Freire criticises what he calls banking education where pupils are treated as empty vessels to be filled up with facts: in the UK this is called teaching to the test. Despite claims to the contrary, since schools are judged by test results, that is the only teaching technique that is done. There are of course many different ways of teaching to the test but at heart, teaching to the test is what happens.
