The Cognitive Theory of Multimedia Learning posits that people learn more effectively when information is presented through both visual and auditory channels. This theory, developed by Richard Mayer, emphasizes the importance of integrating words and images to enhance understanding and retention. It suggests that our cognitive processes can handle multiple forms of information simultaneously, leading to deeper learning. According to this theory, effective multimedia learning involves principles such as coherence, which means avoiding extraneous information, and signaling, which highlights essential content. By following these principles, educators can design multimedia materials that align with how our brains process information, ultimately improving learning outcomes.
