# Data science vs. calculus

California's proposed math guidelines claim to promote equity by offering a data-science alternative to the traditional algebra-to-calculus track. The State Board of Education delayed approval after critics charged it would lure disadvantaged students off the track to STEM success.

In an *Education Next* forum on math education, University of Chicago economists Steven Levitt and Jeffrey Severts argue for teaching data literacy to all students, while Boaz Barak, a Harvard computer science professor, and Adrian Mims of The Calculus Project make the case for advanced algebra and calculus.

Levitt and Severts propose streamlining algebra and geometry, which now take three years, so all students have time to "learn how to analyze, interpret, and visualize data."

We could teach them the difference between correlation and causation. And perhaps most importantly, we could help them understand the limits of data, so they would know when to be skeptical of data-based claims.

Data skills should be taught early, so they can be applied in students' other courses, they argue.

They oppose a separate data-science track, arguing it's not a lesser, easier option for students who'd struggle in advanced algebra, trig or pre-calculus.

A high school data-science class will be a superficial introduction to "data literacy," not an "equitable alternative to calculus," Barak and Mims write. It will not close academic gaps. It will -- if students never go on to calculus -- close the door to STEM futures.

Far from being relics from the “Sputnik era,” calculus and algebra are more important than ever in K–12 education.

. . . The field of data science builds on mathematics, statistics, and computer science, and a thorough data-science education requires foundations in all three fields. For this reason, taking advanced math courses (algebra II, precalculus, and calculus) is a much better preparation than high-school data science,even for students who are interested in data-science careers.

"Closing education gaps requires improved teacher recruitment, training, and retention," they argue. Without excellent math teachers, curricular changes will do little good.

Moreover, creating “data-science pathways” as alternatives to the standard pathway can and will have a particularly harmful impact on disadvantaged students. Such pathways emphasize proficiency with computational tools such as spreadsheets over the mathematical concepts (functions, equations, symbolic manipulation, and logical reasoning) that are crucial prerequisites for more advanced math and that also build the type of thinking needed for coding. Hence, in practice, data-science pathways will become lower tracks by another name.

Educated, tech-savvy parents will steer their children toward the traditional math track, they predict. Not all parents will understand the trade-offs.
