I teach US History in a parochial school and they don't like to do anything that requires thought, either. It drives me crazy. Actually, the book discussion, worksheet, and test is an EASY way to teach. It is not any easy way to LEARN!
Like it or not (on their part) they have to learn how to use primary sources, read political cartoons, and analyze. Graphic Organizers help them sort out and organize information. So do not stop using them.
Basically they are making very poor choices and of course their scores show it. I got angry one time and gave them a choice of the book/worksheet/test option with a grade no higher than a C or going "my way". The majority of the class chose the simplest way out. I sent a letter to the parents explaining the choices and the choice their child made. I stated that the majority of my time would be spent with the group that actually wanted to LEARN history. If this was acceptable to them, to sign and return. I actually had two parents sign it. The others were told by their parents to get with the program.
Here is a good site for teaching:

Do you have the computer program "Inspiration" on your computers? Kids often enjoy doing graphic organizers with that program.
I wish I knew the magic way to "fix" apathy.
