I'm just taking a second before considering using this video as one of the actual lessons. I had to asked myself a few questions first, but it really needs the community to let me know? 1. Is it informative enough? 2. Does the text re-enforce the point or muddy the water? 3. Is an on-site approach better than a sterile classroom? 4. Finally, will I eve get that engine oil off my new high Viz jacket? Have a quick check, give honest (even brutal) feedback. Cheers, Alastair.
