| Title | CD's, DVD's & Optical Commmunication: Binary Coding and Diffraction Errors |
| Description | This in-class work (ICW) is used in a university non-math "How Things Work" course (replacing the lecture). It is designed to accompany section 15.2 in Bloomfield's text (3rd ed). It uses the "Wave Interference" simulation, but the first half of the activity covers binary numbers and information coding in Cd's/DVD's (adapted from the "Computer Science Unplugged" program at the University of Canterbury. New Zealand). Contact me for solutions. (Note, you may want to change page 2 where I ask students to determine my baby's due date and my birthday.... it was good motivation for them that day!) |

I like how you started the activity with dice because students can relate to them. This gives students a good place to build on prior knowledge.
