This image depicts the interior of a classroom, likely situated within the University of Trás-os-Montes and Alto Douro (UTAD) in Vila Real, Portugal. The room features light yellow walls and a ceiling with square recessed panels. At the front of the classroom, a large white board is visible, displaying handwritten mathematical equations, including expressions involving logarithms and roots, written in dark marker. A blonde-haired woman, dressed in a dark long-sleeved top and a patterned scarf, stands to the right side of the whiteboard, holding a dark marker in her right hand, actively instructing or writing. Four individuals are visible from behind, seated in blue chairs at white-topped desks, facing the front of the classroom and the instructor. In the central foreground, a person with long, dark, curly hair, wearing a light brown long-sleeved top, occupies a prominent position. To their left, the back and left arm of another student, wearing a light-colored top, are partially visible. To the right, the back of a third student, wearing a light grey long-sleeved top, is observed. Black over-ear headphones rest on the desk immediately in front of this student. The lower legs of a fourth person, clad in denim, are partially visible beneath the desk in the central foreground. On the left side of the classroom, a large window with green framing is partially open, revealing blurred green foliage outdoors. To the right of the white board, a rolled-up projector screen is affixed.
