Dares for the 21st Century Teacher

I dare ya to...
...teach math without using "x" and "y"
...throw out all of your worksheets
...let students decide what's important to learn in history class
...teach English without assignments of "write a paper"
...(for high school teachers) do activities that you get from Elementary school teachers
...make your students say more than you do during a class period
...let your students design the science experiment
...never give a student the correct answer
...design an activity where every student generates a unique product
...let your kids use their cell phones to learn
...teach Geometry(high school) using Euclid's "The Elements"
...let your students pick what they want to read
...not assign homework
...have students research a topic strictly through Twitter
...involve creative writing in every topic of your course
...let kids decide if they need a desk or not
...never teach the same lesson twice
...teach phys ed. using nothing but multimedia
