Question

Where would I find research supporting the no zero grading etc? I have been perusing your
material and am finding no documentation or bibliographies pointing me to research.

says:

I am not sure there is research on this. It is just a mathematical fact that it is wrong to use
scales with unequal differences - a zero in a grading scale where 60-69 is a 1 or D is a -6! if
you want further reading look for - Guskey - 0 alternatives, Reeves - The Case against and
the zero and Wormeli - Fair Isn't Equal. The first two are journal articles, the third is a book.
