So surprising, eh?
Sending children home from school to allow teachers to train is a waste of time, a leading academic says.
Pupils in England lose about a week of schooling every year as staff take "inset" days to brush up on the latest teaching techniques and Government reforms.
But research claims there is "depressingly little evidence" that it has any effect on teaching standards.
So teaching teachers the latest trendy educational nonsense doesn\’t improve teaching. Fancy that!
