Candelle, The changes have only been introduced recently, so any effects won't show in the current workforce.
I agree with you about basic grammar, but this isn't 'basic' grammar. Much of terminology seems to have been take from the language of teaching English as a Second Language. For example, like others on here, I had never seen the word 'determiner' until I looked it up a few months ago. As far as I'm concerned 'the' is the definite article and 'a(n)' is the indefinite article, but nobody needs to know that, unless they're learning a foreign language, when the terminology becomes a useful shortcut.
Another example is 'conjunction'. Until recently, primary school pupils were taught that these words are 'connectives'. I don't know why the terminology changed, but the point is that most people can use 'and', 'but', 'when', 'because' etc correctly without knowing the grammatical terminology. I most certainly did not learn about subordinate clauses when I was at primary school. I bet the majority of people still don't know what a subordinate clause is.
The fact that posters on here write accurately, but are still achieving low scores, should say something.
I would like to know who was in the team which came up with this nonsense.
