Survey reveals what 8+ hours of screen time does to students’ grades

“What effects can phone screen time have on students?” OneClass reports. “At first glance, it may seem harmless but when we decided to take a closer look, we found a strong correlation between too much phone time and lower grades.”

“We asked 875 undergraduate university/college students (1st year students aged 17-19) what their daily phone screen time was the last 7 days and their current grade to see if there could be any correlation between them.,” OneClass reports. “We found that 83% of respondents used their phone for at least 3 hours, while only 17% used it for less than 3 hours… Furthermore, the most uncommon screen time was 0-1 hours which only 1% of respondents selected.”

“The lowest overall grade for those who have 0-1 hours of screen time is a B- compared to a D- for those who have 8+ hours of screen time,” OneClass reports. “So, the answer to ‘does phone screen time affect grades?’ is yes, it’s one factor that can negatively affect grades but it isn’t the only one, nor is it a direct causation, but rather a correlation. Instead, the conclusion is that phone time significantly increases the possibility of getting a lower grade due to the increased variability that more phone time brings.”

MacDailyNews Take: This is something the visionary Steve Jobs seems to have known instinctively from the get go:

In September 10, 2014, The New York Times‘ Nick Bilton recounted a conversation he had with Steve Jobs in late 2010:

Bilton: So, your kids must love the iPad?
Jobs: They haven’t used it. We limit how much technology our kids use at home.

“Since then, I’ve met a number of technology chief executives and venture capitalists who say similar things: they strictly limit their children’s screen time, often banning all gadgets on school nights, and allocating ascetic time limits on weekends,” Bilton reported. “I was perplexed by this parenting style. After all, most parents seem to take the opposite approach, letting their children bathe in the glow of tablets, smartphones and computers, day and night.”

Bilton reported, “Yet these tech C.E.O.’s seem to know something that the rest of us don’t.”

    1. Trump’s inability to assess all favts, not just the isolated few that he can politically exploit, is evident for all to see. Before the morning newspaper hits the stand, he’s tweeting trash talk about whoever he can attack today.

      Makes you long for the days when press events were as respectful as that portrayed in Roman Holiday …..

  1. Adults should indulge themselves of the most screen worthy creation of them all, an incredible work of art from moi- the most modest and creative artist of the 21st century

    You know it’s my work because the frog says “ding ding” which I ensured was a brilliantly clever play on my name, Dingler.

    I’m so, so proud of just how crazily clever I was and of course continue to be. You can count on your great countryman, John Dingler, artist.

  2. OR….it could be that students who were on their phone for higher amounts of time were simply less committed to their education and would have gotten lower grades anyhow. Let’s not forget…data can be made to say whatever result we may want. Did the survey query all earlier GPAs/grades?

    1. I work every day with a genius IQ level who would, if allowed, play screen games and watch utube videos about gaming for at least 20 hours a day. He is capable of calculating in his head numbers in the trillions easily. He has a dopamine addiction because of his gaming. He will never be able to work in a job or live independently. Simple things like cooking, laundry, has never written a check, driven a car, and actually has trouble formulating and typing in an internet search, has no firm idea of what his parents address is, or their phone number.

      “Would they have gotten better grades if they had spent that time hanging out at the mall or in a bar?”

      Yes, without a doubt.

      “visiting lonely elderly people” he would literally never consider doing that unless they agreed to talk about his games. THIS IS NOT AN EXAGGERATION!

      Think what you want, tell me I am making all of this up. YOU ARE WRONG.

      One other thing, a friend who has a company that supplies physical therapy services to 2 Olympic teams recently sent me a photograph of 7 young males who are apparently going to make up a proposed Olympic gaming team! They “practice” 16-20 hours per day! They all had the exact expression and eyes, indicating SEVERE autism. She said that she would absolutely decline to provide any services to them, should they unfortunately end up in an Olympic “sport” at the risk of losing her contracts.

      Believe me or not, I don’t care.

  3. Profoundly stupid and ridiculous!!! Would they have gotten better grades if they had spent that time hanging out at the mall or in a bar? Or working at Amazon stocking shelves? Or doing nice charity work like visiting lonely elderly people? Or delivering meals on wheels? “Screen time”, as such, is irrelevant.

  4. Harvard Medical School analyzed the screen time and the brain activity dependence – anxiety is the first side effect. Besides, the American Academy of Pediatrics set a new standard of screen time rules for kids too that can help avoid obesity: 1 hour per day.
