ConcepTests (clicker questions) for science and math classes


Dwain Desbien and Brant Hinrichs, expert modelers, use ConcepTests by Eric Mazur (at Harvard University) in their college Modeling Instruction.  Below are weblinks for ConceptTests in physics, chemistry, earth science, & calculus. All URLs work as of Feb. 2013.

Six long webpages that tell you all about concepTests in any science.


Carl Wieman’s webpage has many resources.


ERIC MAZUR’s physics clicker questions/ConcepTests are at

Interactive Learning Toolkit:


Eric Mazur developed them by using wrong answers to short answer questions on quizzes and tests as his distractors for clicker questions. He did this systematically over the years.

CALCULUS, PHYSICS. Also, articles on ways to use ConcepTests in math and physics.

Warning: Eric Mazur's Galileo website was hacked, so the galileo weblink no longer works.

His replacement weblink as of summer 2011 is

Interactive Learning Toolkit (ILT).  "Administer your courses, design course Web pages, and interact with your students online."  "The ILT-BQ software allows to upload ConceptTests prepared within the ILT to BQ and to return the student responses to the ILT for statistical analysis of the data and the tracking of individual student performance."

I quote Paul Hewitt:

     Next-Time Questions are favorite insightful questions I have asked my students over my teaching career. I have embellished them with cartoons "to catch interest. Their intention is to elicit student thinking. My use of them was posting several in a glass case outside my lecture hall-without answers. The wait-time for answers was one week. I could have called them Next-Week Questions, which would have been more appropriate.

     Most of these have been published over the years as Figuring Physics in The Physics Teacher magazine. They have also been in ancillaries to my Conceptual Physics textbooks, and physical science textbooks as well. My hope is that teachers will pose the questions, and withhold answers to "next time," which could be as early as the next class meeting. Their educational value is the long wait time!"


Thanks to modeler Geoff Schmit for posting comments about these, in his blogpost on Sept. 26, 2011:
