  • Taking the mission seriously

    Earlier this year I tried to figure out whether I had a common mission in all the math classes that I teach. Here’s what I eventually came up with: To empower all students to represent the world quantitatively and to… Read More ›

  • Turning back the clock

    By on

    One of the many virtues of writing in a wiki is that previous versions of a document are always readily available. I’m still trying to get used to this. Want to turn the clock back to the way your document… Read More ›

  • The Murder Room

  • A billion is a substantial number

    By on

  • George Bush, student of English

    One of my students is having great difficulty understanding the abstract ideas of additive and multiplicative inverses and identities, especially in the context of matrix algebra. Finally he’s so frustrated that he exclaims, “I feel like George Bush in an… Read More ›

  • Wiki values & learning curves

    By on

    Why am I finding it so difficult to get used to be a writer on a wiki, not merely a reader? There’s something about the whole process that still feels alien to me. Somehow the learning curve seems unnecessarily steep…. Read More ›
