Autumn,
Another strategy you might want to use when checking for understanding is the student feedback method. I give each student a 3X5 card and have them write down, three things they learned during the class/lab or unit, two questions they have about the content, and one thing that surprised them about what they learned. Thus 3-2-1. When they are through I know that every student in the class has the six things written down so I can call on any student for a response without putting them on the spot. All they have to do is look at the card and read what they have written. This really helps my shy students to get involved in the course. Also, I learn based upon what they write and the questions they list what they know about the topic. I then can review the areas that need extra help as well as answer the questions they have listed.
