Two Kinds of Obesity: Physical and Mental
One of a set of pessimistic or admonitory messages.

There is growing concern about obesity, especially in children. Here is one among many news reports on the subject

What most people seem not to have noticed is that there's another kind of obesity, a sort of 'mental obesity' which may be causing as much harm to the nation's health -- its mental and intellectual health.

Compare these two

If you don't believe me ask any university teachers who have been involved in teaching undergraduates over the last couple of decades or longer (at least in the UK, though I expect the problem is world-wide).

Or is the answer that fuddy duddies like me have no right to say what's good for the new generation?

As part of a discussion on the mailing list of CPHC, I offered the following suggestion for countering the above
Maybe there are too many forces for us to oppose, so that change will not happen until after some revolution-provoking disaster like escalation of global warming and/or drying up of major natural resources.

But perhaps there is some hope: if the problem is recognised. An example of a change that might move in the right direction: make sure that school children, especially the brightest school children, are NOT introduced to computers with widely used highly packaged operating systems and utilities. Instead go back to an updated version of the BBC micro (see the fascinating new MIT initiative http://pedia.media.mit.edu/wiki/One_Laptop_per_Child though I worry about the constraints of flash memory) and teach them

Restrict them to using relatively simple text editors and document formatters.

Allow simple text-based email (with provision for sharing diagrams) for discussion of problems and ideas, sharing of code, and collaborative production of documents.

Remove access to the web and search engines, except for very specific tasks where they learn how to write critical reviews of what they find on the internet, instead of merely quoting it.

That's off the top of my head and probably needs debugging. But I bet that all the people who write about teaching 'strategic subjects' and the need for 'highly skilled workers' are probably thinking of something very different from all that -- something which from this perspective is educationally disastrous: giving students PCs full of todays tools and teaching them to use them.

That's like teaching people how buy and cook pre-packed meals instead of teaching them chemistry.

I wonder how many people remember those sunday morning programs on BBC2 showing the amazing things that adventurous teachers and pupils did with computers in schools about 20 years ago or so, before they all started being taught to use word, internet explorer, powerpoint, spreadsheets, and other 'useful' packages which can easily fill up a curriculum and leave minds empty.

Around 30 years ago I made a prediction about how the educational power of computers would be used to transform us. How mistaken I was: all the wrong features of computers have been emphasised in education. See http://www.cs.bham.ac.uk/research/cogaff/misc/gc-ed.html

Related to this is a dire prediction I made when a company whose birth I was associated with celebrated its 20th birthday and invited memories and predictions. My prediction (for 2030) is here. Can people planning education be made to care?

A quite different sort of 'mental obesity' is discussed here http://members.aol.com/icgc/2003_INVENTION/2003-11-INVENTION.pdf
