The research is conclusive that most students understand and remember more when they read paper-based textbooks over electronic versions. There is less of a dichotomy with fiction. While researchers are trying to better understand why this is the case, the current understanding is that the scrolling layout of textbooks does not lend itself to deep reading and reflection. The exception would be for students with specific learning disabilities where the benefits of technology in features such as voice over and option to adjust font size and contrast outweigh the concerns.
