Body Control Center
Rating

The amount of monitoring and adjusting that goes on in the human body at any given time is astounding. In this interactive feature every change in activity requires you to make adjustments in respiration or heart rate or energy delivery, and an adjustment to one system often changes the balance in some other system. See if you can do as good a job maintaining the harmony in this virtual body as your nervous system does in you.

Common Sense Concepts of Motion
Rating

Common sense (CS) misconceptions are not arbitrary or trivial. Indeed, every one of the misconceptions about motion common among students today was seriously advocated by leading intellectuals in pre-Newtonian times. If the evaluation of CS was so difficult for the intellectual giants from Aristotle to Galileo, we should not be surprised it is a problem for ordinary students today. Accordingly, common sense beliefs should be treated with genuine respect by instructors and regarded as serious alternative hypotheses to be evaluated by scientific procedures. A taxonomy of common sense concepts which conflict with Newton s laws is presented. Elementary teachers who are aware of these CS beliefs can teach deliberately to avoid contributing to student development of misconceptions.
