I don't know what your understanding of teaching is but essentially it is not as simple as you make out.
Girlfriend is doing her PGCE and I work with teachers day in day out.
On the issue of the computers. It was after all you who brought it up and you who failed to cite the data on just how many use them and for what. Maybe we don't know? Maybe what your saying about how they use them is an unfair generalisation? If you don't have the data - and the burden of proof is on you to back your arguement up. If your going to generalise to make a point about wastage you really should have more than anecdotal evidence...
Last year through to May this year I was involved in rolling out broadband to 171 schools, we're short staffed and I had to do it myself, it required IP changes at every single school, maybe schools still run static IPs (It's not upto us to decide whether they switch to DHCP or not sadly), therefore the fact I had to go round a few thousand machines - curriculum machines, administration machines and laptops - gives me a damn good idea of what school computers are used for, what kind of specs are out there and so on - if anyone has a good idea of what school computers and laptops get used for I sure as hell do.
Ok lets turn it around a bit. Since you seem to really hate this waste.... Maybe they should not have laptops. Maybe it would be a good thing? Perhaps then when I go to see my sister she will not be sitting to 10 and 11pm at night working on her laptop? All at the tax payers expense. Such a wonderful gift from the taxpayers to make sure she performs after all what better way to make someone feel as though they owe you something than to give them a 'gift'. After all its such a well paid and easy job. Just maybe your right Xest.
As stated above I've been to a lot of schools and met a lot of teachers, apart from the fact primary schools are almost entirely empty gone 4pm other than the odd teacher offering after school activies, the head and the secretaries the majority of the ones I've spoken to at primary level accept their job is pretty easy. Certainly it's a different story at secondary level where there's vastly more homework to mark and a lot, lot more pressure on ensuring kids acheive well in their GCSEs than there is on lower exams (although of course there is still some pressure). One primary school I went to is due to trial new times this year, by simply not having a lunchtime, starting 30mins earlier (iirc, maybe an hour earlier..) and finishing at 1:30pm. There aren't many jobs out there that give you a one off £3k - £10k payment when starting the job, let you work 8am to 1:30pm (or hell, even 8:30am to 3:30pm at that), give you over 3months off work a year, a decent pension and then on top of all that give you a perfectly respectable full time wage on top.
