Ahh, Scantron. They have been a mainstay of many teachers’ formative or summative assessments over the years, especially when multiple choice activities are concerned. I remember taking my cards to the grading machine in the teacher’s lounge (sometimes waiting several minutes for my turn!), and when I slid each student’s answer sheet in, I prayed for near silence (meaning few if any misses) and hoped to not hear the staccato click-clack revealing a student had a number of wrong answers.[:]
