I’m now done with the preface and chapters 1-2 of Accountability Frankenstein, and I just noticed the following mixed metaphor:
For a school official to say blithely that elementary teachers should deemphasize -ing word endings in language arts because -s and -es endings are on the test but -ing endings are not is letting the fear of test consequences drive common sense out the window (Tobin & Winchester, 2004)
Normally, you don’t drive in and out of windows. But on the other hand, maybe the idea of a car going through a window is precisely the image I want to convey.
