This document discusses the 1X1 digital learning project in Catalan schools and addresses teacher concerns. It explains that the education department requires schools to use electronic textbooks and web-based materials that cover the entire curriculum using digital media like videos and simulations. These electronic books are organized into modules equivalent to textbook chapters and include recommended learning paths and references to supplemental online resources. Schools have freedom to choose electronic textbooks and the department subsidizes licenses for their use at 30 euros per student across all subjects. An example webbook from Richmond is provided that contains full unit contents, extra resources for students and teachers, and interactive activities with a design similar to popular websites to familiarize students and teachers with the format.
