Is a True/False Test Rigorous?

I'm having a great day just outside of Houston.  I love seeing teachers when they realize that they are already incorporating many aspects of rigor in their classrooms, and increasing rigor doesn't mean throwing everything away...it just means adjusting some of what you are doing.  For example, you may use true-false tests in your classroom.  Although I prefer some other options, I never tell teachers to get rid of those tests.  If you want to use one, great.  Just adapt it.  Instead of students choosing to write T or F or that wonderful letter they hope we will interpret to be the correct answer, add one more step.  If an item is false, rewrite it as a true statement.  That simple step makes any true-false test more rigorous!
