Teaching tools
  • Rewards: Teachers can reward students with virtual credits, such as stars and trophies, for good performance during the class.
  • Pop-up quiz: This tool is applicable to scenarios where the teacher asks a single-choice or multiple-choice question and requests the whole class to answer the question together. The teacher can set up the choices and the correct answer, and then trigger answering. The teacher can see the number of students who have submitted an answer and the percentage that are correct in real time.
  • Polling tool: This tool is applicable to scenarios where the teacher wants to get feedback from the whole class. The teacher can set up the subject, choices, and start and end time of the poll. Flexible Classroom also provides live visualization of polling results.
  • Countdown timer: The teacher can find the countdown timer in the toolbox and set an initial value. After the teacher clicks the start button, students see a countdown window.
  • Breakout rooms: Supports the "breakout rooms" feature in small classrooms. Teachers can create breakout rooms manually (the teacher manually assigns students to each breakout room) or automatically (after the teacher sets up the number of breakout rooms, the system randomly assigns the whole class to breakout rooms). No matter which way the teacher chooses, a class supports up to 20 breakout rooms with a maximum of 17 members in each room. The features that are available in breakout rooms include real-time audio and video interaction, messaging, whiteboard, and screen sharing. After the breakout session begins, the teacher and teaching assistants have the ability to dynamically join or leave any of the breakout rooms. They can also send announcements to all the breakout rooms. Students are notified in their chat to check for the announcements.
