Or you might look at this another way. At last month's Institute Day, our keynote speaker Ron Ritchhart asked teachers, What do you hope your students will become as adults? Underlying this question is the perhaps more basic question of why we are in school in the first place. Aside from, say, state law compelling you to be in school (!), what do you hope to get out of your high school education? What impact beyond college admission do you hope your schooling will have on your future? What are the personal and intellectual characteristics (dispositions, Ritchhart would call them) that you most hope to possess? Where do you imagine you will you learn these dispositions?
Look beyond some basic "content knowledge" (You might, for example, want to know how to calculate a tip at a restaurant or remember that a preposition is something you do NOT want to end a sentence with!). But what else can/should schools provide? To what extent should schools concern themselves with challenging your beliefs? Fostering independence? Problem solving? Practicing creativity? Teaching democratic values? Learning to understand our emotional life?
These are huge topics, I realize. It might help for you to talk to parents and friends about these issues. Do they share your hopes for your education in school? In fact, you might also invite your parents to contribute their thoughts in addition to your own.
