So what makes a good lesson/teacher?

I observed Mark's teacher today because I had a sub. Mr. D is so animated and dynamic. He jumps on top of one of the desks and dances around the room, shouting and making strange sounds. Wow! He is getting into the content, making high level connections and seems to have a Phd level of knowledge. I'm impressed with his charisma, and on the surface it looks like excellent teaching, for sure. I remember when I was a confident teacher and my personality showed through and I was able to engage students and give my lessons a personal touch. But are his students learning anything?! Well, I'm not sure. When I measure his lesson up against the framework that I received last night in class, I'm not so sure the students have the content. I circulate the class and find that some students have filled out the graphic organizer on the causes of the crusades while others have barely made a dent in it. I guess that's the honors way of doing things, you either sick or swim, and no one is there to make sure that you have it. By "it," I mean whatever the point of that lesson was.
