If the teacher thinks the economy has greatly improved, she’s beyond help.
If the teacher cannot understand last week as history, the numbers of the last few years do not indicate that the economy has, in fact, not improved, the teacher seems incapable of grasping the events of world history, period.
I must ask, as much as I hate to, is the teacher a member of an official 'minority', because should that be the case, any concerns expressed about the teacher will likely be branded with a work ending in -ist.
Utmost care must be taken to parse any complaint in such a fashion that any allegations of _____-ist bias on the part of student or parent will be deflected.
Otherwise, do what I did in public school (yes, even then)--give 'em what they want to hear for the grade, and know the truth. (Game them.)
