Machine Scoring Fails the Test
New Position Statement on Machine Scoring from NCTE, April 2013
[A] computer could not measure accuracy, reasoning, adequacy of evidence, good sense, ethical stance, convincing argument, meaningful organization, clarity, and veracity in your essay. If this is true I don't believe a computer would be able to measure my full capabilities and grade me fairly. -- Akash, student
[H]ow can the feedback a computer gives match the carefully considered comments a teacher leaves in the margins or at the end of your paper? -- Pinar, student
