Leading a Training
The best trainings I have attended are the ones that were hands on. I am the type of learner where I need to actually "do" in order the retain the information presented. I think this true for many, especially when it comes to using technology.
The trainings I have disliked are the ones where the presenters just talked at you, only showed slides/pages, and presented information that was not available to all attendees. I think slides can be good to use as a visual agenda (and to keep pacing), but do not need to be read directly or solely presented. Attendees do not want to be talked at for the entire PD.
