Pros and Cons to the Hybrid Text

Here's a big question. Do we want a hybrid text? Or do we want a web book? The disadvantage to a hybrid is that it could be confusing for students to have two different places where they go for information. If we are going to do a combination, then we have to be mindful of this - I know that the preservice teachers I work with could get frustrated with when to use what text and why. This is an important aspect of our organization.
