Even Open Educational Resources are a form of bundling. As anyone who has worked with OER knows, selection and curation are major components of doing it well. It’s a big internet; knowing what to select and how to put it together is where faculty come in. While OER can offer significant and welcome cost savings for students, they can also customize course materials to be exactly the way faculty want them. This is the polar opposite of autodidactism; it’s taking the faculty-as-guide model into the very guts of the books themselves.
