1. Computational Thinking/CE21/CSPrinciples 1 What is Computational Thinking? Owen Astrachan

2. Computational Thinking/CE21/CSPrinciples 2 What is Computational Thinking? l Potter Stewart, 1984, Jacobellis v Ohio  I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description of [computational thinking]; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it,

3. Computational Thinking/CE21/CSPrinciples 3 Computational Thinking l Leverages the power of computing l Has the potential to scale, to process lots of data l Accessible to lots of people with varied backgrounds l Not just about metaphors, but about facilitating doing things:  Computational Doing

4. Computational Thinking/CE21/CSPrinciples 4 Computational Thinking Practices l Part of the CS Principles project/course  Practices associated with evidence centered design  Content X Practices = claims and evidence l Seven Big Ideas, Six CT Practices  See by example what we will use to develop assessments

5. Computational Thinking/CE21/CSPrinciples 5 URL for CS Principles documents l http://bit.ly/csthinking http://bit.ly/csthinking  What is bit.ly?  Where is bit.ly mostly used?  What does http://bit.ly/f2eAHN referencehttp://bit.ly/f2eAHN  What about http://bit.ly/f2eAHN+http://bit.ly/f2eAHN l Is this computational thinking?

6. Computational Thinking/CE21/CSPrinciples 6 Inculcate Computational Thinking l Not done solely by computer scientists l Not done solely by college professors l Not done without lots and lots of funding l Not done without lots and lots of education l Harambee

7. Computational Thinking/CE21/CSPrinciples 7 l Ladder from ‘white’ to ‘house’  White, while, whale, shale, … l I can do that… optimally  My brother was an English major  My ladder is 16, his is 15, how? l The key is sough  Voila, 14 words! l Guarantee optimality! A Computational Thinking Story

8. Computational Thinking/CE21/CSPrinciples 8 Finding Computational Thinking l If I ever go looking for my heart's desire again, I won't look any further than my own back yard. Dorothy to the Tinman
