Physics 11 – A couple of oops in the pictures above… First, the dreaded twisted slinky.  This is annoying but I sort of get why it can happen. The quiz however is much harder to understand.  What is it about my teaching which allows even one student to have such little understanding to make the mistakes shown above?  Sometimes teaching can be frustrating. It’s a constant puzzle to figure out what went wrong. I guess this is the intellectual challenge that keeps it interesting.
