The video shows a classroom scene. There are two students in the foreground, one wearing a white shirt and the other wearing jeans and a white shirt. A teacher, wearing a blue shirt and black pants, is standing in front of a whiteboard and writing on it with a marker. A portrait of a man in a red shirt hangs on the wall above the whiteboard. To the left of the whiteboard is a projection screen displaying text and formulas. A tablet is on the desk in front of the student in the white shirt.
