And I'm but sorry not thinking about exams smacks of naivety
Read my post again. I said both are important.
Open a book photograph page 127 close book now tell me what was on page 127
You really have a talent for misreading stuff. I'm suggesting that after having generated something on the board or co-operatively pupils photograph it rather than copy it down. Yes, taking a photo in itself has zero educational value. What it does is free up time for the stuff with value and ensure pupils have a record of the work. Whether they use that is up to them.
Are you seriously suggesting that copying notes from a board or a book is a valid method for anything other than the odd snippet? Copying notes is a time time filling / crowd control tactic with tiny educational value.
Handwriting and typing skills are massively important and neither are improved with a point and shoot photograph.
Can't argue with you there, but again you've got the wrong end of the stick. I'm not trying to improve those skills in this way. That would be silly. If I want pupils to improve those skills we do an activity focused on them.
I'm off oot on the bike now.
