Does anyone have thoughts to share (good or bad) on either or both of these resources? I will be teaching Gen Chem I and II at Rider University this year and we are adopting these teaching tools. The textbook is available free and therefore represents a significant cost savings for the students (https://openstaxcollege.org/textbooks/chemistry). I have looked through the book and it seems to be pretty solid, but haven't used it for teaching yet.

In our introductory class, we've periodically used Sapling online homework system.  We are looking at a new book for the fall that comes with the Smartwork homework system which seems quite a bit like Sapling.  Anyone have any experience with both and can talk about the differences and pros/cons other than price?   

I am planning to incorporate Sapling Learning online homework in my Foundations of Inorgnaic Chemistry class and my Advanced Inorganic CHemistry class. I've not used this program before, and am on the steep side of the learning curve. If you have an established course that I can adapt, that would be great. Also, I will be authoring questions as I need. Id love to crowd-source authoring of questions so that I'mnot just relying on my own perspective. Thanks!
