Distinguish between programming and computational thinking.
Computational thinking helps the user write better algorithms, whereas programming helps the user design better computers.
Computational thinking tells a computer what to accomplish, whereas programming allows the user to work out what to instruct the computer to accomplish.
Programming tells a computer what to accomplish, whereas computational thinking allows the user to work out what to instruct the computer to accomplish.
Programming tells a computer what to accomplish, whereas computational thinking allows the user to write in a programming language.
