Force Schemas and Energy Bar Diagrams:
Two Powerful Tools for Physics Teaching
Glen Wagner
Centre Wellington District High School

This workshop will introduce to participants a way of giving thinking
tools to their students in two important areas of learning: 1)
constructing free-body diagrams and, (2) tracking energy flow when solving
conservation of energy problems. Since implementing these tools in my
classroom many of my previous stumbling blocks to problem solving have all
but disappeared. Participiants will be given numerous examples to work
through to show the value of these tools as well as published references
for these ideas.
