Turnitin, the leader in originality checking and online grading, today announced the results of a new study analyzing instructor feedback on 2,093,396 student papers submitted through GradeMark, the Turnitin online grading tool.

The study found that while instructors have accepted online grading as mainstream, they are finding the same types of grammatical and compositional errors across secondary and postsecondary grade levels.

A webcast, “From the Margins: Providing Effective Feedback on Student Papers,” to present the study results will be held on Thursday, October 11, 2012. To register, please click here. Additionally, educators may click here for a copy of the full study results. The study, conducted in Spring 2012, examined the frequency with which secondary and higher education instructors had dropped 30 million QuickMark comments on student written work within the Turnitin service.

Key findings of the study include:

● There is remarkable consistency in the types of comments used across secondary and
higher education.
● Although “missing comma” is the most frequent mark used, comments related to
composition comprise 13 of the top 25 marks.
● “Awkward” is the second most frequent comment used by instructors, prompting a
recommendation for more substantive guidance to students.
● The top 5 QuickMark comments used by instructors are: missing comma, awkward, spelling
error, delete and cite source.
● Online grading is going mainstream with favorable results.

“The fact that QuickMark comments are shared provided us with the opportunity to examine instructor grading behavior on a very large scale,” said Jason Chu, senior education manager for Turnitin. “This study highlights how instructors are deploying best practices in grading and sheds light on how online grading can be better leveraged to enhance student engagement with feedback on their written work.”
