The thread about how office jobs have changed got me thinking about how teaching has changed (apart from turning from a great job into a crap one...)
I started in 2003. Nobody used emails and we had internal memo envelopes used between buildings. This carried on for years! Not every room had a computer and we did registers on Bromcoms (handheld things, like overgrown Kindles, that did registers and you could also do reports etc on. They used AA batteries and were always running out of power! You'd have to send a kid down to the office for batteries if you didn't keep a secret stash).
No projectors, the odd Smart board which was regarded as the very height of technology (even though they were utterly shit to write on). Mobile phones weren't an issue as hardly any kids used them and even then they were basic ones. No name badges, no passes, no lanyards, all doors left unlocked all the time and half the site was barely even fenced.
People used to go to the pub on Friday after school and on my last day of teaching practice the department took me to the pub at lunchtime and we had a drink!
