Dancing about Trigonometry?

'Multiple intelligence' spreading in colleges

from the article:

Basically, multiple intelligence learning encourages students to learn a subject in a way that is most comfortable for them. It categorizes learning in eight groups of intelligence.

For example, a student who best learns through bodily expression may decide to perform a dance routine to demonstrate knowledge of a trigonometry theorem instead of taking a test.

The approach allows students who don't test well but who still understand the subject to demonstrate their knowledge in a different way.

While I feel it is important for educators to recognize multiple intelligences, I am a bit skeptical of the way this is described in this article. Part of learning any subject matter is learning its vocabulary, and the language of trigonometry is mathematical expressions and not dance. While, to be sure, one might find elements of, and analogies to math in the arts, that is not the same as learning math.

What are your thoughts on this?
