The scores they attach to writing are based on mathematical equations that assign or deduct value according to the programmer's instructions. The software vastly accelerates the feedback loop."īut computers are illiterate. "Or there is no time to do anything about it. "If it takes a couple weeks to get back to the student they don't care about it anymore," he said. ![]() Where it might take a human reader five minutes to attach a holistic score to a piece of writing, the automated system can process thousands at a time, producing a score within a matter of seconds, Wilson said. Those who have participated in the traditional method of scoring standardized tests know that it takes a toll on the human assessor, too. "Writing is very time and labor and cost intensive to score at any type of scale," Wilson said. Classroom teachers can evaluate writing in less time, of course, but it still can take weeks, as any English teacher with five or six sections of classes can attest. Their scores are calibrated and analyzed for subjectivity and, in large-scale assessments, the process can take a month or more. When scored by humans, essays are evaluated by groups of readers that might include retired teachers, journalists and others trained to apply specific rubrics (expectations) as they analyze writing. If computer models provide acceptable evaluations and speedy feedback, they reduce the amount of needed training for human scorers and, of course, the time necessary to do the scoring.Ĭonsider the thousands of standardized tests now available – state writing tests, SAT and ACT tests for college admission, GREs for graduate school applicants, LSATs for law school hopefuls and MCATs for those applying to medical school. The benefits of automation are great, from an administrative point of view. Those who used standard feedback methods without automated scoring said they spent more time discussing spelling, punctuation, capitalization and grammar. In earlier research, Wilson and his collaborators showed that teachers using the automated system spent more time giving feedback on higher-level writing skills – ideas, organization, word choice. However, Wilson's research is the first to look at how the software might be used in conjunction with instruction and not as a standalone scoring/feedback machine. Researchers have established that computer models are highly predictive of how humans would have scored a given piece of writing, Wilson said, and efforts to increase that accuracy continue. Both PARCC and Smarter Balanced are computer-based tests that will use automated essay scoring in the coming years. Other standardized tests also include writing components, such as the assessments developed by the Partnership for Assessment of College and Careers (PARCC) and the Smarter Balanced Assessment, used for the first time in Delaware this year. That test uses trained readers for all scoring. The National Assessment of Educational Progress, also called the Nation's Report Card, first offered computer-based writing tests in 2011 for grades 8 and 12 with a plan to add grade 4 tests in 2017. Finding reliable, efficient ways to assess writing is of increasing interest nationally as standardized tests add writing components and move to computer-based formats. Writing is recognized as a critical skill in business, education and many other layers of social engagement. The idea is to give teachers useful diagnostic information on each writer and give them more time to address problems and assist students with things no machine can comprehend – content, reasoning and, especially, the young writer at work. The software uses algorithms to measure more than 500 text-level variables to yield scores and feedback regarding the following characteristics of writing quality: idea development, organization, style, word choice, sentence structure, and writing conventions such as spelling and grammar.

Wilson, assistant professor in UD's School of Education in the College of Education and Human Development, asked teachers at Mote and Heritage Elementary School, both in Delaware's Red Clay Consolidated School District, to use the software during the 2014-15 school year and give him their reaction.
