It might be useful if you would clarify the above.
II: As I understand modus ponens, it consists of the logical train: 'A' implies 'B'; 'A' is true; Thus 'B' is true.
III: To my mind, the above logical train appears to be almost essentially a part of living in the real world. I would claim that it appears entirely unlikely that a child could grow to school age (and then beyond) without developing through his/her life experiences a 'sense of modus ponens'. It's not quite as fundamental as, say, breathing - but we all do develop it to some extent or other. To be sure, most students are not adequately trained in logical thinking so that they properly develop such senses and abilities for their own and society's benefit.
(In a recent posting, Clyde Greeno had suggested what I believe would be the right approach of helping to inculcate and develop this sense)
I observe, from your arguments above (and below), that some students are not adequately trained in clearly expressing whatever it might be that they want to state. > > > In fact, this is just what is done in ALL of > 'teaching', of whatever subject.

So I fail to understand the context of your above statement.
ii) Even if I did understand the context, I must confess that I don't at all understand what you mean by the above.

There is no ignition. > I would agree entirely with the part of your argument in the above claiming that humans are very differently gifted, I must confess that I have not been able "to get" most of whatever else it is that you may be wishing to convey in the above. This may be attributable to a deficiency in the way I think (as a "not-get") or a deficiency in the way you express yourself.
Based on whatever I HAVE been able "to get" (possibly incorrectly), I'd suggest that - if you are correct - it may well now be time to rescind a good number of the 'societal advances' we humans believe we have made over the past several centuries and reform our societal systems into "the gets" and the "don't gets".
That becomes far too complicated for me to follow as, by and large, I have gotten myself accustomed broadly to the idea of 'democracy', i.e., "government OF the people, BY the people and FOR the people" - the aim being to enable 'equitable treatment' of all. Of course, we have little accomplished that aim in any society in our world, but that is quite another matter.
I recall that you had in another post expressed the possibility that some of us - in comparison to 'ordinary human beings', I presume - may be 'mutants' of sorts (in regard to our abilities of 'getting' and 'not-getting' certain subtleties of thinking). To which I had responded, "X-MEN FOREVER!" (words to that effect). If you are correct in your premise and arguments, this may well be an idea worth exploring for yourself and others who think like you. I must confess that I'm not much 'in tune' with this line of thinking: frankly, it truly repels me. > > Also, as I have noted before, I work in a demanding > field that relies heavily on those elements I > expressed earlier.

However, I HAVE seen schools (and other parts of the societal systems in which we function) setting up huge barriers and discouragements that tend to hinder or even prevent children learning effectively. > > > I am not able to view videos easily, so haven't > looked at Clyde Greeno's videos.

If you will kindly look a bit more carefully at what had been claimed in the above, you may (or may not) observe that the argument presented was that we do not know "HOW" a child learns.
Trust me, RH, you do NOT know "how" a child learns. (If you believe you do, perhaps a major paper or book would be in order).
And perhaps you might like to apply some 'intuition, instinct and habits of mind' to the minor issue of at least arguing specifically on issues raised and not on those not raised. > > Now, the answer to your riddle, by means of an > analogy that you might understand... > > You have heard the line "If a tree falls in the > forest and no one is there to hear it, does it make a > sound?"

I have long enjoyed the saying - and still do find it very well worth contemplating (and exploring).
Thank you for enlightening me that it is "a play on the semantics of sound and the sense of sound". (I had always believed it was an expression of something rather deeper, but thank you anyway).
But I'm afraid I don't 'get' your analogy at all, alas. I ask the question:
"When an analogy is drawn, and no one 'gets it', does the analogy actually exist?"
I'm not here claiming that NO ONE 'gets' your analogy - just that I don't.
Sorry about that: I guess you should just put me into the category of "not-gets" in your brave new world.
