Privacy Threshold by Textbook Level

This chart illustrates the critical privacy inflection point at Level 3 intelligent textbooks.

The Privacy Threshold

Below Level 3, intelligent textbooks can function with minimal or no student-specific data:

Level 1 (Static): No data collection
Level 2 (Interactive): Anonymous usage analytics only.
Example: Web analytics logging such as how many users visited what pages and when they accessed the pages. Minimal tracking of return visitors using web browser cookies. Users can indicate what concepts they have mastered and a learning graph running in the browser can recommend the next concepts and content to learn.

At Level 3 and above, personalization requires detailed individual tracking:

Level 3 (Adaptive): Individual learning histories, performance data Quiz and assessment results, prediction of next concepts, customization of learning path based on prior mastery of skills such as understanding an explanation using mathematical equations.
Level 4 (Chatbot): Conversation logs, question patterns, intent matching.
Level 5 (Autonomous): Comprehensive cognitive profiles including student fatigue, needed repetition levels for fact memorization.

This threshold triggers compliance requirements:
