  Abstract: A popular type of question in online homework involves a set of several true/false statements where students must submit their answer to all the statements at once. This discourages random guessing because although one true/false statement has only two possible answers, a question containing N such statements has two raised to the Nth power possible answers. We have studied student response patterns to a number of these questions with the goal of determining which of the individual true/false statements exhibit a large proportion of response switches (i.e. from true to false or from false to true) and which statements exhibit largely consistent responses. The tendency of students to change their answer to a statement or to remain consistent is one indication of student confidence in the knowledge tested.
