When learners both hear and see information, what percentage do they typically retain?

When learners are presented with information using both auditory and visual modalities, they typically retain around 50% of what they learn. This dual-channel approach enhances learning effectiveness because it engages different pathways in the brain, reinforcing the material through both sight and sound. By incorporating dual sensory input, learners can connect concepts more readily and improve their retention rates. This principle highlights the importance of varied teaching methods in facilitating better learning experiences.
