Academic Integrity: Using AI Study Tools Ethically
With increasing concerns about academic integrity, many institutions now use AI detection tools like GPTZero and Winston AI. Here's how to use AI tools ethically:
Use AI as a learning aid, not a replacement for understanding
Always review and modify AI-generated content to ensure it reflects your knowledge
Cite AI assistance when required by your institution's policies
Focus on using AI for process improvement (organization, research, drafting) rather than final product generation
Remember that the goal of education is learning, not just completing assignments. The most effective use of AI tools enhances your understanding rather than circumventing it.
