Cold Call
"Ask a series of short, pre-planned, open-ended questions to a strategic sample set of the class. It is helpful to choose a few key points in the lesson to conduct a general assessment of student understanding before moving on. Do not ask for volunteers. Cold call on students at varying ability levels, and ask a series of short questions to probe for understanding, such as the exchange below. Note that for questions to be targeted, they should be written in advance:
OK, let’s make sure we’re clear on the differences between plant and animal cells. Jason, what does the presence of a cell wall tell me about a cell? ... Good, and what else might tell me I’m looking at a plant cell, Charlene?... And which cells have chloroplasts, Jose? ... Yes, and why do they have them, Sasha? ... Good, we’re ready to move on."
