What is the main benefit of using both visual and verbal instructions in teaching?

The main benefit of using both visual and verbal instructions in teaching is that it leverages the principle of dual coding, which enhances understanding and retention of information. When information is presented in both visual and verbal formats, it provides learners with multiple channels to process and encode the information. This dual representation helps in creating stronger mental associations and facilitates recall.

By combining visual aids—such as diagrams, charts, or images—with verbal explanations or narratives, educators can cater to different learning styles and improve overall comprehension. This approach recognizes that people process information differently and supports the idea that presenting content through various modalities can lead to a more comprehensive understanding of the material.
