Students typically use electronic polling systems, or clickers, to answer individual questions. Differing from this tradition, we have developed a new clicker methodology in which multiple clicker questions targeting the same underlying concept but with different surface features are grouped into a sequence. Here we present the creation, validation, and evaluation of clicker question sequences sufficient in number to populate a year of calculus-based introductory physics.

Most of the material covered in voting machine questioning was covered by lectures in the non-voting machine classroom. This statement was validated by observing clicker and non-clicker lecture sections for several quarters. Because most of the same material was covered for an approximately equivalent amount of time, “small percentage” specifically relates to the mechanics of taking a vote, typically 10% of lecture time.
