READ TEXT III AND ANSWER QUESTION
TEXTO III
Digital Natives, Digital Immigrants
By Marc Prensky
What should we call these “new” students of today? Some refer to them as the N-[for Net]-gen or D-[for digital]-gen. But the most useful designation I have found for them is Digital Natives. Our students today are all “native speakers” of the digital language of computers, video games and the Internet.
So what does that make the rest of us? Those of us who were not born into the digital world but have, at some later point in our lives, become fascinated by and adopted many or most aspects of the new technology are, and always will be compared to them, Digital Immigrants.
The importance of the distinction is this: As Digital Immigrants learn – like all immigrants, some better than others – to adapt to their environment, they always retain, to some degree, their “accent,” that is, their foot in the past. The “digital immigrant accent” can be seen in such things as turning to the Internet for information second rather than first, or in reading the manual for a program rather than assuming that the program itself will teach us to use it. Today’s older folk were “socialized” differently from their kids, and are now in the process of learning a new language. And a language learned later in life, scientists tell us, goes into a different part of the brain.
There are hundreds of examples of the digital immigrant accent. They include printing out your email (or having your secretary print it out for you – an even “thicker” accent); needing to print out a document written on the computer in order to edit it (rather than just editing on the screen); and bringing people physically into your office to see an interesting web site (rather than just sending them the URL). I’m sure you can think of one or two examples of your own without much effort. My own favorite example is the “Did you get my email?” phone call. Those of us who are Digital Immigrants can, and should, laugh at ourselves and our “accent.”
But this is not just a joke. It’s very serious, because the single biggest problem facing education today is that our Digital Immigrant instructors, who speak an outdated language (that of the pre-digital age), are struggling to teach a population that speaks an entirely new language. This is obvious to the Digital Natives – school often feels pretty much as if we’ve brought in a population of heavily accented, unintelligible foreigners to lecture them. They often can’t understand what the Immigrants are saying.
