Computational Thinking

Thinking Ahead
1. Identify inputs and outputs
2. Determine preconditions for solving problem
3. What parts of the program can you reuse?
4. Benefits and drawbacks of using cache memory
Thinking Logically
1. Identifying points where a decision is made
2. Logical conditions that determine outcome
3. How decisions affect flow of program
  1. If...Then...Else
  2. While, For loops
  3. Switch case
Thinking Procedurally
1. Problem decomposition
2. Identifying components of solution
3. Determining the order of steps needed
4. Use of hierarchy charts or class diagrams
Thinking Abstractly
1. Any computer model is an abstraction
2. What properties to take in to account
3. Removing unnecessary details
4. Examples: London Underground map
Thinking Concurrently
1. Which tasks can be tackled at same time
2. Benefits and trade-offs of this
  1. Increased throughput
  2. Time wasted waiting spent on another task
  3. Programs could take longer to complete
