A recent New York Times article highlighted software from EdX, a nonprofit enterprise founded by Harvard and the Massachusetts Institute of Technology. EdX software uses artificial intelligence to grade student essays and short written answers. The tool requires human teachers to first grade 100 essays, and the system then "trains itself" to assess the work accordingly. Supporters of the software say that EdX allows students to repeatedly improve their answers, without waiting days or weeks for grades. Skeptics say the automated system is no match for live teachers, and the technology can be easily fooled.
