User:Steven Gomez/Project:Expression Representation Variability.11

How do people with different background/training communicate ideas?

Spatial Concepts

• Assembly instructions, or how simple mechanical devices work
  • Doorknob
  • Ballpoint pen (e.g., how ink rubs on on the papers and the ball is "re-inked" by gravity)
• Maps
  • Drawing a map from Brown CIT down to Kennedy Plaza from memory -- what do subjects include?

Non-spatial (or, not observable) Concepts

• Chemical processes
  • Acid + Base = Water + Salt
  • Rust/Oxidation

• Astronomical processes
  • Greenhouse gas build up
  • Albedo -- light absorption/reflection
  • How a cell phone calls another cell phone

• Computational processes
  • Explaining concurrency, race conditions, deadlocks
  • Explaining inductive proofs to non-math people
  • Explaining the 'map' function (i.e., for all elements, or numbers, in a set apply some function to get a new set)
  • Describe a traffic light "state machine" based on a set of written observations
