"Is Algebra Necessary?", the title of a piece by Andrew Hacker (an Emeritus Professor at Queens University) in a recent issue of the Sunday New York Times is the topic this Friday. It came to my attention because Hacker briefly quotes me in the piece. Hacker argues that the algebra requirement for all high school students is misguided. Hacker's view is hardly new, but it raised quite a bit of traffic in the blogosphere.

This talk investigates students' work on a problem where they developed their understandings of rates of change through group work on a problem.  Anna will show examples of classroom conversations that display students' transitions towards a deeper understanding of rates of change.
