Computational thinking skills and principles of
computer programming


Computational thinking skills

Effective computer programming depends on the computational
thinking ability being practised by you. These skills can allow you to
analyse a problem, methodically analyse it, and find possible
solutions that can be further developed into a functional software
program.




The picture was taken from the Programming unit 4 BTEC L3 book.




Decomposition
The first step of computational thinking begins with decomposition,
which is breaking down complex problems into simpler, more
achievable pieces. Issues that appear doubting at first and become
even more manageable with decomposition.
