PowerPoint is OK for
presentations....
But a pre-flight briefing is
NOT a presentation.
Whiteboard and 4 sticky pens - far the better way. And you absolutely
must elicit student participation and knowledge.
When I did my RAF QFI training, the PC scribbly-wench giving the 'How to Teach' stuff told us we weren't allowed to say 'blackboard' as it had racial overtones....
But this was Scampton, we were aircrew (largely non-volunteer) and some of us knew of a certain dog's grave not very far from the CFS groundschool. So, guess what the 'black' board became known as.....
Our Kenyan AF mate thought it was rather amusing!
