Ohio State: 83 students used group messaging app to cheat

Ohio State University has accused 83 undergraduate students of cheating on classwork using a group messaging app.

The school says the students violated the code of conduct for "unauthorised collaboration on graded assignments."

A university spokesman says the use of group messaging apps is permitted, but is subject to the same rules as any other communication.

The university's Committee on Academic Misconduct investigated after a professor in the business school reported the allegations in April.

Potential penalties range from warnings to expulsion.
