I once had a chemistry teacher who informed us very true and necessary things like:
- -- This is a test-tube
- -- This is a beaker...
- -- This is air
- -- This is nitrogen
(Much to everyone's surprise - but not our teacher's - they both looked the same!)
(and so on). [That's a bit of an exaggeration - but only slightly so].
I'm afraid none of us learned much chemistry.
The better way to enable learning would be to provide an instance of the 'thing' in question AND to demonstrate its properties/uses/use cases.
To me, the above seems obvious and utterly commonsensical. Above all, instead of going by RIGID rules, let the rules be made by the learner's needs, his/her curiosity.
What that chemistry teacher did was ALL WRONG! (As is what RH is suggesting).
("Still Shoveling Away!" - with apologies if due to Barry Garelick for any tedium caused; and a humble suggestion that all such tedium would be avoided by simply not looking at any message that is purported to be from GSC)
