Scantron inventor dies

The Scantron grading machine, a type of optical mark recognition (OMR) system used for grading tests and quizzes, has been used by countless professors over the years to make grading more efficient.  Especially in large classes or in courses with many assessments.

I'd like to take a moment to salute the Scantron's inventor, Michael Sokolski, who passed away recently.

Although there are still a few righteous professors out there who never learned how to create an effective test using Scantron scoring--and thus loudly declare such tests to be worthless--most 21st-century professors know how valuable a tool the Scantron is to have in one's toolbox. 

Here is an interesting article about Sokolski's contribution . . . and the whole topic of this type of testing.   If you want to know "why a No. 2 pencil?"  or "can my pencil-sharpening technique affect my grade?"  then you HAVE to read this!
