Development of computer generated animations

By using the design program 3d-Studio-Max a series of short videos in mpg format about different topics of physics have been developed. The flexibility of computer graphics in form of continuous transitions, virtial trips and motivating visualizations are used to support difficult learning tasks.

• List of annotated Video-files
• (pdf-Format)
• (html-Format)

Development of short videos to support activities in physics classes

• Role-playing game about the so-called Simple Electric Circuit
Experimental demonstration of surface charges
• Demonstration of a syringe model in action
• Experimental demonstration
  of a retarded current in an electric circuit
• Various experimments about electrostatics
• Videos, showing electric fields around charged particles moving at high speed
  (in agreement with Lorentz transformation)

Evaluation of learning material in respect to motivation and understanding

• Results of a test about Force and Motion" , administered by members of the ColoS group in 1999/2000
• Results of a test about Basic concepts in mechanics", administered by members of the ColoS group in 1999/2000
• Computer supported course material about ,Inertial mass - Gravitational mass".
