I have taught English as a foreign language for many years: these are some of my thoughts/witterings on the subject.
The image of a match being struck is inspired by some graffiti written on the wall of a school I taught at:
Gli studenti non sono vasi da riempire ma fiaccole da accendere
Students are not vessels to be filled but torches to be lit
Which Google tells me is actually from Plutarch. Whoever said it, it’s a wonderful view of teaching.
