Problem   Solu+on  

Lectures  take  too  long  to  prepare  and  are  too  1ring  to  give  

Let  the  students  explain  things  to  each  other  

Explaining  how  molecules  behave  is  too  hard  

Let  simula1ons  do  the  work  (show,  don’t  tell)  

I  explain  the  same  thing  over  and  over  again  

Record  it  once  

My  students  think  “algebra”  is  a  some  sort  of  underwear  made  of  seaweed  

Let  soEware  do  the  tedious  work  

Wri1ng  and  grading  homework  takes  too  much  1me  

Put  it  on  the  web  

Tools  for  the  lazy  teacher  

or    How  to  use  sarcasm  to  convince  teachers  to  use  new  tools
