OpenLearn (UK), OER, OCW
Over the last couple of years K-12 and Higher Ed institutions have been working together to create a pool of open courses available to anyone in the world. The learning “plans” are there, but it’s not always easy to gain access to the textbooks referred to in the syllabi. Still, teachers can use these lesson plans for added inspiration or as “Additional materials” that they point their students to. I found some excellent lists of topics for class discussion, for example.
