May I ask why, and what you mean by 'ability to conjugate' (implicit or explicit?), and in particuaklr if you mean 'rote learning verb tables'
I think I would tend to agree with you that explicit conjugation is useful. A typical KS3 class will have some learners who 'get' the rules form examples, some who don't, and a significnat proportion who get the rules once explained, and need that explicit help. And, as I've said, I've yet to see a resource that doesn't respond to that model, for all the stress on communication. I'm still not convinced that starting with it is helpful-the metalanguage is off-putting, and it may not necessarily aid usage (and surely the aim is to get people using language correctly, not just knowing how it should be used?)
Why do you feel this model ceases at KS2? I imagine quite a lot of other teaching you might do is about eliciting rules from examples. I can understand why you wouldn't want to start with rote learnign the forms, but why not introduce them explicitly?
Hostility to 'rote learning' must annoy you. Seems bizarre to me that the pupils in the exercise I described would not be described as rote learning (when they were), but would be if given a verb table.
I am genuinely interested, and really sorry. I'll be returning to primary tecahing next year, and MFL provision is a key change I'm trying to get my head round. If I've seemed hostile it's because I've assigned you to a group claiming 'just get them reciting tables' which i've found most unhelpful, and repsonded to them not you. Sorry again.
