Cheating in Computer Science

2010/12/03

Many computer science teachers are very concerned about students cheating in their courses. Surveys report that almost three-quarters of high school students admit to cheating within the past year.

Many people say that the Internet has made cheating easier and harder to detect and they wonder if the moral fabric of our youth is fraying.

He wonders whether the game itself encourages cheating, and suggests that teachers could restructure the game so that cheating is less rewarding and less likely.
