silly social studies class with everyone all mixed together. You can teach college level english classes with high level reading assignments and discussion periods in high school, or you can drone on about basic grammer rules and read collections of insipid short stories. You can understand history in perspective and say co-go-po comparitive government and politics, or you can memorize facts … You need teachers who will grade essays to college level, which probably will be difficult if some of them are barely able to write a legible sentence at all.
Science classes can either be the beginning of a love affair with science and nature or a meaningless drone.
I think there is certainly a place for high level education for 15-18 year olds that we want to be the future politicians, scientists, journalists, historians, mathematicians, hey even app developers. If we have to hire some PhDs to teach in high school, hey, I hear there are some out there, and if you put them in a classroom with really smart high schoolers and pay them say 70K a year with summers off, I think you may have something there. The issue is that no one wants to pay a teacher 70K because we think they all should be graduates of schools with 500-500-500 SATs and earn 50K (numbers made up here).
Most kids will not need tutoring if they really should be taking 12 AP classes in high school … but some people want to make their snowflake even more special and will pay lots of people to help (and in fairness, if english is not your first language or if you haven’t taken anything beyond college algebra … .a tutor probably is necessary if snowflake hits any obstacle in their path …).
Maybe this is an issue with school choice … let people chose to go to say TJ or to go to a very good traditional high school or a tiger-mom AP factory or maybe an arts program.
NJ has a unique town-based education system (most states run their schools on a county level) so maybe some of this is being pushed by concentrations of affluence, ambition, even ethnic differences … good and bad.
I don’t think memorizing facts would get you a 5 on any of the harder AP tests. If memorizing facts is the basis of an AP class, I think scores will be very disappointing.
Stupid homework is stupid … but math problem sets are easy if you are good at math … essays are quicker to write if you write a lot and learn to organize your thoughts … reading is easier if you learn to read quickly and critically … etc.
