I taught in an independent school several years ago and convinced the board to offer a 2-year Algebra 2 class. We made 4 years of math a requirement and preached to the students and parents to take math during the fall of their freshman year in college. Not surprisingly, the results were impressive. Many of the weaker math students used to take a watered down algebra 2 as high school juniors, skip math as seniors and then eventually fail math in college. Students coming out of the 2-year Algebra 2 course sailed through their college math requirement. Whether we are discussing a 2-year Algebra 1 for students who arrive in High School without the skills needed to be successful or a 2-year Algebra 2 for student on their way to college, the moral of the story is the same: "One size does not fit all." Once we decide to focus on the needs of the students rather than trying to impose certain outcomes on all, then we will have a reasonable common goal.
