Key message

Not all information is trustworthy, and some sources of information are intended to mislead or confuse people. For this reason, it is important that children and young people have the critical thinking skill to analyse information and evaluate its authenticity.

Critical thinking does not mean criticising people or ideas. Critical thinking is an important skill in an information rich world that helps children and young people examine new pieces of information in order to make an informed judgement on an issue (Young and eSafe, Office of the eSafety Commissioner 2018).

Developing critical thinking skills

Children and young people should always consider and question the relevance, accuracy and reliability of any content they find online. Peter Ellerton (Lecturer in Critical Thinking, The University of Queensland) suggests that students need to master 4 key concepts to develop their critical thinking abilities:

  • Argumentation – the process of intellectual engagement with an issue and opponent with the intention of developing a justified position.
  • Logic – the rules of deduction and induction used to proceed from premises or evidence to conclusion.
  • Psychology – an awareness of how our minds actually work, especially the effect of cognitive biases and prior beliefs.
  • The nature of science – knowledge of basic statistics and the difference between hypothesis, theory and law.
