Some interesting discussions about velocity and articles

We had some great verbal discussion about velocity today.  What I thought were straight-forward homework questions turned out to present some deep conceptual misunderstandings.  We explored the definitions of displacement, velocity, and what the average in average velocity really means.  We began to play with carts accelerating down ramps.

Some parents wanted to know more about what we are doing and why, so I have posted the two recent papers we published last year.  One articles was presented at ASEE (American Society of Engineering Education) conference and the other at the IEEE conference.   These articles are rather technical so I will post some non-technical articles soon.
