Banning smart phones in class is a no brainer if you want students to actually pay attention in class. But I’m baffled that they actually expected this ban to meaningfully improve test results.
Getting good grades involves doing your homework, prepping for tests, getting enough sleep to maintain your focus. All of which are done outside the classroom. If social media addiction is really the cause of plummeting school results, them banning phones inside the classroom is not going to solve the problem.
That’s like telling a junkie he can’t do drugs in class, but he can get his heroin back after school.
