I worry that I sometimes waste my students’ time. I know the standard lower levels of our math curriculum have antiquated parts. I need to devise ways of delivering this required material in a modern context.
I worry that my students will embarrass themselves after they graduate and apply for their first job. I worry that they will misspell or mispronounce a word or write incomplete sentences or reason sloppily or be ignorant of a common math concept. Grammar counts when I grade written work.
I worry that I sometimes treat students like they are stupid. They are not stupid. They are just new to the material. I mean to treat them like adults using adult vocabulary and adult reasoning and adult expectations.
In sum, curriculum, standards, respect – of course.
