Thinking computationally. This is not thinking like a computer as they do not think and cannot think ad it isn't even programming.
Thinking computationally simply enables you to work out exactly what to tell a computer to do.
For example, if you go somewhere that you have never been before, you will probably plan out a route of how to get there before you go out. You might compare different routes and see which is best, this might be which is shortest or has the best roads. Once planned the route you would go to your destination step by step.,
In this case, the planning of the route would be thinking computationally and the following of the directions would be the programming.
Being able to turn a complex problem into one that can be easily understood is a skill that is extremely useful.
