From Computing to Computational Thinking

Book description

This easy-to-understand guidebook gives you the tools for understanding and using Computational Thinking (CT). It does not assume experience or knowledge of programming or of a programming language, but explains concepts and methods for CT with clarity and depth. Puzzles, games, and everyday examples provide starting points for discussion and for connecting abstract thinking patterns to real-life situations. The book lays an interesting and thought-provoking path to gaining general knowledge about modern computing and the concepts and thinking processes underlying modern digital technologies.
