Choosing AI Tools for Your Learning Goals

How to Use AI Responsibly in High School

Sometimes the line between appropriate use and plagiarism or cheating can get blurry- especially with AI helping you along the way. To stay out of trouble we recommend you follow these simple guidelines: 

• Use AI to expand or explain not to create an answer from scratch. It can walk you through concepts, but you should create and finish the work. 
• Check your school’s AI policy or ask your teacher for the school rules around AI.
• AI can make things up. These are called hallucinations, so make sure you double check all sources and facts that come from open LLMs. 
• If you didn’t write it, don’t submit it. Its a good idea to use an accurate detector to make sure the work you are handing in is yours. 
• Treat AI as your study partner- you still have to get the information into your brain and no AI tool can replace that. 

How AI Supports Learning in High School

AI can support your learning in many different ways aside from studying. If you integrate this tool into your workflow as a student you can get support all across your tasks and learning phases. Here are a few examples: 

Language learning 

AI conversation partners can help you practice speaking and writing a language without the hassle of arranging and paying for tutoring. 

Writing across subjects 

AI can generate outlines, brainstorm angles, and suggest revisions. Remember to use it to expand or carify your thinking, not replace it altogether. 

Math and science problem-solving 

Tools like Photomath and Wolfram Alpha walk you through worked examples the way a good teacher would, so you can fully understand a concept and solve future problems. 

Personalized study plans 

AI can take a syllabus and an exam date and turn it into a realistic day-by-day study plan. Just be cautious as it tends to be over-optimistinc and can create an unsustainable plan. 

FAQs

How do you choose the right AI tool for different academic tasks?

The best place to begin is your specific task. Analyze what you need to accomplish and then evaluate the tools based on how easy/ hard they make it for you to do that. Flashcards and memorization work best in tools built for spaced repetition (RemNote, Anki, Quizlet). Concept explanation works best in general-purpose AI (ChatGPT, Claude, Khanmigo). Math problems need dedicated tools (Photomath, Wolfram Alpha). Writing tasks benefit from grammar assistants (Grammarly). Most students use two or three tools together.

Are AI study tools free for students?

Most AI tools have a free tier or are free for students. If you want access to full features that’s going to cost you anywhere from $5 to $20. 

Is it okay to use ChatGPT for homework?

It all depends on how you use it and the assignment. Using ChatGPT to explain concepts, get practice questions, explore different angels, or do research is fine and can be helpful. Using the tool to generate answers or replace your own thinking is probably not going to serve you in the long run and may even violate some school policies. 

Which AI tool is best for high school students overall?

Most high school students have a few tools that they rotate through precisely because no one tool does it all. ChatGPT and Claude are strong for concept explanation. Khan Academy is strong for curriculum-aligned learning.
