Inverse Functions: What Our Teachers Didn’t Tell Us was the engaging cover article of the March 2011 Mathematics Teacher journal written by the author team. The article was identified as an Editor and Panel Pick for Summer 2011.  Editor Albert Goetz wrote, “This article took a topic that is very difficult to teach and hard for students to understand and made it just the opposite: easy to teach and crystal clear for students.” The article may be previewed here: http://www.nctm.org/eresources/toc.asp?journal_id=2&Issue_id=972.

 

Motivating Change

Posted: April 2, 2011 in Journal Articles

Change is difficult even when it’s the right thing to do.  Our cover article for the March 2011 Mathematics Teacher journal titled Inverse Functions: What Our Teachers Didn’t Tell Us has generated diverse responses such as these:

  • a thoughtful approach on turning inverses inside out
  • I will be changing my emphasis and notation ASAP!
  • I am appalled that they would teach this

Our article challenges a traditional way for teaching inverse functions – the switch x and y approach. We instead advocate for the solve for the dependent variable approach and point out the problems caused by the commonly accepted switch x and y approach.
