how to think computationally
How to Think Computationally
  • Jeannette Wing’s CACM article, 3/2006
jeannette s grand vision
Jeannette’s Grand Vision
  • Computational Thinking will be a fundamental skill used by everyone in the world by the middle of the 21st Century.
    • Just like reading, writing, and arithmetic.
    • Incestuous: Computing and computers will enable the spread of computational thinking.
    • In research: scientists, engineers, …, historians, artists
    • In education: K-12 students and teachers, undergrads, …
computing is the a utomation of a bstractions
Abstractions

Automation

Computing is the Automation of Abstractions

1. Machine

2. Human

3. Human + Machine

4. Networks of 1, 2, or 3

Computational Thinking is the process of abstraction - choosing the right abstractions - operating in terms of multiple layers of abstraction simultaneously - defining the relationships the between layers

as in Mathematics

guided by the following concerns…

Jeannette M. Wing

measures of a good abstraction in c t
Measures of a “Good” Abstraction in C.T.

as in Engineering

NEW

  • Efficiency
    • How fast?
    • How much space?
    • How much power?
  • Correctness
    • Does it do the right thing?
      • Does the program compute the right answer?
    • Does it do anything?
      • Does the program eventually produce an answer? [Halting Problem]
  • -ilities
    • Simplicity and elegance
    • Usability
    • Modifiability
    • Maintainability
    • Cost

And, identifying and sharing appropriate abstractions to help students to develop the ability to abstract

challenges 1
Challenges - 1
  • Convincing CS faculty/departments of the importance of teaching CS courses for non-majors
  • Creating several such courses for students with different needs/interests
  • Convincing other departments as to the importance of CT, and helping them to incorporate CT into others of their courses
challenges 2
Challenges - 2

We have lots of courses that have shown to be successful individually, but how do we scale them?
