One major challenge in higher education is engaging student in the learning process, and this challenge is of particular concern in synchronous broadcast classes, where students are geographically dispersed. This paper argues that the use of online questions, that students can respond to using their electronic devices, is an effective way to increase student participation and engagement in such settings. Personal experience with one particular online question platform – Poll Everywhere (www.polleverywhere.com) – is used to illustrate potential capabilities, question types. Both advantages and challenges of using online questions are discussed.
