Socrative is a free mobile app that engages students through interactive quizzes and assessments in real time. It allows teachers to anonymously poll students, move through questions, and get immediate feedback on student understanding. Students report feeling less anxious answering questions and find it easier to type responses. Using Socrative also saves paper and is more eco-friendly. While the basic version is free, a PRO version allows for more customization and features for larger class sizes.
