Computational Thinking

 What is computational thinking?

Computers can be used to help us solve problems. However, before a problem can be tackled, the problem itself and the ways in which it could be solved need to be understood.

Computational thinking allows us to do this.

Computational thinking allows us to take a complex problem, understand what the problem is and develop possible solutions. We can then present these solutions in a way that a computer, a human, or both, can understand.

The four cornerstones of computational thinking

There are four key techniques (cornerstones) to computational thinking:

  • decomposition – breaking down a complex problem or system into smaller, more manageable parts
  • pattern recognition – looking for similarities among and within problems
  • abstraction – focusing on the important information only, ignoring irrelevant detail
  • algorithms – developing a step-by-step solution to the problem, or the rules to follow to solve the problem

Each cornerstone is as important as the others. They are like legs on a table – if one leg is missing, the table will probably collapse. Correctly applying all four techniques will help when programming a computer.  (More information HERE  )

Barefoot Computing is a great FREE resource , and the resources are mapped to Curriculum for Excellence and the current Experience and Outcomes. The materials provide learning opportunities to support aspects of the broad general education Computing Science curriculum within the Technologies whilst also providing interdisciplinary experiences across the curriculum.

Barefoot add Logic and Evaluation as key concepts, but you will see the Computational Thinking concepts and approaches could be used anywhere in the curriculum.

Registration for Barefoot resources is FREE and you can even book a free CLPL twilight at your school for all the teachers.

Full information is on the site, and I would encourage you to explore and make use of the many ready to use in CfE lesson plans.
