Abstract:
|
Interactive computer
visualizations have been coupled with hands-on experiences to create a
series of activities which help students learn about waves in quantum
mechanics. The goal of the materials is to enable secondary students and
non-science college students to obtain a qualitative understanding of
the wave nature of matter. Included in the instructional materials are
student-centered activities that address why we use waves to describe
matter, how we interpret the matter waves, and why accepting a wave
model of matter leads to quantization and the uncertainty principle.
Applications of quantum physics to atoms, the electron microscope and
the Star Trek Transporter are included. Throughout the instructional
unit, which is part of the Visual Quantum Mechanics project, the
students work with interactive visualizations rather than equations.
Thus, the mathematical prerequisites are low and allow students with no
background in calculus to begin to understand the implications and
interpretations of quantum physics. |
