What is the main purpose of using visual aids during lectures?

The main purpose of using visual aids during lectures is to enhance understanding. Visual aids can clarify and reinforce the content being taught by providing a visual representation of information, which can make complex topics more accessible and easier to grasp. For instance, diagrams, charts, and images can help illustrate concepts that may be difficult to explain with words alone. By engaging multiple senses, visual aids can also help maintain student interest and attention, leading to more effective learning outcomes.

Instructors use visual aids strategically to complement their teaching, not to overshadow it. They serve as tools to emphasize key points, encourage student engagement, and facilitate retention of information. This approach caters to different learning styles, ensuring that visual learners and auditory learners alike can benefit from the lecture.
