スマホで学力は下がるか

投稿者: 川口恭 | 投稿日時: 2017年02月19日 00:00

日本小児科医会と日本医師会が、『スマホの時間 わたしは何を失うか』という興味深いポスターを作ったらしい。


記事で歯画像が小さくてよく分からないので、現物を見ようと思って、日本医師会と日本小児科医会のサイトを眺めてみたが、現時点では両方とも何も出ていないようだ。


そんなに間違ったことを書いてあるわけではないと思う。問題提起も必要だろう。ただ、どうしても特に「スマホを使うほど学力が下がります」は、明らかに相関関係と因果関係の混同があり、表現としてマズかろうと思う。


スマホをメリハリなく長時間使ってしまう背景事情もあるはずで、「スマホを使う時間が長い人ほど、学力は低めです」で、なぜいけなかったのだろう?

Great blog! Do you have any tips for aspiring writers?
I'm hoping to start my own site soon but I'm a little

a free platform like Wordpress or go for a paid option? There are so many options out there
that I'm totally overwhelmed .. Any recommendations?
Cheers!
