> R Hansen says: >>Forget a sixth grader, how exactly do you teach modus ponens to anyone? >>Again, to my analogy, how do you teach someone what a rose smells like? # You take them to a rose bush, and let them smell it, and say, "This is how roses smell". If you are unwilling to call that "teaching", you have have confused "teaching" with "telling" ... as have all too many American educators.
# Likewise, you take them to where they can experience modus ponens, and say "This is called 'modus ponens'." And the easiest and most meaningful place for learners to encounter modus ponens is within their own routine conversation. All functional humans naturally use it ... its built into the evolution of their thinking processes. Any "teaching" of it is merely calling attention to it, and giving it a name ... which does, indeed, pave the way for further learning more about it.
