Often in Math and Science there are words that are used somewhat loosely. Almost like slang, in one context or the other the word is widely used and accepted to have a certain definition.

Sometimes, these words can have a completely different meaning in another context, or subject. The concept of density is an example of one such word. Ask a physist what dansity is, and you will get a totally different response than that of a mathematician when asked the same question.

Language Issues need to be addressed in the development of the lesson, as we want our audience to come away with a better understanding of the material and not be hung up on a word or two.
