Detecting cheating: do two workbooks have the same origin?
Posted by Heath David on August 01, 2001 11:53 AM
I teach a course in Business Calculus at Virginia Tech for which students use Excel to complete assignments. A few times each semester, I run into a pair of way-too-similar labs that looks like one person copied another person's Excel file, made a few cosmetic changes, and resaved the file under his own name.
In the File Properties, the Creation date and time are usually identical for the two files. Are there other concrete, telltale signs I can look for to determine if two student submissions were once the same workbook?
Thanks in advance,
