Grammar is generally always taught the same way. Students learn about subjects and predicates. Students learn the form of nouns, verbs, adjectives, adverbs, conjunctions and prepositions. If you moved from one Grammar course to the next, the pattern would be the same.
Technical Theatre subjects are much more robust. Because of this, we encourage our instructors to embrace the method of instruction that makes the most sense for their subject matter. The end result is that one course might be taught quite differently from another. This fluid structure allows us to provide training that students will retain. Perhaps one teacher's format is more appealing to you -- we certainly welcome that feedback. Our goal is that the diversity of training methods and subject material will lead to overall enrichment for our students.
