If students are talking amoung themselves and you notice the topic slowly moving towards gripping about the school or program and then other students start listening in and adding to the whining, what is the best way to intervene?
This is in a lab class where students are allowed to be social with one another as long as they are doing the tasks assigned to them. Also, during open lab time, when no formal class is going on and I am just sitting in to assist students.
