لیکچرز (lectures) are structured presentations given by educators or experts to convey information on a specific subject. They are commonly used in academic settings, such as universities and colleges, to teach students about various topics, including science, history, and literature. Lectures can be delivered in person or online, often accompanied by visual aids like slides or videos to enhance understanding. During a lecture, the speaker typically presents key concepts, theories, and examples while encouraging audience engagement through questions or discussions. This format allows for the efficient dissemination of knowledge to a larger group, making it a popular method for teaching in both traditional and modern educational environments.
