Why Reading Matters is an hour-long BBC program did a couple of years ago on how reading — and writing — impact the brain.
I wouldn’t show the entire show to students, but there are several very good segments.
The entire show is available on Vimeo, which I’ve embedded below, and it’s also available on YouTube, though it’s in six separate ten minute segments. I’ve also embedded the first segment below.
I’m adding the videos to The Best Resources For Showing Students That They Make Their Brain Stronger By Learning.
