The professor, David E. Pritchard, led a research team that analyzed student performance in an online homework system called MasteringPhysics.com during four different semesters. The researchers were able to measure the time spent on each question and look for suspicious work patterns. If a student took less than a minute each answering several complex questions and got them all right, for instance, the system flagged that as likely cheating. “Since one minute is insufficient time to read the problem and enter the several answers typically required, we infer that the quick-solver group is copying the answer from somewhere,” said the researchers in a paper due out today in the free online journal Physical Review Special Topics–Physics Education Research.

Based on later surveys of the same students, researchers found that the culprits typically copied answers from friends, by logging onto a friend’s account on the system to copy work or by getting answers via e-mail or instant message.

For veteran teachers this is hardly a surprising revelation. The complexity of cheating and plagiarism schemes has increased with the rise of technology and ability to transfer information digitally. Cellphones and other devices have made cheating easier than ever, see The Cheating Heart for an overview. Furthermore, despite the education aimed at informing students about copyright and intellectual property, it is clear that generation y and future generations seem to have a different perspective regarding copyright.

While many would point to this as indicating the need for better detection systems, real success comes from successfully encouraging students to choose not to cheat. Restrictive access to technology and more robust detection schemes may seem appealing but lead to students and teachers engaging in a never ending cycle of trying to outsmart one another. This doesn’t mean ignoring cheating or giving it a free pass. In this Web 2.0 world, it does mean, demonstrating a better way and allowing students to make choices. If unethical, according to Professor Pritchard, these choices mean that cheaters will earn the scores they deserve.

In my next article I will outline three keys to building an environment supportive of ethical decision-making. Until then I’d like to hear your comments and observations.
