David Wiley has a new post announcing that a study to compare students learning from traditional textbooks compared to open textbooks. From the post:
Because expensive, traditional textbooks have to be passed from student to student over 4-7 years, students are typically prohibited from marking in the books in any way. By contrast, because the open textbooks are so inexpensive as to be considered consumables (from a budget perspective), students will be able to engage these books through active study processes like highlighting and annotating.
