Combining seeing and hearing leads to what percentage of retained information?

Combining seeing and hearing contributes to a significant increase in information retention, and research indicates that the percentage of information retained when both visual and auditory channels are utilized is around 50%. This dual approach engages multiple senses, which enhances the learning experience and facilitates better cognitive processing of the information. When learners can both see and hear information simultaneously, they are more likely to remember and understand the material, making the lesson more effective. This concept aligns with various learning theories that highlight the importance of multimodal learning for effective education and retention.
