Frequently Asked Questions

Is it okay for teachers to use AI for lesson planning?

Yes. AI is a planning tool, not a teaching replacement. Using AI for lesson planning is similar to using a textbook’s teacher guide — it provides a starting framework that you customize for your students.

Which AI tool should teachers start with?

MagicSchool AI — it’s free, purpose-built for education, and requires no prompting expertise. Start there, then add ChatGPT or Claude for more custom needs.

Can AI grade essays accurately?

AI can provide preliminary feedback on writing structure, grammar, and adherence to rubric criteria. Final grading decisions should remain with the teacher, especially for subjective assessments of argument quality and creativity.

How can teachers use AI without compromising student privacy?

Never input student names, IDs, or personal information into general AI tools. Use anonymized data or fictional names. For student-facing AI tools, ensure FERPA compliance and get appropriate permissions.
