Hi We wrongly accused a student team of cheating on an IF-AT (see attached) At first glance they seem to know where the stars were....partial scratches just barely revealing stars Turns out when we compared handness (i.e. Students that scratch from -- right, left and middle -- each has an anomalous pattern of ³coincidence²) There still are some anomalous scratches on the attached IF-AT.....but it took away our confidence to call it cheating Jim Jim Sibley Director Centre for Instructional Support Faculty of Applied Science University of British Columbia 2208-6250 Applied Science Lane Vancouver, BC Canada V6T 1Z4 Phone 604.822.9241 Fax 604.822.7006 Email: [log in to unmask] Web: http://cis.apsc.ubc.ca e-Portfolio: http://ipeer.apsc.ubc.ca/wiki/index.php/Jim_Sibley_Portfolio ________________________________________________ © Copyright 2009, Jim Sibley, All rights reserved The information contained in this e-mail message and any attachments (collectively "message") is intended only for the personal and confidential use of the recipient (or recipients) named above.
