Which of the following is an example of a visual aid that can enhance lesson retention?

Charts or diagrams serve as effective visual aids because they can simplify complex information and present it in a clear, organized manner. Visual aids like these can help students to better understand and remember key concepts by providing a visual representation that complements verbal explanations. They engage students’ visual learning preferences, making it easier for them to recall the information later. For instance, a chart might illustrate a process step-by-step or compare data side-by-side, both of which can enhance comprehension and retention.

In contrast, short lectures primarily rely on verbal communication, which might not engage all learning styles effectively. Oral presentations also focus on spoken information and may lack visual support unless combined with visual aids. Text-heavy handouts can often overwhelm students and may not present the information in a digestible way, thus hindering retention rather than enhancing it.
