Formative vs summative use

Computer-aided assessment is great for formative assessment.

Students can try randomised questions over and over until they're happy.

Summative assessment can pose problems:

  • How to prevent cheating?
  • Can you ask sufficiently challenging questions?

  • Formative use in a pre-entry course.
