The author of this article on the Revised Bloom’s Taxonomy identifies Bloom’s original Taxonomy as organized by gerunds. Unfortunately, there are no gerunds in sight in Bloom’s original Taxonomy. Those are most certainly nouns that are derived from verbs, but that is not at all what a gerund is. A gerund, of course, is a verb used as a noun (similar to how a participle is a verb used as an adjective), whose ending in English is -ing (which, unfortunately, is also a participial ending, which leads to all sorts of confusion): Running is fun (i.e. the act of running is fun).
Interestingly enough, of course, the verbs that are identified in the revised Bloom are in fact gerunds themselves, as well as being verbs (gerunds being verbal nouns). The author is not incorrect to identify the revised taxonomy as populated by verbs, but these -ing words are the gerunds of the two (again, verbs used as nouns). The author too is not incorrect to say that the shift from the original to the revised is one of noun to verb; the words of the original are indeed nouns, but they are not gerunds.
