Prompted at the right moment - you can having suprising effects.
I caught this on BBC Radio 4 at 08:45 this morning on the way to the dentist. Yonks ago I started a blog 'nudge learning.' It's not a new idea at all. In advertising, for decades they have taught creatives that all you are doing is influencing a shopper as they reach for a product to buy theirs not the other one. In corporate training they have 'just in time learning' where you 'position' the learning alongside the job: you learn as and when you need to.
