Contract cheating process student creates bid request sellers bid to complete work… for a competitive price student selects a seller - funds placed in escrow bidder creates original work student submits original work
Why bother? • Because students are using RentACoder. • 12.3% of bid requests on RentACoder represent contract cheating. • (3 week exhaustive check of RentACoder submissions i.e. 99 out of 803 bid requests).
Extent of use • 236 contract cheaters identified over a 2 month period. • 19 (8.1%) made only a single bid request. • 122 (51.7%) made between 2 and 7 bid requests. • 6 (2.5%) made 51 or more bid requests.
Redesigning assessment • Assess students when they can be monitored: • in lab assessments • Ensure that students understand what they have produced. • vivas • in lab assessment • Produce unique watermarked assignment specifications for every student.
