The professor behind an AI-generated textbook says that her error-ridden experiment was actually a resounding success. The AI textbook was made with Kudu, a platform for creating digital textbooks started by another UCLA professor. Stahuljak says she created the textbook by supplying her own notes to the AI tool, which was instructed not to pull from outside sources. After deploying the AI textbook, Stahuljak claimed that “engagement went up” compared to classes that didn’t use it. A considerable and still growing body of evidence shows how AI tools may diminish critical thinking skills and attention spans.
