The first automobiles were really horseless carriages, designed on the same frame as a horse-drawn carriage and with power defined in horsepower. The capabilities of these early contraptions were limited, and the infrastructure to support this new form of mobility was slow to develop as the early car owners rattled across the ruts and sank into the mud of unpaved and poorly maintained roads. These days, our society is built around the mobility provided by today's automobiles, and we are seeking to expand the infrastructure to accommodate battery-powered vehicles. How close is this analogy to the early stages of experimenting with cyberspace? I think the two stories are very similar, and I look forward to the day when the ruts in the cyberspace highway have been smoothed for a true community of learners to improve our world.

We're in the state once described by that great scholar of cyberspace, Manuel Castells, as "informed bewilderment".

The idea is that our short-term memory can only hold between five and nine "chunks" of information at any given moment (here a chunk is defined as a "meaningful unit"). So, when trying to decide how many big ideas about the internet would be meaningful for most readers, it seemed sensible to settle for a magical total of nine. So here they are.

On a scale of one to five! You have only to ask the questions to realise the fatuity of the idea. Printing did indeed have all of these effects, but there was no way that anyone in 1472, in Mainz (or anywhere else for that matter) could have known how profound its impact would be.

we need to help our students be more cyber smart and learn about why bullying is something to be taken seriously. It is never too early to educate our kids about the dangers of cyberspace.
