In the introduction to LECTURE DEMONSTRATIONS & ASSOCIATED RESOURCES I was interested to read that, "Students need to learn the precision with which the words of the discipline are used to be able to communicate effectively." At a surface level this seems rather pedantic. Why such a strong focus on "words" at the expense of Physics content?
Then I thought back to my Physics education and realised that language is essential. To hold a critical conversation with someone else you actually need to understand the physics quite deeply. If the conversation is with another student who follows a similar critical process you both learn greatly from the exchange (I recall the philosophers call this the dialectic). Indeed I recall a neurological principle that states that logical reasoning is contingent on having some language to "reason with", although after a short search I have been unable to find a solid reference to this principle.
Experience suggests that many students try to bypass the effort associated with learning the terminology of their discpline in aid of a more intuitive understanding. I have no axe to grind when in comes to intuition, but perhaps we need to "hold the line" by forcing them to discuss their experiments in an erudite fashion?
