Managing the textbook publishers

[stemer]

Yeah, I steer clear of anything online, and allow students to buy any edition of the textbook.  Just what textbook publishers hate.  Oh well.

Yes but it is a complete nightmare managing all the possible editions especially if you are assigning questions/problems from the textbook or partial chapters as reading assignments...:(

I use them in math and I use the online homework. I teach primarily lower-level and developmental math, and I think that the gain from having homework that is automatically marked (for computational things) outweighs the cost of the software. I do try and choose lower-cost items when possible, and if possible bundle course sequences (Where a student would not take the first unless their degree program requires both) to save overall.

That is one advantage. For the formal course I teach, though, the homework grading comes at an additional cost (and it's pretty substantial). I think a few people have developed some open-source platforms that can do the same work, but I haven't investigated them.

MyOpenMath https://www.myopenmath.com is an option for online homework that is free.

Lumen Learning https://lumenlearning.com/courses/ also offers several math texts that include their online homework manager.

Unfortunately, both are limited to lower-level math courses.
