Hi Hengyu,
Thank you for your systematic description of multimedia learning. I quite agree with your description of the learning load. Everyone has a fixed amount of time to learn, and overloading often has a negative impact. This is one of the easiest things to overlook. Watching videos you upload shows that there’s only so much information your brain can process at any given time. So multimedia interactive learning can stimulate interest and keep the brain excited to learn more.
Proper rest is necessary. I look forward to conducting research and cooperation with you in this respect.
