Is the objective of the GCSE EPQs to learn how to independently research and write up a long report? EPQs are like a mini-thesis, right??
I don't know what objective is, but it is relevant topic to DD's likely Uni course. DD couldn't think of another GCSE she wanted to do, though, so it was lifesaver for her ,and now it's submitted, she can use most of that scheduled time for revision & social sessions (fine by me). She has loved the adult atmosphere, they bring own tea/coffee & snacks to share during the sessions. Yes result is like a minithesis, DD's is 42 pages (+references) about whether Xdrug should be legalised for medicinal purposes. She has to do a 5 minute presentation which she thinks is absurdly too little time; I said just show a title slide & results/conclusions.
There is no word limit, which I disapprove of. They should be encouraged to be concise, too. There are very real word limits in university essays.
One of the others did his EPQ in a physics question (whether X-method or Y-method resulted in better proof for Z-theory). I wonder if they'll find a marker for that one!
