Three things you need to know about AI “detectors”

Instructors may not submit student material to AI Detectors: Terms and Conditions require ownership over the intellectual property that is submitted; Students own their IP, not instructors​.

  • Douglas College – Freedom of Information & Protection of Privacy act [FIPPA]
  • Terms and Conditions from Copyleaks AI detector
    • “By accessing and/or using the site or services for any purpose whatsoever, you agree to the collection and use of any information or documents uploaded to the site or services, in addition to the collection of your personal information, all in accordance with these terms and under our privacy policy. Unless you delete any uploaded documents from Copyleaks’ servers in accordance with our privacy policy, we reserve the right to keep such uploaded documents in a data-base and use such documents for all purposes listed in our privacy policy.”

Student work may not be submitted to AI detectors without their consent: Students have the right to know if their material is being submitted to a third-party (who may profit off their IP) and the right to withhold consent (Rosenfeld v. McGill, 2004)​.

  • At Douglas College, you are required to get consent from a student before submitting their work to any third-party site that has not been properly vetted.
  • Students must be able to opt out without penalty.

“Detectors” don’t work as advertised: Open AI recently admitted this by pulling its own “detector”; Beware of the “Appeal to Statistics” Fallacy

What do I need to do with this information?

If you manually calculate your marks and grades using something like Gradekeeper or Excel, make changes to the percentage ranges for each letter grade. If you use Blackboard, make sure you use the New Letter Grade Standard DC grading schema.

What happens to my assignments on Blackboard?

The new grading schema may be currently available as an option on Blackboard when you are creating or editing assignments or tests. If it is not, it should be available by week three. Keep in mind that assignments and tests that copied over from a previous course might carry over the old grading schema. Check over all of your assignments to make sure they are using the new grading schema before making them available to students.

What if I have any questions about this?
