A VERY PUBLIC EDUCATION: California’s Math Misadventure Is About to Go National.
When I decided to read every word of California’s 1,000-page proposal to transform math education in public schools, I learned that even speculative and unproved ideas can end up as official instructional policy. In 2021, the state released a draft of the California Mathematics Framework, whose authors were promising to open up new pathways into science and tech careers for students who might otherwise be left behind. At the time, news reports highlighted features of the CMF that struck me as dubious. That draft explicitly promoted the San Francisco Unified School District’s policy of banishing Algebra I from middle school—a policy grounded in the belief that teaching the subject only in high school would give all students the same opportunities for future success. The document also made a broad presumption that tweaking the content and timing of the math curriculum, rather than more effective teaching of the existing one, was the best way to fix achievement gaps among demographic groups. Unfortunately, the sheer size of the sprawling document discouraged serious public scrutiny.
I am a professional mathematician, a graduate of the public schools of a middle-class community in New York, and the son of a high-school math teacher. I have been the director of undergraduate studies in math at Stanford University for a decade. When California released a revised draft of the math framework last year, I decided someone should read the whole thing, so I dove in. Sometimes, as I pored over the CMF, I could scarcely believe what I was reading. The document cited research that hadn’t been peer-reviewed; justified sweeping generalizations by referencing small, tightly focused studies or even unrelated research; and described some papers as reaching nearly the opposite conclusions from what they actually say.
The document tried hard to convince readers that it was based on a serious reading of neuroscience research. The first chapter, for example, cited two articles to claim that “the highest achieving people have more interconnected brains,” implying that this has something to do with learning math. But neither paper says anything about math education.
The CMF is meant only to guide local districts, but in practice it influences the choices they make about what and how to teach. Even so, the version ultimately adopted by the State Board of Education is likely to distort math instruction for years to come. Armed with trendy buzzwords and false promises of greater equity, California is promoting an approach to math instruction that’s likely to reduce opportunities for disadvantaged students—in the state and wherever else educators follow the state’s lead.
If there’s a better argument in favor of local control of education — or homeschooling — I’ve never heard it.
