I started HS in AUG, 1977. They didn't offer Algebra I until freshman year. I took the equivalent of Pre-Algebra in 8th grade. They didn't offer a Calculus class until after I graduated HS. I took the equivalent of Pre-Calculus as a Senior at the end of Trigonometery. I went on to take three semesters of College level (5 credit hour) Calculus courses, Differential Equations, Linear/Matrix Algelbra, Numerical Methods, and a host of other Physics and electronic circuit theory courses that went beyond the math in my Calculus courses. I did alright without formally taking Algebra I in 8th grade.
A move away from Algebra I in 8th grade would appear to be a step backward.
My son is in 7th grade Pre-Algebra and will be taking Algebra I next year in the 8th grade. He has an old Dad compared to most of his classmates.
My brother-in-law is a PhD Physics professor over in IL. He has complained for several years that the students coming into college don't have the math skills needed for higher science classes.
