Carr shares that since the 1980’s many have thought that introducing hyperlinks into text would increase learning, improve critical thinking, etc. Hyperlinks would allow the reader to more easily switch viewpoints. Researchers have learned though that there is a lot of overhead to evaluating hyperlinks, deciding to click or not, etc. It creates a lot of disruption for the reader, reduces comprehension, and memory retention.
“The Internet is an interruption system. It seizes our attention only to scramble it.”I’ll leave it to you to read the entire article – worth your time in my opinion. It made me think about my own interactions with technology. On a given work day when I am on my computer, I have e-mail, twitter, telephone, instant messaging (IM), cell phone, skype, all active. Messages keep coming in, causing interruptions. I do find myself often taking the easy out – read the email, check twitter, and of course respond to the IM (it must be instant) – rather than focus on developing that presentation, writing that report, analyzing the budget, brainstorming goals and priorities, preparing for the meeting, etc. Multitasking right? Or is it just a relentless barrage of distraction and interruption? Carr says,
“Media multitaskers are suckers for irrelevancy: We are training our brains to pay attention to the crap.”Hmmm, that sure is true when you think about how many messages from the various inputs you have, are useless time wasters. Each one takes processing time for our brains to evaluate and accept or reject. We can’t get that processing time back! Carr suggests we are overloading our brains – what might be the long term affect of that?
Thinking about student learning, there seems to be a believe today that kid’s brains, these digital natives, are wired differently and that they can handle all the inputs / outputs (IM, facebook, twitter, texting, music, videos, etc.) coming at them while doing homework, studying, etc. Maybe they are wired differently and can do these things, but we should ask the question “at what cost” to true learning?
I think the adults in their lives need to help kids manage this reality. Kids may think they work better with all the distractions but that doesn’t mean it’s good for them. Common sense might tell us that focus time is important some of the time. We humans need to turn off the distractions at times to think more deep. We need balance – broad inputs are important but so are deep ones. Purely shallow knowledge and thinking is insufficient for true learning. Just look at an accomplished athlete – when they are focused and producing, most other inputs are turned off. Adults still need to teach kids “how to drive”…
Our schools are wrestling with the deluge of personally owned devices (POD’s) entering their buildings. Most middle schools in our District require kids to put their PODs in their lockers. Some middle schools though are exploring how they might leverage PODs for learning. I think this is a very important point in time for schools to make sense of this. It will be important that the use of PODs is carefully managed. I think they will likely need to be powered up and down through-out the day depending on the learning activities students are engaged with. There is a lot for us all to learn about how to deal with the chaotic information and device world we live in and how to take best advantage of it for our learning and work. In spite of the “dangers”, I am a firm believer that technology, used effectively and not allowed to run our lives, proves to be an amazing learning, engaging, efficiency, creative, … tool for all of us.
I’m curious what others think about these ideas. Feel free to share your views with me here.
