The idea
One working rhythm for computational thinking runs in three phases: abstraction formulates the problem, automation expresses the solution, and analysis executes and evaluates it.
In practice
A commuter models the route options, scripts the daily choice, then checks a month of results.
Where people slip
Skipping analysis leaves the solution unexamined.
