BOX 2.2 What Expert and Novice Teachers Notice Expert and novice teachers notice very different things when viewing a videotape of a classroom lesson. Expert 6: On the left monitor, the students' note taking indicates that they have seen sheets like this and have had presentations like this before; it's fairly efficient at this point because they're used to the format they are using. Expert 7: I don't understand why the students can't be finding out this information on their own rather than listening to someone tell them because if you watch the faces of most of them, they start out for about the first 2 or 3 minutes sort of paying attention to what's going on and then just drift off. Expert 2: . . . I haven't heard a bell, but the students are already at their desks and seem to be doing purposeful activity, and this is about the time that I decide they must be an accelerated group because they came into the room and started something rather than just sitting down and socializing.   Novice 1: . . . I can't tell what they are doing. They're getting ready for class, but I can't tell what they're doing.   Novice 3: She's trying to communicate with them here about something, but I sure couldn't tell what it was.   Another novice: It's a lot to watch.
