The Dynamics of Variability in Introductory Physics Students' Thinking: Examples from Kinematics

Source: ComPADRE - Resources and Services for Physics Education

UG and PG | Career/Technical Study

eng

Physics education research has long emphasized the need for physics instruction to address students' existing intuitions about the physical world as an integral part of learning physics. Researchers, however, have not reached a consensus-view concerning the nature of this intuitive knowledge or the specific role that it does (or might) play in physics learning. This dissertation contributes to ongoing inquiry into the nature of students' intuitive thought and its role in learning physics through... View more

Author: Engelhardt, Larry

UG and PG | Career/Technical Study

eng

The Magnetic Resonance of Spin One-Half Particles model simulates the magnetic resonance of a spin ½ particle. Users can vary the frequency of an oscillating magnetic field and see how the quantum spin responds. Users can also vary the magnitude of both the oscillating field and a static field to observe how this affects the resonance.The phenomenon of magnetic resonance is of practical importance, and the equations that describe magnetic resonance can be derived with relative ease. For t... View more
