Curriculum in Califormia

A nicely comprehensive article late last year outlines the plans for the next overhaul of school mathematics curriculum in California -- delaying any algebra until high school, cutting and compressing later classes to fit the reduced time, disposing of gifted & talented or accelerated programs, de-tracking, etc. As usual, the motivation for this to hopefully see higher pass rates from the easier courses, claim to better support inequalities among minorities, be better positioned for well-paying STEM college programs and careers, etc. Among the fonts of battle are particularly academic math professors vs. math-education faculty, who are generally on opposing sides of the issue. 

One thing that really stuck out to me was the case of one student, who's held out as being the one black student throughout her advanced math courses in school, and currently studying as a math major at UC Berkley. Here's how her story is presented: 

Mariah Rose, a third-year applied math major at UC Berkeley, said she didn’t have another Black classmate in any of her math classes until this semester.

“There’s one other Black student in my class right now, and that’s just crazy to me,” said Rose. “The number of Black and Brown people in math is so low.”

Rose, who is half Black and half Latino, said this is nothing new. She said she was the only Black female student in her advanced math classes during high school. And her successes in math make her an outlier in California’s public school system where Black and Latino students score lower on standardized tests...

Rose, the UC Berkeley math major, said she has mixed feelings. She agrees with the framework’s recommendation to delay more advanced math classes and avoid labeling students based on their math abilities at younger ages. But she isn’t sure if she would be where she is if she hadn’t been accelerated into a higher-level math class in 6th grade. 

“It was a game changer,” she said. “I don’t know if I would’ve pursued math if I hadn’t advanced so early.”

Proofs and Applications

This is a quote that lives rent-free in my head, and comes up a lot in discussions I participate in.

From Stein/Barcellos, Calculus and Analytic Geometry, 5E, "To the Instructor", p. xxii (1992):

At the Tulane conference on "Lean and Lively Calculus" in 1986 we heard the engineers say, "Teach the concepts. We'll take care of the applications." Steve Whitaker, in the engineering department at Davis, advised us, "Emphasize proofs, because the ideas that go into the proofs are often the ideas that go into the applications." Oddly, mathematicians suggest that we emphasize applications, and the applied people suggest that we emphasize concepts. We have tried to strike a reasonable balance that gives the instructor flexibility to move in either direction.
