What can be used to supplement a lecture and will allow students to process more information?

Visual aids significantly enhance the learning experience by engaging students in a way that spoken content alone may not achieve. They can include diagrams, photographs, charts, videos, or slides, which help illustrate complex concepts and structures. By providing a visual representation of the material, students can better grasp and retain information, as these aids cater to diverse learning styles.

For instance, a visual aid such as a diagram can clarify a previously abstract idea, making it more tangible. This combination of visual and auditory learning can lead to improved comprehension and retention of the material being taught. In contrast, while textual handouts offer supplementary information, they may not actively engage students, whereas practical examples can effectively demonstrate concepts but may not cover the breadth of theoretical knowledge. Extended essays go deeper into topics but may overwhelm students instead of supplementing the immediate delivery of key points during a lecture.
