Can markers detect contract cheating? Results from a pilot study     

Phillip Dawson  Wendy Sutherland-Smith 《Assessment & Evaluation in Higher Education》2018,43(2):286-293

Contract cheating is the purchasing of custom-made university assignments with the intention of submitting them. Websites providing contract cheating services often claim this form of cheating is undetectable, and no published research has examined this claim. This paper documents a pilot study where markers were paid to mark a mixture of real student work and contract cheating assignments, to establish their accuracy at detecting contract cheating. Seven experienced markers individually blind marked the same bundle of 20 second-year psychology assignments, which included 6 that were purchased from contract cheating websites. Sensitivity analyses showed markers detected contract cheating 62% of the time. Specificity analyses showed markers correctly identified real student work 96% of the time. Our results contrast with contract cheating sites’ claims that contract cheating is undetectable. However, they should be taken with caution as they are from one course unit in one discipline.  相似文献   

Effects of whey protein in carbohydrate-electrolyte drinks on post-exercise rehydration

The purpose of this study was to examine the effects of different amounts of whey protein in carbohydrate–electrolyte (CE) drinks on post-exercise rehydration. Ten males completed 5 trials in a randomised cross-over design. A 4-h recovery was applied after a 60-min run at 65% VO_2peak in each trial. During recovery, the participants ingested a high-carbohydrate CE drink (CE-H), a low-carbohydrate CE drink (CE-L), a high-whey-protein (33?g·L^?1) CE drink (CW-H), a medium-whey-protein (22?g·L^?1) CE drink (CW-M) or a low-whey-protein (15?g·L^?1) CE drink (CW-L) in a volume equivalent to 150% of their body mass (BM) loss. The drinks were provided in six equal boluses and consumed by the participants within 150?min in each trial. After exercise, a BM loss of 2.15%?±?0.05% was achieved. Urine production was less in the CW-M and CW-H trials during recovery, which induced a greater fluid retention in the CW-M (51.0%?±?5.7%) and CW-H (55.4%?±?3.8%) trials than in any other trial (p?p?p?p??1 in the current study.  相似文献
