Technology: can't live with it, can't get a recommendation without it

Last week I met my student teaching adviser, Dr. J, for the first time.  He will  observe me for a midterm (within the next couple weeks) and the final (in March).  He explained that I should use any and all technology in the lessons that he is going to observe. According to Dr. J, principals are looking for teachers that use as much technology as possible in their classes.  Dr. J will not write me a recommendation if I do not use technology. One of the most popular pieces of technology in the classroom is called a "document camera."  It's like a fancy overhead that projects anything you put under it (no transparencies needed!) It looks like this:

Although this device works in a similar manner to a traditional overhead, the biggest (and most annoying) difference is that the document camera needs to be placed in the middle of the classroom and not the front.  My back is turned on 1/2 the class and the other 1/2s back's are to me.  So I'm now expecting 25 five-year-olds to have the self control to pay attention to the image on the board and I can't even see 1/2 of them!  Today's addition lesson was NOT going well.  The kids were just not getting it.  I was freaking out because I could not get their attention.  I took a deep breath and realized that the biggest problem was the document camera.  I turned it off, and used the kids to make live addition problems in front of the class.  We wrote down our number sentences and the class was quite and attentive.

I was proud of myself for realizing that my lesson was suffering and I quickly thought of something else that worked, but now I need to find some way to use technology in a lesson...even though the lesson I thought of on the fly worked better than using the document camera.

Blah.
