Imagine you are sitting in a lecture hall, receiving a lecture from your school teacher, a guest faculty or any other lecturer. The lecturer uses a wide array of engaging study material to augment the lecture. It may include presentations, videos, music or voices or simple pictures and charts. Modern lecturers often include the use of live working models to derive a better picture of the topic and supplement the information. The lecturers also interact with the students by the means of questions and answers to help the students clear their doubts and reach a conclusive understanding of the topic.
