I can tell you as a middle school teacher myself, I discussed or
introduced dilation by negative scale factors however, it was not the item I tested.
But it is possible for a student to remember a dilation of scale factor
negative one. In class, I asked the students which scale factor would not
change the size in the hopes of reminding them of the multiplicative identity.
I believe the discussion is worthwhile as it hopefully prevents other
errors in the future.
