Classroom lectures are structured presentations delivered by a teacher or professor to a group of students. These sessions typically focus on a specific subject, such as mathematics, history, or science, and aim to convey important information and concepts. Lectures often include visual aids like slides or whiteboards to enhance understanding. During a lecture, students listen, take notes, and may ask questions to clarify their understanding. This format allows for efficient dissemination of knowledge to many students at once. Classroom lectures are commonly used in educational institutions, including high schools and universities.
