I have to do an essay for my primary PGCE on one of the theories we've been learning about and how it relates to classroom practice. We have to propose the question to be discussed and I have a mental block about it. I'd like to do mine on Vygotsky and the ZPD but am struggling to think up a focus for the essay. I'm doing my teaching practice in KS2. I don't think I'll have trouble writing the darn thing once I get a title/angle in my head. Any ideas gratefully received!
