Clickers are handheld devices used primarily in classrooms and large group settings to facilitate audience response. They allow participants to answer questions or polls in real-time, providing instant feedback to the presenter. This technology enhances engagement and interaction, making it easier for educators to gauge understanding and adjust their teaching accordingly. Typically, clickers operate using radio frequency or infrared signals, transmitting responses to a receiver connected to a computer. Many educational institutions utilize clickers as part of their student engagement strategies, promoting active learning and participation. They are often integrated with learning management systems for seamless data collection and analysis.
