wifi technology cancer fear

  • readers might be misled into thinking that the scientific community or bodies such as the American Cancer Society are raising concerns about wireless devices. They aren’t.
  • the story made much of the fact that the International Agency for Research on Cancer (IRIC), part of the World Health Organization (WHO), classified RF radiation as a “class 2B”, or possible carcinogens. What the story doesn’t say is that same category includes pickled vegetables (some epidemiological studies link them to stomach cancer), Styrofoam cups, and coffee.
  • It’s not just that we don’t know exactly how RF waves would cause cancer. It’s that there’s no plausible way for it to happen without rewriting the laws of physics and biology. It’s by the same reasoning that most scientists dismiss homeopathic medicine – at least the genuine kind that’s so dilute there’s nothing in it.

  • Cell phone radiation is more powerful than that emitted by Wi-Fi devices and the predominant concern is brain cancer, since people tend to hold cell phones against their heads. If cell phones caused brain cancer, the scientists say, we should already be seeing an increase in overall cases. We don’t.

working memory learning support

    Remember the day when someone rattled off a phone number while you just hoped against hope you'd recall the string of digits as you were dialing? That was working memory toiling away. With the advent of cell phones, you may no longer use it this way very often. But working memory still plays a central role in learning and our daily lives.  If working memory is weak, it can trip up just about anyone. But it really works against a child with learning disabilities (LD). You can take steps to help a child with weak working memory, whether or not LD is a part of the picture. Start by understanding what working memory is all about.

    Throughout my nine years in the classroom, I've been eager to test out possibilities for improving teaching and learning through technology use. It's a messy process. Back in February 2010, I broadcast my eagerness to use cell phones in the classroom inEducation Week. Then I changed my stance, arguing in May 2012 that too much social media and gimmicky technology application in the classroom could lead teachers to neglect teaching students substantial skills. Since then, I've tested out Edmodo and continued to explore. After years of experimentation and reflection, here's my current take on smart-and not-so-smart-ways to use technology in the classroom:

    "A survey of teachers who instruct American middle and high school students finds that digital technologies are impacting student writing in myriad ways and there are significant advantages from tech-based learning. Some 78% of the 2,462 advanced placement (AP) and National Writing Project (NWP) teachers surveyed by the Pew Research Center's Internet & American Life Project say digital tools such as the internet, social media, and cell phones "encourage student creativity and personal expression." In addition: 96% agree digital technologies "allow students to share their work with a wider and more varied audience" 79% agree that these tools "encourage greater collaboration among students" According to teachers, students' exposure to a broader audience for their work and more feedback from peers encourages greater student investment in what they write and in the writing process as a whole. At the same time, these teachers give their students modest marks when it comes to writing and highlight some areas needing attention. Asked to assess their students' performance on nine specific writing skills, teachers tended to rate their students "good" or "fair" as opposed to "excellent" or "very good." Students received the best ratings on their ability to "effectively organize and structure writing assignments" and their ability to "understand and consider multiple viewpoints on a particular topic or issue." Teachers gave students the lowest ratings when it comes to "navigating issues of fair use and copyright in composition" and "reading and digesting long or complicated texts.""

    I love Instagram because it prompts me to take and share pictures of things that I might otherwise glance at then forget about. Before cell phones entered my life I rarely took pictures. Last week I took the picture that you see below. Almost as soon as it appeared in my Facebook feed via Instagram, my friend Kelly commented with, "shouldn't they be more concerned about weight than the number of people?" Kelly is a middle school math teacher so this picture was right in her wheelhouse of math prompts.

  • Boys are more likely than girls to report that they visit Facebook most often (45% of boys vs. 36% of girls). Girls are more likely than boys to say they use Instagram (23% of girls vs. 17% of boys) and Tumblr (6% of girls compared with less than 1% of boys).
  • As American teens adopt smartphones, they have a variety of methods for communication and sharing at their disposal. Texting is an especially important mode of communication for many teens. Some 88% of teens have or have access to cell phones or smartphones and 90% of those teens with phones exchange texts. A typical teen sends and receives 30 texts per day2
  • Teenage girls use social media sites and platforms — particularly visually-oriented ones — for sharing more than their male counterparts do. For their part, boys are more likely than girls to own gaming consoles and play video games.

    Very interesting statistics on American teens' use of social media and technology.

multitasking technology learning education students studying revision

  • “We were amazed at how frequently they multitasked, even though they knew someone was watching,” Rosen says. “It really seems that they could not go for 15 minutes without engaging their devices,” adding, “It was kind of scary, actually.”
  • media multitasking while learning. Attending to multiple streams of information and entertainment while studying, doing homework, or even sitting in class has become common behavior among young people—so common that many of them rarely write a paper or complete a problem set any other way.
  • But evidence from psychology, cognitive science, and neuroscience suggests that when students multitask while doing schoolwork, their learning is far spottier and shallower than if the work had their full attention. They understand and remember less, and they have greater difficulty transferring their learning to new contexts.

  • Under most conditions, the brain simply cannot do two complex tasks at the same time. It can happen only when the two tasks are both very simple and when they don’t compete with each other for the same mental resources. An example would be folding laundry and listening to the weather report on the radio. That’s fine. But listening to a lecture while texting, or doing homework and being on Facebook—each of these tasks is very demanding, and each of them uses the same area of the brain, the prefrontal cortex.”
  • Young people think they can perform two challenging tasks at once, Meyer acknowledges, but “they are deluded,
  • This ability to resist the lure of technology can be consciously cultivated
  • “The good thing about this phenomenon is that it’s a relatively discrete behavior that parents actually can do something about,” she says. “It would be hard to enforce a total ban on media multitasking, but parents can draw a line when it comes to homework and studying—telling their kids, ‘This is a time when you will concentrate on just one thing.’ ”
  • Stop fretting about how much they’re on Facebook. Don’t harass them about how much they play video games. The digital native boosters are right that this is the social and emotional world in which young people live. Just make sure when they’re doing schoolwork, the cell phones are silent, the video screens are dark, and that every last window is closed but one.
