The 80/80 Challenge

This is a simple, honest challenge for any teacher, anywhere. All you have to do is select a subject/topic you are comfortable with and think you teach well. After teaching it, design a test that you are sure 80% of your students could achieve an 80% score on. Give the test and examine your results.  If the results surprise you (your students don't do as well as you thought), redesign the test and keep giving it until you get the desired result. This is not an activity for a teacher who has nothing left to learn.  And if the results are a bit depressing, consider the alternative - continuing on, unaware of the true situation in your class. Of course, this brings all sorts of discussions into play about ability, testing, the proper way to measure learning, etc.  Try it, let us know what happens...............
