classroom setting with three people

classroom setting with three people. One person is standing near the camera, looking at their phone and adjusting their hair. Another person is standing near a whiteboard giving a presentation, and a third person is sitting at a desk near a window, also looking at their phone. The classroom has rows of desks and chairs, a whiteboard, and a projector screen displaying a graphic of a light bulb surrounded by various icons. There's also a window that is letting in bright sunlight. The overall atmosphere appears to be casual and relaxed.
