I disagree.
Great! But you have no evidence to support your argument. Your apples to oranges comparison of laptops isn't compelling. Nor am I compelled by your methodology argument, which seems to take issue with testing a hypothesis that phones are a distraction.
thought hitting was better than nothing even when they knew it was net harmful
Once again, we know cellphones are detrimental to learning. This is not a matter of schools failing to adapt to new technology. Tablets, computers, interactive software and more are used. It is about unrestricted cell phone use, which studies have shown hinders learning.
a phone ban in NY caused an increase in overall student obedience and educational productivity, ... Of course, this study does directly contradict your educatoronline article.
No it doesn't. It says that no phones mean better learning. You are missing the forest for the trees.
Crowd dynamics
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.
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.
One of the problems with arguing with people online is I tend to assume people are arguing in good faith.
After getting about 50 studies showing that cell phones are bad for learning, I switched to duckduckgo. Not until page 3 did I find your sources. You have waded through data that says you are wrong. I'm not interested in copying them for you.
