4 mei 2012 | Machines conquer student grading as complex thinking becomes assessable through mathematical algorithms. Studies claim this to be even superior to any human grading. Harvard’s teaching experts reflect on this and ask: “What are we testing for, again?”
In the past, algorithms have been the domain of mathematicians.But step by step they conquer other areas ranging from matchingcouples on dating websites to allowing teachers to gradepapers automatically beyond grammar checks. Recent studies nowclaim that software programs like E-Rater are even more efficientand more accurate than a human grader could ever be.
