As many children are homeschooling, we have created a new facility for teachers to be able to stream lessons and be able to answer questions via live chat.
Teachers can broadcast lessons from anywhere, be that school or home. They can broadcast voice and video of themselves or just share a screen to explain a certain topic.
With the ability to post a YouTube video instead of a live stream, you also have the flexibility to engage with the audience on another level.
Use the system for lessons for individual classes or pupils, maybe even the morning school prayer or just leave it live for the school day so as pupils can ask questions.
