Joyce Valenza has posted a great guide to using You Tube. You can find it here. As she says in the post, there are lots of times when you want to show students or other staff a You Tube clip but you don’t need all of it and you don’t want to start at the very beginning. Learn how to cue it to start when you want it to start.
You can find helpful You Tube tips galore in the post. In fact it would take a bit of time to work through them all. You will find Copyright, Tips on Sharing, help with music for your videos and a whole heap more. But wait, there’s more! There are more links in the comments.
