How Students Should Use AI Tools Ethically

AI tools are powerful learning accelerators when used ethically. The key distinction is between using AI to learn versus using AI to replace learning.

• Ethical use: Using AI to explain concepts you do not understand, to get feedback on drafts you wrote, to find research sources, and to check your solutions
• Academic integrity risk: Submitting AI-generated text as your own writing without disclosure, having AI complete assignments meant to assess your own knowledge
• Best practice: Check your institution’s academic integrity policy on AI use; many universities now permit disclosed AI assistance while prohibiting undisclosed AI submission
