There is a girl standing in a classroom with a tablet

A teacher stands in front of a high school classroom, explaining a concept on black or white board. She is standing, with an attentive and engaging expression, wearing professional and comfortable clothing. The students, sitting in rows of desks, are attentive, with open notebooks and pens in hands, some taking notes while others look at the teacher. The classroom is modern, with large windows that let natural light in, and decorated with educational posters and a bookshelf in the background. The atmosphere is one of learning and concentration, with the teacher using gestures to illustrate her explanations. Add details like backpacks on the backs of chairs and smartphones on tables to reflect the reality of high school students
