This idea has been developed and deployed to Canvas

There are certain instances where student answers to fill in the blank questions should be capitalized to be considered correct.  Proper names in History and English courses for example, or element symbols in chemistry.  It is understandable that the default for student answers to be considered correct is not case sensitive, but teachers should have the option on a quiz or quiz question to turn on a case sensitive function if desired.
