three people, likely in a classroom setting. Two students are sitting at a desk, while an adult male stands in front of them, presumably teaching or lecturing. The students are focused on their notebooks, which appear to contain handwritten text. One student is wearing a yellow shirt and leaning on the desk with his head resting in his hand, but looks up at the camera and smiles. The other student, wearing a red shirt, is looking down at her notebook. The teacher is wearing a plaid shirt and jeans, gesticulating while speaking. The classroom has a green chalkboard with a drawing of a drum or bucket on it. The desks appear to be old and made of wood. A blue pen is visible on one of the notebooks.
