In the video, a man is standing in front of a classroom full of students. He is wearing a black sweater and a white cap. The man is pointing to a graph on a screen behind him, and he is speaking to the students. The students are sitting in rows, and they are looking at the man and the screen. The room has white walls and a whiteboard on one side. The man appears to be explaining something to the students, and he is using his hands to emphasize his points. The students are attentive and seem to be interested in what the man is saying.
