"use of out-of-copyright reading material" rather than the best material. "homework and exams that can be marked by a computer rather than by hand" implying that we should only test (and thus only teach) skills that can be tested by computer rather than the skills that we want students to learn. Basically you'd be wiping out essay type questions (which test depth on knowledge) in favour of multiple-choice (which test breadth).
