Texas College Bridge uses a personalized learning system, so cheating can be detected in the system-use pattern of the student. How? We record all student interactions with the system, including what topic material is studied and for how long, progress though frequent quizzing, and more. Basically, when a student uses the system, they create a characteristic pattern of use, like a fingerprint. If a student cheats by using test answers supplied by another person, there is a divergence from the normal use pattern that is visible to an instructor, allowing the instructor to intervene and take appropriate action.
