Re: An interesting thought for the teachers out th

There is no telling the accuracy of the information the kids may come across out there. Lord knows what they would find ....
One of the great difficulties we have with our undergraduate students is an inability to discriminate between well founded arguments and solid facts and spurious information and unsubstantiated opinion.
Too many of these students think they can do a little surfing and uncover everything that's important or relevant, cut and paste and edit it all a bit and have done a good job.
What the web cannot teach (and often seems to obscure) is critical thinking and analysis. A Google search can turn up literally millions of hits without discriminating between those that are trivial, duplicates, unfounded; and just plain rubbish.
And a critical failing can be the inability amongst those millions of hits to trace any particular "fact" or assertion back to its source for documentation or to investigate its validity or reliability.
As a trivial example I looked at Wikipedia and for some reason was looking at what it said about dual over-head cam, 4 valves per cylinder engines and saw that the entry claimed this type of engine was first used in a production car in the Triumph Dolomite. That's wrong, but no one else had corrected it. The Jensen-Healey beat Triumph by a few months into production using its Lotus 907 engine. A very trivial example, but illustrative. I entered a correction, but there's absolutely no other validation or consistent review. Who's checking that I'm right?
And the web can seeming validate majority positions, or vocal opposition simply from the volume and/or strength of opinion. At some risk of veering into political territory consider any controversial subject (like evolution) and juxtapose the two positions seen on the web against those same positions in any scientific journal or textbook.
And not everything has been digitized, so anyone that relies entirely on the web cannot access vast amounts of relevant information that's available from books or other published sources. For many students reliant on the web, anything only in the print media simply doesn't exist. Or is thought too hard to bother with.
I like these tools and use them a lot, but... they have some very significant flaws as sources of information and inexperienced students often fail to understand, or even grasp those deficiencies.
Perhaps my greatest concern is that students are becoming even more addicted to "sound-bite" information. A good, solid book can take days to read and understand well; and may even require re-reading. A task that's all but impossible for web sources unless they ownload the hard copy- and then the web becomes a distribution mode- allbeit a very effective one.
A student a couple years ago asked "Which pages do I need to read for the exam?" A very instrumentalist attitude towards their education generally and towards the information in particular. He failed the exam. Badly.
And don't get me started on spell-checkers....
