One Minute Paper

One Minute paper is an idea that I ran across on the Internet. This is a method used by K-12 teachers to keep the students attention focused. They will introduce an idea or a topic. As students’ attention span wanes they hit them with a quiz. The site recommended making students write the question and answer. “The act writing will force the student to focus”.
This method was suggested for high school students. Freshmen college students are not that far out of high school so the method should work for freshman college (especially community college) econ classes.
This could be easily adapted to my classes. From time to time I ask students questions to check their understanding. I wait for them to raise their hand and respond. Sometime they sit and stare telling me that I need to approach the topic in a different way for them. I do this till someone raises his/her hand and give an answer that shows understanding of the topic.
Some of the students stare at me because they are confused and some stare because they have left the class. Instead of asking for a verbal reply I could write the question and giving them one minute to write a reply. I would give them 4 or 5 questions during the lecture. At the end of class where I usually review the main point, I ask them to exchange papers and I ask them to grade one another’s papers.
Should I give them the right answers? Or ask them to figure out the right answer? Maybe ask them to take it home and research the right answers as homework.
