This image presents a forensic view of an active classroom or lecture hall located in Fortaleza, Brazil. The environment features white walls and a light-colored tiled floor. The ceiling is white, possibly a suspended acoustic panel system, fitted with multiple illuminated linear fluorescent light fixtures. A white projector is mounted on the ceiling, directed towards a large white whiteboard at the front of the room. Rows of student desks with attached chairs, constructed from light-colored plastic (white or light grey) and black metal frames, occupy the space. At the front, a single brown office chair and a small table are present. A female instructor stands at the front of the room, near the whiteboard, facing the seated students. She wears a dark long-sleeved top with a light-colored print and is gesturing with her hands, indicating an active speaking role. Approximately ten individuals are visible, primarily students, seated in the desks. Most are oriented towards the instructor. In the left foreground, a student wearing a blue top sits with their back to the camera, hands clasped behind their head. Towards the center, two students, one in an orange top and another in a blue jacket, are also seen from behind. On the right side, a male student with a beard, wearing a black t-shirt and light-colored jeans, is seated, touching the back of his neck with his right hand while holding a black electronic device in his left hand. Various bags and water bottles are placed on the floor next to the student desks. A light blue door and a section of internal windows or louvers are visible on the right wall.
