A lecture is a method of teaching where an instructor presents information to a group of students. This format is commonly used in educational settings, such as universities and colleges, to convey knowledge on a specific subject. The lecturer typically speaks for a set period, often using visual aids like slides or videos to enhance understanding. Lectures can cover a wide range of topics, from science and history to literature and mathematics. They allow students to learn from an expert in the field and provide an opportunity for questions and discussions, fostering a deeper understanding of the material presented.
