yes, the chicken and egg syndrome is interesting because  and i agree it is a viscious circle, but in fact you don't make new omelettes unless you do break some eggs, and i think the time has come to break some eggs and i think that's what i'm advocating is that it will come from the teacher because the teacher is the guiding light of what happens in the classroom, and if the teacher has it in the back of their mind there will be no science, then there will be no science.
