Video lectures are recorded presentations that allow educators to share information with students through visual and auditory means. They can cover a wide range of subjects, from mathematics to history, and are often used in online courses or as supplementary material in traditional classrooms. These lectures typically feature a speaker, often a professor or expert, presenting content alongside slides or visual aids. Students can watch these videos at their own pace, pausing or replaying sections as needed, which enhances their understanding and retention of the material.
