Students with executive functioning issues are naturally self-indulgent, with a strong preference for anything pleasurable and avoidance of anything difficult or unpleasant. They typically need instant gratification in order to maintain effort and engagement. Punishment and consequences after the fact really have little impact. Similarly, long-term rewards (such as grades or any reward associated with a good report card) are not immediate enough to keep them engaged. Continue with your attempts to provide external structure (lists, schedules, breaking large tasks into small units, etc.) but add frequent short-term rewards and other forms of positive reinforcement to keep her engaged. It is also important for the rewards to be linked to effort rather than outcome. Although it is natural for you to become highly frustrated and even angry with her, it is very important to keep things positive rather than getting into a power struggle (which she will win). Executive functioning issues are very often associated with ADHD, and finding the right ADHD medication can significantly improve the situation. Good luck!
