clueless???

I started reading the Asking Better Questions book and I feel like I  have been out there flapping when I have done my lectures.  The hands on part of my biology class has been fun--sorry--engaging.  The kids have been into that, but I have been getting yawns and the shut down looks when I go over the chapter/notes portion of the material.  I look forward to learning how to engage them fully and capture their interest--especially during the dry lecture part.
