Well, this is no surprise:

“Remote learning poses a challenge for children’s behavioral health and functioning,” study co-author Emily Hanno told UPI in an email.

“This aligns with what we know about how stress and disruption affect children’s behavior,” said Hanno, a post-doctoral researcher at the Harvard Graduate School of Education in Cambridge, Mass.

Stress caused by “disrupted, uncertain and shifting routines” can impact a child’s ability to “interact positively with others and manage their emotions and behavior,” she said.

This is on top of demonstrably worse educational outcomes.  Time to stop the abuse.
