What benefits are there to giving students the power to decide their math futures as a sophmore?
Students have a better idea of what they want to do with their lives in high school. If a student decides they are not interested in a STEM career, there may be no need to take Calculus. Instead, they can focus their time and energy on classes that help their future degree/career.
It gives students more options in their math classes: Statistics, AP Statistics, and Personal Finance are great course offerings that are not on the Precalculus → Calculus track. In most careers, and in life, these three courses are more valuable and useful than Calculus.
When students accelerate in middle school, they miss math topics that are not talked about again in their K-12 mathematical career. By accelerating in their junior year, they are exposed to all foundational math skills and do not end up with the “holes” in the knowledge that we typically see with students who have been accelerated past an entire year of content.
