But this is a very different discussion (for example, see this link).
For example, this is the list of the most important terms and categories that every physic teacher has to know in order to teach the first semester of Elementary Physics (borrowed from the syllabus of a full physics course, where everyone can actually read it :) ).
But also a science teacher has to show students why the invention and the use of that language is important (without this linguistic practice there is no science).
Second of the very common reasons for students to fall behind is that a teacher does not unveil the logic for making decisions about various aspects of the subject; it's just "do as I say", without "why".
