Computational Thinking

Computational Thinking

1. Decomposition

   • The act of taking a problem and breaking it down into smaller more manageable parts.
   • Solving a crime: Who where when why?

2. Abstraction

   • The act of removing unnecessary details from a problem to simplify it.
   • E.g The London Underground map. Do not need to know the speed of the train or type of train, just how to get there.

3. Pattern Recognition

   • The process of identifying repeated elements to avoid solving the same problem more than once.
   • Move up (2) Move down (3) etc.

4. Algorithms

   • A set of step by step instructions to solve a problem.
   • Abstructured english algorithm uses short, structured sentences to express the instructions.
   • Flowcharts
     • A flow chart is a type of diagram that can be used for an algorithm.
     • It is made up of arrows and the shapes, terminator, process, decision.
