The extensive adoption of AI has precipitated a crisis in academic integrity. While studies attempt to quantify cheating, less is known about the motivations instructors believe students have for using AI in prohibited ways.

- (1) Academic System Gaming
- (2) Digital-Academic Literacy Gap
- (3) Performance Anxiety
- (4) Normalization of Dishonesty
