Why do all German language resources suggest learning nouns with "der, die and das"? Assuming the noun is singular, a noun heard in context with either "die" and "das" can have its gender uniquely inferred. But "der" could be male or female. So why not learn "den, die and das"?

Der can be f or m but not in the same case. And knowing what the case is is uniquely applicable to the article so the two can’t be separated. Eg, in Dativ der is always f. But what if you don’t know it’s Dativ? Well, then it doesn’t really matter which article you use.

I just feel that when you start learning German you learn these associations: der = masc., die = fem., das = neut. and then you see "der Schule" for the first time, so you'd assume it's masculine. If you learned "den = masculine" instead then you might be confused but not wrong.

Technically you should just learn word gender, but easiest is pairing with the definite. And then the problem is being in non-nominative case, which _may_ confuse... but in the end there should be no confusion: Der Schüle is just in another case, because Schüle is a f. word

That's understood, but why make it harder for the student by choosing a case without a one-to-one mapping between articles and genders?

My German is a bit oldie (haven't spoken or written almost any in 11 years) but gender != plural, the mapping is 1-1: a word is eithre masculine, feminine or neutral (and each can be plural as well)

No, that's absolutely correct, but there are six possible cases (der, die, das, den, dem, des) which are distributed across the different combinations of case, gender and singular/plural. But if we ignore plural, then "die" is *uniquely* feminine, "das" is *uniquely* neuter...
