My goal is to roll it all up into one video, rather than the feature length ordeal it is now.
Based on several people's comments I'm beginning to think you could watch them in any order and it wouldnt' be until the third that you got to that "Aha!" moment.
I think that's because we learn best through context.
What I mean is: if someone were to say they were angry because someone else laughed in their presence - you would have to find out the context - was that person making fun of them or not ? before you could understand if the laughter was misplaced or if the listener misunderstood their meaning for the laughter.
Context is everything, and when it comes to learning a technical skill like this, the brain has to learn the meaning of symbols used on the layout before they can learn their appropriate usage.
Since symbolic understanding is context independent (usually) the left and right hemispheres of the brain may never really "get" the full connection and how to use a thing until they can see a practical usage for it, through example.
In your two videos and the one diagram you address the issue of filtered selections and copy/paste methods from three different angles..
1) The first video is very left brain-ish, in that it demonstrates the rules and quirks mostly.
2) The diagram suggests a practical approach to usage - but in the abstract only - think of it as a lubricant preparing the way for "understanding".
3) And then the second video gives the knowledge meaning and a real world context - giving rise to the "Ahh Haa".
I don't think it is possible to teach this information in one sitting to tell the truth - because at first you introduce a foreign idea; and this creates a need, a vacuum for context - it's that lack of meaning that sets up the student for the next stage; the "getting it (at last)" stage. So, you need to create the need before you can fill it.
I have struggled with this paradox (as an instructor) for a lifetime, and have come to the conclusion that simply informing someone that they will need "this" or "that" information, and then proceeding to give them the info, before establishing the context - in a visceral way (for them) - always results in poor retention. And to make it visceral, it has to satisfy a need; a need which fills a vacuum.
I think this three tiered approach, though messy-er than a single (movie : consolidated) teaching method is actually a better and more natural way to learn for most of us.
Those are my twenty cents on it anyway.
