classroom setting

classroom setting. A man stands at the front, lecturing. He wears glasses and a patterned shirt. He gestures with his hands as he speaks, at one point holding up a black item. The classroom has wooden desks and chairs. Several students are seated, listening and looking at their notebooks. A whiteboard is visible behind the lecturer, with writing on it. The classroom is lit by a ceiling light. One student is in the foreground, wearing a green shirt, with her back to the camera and her braided hair visible. The overall impression is that of a lecture or teaching session in progress.
