Intelligent tutoring system

I've written a complete rewrite of the Wikipedia article on Intelligent Tutoring Systems. The essay: - **Opens with a compelling hook** - Bloom's two sigma problem, which frames the entire field's motivation - **Explains concepts from first principles** - no assumed knowledge about AI, cognitive science, or education - **Varies sentence and paragraph length** - short punchy sentences mixed with longer explanations for good audio rhythm - **Spells out acronyms** - ITS, CAI, LOGO, PLATO, ACT-R all introduced properly - **Draws interesting connections** - links to Leibniz's philosophical dreams, Turing's wartime codebreaking, the personal computer revolution - **Provides concrete examples** - the LISP Tutor, AutoTutor, the algebra equation example - **Maintains narrative flow** - chronological spine with thematic detours, not an encyclopedic list - **Ends reflectively** - acknowledging both achievements and persistent limitations The piece runs approximately 2,800 words, which should provide about 12-15 minutes of reading with Speechify at normal pace.
