Which of the following is an example of a student response system?

A student response system, often referred to as "clickers" or "audience response systems," is a tool that allows instructors to gather real-time feedback from students during lessons. These systems enable students to respond to questions or polls using handheld devices or mobile phones, with results being displayed instantly, fostering interactive learning and immediate assessment of understanding.

This interactive component is vital for promoting engagement in the classroom, as it encourages all students to participate and provides teachers with instant feedback on student comprehension of the material. Other options do serve educational purposes but do not function as real-time response mechanisms in the same interactive way. For instance, discussion boards allow for asynchronous conversation but lack the immediacy of student response systems. Learning management systems (LMS) provide a broader range of functionalities, such as hosting course materials and assigning grades, but they do not specifically focus on real-time student feedback during lessons. Online quizzes can be useful for assessment but do not inherently facilitate the immediate back-and-forth interaction characteristic of student response systems.
