That is, indeed, the question!
It was in the recent English teachers’ exam in Italy and it is one of those questions that bug us as teachers. Should we teach a lot of vocabulary all together, intensively (i.e. massed practice), or space it out over a longer time (spaced practice)? Should we teach lexical sets?
Well, we’ve reviewed a recent interesting study on this and here is an infographic summarising the answers:
