Sure. Thank you very much, Mr. Cash.
Courses for colleges are built from program standards that are established, learning outcomes, and those are passed on to individual courses. So you have a program. Courses are made up of different learning outcomes at the course level. Teachers will select material, either material that he or she intends to use solely in the classroom or that he or she may want the students to have by way of purchasing those materials, whether they are published materials, e-books, or anything of that nature. How they construct their lesson plans will be based on an attempt to achieve those learning outcomes. This will include, possibly, live, in-class lessons, skill-based work, reading material, and a whole host of methods in order to impart or facilitate the transfer of knowledge. Then they assess and evaluate that those outcomes have been met.
So they rely on either textbooks or material they create themselves. That material is purchased by the college and by the students as well. The learning takes place with that material. It's supplemented by anything that can be found within the public domain, for instance, that can be appropriate for that class.
I'm not sure beyond that.
