In more current terms, Bloom’s taxonomy shows Knowledge to be the largest of the six stages of organized progress, regardless of whether it is drawn base up or base down like this. In language-acquisition, where knowledge tends to mean vocabulary, you will hear arguments on whether this taxonomy is valid, but it is more true than not, especially to those of us who tend not to use words and phrases we are not sure of. Remember, knowledge means different things to different people . . . which is the main reason for this E:P:N-based discussion. Right?
