Popper is no doubt a great philosopher and had enough understanding of the sciences to say substantive things about the context of justification and proof of scientific theories. Unfortunately, in Portugal he began to be a fad used and misused in very different contexts. This was not Popper's fault but when you stay at the level of words like controversy,refutation, without knowing where they come from, science teachers to be carried away and entail chaotic views in their teaching. I am all for the presence of epistemology in the training of science teachers but let's do it in a proper way.
