As I continue working with more and more teachers I'm often surprised at how many I still see "page turning" to plan instruction. "Page turning" is a form of lesson planning that a teacher uses, that is simply opening a textbook and continuing where they left off during the last lesson. Now don't get me wrong, textbooks have their place in education (I guess), but when teachers rely on them too heavily instruction can suffer greatly, and more importantly, learning does too.
Here are a few reasons you should get textbooks out of your lesson planning and start forging your own instructional path, outside the edges of those pages.
Textbooks Fail To Engage Students
I don't care how many pictures or fun activities exist in the realm of the book you are using, I will almost guarantee that it is not engaging all your students. The simple reason is that the writers of that book don't know your students, YOU DO. I have never (and will never) heard a student mutter "Wow! Chapter 7 was surprisingly fun and exciting! I can't wait to continue working to Chapter 8!" I would bet that you haven't either. That's because textbooks are designed as a curriculum TOOL to be used in lesson planning, not a curriculum in themselves. Students must interact, play with, and experience concepts, not just read about them. (or hear about them during your lectures...which don't work either by the way.)
Textbooks Are NOT Universally Designed
Textbooks are generally written at or above the grade level you are teaching. The pictures, diagrams, and experiences presented in them are also created at that level. I don't know about you, but most of my students, or at least some of them, were below grade level or still achieving their current grade level. I would also like to suggest that the context, circumstances, and lens in which most textbooks view your curriculum are not going to engage or allow for much adjustment or modification if they are your primary lesson planning tool.
