John Evans on 21 Feb 16"omputational thinking is one of the core objectives that runs through the computing program of study in England from Key Stage 1 to Key Stage 4. Before computers can be used to solve a problem, computational thinking refers to understanding the problem itself and the ways in which it could be resolved. Software engineers and computer scientists for example, routinely engage in computational thinking. As a higher order thinking skill, computational thinking has applications both across and beyond the school curriculum. There are four key techniques to computational thinking: Abstraction - focusing on the important information only, ignoring irrelevant details Algorithms - developing a step-by-step solution to the problem Decomposition - breaking down the problem into smaller, more manageable parts Logic - looking for similarities among and within problems Learning to program is one of the best ways to develop computational thinking, as it uses each one of these techniques. My intention here is to show an example of a lesson in which computational thinking is taught at Key Stage 1 (5 to 7 years) through programming. I took the lesson plan (attached above) from The Barefoot Computing Project and I taught it to my 1st grade class last week. It required the children to work in pairs to create step-by-step instructions through pictures. The pairs then swapped each other's instructions, which they used to draw the 'crazy character' that the other child had in mind."
