"They"

As an undergrad, I hear the term "they" a lot. What "they" want "you" do to. The work that "they" want "you" to show when doing a Calc II "problem". I honestly think this is a very bad way to go about wording things when teaching to students of any age. When you, the instructor, use these pronouns, you make the education of your students revolve around "them". The people who write "the tests", the people who have written "the tests" and will be writing more tests. The point of teaching any form of calculus (passed the superfluous Calc I, from which I have seen questions such as "what is the graph of |y|=1?", at least at SUNY Binghamton) or any theoretical (or even practical) study is to build a foundation of thinking for higher practice. Calculus is the foundation for some higher math and most higher physics. If you are teaching a convention, it is not because of the rules; the rules are, hopefully, incidental of the convention's strength.

So forget about what "they" might want. When you're discussing standards or showing work, and a student asks how they "should" do something, style-wise or otherwise, say not "this is the way they want" but "this is the way that makes the most sense".

Unless it doesn't make sense. Then mention "them" by name and insult them appropriately.
