Have you ever tried asking some Fermi questions?
One questioning strategy worth trying in class is ‘Fermi questions’.
Fermi questions are named after the physicist and Nobel Prize winner Enrico Fermi.
He challenged his students to use estimation, common sense and numerical reasoning to work out quantities that were difficult or impossible to measure. He deliberately posed questions with limited information so that students had to ask more questions. His questions emphasise the process rather than the answer.
Examples of Fermi questions
