The last few paragraphs - Lecture-based, Student-based
That text is only meant to introduce the distinction between Lecture-based and Student-based. There are two sections in Use OER that cover both in a little more detail. If you intend to make a Student-based OER, then it may affect the development model you choose.
However, I understand if it is "cart before the horse" and will delete if you feel they are out of place.
