Classroom etiquette refers to the set of behaviors and practices that promote a respectful and productive learning environment. This includes being punctual, listening attentively when others are speaking, and raising your hand to contribute to discussions. It also involves respecting personal space and keeping noise levels low to avoid distracting classmates. Additionally, students should come prepared with necessary materials, such as books and writing tools, and follow the teacher's instructions. Maintaining a positive attitude and being open to feedback are also important aspects of classroom etiquette. These practices help create a supportive atmosphere for everyone involved in the learning process.
