Lesson details

Key learning points

  1. Boolean expressions give results that can be used in selection and iteration.
  2. Boolean logic is used in selection to test conditions.
  3. Complex decisions can be constructed with Boolean expressions.

Keywords

  • Boolean operator - an operator used in a Boolean expression, for example AND, OR and NOT

  • Logical operator - another name for a Boolean operator

  • Program flow - the order in which the instructions in a program are executed

Common misconception

Boolean logic is only used in logic circuits and logic gates.

The three fundamental Boolean operators are AND, OR and NOT. These are used in programs to perform selection and control program flow. In Python, these are written in words as: and, or, not.

Boolean statements are based on human language and can be articulated to understand when they are true. Expanding such statements into full sentences can help pupils appreciate how they are evaluated so that specific syntax of the programming language does not become a barrier to understanding.
