A lot of the hearing appears to have been about screen time in general. The 4-5min segment that I listened to and am reporting on was specifically about the use of technology in school (starting in 2010)correlating chronologically with the first ever decline in the cognitive ability of Ameriucan children (GenZ). This held through 80 countries, 5 hrs or more in school, 2/3 of a standard deviation drop. The last portion talks about why screen learning doesn’t work.
I posted this because it raises the alarm on computers being used in schools to substitute for classroom instruction.
I would agree that computer learning is not as effective as books, pencil, paper, and in person. It’s a lazy substitute.
