One piece of technology I think every teacher should invest in are flip cameras. They literally can serve a great purpose in the classroom and save so much time when it comes to individual assessment.
I have used flip camera for recording skits, interviews, conversations, or just a quick impromptu reply from my students. I think it's important to have an oral assessment with every unit. The kids need to know that they HAVE TO KNOW how to say it. Isn't that the point of being able to speak a language?
Anyways, one activity I do which is quick and simple is I get a can (I have several of them). I got them for a 1.00 at the dollar store and I bought around 10, cut up questions pertaining to the current unit we are working on, and a put a camera in the can as well. I divide the class into groups...usually 5 to 6 groups. I tell them one person come get a can and then to scatter....some go in the hall, some in the back of the room, some in the front, etc. I tell them to record everyone pulling a question and asking the question on demand.
Afterwards, I take up the cameras, plug them in, get my grade book and just go down the list grading oral responses right then and there. No pulling each one out in the hallway or figuring out how I am going to get to every kid. :)
