engineMiddle school students can encounter problems when researching on the web. This can lead to wasting a great deal of time and energy. Here are some tips that should make the job much easier.

1. Spell keywords properly.

2. Choose strong keywords. For example if you were trying to determine what turtles eat, you may want to use turtle and diet as your keywords. Example: If you want to buy a car, don’t enter the keyword “car” if you can enter the keyword “Toyota.” Better still, enter the phrase “Toyota Dealerships” AND the name of the city where you live.

3. More keywords narrow your focus. Poodles black quiet “for sale” will result in fewer hits.

Web Searching 201

Lost in the mazeWay back in October, I wrote a blog entry called Web Searching 101, outlining some basic web searching tricks using Google, but mentioned that some techniques work better with other search engines, for example AltaVista, and I promised to write a follow-up, Web Searching 201. Better late than never, so here goes…

A simple Google search may appear to give you the most relevant hits first, but that is not necessarily the case. A number of techniques can be used to (artificially) improve a site’s page rank, i.e. how high on the list of hits it appears. For companies with an online presence, getting a high page rank has enormous potential to increase traffic to their site and thus (hopefully) boost their business. Not surprisingly, SEOs (Search Engine Optimizers) are in high demand these days.

Most often, when Internet users do a web search, they just choose one of the first few links that appear and don’t even bother going to the second page of hits. In some cases that’s fine, but they should be aware that a carefully crafted search algorithm has determined the order of the results you get, thus the results necessarily contain a certain bias.

All Internet users will benefit from learning how to formulate search criteria to target their search more carefully, and this is something we all ought teach our students specifically before sending them to the lab to do research.

Here are some powerful ways to get a lot more out of your web search engine. (Note: all these examples are for using the search engine http://www.altavista.com.)

The times they are a-changin’

Over the last few months, the strike of the Writers Guild of America has led to a significant shift in viewership from TV to online media, as more and more people got fed up with re-runs of old series. Blogs, podcasts and video sharing sites are among the online media outlets benefitting from the TV exodus.

I’ve been writing a few things lately about the Internet as a tool for collaborating and connecting minds, both in terms of expanding educational opportunities and in the context of skills our students will need in the future. I’d like to explore another aspect of that for a moment…

I believe networked collaboration tools can serve a crucial role in other ways as well: as collaboration tools for social improvement. During the Long Now conference earlier this year, author Paul Hawken spoke of the emergence of what he calls ‘the largest movement in the world’: countless organizations working in decentralized unison to restore the environment and foster social justice.

Social bookmarking - ever heard of it? It’s yet another example of a powerful new way of collaborating. In the immortal words of Herry Monster, two heads are better than one. Here’s why and how…

Internet usage statistics for ISM

On Tuesday morning, Mark and I did a presentation for K-12 parents on the topic “The Internet, you, your child: why can’t we all just get along?”, where we shared survey data from Mark’s MS classes on Internet usage, responded to questions from the audience and also shared a good video explaining Social Networking. It was a good talk, with lots of interesting questions. A lot of the questions centered around Facebook, which the vast majority of the HS students are using. Many parents were concerned about their students not using the privacy settings in Facebook.

Mark Granovetter introduced more than thirty years ago the notion of “the strength of weak ties” - the idea that for many purposes, a large network of loose connections can be more useful for meeting many of your needs than a small network of close connections, e.g. for finding a job. This may seem counter-intuitive, but just think about it: there is typically a relatively large overlap between your network of connections and those of your close friends or family members. You already know or regularly interact with many of the same people, and it’s probably unlikely they’ll be able to pull out of a hat a connection to a person you don’t know, who possesses just the skills or resources you’re looking for. A former colleague who’s since moved on to a new occupation, however, is probably more likely to know new people and be able to put you in touch with what (or who) you need.
