Jeannette M. Wing describes “computational thinking” in this PDF:
Consider these everyday examples: When your daughter goes to school in the morning, she puts in her backpack the things she needs for the day; that’s prefetching and caching. When your son loses his mittens, you suggest he retrace his steps; that’s backtracking. At what point do you stop renting skis and buy yourself a pair?; that’s online algorithms. Which line do you stand in at the supermarket?; that’s performance modeling for multi-server systems. Why does your telephone still work during a power outage?; that’s independence of failure and redundancy in design. How do Completely Automated Public Turing Test(s) to Tell Computers and Humans Apart, or CAPTCHAs, authenticate humans?; that’s exploiting the difficulty of solving hard AI problems to foil computing agents.Computational thinking will have become ingrained in everyone’s lives when words like algorithm and precondition are part of everyone’s vocabulary; when nondeterminism and garbage collection take on the meanings used by computer scientists; and when trees are drawn upside down.
But wait — didn’t you just say we’re using “computational thinking” already, even without the fancy vocabulary? And when you express the desire that the language of computational thinking enter the general public’s word-hoard, aren’t you forgetting that much of the terminology of computation was itself borrowed from everyday life? Children were “backtracking” for their mittens — and hikers to discover missed forks in their paths — long before there were computers.Also, what’s the difference between computational thinking and, well, thinking?(Wing’s essay accessed from here.)
