AI can write a lesson plan in thirty seconds. It has no idea who your third-period class is. The AI Doesn't Know Your Students is a field guide for the version of AI teachers are actually living with — not the one sold to schools in consultants' slide decks. It covers what AI does (and doesn't do), how to use it without handing over the parts of teaching that matter, and how to help your students engage with it thoughtfully. Twenty-four chapters build one case: teaching is a relational act, and no tool, however capable, can replace the teacher who knows the student. The second edition adds two new chapters, on what a snapshot of a student is worth and on why an AI personalizes from a label instead of a person. Written by a working AP teacher, not a think tank. Practical enough for a planning period, honest enough to help. 350-page PDF, second edition. Instant download, no account required.
