I found this layout very impressive. The teacher is apparently sitting in front of a green screen, and is somehow merging that with his white board. Note how there is no box around his head and shoulders! That’s the sign that this is a green screen. Obviously, he is not in front of a real blackboard. He is writing using either a graphic pen, or his mouse, and what he writes appears on the simulated chalkboard. Then he can also share his screen on the same board.
