The point is not just student-student introductions, they could do that without all the prompting, but that's boring and they already know each other. The overall point is to create an opportunity to be creative, to build a narrative for their imaginary travels, and to share knowledge with one another. I can't just tell them to do this; they wouldn't know where to start. The project is meant to provide them a framework to practice the grammar and vocabulary they've been learning, in a series of practical situations to roleplay. It gives them a chance to be partially responsible for the scenarios they will act out, as they choose what information to record about themselves and their cities.
As it stands, the project does require a lot of set up; the students need to know about the cities they're teaching each other about, and that knowledge (along with the information they've put into their own profiles) should provide them with enough material to keep the conversation flowing. Since the handouts set an important foundation for the roleplay later on, making sure the students understand their tasks is vital in the first steps.
This is the first time it's being taught, so I'm working out the bugs as I go along. What I meant with the glassy-eyed comment was that the kids in the beginning of the week are getting an untried, unpolished lesson, and I do indeed have a bad habit of over-explaining. It doesn't help that my 1st graders are generally lower-level and their behavior is poorer than last year's 1st graders; The older students are responding to it surprisingly well, and I'm excited to see how it goes for my friends teaching advanced groups. I think the higher the student's level, the more they stand to gain from this project. I might scale back the project for my 1st graders if I can't get them to complete the first steps in a timely fashion... it would help if more than half the class actually brought their homework with them.
