school is place to learn 2 things:
- proper social interaction and becoming a responsible adult.
- essential knowledge and skills before you branch out and find your thing to earn your own meals.
And IMO, the first point is way more important than the second. Let's see the implication by breaking down the proposed ban.
From the anti-bullying side:
- deterrent tool is taken away
- bully now have a "safe" grey area to do their thing and become he says/she says.
- teachers or admins could not keep eyes on everyone, and some of them don't care if there are no bodily harms happened.
- you know how much teens will listen to what adults said, even with laid out consequences.
From the learning, focus during instructional time:
- I grew up without any gadgets(45yo) so no gameboy until I was at high school. Everyone still found ways to distract themselves from boring classes.
- for schools without student chromebook/laptop/tablet, you lose a big chunk of diversity in "asking questions" or "find alternatives". aka, I feel teacher said something off, how do I find something to support my talking point or argument? Fact checking, math checking, etc.
- The guys that are not interested in your material and have nothing to distract themselves with will just stare at something they interested in or day dreaming stuff. It will not help average score or engagement.
For engagement, from my old self and what my friends here from different background/countries/age bracket discuss their past, the one common thing is fun knowledgeable teacher and how enjoyable their class was last life time long. It shapes their understanding, how they engage other people or topics involving different areas. kids and teens are like herds of fun chasing animal, if even half of your class is having fun and discuss the materials and exchanging questions etc, the rest will follow cause they don't want to be "left out".
In short, if a teen can learn how to calculate DPS and build sets for their favorite game but fails the math about probability and expected value, the teacher is doing something wrong.
