Student response systems (SRS) or clickers have become the norm in K-12 classrooms as an assessment tool as well as a means to increase class participation. Like most technologies, there are varying platforms and manufacturers of SRS mobile devices ranging in cost from approximately $1500 to $3000. In spring 2010, Microsoft launched a free PowerPoint add-in program called "Mouse Mischief." This free download, coupled with wireless mice, enables users to deploy twenty-four wireless mice across the classroom enabling students to respond to varying question formats from their desktops at a substantially lower cost than traditional systems. The following research study focused on K-12 classroom implementation of this newly released version of an SRS, which is distinctly different from the other variations currently available.
