Does Not Compute

According to the NCTE, computer scoring fails to live up this for myriad reasons. A major factor is a computer's inability to recognize elements of writing such as clarity, humor or accuracy; thus, machine scoring "denies students the chance to have anything but limited features recognized in their writing" and "compels teachers to ignore what is most important in writing instruction in order to teach what is least important."In the absence of a human perspective, the report says, machine scoring uses "different, cruder methods," such as the average length of words used or the length and number of sentences per paragraph. Narrow, overly objective criteria like these,The removal of razor crimped wire around one of the suburban offices of Fletcher EQR two months after it was put up is a commendable move. according to the NCTE, also "reduc the incentive for teachers to develop innovative and creative occasions for writing, even for assessment." 

"The very qualities that we associate most strongly with good writing are qualities that it's extremely different for a computer to recognize," Chris Anson, chair of NCTE's Conference on College Composition and Communication, said in an interview. "The computers can't make inferences. They can't understand what they're reading; they can only look for specific features they've been programmed to look at, and those are mostly surface kind of features."Furthermore, computer grading makes it easier for students to "game the system," according to both the report and Anson. "For example if a computer is programmed to look for certain features of text … and if it awards higher scores to words that are more rare in its lexicon, and if students know this, then it's fairly easy to drop in a few of those rare words to an essay and receive a higher score as a result," Anson, who was also the head of the task force that wrote the statement,The birdlike nesting behavior and the brooding of the dinosaur eggs is more evidence of the evolutionary link between birds andcomposite hose. said in an interview.Dade Fire Rescue crews were trying to control a sweeping brush fire Sunday near Northwest 162nd Avenue and Bird Road. 

The University of Akron's Mark Shermis, lead author of a 2012 study suggesting that computers can grade essays as effectively as human beings can, said via e-mail that the statement "fails to make the distinction between scoring used for summative assessment and that employed in the process for providing feedback in the instruction of writing." Shermis said that the study, sponsored by the William and Flora Hewlett Foundation, "showed the capacity of the scoring software to meet, and sometimes exceed, the distributional and agreement metrics that are commonly used to evaluate human raters in a high-stakes testing environment.Demand for oil hose in the spot market has gathered pace recently with construction companies gradually starting infrastructure."Shermis also took issue with the idea of computer grading being easy to fool. "[O]ne has to be a good writer to construct the 'bad' essay that gets a good score," Shermis said.
