Great! But you have no evidence to support your argument

I cited two pieces of fairly substantive evidence in reply to someone who cited a single article. If you don't think that is reasonable escalation of evidence, we can stop now.

Once again, we know cellphones are detrimental to learning. This is not a matter of schools failing to adapt to new technology

My cited references contradict that. More importantly, your article contradicts the "we know" part. Let me quote your reference: "Research from Sweden, however, suggests little effect of banning mobile phones in high school on student performance. "

My references made clear argument that this is indeed a case of schools failing to adapt to new technology. I even quoted a relevant quote to you.

No it doesn’t. It says that no phones mean better learning. You are missing the forest for the trees.

"My findings suggest an improvement in educational productivity due to the NYCDOE’s ban removal". I understand there's a double-negative in that reference, but the cited study's findings suggest that "yes phones mean better learning". You might disagree with it, but please reread it so that you do not misrepresent it.

Lots of research has been done on this, and a small number of people can influence a large group. Look at “wave” studies for more info.

Sure. Please demonstrate that your claims are correct. Until then, and especially because you seem to have failed to comprehend the involved references, I will wish you luck.

Calling minimum acceptable classroom behavior “picking yourself up by your bootstraps” is absurd. It’s like saying that you can’t expect people to not talk at the theater because that’s just asking too much of people.

I've lived an entire life of watching people blame the bulk of individuals for failures by authorities. I have become reasonably skeptical of any claims that "it's everyone but..." the decision-maker.
