Plickers serves as an effective formative assessment tool in the classroom, offering a simple and efficient way to gauge student understanding. The key feature of Plickers is that students don't need individual devices; instead, they use printed QR code cards. The teacher poses multiple-choice questions, and students respond by holding up their unique QR code card with their chosen answer. Using a single device equipped with the Plickers app, the teacher scans the room, instantly capturing and analyzing student responses. The platform records individual performance, allowing educators to assess comprehension, identify areas of difficulty, and tailor instruction accordingly. Plickers' seamless integration into the classroom facilitates quick and regular check-ins on student progress, making it a practical and accessible formative assessment tool.
