Computational Thinking Exemplar 10

Exemplar 10, Progress outcome 4, Parity Bit Magic
 Prior to the task:
Students will have discussed and/or participated in activities in the following areas:
  • computers store and transmit data using patterns of binary digits, or bits 
  • the importance of accuracy in storage and retrieval of data
  • some of the consequences of incorrect data storage or transmission in their daily lives
  • errors are detected by computers e.g'.check digits on bar codes.
Students will have also participated in the "Parity Magic trick" (see below)
The Task:
Students work in pairs to respond to three questions to demonstrate their understanding of how to detect and fix computer errors using parity bits. They are required to:
• explain what can go wrong when a computer is saving or sending files
• explain why a computer needs to know if there is a problem and give examples of what can happen if it can’t detect errors
• demonstrate how a computer uses parity bits to detect errors.
See the exemplar for examples of student responses
Parity Magic Trick
​Use cards that are black on one side and white on the other or you can use this website (see the 'Card Flip Magic' video below for instructions).
To see how the trick works watch CS Unplugged Part 3 video or see the instructions here  or here.
