Student Response Systems (SRS) can provide effective, immediate, and efficient feedback to students, particularly when undertaking formative assessment. Coupled with active learning approaches, the use of such systems can be beneficial for English language learners by providing opportunities for increased engagement with content and reflection on their knowledge gaps. These opportunities can then potentially lead to increased learner participation, motivation, and linguistic skill development. As an SRS system, the pedagogical practicality of using and developing content with the "Plickers" application is reviewed, with features of the application presented in detail. Methods of applying the application, determining how it aligns with technological frameworks, and presenting the potential of the application for use in the language teaching context are also presented. Ultimately as a tool that can be used to engage students of all ages in formative assessment, it is unique in that it can do this by taking technology out of learner hands while simultaneously assessing all students at once.
